Answer:

The correct answer would be - overpopulation that leads to fewer resources for the population that leads to an increase in death rate.

Explanation:

The carrying capacity of a population is the capacity of an ecosystem to bear up to a definite quantity of a population where the resource and services are present to help in the growing population.

In other words, it is the number of individuals that can be sustained by an ecosystem. If a population exceeds carrying capacity it means there is not plenty of resources available that lead to the competition and ultimately increase in the death rate.

Thus, the correct answer is - increase in the death rate.

Briefly explain the four different types of acid-base disturbance found in the human body

slega [8]

Respiratory acidosis.
Respiratory alkalosis.
Metabolic acidosis.
Metabolic alkalosis

Respiratory acidosis = Respiratory acidosis is a condition that occurs when the lungs cannot remove all of the carbon dioxide the body produces. This causes body fluids, especially the blood, to become too acidic.

Respiratory alkalosis = Respiratory alkalosis is a medical condition in which increased respiration elevates the blood pH beyond the normal range (7.35–7.45) with a concurrent reduction in arterial levels of carbon dioxide. This condition is one of the four basic categories of disruption of acid-base homeostasis.

Metabolic acidosis = Metabolic acidosis is a serious electrolyte disorder characterized by an imbalance in the body's acid-base balance. Metabolic acidosis has three main root causes: increased acid production, loss of bicarbonate, and a reduced ability of the kidneys to excrete excess acids.

Metabolic alkalosis = Metabolic alkalosis is a condition that occurs when your blood becomes overly alkaline. Alkaline is the opposite of acidic. Our bodies function best when the acidic-alkaline balance of our blood is just slightly tilted toward the alkaline.

he x-ray film shows a fracture where one side of the cortex is intact and flexed and the other side has signs of interruption (f

KatRina [158]

Answer:

This is refers to as Greenstick fracture.

Explanation:

This is the type of fracture common in children less than 10 years, in which there is incomplete fracture of the bone,with ,but the cortex remain flexed.It is called green stick because it is analogous to the act of breaking a branch of a tree, which is not completely broken, from the main branch.

It is usually to due to falls,and common in kids because of their soft bones which is not completely formed and therefore will not break off completely like that of adults when fractured, but only from one side only.

There are two properties that affect the conduction speed of an action potential along an axon: die axon's diameter and whether

Rom4ik [11]

Answer:

Axons with high diameter, and myelinated will conduct action potential faster.

Axons with low diameter but myelinated will be relatively slow in the speed of action potential transmission

Axons with high diameter and unmyelinated will be relatively slow in action potential transmission.

Axons with low diameter, and unmyelinated will conduct action potential slowly .

Explanation:

Diameter of Axon affects conduction speed of Action Potential; the thick axons with high diameter conducts action potential at a faster speed than thin neurons. This is because of the less resistance to the transmission of action potential along the thick axon. However, thin neurons with lower diameter has more resistance to the action potential conduct along the axon, thus the speed of transmission is slow.

Myelinated neuron transmits action potential faster because of jumping of action potential at the nodes of Ranvier where there is highest concentration of all channel proteins and pump proteins, Therefore action potential is conducted at a faster rate as it jumps from one node to another. This is salutatory conduction. It increases the conduct about 50 times compare to unmyelinated neuron. In neuron of human it increases the speed to 100ms-1

.Conversely, unmyelinated neurone conducts action potential slowly. About 0.5ms-1 . This is because no salutatory conduction takes place because there is no myelin interruption as Nodes of Ranvier
