Explanation:

The gametophyte generation is haploid and produces gametes that fuse to form a diploid zygote, which develops into the sporophyte, completing the cycle.

Green algae are a diverse group of photosynthetic organisms that exhibit a range of life cycles. Some, like Ulva, demonstrate an alteration of generations, meaning they alternate between a haploid (one set of chromosomes) and a diploid (two sets of chromosomes) phase. In Ulva, the haploid phase is called the gametophyte generation, while the diploid phase is known as the sporophyte generation. The gametophyte generation produces haploid gametes, which fuse to form a diploid zygote, giving rise to the sporophyte generation. The sporophyte generation produces diploid spores, which eventually undergo meiosis to form haploid cells, starting the cycle anew. This complex life cycle is typical of many green algae and provides a means of genetic variation through sexual reproduction.

Hardwired characteristics of the brain that attempt to keep us in balance by correcting deficiencies are referred to as homeostatic mechanisms.

Homeostasis is the body's ability to maintain a stable internal environment despite external changes.

In the context of the brain, homeostatic mechanisms involve various processes that regulate physiological functions and maintain optimal levels of essential substances.

These mechanisms can include feedback loops that detect imbalances and initiate corrective actions.

For example, if there is a deficiency in a particular nutrient or hormone, the brain may activate mechanisms to increase its production, decrease its consumption, or enhance its absorption from the environment.

Homeostatic mechanisms play a crucial role in ensuring the body's overall stability and functioning, helping to maintain proper levels of various substances and promoting overall well-being.

Answer: C) The benthic invertebrates would decrease in population size because they are eaten by the sea ducks and the phytoplankton would increase in population size.

Explanation:

The benthic invertebrates are eaten by sea ducks. Sea ducks are eaten by bald eagles. If the bald eagle was removed, there would be more sea ducks because they will have no more predators. Since there are more sea ducks, they will need to eat more food, like benthic invertebrates. The benthic invertebrates would have a lower population because the sea ducks eat more of them.

Why not the other answers:

A) The bivalves would not increase in population size. Without the bald eagle preying on sea ducks, there would be more sea ducks, who need to eat more food, such as eating more bivalves.

The phytoplankton would not decrease. With sea ducks eating more food, more benthic invertebrates are eaten. There would be less benthic invertebrates to eat phytoplankton.

B) Tundra swans were never eaten by bald eagles. There is no arrow connecting them.

D) Wading birds were never eaten by ospreys. There is no arrow connecting them.

The Adam's apple is found in the upper part of the larynx that is formed by the thyroid cartilage.

Hence, option B is correct.

The cartilage that wraps around the front of our larynx, or voice box, is referred to as the Adam's apple or the laryngeal prominence. The name "Adam's" apple may have originated from the biblical account of Adam and Eve, in which Adam consumed an apple, the forbidden fruit, which lodged in his throat. Our voice box and vocal cords are shielded from damage by the Adam's apple, despite the fact that it has little to do with apples.

The Adam's Apple's main purpose is to safeguard the vocal chords directly behind it in both sexes, independent of the angle at which it is viewed. This function is shared by the thyroid cartilage that makes up the Adam's Apple.

The hypothesis must reflect the relationship between the independent and the dependent variables. If a higher amount of baking powder is used to make the cookies, they will rise more because more carbon dioxyde is released.

This is the one the researcher changes to observe how this change affects the response of another variable.

This is the variable that is affected by any change in the independent one. The dependent variable will respond by showing a change in its state.

These are all the remaining variables in an experiment that must be kept under control to avoid a potential effect on the results. Usually, there are several controlled variables and the researcher must keep them stable so they can not influence the dependent variable.

The hypothesis is a prediction about what the researcher thinks might be going on or expects to occur.

It is a claim in which the researcher states a direct and clear relationship between the dependent and the independent variables.

Usually this relationship is a cause and consequence effect, so the way it is usually written is as follows,

"If.... (independent variable), then .... (dependent variable response)"
