Answer:
The correct answer is- 4:0
Explanation:
Marfan syndrome is a genetic problem which affects the connective tissue in the body. The trait for this disease is autosomal dominant which means even one abnormal copy of this gene in the offspring or individual is sufficient to cause this syndrome.
Let S is the allele that is dominant for this syndrome and s is recessive. So if a cross between homozygous dominant(SS) and heterozygous individual (Ss) occurs than all the offspring would have this syndrome.
S s
S SS Ss
S SS Ss
Therefore all 4 offspring would have at least one dominant allele which is sufficient to cause this syndrome. So the phenotype ratio would be 4:0.
Answer:
The correct answer is They both contain carbon ,but only nucleic acid contain phosphorous
Explanation:
Carbohydrates are also called polyhydroxyaldehydes or polyhydroxyketones.Carbohydrates contain carbon,hydrogen and oxygen.For example glucose(C6H12O6).
On the other hand nucleic are composed of nucleotides that contain nitrogen base,ribose sugar and phosphate group.
The presence of phosphate group in the nucleic acid make it different from carbohydrate.
Both a and b is an example of population increase of favored organisms.
The matching DNA strand would be A - T, G - C, A -T, A - T, C - G, or in other words TCTTG (because you had the strand AGTAAC).
Always remember that A pairs with T, G pairs with C, T obviously pairs with A, and C obviously with G.
When conducting a population sampling study, on the first capture attempt, we tag, count, and release the captured individuals. Thus, option "D" is correct.
<h3>What is the mark-recapture method?</h3>
This is a method commonly used in ecology to estimate the animals in the population. A portion of the population is captured, marked and released. Another part of the population will, later on, be captured. This can be used to estimate the population in an assumption that the portion that was captured is proportional to the entire population. This is obtained by dividing the number of marked individuals by the individual marked on the second capture. This is one of the simplest and most practical methods of estimating the population.
Thus, option "D" is correct.
