Explain how the structure of epithelium and the structure of connective tissue, specifically bone, relate to the function of the
Aneli [31]
<span>Epithelial tissue is densely packed cells that used most in the area where protection is needed. This cells mostly used in skin, some with more keratin which will increase their ability to protect. In bone, the main protective layer is calcium mineral which was deposited by osteocytes. Because this bone doesn't really need more epithelial cells. Bone tissue only needs a good vascularization and connective tissue to support it.

Which statement is an example of a scientific theory?
Vladimir79 [104]

Examples of a scientific theory

Scientific theories are testable and make falsifiable predictions. They describe the causes of a particular natural phenomenon and are used to explain and predict aspects of the physical universe or specific areas of inquiry (for example, electricity, chemistry, and astronomy).

The constant turnover of body tissues requires the ______ supplied by carbohydrates, proteins, and lipids
Lera25 [3.4K]

The constant turnover of body tissues requires the <u>chemical energy </u>supplied by carbohydrates, proteins, and lipids.

<h3> What is Chemical energy?</h3>
  • The bonds of chemical molecules contain energy.
  • Exothermic reactions are those in which chemical energy is released during the reaction, frequently in the form of heat.
  • Some of the heat energy needed for a reaction to continue can be stored as chemical energy in newly created bonds.
  • The body transforms the chemical energy in food into heat and mechanical energy.
  • At a power plant, coal's chemical energy is transformed into electrical energy. Through the process of electrolysis, the chemical energy in a battery can also generate electricity.

How can this PLR (pupillary light reflex) help you determine whether the lesion is in the eye itself or elsewhere?
Contact [7]

Answer:

Pupillary light reflex refers to the contraction that the pupils present when they light up. In cases of injury to the optic nerve, when the eye where the injured optic nerve is illuminated, since it cannot conduct the stimulus to the brain, neither pupil closes.

Explanation:

Pupillary light reflex refers to the reaction that causes the pupil to close with light thanks to the contraction of the sphincter of the pupil and to open in the dark thanks to the relaxation of that muscle by not receiving any stimulus. A light stimulus reaches the eye and in the retina it is transformed, through a chemical reaction, into an electrical stimulus that will be transmitted through the optic nerve and the visual pathways to the brain. The visual cells of the retina, rods and cones, also act as light receptors that control the pupil's motor activity. Thus, pupil-motor thresholds to light follow the same spectral sensitivity deviations as visual thresholds, which are a function of the state of light adaptation of the retina.

Please help!!!! very confused pt 2
Schach [20]

Answer:

If the genotype of the parents are <em>Iᵃi </em>and <em>I</em>ᵇ<em>i, </em>then four type of offspring will be produced.The genotype of the offspring are, <em>IᵃIᵇ, Iᵃi,Iᵇi, </em>and <em>ii.</em>

Explanation:

<em>IᵃIᵇ = </em>As the alleles are co-dominant in nature, so both type of alleles are expressed. The blood group will be AB. So, both A and B type of antigen will be found in plasma membrane of RBC.

<em>Iᵃi= </em>In this type of genotype only A type of antigen will be expressed in the membrane of RBC. The blood group will be A type.

<em>Iᵇi= </em>In this type of genotype only B type of antigen will be expressed in the membrane of RBC. The blood group will be B type.

<em>ii= </em>This is a recessive type of genotype. So, no antigen will be found on the membrane of the RBC. And the blood group will be O type.

The offspring's ratio will be 1:1:1:1.
