Describe solution concentration outside the cell in terms of hypotonic, hypertonic and isotonic.

Answers

Answer:

see below

Explanation:

Hypotonic solution is a very dilute solution to the more concentrated solution. Hypo means under . A solution with a lower concentration of solutes than the cytoplasm of a cell, that solution is hypotonic to the cytoplasm. The cell expands as water moves in.

Hypertonic solution is a more concentrated solution to cytoplasm. Hyper means above. A hypertonic solution has higher concentration of solutes than the cytoplasm of the cell. The cell shrinks as its cytoplasm loses water.

Isotonic solution is when two solutions of equal concentration are separated by a semi permeable. Iso means equal. Therefore, in isotonic solutions, water movement out of a cell balances the water movement into it. Cells in the body are usually surrounded by a fluid. The cytoplasm in the cell is usually isotonic to the fluid outside the cell. Hence, no net gain or loss of water by cells.

So, basically, if a cell is placed in a hypertonic solution, water will leave the cell, and the cell will shrink. In an isotonic environment, there is no net water movement, so there is no change in the size of the cell. When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell.

Recombination (crossing over) during prophase I of meiosis occurs when:

Answers

Answer:

meiosis before tetrads are aligned along the equator in metaphase I.

Explanation:

When chromatids "cross over," homologous chromosomes trade pieces of genetic material, resulting in novel combinations of alleles, though the same genes are still present. Crossing over occurs during prophase I of meiosis before tetrads are aligned along the equator in metaphase I

1. Gravity also increases

2. Gravitational attraction also decreases

3. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces. So as two objects are separated from each other, the force of gravitational attraction between them also decreases.

If a DNA molecule with a total of 2500 nucleotides has 1500 purines, how many guanines are in this DNA molecule?

Answers

Answer:

I'm pretty sure there would be 1000 guanines in the DNA molecule.

Explanation:

Hope this helps. . . <3

If a DNA molecule with a total of 2500 nucleotides has 1500 purines, total number of guanines are in this DNA molecule is 1000 guanines in the DNA molecule.

What will be the total number of thymines if a DNA molecule has a total of 1500nucleotides?

The DNA molecules would be given and it have 450 thymines if the DNA molecule has the total of 1500 nucleotides and the DNA molecule also have been known as the deoxyribonucleic acid has been made up of the double helix. The DNA molecule with the total of 1500 nucleotides would contain 750 cytosine and Thymines and 750 guanines and adenine.

Hence, we can have the expression:

C + T = 750

If there are 300 cytosines, hence;

300 + T = 750

T = 750 - 300

T = 450

A nucleotide has the monomer constituting DNA or RNA biopolymer molecules and the double-stranded DNA molecule posseses two strands of DNA made up of the nucleotides.

Therefore, If a DNA molecule with a total of 2500 nucleotides has 1500 purines, total number of guanines are in this DNA molecule is 1000 guanines in the DNA molecule.

Answer:A, C, E .

Explanation:

A) The presence of the owls is a selective pressure for the rodents.

C) Coevolution is occurring as each population is evolving in response to the other.

What is predator?

A predator is an organism that hunts, kills, and feeds on another organism known as the prey. Predation is a biological interaction between two species, where one species benefits by consuming the other species, and the other species is harmed or killed.

These two statements correctly evaluate the relationship between the predator and prey species in terms of evolution. The presence of owls as predators creates a selective pressure for rodents, where those with traits that allow them to escape predation are more likely to survive and pass on their genes.

This leads to the evolution of better-adapted traits in the rodent population over time. The interaction between owls and rodents can also be considered an example of coevolution, as changes in one population can drive changes in the other population, leading to a reciprocal evolutionary response.

Overall, the relationship between predator and prey species is complex and constantly evolving, with each population influencing the other's evolution over time.
