Answer:
mutation and recombination
Explanation:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

discuss the stages of the cell cycle mechanism that regulate it and how this cycle is related to the growth and maintenance of organisms
Answer:
The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.
Cyclins regulate the cell cycle only when they are tightly bound to Cdks. To be fully active, the Cdk/cyclin complex must also be phosphorylated in specific locations. Like all kinases, Cdks are enzymes (kinases) that phosphorylate other proteins. Phosphorylation activates the protein by changing its shape.

Which of the following statements is correct regarding the reactants and products for photosynthesis and cellular respiration?
Carbon dioxide and water are reactants in photosynthesis and products of cellular respiration.
Carbon dioxide and water are reactants in cellular respiration and products of photosynthesis.
Carbon dioxide is a reactant of cellular respiration, and water is a product of photosynthesis.
Carbon dioxide is a product of photosynthesis, and water is a reactant in cellular respiration.
Answer:
the answer is C
Explanation:
The type of the respiration that are taking place inside the cells are called as the cellular respiration in which carbon dioxide is the reactant and the water along with it is the bi product. The correct answer is option C.
What are the two products in the process of photosynthesis ?
The products of photosynthesis are oxygen that is released out with the glucose that is the sugar molecule which is the stored form of energy.
Photosynthesis converts out carbon dioxide and the water into the oxygen and typically glucose. Glucose is then used as the food by plant and the oxygen that is a by-product of the process. Cellular respiration later just converts out oxygen with the glucose into the water and carbon dioxide.
Water and the carbon dioxide are just the by- products along with the ATP that is the energy which is just transformed out from process. In the process of the cellular respiration where the glucose and oxygen together just reacts in order to form the ATP. Water and the carbon dioxide are just released as the byproducts.

In determining probabilities all you need to do is count and then divide by the number of results.
What is punnett square?A Punnett Square is a useful tool for forecasting the changes and probabilities that can result from cross-breeding. This includes foreseeing the mating of different species, including humans and animals.
It is asking the chances of having green seeds and that's the recessive allele. For recessive traits to be expressed, there can't be a dominant trait next to it because the dominant trait will always be expressed. So the expected result should be yy (two lowercase) if you want the recessive trait to be expressed.
In the Punnett square of the second generation, there is 1 out of 4 yy genotype. So then divide 1 by 4 and multiply it by 100% to get the probability in percent. So in short, the answer is 25%.

What adaptations are common for animals in hot and cold climates? Name at least two for both hot and cold climates.
Answer:
Explanation:
1. hot- camels live in hot deserts where its extremely hot and sandy therefore they have long eyelashes to protect their eyes just in case of sand storms
2. cold- penguins live in very cold climates so they have both black and white fur white so they can disguise in the snow from predators and black so they can absorb heat from the sun when they get extremely cold
3. hot -thick fur on the top of the body for shade, and thin fur elsewhere to allow easy heat loss. a large surface area to volume ratio - to maximise heat loss. the ability to go for a long time without water - they lose very little water through urination and perspiration. the ability to tolerate body temperatures up to 42°C
The “Rule of 10” states that as little as ________ % of the energy at any trophic level is transferred to the next trophic level.

The majority of the energy is lost as ________________ through the completion of metabolic processes.
Answer:
1) "Rule of 10" states that as little as 10% of energy is transferred
2) Higher trophic level organisms need to eat MORE food, as energy is lost between trophic levels

Describe how these three types of soil differ in terms of particle size, water-holding capacity, and
surface area for nutrient absorption by roots.
Answer:
Soils with smaller particles (silt and clay) have a larger surface area than those with larger sand particles, and a large surface area allows a soil to hold more water. In other words, a soil with a high percentage of silt and clay particles, which describes fine soil, has a higher water-holding capacity.

Explain how endospores have allowed some bacteria, like tetanus, to be a successful species.
Answer:
Endospores allow Clostridium tetani (causative agent of tetanus) to survive harsh conditions in the environment. Because tetanus is an obligate anaerobe, oxygen is a harmful environmental factor. Endospores also allow the bacteria to resist desiccation (drying) and high temperatures.
The bacteria can be dormant as endospores until they are in favorable conditions. At this point, they will germinate into vegetative cells where they will be able to reproduce until conditions become unfavorable and they form endospores again.
