Humoral immunity is a type of adaptive immunity that results in the circulation of which of the following throughout the blood?
A. antigens
B. macrophages
C. natural killers
D. antibodies
Answer:
Humoral immunity refers to the component of the adaptive immune response that is caused by B cells, antibodies, and type 2 helper T cells (Th2), as well as circulating mast cells and eosinophils to a lesser extent.
Antibodies is circulated throughout the blood in Humoral immunity.
B cells changed into plasma B cells that is responsible for the production of antibodies against a specific microbe such as bacteria and virus etc. The humoral immune system attacks and controls the antigens that are present outside the infected cells. Humoral immunity is also known as antibody-mediated immunity so it is concluded that antibodies provides immunity in humoral immunity system.

Explain the differences in the three types of RNA by connecting it to a factory.
[tex] {\huge{\sf{\green{\underline {\underline {Answer }}}}}} [/tex]
Three major types of RNA are mRNA, or messenger RNA, that serve as temporary copies of the information found in DNA; rRNA, or ribosomal RNA, that serve as structural components of protein-making structures known as ribosomes; and finally, tRNA, or transfer RNA, that ferry amino acids to the ribosome to be assembled .RNA carries genetic information from the nucleus to ribosomes for the synthesis of proteins; while tRNA carries specific amino acids to the ribosomes to assist the protein biosynthesis, and on the other hand, rRNA provides the structural framework for the formation of ribosomes.HOPE IT HELPS YOU.....

Why might it be hard to restore a wildlife population using custodial management?
The restoration of wildlife population under the custodial management is very hard because the wildlife animals are very dangerous to handle and they can harm the normal population.
What is the process of evolution?Evolution is the scientific theory that explains that "a change in the characteristics of biological populations over next generations. According to scientists RNA is the first existing molecule on earth that replicate by itself and the process of evolution lead to advanced forms of life.
The restoration of wildlife population under the custodial management is very hard because the wildlife animals are very dangerous to handle and they can harm the normal population.These characteristics are easily trasffered from one generation to other generation.

How do you think a species population can benefit from being diverse?
Answer:
A species' population that is genetically diverse is more likely to adapt and recover from environmental changes. A genetically diverse population is more likely to possess variations of alleles that are suited for the environment and its changes. Those individuals are more likely to survive to produce offspring bearing that allele.

Which of the following is not a stage in hurricane formation?
A)
Thunderstorms in a low-pressure area combined with the Earth’s rotation cause the storm’s initial rotation.
B)
Pollution in the atmosphere raises the temperature of the air, creating a depression.
C)
Warm, moist air rises from the sea and increases the storm’s energy.
D)
As water from the sea turns into water vapor, latent heat enters the storm, causing the storm’s energy to increase.
E)
As condensation (rain) occurs, latent heat is released, which warms the air and makes it lighter, causing the hurricane to increase in strength and intensity.
Answer:
B
Explanation:
Because if that was the case we would have hurricanes everyday

why does the sodium potassium pump require ATP?
Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

true
Explanation:
the statement is true
A biologist reads an article in a scientific journal that describes how the legs
of different organisms look and function differently, but appear to be
constructed from the same basic bones. He compares a drawing of the
skeletal structure of a porpoise's fin with one of an elephant's leg. (7A)
What aspect of the theory of evolution do these drawings support?
Answer:
Homology
Explanation:
The aspect of the theory of evolution that the drawings support is homology. Homologous organs are organs of different organisms that look similar in structure but perform different functions in reality.
Organs that are built on the same or similar basic plans in the same organisms but perform different functions are thought to have been from the same ancestor. Hence, homology or homologous organ represents one of the evidence used to support the theory of evolution which opines that all living organisms descended with modifications from common ancestors.

How does size influence the appearance of a star? Give an example in your response.
Answer:
when the size of a star increases, luminosity of star also increases.
The color of a star is decided by the surface temperature of the star and the temperature of a star depends on the size of star.
The smaller stars have low temperature and they are usually red (Proxima Centauri - red dwarf star).
The massive stars have higher temperature and they are usually blue (for exaple Zeta Puppis - Blue supergiant star).
