xxTIMURxx [149]

Answer:

e.)  If exposure to cowpox gives immunity to smallpox in milkmaids, then milkmaids have a natural immunity and their blood should be used to develop a smallpox vaccine.

Explanation:

  • Milkmaids who suffered from cowpox did not suffer from smallpox i.e. they were immune to the disease.
  • If milkmaids did not suffer from smallpox then there must be some element of immunity that they received once they had recovered from cowpox, this would likely be found in their blood as antibodies.

Colt1911 [192]

Answer:

Membrane bound cell organelles

Explanation:

A prokaryotic cell lacks a membrane defined nucleus and all the membrane-bound organelles. A eukaryotic cell has a membrane-bound nucleus and other membrane-bound organelles such as mitochondria, chloroplasts, endoplasmic reticulum, lysosomes, Golgi apparatus, etc.

To determine if a cell is a prokaryotic or eukaryotic, one can look for the nucleus and the membrane-bound organelles. If the cell has a nucleus and membrane-bound organelles, it is a eukaryotic cell. The absence of these structures makes it a prokaryotic cell.

Match each definition to the appropriate term. locus
liraira [26]
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.
