what type of cell signaling is clonal selection?
The clonal selection theory proposes that antigen selects lymphocytes for activation from a population of cells precommitted to produce specific antibody. Implicit in this theory is that antibody-forming cells are monospecific and express cell-surface receptors capable of binding foreign antigens.
Interaction of antigen with these side chains induced the cell to synthesize additional antibody molecules. This proposal seemed untenable once Karl Landsteiner demonstrated that the immune system could produce antibodies to a vast array of antigens; for over 50 years theories of antibody formation postulated that antigen instructed cells to synthesize antibodies complementary to the antigen. The introduction of the clonal selection theory of antibody formation by Macfarlane Burnet in the 1950s revived the idea that antibody-forming cells express cell-surface receptors by which they bind antigen. In 1961, Göran Möller provided the first evidence that antibody-forming cells had antibody (immunoglobulin) on their surface. The antigenbinding specificity of these immunoglobulin molecules was shown to be identical to the antibody that cells will produce when activated. Initially, many immunologists thought that the T lymphocyte receptor would also be an immunoglobulin molecule. However, studies by several laboratories in the early 1980s using a combination of monoclonal antibodies and molecular genetic techniques showed that the receptor consists of two polypeptide chains. The antigen-specific receptors on both T and B lymphocytes are associated with other trans-membrane molecules involved in the transduction of activation signals into the cell.

Answer:
the clonal selection theory proposes that antigen selects lymphocytes for activation from a population of cells precommitted to produce specific antibody. Implicit in this theory is that antibody-forming cells are monospecific and express cell-surface receptors capable of binding foreign antigens.
For example, memory B cells that differentiate after an adaptive immune response are thought to undergo clonal selection so that antibodies produced by newer memory B cells have considerably higher binding affinities to their antigens. And it is a receptor

Kendle wants to play several games of laser tag. She has $35, 5 to play g games. Each game of laser tag costs $5
Answer:
35 ÷ 5 = g
Explanation:
First, you snatch her/his money to do math, then you take the $35 and look the the thing that tells you how much games cost then do 35 ÷ 5 but since you cant solve it just put 35 ÷ 5 = g , and last but not least you take Kendle's money because no lazer tag during a pandemic and run home before you get yelled at because you were at a lazer tag place and took someones money.

Psychological tools are used to understand human behavior and psychological processes
case studies ,surveys ,naturalistic observation , and laboratory observation are examples of descriptive or correlational researches methods . using these methods researchers can describe different events ,experiences,or behaviours and look for links between them
Psychologists study mental processes and human behavior by observing, interpreting, and recording how people and other animals relate to one another and the environment. ... Research methods vary with the topic which they study, but by and large, the chief techniques used are observation, assessment, and experimentation.

When you use a match to light a candle, multiple _______ of energy occur
Answer:
transformations (missing word)
Explanation:
When you use a match to light a candle, multiple transformations of energy occur.
To light a match, mechanical energy must first be converted to thermal energy. The particles in the match release chemical energy that has been accumulated as a result of the thermal energy, which then transforms into further thermal energy and the electromagnetic energy that you see as light.
Multiple energy transformations involving mechanical, thermal, chemical, and light energy occur when you light a match.
Therefore, when you use a match to light a candle, multiple transformations of energy occur.

Hereditary spherocytosis (HS) is a disorder of red blood cells that causes the cells to be smaller and spherical instead of having the usual flattened, biconcave shape. The average diameter of normal red blood cells is 7.2μm, and the average diameter of red blood cells in a person with HS was found to be 6.7μm. The normal red blood cell has an average surface area of 136μm2 and an average volume of 91μm3.
Which of the following provides an accurate calculation of the surface area to volume ratio of an HS red blood cell, as well as a prediction of its effect on the efficient transferring of oxygen compared to a normal red blood cell?
The statement that provides an accurate calculation of the surface area to volume ratio of an HS red blood cell is The ratio is 0.89, and the cells are less efficient at transferring oxygen.
The ratio 0.89 is less than the ratio that is seen in a normal red blood cell, therefore, the cell would be less organized at moving oxygen.Hereditary spherocytosis (HS) is often referred to as a disease that can be inherited. It is known to affects the red blood cells.
Its symptoms includes the killing of red blood cells in the spleen and their removal from the blood stream amidst others.

A special promotion for its 20-ounce bottle of soda, a soft drink company printed a
message on the inside of each cap. Some of the caps said, "Please try again," while
others said, "You're a winner!" The company advertised the promotion with the
slogan "] in 6 wins a prize.
Suppose the company is telling the truth and that every 20-ounce bottle of soda it
fills has a 1-in-6 chance of being a winner. Seven friends each buy one 20-ounce
bottle of the soda at a local convenience store. Let X = the number who win a prize.
Using the principle of binomial probability, the probability that more than 3 friends win a prize is
Recall :
P(x = x) = nCx * p^x * q^(n-x)Given the Parameters :
Probability of success, p = 1/6 q = 1 - p = 5/6 Number of trials, n = 7x≥3Hence,
P(x ≥ 3) = p(x = 3) + p(x = 4) + p(x = 5) + p(x = 6) + p(x = 7)
P(x ≥ 3) = 0.0781 + 0.0156 + 0.0019 + 0.0001 + 0.000003
P(x ≥ 3) = 0.095703
