How does chromosomal inheritance generate genetic variation in sexual reproduction?
Answer:
Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.
Answer:
Independent assortment
Explanation: When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other. This called is called independent assortment. It results in gametes that have unique combinations of chromosomes.

A bird that preys on moths is introduced to the habitat with moths and trees like the ones shown below.
Answer: c. The dark colored moths will experience disruptive selection.
Explanation:
The tree bark is light in color which means that while the light colored moths will be able to blend in, the dark colored moths will not. This will lead to the dark colored moths being hunted more by the bird leading to a sharp decrease in their numbers.
Disruptive selection occurs when an extreme trait is preferred over an intermediate one with little advantage in that environment. The dark moths will experience disruptive selection because the light moths are preferred for survival.

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%.

8.What is the other product produced in this image besides oxygen?
9. What will happen to the amount of oxygen if the amount of sun increases?
Answer:
8. Glucose (C6H12O6)
9. The plant will synthesize more, thus increase the amount of oxygen until a limiting factor prohibits the plant from synthesizing that much oxygen.
Explanation:
Glucose is the other product produced in this image besides oxygen.
What are the functions of glucose?Glucose is the main type of sugar in the blood and is the major source of energy for the body's cells. Glucose comes from the foods we eat or the body can make it from other substances. Glucose is carried to the cells through the bloodstream.
Glucose monosaccharides (not as part of starch) are also found naturally in some foods. The most concentrated whole food source of glucose monosaccharides is honey, followed by dried fruits such as dates, apricots, raisins, currants, cranberries, prunes and figs.
Glucose consists of three elements such as carbon, hydrogen and oxygen. 6 carbon atoms bonded together as a chain with additional atoms of oxygen and hydrogen.

How are humans changing the carbon cycle?
Humans are planting more trees to add more oxygen to to the carbon cycle.
Humans are adding carbon to the Earth by over-farming,
Humans are burning carbon and putting it into the atmosphere.
Humans change the carbon cycle by burning carbon and putting it into the atmosphere. Thus, the correct option for this question is C.
What is the Carbon cycle?The carbon cycle may be defined as a type of biogeochemical cycle through which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. This cycle governs the exchange of carbon and its derivatives among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
The activity of Plants in the carbon cycle is determined by the fact that they breathe carbon dioxide. Humans are often cutting them down and the carbon dioxide stays in the air.
Apart from this, the burning and combustion of fossil fuels, trees, and chemicals increase the level of carbon in the atmosphere. Due to these human actions, the carbon cycle may be changing gradually.
Therefore, the correct option for this question is C.

Meiosis is a type of cell division in germinal cells. It produces gametes that contain one complete haploid set of chromosomes. Thus, option B is correct.
What is meiosis?Meiosis is a reductional cell division that occurs in the reproductive or the germinal cells to produce the daughter cells with a haploid (n) set of the genetic material.
The chromosome gets halved and reduced by number in the meiosis I phase of the division. Here, the homologous chromosomes separate and enter daughter cells that are called the gametes.
Therefore, in meiosis, the gametes produced have half the number of chromosomes.

why is vacuole in plant cell larger than a vacuole in an animal cell?
Answer:
The plant has the largest vacuole than animal cells because in plant cells the larger central vacuole performs two functions, one is to store water and the other is to help the plant remain upright. In animal cells, vacuoles are smaller but more in number because they do not require vacuole for rigidity or pressure.
