Why does a cell need to copy its DNA before undergoing mitosis?

Answers

Answer 1
Because existing cells need to divide to produce new cells. So the DNA needs to be copied before the cell division so that each new cell receives a full set of instructions.

Leaves of a healthy potted plant were coated with Vaseline to block stomata. Will this plant remain healthy for long? State three reasons for your answer.​

Answers

➜ If waxy coating is made on the surface of leaf, loss of water in the form of water vapour does not take place. Even the gaseous exchange will not take place. So, photosynthesis will either be reduced or will not take place.

The plant will not remain healthy for long because:

[i] Exchange of gases will not take place.

[ii] Photosynthesis will either be reduced or will not take place due to lack of CO2.

[iii] Transpiration will not take place, so there will be no mechanism of cooling in hot weather.

Compare and contrast gradualism and punctuated equilibrium. Provide at least one comparison and one difference in your answer. You may use examples for each if that helps you with answering the question.

Answers

Answer:

Gradualism and punctuated equilibrium both are the process of evolution of species over time. However, the gradualism process involves the evolution that occurred slowly, occurring in small periodic changes in the gene pool over a long period of time. Whereas Punctuated equilibrium takes place there are longer periods of apparent stasis interrupted by the sudden change.

They both help in finding the relative change in evolution rate and assist in the study of the anatomical changes occurred during the evolution in different kind of animals or organisms.

A woman and her baby are on a TV talk show to determine whether or not a particular man is the father of the child. Mom is blood type O and the baby is blood type B. The potential dad is blood type A. Is it true or false that he is the father?

Answers

Answer:

No that is not the father

Explanation:

The fathers blood would have to be type B. Type A is dominate to O and co-dominate to B so you get AB blood, type B blood is dominate to O blood. So if the mom has to be OO to show O blood and the father has to be AA blood because he isn't AB or AO, which could make the baby AO or OO blood. Since none of this is true the "TRUE" father would have to have AB, BB, or Bo blood.

What is biomass burned to produce

Answers

Answer:

Burning either fossil fuels or biomass releases carbon dioxide (CO2), a greenhouse gas. However, the plants that are the source of biomass for energy capture almost the same amount of CO2 through photosynthesis while growing as is released when biomass is burned, which can make biomass a carbon-neutral energy source.

ACCGTACTG

Given the following sequence of DNA write the correct sequence of amino acids.

ATAGGCGTA

Answers

Answer:

1. ATGGCTATT

2. UGGCAUGAC

3. mRNA: UAU-CCG-CAU, amino acids: tyrosine(tyr)-proline(pro)-histidine(his)

Explanation:

For DNA, the complementary bases are T=A and C=G. This means every time you see one of these letters, the corresponding letter goes with it. For mRNA, the bases are T=A, A=U, C=G. It is the same except now, there should be no "T" in the mRNA sequence. With amino acids, you would first code for the mRNA sequence, every three letters being the amino acid sequence. To find the amino acid, you would look at a codon chart unless your teacher wants you to memorize them.  The first three letters of the amino acid are the abbreviation.

What is Bacteria?

Bacteria are defined as ubiquitous, mostly free-living organisms that contain a single biological cell that constitute a large domain of prokaryotic microorganisms. Bacteria are a few micrometers in length that were among the first life forms to appear on Earth, and are present in most of its habitats.

Some bacteria are harmful that serve a useful purpose that support many forms of life, both plant and animal, and are used in industrial and medicinal processes. This group A mentioned in the above example of Bacteria can be pathogenic, ubiquitous in the environment whose cell walls are composed of peptidoglycan.
