Which of these
describes
humoral immunity?
A. the binding of antigen and antibody triggering a response of
plasma and memory b-cells to attack
B. t-cells and macrophages fighting infected cells that are non-self
or cancerous
C. our body remembering pathogens it has fought off or learning
from vaccines
D. obtaining immunity from an outside source, like mother to baby
Answers
According to the research, the binding of antigen and antibody triggering a response of plasma and memory b-cells to attack describes humoral immunity.
What is humoral immunity?It is the immune response mediated by specific antibodies designed to eliminate extracellular pathogens and prevent the spread of intracellular ones.
Antibodies are specific proteins synthesized by plasma cells, the immediate progenitors of these cells are memory b-cells that are capable of reacting with foreign molecules to the body, called antigens.
Therefore, we can conclude that according to the research, the binding of antigen and antibody triggering a response of plasma and memory b-cells to attack describes humoral immunity.

Answers
Answer:
warm: gentle long lasting rain , half red circles, slides over the top of air masses
cool: blue triangles, force existing air into atmo., heavy storms
Explanation:
Gentle, long-lasting rain, sliding over the top of existing air mass and shown as red half circles on the map was an indicator of warm fronts whereas heavy storms, forcing existing air up into the atmosphere and shown as blue triangles on the map are indicators of cold fronts.
What are warm fronts?A warm front occurs when warm air mass overtakes colder air mass while moving forward resulting in the production of precipitation, clouds, or thunderstorms. A light rain or drizzle is also a result of warm fronts.
A cold front occurs when a cold air mass undercuts a warm air mass while moving forward. when the warm air is lifted by colder air, it causes clouds to condense resulting in thunderstorms, or even tornadoes. Severe weather accompanied by strong winds and low temperatures was created by cold fronts.
Warm fronts bring gentle, long-lasting rains, slide over the top of the existing air mass, and are shown as red half circles on the map whereas cold fronts bring heavy storms, forcing existing air up into the atmosphere, and shown as blue triangles on the map.
Therefore, warm fronts bring gentle and long-lasting rains, whereas cold fronts bring heavy storms.

Magnetic fields on the sun are produced by the sun’s uneven rotation and:
A. The movement of sunspots on the sun’s surface.
B. The movement of gases in the corona.
C. Gases in the convective zone.
D. Gases in the radiation zone.
Answers
Answer:
The correct answer is - C. Gases in the convective zone.
Explanation:
The heat of the sun causes the atoms to be ionized and create a charged gas known as plasma. These gases or plasma are move in the convective zone with the uneven and rapid rotation of the sun.
This creates the electric currents due to the charge in gases which ultimately create magnetic fields. Sun's rotation causes the sun's overall magnetic field to have some degree of order and to be somewhat stable over time.

Fruit trees in a forest are an important habitat for a bird species and were historically a major source of food for a rodent species. Over time, the rodent species shifted their feeding behavior from fruit trees to nut trees. As rodent behavior changed, the density of fruit trees decreased, which caused significant decreases to the bird population. What kind of effect did the change in rodents exert on bird population size?
Answers
Answer:
The bird population might have to migrate in search for food or may decline in numbers.
Explanation:
This is a concept of primary producers that is trees and secondary consumers that is mouse and bids. Due to the decline in raw material available the mouse population declines and this also affects the secondary consumers that are birds of prey like hawks, owls etc.what are the cells that pass from parents to their children

Explanation:
Higher plants, lower plants (mosses) and ferns undergo a life cycle called ALTERNATION OF GENERATIONS. In this life cycle, they switch between a haplontic and diplontic forms of life.
The haplontic (haploid) life form which produces haploid (n) gametes is called GAMETOPHYTE while the diplontic (diploid) life form which produces the spores that germinates is called SPOROPHYTE. Hence, sporophyte and gametophyte are two different forms a plant can have.

Which relates the wavelength and frequency of a wave?
The frequency is the number of wavelengths that pass a fixed point in a second.
A wavelength is the distance on a wave between one frequency and the next.
The time it takes for one wavelength to pass a fixed point is the frequency.
The speed at which a wavelength travels is the frequency of the wave.
Answers
Answer:
The correct answer is - The frequency is the number of wavelengths that pass a fixed point in a second.
Explanation:
The wavelength of a wave is the distance between one point on a wave and the nearest point or one crest to another crest of a wave. The frequency of the wave is the number of wavelengths that pass a fixed point in a second. A period is the amount of time one wavelength requires to pass a point.
Frequency = 1/wavelength, which means if one increases other decreases.
Thus, the correct answer is - The frequency is the number of wavelengths that pass a fixed point in a second.

Cell specialization is important during the growth and development of
a multicellular organism. This process is most directly regulated by
Answers
Answer:
Protein
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms.
Cell specialization is also referred to as cell differentiation and it can be defined as a biological process through which generic cells transform into specific cell types, so as to enable them perform certain functions within the body of a living organism.
Simply stated, it's the special function or job in the body of a living organism that are associated with cells.
Generally, cell specialization plays a significant role in the development of embryos.
Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cell specialization is fundamental and key for the growth and development of a multicellular organism.
Furthermore, cell specialization as a process is most directly regulated by protein; one super regulating protein encourages cell differentiation while the other tries to stop or prevent the process. These proteins are referred to as master regulating proteins or Helix-Loop-Helix proteins.

Answers
Answer:
Aerobic metabolism of amino acid requires deamination
Explanation:
Living system can be defined as the internal systems of organisms and how materials circulate within organisms.
Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.
Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.
Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc., which are typically used for carrying out various bodily functions such as respiration, digestion, metabolism, etc.
Metabolism can be defined as a set of chemical processes carried out by a living organism such as humans, plants and animals, in order to sustain life.
Aerobic (oxygen-using) metabolism can be defined as a biological process that typically involves the extraction of energy from any carbohydrate source such as amino acids, fatty acids, etc.
Basically, an aerobic metabolism of amino acid is a process that requires deamination.
Generally, proteins comprises of amino acids and it is responsible for maintaining the proper functioning of the body system.
Transamination can be defined as a biochemical process which typically involves the removal of amino groups from amino acids and transferring them to a ketoacid (amino acid without an amine group), so as to form new amino acids.
Basically, transamination is a reversible oxidation-reduction reaction that is responsible for the deamination of amino acids.
