please help!!! worth 30

Answers

Answer 1

Sure, I can help you with that! Here are the steps to calculate the allelic and genotypic frequencies for the population of rabbits:

First, let's define some terms:

Allele: a variant form of a gene that occurs at the same position on a chromosome.

Genotype: the combination of alleles at a particular gene locus.

Frequency: the proportion of individuals in a population that have a certain genotype or allele.

Now, let's use the information provided in the question to calculate the allelic and genotypic frequencies:

The allelic frequency (p) of the dominant black allele is 0.22 / (0.22 + 0.78) = 0.22 / 0.90 = 0.242 (rounded to four decimal places).

The allelic frequency (q) of the recessive white allele is 0.78 / (0.22 + 0.78) = 0.78 / 0.90 = 0.861 (rounded to four decimal places).

The frequency of the black/black (BB) genotype is 0.22/0.78 = 0.289 (rounded to four decimal places).

The frequency of the white/white (ww) genotype is 0.78/0.78 = 1.000 (rounded to four decimal places).

To calculate the genotypic frequencies, we need to combine the alleles for each genotype:

The genotype BB has one black allele and one black allele, so its genotypic frequency is 1 x 1 = 1.

The genotype WW has two white alleles, so its genotypic frequency is 2 x 2 = 4.

Now we can calculate the overall frequency of each genotype in the population:

The frequency of the BB genotype is 1 / (0.22 + 0.78) = 0.454 (rounded to four decimal places).

The frequency of the WW genotype is 4 / (0.22 + 0.78) = 0.546 (rounded to four decimal places).

So, the allelic frequency of the dominant black allele is 0.242, and the allelic frequency of the recessive white allele is 0.758. The genotypic frequency of the BB genotype is 1, and the genotypic frequency of the WW genotype is 4.

How can you evaluate the relationship between a decomposer and a dead body?

Answers

The relationship between a decomposer and a dead body is essential for the natural environment to be in balance. Decomposers such as bacteria, fungi, and scavengers break down the dead body, releasing nutrients and energy back into the environment.

This process is known as decomposition and it is essential for the cycle of life. Decomposers break down the dead body, releasing nutrients and energy back into the environment and so, preventing the buildup of waste. The nutrients released can be taken up by other organisms in the environment, including plants which then produce more food for animals.

This cycle of decomposition and nutrient release is essential for the balance of the environment. Without decomposers, dead bodies would accumulate and cause an imbalance in the environment, resulting in disease and death of other organisms.

A delivery driver nearly got into a car accident. After the incident, his heart starting to race and the driver also felt a rush of adrenaline. What systems interact with each other to cause this rush of adrenaline?

Answers

The body’s response to stress and danger is a complex interaction between the sympathetic nervous system and the endocrine system. In response to a perceived threat, the sympathetic nervous system is activated, releasing hormones such as adrenaline.

Adrenaline is a hormone that is released by the adrenal glands in response to stress or fear. This hormone acts as a stimulant, increasing heart rate, blood pressure, and respiration, and increasing the body’s sugar levels. This helps the body prepare for fight or flight. In the case of the delivery driver, the rush of adrenaline helped him to react quickly and avoid the accident.

The endocrine system, which includes the adrenal glands, also helps to regulate the body’s response to stress. This system releases hormones that help the body cope with stress, such as cortisol, which helps to reduce the body’s stress response. Together, these systems work together to help the body respond to stress and danger and help the delivery driver avoid the accident.

What is the relationship between species diversity and ecosystem resilience?

Answers

Species diversity is an important factor in the resilience of an ecosystem. The more diverse the species in an ecosystem, the greater the ability of the ecosystem to withstand changes in the environment such as changes in temperature, food supply, and water quality.

A diverse species mix provides a greater variety of organisms that can fill different roles in the ecosystem, allowing the ecosystem to adapt more easily to changing conditions. Diverse species also provide a greater number of predators and prey, which helps to maintain a balance between populations.

With a greater number of species, there is also a greater variety of genetic material, which can help the ecosystem to evolve and adapt more quickly to new conditions. The greater the species diversity, the more resilient the ecosystem will be.

In cats the trait for hair length is controlled by gene S, where the dominant allele(S) results in short hair and recessives have long hair. The W gene is known as the "masking" gene because a cat that has a dominant W allele in its genotype will have an all-white coat due to a lack of melanin in its skin. Cats with a ww genotype can have a coat of any color, depending on the inheritance of other genes that determine coat color.


A male with long hair and a white coat is crossed with a female cat with short hair and a white coat. The owner of the cats has heard about the masking gene and believes that the cross will produce a litter of all-white kittens, some with short hair and some with long hair.


(a) is the owner's prediction accurate? give evidence to support your response.

(b) Based on the given information, determine all of the possible genotypes of the kittens in the litter

Answers

(a) The owner's prediction is not accurate.

(b) The possible genotypes of the kittens in the litter are SSWW, SSWw, and SSww.

A. The W gene is a dominant gene that masks the expression of other genes, such as the S gene. Therefore, even if both parents have the same genotype for the S gene, the presence of a dominant W gene will result in all of the kittens having a white coat. Therefore, there will not be any kittens with a long-haired coat in the litter, since the W gene masks the expression of the S gene.

B. The SSWW genotype would result in all of the kittens having short hair and a white coat. The SSWw genotype would result in some kittens having short hair and a white coat and some kittens having long hair and a white coat.

The SSww genotype would result in all of the kittens having long hair and a white coat. Therefore, it is possible that the litter could contain any combination of the three genotypes.

how might this affect the allele frequencies of the banding gene over time?

Answers

Over time, the allele frequencies of the banding gene could be affected in a number of ways. If the environment changes, such as if there is an increase in the amount of food available, then the allele frequencies of the banding gene could shift as the individuals with a particular allele may be more successful in mating and passing on their genes.

Additionally, if there is an increase in the number of predators, then the allele frequencies could also shift as individuals with certain alleles may be more successful in avoiding predation. Finally, if there is a change in the climate, then the allele frequencies could shift as individuals with certain alleles may be better suited to the new conditions.

Ultimately, these changes in allele frequencies will depend on the environmental conditions and the success of individuals with particular alleles.

Answers

La Niña is a climate pattern that occurs in the Pacific Ocean, characterized by cooler-than-average sea surface temperatures in the central and eastern parts of the ocean.

During a La Niña event, the trade winds blowing across the Pacific become stronger, causing more warm water to pile up in the western Pacific. This results in a cooler sea surface temperature in the eastern Pacific.

The increased trade winds also lead to more upwelling of colder, nutrient-rich water along the western coast of South America, which can lead to changes in ocean currents, weather patterns, and precipitation in various regions of the world.

How motorcyclists think people react to them funny.

Answers

Motorcyclists often think that people react to them strangely because they are not used to seeing a person on a motorcycle on the road.

This can lead to motorists suddenly changing lanes in front of a motorcyclist, or not leaving enough space when passing. Additionally, motorcyclists may feel like drivers are not aware of their presence on the road, which can make them feel vulnerable and unprotected. Another reason motorcyclists think people react to them strangely is because of the stereotypes associated with motorcyclists. Some people may view motorcyclists as reckless or dangerous, which can lead to negative reactions from other drivers. This stereotype can also make it difficult for motorcyclists to get the respect they deserve on the road.

Difference between excitatory and inhibitory neurotransmitters.

Answers

Neurotransmitters are chemical messengers in the nervous system that allow communication between neurons. Excitatory neurotransmitters increase the likelihood that a neuron will fire an action potential and continue the signal, while inhibitory neurotransmitters decrease the likelihood of firing an action potential and stop or decrease the signal.

Excitatory neurotransmitters, such as glutamate, bind to receptor sites on the postsynaptic neuron and cause depolarization, making the neuron more likely to fire an action potential. Inhibitory neurotransmitters, such as GABA, bind to receptor sites and cause hyperpolarization, making the neuron less likely to fire an action potential.

The balance of excitatory and inhibitory neurotransmitters is important for maintaining proper neural function and disruptions in this balance can lead to various neurological disorders.

“The l form of pyruvate kinase is more likely to become phosphorylated in the presence of high levels of glucagon” is true, because the l form is more likely to become phosphorylated in the presence of high level of glucagon, option (B) is correct.

Glucagon signals the liver to release glucose into the bloodstream, and phosphorylation of pyruvate kinase in the liver helps to prevent glycolysis and instead promote gluconeogenesis, which is the production of glucose from non-carbohydrate sources.

On the other hand, the m form of pyruvate kinase is more likely to become phosphorylated when glucagon levels are high, which is consistent with the role of glucagon in promoting glycogen breakdown in muscles to release glucose for energy. Option (B) is correct.

Explanation:Based on the given chemical equation:

3H2 + 2C12 -> HCINo, this equation is not balanced.A balanced chemical equation has the same number of atoms of each element on both sides of the equation. In this equation, the number of hydrogen atoms (H) and chlorine atoms (Cl) are not equal on both sides.On the left-hand side (LHS), there are 3 molecules of hydrogen gas (H2), which means a total of 6 hydrogen atoms (3 x 2 = 6). However, on the right-hand side (RHS), there is only 1 hydrogen atom in hydrochloric acid (HCI). So, the number of hydrogen atoms is not balanced.Similarly, on the LHS, there are 2 molecules of chlorine gas (Cl2), which means a total of 4 chlorine atoms (2 x 2 = 4). However, on the RHS, there is only 1 chlorine atom in hydrochloric acid (HCI). So, the number of chlorine atoms is also not balanced.In a balanced chemical equation, the number of atoms of each element must be the same on both sides of the equation, following the law of conservation of mass. To balance this equation, coefficients (numbers in front of the chemical formulas) can be adjusted to ensure that the number of atoms of each element is the same on both sides. For example:3H2 + 2Cl2 -> 6HCINow, the equation is balanced as there are equal numbers of hydrogen and chlorine atoms on both sides of the equation.

Indicate the pathway of urine formation to urine output by placing each of the structures in the correct sequential order from left to right.

Answers

The correct sequential order of the pathway of urine formation to urine output is as follows:

Renal corpuscle → Proximal convoluted tubule → Loop of Henle → Distal convoluted tubule → Collecting duct → Renal pelvis → Ureter → Urinary bladder → Urethra → External urethral orifice

Urine formation begins in the renal corpuscle, where blood is filtered to remove waste products and excess water. The filtrate then flows into the proximal convoluted tubule, where essential molecules such as glucose and amino acids are reabsorbed into the bloodstream.

Next, the filtrate enters the loop of Henle, where water and ions are exchanged to concentrate the urine. The filtrate then enters the distal convoluted tubule, where additional water and ions are exchanged to further concentrate the urine.

The collecting duct receives the concentrated urine from several nephrons and transports it to the renal pelvis. From the renal pelvis, the urine flows through the ureter and into the urinary bladder for storage.

Finally, the urine is expelled from the body through the urethra and external urethral orifice during urination.

The origin of the oceans during Earth's early history can be explained in four steps.

Step 1: When the early Earth was forming some 4.6 billion years ago, there were no oceans and it was a hot, dry region.

Step 2: As the Earth cooled, water vapour emitted by volcanoes and other natural sources began to condense onto the surface of the planet as liquid water.

Step 3: Eventually, the first seas were created when this liquid water gathered in low-lying locations. Scientists disagree on the precise timing and method of ocean formation, although it most likely took place between 3.8 and 4 billion years ago.


Step 4: After the seas developed, they significantly influenced the climate, chemistry, and life of the early Earth. They functioned as a habitat for the first living things, a source of nutrients and minerals for the planet's ecosystems, and helped control the temperature and carbon dioxide levels in the atmosphere.
