Answer: the child's phenotype will be normal.
The child will acquire that disease.
Explanation:
The mitochondrial DNA is a small circular chromosome that exists in the mitochondria. The mitochondria is the power house of the cell and all its 37 DNA are essential for a normal function of the mitochondria. the mtdna is passed directly from the mother (through the egg cell) to the child either a male or female but the son cannot pass his mtdna to his child. Thus, if a man with this disease marries a woman not affected, the child's phenotype will be normal. But if the wife has the disease, this willl be passed from her to her child me it a male or female.
Answer:
15,000 from green plants to rabbits
1,500 from rabbits to weasels
150 from weasels to eagles
Explanation:
10% of the energy is being passed on from one level to the next, it goes as 150,000 to 15,000 to 1,500 to 150 to 15 to 1.5 to 0.15 to 0.015 and so on. (hint just move one zero to get the answer much easier)
Albinism is a recessive trait characterized by an absence of pigment melanin responsible for skin and hair color. Actually, albinism is caused by a defect in gene for enzyme which synthesizes melanin. The central dogma of molecular biology explains that the sequence of DNA specifies the sequence of mRNA, which, further, specifies codes for the sequence of proteins. Since a gene is a segment of DNA, altered gene will cause altered mRNA which will cause altered protein. Thus, <span>defect in gene for enzyme which synthesizes melanin will cause the absence of melanin and consequently, albinism.</span>
Answer:
For the object of to be considered alive , it must have DNA and all the characteristics of living things.
Explanation:
If one is to determine whether the object is alive or not the object should possess all the properties of living things. firstly, it should have the genetic material the DNA without which the cell can't be alive or the nucleus in case of PROKARYOTES. it should have the ability to reproduce, move , to grow and to excrete without which it would not be considered alive.
