Answer:
The correct answer would be b. Their cells are small and lack a nucleus.
Both archaea and bacteria are prokaryotic organisms that is, they both are devoid of a nucleus and other membrane-bound organelles such as mitochondria, chloroplast et cetera.
They also share a similarity in terms of shape and size of the cells. Both of them are unicellular in nature and can not be seen by naked eyes.
They show variations in their genetic and biochemical ways. For example, archae contains three RNA polymerases whereas bacteria contain a single RNA polymerase.
Their cell wall also show variation in composition. For example, a bacterial cell wall contains peptidoglycans, whereas archae cell wall does not.
Thus, we can say that archae and bacteria are similar in a manner that their cells are small and lack a nucleus.
A. True ! Energy can be lost, but not created nor destroyed.
The correct answer is R-r.
Heterozygous is where the alleles of diploid organisms are different.
Alleles are variations where DNA sequence of gene varies from one individual to another. Other genes may have one allele because if there is low variation. There are genes where by one alleles may be common and others are rare.
Sometimes it can be a disease which causes variation and others may be a healthy. One allele is being inherited from male parent in diploid organisms and others from female parent.
Hello,
Your question states:
Which of the following best describes a sex-linked trait?
Your answer would be:
D. A trait determined by a gene located on an individual’s X or Y chromosome.
