I) Locus- the chromosomal site where a specific gene is located. A locus is a fixed position on a chromosome, like the position of a gene or a marker. Each chromosome carries ,many genes; human's estimated haploid (n) protein coding genes are about 20,000, on the 23 different chromosomes.
ii) Interference; the observed double crossover frequency differs from the expected double crossover frequency. Cross over interference is used to refer to the non-random placement of crossovers with respect to each other during meiosis. It results in widely spaced crossovers along chromosomes. Interference may exert its effect across whole chromosomes. As chromosomes in many eukaryotes are large, interference must be able to act over megabase lengths of DNA.
iii) Linkage- the tendency for genes located in close proximity on the same chromosome to be inherited together. Normally when two genes are close together on the same chromosome, they do not assort independently and are said to be linked. Whereas genes located on different chromosomes assort independently and have a recombination frequency of 50%, linked genes have a recombination frequency that is less than 50%.
iv) Recombination- the process by which a new pattern of alleles on a chromosome is generated. Genetic recombination is the production of offspring with combinations f traits that differ from those found in either parent. During meiosis in eukaryotes, genetic recombination involves the pairing of homologous chromosomes. This may be followed by information transfer between the chromosomes.
Answer: A.) Heterotrophs compete for the same food source.
A food chain is a linear sequence in which food and energy is being transfered when one organism is fed the another organism in an ecosystem. A food web is a interconnection of two or more food chains. Heterotrophs are organisms which are dependent upon other organisms for the food requirement. In the given condition, the lizard and frogs are the heterotrophs which are dependent upon insects for their food requirement.
<em>Hence, heterotrophs compete for the same food source is the correct statement to describe the relationship between the lizard and the frog on the food web. </em>
Antithrombin is a protein molecule that inactivates several enzymes of coagulation system. It is a glycoprotein produced by the liver consisting of 432 amino acids and three disulfide bonds. The antithrombin found in the blood and the cell lining blood vessels function to prevent unwanted formation of clot.
Question:
To code for the operating microscope, what verbiage are you looking for in the medical record?
(a)loupes were donned for magnification
(b)microdissection may be necessary
(c)due to the intricate dissection under magnification
(d)the operating microscope was steriley draped and brought into the surgical feild
<u>Answer</u>:
Option D: The operating microscope being sterilely draped and brought into the surgical field.
<u>Explanation:</u>
The loupe present is for the single vision magnifying glass, that can be frequently seen with the gold smith and with the watchmakers. The operating microscope are the binocular microscope through which small intricate parts can be observed during repairing of the watches etc. It is used in the surgery for observing the blood vessels as well as the nerves. This instrument can never be sterilized so after the use, it should be properly wrapped sterilely and kept inside the operation room.
