Explanation:
Why is sexual reproduction associated with meiosis? meiosis reproduces identical DNA meiosis is the complete process of sexual reproduction meiosis helps to generate variability meiosis produces gametes
Answer:
meiosis produced gametes
Explanation:
During sexual reproduction, meiosis generates genetic variation in offspring because the process randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gamete. The two gametes then randomly fuse to form a new organism.

Why is it important for your brain to control many functions automatically?
Answer:
The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you're less aware of — like the beating of your heart and the digestion of your food.
Think of the brain as a central computer that controls all the body's functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part.
Explanation:
If you brain does not, or is unable to perform multiple tasks automatically, you could have trouble breathing on your own, your heart could have problems, even your thought process, movement, and digestion could malfunction. Which could cause a multitude of complications.

It destroys animal habitats and causes topsoil to erode- deforestation 2) pollutes groundwater with dangerous chemicals- injecting fracking fluids into the ground 3) harms aquatic creatures and vegetation- oil spills during transport on a ship.
What is fracking fluids?In order to enhance the amount of hydrocarbons that may be extracted, drilling operations use fracking fluid (also known as frac fluid). The fluid stops the well from corroding. Among other things, it prevents blockages, bacteria from growing, and lubricates the extraction process.
In summary, the chemical composition varies from well to well and is complicated. Depending on the exposure amount, several of these substances can be dangerous to human health.
According to estimates from the oil and gas sector, chemical additives only make up about 1%.
Therefore, It destroys animal habitats and causes topsoil to erode- deforestation 2) pollutes groundwater with dangerous chemicals- injecting fracking fluids into the ground 3) harms aquatic creatures and vegetation- oil spills during transport on a ship.

2.) State the relationship between photosynthesis and cellular respiration.
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

When did the Paleozoic Era begin?
66 million years ago
400 million years ago
4 billion years ago
550 million years ago
The Paleozoic Era began approximately 550 million years ago and ended approximately 252 million years ago.
What is Paleozoic Era?The Paleozoic Era is a geological epoch that lasted about 541 million years and ended about 252 million years ago.
It is also known as the "Age of Invertebrates" because it witnessed the rise and dominance of numerous invertebrate groups, including trilobites, brachiopods, and ammonites.
From oldest to youngest, the Paleozoic Era is divided into six periods: the Cambrian, Ordovician, Silurian, Devonian, Carboniferous, and Permian.
Many significant events in the evolution of life on Earth occurred during this time period, including the Cambrian period's explosion of diversity, plant and animal colonization of land, and the emergence of reptiles and insects.
Thus, the answer is 550 million years ago.

What is the difference between a haploid, diploid, and zygote?
Answer:
[tex]\color{Blue}\huge\boxed{Answer} [/tex]
Haploid" refers to any cell that has 23 chromosomes (half of the total 46). "Gametes" are specifically sex cells that have 23 chromosomes. "Diploid" refers to any cell that has all 46 chromosomes. "Zygote" is the result of two gamete (haploid) cells fusing, and becoming a diploid cell.
Haploid means n, Diploid means 2n, while zygote is the fusion of two gametes that possess a nature of 2n.
What do you mean by Gametes?A Gamete may be defined as a cell containing only one set of dissimilar chromosomes, or half the genetic material necessary to form a complete organism.
Haploid is the quality of a cell or organism having a single set of chromosomes. A Diploid is a cell or organism that has paired chromosomes, one from each parent. In the case of humans, the haploid number is equal to 23, while the diploid number is equal to 46. A zygote is the fusion of two gametes that possess a nature of 2n, which is equal to 46.
Therefore, Haploid means n, Diploid means 2n, while zygote is the fusion of two gametes that possess a nature of 2n.

(b) Identify the dependent variable in the experiments. Identify a control group missing from the second experiment. Justify the need for this control group in the second experiment.
Hello. You have not submitted the experiments to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
A dependent variable is one that is influenced by an element, in order to present a result, that is, it is a variable that does not establish itself, being dependent on another variable to establish itself. An example of a dependent variable can be seen in an experiment that seeks to determine the differences in growth rates of bean plants that were fertilized with different organic fertilizers. As you can see, this is an experiment where the different organic fertilizers influence differences in the growth rate of bean plants. Thus, the growth of these plants depends on the fertilizer, this growth being the variable dependent on the experiment.
A control group, in turn, is an element of the experiment that does not receive the element that is being tested in the same experiment. The control group is important, because it allows the researcher to see the results of a system where the tested element does not exist, thus being able to determine the real differences that the tested element is capable of causing. Using the same example presented in the paragraph above, we can see that the different organic fertilizers are the elements tested in the experiment. These fertilizers will be applied to the plants, however it is important that at least one of these plants does not receive any fertilizer, so that the difference between a system with fertilizer and a system without fertilizer can be evaluated. This plant that received no fertilizer is the control group.
