Which pair is correct?
a. G2 phase, preparation for mitosis
b. G1 phase, DNA replication
c. M phase, cell growth
d. S phase, cell division

Answers

i think the answers A. G2 phase preparation for mitosis

A pair that is correct with respect to the cell cycle is the G2 phase, preparation for mitosis.

What do you mean by Cell cycle?

The Cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next.

In the G1 phase of the cell cycle, the cell grows in size and synthesizes mRNA as well as proteins which are required for DNA synthesis.

M-phase governs the nuclear division (Karyokinesis), and cytoplasm division ( cytokinesis).

S-phase is known to double the amount of genetic content within the cell.

Therefore, a pair that is correct with respect to the cell cycle is the G2 phase, preparation for mitosis.

explain how the geologist knows that the flow is older then the intrusion

Answers

Through dating a sample of that rock, we determined the extrusion to be 250 million years old. An intrusion extends from the bottom layer into the fourth oldest layer. Through dating a sample of that rock, we determined the intrusion to be 100 million years old. The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.

In what cell phase(s) does chromosome production (replication) and formation (condensing) occur?

Answers

It occurs in the first phase known as the Prophase. During this the chromosomes inside the cell’s nucleus condense to form tight structures.

Spontaneous generation, the claim that living things can come from nonliving things, was an integral part of the theory of how life began and evolved for many years. In the 1600s, Francesco Redi was the first scientist to try to disprove spontaneous generation. Louis Pasteur, in 1859, finally disproved this claim with scientific evidence.

Answers

The strangler fig plant shows an aggressive growth habit as an adaptation that allowed its growth. It drops to the forest floor and develops its seeds by exposure to sunlight. Thus, option A is correct.

What are adaptations?

Adaptations are a crucial part of the evolutionary process that allows the organism to fit and survive in altered environmental conditions. It has been due to the process of natural selection that gets inherited.

The aggressive growth habit of the strangler fig vine is to ensure its survival in the rainforest covered in canopies. The seed of the plants uses sunlight and nutrients to grow at a faster rate and hangs their roots on the first floor. The sunlight increases its rate of germination.

Therefore, option A. sunlight is used for germinating the fig seeds.

The structure that the virus can use inside a host cell to produce new virus particles is the DNA.

Bacteriophage which literally means bacteria eater is a type of virus that has the ability to infect bacteria.

Basically all bacteriophages consist of nucleic acid molecule (DNA) which is surrounded by a protein coat( the capsid head).

It also possess a tail sheath through which it transfers it's DNA into host cell.

Eventually, new bacteriophages assemble and burst out of the bacterium in a process called lysis.

44. What are the 3 polymers for nucleic acids.________________________________________
45. What are the 2 main functions for nucleic acids.________________________________________________________________________

Answers

Answer:

42. Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine

Explanation:

43.Nucleic acids contain the same elements as proteins: carbon, hydrogen, oxygen, nitrogen; plus phosphorous (C, H, O, N, and P). Nucleic acids are very large macromolecules composed of repetitive units of the same building blocks, nucleotides, similar to a pearl necklace made of many pearls.

The brain and spinal cord make up the central nervous system. The brain directs our thoughts, memories, movements, and emotions. Between the brain and the nerves that run throughout the body, the spinal cord relays messages.

It regulates cognition, personality, memory, emotion, speech, and the capacity to feel and move. The corpus callosum, a band of nerve fibers in the middle of the brain, connects the left and right hemispheres of the brain.

what are 5 functions of carbohydrates

Answers

☁️ Answer ☁️

PROVIDES INSTANT ENERGY TO THE BODY:

This appears to be the primary function of carbohydrates in the body.

Carbohydrates which we consume as food in the form of starch (ex: potato, bread), sucrose (ex: sugar, fruits), etc. get digested in the body to release glucose.

RESERVE FOOD:

Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.

CARBOHYDRATES FORM OTHER BIOMOLECULES:

Carbohydrates in excess are converted into other bio-molecules of physiological importance. They mostly get stored in the form of fats.

DETOXIFICATION OF THE BODY BY METABOLISM:

Many drugs and toxic wastes in the body are metabolized for easy excretion in the body.

SPARING PROTEIN

In a situation where there is not enough glucose to meet the body’s needs, glucose is made from amino acids. Because there is no storage molecule of amino acids, this process requires the destruction of proteins, primarily from muscle tissue. The presence of adequate glucose basically spares the breakdown of proteins from being used to make glucose needed by the body.

Electrons in atoms are arranged in energy levels. The electrons in the energy levels of carbon are;

n= 1 ------ 2 electrons

n = 2 ----- 4 electrons

n =3 ----- 0 electrons

n = 4 ----- 0 electrons

Carbon has the electronic configuration; 1s2 2s2 2p2.

This means that there are only two electrons in the n-1 level and there are four electrons in the n=2 level.

This makes a total of six electrons in carbon as shown.
