Answer:

Insulin helps your body turn blood sugar (glucose) into energy. It also helps your body store it in your muscles, fat cells, and liver to use later, when your body needs it. After you eat, your blood sugar (glucose) rises. This rise in glucose triggers your pancreas to release insulin into the bloodstream.

Answer:

Explanation: 1. Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice or by the force of gravity acting on the particles.

2.  Organic, Clastic and Chemical Sedimentary Rocks.

3. The formation of coal takes millions of years, which is why it is an exhaustible and non-renewable natural resource.

It was formed around 300 million years ago when the earth was covered with swampy forests.

When plants in these forests- mainly trees, mosses, ferns, and reeds died, they fell into the swamps.

Thus there was a thick layer of dead vegetation in the swamp formed.

4. Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. A clast is a fragment of geological detritus, chunks and smaller grains of rock broken off other rocks by physical weathering.

6.Squeezed and compressed over time, the sediments become 'consolidated' (made solid) into layers of rock. Stratigraphy is the study of those layers Cementation occurs when dissolved mineral components deposit in the interstices of sediments. It is the sticking together of sediment that forms a rock.

7. It is used by marine biota to form a shell frame. Shells of marine animals are rich in carbonate minerals. When the marine animals die, the shells will accumulate and settle in a place so that rocks are formed.

8. This may be due to the overburden load, which is essentially the weight of all the material above the layer of minerals in question squashing them flat. Or it may be due to deformation caused by the movements of tectonic plates which often causes a form of deformation known as shearing where two things slide past each other. When this occurs in ductile rock masses, it acts to flatten and rotate mineral grains so that their long axis is parallel to the shear plane.

Explanation:

Lack of oxygen would have little or no effect on these organisms in the Gulf of Mexico. The cellular process that is most affected by the lack of the oxygen is respiration.

We would have to know that the oxygen molecule is one the gases that is very important to the life of the organism. As such, oxygen is expected to be abundant in the environment. However, it should be known that the rate of the dissolution of the oxygen in water is quite slow.

As such, we could have some of the aquatic habitats that could be shown to be low in the amount of the oxygen that can be found in that water body and we can be able to say that such a water body is hypoxic.

An example of one of the water bodies that can be seen to be hypoxic in nature is the water body at the Gulf of Mexico.

Isovolumic relaxation period or early diastole - End of ventricular contraction to the beginning of the atrial contraction.

The relaxed portion of the cardiac cycle known as diastole is when the heart's chambers are refilled with blood. The relaxing of the atria occurs during atrial diastole, whereas the relaxing of the ventricles occurs during ventricular diastole.

Isovolumic relaxation time is the period of time between the aortic component of the second heart sound and the beginning of filling caused by the opening of the mitral valve in the cardiac cycle.

The frequency of the dominant allele is 0.99, the frequency of the recessive allele is 0.01, and the percentage of heterozygous individuals (carriers) in the Hispanic population is 1.98%.

What is Frequency?

Frequency refers to the number of occurrences of a particular event or phenomenon in a given unit of time or space. In genetics, frequency typically refers to the number of occurrences of a particular allele or genotype in a population. For example, the frequency of a particular allele in a population is the proportion of that allele in the total number of alleles at the same locus in that population.

To calculate the frequency of the dominant and recessive alleles, we can use the Hardy-Weinberg equation:

Since cystic fibrosis is a homozygous recessive condition, we know that  \(q^{2}\)= 1/10,000, or 0.0001. We can solve for q by taking the square root of both sides:

q = √(0.0001) = 0.01

To find p, we can use the fact that p + q = 1:

p = 1 - q = 1 - 0.01 = 0.99

So the frequency of the dominant allele is 0.99, and the frequency of the recessive allele is 0.01.

To calculate the percentage of heterozygous individuals (carriers), we can use the equation:

2pq * 100%

where 2pq represents the frequency of heterozygous individuals. Plugging in our values, we get:

2pq = 2(0.99)(0.01) = 0.0198

So the percentage of heterozygous individuals in the Hispanic population is:

0.0198 * 100% = 1.98%

The difference is due to the inheritance pattern. Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one.

⇒ Blood type is coded by a diallelic Rh gene that expresses complete dominance.

The allele Rh+ dominates over the allele Rh-.

Genotyopes and Phenotypes are as follows,

To express Rh-, a person must inherit two recessive alleles from their parents.

⇒ Color-blindness is an X-linked condition coded by a recessive allele.

As most sex-linked genes, it is transmitted together with the X chromosome.

The phenotype depends on the number of recessive alleles and the sex of the person.

Genotyopes and Phenotypes are as follows,

In this case, only one recessive allele is enough to express the affection.

In conclusion, Blood type needs two recessive alleles to express Rh-. Color-blindness needs only one recessive allele.

Answer:

Osmosis is an important process that occurs in living things. The following are examples of biological processes that rely on osmosis:

1. Cellular hydration - Osmosis plays a role in hydrating or dehydrating cells. Water can move into or out of cells via osmosis, depending on the concentration gradient across the cell membrane.

2. Nutrient uptake and waste removal - Cells require nutrients to carry out their metabolic functions and produce waste products that need to be removed. Osmosis is involved in the movement of these substances in and out of cells.

3. Regulation of blood pressure - Osmosis is important in regulating blood pressure. For instance, when the concentration of ions in the blood increases, osmosis causes water to move from surrounding tissues into the bloodstream to restore balance.

4. Root absorption in plants - Osmosis allows plants to absorb water and minerals from soil through their roots. The concentration gradient between the soil and the root cells enables water to move via osmosis.

5. Osmoregulation - This process involves maintaining a balance between water and solute concentrations in living things. For instance, freshwater fish depend on osmosis to expel excess water from their bodies and maintain the right balance of ions, while marine fish drink large amounts of water to balance the high salt concentration in their bodies.
