2. Why is it important that DNA is replicated prior to cell division?
3. How are normal cells and cancer cells different from each other?
4. Describe mistakes that can occur during the cell cycle and cause human disorders.

Answers

Answer 1

Mitosis aims to create daughter cells that are completely genetically similar to their mothers, with no extra or less chromosomes. In contrast, meiosis serves a single function in the human body that is the creation of gametes.

What is cell division?

The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle.

Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.

Grow in the absence of signals instructing them to do so in cancer cells. Only when they get such signals do normal cells expand. Disregard cues that would typically instruct cells to cease dividing or die.

Aneuploidy is a condition when there are either too many or too few chromosomes in the daughter cells produced during mitosis.

Thus, this is the overall purpose of mitosis and meiosis.

Answer 2

1. The overarching goal of mitosis is to ensure cell division and the transfer of genetic material to daughter cells for tissue repair, growth and development.

2. To maintain genetic integrity, DNA replication is necessary prior to cell division.

3. Cancer cells have uncontrolled growth, escape cell death and lack contact inhibition, whereas normal cells have controlled cell division, experience programmed cell death and show contact inhibition.

4. The disorders in humans can result from errors in the cell cycle. Diseases such as Down syndrome are caused by abnormal chromosomes. Gene changes can affect the development of cancer.

Meiosis produces gametes for sexual reproduction, while mitosis assures cell division for growth, development, and tissue repair. Accurate transmission of genetic information and preservation of genetic integrity in daughter cells depend on DNA replication prior to cell division.

Whereas cancer cells have uncontrolled proliferation, escape from cell death, and lack contact inhibition, normal cells have regulated division, programmed cell death, and appear to have contact inhibition. Human disorders such as chromosomal abnormalities (such as Down syndrome), gene mutations that cause cancer, errors in DNA replication or repair that cause genetic disorders, and cell cycle control that leads to uncontrolled cell division and tumor formation, all of which Mistakes made during this can have consequences. cell cycle.

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.

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

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.

En un cruce entre peces naranjas y peces grises se obtiene una generación (f1) de 50% peces grises . Realice el cruce y explique lo ocurrido dato: el color naranja es dominante sobre el color gris

Answers

Answer:

Uno de los progenitores es heterocigoto para color naranja (Nn) y el otro parental es homocigoto recesivo para gris (nn). Al haber una cruza entre un homocigoto recesivo y un heterocigoto, la 50% de la progenie expresa color naranja (Nn), mientras que el otro 50% expresa color gris (nn).

Explanation:

Datos disponibles:

Cruce entre peces naranjas y peces grises50% de la F1 son peces grisesNaranja dominante sobre gris

Podemos nombrar el alelo dominante para color naranja N, y al alelo recesivo  para color gris n.

Para que en un cruce entre dos fenotipos distintos, el 50% de la primer camada exprese uno de estos fenotipos, entonces uno de los parentales debe ser heterocigoto, mientras que el otro parental debe ser homocigoto recesivo. De esta forma 50% de la primera generación expresara uno de los fenotipos, mientras que el otro 50% expresará el otro fenotipo.

Supongamos que uno de los parentales lleva el genotipo Nn, y el otro parental es nn.

Cruce:

substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.

Answer:substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.

Explanation:Enzymes and substrates share specificity in that an enzyme will only react with a specific substrate • This is because the active site is complementary in both shape and charge to a given substrate • The model by which this is known is ‘lock and key’ as the substrate is a precise structural fit for the enzyme, much like a lock and key • When the enzyme and substrate bind, they form an enzyme-substrate complex, before the substrate is catalytically converted into a product

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.

How does genetic variation allow humans to survive long-term?
Which type of reproduction is responsible for genetic variation?

Answers

Answer:

Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population. Sexual reproduction promotes genetic variation by producing different gene combinations. Meiosis is the process by which sex cells or gametes are created. Genetic variation occurs as alleles in gametes are separated and randomly united upon fertilization.

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.
