In skin, the cells of the epidermis connect to the basal lamina through cellular junctions known as hemidesmosomes. Select the cytoskeletal element that helps maintain the integrity of this connection. intermediate filaments both intermediate microtubules and microfilaments microfilaments only microtubules only
Answer:
The correct answer is ''intermediate filaments.''
Explanation:
The intermediate filaments are made up of thick and resistant protein fibers, with an intermediate thickness between that of the microfilaments and that of the microtubules. They provide mechanical resistance to the cell, avoiding the rupture of the membranes of the cells subjected to stress. The macromolecules that make up the basal lamina interact specifically with specific receptor proteins present in the plasma membrane of the cell base, which in turn interact in the cytoplasm with filaments of the cell cytoskeleton. When the junction is associated with intermediate filaments, it is a hemidesmosome and when it is the actin cytoskeleton that is anchored in the junction, it is focal contacts. Hemidesmosomes are formed by a dense plate attached to the cell membrane, in which the intermediate filaments are inserted by joining connection proteins, such as desmoplakin, which connect to the cytoplasmic portion of the integral proteins of the cell membrane, which belong to the family of integrins.

What is a negative feedback loop? Provide an example NOT related to Biology. (I will give brainliest)
Answer:
Examples of processes that utilise negative feedback loops include homeostatic systems, such as Thermoregulation if body temperature changes, mechanisms are induced to restore normal levels) Blood sugar regulation (insulin lowers blood glucose when levels are high glucagon raises blood glucose when levels are low)
Explanation:
Answer: A negative feedback loop is basically a procedure that uses criticism to make positive changes to a process

Match the following terms and definitions. 1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation chemoreceptors 2. neurons that detect chemicals such as those found in food effector 3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses electroreceptors 4. the structure that gives the response to an environmental change compound eyes 5. neurons that detect electrical fields action potential 6. secretion of hormones into the blood stream to affect distant processes endocrine
Answer:
1. an electrical nerve impulse sent by nerve fibers to the central nervous system for interpretation. Action potential.
2. neurons that detect chemicals such as those found in food. Chemoreceptors.
3. type of eyes many arthropods have; eyes that protrude outward and consist of many lenses. Compound eyes.
4. the structure that gives the response to an environmental change. Effector
5. neurons that detect electrical fields. Electroreceptors.
6. secretion of hormones into the blood stream to affect distant processes. Endocrine.
Explanation:
An action potential is a change in the internal charge of a cell due to depolarization. These changes allow the transmission of a message from any part of the body to the central nervous system. The central nervous system will interpret the message and will give a response.
There are different types of receptors in our bodies. Chemoreceptors are the ones that detect chemicals and produce an action potential or a neurotransmitter. These receptors respond to chemicals. Another type of receptor is the electroreceptors. They detect electrical fields and are only on the skin of aquatic animals.
Compound eyes have a large number of ommatidia. As a result, the anthropods with this type of eyes have a large view angle. In other words, every ommatidium sees an image, and the final product is a combination of all of them.
The effector is the structure that gives an answer once an affector has sent the message to the nervous system that there was a change in the environment.
There are different kinds of secretions, autocrine, paracrine, and endocrine. In the endocrine secretion, the gland secrets hormones into the bloodstream so that they can travel long distances up to their target cell, which is far from the gland.

Which type of reproduction results in
a greater variety of offspring?
Answer:
Sexual Reproduction

B. fossil evidence suggesting ancient genetic ancestors
C. unnecessary or nonfunctional organs in modern species
D. fossils of the same species found diverse geographic locations
The statement that is not an example of evidence that supports the theory of evolution is fossils of the same species found in diverse geographic locations.
What do you mean by Evolution?Evolution may be defined as a gradual and continuous process that runs over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.
Common genetic ancestors may be diverse into the number of other species due to the theory of evolution. Unnecessary or non-functional organs may be eliminated or shortened due to evolution.
Therefore, the statement that is not an example of evidence that supports the theory of evolution is fossils of the same species found in diverse geographic locations.
