Answer:

C

Explanation:

Everything else has to do with growth but C is talking about food/energy.

A plant using sunlight to make its own foods is accomplished by repeated cell division.

Cell division is the process by which a parent cell divides into two daughter cells. Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome before dividing.

There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.

In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.

Answer:

movement of chemicals into the dendrites of the neuron

Explanation:

Nerve impulse occurs when electrical gradient is moved across the plasma membrane of a resting neuron this is done when the neuron receives a chemical signal from another cell or some other type of stimulus. This action potential then travels down the neuron’s axon as an electric current.

Resting potential occurs because of the difference in electrical charge across the plasma membrane of a neuron.

An electrical gradient is maintained by the sodium-potassium pump this is done across the plasma membrane of a neuron when it is not transmitting a nerve impulse this is the resting potential of the neuron.

1 .Electrophoresis is a laboratory technique used to separate DNA, RNA, or protein molecules based on their size and electrical charge.

2.Gel electrophoresis is a technique used to separate DNA fragments (or other macromolecules, such as RNA and proteins) based on their size and charge.

... [All DNA molecules have the same amount of charge per mass. Because of this, gel electrophoresis of DNA fragments separates them based on size only.]

3.Gel electrophoresis [ pls chck tiz answer!]

4.DNA is negatively charged, therefore, when an electric current is applied to the gel, DNA will migrate towards the positively charged electrode. Shorter strands of DNA move more quickly through the gel than longer strands resulting in the fragments being arranged in order of size.

5.A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable.

High-quality buffers are an important part of electrophoresis. They allow a current to be carried through the sample while resisting pH changes in the overall solution.

Answer:

Deletion of a DNA base from a gene affects an organism by changing the sequence of amino acids in a protein.

Explanation:

A DNA fragment forms a gene, with a specific sequence of nitrogenous bases, which determines the synthesis of a specific protein. When a deletion of a base occurs in such a gene, it affects:

In summary, the deletion of a base in the DNA will affect the protein to be synthesized by changing the amino acid sequence of its structure.

The other options are not possible, because the deletion of a base in the DNA of a gene

    Does not influence the number of chromosomes that the gametes will have.

    It does not produce long chains in the chromosomes.

    It does not affect the ribose structure of the nucleic acids.

Deletion of a DNA base from a gene affects an organism by :

B) Changing the sequence of amino acids in a protein.

Deletion of a DNA base from a gene affects an organism by the changing the sequence of amino acids in a protein.

A DNA part shapes a quality, with a particular arrangement of nitrogenous bases, which decides the blend of a particular protein. When a erasure of a base happens in such a quality.

Transcription of the mRNA, which is able have the arrangement of changed bases.

it reduced the risk of cancer

Answer:

true

Explanation:

please mark me brainliest

DNA replication results in two identical daughter molecules each consisting of one old (original) strand and one newly-synthesized strand. Therefore, it is true.

The process of duplicating the parent DNA helix into two identical daughter helices is known as DNA replication. One parent strand is passed down to each daughter strand in this semi-conservative procedure.

In prokaryotic cells, DNA replication takes place in the nucleoid area, whereas it happens in the nucleus in eukaryotic cells. Prior to cell division, DNA replication takes place in the S phase of the cell cycle.

Replication fork pairs that form at the origins of replication and then move in opposition to one another carryout genome duplication. When convergent replication forks meet, DNA replication is complete. Hence, it is true.

Glycolosis has a net gain of 2 atp

Explanation:

It produces 4 but you invest 2 to start so its only net gain of 2

You also ge 2 pyruvate and 2 NADH

Two pyruvate molecules, two ATP molecules, and two NADH molecules are the substances produced in the process of glycolysis.

These substances are gained from glucose in order to generate energy which is needed in different activities of the cell. ATP is the molecule which is used by the cell for doing activities which needs energy.

Both pyruvate and NADH molecules are also converted into ATP molecules in the end and used by the cell so we can conclude that in the process of glycolysis, two pyruvate, two ATP, and two NADH molecules are formed.

Answer:

During both mitosis and meiosis, DNA replicates first during S phase of interphase. Each copy (DNA molecule) is called chromatid. Before anaphase they remain together, joined by the centromere in the chromosome.

Part 1: How many chromatids and chromosomes are present at:

(a) anaphase of mitosis: During this phase sister chromatids split. We would have 48 chromosomes in each pole and 48 chromatides.

(b) anaphase I of meiosis: During this phase homologous chromosomes split, being a reductional division. In each pole we will have half the chromosomes we had after DNA replication. This is 24 chromosomes but 48 chromatides (remember they will split during anaphase II).

(c) anaphase II of meiosis: This is an equational division, we will have 24 chromosomes in each pole and 24 chromatides. Each chromatid is considered a chromosome.

(d) G1 prior to mitosis: During this phase DNA has not replicated yet and it is not condensed either. This formed is called chromatin. We will assign one chromatid for each chromosome. This is a somatic cell, so: 48 chromosomes and 48 chromatids.

(e) G2 prior to mitosis: After S phase, we have duplicated all chromosomes. We will assign two chromatids per chromosome: this is 96 chromatides and 48 chromosomes.

(f) G1 prior to meiosis: Before DNA duplication, 48 chromosomes, 48 chromatids.

(g) Prophase of meiosis I: After DNA replication, condensation of the chromatin takes place: 48 chromosomes, 96 chromatids.

Part 2: How many chromatids or chromosomes are present in:

(h) An oogonial cell prior to S phase: This is G1 phase, 48 chromosomes.

(i) A spermatide: This is the male haploid gametid, after meiosis: 24 chromosomes and 24 chromatids.

(j) A primary oocyte arrested prior to ovulation: They are arrested at prophase I of meiosis. This means their DNA is still duplicated and chromatides have not divided yet. 48 chromosomes and 96 chromatids.

(k) A secondary oocyte arrested prior to fertilization: They are halted at metaphase II of meiosis, meaning they have half the chromosomes (24) but chromatids are still together (48).

(l) A second polar body: They suffered the same process as the mature ovum but remained with little cytoplasm. They have 24 chromosomes and 24 chromatids.

(m) A chimpanzee sperm: They have completed both meiosis as well, they have 24 chromosomes and 24 chromatids.  

Explanation:

Mitosis is a type of cell division in which the number of chromosomes in the parent cell is similar to the daughter cell. Mitosis occurs in the somatic cells.

The chromosomes present in the Chimpanzee's cell after mitosis are 48 chromosomes.

The mitosis can be explained as:

1. Mitosis is a type of cell division in which the number of chromosomes in the daughter and parent cells are similar.

2. During the DNA replication process, the DNA is duplicated and separated into the individual two daughter cells.

Thus, the cells with 48 chromosomes will give rise to daughter cells consisting of 48 chromosomes.
