List the 3 reasons why mitosis occurs
Mitosis is a cell division method a part of the cell cycle that is essential for growth and development, repair and replacement, and asexual reproduction.
What is mitosis?Mitosis is a type of cell division method that occurs in all the somatic cells and plays a crucial role in living organisms. They produce daughter cells to increase the cell number and to aid in the growth and development.
They replace and repair the damaged cells in the body and also is a form of asexual reproduction where the parent cell is divided to form a new daughter cell with the same ploidy.
Therefore, mitosis is essential for growth, repair, and asexual reproduction.

Answer:
Explanation:
This shows that in 2018 the number of nests increased while the number of eggs per nest increased at the minimum and decreased at the maximum when compared to 1780. We can see that by looking at the graph. The blue curve represents 2018 and the dotted 1780. The Y-axis represents the number of nests while the X-axis represents the number of eggs. The dotted one is shorter but wider and the blue one is taller.
Describe the fungi reproduction process.
Please I really need this answer ASAP.
Fungi reproduce asexually by fragmentation, budding, or producing spores. Fragments of hyphae can grow new colonies. Mycelial fragmentation occurs when a fungal mycelium separates into pieces with each component growing into a separate mycelium. There are many types of asexual spores.
Answer:
hello!
Explanation:
Following a period of intensive growth, fungi enter a reproductive phase by forming and releasing vast quantities of spores. Spores are usually single cells produced by fragmentation of the mycelium or within specialized structures (sporangia, gametangia, sporophores, etc.). Spores may be produced either directly by asexual methods or indirectly by sexual reproduction. Sexual reproduction in fungi, as in other living organisms, involves the fusion of two nuclei that are brought together when two sex cells (gametes) unite. Asexual reproduction, which is simpler and more direct, may be accomplished by various methods.
Asexual reproduction
Typically in asexual reproduction, a single individual gives rise to a genetic duplicate of the progenitor without a genetic contribution from another individual. Perhaps the simplest method of reproduction of fungi is by fragmentation of the thallus, the body of a fungus. Some yeasts, which are single-celled fungi, reproduce by simple cell division, or fission, in which one cell undergoes nuclear division and splits into two daughter cells; after some growth, these cells divide, and eventually a population of cells forms. In filamentous fungi the mycelium may fragment into a number of segments, each of which is capable of growing into a new individual. In the laboratory, fungi are commonly propagated on a layer of solid nutrient agar inoculated either with spores or with fragments of mycelium.
Budding, which is another method of asexual reproduction, occurs in most yeasts and in some filamentous fungi. In this process, a bud develops on the surface of either the yeast cell or the hypha, with the cytoplasm of the bud being continuous with that of the parent cell. The nucleus of the parent cell then divides; one of the daughter nuclei migrates into the bud, and the other remains in the parent cell. The parent cell is capable of producing many buds over its surface by continuous synthesis of cytoplasm and repeated nuclear divisions. After a bud develops to a certain point and even before it is severed from the parent cell, it is itself capable of budding by the same process. In this way, a chain of cells may be produced. Eventually, the individual buds pinch off the parent cell and become individual yeast cells. Buds that are pinched off a hypha of a filamentous fungus behave as spores; that is, they germinate, each giving rise to a structure called a germ tube, which develops into a new hypha.
Although fragmentation, fission, and budding are methods of asexual reproduction in a number of fungi, the majority reproduce asexually by the formation of spores. Spores that are produced asexually are often termed mitospores, and such spores are produced in a variety of ways.
What is the charge of the outside of the DNA molecule?
Answer:
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

An invasive top predator such as boa constrictors not necessary eat animals in the tertiary trophic level, however they affect them because they eat their food. Boa constrictors' diet include a wide variety of animals, including birds, mammals, and other reptiles
Suppose a scientist is doing an experiment to determine the effect of an all-organic diet on the occurrence of
cancer in rats. Which of the following would be the best control group for this experiment?
A. Rats fed a standard rat diet (not organic)
B. Rats fed an all-organic diet
C. Pats fed an all-organic diet, but half the amount of normal
D. Rats that are not fed anything
Hmm... I'm not 100% sure but I'd say it was D.
Rats fed a standard rat diet (not organic) will be the best control group for this experiment. The correct option is A.
What is control group?A control group in a scientific experiment is a group that is isolated from the rest of the laboratory activity and where the regression analysis being evaluated cannot influence the outcomes.
This isolates the independent variable's effects on the experiment and can help rule out other explanations for the experimental results.
An experimental group is made up of participants who have their independent variable manipulated in some way. These are the people who receive special treatment.
The best control group for this experiment will be rats fed a standard rat diet (not organic).

1. During mitosis, a single cell divides to produce two daughter cells. What must happen in the original cell so that each of the daughter cells has a complete set of chromosomes?
Mitosis is the cell division which occurs in all types of cells in the body. This results into formation of daughter cells with same set of genetic material as the parent cell.
What is Mitosis?
Mitosis is a type of cell division which occurs in all types of cells. This division is also called as Equational division as the genetic content remains constant from the parents to offspring. This process results into formation of two daughter cells which are similar to the parent cell.
In mitosis, a cell divides to form two identical daughter cells with same genetic material. It is important that the daughter cells have a copy of every chromosome in their nucleuc, so the process involves copying of the chromosomes first and then carefully separating the chromosomes copies to give each new cell a full set of genetic material.

( please, do not comment if you do not know the answer, I will give Brianlist ) Please complete the following:
1. You and Tim, who is larger than you are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull
it, you accelerate until you reach a comfortable velocity. Then you stop and switch places with Tim. Tim now pulls you in the wagon, accelerating
from a stop to a comfortable velocity. Now, Tim may be bigger than you, but you have been working out and are just as strong as Tim, so the force
that Tim uses to pull the wagon is the same force that you used. You both pull with the exact same amount of force. Who was riding in the wagon
when it had the greatest acceleration during start up? Why? Use Newton's second law to explain.
2. Now Sara comes along, and she is the exact same size as you. However, she is even stronger than you! When she pulls you in the wagon, she pulls
with a greater force than when you pull her. Now who is in the wagon when it has the greatest acceleration? Explain, using Newton's second law.
Answer:
2. Sarah
Explanation:
because she is stronger, she is able to pull faster and easier because of the amount of weight she can carry vs the amount of weight you can carry. Although you are the same height, she has more muscle.
