Answer:
the enzyme helps to break down food, the enzyme is in the
saliva. It can break down a big food molecules and divide it into a
simpler food molecules so that it can be digested. . Enzymes are
complex proteins that speed up the rate of chemical reactions.
Your answer is B.) Heterozygous, since the prefix 'hetero' usually means separate or different. Hope this helps.
Answer:
The green and red labels are distributed in intermingled patched
Explanation:
Chimera will be produced in which some cell which have taken green will appear green and some that have taken red also appears red in patches.
Answer:
a. The purple allele is lethal in the homozygous state
Explanation:
You cross a purple parrot with a true breeding (homozygous) white parrot and you get 1/2 purple parrots and 1/2 white parrots. This result can only happen if the purple parrot is heterozygous and the white parrot is homozygous recessive (if any of the parents had been homozygous dominant, 100% of the offspring would have had the dominant phenotype).
Then: Pp (purple) X pp (white) ---> 1/2 Pp, 1/2 pp
When you cross two purple parrots you get 1/3 white parrots and 2/3 purple parrots. The 2:1 phenotypic ratio is typical of a lethal allele in the homozygous state.
In a cross of two purple parrots: Pp
X Pp, one would expect the genotypic ratios 1 PP : 2 Pp : 1pp and the phenotypic ratios 3 Purple : 1 white.
But the PP genotype is lethal, so those individuals die and the only purple parrots we see are the heterozygous ones.
The elephant cell will have 20 chromosomes.
Cells undergo interphase before getting to the mitotic phase. At the S phase of the interphase, the amount of DNA in the cell is double by replication. However, the number of chromosomes remains intact.
Thus, the cell gets to the mitotic phase with the same number of chromosomes that is usually present in normal vegetative cells of the animal.
