The ductus arteriosus allows fetal blood to move from the pulmonary trunk into the aorta. The ductus venosus on the other hand is a fetal vessel that transports blood from the umbilical vein to the inferior venacava. Ductus arteriosus is a blood vessel connecting the main pulmonary artery to the proximal descending aorta. It allows most of the blood from the right ventricle to bypass the fetus's fluid-filled non-functioning lungs.
Answer:
Conjugation differ from reproduction because Conjugation transfer DNA horizontally to cells in the same generation.
Explanation:
Conjugation is a process of transfer of genetic material from one organism to another organism to direct contact.
An organism serve as the donor and transfer to another organism which is the receiver.
The donor carry DNA sequence called fertility factor. It transfer DNA horizontally to cells in the same generation. It is a type of genetic recombination that occur between two organisms.
Conjugation normally occur in bacteria.
Answer:
It is called mimicry when a living thing copies the appearance of another living thing as a means of protection.
Explanation:
Mimicry is used primarily by living things as a means for protection and to decrease the chances of the living thing being killed. For example, a frog that is prey to a toad could have bright colors (bright color frogs are often poisonous) that don't mean anything to the frog and it's species, but to the toad, the frog is poisonous and should not be eaten, so the toad does not eat the frog because it is brightly colored.
Without mimicry, the frog would have been eaten because it wouldn't have had looked like a poisonous frog, or something that the toad would avoid.
The appropriate answer is D ! in this the dominant allele is not fully dominant ! this is seen in Snapdragon !
so answer is D
