Explanation:
Answer:
A group of disorders that cause red blood cells to become misshapen and break down.
Explanation:
With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape. The cells die early, leaving a shortage of healthy red blood cells (sickle cell anemia), and can block blood flow causing pain (sickle cell crisis).Infections, pain, and fatigue are symptoms of sickle cell disease.

Hydras are animals related to coral and jellyfish. Hydras can reproduce sexually or asexually. Why would hydras avoid reproducing asexually when conditions are difficult?
1. The high genetic diversity could mean that all of the hydras die, depending on the situation.
2. The lack of genetic diversity could mean that all of the hydras die, depending on the situation.
3. Reproducing more slowly would be a good way to take advantage of plentiful resources.
4. Reproducing more rapidly would be a good way to take advantage of plentiful resources.
Answer: 3. Reproducing more slowly would be a good way to take advantage of plentiful resources.
Explanation:
Hydra reproduce by both sexual and asexual modes of reproduction. In the case of asexual reproduction the bud develops on the parent body and derives nutrition from parent body, matures and finally get detached from the parent body. During asexual reproduction many buds will develop and live as an individual organism this will reduce the availability of resources like habitat, food, and others. Thus if the organism reproduces slowly then it will take advantages of many resources without experiencing the scarcity of resources.

What does a high population density indicate?
O The area is being overfished.
O The species is likely to face extinction.
O There is no other place for that species to live.
O Food supply is high and the number of predators low.
Answer:
O Food supply is high and the number of predators low.
Explanation:
Population density is defined as the population living in per square mile/km.
High population density indicate that the people living in an area have high food supply and the number of predators low. Predators are responsible to control the population but due to high food supply and low predators, there will be no control in the population and no control in the feeding behavior of the population that leads to High population density.
Hence, the correct option is "Food supply is high and the number of predators low."
Answer:
D; Food supply is high and the number of predators low.

In 1907, Dr. Duncan MacDougall performed a series of experiments in which he attempted to measure the weight of the soul as it left a dying person. In his experiments, MacDougall placed a dying person on a scale and measured their weight immediately prior to and following death. MacDougall determined the change in weight to be approximately 21 grams. From these experiments, he concluded that the soul exists and has mass. What is the fundamental scientific flaw in his conclusions? (5 points)
They are based on the concept of the soul, which is beyond the bounds of science.

Which of the following best describes how the structure of the fluid mosaic model of the cell membrane controls the movement of substances in and out of the cell? (3 points)
Answer: The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components —including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. Plasma membranes range from 5 to 10 nm in thickness.
Explanation:
The option that describes the fluid mosaic model of the plasma membrane is a lipid bilayer with protein molecules dispersed within it.
It should be noted that the fluid mosaic model of the plasma membrane was proposed by Singer and Nicholson to explain the structure of the plasma membrane.
The plasma membrane is known as a fluid model because it has several types of molecules that float along the lipids. The fluid mosaic model of the plasma membrane is made up of two layers of lipid molecules where there are protein molecules dispersed within.
