nalin [4]3 years ago

Answer:

Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.

Can small trees contribute oxygen?
il63 [147K]
Yes, because even though other trees produce more oxygen, the small trees will still produce some oxygen. On top of this there are more small trees than big trees, so even though they make less oxygen, in whole they end up making more when added together!

Assuming dragon genetics follows the same rules as fruit flies, what ratio of genotypes would you expect if the genes were not l
andrew11 [14]

Assuming dragon genetics follow the same rules as fruit flies, we would get the same possible genotype for all 16 offspring provided that the genes are not linked.

Considering dragon genetics, flame eyes (F) are dominant to blue eyes (f) and burbling (B) is dominant to whistling (b).

Now, a dihybrid cross between two homozygous blue-eyed, whistling dragons will yield 16 offspring all with the same possible genotype .i.e. homozygous blue-eyed, whistling type.

Morgan through experiments on fruit flies observed that when the two genes in a dihybrid cross were situated on the same chromosome, the proportion of parental gene combination were much higher than the non-parental type.

He attributed this due to the physical association or linkage of the two genes and coined the term 'linkage' to describe the physical association of genes on a chromosome. The term 'recombination' is to describe the generation of non-parental gene combination.

Answer: The Parathyroid gland

Explanation:

The Parathyroid gland secretes "Parathormone", an hormone that exerts

- direct influence on the bone by INCREASING the release of bone calcium ion (Ca2+) into the blood

- affects the kidney by stimulating the renal tubules to eliminate EXCESS calcium in the urine.

Thus, the calcium balance of the body depends on the secretion of the Parathyroid gland
