Explanation:
Carbohydrates are organic molecules composed of carbon, hydrogen and oxygen. Carbohydrates can be classified into three types: monosaccharides (e.g. glucose), disaccharides (e.g., lactose), and polysaccharides (e.g., starch). Cellulose is a carbohydrate where many glucose rings chain together, while chitin is a polysaccharide consisting of chains of modified glucose molecules.
Lipids represent a diverse group of organic molecules that include, among others, fats, waxes, oils, hormones, etc. Lipids play a role by insulating (and protecting) the body. For example, there is a layer of fats beneath the skin which enables to maintain body temperature relatively constant. In animals, lipids constitute about 50% of the mass of cell membranes. These membrane lipids are mainly phospholipids, glycolipids and cholesterol. There are hormones that derive from lipids such as steroid hormones, which derive from cholesterol. Some examples of steroid hormones are testosterone, estrogen and cortisol.

In North America, many top predators, such as wolves, have been driven nearly to extinction. What effect do you think this has on their main prey, deer? Write your answer below, and discuss with your classmates.
Extinction refers to the elimination of species or groups of organisms due to human-made causes or natural events.
In North America, animals or predators such as wolves have been extinct that can affect the food chain and their prey.
The wolves in North America grew in number to such an extent that government and wildlife agencies developed the rules and regulations to hunt down and kill the wolves, which led them to near extinction.
Wolves feed or attack the deer and are a type of parasitism relationship. In this relationship, wolves are benefitted and deer are harmed.
The extinction of wolves will be led to an increase in the deer population, as deers are the prey and will have no fear from the wolves.
Thus, the deer population will increase in number.

Name and describe the five types of active transport systems.
Answer:
Please Mark as Brainliest. Please!!!!!!!!!!
Explanation:
Definition
Active transport is the process of transferring substances into, out of, and between cells, using energy. In some cases, the movement of substances can be accomplished by passive transport, which uses no energy. However, the cell often needs to transport materials against their concentration gradient. In these cases, active transport is required.
Active transport requires energy to move substances from a low concentration of that substance to a high concentration of that substance, in contrast with the process of osmosis. Active transport is most commonly accomplished by a transport protein that undergoes a change in shape when it binds with the cell’s “fuel,” a molecule called adenosine triphosphate (ATP).
For example, one type of active transport channel in the cell membrane will bind to the molecule it is supposed to transport – such as a sodium ion – and hold onto it until a molecule of ATP comes along and binds to the protein. The energy stored in ATP then allows the channel to change shape, spitting the sodium ion out on the opposite side of the cell membrane. This type of active transport directly uses ATP and is called “primary” active transport.
Another type of active transport is “secondary” active transport. In this type of active transport, the protein pump does not use ATP itself, but the cell must utilize ATP in order to keep it functioning. This will be explained in more depth in the section on Symport Pumps below.
Lastly, active transport can be accomplished through processes called endocytosis and exocytosis. In exocytosis, a cell moves something outside of itself in large quantities by wrapping it in a membrane called a vesicle and “spitting out” the vesicle. In endocytosis, a cell “eats” something by wrapping and re-forming its membrane around the substance or item.
Each type of active transport is explained in more detail below.
Types of Active Transport
Antiport Pumps
Antiport pumps as an example of active transport
Active transport by antiport pumps
Antiport pumps are a type of transmembrane co-transporter protein. They pump one substance in one direction, while transporting another substance in the opposite direction. These pumps are extremely efficient because many of them can use one ATP molecule to fuel these two different tasks.
One important type of antiport pump is the sodium-potassium pump, which is discussed in more detail under “Examples of Active Transport.”
Symport Pumps
Symport pumps take advantage of diffusion gradients to move substances. Diffusion gradients are differences in concentration that cause substances to naturally move from areas of high to low concentration.
In the case of a symport pump, a substance that “wants” to move from an area of high concentration to low concentration down its concentration gradient is used to “carry” another substance against its concentration gradient.
One example of a symport pump – that of the sodium-glucose transport protein – is discussed below under “Examples of Active Transport.”
Sympoter pump as an example of active transport
Active transport by symporter pumps
Endocytosis
In the third type of active transport, large items, or large amounts of extracellular fluid, may be taken into a cell through the process of endocytosis.

During the summer the wind blows from the south west so it will blow toward the land.
What is summer?One of the four seasons is summer. The summer months are the warmest of the year. Summer can be the wettest (and rainiest) season in some regions while being a dry season in others.
In regions that are neither too hot nor too cold, there are four distinct seasons. Summer arrives on Earth's north and south poles at diametrically opposed times of the year.
Summer occurs between the months of June and September in the northern hemisphere and between December and March in the southern hemisphere. This is because the south of the Earth always faces away from the Sun while the north always faces the Sun.
Therefore, During the summer the wind blows from the south west so it will blow toward the land.

Small insects can walk across the surface of calm water.
Their feet push the surface of the water down slightly,
somewhat like a person walking across a trampoline, but
they do not break the surface. What is the best
explanation for why this happens?
A. The insects are light enough so that they do not break the hydrogen bonds holding the water molecules
B. The insects actually use their wings to hover slightly above the waters surface and they only skim it with their feet
C. The insects feet are non- polar so they are repelled by the polar water molecules and are pushed away from the waters surface
D. The insects are small enough to see the individual water molecules so they are able to step carefully from one molecule to the next
Answer:
A. Insects are light enough so that they do not break the h bonds holding the water molecules together
Explanation:
The insects are light enough so that they do not break the hydrogen bonds holding the water molecules when they walk across the surface of calm water their feet push the surface of the water down slightly and it is due to surface tension.Thus, option A is correct.
What is surface tension?Surface tension is the tendency of liquid surfaces at rest to shrink into the minimum surface area possible.
Surface tension is responsible for the shape of liquid droplets and the surface tension of water is about 72 mN/m at room temperature.
Water has a tremendous amount of surface tension due to which small mass distributed effectively on its surface.
Surface tension is represented by the symbol T.

A Dysfunctional checkpoints may lead to abnormal cell growth.
B Defective checkpoints result in death of a cell.
C Normal checkpoints assess damage to cancer cells.
D Cell checkpoints fail only in meiosis.
What would this be.
Answer:
A Dysfunctional checkpoints may lead to abnormal cell growth.
Explanation:
One of the hallmarks of cancer is unregulated cell proliferation. This means cells keep dividing, producing large numbers of often abnormal cells.
There are many of ways this can happen, such as increased signals telling the cells to divide, and dysfunctional cell cycle checkpoints that do not stop the cell from dividing. This leads to the accumulation of mutations and abnormal cell growth.

A. releasing H+ to a solution when acids are added.
B. donating H+ to a solution when bases are added.
C. accepting H+ from a solution when acids are added.
D. both donating H+ and accepting H+.
Answer:
Buffers are substances that help resist shifts in pH by both donating H⁺ and accepting H⁺ (option D).
Explanation:
A buffer is a chemical substance capable of balancing the pH of a solution, when the balance is altered by the addition of an acid or a base. They are also called cushioning solution, and can be formed by an acid and its base conjugated, with a specific range of action.
The presence of a buffer in a solution has the ability to release hydrogen ions (H⁺) or accept them, helping to balance the pH, in the presence of a base or an acid, respectively. That is, a buffer can yield H⁺ to a solution when there are few or accept H⁺ when its content is high.
The other options are not correct because:
A. Buffers do not release H+ into a solution when acids are added, but accept them.
B and C. Giving up H+ to a solution when bases are added or accepting H+ from a solution when acids are added are effects that buffers can potentially do, which is described in the text above.

Answer:
Because evolutions don't happen overnight, it takes years and years for an organism to develop an evolution. So, the earth has to be old, because if we look at the earth when it was young, then we don't really see any evolutions.

Explanation:
It really depends on how the question is phrased. Animals and plants that are unable to adapt to their enviroment will become- Hold it right there. How long will they be unadaptable? Is this forever? If so then yes, they will definately become extinct. If this is for a short amount of time then no, they will become prey, but there is also the fact that yes, they will become hungry. Because if they are not adapted then how are they gonna know the best sports for grub? Same thing for plants, if they can't adapt to the climate, they cannot produce food for themselves. Basically, if its a simple question then forget about everything else. It's Prey, because animals that can't adapt to their enviroment are immedietly in danger. Now if this question has more to it then I would go for C. But overall Just go with prey for now.
