Which region of the Ig molecule interacts with the antigen? What makes the region suited for this purpose?
Answer and Explanation:
Immunoglobulins (Ig) are proteins that are composed of 4 polypeptidic chains: 2 heavy chains (H) and two light chains (L). They assemble in a structure with a 'Y' form. This structure has two regions: the Fab region and the Fc region.
The region of Ig which interacts with the antigen is the Fab region. That is possible because the Fab region presents variability in the amino acid sequence which determines the specific complementary shape with the antigen structure (like a lock and the key).
Please as help! Explain how important has been for animals to have internal fertilization? Provide two
arguments supporting your answer
Answer:

The site which responds to the hormone?
Answer:
Most hormones circulate in blood, coming into contact with essentially all cells. However, a given hormone usually affects only a limited number of cells, which are called target cells. A target cell responds to a hormone because it bears receptors for the hormone.
Answer:
According to toppr
Receptors are specific proteins located on target tissues to which specific hormones bind to produce their effect.
Binding of a hormone to its receptor leads to the formation of a hormone-receptor complex. Formation of Hormone-Receptor complex leads to certain biochemical changes in the target tissue.
Hence Receptor site responds to a hormone.
So, the correct answer is 'Receptor'.

fetal DNA is examined.
Answer:
Amniocentesis

It involves inserting a long needle to extract fetal cells from the fetus's surrounding fluid for these diagnostic purposes. It is a risky procedure that has since been widely replaced by cell-free DNA testing.
According to the endosymbiotic theory of the origin of eukaryotic cells, how did mitochondria originate?
a) when a protoeukaryote engaged in a symbiotic relationship with a protocell
b) from infoldings of the plasma membrane, coupled with mutations of genes for proteins in energy-transfer reactions
c) from the nuclear envelope folding outward and forming mitochondrial membranes
d) by secondary endosymbiosis
e) from engulfed, originally free-living proteobacteria
Answer:
e) from engulfed, originally free-living proteobacteria
Explanation:
The bacterium was captured by a eukaryotic cell and then the cell evolved into the mitochondria we know today!
According to the endosymbiotic theory of the origin of eukaryotic cells, mitochondria formed from engulfed, originally free-living proteobacteria. The correct option is e.
What is proteobacteria?Proteobacteria are a major phylum (group) of bacteria. Pathogens such as Escherichia coli, Salmonella, Vibrio cholerae, Helicobacter pylori, and many others are among them.
Others are free-living, and they include many of the bacteria that fix nitrogen.
Proteobacteria, which includes mesophilic and neutrophilic bacteria, is the second largest phylum of hydrogenogenic CO oxidizers. Members of this phylum can be found in a variety of classes.
According to the endosymbiotic theory, mitochondria and chloroplasts were once free-living bacteria that were phagocytized but not digested by another cell.
According to the endosymbiotic theory of eukaryotic cell origin, mitochondria evolved from a rickettsia that was phagocytized but not digested by the larger cell.
Thus, the correct option is e.

a car acceleration from a 10 m/s to 60 m/s in 12 seconds. what is the acceleration
Answer:
4.167 m/s^2
Explanation:
vi = initial velocity = 10 m/s
vf = final velocity = 60 m/s
t = time = 12 s
a = acceleration, unknown
Use the following equation to find a:
(vf - vi)/t = a
(60 - 10)/12 = 4.167 m/s^2
4.167 m/s^2 = a
Hope this helps!! :)
