Answer:

Option). when blood sugar is too low, the body sends hormones that raise blood sugar until it reaches a typical level and hormone secretion slows.

Explanation:

In a negative feedback loop can be defined as a self-regulating system, in which the increased system output of prevents further production by the system.

For example, regulation of hormone glucagon. Glucagon is produced by pancreatic cells, when blood sugar level is too low. The glucagon raises level of blood sugar by producing glucose from glycogen and other complexes.

When cells detect increased level of sugar in blood, secretion of glucagon form pancreatic cells slows down and then stops to inhibit further release of hormone.

Thus, the correct answer is third option.

Which molecule is less soluble in water--a fat or a phospholipid? Why?

VladimirAG [237]

Fat is less soluble in water compared to phospholipids.
This is because, fat is made up of three molecules of fatty acids which are not polar in nature at all, thus they mixed very poorly with water.
Phospholipids on the other hand has its molecules divided into two distinct regions, the head and the tail region. The head region is hydrophillic and it is polar in nature, that is, it mixes well with water. The tail region is made up of the fatty components and it is hydrophobic.
Because of this difference in structure, phospholipid will dissolve better in water.

Explain the difference between afferent and efferent neurons.

natka813 [3]

Answer:

<h3>The Difference between Afferent and Efferent Neurons :- </h3>

Neurons that receive information from our sensory organs (e.g. eye, skin) and transmit this input to the central nervous system are called afferent neurons.

Neurons that send impulses from the central nervous system to your limbs and organs are called efferent neurons.
