Answer:

biology, chemistry, and geology

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.

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).

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.

Answer:

In the process of respiration, energy is released from glucose molecules and stored in smaller ATP molecules.

Explanation:

Among carbohydrates, protein and fat, carbohydrates are metabolized first on respiration.  

Glucose first breaks into pyruvic acid (Glycolysis) Pyruvic acid forms acetyl coA (Link reaction)  Acetyl coA enters into the kreb cycle, where ATP is formed.  ATP formed through substrate level phosphorylation (direct ATP) and Electron transport chain (indirect ATP). NADH2 and FADH2 formed during respiration enters into ETC where they form ATP through oxidative phosphorylation.

what is the center of the DNA strand?

Answers

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.

The correct answer is - option C.

Explanation:

A longitudinal wave with higher vitality have more noteworthy plentifulness. Abundancy is the separation between the covering and trough of the wave. The crust is the topmost layer of the wave while trough is present at the bottom portion of the wave.

In the event that the separation among crust and trough of the wave is higher so the amplitude is likewise more prominent and we can say that the wave contains a high measure of vitality and the other way around. The state of the structure of the wave simply like a hill.
