the endosymbiont theory proposes a model for the evolution of mitochondria. according to the model, an ancestral eukaryote engulfed a small, free-living prokaryotic organism. the engulfed prokaryote then formed an endosymbiotic relationship with the eukaryotic host. which of the following observations best supports the model?

Answers

Answer:

Mitochondria and some prokaryotes share similar metabolic reactions that produce ATP.

Correct. The observation that mitochondria and some prokaryotes share similar metabolic reactions that produce ATP supports the model that mitochondria are endosymbionts that originated from a free-living prokaryote.

what is the importance of predation in an ecosystem​

Answers

Answer:

Without predatation, things wouldn't eat each other.

Rabbits won't eat grass, Wolves won't eat Rabbits, and so on...

If it were to continue this way there wouldn't be a single animal on this planet. (everything living except plants that only rely on the sun.)

It's a food chain. A CHAIN. Each varible depends on each other.

And a food chain has a direct impact on the ecosystem.

For example:

No rabbits mean there is so many grass and carrots left behind

No wolves means there are too many rabbits

So that means

No wolves

Whatever eats the wolves wont be alive

Whatever eats THAT wouldn't be alive

Does “survival of the fittest apply to domesticated animals? Why or why not? *

Answers

Answer:

Yes.

Explanation:

This survival of the fittest is instinct helps domestic animals live. Just because an animal is domesticated, does not mean that instincts go away. Those instincts like hunting may get suppressed, but not taking away.

Answer:

Survival of the fittest does not apply to domesticated animals. This is because these animals don't live in the wild so they don't have to run after things and kill them. Their food comes out of a tin and is provided by human beings. They don't have any predators so their lives are seldom at risk. Thus, they don't need to be fitter or more powerful than other animals in any way.

Lets take the example of pet dogs. We keep them for our support or simply because we enjoy their company. We provide them with food, shelter etc. and protect them. Since, we basically do everything for them; they need not evolve into a stronger, more powerful species.

However, in the case of stray dogs, they have to fight for their survival. They have to fight with other dogs for food and shelter. Hence, survival of the fittest will apply here as the strongest dog gets to eat.

Hope this helps.

If the individuals in a population mate at random, and if allele h1 is at frequency 0. 60, what is the frequency of h1h1 offspring?.

Answers

Answer: Frequencies of two alleles in a gene pool before and after many random matings

Explanation:

Frequencies of two alleles in a gene pool before and after many random matings

The allele frequency of h1h1 in offspring is 0.36 if individuals in the population mate at random, the allele of interest is divided by the total number of copies of all the alleles.

What is the frequency of the allele?

The number of times the allele of interest is detected in a population is divided by the total number of copies of all the alleles at that particular genetic locus in the population to compute the allele frequency.

In a population, if individuals mate at random sampling if h1 has a frequency of 0.60, the frequency of h1h1 offspring is 0.36, in the population.

The frequency of alleles can be expressed as a decimal, a percentage, or a fraction. Allele frequencies vary from 0 (present in no people) to 1 (present in all individuals); in a population, all allele frequencies for a particular gene add up to 100%.

Therefore 0.36 is the frequency of h1h1 in the population for individuals at random mates for h1 frequency of 0.60 in the population.

Are the following organelles found in plant cells, animal cells, or both?

Nucleus
Cell membrane
Plasma membrane
Mitochondria
Vacuole
Endoplasmic reticulum
Cell wall
Chloroplasts
Ribosomes
Cytoplasm

Answers

Answer:

Explanation:

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information

The the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions.

The plasma membrane is the same as a cell membrane

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate

​Vacuole. A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance.

The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

A ribosome is a cellular particle made of RNA and protein that serves as the site for protein synthesis in the cell. The ribosome reads the sequence of the messenger RNA (mRNA) and, using the genetic code, translates the sequence of RNA bases into a sequence of amino acids.

The cytoplasm is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell. All of the functions for cell expansion, growth and replication are carried out in the cytoplasm of a cell.

Both the mother and father of a son with colorblindness have normal vision. From whom did the son inherit the gene for colorblindness

Answers

Answer:

The blind son inherited his gene for colorblindness from his father.

Explanation:

The X chromosome is where color blindness is most frequently inherited as a recessive trait. In genetics, this is referred to as X-linked recessive inheritance. As a result, men tend to be affected by the illness more frequently than women (8% male, 0.5% female).

What are the characteristics of colorblindness inheritance?

There is a 50% chance that the sons of a color-blind father and a mother who has the gene will also be color-blind. However, their daughters will have a 50% risk of having the condition and a 100% chance of carrying the gene.

The 23 chromosome is known as the “sex chromosome,” and it is passed from mother to son. Red/green color blindness is the most common type of this condition.

As it aids in identifying sex, the 23rd chromosome is known as a sex chromosome.

Therefore, The blind son inherited his gene for colorblindness from his father.
