Answer:
Phagocytosis is the process of introducing larger particles into a larger cell. The process takes place by twisting the cell membrane of the "host" and enveloping the particles with a phagocytic bubble. Leukocytes use phagocytosis to take in and incapacitate bacteria that enter our body, so phagocytosis plays an important role in the immune system, as it prevents harmful cells from affecting humans.
Answer:

How is the nitrogen cycle important to humans?
A.It produces free nitrogen that humans can breathe.
B.It converts nitrogen into a form that humans can obtain by eating other organisms.
C. It produces nitrogen compounds that humans can breathe.
D. It converts nitrogen into a form that humans can obtain by absorbing it through their skin.
Answers
The nitrogen cycle is important to humans in the following way: it converts nitrogen into a form that humans can obtain by eating other organisms (option B).
What is the nitrogen cycle?Nitrogen cycle is the natural circulation of nitrogen in a series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
During the nitrogen cycle, atmospheric nitrogen is converted to nitrogen oxides by lightning and deposited in the soil by rain, where it is assimilated by plants and either eaten by animals (and returned as faeces) or decomposed back to elemental nitrogen by bacteria.
The usable form of nitrogen that is assimilated by plants becomes accessible to humans when they consume the plants, hence, depicting the importance of the nitrogen cycle.

hypothesis on what is the effect of the genes of the parental mice on the fur color of the offspring mice? use "If...then...format
Answers
Answer:
If the GENES of the parental mice encodes for a black fur, THEN the FUR COLOR of one of the offspring mice will be black.
Explanation:
Hypothesis is one of the steps used in the scientific method. It is a testable explanation of a given question or observation. Hypothesis in an experiment must be subjected to testing via experimentation in order to determine whether to reject it or not.
Hypothesis is usually constructed in the IF, THEN format. It tells us how the independent variable (cause) affects the dependent variable (outcome). In this case, a question is asked this: "what is the effect of the genes of the parental mice on the fur color of the offspring mice?"
A possible hypothesis will be: If the GENES of the parental mice encodes a black fur, THEN the FUR COLOR of one of the offspring mice will be black.
Answer:
A. If either parent mouse passes a dominant allele, the offspring will have black fur.
Explanation:
Either option is correct because it didn't show any green check. It determines on what hypothesis you wrote. I chose A because it relates to my statement. <33

describe the effects on surface area of potato of cutting the potato sticks into eight pieces
Answers
The effects of cutting the potato sticks into eight pieces would increase the surface area of the potato, and having more surface area means more area for enzymes to interact with the potato so it can be cooked easily.
What is the significance of the increased surface area of the potato?When the potato is cut into eight pieces, the surface area increases, and as the surface area increases, the cooking time decreases because the enzymes are exposed and can be deactivated when exposed to heat. So vegetables are cut before cooking.
Hence, effects of cutting the potato sticks into eight pieces would increase the surface area of the potato, and having more surface area means more area for enzymes to interact with the potato so it can be cooked easily.

The Chi-square value is zero if there is no difference between the actual and anticipated data. The Chi-square value will rise with increasing disparity.
What is the meaning of chi-square test?Chi-square tests allow us to compare observed and expected frequencies objectively because it is not always feasible to tell whether they are "different enough" to be regarded as statistically significant merely by looking at them.
The Chi-square value is a single number that adds all all the variations between the data we actually have and the data we would expect if there were no variations. If there is no discrepancy between the actual and expected data, the Chi-square value is 0. A greater difference will result in a greater Chi-square value.
Using a statistical test called the chi-square, one can compare actual findings with predictions. This test's objective is to establish whether a discrepancy between actual and expected data is the result of chance, or if the variables under consideration are related, in some way.
Therefore, the correct answer is option a. 2.

the scottish fold is a breed of cat with a mutation in a gene involved in cartilage development. the result is that each ear of the cat has a crease, so the ears fall forward and lie against the head instead of standing up like the ears of most small cats. the mutation is a dominant allele.
a cat that is heterozygous for the fold allele mates with a cat that is homozygous for the fold allele.
what are the expected percents of offspring that will have each characteristic?
Answers
The expected percent of offspring of the Scottish fold with folded ears is 75%.
How to determine offspring?The Scottish Fold is a breed of domestic cat with a natural dominant gene mutation that affects cartilage throughout the body, causing the ears to "fold", bending forward and down towards the front of the head, which gives the cat what is often described as an "owl-like" appearance.
The fold is inherited as an autosomal dominant trait. This means that a cat with folded ears may have either one (heterozygous) or two copies (homozygous) of the dominant fold gene (Fd). A cat with normal ears should have two copies of the normal gene (fd).
If a cat that is heterozygous for the fold allele mates with a cat that is homozygous for the fold allele, the expected percent of offspring that will have each characteristic are:
25% will be homozygous for the fold allele and will have folded ears.50% will be heterozygous for the fold allele and will have folded ears.25% will be homozygous for the normal allele and will have normal ears.Therefore, the expected percent of offspring with folded ears is 75%.

Why can't blizzards cause secondary succession?
Answers
Secondary succession follows a major disturbance, such as a fire or a flood. The stages of secondary succession are similar to those of primary succession; however, primary succession always begins on a barren surface, whereas secondary succession begins in environments that already possess soil.
If I had to guess I would say because blizzards happen in the winter and things don't grow in the winter, therefore secondary succession cannot happen as recolonization with plants cannot happen because most plants don't grow in the winter.
Last semester I learned about succession so I'm basing my answer on the stuff I learned.
