Answer:

The correct answer is D.) the curved surface of Earth.

Explanation:

The intensity of sunlight on Earth is affected by the curved surface of Earth, which causes the sunlight to spread out over a larger area. As a result, the intensity of sunlight is less at any given point on Earth's surface than it would be if Earth had a flat surface. This also explains why the poles receive less sunlight than the equator, as sunlight is spread out over a larger area near the poles due to the curvature of the Earth.

Factors such as the mass of Earth, the speed of Earth, and the number of rotations of Earth do not directly affect the intensity of sunlight on Earth.

By 1984 the Schaus Swallowtail butterfly was reduced to a total of 70 individuals.

The Schaus swallowtail butterfly is a species of butterfly that is considered to be endangered. It is indigenous to Florida's tropical hardwood forests. The Schaus Swallowtail butterfly has a wingspan of about 2.5 to 3 inches and has yellow and brown colored wings. It was designated as an endangered species on July 31, 1975, under the Endangered Species Act.

The species has been in decline for many years, and by 1984, only 70 individuals were counted. The primary reasons for their decline were habitat loss and insecticide use. However, due to intensive conservation efforts and habitat restoration, the Schaus Swallowtail population has since recovered, and their population has risen to more than 2,000 individuals.

Answer:

The plasma membrane is a thin layer of lipid molecules that surrounds the cell and separates the inside from the outside. The fluid mosaic model describes the structure of the plasma membrane as a two-layered structure of phospholipids with embedded proteins. This model explains how the structure of the plasma membrane allows it to act as a selective barrier, regulating the movement of substances in and out of the cell.

Structure S in the plasma membrane is represented by the phospholipids, which form a lipid bilayer with hydrophilic heads facing outwards and hydrophobic tails facing inwards. The hydrophilic heads are in contact with the extracellular fluid and intracellular fluid while the hydrophobic tails are in the middle of the membrane. The phospholipid bilayer provides a barrier that separates the inside and outside of the cell, restricting the movement of hydrophilic and large molecules through the membrane while allowing the passage of small and hydrophobic molecules.

Structure T represents the integral membrane proteins that are embedded in the lipid bilayer. These proteins have different functions, such as transport of molecules, cell signaling, and catalyzing chemical reactions. The proteins also contribute to the selective permeability of the membrane by regulating the movement of specific molecules in and out of the cell. For example, channels and carrier proteins regulate the movement of ions and larger molecules through the membrane while receptor proteins receive signals from the outside of the cell and relay them to the inside of the cell.

In summary, the plasma membrane is mainly composed of phospholipids and proteins according to the fluid mosaic model. The phospholipids form a lipid bilayer that acts as a barrier, while the proteins embedded in the bilayer regulate the selective permeability of the membrane by facilitating the movement of specific molecules in and out of the cell.

A tissue is a group of cells that does the same function.

After one generation of random mating under Hardy-Weinberg equilibrium, the expected genotype frequencies will be: 0.36, 0.16, and 0.48

The Hardy-Weinberg principle describes the relationship between genotype and allele frequencies in a population that is not undergoing any evolutionary change. According to this principle, if a population is in Hardy-Weinberg equilibrium, the genotype frequencies will remain constant from one generation to the next.

To determine the expected genotype frequencies after one generation of random mating under Hardy-Weinberg equilibrium, we need to first calculate the allele frequencies. Since there are two alleles (A and a), the sum of their frequencies must equal 1.

Let p be the frequency of allele A and q be the frequency of allele a. The sum of p and q is 1, so we can calculate q as follows:

q = 1 - p

From the given genotype frequencies, we can infer that:

The frequency of aa = q^2 = 0.6

The frequency of aa = p^2 = 0.2

The frequency of aa = 2pq = 0.2

To solve for p and q, we can use the following equations:

p^2 + 2pq + q^2 = 1 (total frequency of all genotypes)

p + q = 1 (total frequency of alleles)

Substituting in the given genotype frequencies, we get:

(p^2) + 2(0.2)(q) + (q^2) = 1

p + q = 1

Solving these equations simultaneously, we get:

q = 0.6

p = 0.4

Therefore, after one generation of random mating under Hardy-Weinberg equilibrium, the expected genotype frequencies will be:

aa = (0.6)^2 = 0.36

aa = (0.4)^2 = 0.16

aa = 2(0.4)(0.6) = 0.48

These expected genotype frequencies match the original genotype frequencies, indicating that the population is in Hardy-Weinberg equilibrium.

A weak, subthreshold stimulus will result in a small depolarization at the receiving end of the neuron.a weak, subthreshold stimulus will primarily result in a small depolarization at the receiving end of the neuron, but it will not initiate an action potential or trigger neurotransmitter release.

When a neuron receives a stimulus, it can either be strong enough to generate an action potential or be subthreshold, meaning it does not reach the threshold necessary to trigger an action potential.

In the case of a weak, subthreshold stimulus, the neuron will undergo a small depolarization at the receiving end, known as the dendrites and cell body.

The dendrites and cell body of a neuron contain numerous ion channels, including ligand-gated channels and voltage-gated channels.

These channels regulate the movement of ions, such as sodium (Na+), potassium (K+), and chloride (Cl-), which are crucial for generating electrical signals in the neuron.

When a subthreshold stimulus is received, it causes a small influx of positive ions, typically sodium ions, into the neuron through ligand-gated channels.

This influx of positive charge results in a slight depolarization of the neuron's membrane potential.

However, the depolarization does not reach the threshold required to initiate an action potential.

As a result, the subthreshold stimulus is unable to propagate as an action potential along the axon of the neuron.

Instead, the small depolarization may weaken as it travels along the neuron's dendrites and cell body.

This weak signal may not be sufficient to trigger the release of neurotransmitters at the axon terminal, which is necessary for communication between neurons.
