Answer: 1. The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone.

2. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands.

3. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.

Explanation: Hope this was helpful! :)

Answer:

Yes.

Explanation:

Yes, there is same effects of isotonic, hypotonic, and hypertonic extracellular environments on plant and animal cells because both cells are more similar to each other. If a plant or animal cell is placed in a hypertonic solution, water will go outside the cell, and the cell will shrink, in isotonic environment, there is no water movement inside or outside of the cell, so there is no change in the size of the cell, while on the other hand, if a cell is placed in a hypotonic environment, water will enter the cell, and the cell will turgor.

Also, isn't it supposed to be on December 2004??

Answer:

Genotype ratio 1:1, there are two types of genotype BB and Bb in equal ratio.

Phenotype ratio 1:0, because all offspring have allele B. “B” is dominant and there is no bb genotype, so recessive trait will not be shown.

Explanation:

Answer:

I don't know about the ration but it's going to be 25% chance for them to have an offspring with blue eyes as there is a presence of a dominant allele

Answer:

Insulin helps control blood glucose levels by signaling the liver + muscle fat cells to take glucose from the blood. It then helps the cells to take the glucose to be use for energy, and if the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.

Answer:

25%

Explanation:

According to this question, a seek stored seeds of a rare and endangered plant. In order to ensure that the seeds remain fresh, 120 seeds are selected to be grown. However, out of these 120 seeds, only 90 germinated. This means that only 90 of 120 seeds are fertile.

This further means that (120-90) = 30 seeds are infertile and hence, could not germinate. In percentage, this can be represented as:

30/120 × 100

= 1/4 × 100

= 100/4

= 25% of the selected seeds are infertile.

Answer:

Do Nitrogen, Phosphorus, and Potassium Fertilizers Do for Plants? Nitrogen in Fertilizer. In simple terms, nitrogen promotes plant growth. It is associated with leafy, vegetative growth. Phosphorus in Fertilizer. Phosphorus is involved in the metabolic processes responsible for transferring Each of these fundamental nutrients plays a key role in plant nutrition. Nitrogen is considered to be the most important nutrient, and plants absorb more nitrogen than any other element. Nitrogen is essential to in making sure plants are healthy as they develop and nutritious to eat after they’re harvested. Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.

Explanation: hope im right

Minerals like feldspar and mica are the main suppliers of potassium in soil. The earth provides phosphorus to plants. Usually in the form of synthetic fertilizer or livestock dung, farmers apply phosphorus to soil. The primary source of nitrogen in atmospheric deposition is the combustion of fossil fuels like coal and oil.

Fertilizer, a natural or synthetic substance with chemical components that enhance plant growth and productivity.

The primary sources of potassium in soil are minerals like feldspar and mica. Plants receive phosphorus from the ground.

Farmers add phosphorus to soil, typically in the form of synthetic fertilizer or livestock manure. The burning of fossil fuels like coal and oil is the main cause of nitrogen in the atmosphere.

Plants can take up nitrogen from the soil as [tex]NH^4^+[/tex] and [tex]NO_3[/tex] ions, but most of it is taken up as nitrate due to how common nitrification is in agricultural soils. As plant roots take up water, nitrate readily travels in their direction.

Thus, these are the sources of each of Nitrogen Phosphorus and potassium required for the growth of plant​.

Explanation:

A point mutation or substitution is a genetic mutation where a single nucleotide base is changed, inserted or deleted from a DNA or RNA sequence of an organism's genome.

Answer:

Bacterial cells come in different shapes: from rods, to spheres, to spirals

Explanation:

Answer:

if I remember right, a diploid is twice the amount of a haploid because diplood are pair chromosomes. So if there is 8 haploid there will be 16 diploid.

Explanation:

To find the diploid put the n of 2n.

One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become. Embryonic stem cells can become all cell types of the body because they are pluripotent.

Explanation:

Answer:

(B) and (E)

Explanation:

It is not option (A) because it says that Lactobacillus is a kind of bacteria that harms you, not is good for you, and parasitic bacteria are harmful to you, so not (A).

Not (C) because it does not make any sense whatsoever.

Not (D) since that says that S. typhi has a mutualistic relationship, which is good for both organisms, which is not true in this case.

It is (B) because the harmful bacteria, S. typhi is a parasite to humans.

It is also (E) since that says that the Lactobacillus bacteria does share a good relationship with humans.

Answer:

In order to be a carrier, the male must be a carrier of the allele without expressing it phenotypically. This can only happen when the inheritance is autosomal because he has a pair of autosomic chromosomes meanwhile he only has one X chromosome. So when the inheritance is X-linked, the allele of the X chromosome will always be phenotypically expressed

Answer:

two homologous chromosomes travel together into one new daughter cell.

Explanation:

in metaphase I the tetrads line themselves up at the metaphase plate and homologous pairs orient themselves randomly. in anaphase I centromeres break down and homologous chromosomes separate. in telophase I chromosomes move to opposite pols; during cytokinesis the cell separates into haploid cells.

Answer:

Gene flow within a population can increase the genetic variation of the population, whereas gene flow between genetically distant populations can reduce the genetic difference between the populations.

Explanation:

Gene flow within the population increases the genetic variability in the wolf population variation can be seen.

Gene migration is another name for gene movement. The movement of genetic material from one group to another is referred to as gene flow.

Through migration, gene flow can occur between two populations of the same species and is mediated via vertical gene transmission from parent to offspring and reproduction.

Any movement of people and the genetic material they carry from one community to another is referred to as gene flow, often known as migration.

Therefore the movement of genetic material from one population to another is known as gene flow.
