A disorder called osteogenesis imperfecta damages the auditory ossicles and results in hearing loss. why

tamaranim1 [39]

One of the components of the auditory system is the malleus incus and stapes that make up the auditory ossicles. Osteogenesis Imperfacta is a genetic disorder that affects the proper formation of connective tissue in the body.
Bones, on the one hand, are constituted by connective tissue. The disorder will consequently affect the formation and integrity of the auditory ossicles, therefore, leading to hearing loss.

A healthy way to gain weight would be to simply add more calories to your diet. Group of answer choices

marissa [1.9K]

Answer:

A healthy way to gain weight would be to simply add more calories to your diet is a TRUE statement.

Explanation:

The number of "calories" that an individual consumes and burns daily plays an important role in determining his/her weight. A person who consumes more calories than he burns daily could become overweight whereas if a person is consuming fewer calories than what he burns could cause him to lose weight.

The best way to gain weight is to "add more calories" to one's diet while also keeping in mind the number of calories being burnt daily. The newly added calories should sum up greater than the total calories burnt regularly.

Hence, the statement about adding calories in the diet to gain weight is true.

Why we need to monitor and effectively manage earth's resources

Because it's vital to the survival of all species, not just human, that we have resources such as food and water. Also that those resources be clean and healthy. We also need to manage resources such as oil to make sure there are fewer wars like the ones happening in the Middle East. If you need anything else just message me.

3. controls the function of different processes in the body

4. limbic system

5. Increase brain surface area

6. release hormones into the bloodstream

7. insulation

8. laughing has multiple positive functions in the body

Explanation:

Dopamine is a neurotransmitter (i.e., a chemical messenger) involved in responses to rewards, motivation and memory, while serotonin is another neurotransmitter that controls appetite, mood, wakefulness and sleep onset. The central nervous system (CNS) consists of the brain and spinal cord. The spinal cord acts as a conduit by which messages are sent from the brain to the body and from the body to the brain. Moreover, the brain acts to control all body abilities (e.g., thinking, talk, feeling, walking, breathing, etc). The autonomic nervous system is known to modulate different processes (e.g., blood pressure, digestion, breath) and internal organs (e.g., heart) by acting largely unconsciously, i.e., without a person's conscious effort. The limbic system is a part of the brain that acts to control emotions and memory by modulating autonomic/endocrine functions. Convolutions, folds, and fissures can increase brain surface area, thereby more neurons are packed into the cortex of the brain and thus it is possible to process more information. The endocrine system acts to release hormones into the bloodstream. These hormones travel in the blood to their target cells/tissues, where they regulate different functions (e.g., mood, growth, development, metabolism, reproduction, etc). The myelin is an insulating layer surrounding nerve cells that enables electrical impulses to transmit efficiently around the whole body. Laughing has multiple positive functions: release endorphin hormones that decrease stress, increases the number of immune cells and antibodies, stimulate the activity of internal organs (e.g., heart), quickly relax the muscles, contribute to increase the oxygen uptake rate in blood, etc.

Marianne is comparing two animals: a fruit fly and a fruit bat. She asks, "Do a fruit fly and a fruit bat share a common ancesto

Sonja [21]

The answer is; YES

All organisms share one common ancestor in the beginning of life. Different species have branched at different times from common ancestors hence he evolutionary tree looks like tree called a cladogram. The nodes represent the common ancestry while branches depict divergence. Therefore even fruit flies and the fruit bats even though they do not belong to the same species shared a common ancestor at one time in history.
