Answer:
Endocrine and Cardiovascular system
Explanation:
Excess fat intake leads to different health hazards. They affect the body and cause lipids to clog the arteries thereby preventing blood from quickly delivering oxygen to the body parts.
Excess fat intake causes fatty pancreas and decreases its function.
It also causes series of cardiovascular diseases such as heart attack; elevated cholesterol/atherosclerosis,abnormal heart rhythms, hypertension, stroke etc
Diffusion; the movement of gases through a membrane to a period of higher to lower concentration
Answer:
The correct answer is recessive.
Explanation:
The alternate forms of similar genes are known as alleles. A version of a gene, which to get expressed in the phenotype need to be homozygous at the time of inheritance is termed as a recessive allele. This shows that for a specific trait, a recessive allele only demonstrates its expression when a similar copy of the same allele is present.
There are two forms of alleles known, these are dominant alleles and recessive alleles. The prime difference between the two is that the expression of a dominant allele is always witnessed, that is, whether it is in the heterozygous state or homozygous state. On the other hand, the expression of a recessive allele is only witnessed when it is in a homozygous state.
Answer:
<em>The above statement is false.</em>
Explanation:
<em>When a single nucleotide is changed at a particular position of the nucleotide sequence, then this change will result in the formation of a faulty protein. </em>
<em>This is because that particular position of the genetic sequence is associated with the formation of a particular protein. All the other proteins formed will be normal. </em>
<em>Hence, we cannot attribute all existing changes between the cichlid and coelacanth/frog on this single nucleotide change.</em>
However, if instead of replacement of a T with a C, an addition or deletion had been made, then the entire genetic code would have been altered. This would have resulted in more number of faulty proteins being formed.
