Bacteria are only able to be produced from other bacteria already existing on earth.
Which theory best describes this?
Answer:
Bacteria reproduce by binary fission. In this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). Bacteria do not grow and multiply the same way as animals or humans. They take in nutrients and reproduce by dividing – one bacteria splits and becomes two bacteria, two become four, four become eight and so on.
Explanation:
A black chicken and a white chicken are crossed. What is the probability that they will have erminette chicks?
Answer:
[tex]Probability = 100\%[/tex]
Explanation:
Given
Crossing of a black chicken and a white chicken
Required
The probability of having erminette chicks
The genotype of a black chicken is represented as: BB
The genotype of a white chicken is represented as: WW
The genotype of an erminette chicken is represented as: BW
Using a Punnett square, we have:
[tex]\begin{array}{ccc}{} & {B} & {B} & {W} & {BW} & {BW} & {W} & {BW} & {BW}\ \end{array}[/tex]
The result of crossing the two chicken gives 4 BW out of a total of 4
i.e 4 erminette chickens out of 4 possible chickens
So, the probability is:
[tex]Probability = \frac{4}{4}[/tex]
[tex]Probability = 1[/tex]
Represent as percentage:
[tex]Probability = 100\%[/tex]

what is the movement that helps the movement of undigested food through the large intestine?
Answer:
Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move. The movement pushes food and liquid through your GI tract and mixes the contents within each organ.

How does acid rain (deposition) form and travel to effect the environment?
Answer:
The ecological effects of acid rain are most clearly seen in aquatic environments, such as streams, lakes, and marshes where it can be harmful to fish and other wildlife. As it flows through the soil, acidic rain water can leach aluminum from soil clay particles and then flow into streams and lakes.

I need URGENT help with 16 through 18 pls!!!
Answer:
16. Directional Selection
17. Disruptive Selection
18. Stabilizing Selection
19. Natural Selection
20. Adaptation
Explanation:
In population genetics, directional selection/positive selection is a mode of natural selection in which an extreme phenotype is favored over other phenotypes.
Disruptive Selection would show phenotypes (individuals with groups of traits) of both extremes but have very few individuals in the middle.
Stabilizing Selection. Occurs when individuals at the extremes of the range of characteristic are selected against. This means that the "average" individuals are selected for.
A specific characteristic that an organism can pass on to its offspring through its genes is called a

Which of the following best predicts and justifies how the proportion of the Tibetan population with big blood vessels living in the mountains will change over the next 1,000 years (assuming conditions remain stable)?
Question 2 options:
I predict that the proportion of individuals with big blood vessels living in the mountains will decrease because there is a variation in blood vessel size and those with the smaller blood vessels can store more red blood cells than larger vessels, so more oxygen can be moved to the body cells. Therefore, they have a better chance of surviving and passing this trait on to their offspring.
I predict that the proportion of individuals with big blood vessels living in the mountains will stay the same because there is a variation in blood vessel size and that variation will remain in a population. The is what is so cool about humans, we are all so unique.
I predict that the proportion of individuals with big blood vessels living in the mountains will increase because there is a variation in blood vessel size and those with the bigger blood vessels can deliver more oxygen to the body cells and therefore have a better chance of surviving and passing this trait on to their offspring.
I predict that over 1,000 years, the proportion of individuals with big blood vessels living in the mountains will not change because a change can’t happen to an individual, an individual can only increase the amount of red blood cells it makes, not its blood vessels.
Answer:
Over 1,000 years, the proportion of individuals with big blood vessels living in the mountains will not change because a change can’t happen to an individual, an individual can only increase the number of red blood cells it makes, not its blood vessels.
Explanation:
Evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection
What is blood vessels?
The blood vessels are the components of the circulatory system that transport blood throughout the human body.
I predict that over 1,000 years, the proportion of individuals with big blood vessels living in the mountains will not change because a change can’t happen to an individual, an individual can only increase the amount of red blood cells it makes, not its blood vessels.

Which surface was warmer during the month of October? The pond or the sidewalk?
Answer:
The pond was warmer during the month of October.
Explanation:
Water has a high specific heat capacity, therefore more heat is required to change its temperature. This is why aquatic life is able to stay alive even when temperatures drop drastically. The sidewalk however, will more than likely adapt to the temperature change quickly as concrete does not have a very high specific heat capacity.

Write a 200-word report on your research, using proper grammar, correct spelling, and appropriate punctuation. Make sure you include:
A definition of overgrazing
A discussion on the damage overgrazing can cause
The advantages and disadvantages of each type of grazing
A discussion on the type of grazing you select to use, which includes your justification of why you selected the grazing strategy
Answer:
answer is in explanation before
Explanation:
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. Overgrazing combined with overstocking has the most damaging outcomes to the world’s natural environment. The scarcity of water resources, water pollution, degeneration of coral reefs, and eutrophication are all connected to overgrazing. The chief polluting elements include farm chemicals and animal wastes.
Types of grazing systems 1. Types of grazing systems Grazing animals (such as cattle, sheep and goats) feed on the leaves and shoots of grass... 2. Zerograzing In this type of grazing system, the animals are not allowed to go out into the pastureto graze.
Overgrazing is defined as the practice of allowing too many livestock to graze on a particular area of land for an extended period. This leads to a decrease in the vegetation cover and the soil's capacity to hold moisture, which results in soil erosion and desertification.
What is overgrazing?There are three types of grazing systems: continuous grazing, rotational grazing, and intensive grazing. Continuous grazing involves leaving livestock on a particular area of land throughout the year. Rotational grazing involves rotating livestock to different areas of land to prevent overgrazing. Intensive grazing involves keeping livestock in smaller paddocks and rotating them frequently.
Hence, overgrazing is defined as the practice of allowing too many livestock to graze on a particular area of land for an extended period. This leads to a decrease in the vegetation cover and the soil's capacity to hold moisture, which results in soil erosion and desertification.

when are chromosomes (dna) copied?
Answer:
Interphase begins with G1 (G stands for gap) phase. During this phase, the cell makes a variety of proteins that are needed for DNA replication. During S phase, which follows G1 phase, all of the chromosomes are replicated. Following replication, each chromosome now consists of two sister chromatids.
Have a good day. :)
Answer:
Chromosome replication
Explanation:
Chromosome replication is a key event during the cell cycle that must be completed before a cell divides. To reproduce successfully, every cell must replicate its chromosome and distinguish these sister chromosomes from one another.

Use the images below to answer the question. 2. What makes all of the samples different from each other?
Answer:
Shape and structure.
Explanation:
The difference in shape and structure of these pictures is responsible for the difference from each other. The organisms present in these pictures are different in their size, shape and composition of their body. Some are small and some are large, some are living while the others are non-living, some are very hard whereas the others are soft and fleshy. So the organisms present in these samples are different from each other in a variety of ways i.e. size, shape and body structure.
