Answer: Option A
Explanation:
A tunicate is marine invertebrate animal which is a part of chordates. They have notochords and dorsal nerve chord. The subphylum of the organism is called as Urochordata.
The adult urochordates lack notochord but the larval stage of the urochordates have notochord. This is because it helps in swimming of the organism which is required only at the larval stage.
The adult stage of the tunicates is sessile and they do not swim so they do not require notochord.
Homozygous means "the same" and Heterozygous means "different". If a pheno type is homozygous, for example, it could be XX or xx, while heterozygous could be Xx. Hope that helps.
Chromosomes; chromosomes can mutate during the creation of the next generation with semen and the egg.
Answer:
The process of cellular respiration allows plants to break down glucose into ATP.
Explanation:
Although plants use photosynthesis to produce glucose, they use cellular respiration to release energy from the glucose.
The most plausible hypothesis to explain why species richness is higher in tropical than in temperate regions is that B) tropical regions have more available water and higher levels of solar radiation.
Hope this helped!!
