Answer:

Fat.

Explanation:

Bears have to survive on the fat. That is why they will eat so much to hibernate through the winter. If they don't have enough fat they wake up.

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).

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.

During ecological SUCCESSION, new species move into an area and colonize it. Subsequently, these species are also replaced by newer species.

Ecological succession can be defined as the process by which communities, i.e., a group of populations living in a determined area, change (evolve) over time.

This concept (ecological succession) refers to the sequential natural process of colonization of species in a particular ecosystem.

Ecological succession involves several consecutive stages:

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.

Answer:

I don't have the information from the text book but. People might more and more be using clean energy instead of fossil fuel is because fossil fuel is limited. It's a non-renewable, it takes millions of years to form. Also because global warming is making a big impact on our planet, using clean energy instead of fossil fuel can reduce slow green house emission.

The right whale got its name because it was the right whale to hunt—it moved slowly and would float after being killed. A North Atlantic right whale mother and calf were spotted off the U.S. southern coast by NOAA researchers during the 2020 breeding season.

North Atlantic right whales have been listed as endangered under the Endangered Species Act since 1970. The latest preliminary estimate suggests there are fewer than 350 remainings, with fewer than 100 breeding females. The number of new calves born in recent years has been below average.

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

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.

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.

The mitochondria are defective and do not produce sufficient protein to synthesize microtubules in the cilia and flagella. The plasma membrane of the alveoli is not permeable to carbon dioxide during respiration because it is too hydrophobic. The cells do not produce functional motor proteins in flagella and cilia.
