Answer:
Artificial passive immunity
Explanation:
Artificial passive immunity is the type of passive immunity that is formed in the body of an organism (receiver i.e. a human) to counter or prevent an infection when antibodies that are formed from another organism (donor i.e. the rabbit) is being injected into the organism (receiver i.e. human). These antibodies are developed in the body of a different organism (donor i.e. rabbit) that has been injected with the causative agent that produces antigens that stimulates the production of these antigens to such infection (viral disease). These antibodies are then removed and used in another organism (receiver i.e. human) to provide immunity against such infection (viral disease) in another organism (human).
This artificial passive immunity that is created when the antibodies from the rabbit plasma is injected into a human body usually does not last longer, but provides quick protection and cure to the same viral disease.
Answer:b. Facilitated transport
Explanation:in the usual activities of the cell,it's cell membrane is responsible for the movement of substance in and out of the cell.
Such substances include nutrients,water, oxygen etc.
The plasma membrane select the substances that it allows into the cell thus it is said to be selectively permeable.
The plasma membrane of the cell has a phospholipid bilayer made up of cholesterol, proteins and glycoproteins.
The proteins on the membrane are useful for facilitated diffusion.
In this diffusion process,the proteins helps to carry large molecules across the cell membrane.such molecules includes glucose,amino acids etc.
In the process energy is not expended so it is a type of passive transport.
The Algae is a group of plants, and the seaweed is just one kind of algae. Kelp is actually a subgroup of seaweed and is also the largest form of seaweed. Hope this helps :)♥
The main role of an indicator is to establish the equivalence point when two substance has reached its neutralization process. The purpose of an indicator is to determine how acidic or basic the product or solution is. Indicator solutions work by actually reacting with the components of food that they test for, creating a new substance of a different color. This is a chemical reaction.If the substance that they test for is not present in the food, there will be no reaction, and therefore no color change. The test strips will be more likely to be dark blue or black for Grape, Tomato, Summer squash, Orange Bell pepper as they all contain starch. Color intensity may vary depending on the level of starch found in the samples.
For the
problem presented, the answer that would justify this statement is Apo-repressor
can only bind to the operator site of trp operon when a tryptophan molecule,
which is a co-repressor, binds to it. The correct answer between
all the choices given is the first choice or letter A. I am hoping that this
answer has satisfied your query about this specific question.
