The ?? reaction to photosynthesis puts carbon dioxide into the form of carbohydrates. Light or dark?

Answers

Answer 1

Answer: The question says,'the ........ reaction of photosynthesis puts carbon dioxide into the form of carboydrates. The correct option is dark reaction. During the dark reaction of photosynthesis, the ATP and the NADPH that were formed during the light reaction are used to drive the synthesis of carbondioxide from carbon molecules, thus reducing them to ADP and NADP.

There are two checkpoints during the cell cycle that regulate cell division. They are right before the _____ phase and _____ phase. S; M G1; G2 S; G1 M; G2

Answers

Two checkpoints during the cell cycle that regulate cell division are right before S phase and M phase.

Cell cycle checkpoints are control mechanisms necessary for proper cell division. In the cell cycle, there are two checkpoints: the G1 checkpoint and the G2 checkpoint. The G1 checkpoint is right before the S phase, and G2 checkpoint is right before the M phase.
If something is wrong at the G1 checkpoint, the cell will not enter the cell cycle. It is important to be delayed before cell enters S phase where DNA replication commences.
The G2 checkpoint is a DNA damage checkpoint and if DNA is damaged, entering the cell cycle is delayed before mitosis (M phase).

Answer:Sphase and Mphase

Help please! Which area pictured below shows water entering the atmosphere from respiration and transpiration

Answers

Answer:

Correct answer is Area 1.

Explanation:

Transpiration is the evaporation of water or moisture in plants. In this process, water is carried through plants to small pores of the underside of leaves from its roots.

In simple words, Respiration in plants is the process in which plants take in glucose and oxygen, release carbon dioxide and water and release energy.

So, only Area 1 showing that plant releasing water in the atmosphere in the given picture.

Area 1 shows water entering the atmosphere from respiration and transpiration, because it is the only one where water goes "up". Transpiration is the water movement through a plan, and later evaporation of water from leaves.

The two species of snakes, the Emerald Tree Boa and the Boa Constrictor, belong to the same genus; however, the former is tree dwelling and needs high humidity whereas the latter is terrestrial and requires a dry environment. What kind of the evolutionary mechanism was responsible for this?. A. Allopatric evolution. B. Sympatric evolution. C. Convergent evolution

Answers

B. Sympatric evolution. is responsible to this. It's the process of evolving species from one shared ancestor in the same geographic region.

Answer:

The kind of evolutionary mechanism responsible for both snakes is B) Sympatric Evolution.

Explanation:

We need to study two species of snakes, the Emerald Tree Bow and the Boa Constrictor, they belong to the same genus. However, the former is tree-dwelling and needs high humidity whereas the latter is terrestrial and requires a dry environment.

To explain this phenomenon we present a similar example: Imagine that your family has lived in the same house for many years. After that, imagine that your sister moves out of that house and into a house in a nearby neighborhood. She begins a new family there and, through the years, her family continues to grow and live in this new house. When your family separated, you became different groups of people from the same common ancestor. Eventually, you might even evolve enough to feel that there are more differences between you than similarities. When this happens in nature, it's called sympatric speciation. This process allows new species to evolve from a common ancestor, while the new and old species are still living in the same geographic region.

This example is almost the same as both snakes. Sympatric Evolution was responsible for this phenomenon.

Finally, we can conclude that the kind of evolutionary mechanism responsible for both snakes is B) Sympatric Evolution.

In cattle, roan coat color (mixed red and white hairs) occurs in the heterozygous (Rr) offspring of red (RR) and white (rr) homozygotes. Which of the following crosses would produce offspring in the ratio of 1 red:2 roan:1 white? A) red × white
B) roan × roan
C) white × roan
D) red × roan
E) The answer cannot be determined from the information provided.

Answers

The answer is B) roan x roan.

Let's summarize:
R - dominant allele,
r - recessive allele,
RR - dominant homozygous with red color,
rr - recessive homozygous with white color,
Rr - heterozygous with roan color.

If we cross two heterozygous (Rr):

Parents: Rr x Rr
Offspring: RR Rr Rr rr

then, the offspring will be: 1 red (RR) : 2 roan (Rr, Rr ) : 1 white (rr).

Final answer:

The cross between roan (heterozygous) cattle would produce offspring in the ratio of 1 red: 2 roan: 1 white. This is a scenario of a monohybrid cross, yielding a 1:2:1 ratio in offspring.

Explanation:

In this genetics problem, 'R' represents red coat color gene, 'r' represents white coat color gene, and the combination 'Rr' gives a roan coat color. To get a 1:2:1 ratio of red:roan:white, the cross must be between two heterozygotes, or roan-colored cattle (Rr × Rr). So, the correct option is B) roan × roan. This type of cross, known as a monohybrid cross, yields a genotypic and phenotypic ratio of 1:2:1 (1 RR: 2 Rr: 1 rr) in the offspring.

The genetic material contained in the nucleus of each of the new cells is most likely?

Answers

The answer is identical to the original body cell or it is half of the original body cell.

A cell cannot live forever so they either divide into two new cells through mitosis or die.In the process of mitosis one cell divides into two identical cells. So, a genetic material in the nucleus of each of the new cells will be identical to the original body cell.
Beside mitosis, there is meiosis. It is a cell division that results in the reduction of chromosome number by half. In this case, new cells will be haploid and there will be half less genetic material than it the original body cell.
