the function of the marrow of long bones in the body is to?
A.store iron
B. Reduce Friction
C. make blood plasma
D.make red blood cells
Answer:
Make red blood cells
Explanation:
Bone marrow is a spongy substance found in the center of the bones. It manufactures bone marrow stem cells and other substances, which in turn produce blood cells. Each type of blood cell made by the bone marrow has an important job. Red blood cells carry oxygen to tissues in the body.
You learned in the previous lesson that T cells require two independent signals to become activated. When T cells are activated, they acquire effector functions and begin to proliferate. This two-signal mechanism prevents the expansion of self-reactive effector T cells. Similarly, B cell receptor signaling alone is not sufficient to activate B cells. B cells require assistance from helper T cells to become activated by monovalent protein antigens and gain certain immune functions. What changes do you suspect will occur to B cells when they are activated by protein antigen and receive T cell help? (select all that apply)
a) They will generate memory cells that can respond to a subsequent exposure to antigen.
b) Their immunoglobulin genes will be mutated in a way that alters antigen affinity.
c) The isotype of their immunoglobulin (Ig) genes will change.
d) They will proliferate and expand.
e) They will secrete antibodies.
Answer:
a. They will generate memory cells that can respond to subsequent exposure to antigen.
d. They will proliferate and expand
e. They will secrete anti bodies
Explanation:
B cells are type of white blood cells who belong to lymphocyte subtype. They are activated by binding of antigen to receptors on cells surface, against which they initiate and antibody response. Some of these cell proliferate and divide while other become long lived memory cells that respond subsequent exposure to antigen at later stage.

a. True
b. False
2. Dental radiographs allow the practitioner to see many conditions that are not apparent clinically.
a. True
b. False
Answer:
1. True.
2. True.
Explanation:
Diagnostic testing can be defined as a scientific process that typically involves identifying a condition or its cause through a series of procedures and examination.
In Medicine, a diagnostic test can be used to identify a disease (sickness) or cause of symptoms.
This ultimately implies that, a diagnostic test avails medical professionals or experts the opportunity to identify illnesses and underlying causes of symptoms.
1. True: an oral examination limits the ability of a medical professional or expert (practitioner) to have knowledge of what is seen clinically.
2. True: dental radiographs is an equipment which allow a medical professional or expert (practitioner) to see many conditions that are not apparent clinically.
2. Why do scientists often use thermoacidophile group of archaebacteria for research?
Archaebacteria have some unique characteristics.
Although members of kingdom Archaebacteria share many characteristics with members of kingdom Eubacteria, some of their characteristics are unique.
One such characteristic is the ability of archaea to live in extreme conditions.
What is Thermoacidophile archaebacteria?Thermoacidophile archaebacteria are a type of archaea that thrive in extremely hot and strong acidic (with low PH) environments. Thermoacidophile archaebacteria can be found in harsh environments such as in geothermal area, in the deep ocean vents and hot springs. Most of the
Thermoacidophile archaebacteria are chemotrophs (converts chemicals to food). They use sulfur as their energy source. They absorb the sulfur gas that is being released in their environment and reduce it to hydrogen sulphide, fixing it into an energy source.
Thus, this could be the answer.

Apply logarithm to evaluate T given 644 204=400 000 (1+10%)^T,by first simplify the equation.
The value of T after applying logarithm to evaluate the function is 4.9988
Given the expression
[tex]644 204=400 000 (1+10 \%)^T[/tex]
Since 10% = 0.1, the expression becomes;
[tex]644 204=400 000 (1+0.1)^T\\644 204=400 000 (1.1)^T\\\frac{644204}{400000} =1.1^T\\1.61051=1.1^T[/tex]
Take the logarithm of both sides

what are three characteristics of life that archaea bacteria have?
Answer:
The common characteristics of Archaebacteria known to date are these:
(1) the presence of characteristic tRNAs and ribosomal RNAs.
(2) the absence of peptidoglycan cell walls, with in many cases, replacement by a largely proteinaceous coat.
(3) the occurrence of ether linked lipids built from phytanyl chains.

What role does mutation play in the evolution of a species and the development of new characteristics?
Answer:
Mutation plays a vital part in evolution; it is the greatest source of genetic variation. In evolution, it creates a new DNA sequence for a particular gene, creating a new allele. Additionally, recombination can produce a DNA sequence (a new allele) for a specific gene through intragenic recombination.

explain why in the morning plant leaves are moisten
It occurs when there is active absorption of water by roots and transpiration is low i.e. moist and humid conditions. Therefore, guttation generally occurs in the early morning because transpiration is less at that time but water is actively absorbed by the roots.
plz give a correct answer for the question how do canine and molar differ
Answer:
Canines are the sharp, pointed teeth that sit next to the incisors and look like fangs. Dentists also call them cuspids or eyeteeth. Canines are the longest of all the teeth, and people use them to tear food
Molars are the flat teeth at the rear of the mouth. Each molar typically has four or five cusps. They are used exclusively for crushing and grinding. Wisdom teeth are also called third molars. They erupt from the age of 18 onwards but are often surgically removed.Their function is similar to that of the premolars, to grind, tear, and crush food. Molars have a large flat biting surface which makes them perfect for this job.

Two organisms, AABBCCDDEE and aabbccddee, are mated to produce an F1 that is self-fertilized. If all of these genes are on the same chromosome, and there is no recombination, how many different genotypes will occur in the F2
Answer:
2 genotypes: AABBCCDDEE; aabbccddee
Explanation:
The law of segregation (also called Mendel's First Law) describes how genes on different chromosomes segregate into gametes independently of each other. Moreover, recombination (also known as crossing over) is the interchange of genetic material between non-sister chromatids during meiosis. In this case, the five genes are on the same chromosome (i.e., they are linked together and do not segregate) and there is no recombination, thereby they are inherited as a haplotype block to the next generation:
- Genotypes parental (P) lines: AABBCCDDEE; aabbccddee
- Cross P1: ABCDE X abcde
- Genotype F1: AaBbCcDdEe (100%)
- Gametes F1: ABCDE; abcde
- Genotypes F2: AABBCCDDEE; aabbccddee (ratio 1:1)

The complete oxidation of one glucose molecule yields 30 or more ATP . Glucose catabolism includes glycolysis, pyruvate oxidation, and the citric acid cycle. The total yield of ATP includes ATP , GTP , and reduced cofactors that yield ATP from the electron transport chain and oxidative phosphorylation. Which processes yield the most ATP
Answer:
Electron transport chain.
Explanation:
Electron transport chain is the process which yield the most number of ATP as compared to all three major phases of cellular respiration. Glycolysis produces only 2 ATP from the breakdown of molecule of glucose. In the Krebs cycle, one GTP which is an ATP equivalent is produced from the breakdown of one glucose molecule while on the other hand, 32 ATP molecules are produced from the breakdown of one glucose molecule.
