These clinical findings are best explained by dysfunction in which of the following regions of the nervous system?A. anterior horn cellB. muscleC. nerve plexusD. peripheral nerveE. spinal cord

Answers

Answer:

spinal cord and nerve plexus

Explanation:

Faced with this clinical picture, we would be talking about the affection of the spinal cord and the peripheral nerves that sensually perceive the areas of the epithelium, that is, they give the sense of touch, since the patient is diabetic, it could be deduced that the microangiopathies that this generates Chronic disease over time, can affect the irrigation of certain areas and therefore their inventions, due to lack of supply of oxygen and nutrients.

Diabetics are at risk of affecting both upper and lower limbs, because over time they lose the vascularization and winterization of these areas, thus generating infections or pain imperceptible by the patient.

On the other hand then, it would be ideal to say that the spinal cord with the peripheral nerves that innervate the affected areas, and the cerebellum are affected by the lack of balance or spatial disposition of the patient in relation to their body size.

Which of the following accurately describes nutrient limitation?a. Nitrogen is typically the limiting nutrient in freshwater environments.
b. Soil environments aren't affected by nutrient limitation.
c. If one essential nutrient within an ecosystem runs out, primary productivity will be limited.
d. Limiting nutrients are the nutrients whose supply is in excess.

Answers

Answer is c. If one essential nutrient within an ecosystem runs out, primary productivity will be limited

According to Vitousek et al., 2010, nutrient limitation defined as meaningful additions of an essential element in biologically available forms which increases the rate of primary productivity or increase in the biomass in an ecosystem. Alternately, nutrient limitation may also explained as when the supply of one essential nutrient of the ecosystem runs out the primary productivity of the plants will be limited.

Final answer:

Nutrient limitation refers to a situation where an ecosystem or organism's growth is hampered due to lack of a certain essential nutrient. When such a nutrient runs out in an ecosystem, primary productivity is affected as this nutrient is vital for the growth of primary producers.

Explanation:

Nutrient limitation describes a situation in which the lack of a particular essential nutrient prevents an organism or ecosystem from reaching its full growth potential. This concept is very essential in the area of ecology. The correct answer to your question is (c.) 'If one essential nutrient within an ecosystem runs out, primary productivity will be limited.' Let's consider primary productivity in a freshwater ecosystem for example. It is often limited by the availability of nutrients like nitrogen or phosphorous. When these nutrients run out, primary productivity is affected because these nutrients are essential for the growth and development of primary producers (like plants), which set the foundation for energy flow in an ecosystem.

Answers

We design a model that explains how your experiment demonstrated the transfer of genetic material from father to offspring. In our model, we clearly identify where the transfer of genes from parents to children took place, and in this practical way, we explain heredity.

Transmission of genetic information

Heredity is the biological system of transmission of certain characteristics of living beings between generations. For the full functioning of this structure, genes are needed – a piece of DNA (deoxyribonucleic acid) that houses genetic information.

Some properties can remain inactive for generations, which does not represent their extinction, only the forgetting of one or several genes. However, this does not make it impossible for the carrier of the dormant gene to pass it on to their descendants.

In addition, genetic information is capable of disappearing as a result of environmental and climate change. In these cases, natural selection processes directly affect heredity.

With this drawing, it was possible to visualize how gene transfer occurs in a normal situation.
