Mitosis

Explanation:

Mitosis is the process of cell division. In this process cells are split to create exact replicas of eachother. It is why we don't grow ears on our hands when they are injured. The hand cells are replicated to create more, so it heals correctly. In the Mitosis the two resulting daughter cells always have the same number of chromosomes from the parent cell. Their role is to maintain the same number of chromosomes in each cell division constant, which allows us to grow and self-maintain our bodies.

Need help plz!!! Trying to catch up on biology anything can help!!!!

Answers

Answer:

See the answer below

Explanation:

The control group in an experimental study is the subject group that is not administered the treatment variable. The control group forms the baseline for comparing the effects produced by the treatment variable on the experimental group.

Thus, in this case, the control group would be the 10 mice that were not exposed to the radio waves.

The independent or the manipulated variable, in this case, is the exposure or otherwise of the mice to the radio waves.

The dependent variable is the actual variable that is going to be measured, otherwise known as the effect variable. In this case, the dependent variable would be the strength of the mice measured by their ability to push the block of wood blocking their food.

Since 8 out 10 mice and 7 out of 10 mice were able to push the wooden block in both the experimental and the control group, Bart's conclusion should reject the hypothesis that the radio waves make mice extra strong.

Bart's experiment can be improved by increasing the number of subject mice in each group. The more the number of subjects, the more the accuracy of the outcome would be.

Your lab is working on sequencing a new plasmid. Before starting, you all decide to guess how many base pairs you think the new plasmid has. The lab members' guesses are 4,005; 4,006; 4,007; and 4,010. It turns out the plasmid has 7,968 base pairs. Accurate Precise Neither Both

Answers

Solution :

In this question we have to determine whether the statement given in the question is accurate or precise or both or neither of them.

In the question it is given that the lab members are making a guess about how many base pairs will the new plasmid will have.  Their random guesses of base pairs are 4,005; 4,006; 4,007; and 4,010. But in actual, the new plasmid has 7,968 number of base pairs.

Therefore, according to it, the data in the statement is precise but it is not accurate.

Precision refers to the degree of the reproducibility of measurements even if the values varies from accepted values. And accuracy shows how much close the measurement is to the accepted or the known value.

We say that we have a precise data on our hands and not an accurate one

Option B

Accuracy

Question Parameters:

The lab members' guesses are 4,005; 4,006; 4,007; and 4,010.

Generally, accuracy shows how close a size is to a regarded or established value, whilst precision in facts capability the degree of reproducibility of the measurements. Measurements that are each specific and correct are repeatable and very close to genuine values.

Hence, we say that we have a precise data on our hands and not an accurate one

The hydrophobic effect is related to the fact that water is most stable when it has the most hydrogen bonds and that nonpolar molecules decrease the number of those bonds. True or false

Answers

Answer:

True

Explanation:

When a hydrophobe is dropped in an aqueous medium, hydrogen bonds between water molecules will be broken to make room for the hydrophobe; however, water molecules do not react with hydrophobe. This is considered an endothermic reaction, because when bonds are broken heat is put into the system. The hydrophobic effect is considered to be the major driving force for the folding of globular proteins. It results in the burial of the hydrophobic residues in the core of the protein. It is exemplified by the fact that oil and water do not mix and was described well by G. S. Hartley in 1936. 1 Hydrophobic effect. The hydrophobic effect increases the thermodynamic activity of large hydrophobic molecules of metal complexes formed in the aqueous phase of solvent extraction systems, which promotes their transfer from the aqueous to the organic phase.

In "gastrulation" cells begin to differentiate. They form different types of tissues so they can accomplish different purposes in the body.

True or False?

Answers

Answer:

The statement that says that In "gastrulation" cells begin to differentiate and they form different types of tissues so that they can accomplish different purposes in the body, is true.

Explanation:

Gastrulation involves a process of cell division, migration and differentiation, being one of the stages of embryonic development.

Cell differentiation and migration in gastrulation leads to the formation of germ layers, which are responsible for forming different tissues and fulfilling different functions in the body:

The outermost lamina is called the ectoderm, which can give rise to nerve tissue and part of the skin tissue. The mesoderm is the middle lamina, and from it vascular, bone, muscle, and joint tissue can develop, as well as tissues of excretory and reproductive organs.  Endoderm corresponds to the internal lamina, forming in great part the mucous membrane of the organs of the digestive system.

It is true, then, that In gastrulation cells begin to differentiate and form different types of tissues so they can accomplish different purposes in the body.

Some people have one sickle cell gene and one normal gene. They have few defective cells and no symptoms because the sickle cell gene is recessive. How does the human system of reproduction result in people getting one copy of a sickle cell gene and one copy of a normal gene? Describe the process.

Answers

Answer:

Through meiosis

Please find the description below

Explanation:

Humans reproduce via a type of reproduction called SEXUAL REPRODUCTION. Sexual reproduction is the type of reproduction that involves two sexes (male and female) of an organism. The males produces male gametes called SPERM while females produce female gametes called EGG.

The process by which these gametes is produced is called MEIOSIS. Meiosis is a division that reduces the chromosome number of the parent cells. According to Gregor Mendel, it occurs in such a way only one allele of a gene is present in each gamete.

Hence, according to this question, getting one copy of a sickle cell gene and one copy of a normal gene is as a result of meiotic division of male and female. One parent undergoes meiosis and contributes the normal allele (S) while the other parent undergoes meiosis and contribute the sickle allele (s).

Bunnies and coyotes. For just one level of movement on the pyramid (bunnies to coyotes - their preferred food), and the bunny weighed 5 kg, how many kg of "energy" would the coyote actually get by eating it?

Answers

Answer:

The coyote is actually getting 0.5 kg of "energy" by eating 5 kg of bunnies.

Explanation:

At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. According to the 10% rule, to support 1 kg of coyote, 10 kg of the anterior level is needed. To calculate this, we need to multiply the biomass of the coyote by 10 to get the biomass of its anterior level.

If 10 kg of the anterior level (bunnies) are needed to support 1 kg of coyote, we need to calculate how many kgs of a coyote are supported by 5 kg of bunnies.

10 kg of bunnies ------- 1 kg of coyote

5 kg of bunnies --------- X =  0.5 kg of coyote.

Answer:

The coyote is actually getting 0.5 kg of "energy" by eating 5 kg of bunnies
