Answer:
The correct answer is - eliminates all lymphocytes that have been built that would bind and kill healthy, unaffected body cells.
Explanation:
Self-testing in the immune system is a very important step as it helps in analyzing if the immune cells or lymphocytes. To fight against the intruders, the immune system should initially recognize them. That is, the immune system must have the option to recognize what is nonself (remote) based on what is self. The immune system can make this identification since all cells have distinguishing recognition molecules (antigens) on their surface.
Self-test helps in identifying and eliminate in all lymphocytes that have built and attack the healthy cells and killing them.
In an experiment, a scientist decides to study the effect of exercise on cholesterol levels in people. He studies two set of people—those who exercise every day for an hour and those who don’t exercise at all.
............................ In this case, the statement that people who exercise for an hoour may have lower cholesterol level is HYPOTHESIS. ....................... The cholesterol level would be the DEPENDENT VARIABLE.
An hypothesis refer to a proposed statement based on prior knowledge, which is used as a starting point in scientific experimentation.
In scientific experiments, there are always two variables, independent and the dependent variable. The independent variable is the variable that is changed or controlled in a scientific experiment in order to determine its effects on the dependent variable.
A rabbit breeder has rabbits that exhibit three different coat colors: dark gray, chinchilla (a lighter gray), and albino. When cross breeding rabbits with these different coat colors, he finds that dark gray is dominant to chinchilla and albino, whereas chinchilla is dominant to albino. These phenotypic outcomes indicate that there are more than two alleles of rabbit coat-color genes and that they exhibit
Answer:
Multiple allelism
Explanation:
Multiple alleles occur whereby three or more alternative form of a gene which in this case study are dark gray, chinchilla (a lighter gray), and albino; are all present at a locus but only two of the alleles can be present in just one organism.
Which evidence supports the big bang theory?
A. Planetesimals form in debris disks.
B. Most galaxies are moving toward us.
C. Uniform background radiation is detected in every direction.
D. Galaxies spin faster than they should based on visible matter.
Answer:
The correct answer to the following question will be Option C.
Explanation:
The above given theory seems to be an astrophysical concept of something like the visible universe from those in the early observed times to its corresponding large-scale development. Technical calculations and requirements including its expanding universe of that same universe put the Big Bang between about 13.8 hundred million years ago, which would also be known to be the period of the solar system.So other choices are not related to the given theory. So that Option C would be the appropriate choices.

The diagram shows changes of state between solid,
liquid, and gas. The atoms of a substance lose energy
during a change of state. After the change, the atoms
are close together but are able to slide past one
another.
Which arrow represents the change of state describes above ?
Answer:
Arrow O
Explanation:
The question states that the substance is starting out with high energy (gas) and lowers energy to something that is still able to "slide" or flow, a liquid.
The change is moving from gas to liquid

A population of 40 killer whales lives in a bay that measures 2000 square miles. What is the population density of killer whales?
Answer:
.02
Explanation:
When finding population density, divide the amount of people, animals or things in the region by the total square miles. 40/2000 is .02.
A population is the size of the group of individuals residing at a place. A population of 40 killer whales has a population density of 0.02.
What is population density?Population density is the individual's concentration of a specific species at a particular geographical location. It allows the establishment of the ecosystem and health.
Given,
Number of individulas = 40
Size of the area = 2000
Density = Number of individuals ÷ Size of the area
= 40 ÷ 2000
= 0.02
Therefore, 0.02 is the population density of killer whales.

Gastroparesis is a condition that causes a partial paralysis of the stomach. The stomach has reduced ability to contract to move food through the digestive system. Some common symptoms of gastroparesis are abdominal pain, nausea, and feeling full after eating a small amount of food. What would be the most likely cause of this condition? A. damage to nerves that control the stomach B. lack of pancreatic juices and bile C. lack of enzymes in the small intestine D. damage to the mucus lining of the stomach
Symptoms of this condition include paralysis of the stomach muscles. Muscles are controlled by nerve impulses, therefore the most likely cause for this condition is (A.) damage to nerves that control the stomach
B. lack of pancreatic juices and bile -> this will lead to food not being chemically brokend down properly in the stomach and oils not mixing with water leading to malnutirion
C. Lack of enzymes in the small intestine -> this will also lead to food not being chemically digested and malnutrition

Which statement best describes the cycling of carbon between the atmosphere and geosphere? Precipitation and condensation increasing the groundwater supply Glaciers melting due to an increase in global climate temperatures Volcanic activity releasing carbon into the atmosphere Trees and plants releasing carbon through respiration
Answer:
Volcanic activity releasing carbon into the atmosphere
Explanation:
In the geosphere, carbon enters when the dead and decaying matter takes the form of fossil fuels. From the biosphere, the carbon enters into the geosphere through these sources. A carbon reservoir is maintained in the geosphere through these sources. The process of weathering, erosion, and volcanic eruption exposes the carbon content of the geosphere into the atmosphere. Volcanic eruptions upturn the carbon content of the geosphere and expose them.
Answer:
Volcanic like the answer above

Options are not provided in the questions, so the complete question is as follows:
Which two statements in the passage are true about fungus-like protists?
1) Fungus-like protists feed on decaying leaves.
2) They photosynthesize in the presence of sunlight.
3) They reproduce using spores. They use pseudopods to engulf any foreign material and convert it into food.
4) They are prokaryotic in nature.
Answer:
1) Fungus-like protists feed on decaying leaves.
3) They reproduce using spores. They use pseudopods to engulf any foreign material and convert it into food.
Explanation:
Molds are fungus-like protists and they are heterotrophs like fungi. Slime molds and water molds are well-known example of fungus-like protists. They feed on decaying organic matter such as leaves.
Fungus-like protists reproduce using spore and use pseudopods to engulf any foreign material and convert it into food.

A population of fish has 11,140 individuals. They have a death rate of 100 per year and a birth rate of 120 per year. Assuming 50 fish migrate into the population and 25 migrate out of the population per year, how many individuals would there be after the first year
Answer:
11,185 individuals
Explanation:
The number of individuals after the first year would be 11,185.
The change in the number of individuals in a population or population size is determined by the equation:
(B - D) + (I - E), where B = birth rate, D = death rate, I = immigration, and E = emigration.
In this case, B = 120, D = 100, I = 50, E = 25. Hence, change in the population size;
= (120 - 100) + (50 - 25) = 45
This thus means that the population would have increased by 45 individuals after the first year. Since there were 11,140 individuals initially, the total number of individuals after the first year would be;
11,140 + 45 = 11,185 individuals.
