A.
volume increases and density decreases
B.
volume decreases and density increases
C.
volume increases and density increases
D.
volume decreases and density decreases
Answers
Answer:
The answer is A, Volume increases and density decreases
Explanation:
When water is cooled from 4°C to 0°C, the volume of water increases and density decreases. Thus, the correct option is A.
What is the Density of water?The density of water may be defined as the weight of the water per unit volume, which depends on the temperature of the water. The normal density of water is 997 kg/m³.
When the temperature of liquid goes down, the density of its gradually decreases, as a result of this, the volume considerably increases.
Therefore, the correct option for this question is A.

Cell Membrane
Answers
The organelle that controls what goes in and out of the cell is the cell membrane, which is present in the second option. The cell membrane is the outer protective layer of the cell that does this function.
What is the role of the cell membrane?The cell membrane is the membrane that acts as the selective barrier for the cell, and through it, substances can enter and exit the cell. When energy is spent for the molecule to move, it is referred to as active transport; when it is not spent, it is referred to as passive transport.
Both eukaryotes and prokaryotes, as well as fungi, have different cell membrane compositions; some have more lipid content, some have less, some have cholesterol, and some don't. The lipids and proteins are arranged in such a way as to maintain cell homeostasis.

Why?
B
Which air pocket would you expect to cool down more at night
Answers
Answer:
The wind moves from regions of lower air temperature to regions of higher air temperature because of a pressure differential set up by the two air masses
Explanation:
Relationship between wind speed and direction to air temperature:
wind flows from regions of lower air temperature to regions of higher air temperature because of a pressure differential set up by the two air masses.
A. The land air will heat up more during the day. This is because the land has a lower specific heat capacity than water, hence increases a lot more rapidly in temperature than the sea when the sun comes up.
B. The air packet over the land will cool down more rapidly at night due to the lower specific heat capacity of land when compared to the sea.

lipid production; increases in liver cells as a response to regular alcohol or barbiturate consumption
Answers
Answer: Lipid production occurs at slower rate.
Explanation:
The ethanol or ethyl alcohol is a hepatotoxic which involves the redox changes in the NADH that results due to the oxidation of the alcohol dehydrogenase enzyme. It affects the metabolism of the lipids, amino acids, carbohydrates and proteins in the body. As the liver cells get engaged in metabolism of regular alcohol or barbiturate. The liver cells get damaged in this process. The ethanol is metabolized into acetaldehyde. So, the lipid production as a metabolite occurs at a slower rate.
How does the lipid portion help maintain water concentration on each side of the bilateral?
Answers
Answer:
Explanation:The phospholipid bilayer formed by these interactions makes a good barrier between the interior and exterior of the cell, because water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane. Can water cross the plasma membrane at all?
It also helps the cell move things in and out. The cell membrane is made of what is called a phospholipid bilayer, which means it has two layers of phospholipids. ... This allows the phosphates to be exposed to water, either in the cell or the environment, while the lipids are protected from water Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.Large quantities of water molecules constantly move across cell membranes by simple diffusion, often facilitated by movement through membrane proteins, including aquaporins. In general, net movement of water into or out of cells is negligible.

Answers
Answer:
The correct answer is - A patient's own tissue - an autograft and tissue from another person - an Allograft.
Explanation:
If the bone or the tissue is transferred from one point of the body to another point of the same person's body, this is called an autograft and is also thought of as "gold standard". It has a low level of risk in comparison to other grafts. It is used for surgical reconstruction.
An allograft is the transfer of the tissues or bone of an individual to the body of another individual of the same species during the surgical process. This type of graft has some risk of compatiblity.

When resources are stable over a long period of time, a species' population can be expected to
O die out.
o increase.
O stay the same.
O decrease.
Answers
In an environment with stable availability of resources, the population can still grow because there are enough resources for this population to survive. Option B. The species' population can be expected to increase.
This question is related to growth models.
Logistic growthA growing population that inhabits a limited space is gradually affected by density, rebounding in the multiplication rate.
The population growth per capita rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
Carrying capacityCarrying capacity refers to the maximum point at which the environment can support a growing population.
K is a constant. It coincides with the population size when natality rate and mortality rate are equal to each other. This is the equilibrium point.
• If the population size, N, is inferior to K (N<K), the population can still grow.
• When N approximates to K, the population´s growth speed decreases.
• When N=K, the population reaches equilibrium,
• When N is superior to K (N>K), the population must decrease in size because there are not enough resources to maintain that size.
So when the population size exceeds K, carrying capacity makes the population decrease in size.
But if there is a constant availability of resources, the population can still grow because there are enough resources for this population to survive. In this situation, N<K.
When resources are stable over a long period of time, a species' population can be expected to INCREASE. Option B.
