Answer:
increased runoff from rivers
Explanation:
Salinity of the ocean is the degree of concentration of salts in the ocean. It is the extent to which ocean water contains dissolved salt materials in it. It describes the saltiness of the ocean.
When runoff from rivers increases into an ocean, the salinity will reduce drastically. More fresh water implies a reduction in salt water content of the ocean. Runoff reduces or we can say dilutes the degree to which ocean water is salty.

hope this helps!
Answer:
Since the sperm and egg each contribute 50% of the nuclear genetic material to the zygote that becomes the embryo, mitochondria and plastids that become chloroplasts are passed primarily from the female parent, due to a characteristic of the female gametophyte is be larger and formed from one surviving megaspore (option c).
Explanation:
The megaspore is the product of the meiosis of a megasporangio, the cula produces four structures of which only one is transformed into a megaspore.
The female gametophyte is formed from the megaspore which, being large and having a greater quantity of cytoplasm, contains the mitochondria and plastids that will originate the chloroplasts in the embryo.

Implications of natural selection in shaping 99.4% nonsynonymous DNA identity between humans and chimpanzees: enlarging genus Homo. we compare approximately 90 kb of coding DNA nucleotide sequence from 97 human genes to their sequenced chimpanzee counterparts and to available sequenced gorilla, orangutan, and Old World monkey counterparts, and, on a more limited basis, to mouse. The nonsynonymous changes (functionally important), like synonymous changes (functionally much less important), show chimpanzees and humans to be most closely related, sharing 99.4% identity at nonsynonymous sites and 98.4% at synonymous sites. On a time scale, the coding DNA divergencies separate the human-chimpanzee clade from the gorilla clade at between 6 and 7 million years ago and place the most recent common ancestor of humans and chimpanzees at between 5 and 6 million years ago. The evolutionary rate of coding DNA in the catarrhine clade (Old World monkey and ape, including human) is much slower than in the lineage to mouse. Among the genes examined, 30 show evidence of positive selection during descent of catarrhines. Nonsynonymous substitutions by themselves, in this subset of positively selected genes, group humans and chimpanzees closest to each other and have chimpanzees diverge about as much from the common human-chimpanzee ancestor as humans do. This functional DNA evidence supports two previously offered taxonomic proposals: family Hominidae should include all extant apes; and genus Homo should include three extant species and two subgenera, Homo (Homo) sapiens (humankind), Homo (Pan) troglodytes (common chimpanzee), and Homo (Pan) paniscus (bonobo chimpanzee).
uhhhhhhhhhhhhhhhhh thanks
