Why is it necessary for the cell to grow and duplicate its DNA before the start of meiosis?

Answers

Answer 1

Answer:

Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis. Since the cell is dividing it needs two copies of its DNA - one is kept by the parent cell and the other is passed to the daughter cell. ... So this process of duplicating DNA is very important.

Answer:

Explanation:

Marine phytoplanktons are not found at great depths in the ocean because of the lack of sunlight at these depths.

Phytoplanktons need sunlight to survive. They utilize light for food production through photosynthesis. Without light, this process would become limited and the phytoplanktons will die of starvation.

At great ocean depths, sunlight penetration becomes limited and thus, phytoplanktons also stay away from these depths.

Blood sugar regulation is an important part of normal body function. Imbalance of the process
due to Type 1 or Type 2 Diabetes can be life threatening. In a paragraph give a detailed
description of how normal body function keeps this process in homeostasis. You must use and
underline the following vocabulary words/phrases in your paragraph: homeostatic/normal blood
sugar level, pancreas, liver, blood sugar level drops, blood sugar level rises, insulin, glucagon,
liver stores glucose as glycogen, liver releases glucose by breaking down glycogen. Many of
the words/phrases will need to be used more than one time.

Answers

Answer:

Blood sugar regulation process is an important part of the body to maintain homeostasis.

Explanation:

For normal function of the body, the blood sugar must be in normal range to keep the body in homeostasis. If a person blood sugar level rises, insulin hormones secreted by pancreas in order to decrease blood sugar in the blood by storing glucose in the liver in the form of glycogen while on the other hand, if the blood sugar level drops then the glucagon secreted by pancreas in order to increase blood glucose level by conversion of glycogen into glucose present in the liver.

1. How does base pairing differ in RNA, compared to DNA?

A: A pairs with U
B: T pairs with U
C: U pairs with G
D: U pairs with C

Answers

Answer:

A. A pairs with U

Explanation:

In DNA, the nitrogenous bases are A, T, G, and C. In RNA, the nitrogenous bases are A, U, G, and C.

A pairs with U in RNA because it requires less energy to use uracil over thymine.

Hope that helps.

The base pairing in RNA is different from DNA as A pairs with U.

What is DNA?

DNA exists abbreviation of deoxyribonucleic acid, an organic chemical of complex molecular structure that exists found in all prokaryotic and eukaryotic cells and numerous viruses. DNA codes genetic information for the information of inherited traits. Each strand of a DNA molecule exists comprised of a long chain of monomer nucleotides. The nucleotides of DNA consist of a deoxyribose sugar molecule to which stands connected a phosphate group and one of four nitrogenous bases.

Hence, The base pairing in RNA is different from DNA as A pairs with U.

Therefore, the (A) option exists as the correct answer.

True or false: Guard cells close openings in the leaves slowing down water loss.

Answers

Answer:

True

Guard cells close openings in the leaves slowing down water loss.

Answer:

True

Explanation:

Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease. So when it is opened the water vapor depletes quicker but when its closed it slows down the process of depletion.

The statement, "the total mass of the product must equal the total mass of the reactants" is known as the ____

Answers

Answer:

The statement, "the total mass of the product must equal the total mass of the reactants" is known as the Law of conservation of mass.

Explanation:

Law of conservation of mass:

According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.

This law was given by French chemist  Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.

Consider the example of photosynthesis reaction:

6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂

There are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.

Why might there be a competitive advantage to having a different flight initiation distance

when a bird is incubating eggs

Answers

Answer: The birds can perceive any kind of danger which can harm the eggs after laying.

Explanation:

The birds show response towards the other stimulus around them like weather conditions like excessive heat and rain and predators. Also they can sense the danger of damage to eggs by fellow members of the species. The distance at which the birds fly from the danger is the flight initiation distance. It is the separation distance from any kind of danger or disturbance and birds cross this distance before incubating their eggs. This is an competitive advantage with that of other members of the species as the bird will able to give birth to new ones and its population will increase in number, so the chances of reproduction and survival increases in this case.
