Answer:
Prophage
Explanation:
Prophage is a viral genome (e.g. bacterihage genome) which is inserted into host genome (e.g. bacterial genome). Such integrated genome-prophage is in its latent phase, because there is no lysis or disruption of host cell. After the latent period, prophage induction occurs in which viral replication begins.
Answer:
b. Hiccupping is a vestigial reflex that suggests a common ancestry between humans and amphibians.
Explanation:
Hiccupping refers to an involuntary contraction of the diaphragm that usually occurs several times per minute. Some research has suggested that hiccuping is an evolutionary remnant of amphibian respiration. This is because the mechanism is remarkably similar to the way tadpoles gulp air and water across their gills. This would mean that hiccups exist due to an antecedent to modern lung respiration.
Answer:
The final volume is the sum of the initial volume and the volume of the object.
Explanation:
Since we know that the volume of the object is the difference between the final and the initial volume, let the volume of the object be ∆V, let the initial volume be V1 and let the final volume be V2.
From;
∆V= V2 - V1
V2= ∆V + V1
Hence the answer above
Myelin sheath. It is a layer of lipids produced by Schwaan cells around the axon of neurons. The sheath increased the rate of electric impulse transmission through the axon, several folds. This process is called saltatory conduction where impulse ostensibly hops from a node to another.
Explanation:
endoderm, mesoderm, and ectoderm
