A young patient is short in stature, with his limbs and trunk in proportion. His mental development appears to be appropriate for his age. Determine and discuss the type of hormonal disorder he likely has.

Answers

Answer:

Dwarfism

Explanation:

Dwarfism is a growth disorder characterized by a height that is much lower than the average for people of the same race and age. Individuals with proportionate dwarfism have excessively short bodies but the dimensions of all their parts are proportionally smaller. It is due to certain diseases that are already present at birth or that manifest themselves during early childhood, and that block the normal development of their body, such as the deficiency or deficit of growth hormone is when there is not enough hormone growth released by the pituitary gland. Dwarfism does not directly lead to a deficiency in the intellectual capacities of the individual, in general their mental development is normal.

Darker skin in equatorial environments is adaptive because it prevents ____________ deficiencies, which cause _____________ in newborns.

Answers

Answer:

Vitamin D

Rickets

Explanation:

Lack of vitamin D causes rickets

Darker skin in  equatorial environments is adaptive because it prevents  vitamin D deficiencies, which cause Rickets in newborns.

What determines skin color?

The pigment melanin is by far the most important factor that determines the color of people's skin, although there are many other factors that play a role. People with darker skin have more melanin, which is the primary pigment responsible for their skin color. Melanocytes, which are cells found in the skin, produce melanin.

People who live closer to the equator typically have darker skin as a form of protection against the sun's ultraviolet (UV) rays. This is because excessive UV exposure can lower folic acid levels and lead to skin cancer.

Black people have more melanin in their skin than people with lighter skin, which affects the body's ability to synthesize vitamin D. People with lighter skin have less melanin in their skin.

Therefore, near equator more sunlight causes increased vitamin D production , preventing rickets in new born.

David Tilman's study of two diatom species, each with differing abilities to utilize different levels of multiple resources, showed that coexistence is only possible when both resource levels are high. coexistence is only possible when both resource levels are low. coexistence is not possible. coexistence is possible if each species is more efficient at using a different resource than the other species.

Answers

Answer:

coexistence is possible if each species is more efficient at using a different resource than the other species.

Explanation:

Competition is an ecological and evolutive process very common in nature. Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use, or the same territory, shelter, etcetera. When a resource is useful for two or more species, and limited, they compete to gain it.

The principle of competitive exclusion states that different species with the same requirements sharing the niche can not coexist indefinitely based on the same limited resource. When two competing species coexist, this is because of niche partitioning or niche differentiation.

Differentiation of effective niche is closely related to character displacement.

Character displacement is the result of interspecific competition, in which two or more species that live in the same habitat manage to avoid competition by developing different traits. Morphological divergence, or any adaptative trait development, fixated genetically, is the product of niche segregation. Species tend to differentiate morphologically in the presence of strong competitors. Traits divergence favors coexistence in the same place.

In the exposed example, both species have different abilities to utilize different levels of multiple resources. If both species live in the same place, this ability is significant to avoid competition and competitive exclusion.

A patient with osteoporosis (reduced bone mass) may have a history of health issues. One issue could be
not enough skin exposure to the sun to make Vitamin D.
weak ligaments.
an increase in the absorption of calcium in the digestive system.
weak tendons.

Answers

Answer:

not enough skin exposure to the sun to make Vitamin D.

Explanation:

The correct answer would be not enough skin exposure to the sun to make Vitamin D.

The body makes vitamin D by being exposed to the sun and this vitamin and its metabolite are quite important in the homeostasis of calcium. Calcium on its own is very essential to the formation of bones in the body.

Hence, when the skin is not adequately exposed to the sun, the body becomes short of vitamin D and this disrupts the homeostasis of calcium and the formation of bones in the body. Thus, osteoporosis, also known as weak bones, may result.

Answer:

(A) not enough skin exposure to the sun to make Vitamin D.

Asexual reproduction differs from sexual reproduction in that Group of answer choices asexual reproduction utilizes DNA from two parents to code for traits in offspring. asexual reproduction occurs only in plants. asexual reproduction produces offspring containing DNA from only one parent. asexual reproduction only occurs in animals. asexual reproduction produces genetically diverse offspring.

Answers

Answer:

Asexual reproduction produces offspring containing DNA from only one parent.

Explanation:

Asexual reproduction produces offspring containing DNA from only one parent because in asexual reproduction, the organisms born or produced from a single parent. The offspring is identical to their parent and this process of asexual reproduction occurs in both plants and animals. Asexual reproduction produces identical not genetically diverse offspring in the end of the process.

Answer:

Because asexual reproduction results in the birth or creation of organisms from a single parent, the children created have DNA from just one parent. Both plants and animals can reproduce asexually, and the progeny are identical to their parents. Asexual reproduction ultimately results in identical, not genetically different, offspring.

Answers

Answer:

Oxygen.

Explanation:

Oxygen is the gas that is increased in concentration due to photosynthetic activities of plants and algae because in the process of photosynthesis, plants and algae absorb carbondioxide gas into the body and as a result, oxygen gas is produced. Some amount of oxygen is used by the plants in the process of respiration while the remaining is released in the atmosphere through stomata.

Extinction is defined as the disappearance of an organism or a group of organisms as a result of environmental factors or changes in the members' evolutionary processes.

It can also be defined as an evolutionary process that causes a species or population to go extinct.

When there are no longer any living members of a certain animal or plant species anywhere in the globe, the species has become extinct.

Generally speaking, species disappear for the following reasons:

Genetic and demographic phenomena.Habitat destruction in the wild.Species introduction that are invasive.Global warmingHunting and illicit trade.

The pie chart indicates that deforestation in the Amazon rainforest is mostly driven by food production. The loss of large carbon-storing trees combined with the presence of methane-producing cattle is likely to intensify greenhouse gases in the Amazon.

What is deforestation in the Amazon rainforest?

Deforestation in the Amazon rainforest has significant environmental consequences. Trees store large amounts of carbon dioxide, and their removal contributes to increased greenhouse gas emissions, which are a major cause of climate change. Additionally, the cattle that are raised on cleared land produce methane, which is another potent greenhouse gas. As more trees are cleared to make way for agriculture and cattle farming, the carbon storage capacity of the forest is reduced, and more methane is released into the atmosphere.

Hence, the pie chart indicates that deforestation in the Amazon rainforest is mostly driven by food production. The loss of large carbon-storing trees combined with the presence of methane-producing cattle is likely to intensify greenhouse gases in the Amazon.
