B.
The population is likely to evolve to have stronger pectoral fins.

C.
Walking catfish with stronger pectoral fins and those with weaker pectoral fins will both become extinct.

What might happen at the cellular level of the plant if there was no water available for photosynthesis?

Answers

Answer:

when water levels are low due to water stress, photosynthesis can slow or even stop, causing internal food supplies vital to other processes to diminish or disappear -- yellowing may also occur if photosynthesis stops completely.

Explanation:

If there was no water available for photosynthesis, the cellular level of the

plant will be affected negatively in areas such as shrinking of cells and

decrease in photosynthetic activities.

Plants require water to produce food in the process known as

photosynthesis. When there is no water the photosynthesis is slowed down

and the cells begin to shrink.

The shrinking of cells then results to the wilting and yellowing of leaves of the plant.

how would you describe what the cells of each stage of the cycle look like ? what are the visible features of the cells.
Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis​

Answers

Interphase:

Is known as the resting stage. Replication of DNA occurs.

- G1

-S

-G2

Prophase:

The chromosomes are visible,  centrioles are formed and begin to move to opposite sides. This is where you see the dissolving of the nuclear membrane.

Metaphase:

The chromosomes line up in the centre of the cell.

Anaphase:

This when the cell divides (should look like two circles splitting) you will see the spindles begin to shorten which pull chromatids apart.

Telophase:

The nuclear membrane is reformed.

Explain how diffusion is used to support the life processes of animals.

Answers

Answer:Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow.

Explanation:Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products. This table shows examples of substances required by cell and associated waste products.

Oxygen and glucose react to form carbon dioxide and water along with ATP (a source of energy) in the process of aerobic respiration. Therefore, oxygen and glucose must be taken up by the cell, and typically the concentration of these molecules outside the cell is greater than inside. Therefore, the overall net movement of these molecules will be down the concentration gradient, and they will move into the cell via diffusion. Similarly, the carbon dioxide produced is a waste product and moves out of the cell, again via diffusion down its concentration gradient.

What are three kinds of volcanoes? What makes them different?

Answers

Answer:

Composite, shield, cinder cones, and supervolcanoes are the main types of volcanoes.

Composite volcanoes are tall, steep cones that produce explosive eruptions.

Shield volcanoes form very large, gently sloped mounds from effusive eruptions.

Volcanoes have several shapes, which are controlled by the composition of the magma and the nature of its eruption. If a volcano produces very fluid lava (low in the compound SiO2, or silica), the magma flows a long distance before it cools, making a flat, shield-shaped volcano.

Answers

Pp=50% and pp=50% so it’s a 50/50 chance of what the offspring will be

The possible genotype of all the offspring will be PP, and Pp as per the given situation.

What is genotype?

An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries in a specific gene or genetic region are also referred to as the genotype.

The term "genotype" broadly refers to an organism's genetic make-up; in other words, it characterizes an organism's whole gene pool.

The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning.

In the Punnett square attached, the genotype of the organism is PP and Pp, which means the generation will be having purple flower.

Thus, the possible genotype will be 50% PP and 50% Pp.

C. Fructose feeds sperm, enabling them to survive long enough to fertilize an egg.

D. Fructose provides energy for the development of the fertilized egg.

I’ll give brainiest:)

Answers

Answer:

The answer is C

Explanation:

I just got it right on the quiz

Fructose feeds sperm, enabling them to survive long enough to fertilize an egg.

Semen contains fructose because it feeds the sperm, enabling them to survive long enough to fertilize an egg. Therefore, the correct answer is option C.

What is fructose?

Fructose is a type of sugar that provides energy to the sperm as they travel through the female reproductive tract in search of an egg to fertilize. Sperm have a limited lifespan outside the male body, so it is essential that they are supplied with enough energy to reach and fertilize an egg before they die.

The fructose in semen provides this energy to the sperm, allowing them to survive and swim towards the egg. Once inside the female reproductive tract, the fructose is absorbed by the sperm and used to fuel their movement towards the egg. Without the fructose in semen, the sperm may not have enough energy to reach the egg and fertilize it.

The hours of daylight can vary greatly because of latitude. How would being near the equator shape the amount of sunlight per day in those countries? Explain your answer.

Answers

Answer:

Explanation:

The amount of daylight that is received is directly proportional to how close the sun is to each hemisphere. This happens due to Earth's inclined axis which changes as the Earth rotates and causes more daylight in the Northern or Southern hemispheres which is when summer starts in each. That being said the Equator is the only location that has an even amount of sunshine all year round. This is why it is always hot and Equator cultures only recognize dry and wet seasons but still consider it summer all year round.

A cell that is placed in distilled (plain) water will swell up because it fills

Answers

Answer:

If a cell is placed in a hypotonic solution, water will move into the cell. This causes the cell to swell, and it may even burst. A hypertonic solution means the environment outside of the cell has more dissolved material than inside of the cell. If a cell is placed in a hypertonic solution, water will leave the cell.

Answer:

C. Bases

Explanation:

Deoxyribonucleic acid, commonly known as DNA, is the a type of nucleic acid that serves as the genetic material in living organisms. DNA holds information or instructions needed for the synthesis of useful products like proteins that is responsible for growth, reproduction, and general survival of organisms. Hence, it is referred to as the "BLUEPRINT OF LIFE".

However, in the structure the of the DNA molecule, it contains certain monomeric building blocks called NUCLEOTIDES. These nucleotide bases are of four types namely: Adenine, Thymine, Guanine and Cytosine. It is upon these order of nucleotide bases that instructions, or 'code', in our DNA is dependent upon.
