Answer:
The ancestors of mammals diverged from ancient synapsids (reptiles).
Explanation:
The mammals have known to be evolved from a group of reptiles. These group of reptiles were known as synapsids. In fact, some scientists consider mammals as the only living synapsids. The close relativity between reptiles and mammals can hence be seen because they have common ancestors. The synapsids were known to inhabit the earth during the Permian Period.
The scientists, however, do not know from which reptiles exactly did the first mammals grow.
A because like what even is this??
Answer:
II. meiosis
III. fertilization
IV. gametes
Explanation:
Gamete formation and fertilization are the processes performed by all the sexually reproducing organisms. Gametes are the cells that are formed in the male and female sexual organs of these organisms. Formation of gametes occurs by meiosis and therefore, the gametes of a diploid organism are always haploid.
Male and female gametes fuse during the process of fertilization and form the zygote which in turn divide repeatedly to produce an embryo. For instance, sperms and eggs are the male and female gametes that are formed in testes and ovaries of male and female human individuals respectively. The fusion of sperm and egg produces a zygote that finally develops into a young one.
Flounders was the marine fish which was frequently caught commercially in
Explanation:
According to the NOAA Fisheries statistical report in 2012, marine species like flounders, Atlantic croaker, red drum, Black sea bass were the frequent catch in many commercial fishing sites and ports.
Flounders are caught commercially both for human consumption (about 60%) and recreational purposes (about 40%).
Sustainable reharvesting methods help to increase the species population.
These are usually caught using trawls, gillnets, or pound nets.
Rules for commercial catch are instructed to maintain fish net size so as to prevent the catch of juvenile fishes.
