Active and passive immunity involves all of the following except receiving mother's antibodies through breast-feeding. exposure to a pathogen either naturally or by vaccination. memory B cells responding to a second exposure to the same pathogen. the stimulation of a nonspecific immune defense. receiving mother's antibodies through the placenta.
Explanation:
Immunity is the ability of an animal to resist infection.
There are two types of immunity in the body; INNATE OR INHERITED IMMUNITY AND ACQUIRED IMMUNITY. Inherited immunity it is the type of immunity that one is born with. It is passed from parent to offspring.
Acquired immunity is immunity to particular infections that is not inherited but has developed in the animal's life as it interacts with its environment. Acquired immunity can develop naturally in which case it is called NATURAL ACQUIRED IMMUNITY OR ARTIFICALLY.
ACTIVE IMMUNITY is the form of acquired immunity in which the body produces its OWN antibodies against infections. While PASSIVE IMMUNITY is the form of acquired immunity in which an individual is PROTECTED AGAINST INFECTION BY RECEIVING ANTIBODIES.
NATURAL ACQUIRED IMMUNITY
when attacked by the same pathogens again, they don't became seriously ill. this is because memory cells are able to recognise the antigens and stimulate the immune system to produce antibodies against the pathogens. This is known as NATURAL ACTIVE ACQUIRED IMMUNITY. It develops when one recovers from an infection.
During pregnancy, the mother passes antibodies across the placenta to the foetus. At birth the baby gets antibodies from the mother through breast milk. This is natural passive acquired immunity.

Which of the following is a characteristic of a population that is in Hardy- Weinberg equilibrium? A. The gene pool gets smaller in each generation. B. The alleles mutate in every generation. C. There are equal amounts of immigration and emigration. D. The frequency of each phenotype does not change.
The gene pool gets smaller in each generation, which is the characteristic of a population that is in Hardy- Weinberg equilibrium. The correct option is A.
What is a gene pool?The gene pool encompasses all of a species' genetic diversity. The gene pool's size can change. When organisms have mutations that are passed down to the next generation, the gene pool expands.
When all of the organisms carrying a particular allele die before having offspring, the gene pool shrinks.
Thus, the correct option is A.

Write a short description of the life cycle of a flowering plan
Answer:
Flowering plants begin as seeds. These seeds store energy and food within them long enough to reach the right environment and germinate. Germination is the development of a plant, growing from a seed into a seedling. Seedlings are the second stage of a flowering plant's life. This is when their roots begin to form and photosynthesis can begin. Next comes the growth period. After the seedling is planted, it requires a lot of food and energy as more leaves begin to emerge. The next stage of a flowering plant's life is the flowering stage itself. This is when buds and flowers begin to sprout. It enters the reproductive stage and pollination begins, allowing more seeds to be sown.
Which of the following could result in secondary succession?
the formation of a tall sand dune on a previously grassy beach
a vast glacier in motion forming a U-shaped valley in its wake

B. Cellulose is a type of fat.
C. Cellulose is a complex carbohydrate.
D. Cellulose dissolves easily in water.
Answer:
the answer is d
Explanation:
because as the first statement tell you it is a carbohydrate so B is eliminated .
and we know that it is found in plants so A is eliminated too.
and it makes cell wall and can not easily dissolve in water and d is eliminated so definitely the answer is C
The true statement about cellulose is a complex carbohydrate. The correct option is C.
What is cellulose?Cellulose is a glucose-based linear polymer (polysaccharide) that is found in nature. Its chemical formula is (C6H10O5)X. Plants typically produce it through synthesis.
The primary characteristics of this polysaccharide are biodegradability and hydrolysis resistance. The sturdy formation of plant cell walls is greatly aided by cellulose, a hard, fibrous, and water-insoluble polysaccharide. 20.
The fibrils (bundles of microfibrils) and microfibrils (bundles of polysaccharides) made up of cellulose chains make up the plant cell wall. It is colorless and tasteless.

Explain why the biodegradation of plastic might be more hazardous to the environment than the presence of plastic as marine debris.
Answer:
they generate a large amount of macrobiotic flora which can cause diseases to humans as well as animals
Answer:
While plastic is not generally considered biodegradable, it can be broken down by the action of photodegradation and certain microbes. The breakdown products of plastic, however, are extremely toxic to marine life and once the plastic breaks down they are free to enter into the food chain. Therefore, while plastic marine debris is hazardous and dangerous to marine organisms, the toxic breakdown products of plastics have the potential to do even more damage.

What is Cell membrane?
Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane.
All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment.
A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane. The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions.
