Answer:
Genetic variation is increased by meiosis
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. ... A gamete will end up with 23 chromosomes after meiosis, but independent assortment means that each gamete will have 1 of many different combinations of chromosomes
Explanation:
Due to the possibility of genetic material being recombined and shuffled during meiosis, having genes on several chromosomes as opposed to only one chromosome enhances genetic variety among kids.
What is genetic variation among offspring?At locations known as chiasma, the chromosomes overlap. The chromosomes split and reunite at each chiasma, exchanging part of their genes in the process. Genetic diversity comes from this recombination.
The chromosomes align in pairs and cross over during the meiotic process to exchange genetic material. This process results in novel gene pairings on the chromosomes, which can result in the birth of kids with distinctive combinations of features.
Therefore, the possibility of genetic material being recombined and shuffled during meiosis increases genetic variation among offspring.

2. Which of these practices helps cut down on waste?
A) O Reduce
B) O Reuse
C) O Recycle
DO All of the above
Reduce, reuse, and recycle all of these practices helps cut down on waste, Reducing the quantity of garbage we generate is made easier by following the three R's of reduce, reuse, and recycle, hence option D is correct.
How to reduce waste?They preserve energy, landfill space, and natural resources. Additionally, communities need less land and money to dispose of waste in landfills when they follow the three R's.
Reduce refers to reducing the quantity of waste we produce. Finding new uses for items that would have otherwise been thrown out is meant by reuse.
Recycling refers to the process of converting waste materials, such as plastic milk bottles, into new, valuable materials (like picnic benches, playground equipment, and recycling bins).
Therefore, option D is correct.

when the body removes carbon dioxide bu the way of respiratory system what happens to the ph of blood
the more carbon dioxide in the blood the more acidic it will be. so when it is removed the acidity will decrease.
so the pH increases
When the body removes carbon dioxide, the PH of blood increases
The body control the blood's acid-base balance through different ways. The organs used for this control is lung, kidney and buffer systems.
The lung can control blood pH through the release of carbon dioxide. Carbon dioxide acidic and its accumulation in the body leads to an increase in PH.
When the blood PH is too low (i.e. acidic), the body increases breathing so as to expel(remove) more carbon dioxide thereby increasing the PH of the blood.

According to the graph, what would be the approximate rate of photosynthesis for
plants that grow in this environment? What other factors would affect a plant's
survival?
Answer:
Light, temperature, water, humidity, and nutrition.
Explanation:
the higher rate of photosynthesis for plants occurs that grow in the desert environment if other factors such as water, nutrients etc are also available for plants. Due to high intensity, the plants produces more food and as a result the growth of the plant increases. If water is not available for desert plants, the photosynthesis is slower down if the intensity of light is higher. Light, temperature, water, humidity, and nutrition are the factors that affect the survival of plants.
