what is the center of the DNA strand?

Answers

Answer 1

Answer:

It exhibits traits and metabolic instructions of the cell.

Explanation:

A DNA strand is a thin long molecule, with an average width of just around two nanometers. The remarkable thinness of the DNA strands allows them to be bundled very tightly fitted inside cells. Once DNA has been replicated adequately during the process of cell division, it is further wrapped together under a mechanism known as supercoiling. A non-condensed DNA is further condensed during supercoiling using a special protein known as a histone. A part of DNA packed around a large cluster of histones is called a nucleosome. Additional condensation leads to a chromosome or the most compact type of DNA that fits into the nucleus. It is also worth noting that this wrapping does not merely align DNA into a cell, but serves other objectives such as protecting DNA, thus ensuring metabolic instructions to the cell.

Instructions on how to control your cells are contained in what part of the DNA?
A. Pentose Sugar
B. Phosphate group
Hydrogen bonds
D. Nucleotide bases

Answers

Answer:

D. Nucleotide bases

Explanation:

Hope it helps.

Nucleotide bases of the DNA contain the instructions on how to control cells.

How does DNA control cells?The hundreds of distinct types of proteins that are produced by cells are coded by the nucleotide sequences that make up DNA. These proteins control and regulate cell development, division, communication with other cells, and the majority of other cellular functions. This is the reason why nucleotide sequences found in DNA are referred to as carrying or storing information.

Protein synthesis:

The sequences must first be "decoded," and the protein must then be translated. It is known as protein synthesis.

Transcription (first stage of protein synthesis): The process of copying information from a strand of DNA into a messenger RNA (mRNA) molecule is called transcription. DNA preserves genetic material as a reference or template safely and permanently in the cell nuclei.Translation (second stage of protein synthesis): The process of translation converts the information carried by messenger RNA from DNA into a string of amino acids. Essentially, it involves translating a code (nucleotide sequence) into another code (amino acid sequence).

In the product 6O2, what does the coefficient mean? There are 12 molecules of O2, There are 8 molecules of O2, There are 6 molecules of O2. There are 2 molecules of O2.

Answers

There are 6 molecules of O2.



"O2" is the formula for one molecule oxygen, which has 2 atoms.

The subscript (small) "2" tells you how many atoms are in the molecule.

The coefficient is the big number tells you the number of molecules.

In 6O2, there are 12 atoms in total (6 molecules of 2 atoms each).

In the product 6O2, there are 6 molecules of O2.

WHAT COEFFICIENT MEANS:

Coefficient, in chemistry, refers to the number behind an element. It represents the number of molecules of that element.

The coefficient tells us the amount of molecules contained in an element. For example;

In the product 6O2, this tells us that there are 6 molecules of oxygen gas (O2).

Ash trees are being removed when they show signs of the ash borer, a parasite that affects only ash trees and kills them off. What best explains why the ash trees are being cut down? The ash borer is a density-independent limiting factor, and humans need to clear cut to control tree density. The ash borer is a density-dependent limiting factor and will start to spread to nearby healthy trees. Ash trees are outcompeting other trees and are thus more affected by the ash borer. Changes in climate have decreased ash borer populations which indirectly increased the need for cutting down the trees.

Answers

Answer:

The ash borer is a density-dependent limiting factor and will start to spread to nearby healthy trees.

Explanation:

Ash borer is a parasite that affects ash trees it is highly destructive and invasive. It affects it Native host causing serious damages. Infected plant is cut down to avoid its spread to other healthy plant this is because ash bored when not control can destroy a whole population of ash trees in it Native environment within the space of 10 years. Its population dependent and would keep increasing in population and become more destructive. Thus, to avoid its spread infected trees are treated cut down and cut down.

Answer:

Explanation:

Biology, chemistry, and geology are the fields of science that provide evidence for evolution, hence option D is correct.

What is the evidence of evolution?

The uniformity of the fossil sequence from ancient to modern is possibly the strongest fossil evidence for evolution.

Fossils are a reflection of evolution and geological change due to their global distribution of organisms and distinctive traits of island species. The existence of species that are related to modern species but are now extinct is documented through fossils.

It is the series of slow, irreversible changes that occurred in early creatures over millions of years to give rise to new species we know today. Errors in DNA copying and sexual reproduction are mostly to blame for variations that led to the emergence of new species.

Therefore, biology, chemistry, and geology are the fields of science that provide evidence for evolution.
