The ellipse becomes a circle when the eccentricity is 1.

The eccentricity (e) of an ellipse can be determined using the formula:

e = c/a

where c is the distance between the center of the ellipse and each focus, and a is the semi-major axis of the ellipse.

In the given scenario, we are told that one focus is 10 cm away from another, which means c = 10 cm. Since both foci rest on the ellipse, the distance between them is equal to the length of the major axis (2a).

Therefore, 2a = 2c = 20 cm.

Now, we can substitute the values into the formula to calculate the eccentricity:

e = c/a = 10 cm / (20 cm / 2) = 10 cm / 10 cm = 1

Hence, the eccentricity of the ellipse in this scenario is 1.

An eccentricity of 1 indicates that the ellipse is actually a special case of a circle, where both foci coincide at the center. In other words, the ellipse becomes a circle when the eccentricity is 1.

The process that is not common during the post-absorptive state is glucose catabolism.

The post-absorptive state, which is also known as the fasting state, refers to the period after food consumption has ceased. During the post-absorptive state, energy must be derived from stored macronutrients in order to maintain blood glucose levels and support other physiological processes. Glucose catabolism is a process in which glucose is oxidized in order to produce energy, which is utilized to carry out cellular processes.

This process typically occurs in the presence of oxygen, and is known as aerobic respiration. In the post-absorptive state, glucose levels decrease and the body relies on alternative sources of energy, such as fatty acids and ketone bodies, which are produced via ketogenesis. Thus, glucose catabolism is not common during the post-absorptive state as glucose levels are low and the body must rely on other sources of energy.

Like many insects, some amphibians undergo Metamorphosis in their life cycle as they have distinct larval and adult stages.

Metamorphosis is a process by which many insects and some amphibians undergo transformation in their life cycle.

During metamorphosis, the organism goes through distinct physical changes that alter its form and physiology, leading to the development of different life stages.

In amphibians, metamorphosis involves the transformation from a water-breathing, herbivorous tadpole larva to an air-breathing, carnivorous adult with four legs and a tail. This process involves the loss of the tail, gills, and the development of lungs, limbs, and other organs necessary for life on land.

In summary, metamorphosis is a crucial process in the life cycle of many insects and some amphibians that enables them to adapt to different environments and ecological niches.

In the case of amphibians, metamorphosis leads to the development of adult forms that are adapted to life on land, enabling them to survive and thrive in diverse habitats.

The major factor for setting long-term blood pressure is blood volume.

E is the correct answer.

Blood volume is a crucial element in the long-term control of cardiac output and blood pressure. Long-term blood pressure management depends on the homeostatic regulation of blood volume.

The quantity of water and sodium ingested, excreted by the kidneys into the urine, and lost through the digestive system, lungs, and skin determines blood volume. The quantities of sodium and water that are consumed and excreted vary greatly.

Vascular collapse, decreased pressure, and eventually decreased perfusion pressure are all caused by a decrease in blood volume. By tightening blood vessels until the body achieves a blood pressure that restores proper perfusion pressure, the cardiovascular system combats low blood volume.

After an animal dies, rigor mortis occurs due to the depletion of ATP (adenosine triphosphate) in the muscle cells. ATP is necessary for muscle contraction and relaxation.

When ATP levels decline, certain changes occur in the muscle cells. Among these changes, the lack of ATP directly causes an inability for the myosin head to bend.

During muscle contraction, myosin heads bind to actin filaments and undergo a conformational change, resulting in the sliding of the filaments and muscle contraction. This bending of the myosin head is powered by the hydrolysis of ATP. Without ATP, the myosin heads cannot undergo the necessary conformational change, leading to a loss of muscle movement and muscle stiffness characteristic of rigor mortis.

Therefore, the lack of ATP in the muscle cell directly causes an inability for the myosin head to bend, resulting in the muscle stiffening observed during rigor mortis.

Water is transported into and through a plant through a process called transpiration.

It starts with the absorption of water from the soil through the roots of the plant. The water is then transported through the xylem, which is a specialized tissue that runs throughout the plant, from the roots to the leaves. As the water moves through the plant, it evaporates from the leaves, creating a negative pressure that pulls more water from the roots into the plant.

It is aided by the opening and closing of stomata on the leaves, which regulate the amount of water that evaporates from the plant. The process of transpiration is crucial for the survival of the plant, as it allows the plant to transport water and nutrients from the soil to the leaves, where they are used for photosynthesis and other metabolic processes.
