Answer:
According to the internet:
"An eradicated virus that used to be contagious, disfiguring, and often deadly."
The probability of Sean to both sing and dance well is 50%.
<h3><u>Explanation:</u></h3>
The gene that is dominant is expressed in phenotype of the individual and the genes are actually obtained from the parents.
Here two characters are mentioned which are singing and dancing.
The dominant character i.e able to sing is marked by gene S and the corresponding recessive allele is marked by gene s.
Similarly, the ability to dance is marked by gene D and recessive allele is marked by gene d.
So, the mother is heterozygous and she can sing well, but can't dance. So her genotype is Ssdd.
The father can't sing and is homozygous, so his genotype is ssDD.
Gametes from the mother is Sd and sd. While the gamete from the father is sD.
So the probabilities of the progenies are SsDd and ssDd.
So the probability of Sean to both sing and dance well is 50%.
Answer:
C) Mitochondria
Explanation:
Mitochondria generate most of the heat in endotherms. While many insects are ectotherms (animals in which their heat source is primarily from the environment), others are endotherms (animals which can produce heat internally by biochemical processes).
The correct answer is option C, that is, the Operons afford the organism the opportunity to simultaneously monitor the transcription of multiple genes, whose products are active in the same process.
The genes, which correspond to a particular metabolic procedure are usually under the control of a single promoter in a bacteria. This is known as Operon that assists in monitoring the expression of genes taking part in the similar metabolic procedure.
Answer:
C is the correct option. Storage of carbohydrates is not a function of the skeletal system.
Explanation:
Option A is correct because the skeletal system has parts like the red bone marrow in which red blood cells and white blood cells are produced.
Option B is correct because the bones store minerals like calcium and phosphorus.
Option D is correct because the major function of the skeletal system is to provide support and protect the vital organs of the body.
The skeletal system is not involved in storing carbohydrates. Hence, all statements are true except for statement C.
