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.
One of the most general forms of discomfort or pain one feels at the time of strenous work out is a burning sensation in the muscles or lungs, which goes away after some time, that is, after stopping the activity. This is a result of an accumulation of lactic acid.
Lactic acid is a by-product of the procedure the body goes through when it requires to generate energy more briskly that it does usually, like when one exercises.
The muscles functioning generally produce energy aerobically, that is, by using oxygen, however, when one push himself or herself at the time of workout and enough oxygen is not accessible, then these muscles start producing energy anaerobically, resulting in production of lactic acid as a by-product and ultimately causing burning sensation.
Cellular reproduction in a plant is asexual, the cell makes a copy of itself. I think the process is called Mitosis.
As temperature increases, the rate of transpiration rises as there is more evaporation.
As precipitation in the atmosphere rises, the rate of transpiration falls. Since precipitation means there is more water in the atmosphere as compared to inside the plant, less water is lost through osmosis.
Answer:
Option (e).
Explanation:
Karl Woese was an biophysicist and microbiologist. He was known as the originator of rRNA sequences in 1967.
Karl determines the 16rRNA sequence by the technique pioneered by Woese. He breaks the prokaryotes into two groups and discovered the third domain of life.
Thus, the correct answer is option (e).
