There are certain routes in a person’s body that will allow pathogenic bacteria to enter and cause illness or disease. Certain routes where pathogenic bacteria will enter is through inflamed skin or there is a presence of broken skin which we may describe as having scratch or cut. This is an open wound where bacteria would likely enter the body. Another passage way is the mouth, eyes, ears or nose. Lastly, sexual transmission, when it is done in an unprotected way.

The bones in a bird are hollow, reducing its weight for flight. This is an example of which characteristic of life?

dimulka [17.4K]

The bones in a bird are hollow, reducing its weight for flight, this is an example of ADAPTATION. The adaptive responses emerge as a consequence of different environmental pressures.

<h3>Adapatation and environment</h3>

Adaptation is an evolutionary process by which organisms adjust to the environment in which they live.

For example, the bones in a bird are hollow because this adaptive feature enables them to fly.

Adaptations are a consequence of the process of natural selection, i.e., the differential survival and reproduction of the fittest organisms.

What statement about the mechanism of hunger and satiety is true?

disa [49]

Answer:

The correct answer is: The ventromedial hypothalamus plays a role in satiety.

Explanation:

The hypothalamus is a part of the brain that controls many important bodily functions and connects both the nervous system with the endocrine system. The hypothalamus consists of several nuclei that have diverse functions and are located in 3 different regions.

The nucleus that plays a role in satiety is the ventromedial nucleus, terminating hunger and giving a sensation of fullness. It also plays a significant role in thermoregulation, among other things.

Neuropeptide Y, on the other hand, is a peptide that is released to make us feel hungry and encourage us to intake food (primarily carbohydrates).

Cholecystokinin is a hormone released by the small intestines after we had a meal, and its function is to improve digestion and make us feel full.

Fat cells DO release leptin, but the function of this hormone is to produce satiety, by stimulating anorexigenic (meaning they take hunger away) hormones and inhibiting orexigenic ones, like Neuropeptide Y.

Why can't astronomers measure the parallax of a star that is a million light years away?

motikmotik

One of the methods used widely to calculate the distance of nearby or closer objects in astronomy is Parallax. The distance of the stars are usually expressed in light years but the unit of distance is parsec or parallax second.

1 Parsec = 3.26 light years

Astronomers are not able to measure the parallax of a star that is a million light years away because the star is too far and the distance with which the start appears to move is too less to be calculated accurately.
