It is true that if a cat's somatic cells have 38 chromosomes, the haploid cells have 19 chromosomes. Details about chromosomes can be found below.

Meiosis is the process of division that results in the formation of daughter cells that are genetically different from the parent cell.

In meiotic division, the chromosome number of the parent cell reduces by half in the daughter cells or gametes.

This means that if a cat's somatic cells have 38 chromosomes, the haploid cells have 19 chromosomes as a result of meiotic division.

Answer:

The believe the correct answer is option E.

The relatively large number of new mutations that occur in the human genome in each generation is tolerable because: most of the human genome is noncoding DNA, so few mutations affect human proteins. Therefore, the correct option is D.

A human genome refers to the complete set of sequences of the nucleic acids that are present in the humans. The human genome contains a relatively large amount of noncoding DNA, which does not code for proteins and is therefore less subject to selective pressures.

Option A, humans have excellent protein repair mechanisms, and Option C, humans have excellent DNA repair mechanisms, are partially true, but do not fully account for the tolerability of new mutations in the human genome.

Option B and E are also not true, as changes in human proteins have relatively small effects on their cells' structures and functions, is not entirely true. Therefore, the correct option is D.

Answer: the speed of the body

Explanation: kinetic energy is equal to the the half of the multiple of mass and speed so the increasing and decreasing of the speed has a greatest impact on the kinetic energy.

Add me as the brainleist please!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The kinetic energy of a body depends on its mass and velocity but velocity has the greatest impact on kinetic energy.

The energy that an object has as a result of motion is known as kinetic energy. It is described as the effort required to move a mass-determined body from rest to the indicated velocity. The SI unit of kinetic energy is the joule (J).

Radiant, thermal, acoustic, electrical, and mechanical kinetic energies are the basic categories. The capacity to perform work is kinetic energy's most significant quality. Kinetic energy can be increased by increasing mass and velocity and can be decreased by decreasing them.

Kinetic energy depends on both the mass and velocity of the body but it is most affected by velocity.

2. The eagle can't afford to make any mistakes because we are told, "even the slightest injury can leave it too weak to hunt and cause it to stave."

3. More eagles means more hares are hunted, and as more hares are been killed, the lesser the hare population.

4. The increase in the predator population leads to a reduction in the population of the prey. In other words, as more predators start looking for prey to eat, the prey population decreases.

5. In simple words, a keystone species is a type of predator whose presence in the community has far-reaching effects on other species in the community. One common example is the sea star species found in coral reefs, see stars feed on mussel and sea urchin thereby helping to regulate the population of mussels and sea urchin. Doing this ultimately helps other species survive.

6. A limiting factor is an attribute or factor that reduces the exponential growth in the population of an organism.

7. Camouflage allows preys to hid from their predators. Usually made possible by their physical appearance.

Certain types of genetic mutations can change proteins in ways that make healthy cells to become full of cancer.

The predicted frequency of homozygous dominant will be 0.64. The correct option is A.

A homozygous dominant genotype is defined as an organism with two dominant alleles for a trait.

In the absence of factors responsible for evolution, the Hardy-Weinberg law states that the allele and genotype frequencies in a population remain constant. The total of the frequencies is one.

\(p^2 + 2pq + q^2 = 1\)

Here, it is given that,

The frequency of the recessive allele is (q) = (0.2).

Since p + q = 1

Frequency of dominant allele = (p = 1-0.2 = 0.8).

The frequency of homozygous dominant = \(p^2=(0.8)^2\) = 0.64

Thus, the correct option is A.

This area support can support about 15 bears if each bear eats 10 fish in a day.

Grizzly bears are a large specie of bears. There are different ranges of colors i.e. from very light tan to dark brown. These bears have a dished face, rounded ears, and a shoulder hump. The hump is the place where a mass of muscles attach to the backbone of the bear and gives the bear more strength for digging. Grizzly bears feed mostly on animals that die in the winter season, but the bear can also hunt elk calves. Other items are eaten during spring like grasses, sedges, dandelions, clover, horsetail, and ants. A river provides about 150 fish per day so the carrying capacity of this region has 15 bears.

So we can conclude that 15 bears can be supported by the region without damaging its fish population.

Random mutation is not an mechanism of evolution .

Five important factors for evolution mechanism are Natural Selection, genetic drift, gene flow, mutations, and non random mating. Through these process members of a population differs greatly in their traits.

Natural selection is the most important mechanism of evolution, other evolutionary mechanisms can also change the frequencies of traits in populations. These include mutation, genetic drift and migration. Natural selection have 5 basic and major components These are Variation (individual have variation in appearance and behavior ), Inheritance( traits are continuously passed on from parent to offspring), Selection, Time and Adaptation.

Schwann cells produce a myelin sheath around a portion of just one axon, but oligodendrocytes can surround a segment of multiple axons.So, choice d is the right one.

Any of the peripheral nervous system's cells that create the myelin sheath that envelops neuronal axons are known as Schwann cells, also known as neurilemma cells.

Theodor Schwann, a German biologist, is remembered as the person who first identified Schwann cells in the 19th century.

These cells are comparable to an oligodendrocyte-class of neuroglia found in the brain and spinal cord.Oligodendrocytes do not produce myelin; only Schwann cells do.

During embryonic development, Schwann cells diverge from neural crest cells, and they are prompted to multiply.

Spinal interneurons inhibit antagonist motor neurons in a process called reciprocal inhibition.

Reciprocal inhibition is a neurophysiological phenomenon that occurs within the spinal cord. When a specific motor neuron is activated to generate a contraction in a muscle (agonist muscle), spinal interneurons simultaneously inhibit the motor neurons responsible for the antagonist muscle. This inhibition helps to ensure coordinated and smooth movement by preventing simultaneous activation of both agonist and antagonist muscles.

The spinal interneurons achieve reciprocal inhibition by inhibitory synaptic connections with the motor neurons of the antagonist muscle. This inhibitory input reduces the excitability of the antagonist motor neurons, preventing their activation and contraction during the movement.

Reciprocal inhibition is an important mechanism for maintaining balance, precision, and control in motor movements, allowing for efficient and coordinated muscle activity.

A flatworm typically hunts and eats other organisms to obtain its food. Flatworms are carnivorous and have a simple digestive system that consists of a mouth, pharynx, and gut.

They use their mouth to capture prey, such as small invertebrates, and their pharynx to suck in and digest their food.

Some flatworms, such as certain species of planaria, are scavengers and may feed on decaying organic matter. However, this is not their primary mode of obtaining food, as their digestive system is better suited to processing animal tissue.

Flatworms do not undergo photosynthesis, as they are not photosynthetic organisms and do not have chloroplasts or other structures required for this process. They also do not filter pond water, as their diet consists primarily of solid food sources.

In summary, flatworms are carnivorous organisms that hunt and eat other organisms as their primary mode of obtaining food.

The iron-sulfur world hypothesis is a scientific theory that proposes a scenario for the origin of life on Earth. According to this hypothesis, organic matter, such as the building blocks of life, could have emerged in an environment rich in iron and sulfur minerals.

The iron-sulfur world hypothesis suggests that early Earth had a reducing atmosphere with high concentrations of iron and sulfur compounds.

Under such conditions, these minerals could have catalyzed a variety of chemical reactions that played a crucial role in the synthesis of organic molecules, including amino acids and nucleotides.

Iron-sulfur clusters present in these minerals possess unique redox properties, enabling them to facilitate important biochemical processes.

Furthermore, iron-sulfur clusters are found in many enzymes and proteins involved in key metabolic pathways in modern organisms.

This observation supports the idea that these clusters were fundamental in the early evolution of biochemical systems.

The iron-sulfur world hypothesis proposes that the prebiotic synthesis of organic matter occurred in association with these minerals, providing a plausible explanation for the origin of key biomolecules.

In summary, the iron-sulfur world hypothesis suggests that the rich chemistry of iron and sulfur minerals played a significant role in the formation and synthesis of organic matter, laying the foundation for the emergence of life on early Earth.

Answer:

I would say C:wind erosion

Explanation:

can I have brainliest

Answer:

The distribution of biomes is affected by climate and disturbance. Disturbances, such as hurricanes, allow an opening for new species to enter a biome, as well as the death of other organisms. Depending on the climate, only certain new species will be able to thrive in the environment. If a new species does thrive, it could use too much of a resource, or eliminate a different species from the biome. Both the biotic and the abiotic factors determine the resources in the biome. Also, temperature and precipitation may limit the growth of certain organisms.

Explanation:

If abiotic factors change organisms could migrate, die, or thrive. A species may not be able to continue producing offspring or they may not be able to adapt, causing death or extinction. Extinction may affect the food chain. There could be a die-off of the higher branches of the ecosystem. Depending on the changing abiotic factors, some organisms may survive better in different conditions, this may also change the species in the ecosystem.
