Structures found in the dermis are collagen, elastic fibers, and extrafibrillar matrix.

Structural components of the dermis:

The dermis or corium is a layer of skin between the epidermis and subcutaneous tissues, that primarily consists of dense irregular connective tissue and cushions the body from stress and strain.

Structural components of the dermis are collagen, elastic fibers, and extrafibrillar matrix. It also contains mechanoreceptors that provide the sense of touch and thermoreceptors that provide the sense of heat.

Collagen: Collagen is the main structural protein in the extracellular matrix found in the body's various connective tissues.

Elastic fibers: In the dermis of animals with single, primary hair follicles are derived from cells lining the hair follicle or from the ends of the pili muscle, which anchors the muscle to the matrix or to the hair follicle. Each follicle is interconnected with elastic fibers.

Extrafibrillar matrix: The dermal material lying outside the cells, and not consisting of either collagen fibers or elastic fibers, is called the extrafibrillar matrix.

The dermis, the skin's next layer, is a thick layer of fibrous and elastic tissue (made mostly of collagen, with a small but important component of elastin) that gives the skin its flexibility and strength. The dermis contains nerve endings, sweat glands and oil (sebaceous) glands, hair follicles, and blood vessels.

Answer;

Three ways that scientist can use to avoid bias are;

- Sampling method

- Using blind study

- Repetition

Explanation;

Sampling method involves the studying of a small quantity of a particular aspect in order to form an opinion about the whole population. To avoid bias its important to obtain samples that are appropriate and that would cover the entire participants studied.

-Repetition involves repeating a particular experiment several times in order to ensure that one gets the same results that is ensure accuracy of the results.

-Blind study involves an experiment in which the control and the variable groups are conceal from the participants until after the end of the experiment. It is an important factor to avoid bias in scientific research.

Final answer:

Scientists can minimize bias in scientific investigations through randomization, blind studies, and double-blind studies.

Explanation:

There are three ways that scientists can minimize bias in scientific investigations:

1. Randomization: Scientists can assign participants or samples randomly to different groups or conditions to ensure that each group is similar and reduce bias.
2. Blind studies: Scientists can conduct blind studies where participants or researchers are unaware of the group assignments or the purpose of the study to prevent biased behavior or expectations.
3. Double-blind studies: Scientists can also conduct double-blind studies where both the participants and the researchers are unaware of the group assignments to further avoid bias.

Answer:

The ozone layer absorbs most of the Sun's ultraviolet radiation in the Earth's stratosphere.

Explanation:

It is important to humans because it protects us from getting sun burnt and from our body receiving too much radiation.

Answer:

it protects us from radiation from the sun

Answer:

The correct answer is option B, All four children have genes for blue eyes.

Explanation:

The allele (representative of any trait) carried by genes expresses themselves at specific locus devise a phenotype. Traits exhibited can be represented by genotype and phenotype of an individual.  

Here in this example, blue colour of eyes is a trait which is common in all the children of the family, this simply signifies that genes carrying the alleles is same in all the children.
