(b) No. HIV can only be caught by another person of they come in contact with your blood or through sexual intercourse. So it is not possible for others to become infected if they didn't come in contact with the person's blood or have unprotected intercourse. There is no reason for a HIV+ve person to isolate themself from the outside world. They are people just as we are but they only have something that can cause them to be really sick.

Pharyngolaryngectomy involves surgical excision of the hypopharynx and larynx, reported with codes 31390 or 31395, and these codes are differentiated based on with or without ______________.
Answer:
The answer is "Complications"
Explanation:
Pharyngolaryngectomy is an operation to eliminate/remove the larynx (voice box) and the pharynx (the territory at the rear of the mouth and throat). The activity is intense, requiring a general anesthetic and a stay of a little while in medical clinic. Now and then it should be completed in two phases, the subsequent stage being to revamp the structures in your neck however much as could reasonably be expected. This will expect unions to be taken from your chest, back or lower arm.
You should be offered broad pre-operative guiding in anticipation of the deficiency of your voice, in spite of the fact that it is conceivable to recapture a decent measure of vocalization with language instruction. After the activity you should inhale through an opening in your neck which will be a permanent feature.

write any two method for identification of fossils?
Traces of the dead bodies present on the sedimentary rocks are fossils identification parts. By the physical appearance as well we can see the fossils and the types.
What are the ways by which fossils form ?Molds and the casts are the ways by through the fossils are formed out.
Something becomes fossil then it is mineralized or later becomes is made of the minerals. This is usually meaning an increase in the weight. A fossil bone is just heavier than the normal bone that is noticeably so. So if object is heavy then it just might be the fossil. Sediment might fill mould and later form cast fossil.
Have an eye that looks for the detail Look for the regular lines along with the marks or the patterns on the pebbles just like ridges or the growth lines in the shell. Looking for the tiny pieces that are among the beach pebbles and not only the big stones. Often the crinoid stems or the belemnites can also be small as the little fingernail.

Which of the following is not a function of the cell membrane?
Answer:
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. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

6. This system is responsible for filtering out liquid cellular waste that has 10 points
been collected in the bloodstream. It also provides a location to store the
waste until it is ready to be removed from the body. Which body system
is being described?
A-cardiovascular
B-excretory
C-muscular
D-immune
Answer:
the correct answer is B
Explanation:
cardiovascular is your heart pumping blood
muscular is your muscles
immune is how you fight of disease
so that would only leave B-excretory
B and b represent, respectively, the dominant and recessive alleles of a gene pair. Half of the F1 generation expresses the recessive condition, and the other half expresses the dominant condition. What are the most likely genotypes of the P generation
Answer:
Bb and bb
Explanation:
The most likely genotypes of the parental generation would be Bb and bb.
If Bb and bb are crossed, such that:
Bb x bb
offspring: Bb Bb bb bb
Bb = 2/4 = 1/2 = 50%
bb = 2/4 = 1/2 = 50%
hence;
1/2 or 50%% of the offspring would express the dominant condition in the form of Bb and the remaining 1/2 or 50% of the offspring will express the recessive condition in the form of bb.

why saturated solution prepared at higher temperature gives crystal on cooling
Answer:
Cristal is formed when the solution is cooling because the solvent can't keep all the molecules of the substance and these molecules are beginning to leave the solvent and form solid crystals.
Explanation:
It means that every crystal is formed of one molecule of the solvent. When the solvent reaches room temperature, it is moved to the ice bath to finish the process of crystallization.

1. Do you think nuclear power is safe to use? Would
you feel comfortable living next to a nuclear power
plant?
Answer: No, I do not think that nuclear power is safe to use. Any radioactivity in general is dangerous in itself. I would not feel comfortable living near a nuclear power plant, due to the radioactivity, the pollution, and the huge health risks of doing so, such as extremely elevated risk for cancer
Answer:
I don't really think nuclear power is safe to use, it's too unpredictable. I would not want to live anywhere near a nuclear power plant on account of the fact that there have been multiple accidents involving nuclear power plants, for example, Chernobyl in 1986, Fu kushima in 2011, and Three Mile Island in 1979.

How does the structure of DNA determine how genetic information is inherited?
The basic structure of DNA is called a double helix. It contains two strands, and each strand is produced of nucleotides. Specific sequences of nucleotides make up genes, which provide instructions for cells. The amount of A bases in DNA equals the amount of T bases, and the amount of G bases equals the amount of C bases.

The process takes place in the chloroplasts of green plants and oxygen is a by-product of the reaction.
Cellular respiration, on the other hand, involves the breakdown of foods in the form of glucose to release the energy stored in them for the use of cells. The glucose reacts with oxygen to produce energy in the form of ATP while carbon dioxide and water are produced as by-products. The process takes place in the mitochondrion and both producers and consumers require it in order to generate energy for metabolic processes.

What are polymers? Through which process are they synthesized or made?
Answer:
Polymers are large molecules with a chain structure that can be linear, branched, and cross-linked. Polymer chains are mainly composed of covalently bonded atoms.
Explanation:
Polymers can be synthesized using reactants of petrochemical or renewable origin. Polymers can be synthesized in two methods, by step-growth and chain polymerization. Both ways of polymerization are random processes during which chains of different lengths are formed.
The basis of step-growth polymerization is the condensation reaction.
