Answer:
Both genes would be likely to go to fixationThe term for this process is "linked genes"The reason to suspect that both of these genes may not go to fixation is that they are too close to the mutation and the recombination frequency between them is very very low.Explanation:
Independent assortment law establishes that the alleles from two or more different genes distribute in gametes independently from each other. In other words, a gamete receives an allele from a gene that does not depend nor influence the allele of another gene in the same gamete. This can only be applied to independent genes. These genes segregate independently after crossing-over because they are located far away from each other.
Some other genes, however, are too close to each other and they do not segregate independently. These are the linked genes that do not exhibit an independent distribution, and they inherit together more frequently.
Crossing-over between linked genes that are very close to each other in the chromosome is not that common. Crossing-over during meiosis occurs randomly in different positions all along the chromosome, and its occurrence frequency in the area between two genes depends on the distance between them. A short distance between genes is a very little target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated between each other.
Two genes that are very close will have a few recombination events and are strongly bounded.
The more separated two genes are, the more chances of recombination there will be. The closer they are, the fewer chances of recombination there will be.
Genes that express 50% of recombination frequency or more are not linked genes.
To analyze the recombination frequency, we have to know that
1% of recombination = 1 map unit = 1centi Morgan = 1,000,000 base pairs.
And that the maximum recombination frequency is always 50%.
The map unit is the distance between the pair of genes for which every 100 meiotic products one of them results in a recombinant one.
In the exposed example we know that the distance of gene A from the mutation is 100 base pairs, and the distance of gene B from the mutation is 1000 base pairs.
1,000,000 base pairs ------------------ 1% recombination frequency
1000 base pairs -----------------------X = 0.001% recombination frequency
100 base pairs ------------------------ X = 0.0001% recombination frequency
According to the recombination frequency between the mutation and gene A, and between the mutation and gene B, we can assume that both genes are linked to the mutation, as they seem to be too close to it. They are so close, that their recombination frequency is very little.

Sodium is an example of an alkali metal. The alkali metals are found in the leftmost column of the periodic table, known as Group 1. Use the interactive periodic table to explore the properties of the following alkali metals: lithium (Li), sodium (Na), potassium (K), rubidium (Rb), and cesium (Cs). The animations demonstrate a chemical property common to alkali metals: they react with water. How does the reactivity vary among this group of elements? Why might patterns like this be useful to scientists?
Answer:
The reactivity greatens the farther you go down on the periodic table. Lithium will have the weakest reaction, and cesium will have the greatest reaction. Patterns like this are useful to scientists because it shows which elements are the most reactive and which aren't. The farther down and to the left you go within the periodic table, the more reactive the elements become. The farther up and to the right you go, the less reactive they become.
Explanation:
The reactivity of alkali metals increases down the group. Periodic trends help scientists to predict the reactivity of newly discovered elements.
In group 1, reactivity of elements increases down the group because as you go down the group more shells are added thereby making it easier to remove the outermost electron.
This explains the increase in chemical reactivity from Lithium to cesium.
These periodic trends are very important in predicting the chemical reactivity of newly discovered elements that are added to a group.

Giving a few canned goods to the local food bank for its annual food driveReciprocity
Helping someone move her couch after she helped you study for an upcoming examThe biological relationship between cleaner fish and large predators in the ocean, in which cleaner fish keep the predatorExplanation:
Altruism is a biological concept used to describe the action of an organism which reduces its own fitness but increases the fitness of another organism. Reciprocity, on the other hand, refers to cooperation between two unrelated organisms in which the beneficial actions of one to the other is reciprocated either in the short or medium term.
Giving a few canned goods to the local food bank for its annual food drive is an action done to benefit those that patronize the food bank without any hope of it being reciprocated. Hence, it is considered altruism.
Helping someone move her couch after she helped you study for an upcoming exam and the biological relationship between cleaner fish and large predators in the ocean, in which cleaner fish keep the predator are both considered reciprocity.

A certain plant species has seeds that remain dormant until heat stimulates them to germinate.
• Describe the process of succession that could occur with this species after a wildfire.
• Identify whether the plant species is dependent on succession events and explain how you know.
Answer:
Explanations: primary succession will take place because these plants will dominate after a wild fire has occured in the area since their growth is stimulated by heat hence the heat will result to the widespread of this type of plant
These plants are indeed dependant on succession events because they are only stimulated to grow through heat events
Secondary succession is that process which occurs after wildfires.
What is Secondary succession?In this type of ecological succession, the plants and animals recolonize a habitat after a major disturbance such as a devastating flood, wildfire, landslide, lava flow, or human activity etc.
Yes, the plant species is dependent on succession events because that event make the environment suitable for the growth of some plants so we can conclude that Secondary succession is that process which occurs after wildfires.

a. is masked by the recessive trait
b. masks the recessive trait
Answer:
b. maks the recessive trait
Quick explanation:
The dominant trait masks the reccessive gene, but the person still has the gene, it just won't affect them, it might affect their future generations. For example, the trait for blue eyes is a recessive trait, so in order for you to have blue eyes, both parents will need to have the gene for blue eyes.
The increase in the reproductive success of a species will have the greatest impact on the - size of that species’ population. competition within other communities in the biosphere.. success of other populations in the community. tissues that comprise organisms of that species.
Answer:
size of that species’ population.
Explanation:
The increase in the reproductive success of a species will have the greatest impact on the size of that species’ population.
A reproductive success rate means more individuals survive birth and get added to the existing population. The more the number of individuals added to a population, the more the size of the population of the species.
An increase in the population size of a species will only increase intra-species competition for resources but have no real impact on the success of other populations in the community.
If you ate more food from secondary consumers, how would this change the percentage of the biomass pyramid necessary to support your survival?
Answer:
would increase
Explanation:
The pyramid of biomass is a diagram that exhibits the total biomass of the organisms at different trophic levels, which are required to support life in a given ecosystem. This pyramid usually starts with producers situated on the bottom (e.g., plants), then continues with the organisms that eat these primary consumers (herbivores), after with secondary consumers (carnivores), and so successively. The pyramid of biomass indicates the amount of mass of 1-primary producers required to support the life of the primary consumers, 2- primary consumers needed to support the life of the secondary consumers, 3-secondary consumers needed to support the life of the tertiary consumers, and so successively for each trophic level. In this diagram, the trophic level with a higher amount of biomass (and energy) is usually represented by the producers (i.e., by organisms on the bottom), and this amount of biomass decreases as long as more levels are considered. In consequence, if more food from secondary consumers is consumed, it will produce an increase in the percentage of biomass that is needed to support life.

d. Protein movement is limited by the presence of a diffusion barrier
Answer:
The correct answer is option d. "Protein movement is limited by the presence of a diffusion barrier".
Explanation:
There are transportation mechanisms that allow to take up nutrients to the apical surface of the epithelial cells. The transportation process is best describes as protein movement limited by the presence of a diffusion barrier. There are structures known as tight junctions, located just below the apical surface . These tight junctions acts as diffusion barriers, separating the extracellular fluids surrounding the apical and basolateral membranes.
Please I need a comparison table between plant cells and plant tissues
Answer:
Plant tissues are collections of similar cells performing related functions. Different plant tissues will have their own specialized roles and can be combined with other tissues to form organs such as flowers, fruit, stem, and leaves. Two major types of plant tissue include meristematic and permanent tissue.
Meristematic tissue, the primary growth tissue in plants, is capable of self-renewal and indefinite cell division. Every cell in the plant originates from a meristem. Meristematic tissue is classified into one of three types depending on its location inside the plant - apical, lateral, and intercalary. Apical meristems are meristematic tissue located at the tip of root and stem, which enable elongation of plant length. Lateral meristems are present in the radial portion of the stem and root and increase the thickness or girth of the maturing plant. Intercalary meristems occur only in monocots at the base of the internode and leaf blade. The intercalary meristems increase the length of the leaf blade.

Sugar made in the process of photosynthesis to sent to the mitochondria to produce _____.
Answer:
energy
Explanation:
i just know it. i like science
Sugar produced in the process of photosynthesis to sent to the mitochondria, is used to produce energy in the form of ATP through the process of cellular respiration.
What is Cellular respiration?
Energy is produced in the body through the food we eat. The food is broken down into simpler substances which are absorbed by the cells and in the cells are used to produce energy.
Sugar is produced by the process of photosynthesis in plants which is sent to the mitochondria to produce energy in the form of ATP (adenosine triphosphate). The process of oxidation of food to produce ATP is called cellular respiration.
The process of cellular respiration consists of three processes which include glycolysis (breakdown of glucose into pyruvate), citric acid cycle, and the oxidative phosphorylation which produces about 34-36 molecules of ATP in the mitochondria of cell.

Which two factors are responsible for seasons on Earth?
A. Greenhouse gases and ozone in the atmosphere
B. Earth's tilted axis and its rotation around it
C. Trade winds and sea breezes
D. Earth's tilted axis and its revolution around the sun
Answer:
D
Explanation:
The short explanation is how the earth is tilted towards the sun, and it's revolution will cause certain parts to be closer or farther relatively to the sun. Hope this helps
The change in season is brought on by the earth's tilted axis and its revolution around the sun. Therefore, option (D) is correct.
The seasons are caused by Earth's tilted axis. Different regions of the Earth are exposed to the Sun's strongest rays at various times of the year. Therefore, the Northern Hemisphere experiences summer when the North Pole tilts toward the Sun. Additionally, winter in the Northern Hemisphere occurs when the South Pole tilts toward the Sun.
The Northern Hemisphere experiences summer in June because the Sun shines more intensely there than at any other time of the year. The Northern Hemisphere experiences winter in December because it is the month when the South Pole is oriented toward the Sun.
Therefore, option (D) tilted axis and revolution are reasons for the seasons.

You can also complete the project using poster board. Either way is fine. Once completed with poster board, you must send it to me by taking a picture through an email.
The key to the assignment is to make sure you will model the structures of the cell and describe their functions. You will do this by completing a table that describes the functions of structures of the cell. The table should also identify factory parts or workers that have similar functions.
The comic strip is just a way to describe the cell structures. It's a scenario (scene) describing the events. The scene is of a reporter who visits a cell “factory” and interviews someone about the structures/organelles and how their roles in the cell are similar to those of a factory and its workers.
