How does specific heat affect the temperature of a body of water whose surface is frozen, but beneath is liquid?
What temperature would the liquid be in comparison to the ice and the air?
Due to its high specific heat capacity, the temperature of the liquid water beneath the ice is higher than that of ice above it.
The temperature of the liquid water will be at 4°C.
What is specific heat capacity of a substance?The specific heat capacity of a substance is the amount of heat required to raise the temperature of a unit mass of that substance by one degree Celsius.
Substances with high specific heat capacity usually require a large amount of heat for the temperature of the substance to be raised or by 1°C.
Water has a high specific heat capacity. Hence water, requires a large amount of heat for its temperature to be raised by 1°C. Also, water being a poor conductor of heat gains as well as loses heat slowly.
Therefore, in frozen body of water, the high specific heat keeps the temperature of the liquid water beneath the ice higher than that of ice.
The temperature of the liquid water will be at 4°C since this is the temperature water is most dense.

Gabe just won the lottery after ten years of consistently buying a ticket every Friday. Based on his initial reaction of feeling joyful, d. cortisol level would most likely decrease within his body.
In the field of science, the cortisol hormone is widely known as the 'stress hormone'. It is the hormone that is constantly released when a person is under stress.
When there is a constant fear or stress situation, the amygdala responds by sending stress signals to the hypothalamus part of the brain. As a result of this, the sympathetic nervous system is activated which is known for fight or flight response. The sympathetic nervous system as a result activates a variety of hormones and systems to overcome stress conditions. The adrenal cortex releases cortisol in response to this continued stress so that the body can stay alert.
As the stress level of Gabe is decreasing due to his joy of winning the lottery, hence the cortisol level is also decreasing in his body.

Suppose that zonosemata flies whose own wings had been clipped and reattached were attacked more frequently than untreated zonosemata flies. How would this result have affected the reliability of the other experimental results?.
Suppose that Zonosemata flies whose own wings had been clipped and reattached were attacked more frequently than untreated Zonosemata flies. All results for the experimental groups involving wing surgery would be invalid.
It has been demonstrated that jumping spiders avoid attacking zonosemata insects because of their mimicking technique. Wings from Zonosemata vittigera were transplanted onto houseflies, and vice versa, as part of the experiment.A wing design that resembles legs and a wing-waving display on the tephritid fly Zonosemata vittigera replicate the aggressive territorial behaviours of jumping spiders. When jumping spiders are stalked by zonosemata flies, the spiders show back and retreat as a result of the display. It has been demonstrated through wing transplant studies that effective imitation requires both the wing pattern and wing-waving displays.The tephritid fly Zonosemata vittigera has dark bands on its wings, which it may wave to avoid predators, particularly scurrying spiders.To learn more about Zonosemata.

Aquaporins c. Diffusion of solutes across the membrane d. Exocytosis of solutes
A raindrop of almost pure water lands on a microbe. Mechanosensitive channels, activated by osmotic pressure, are used by microbes to reduce their internal solute concentration by letting solutes out.
In microorganisms, Mechanosensitive channels are very crucial as they play a significant role in different cellular functions. These channels are triggered by the difference in osmotic pressure in cells.
Different cellular functions performed by them include fluid homeostasis, transfer or expression of genetic information, cell adhesion, cell division, and migration.
Moreover, these channels also make a response to membrane tension by changing their conformation.
As these channels serve as a certain passage for different ions therefore they also activate various cells such as cochlear hair cells, sensory cells, and sensory neurons as a result of force applied to proteins.

A scientist compares the plasma membrane composition of an animal from the mediterranean coast with one from the mojave desert. Which hypothesis is most likely to be correct?.
The cells from the Mediterranean animal will have a low cholesterol concentration in the plasma membranes to the animal from mojave deserts.
The environment is the reason for the validity of this hypothesis. The animal in the Mojave Desert lives in a hot climate, but the animal on the Mediterranean coast lives in a cold climate. The plasma membrane is frequently impacted by temperature because it is composed of phospholipids with a hydrophobic internal fatty acid chain and hydrophilic ends. So, fluid changes inside plasma membranes occur in these ways. The first is the temperature. Plasma membranes will become less fluid as temperatures drop, as the components of the membranes become more firmly packed together. They will normally become more fluid as the temperature rises.
Another consideration is the ratio of saturated to unsaturated fatty acids. Plasma membrane membranes are found in the hydrophobic fatty acid chains. If these fatty acids are saturated, their chains will be straight, and at cooler temperatures, they will compress together limiting fluidity. These chains, however, will have kinks if they are unsaturated. And at lower temperatures, the gaps between these kinks caused by air will keep them fluid. Thus, cholesterol concentration is high in animals of hot temperature because they are not packed but free to move and are saturated.

The cutaneous glands concerned with cooling the body are __________ glands. question 2 options:
a. sebaceous
b. apocrine
c. eccrine
d. ceruminous
e. exothermic
Sebaceous glands are the cutaneous glands concerned with cooling the body. So the correct option is A.
What are sebaceous glands?Sebaceous glands are tiny oil-producing glands found in animal skin. Typically linked to hair follicles, sebaceous glands secrete a fatty substance called sebum into the follicular duct, which subsequently travels to the skin's surface. Excluding the palms of the hands and the soles of the feet, the glands are found all over the body, although they are most prevalent on the scalp and face.
The sebaceous gland releases sebum through the sebaceous duct that connects the gland to the hair follicle, which is a combination of fats (triglycerides, wax esters, squalene, and cholesterol) and cellular waste. Sebum contributes to the formation of the skin's thin, somewhat oily surface coating, keeping the skin flexible and preventing it from absorbing too much water.
