Answer:
half of the offspring's genes come from one parent while the other half comes from the other parent.
Explanation:
An amine and carboxylic acid
The main description of lithogenous came from rocks - Produced
as surface rock is broken down by weathering like wind, rain, freezing/thawing.
It is transported to the oceans by water, wind and gravity much sediment
remains on continental margins. However, some sediment ends up on deep ocean
floor as fine rock powder called red clay, brown clay, or brown mud. While Biogenous
came from remains of living organisms shell and coral fragments. Hard skeletal parts of single-cell organisms
of either calcareous (soluble shell) material or siliceous (non-soluble, clear,
hard) material.
Early cleavage divisions in most embryos are also rapid. One reason for this is that cleaving cells have a modified cell cycle, in which the two gap phases, G1 and G2 are completely omitted, and the cells cycle rapidly between M and S phases. In addition, because the major cytoskeletal systems of the cells are largely devoted to mitosis (microtubules) and cytokinesis (microfilaments) during rapid cleavage division, there is typically an antagonism between periods of rapid cell division and cell movement. Thus as the embryo approaches gastrulation, there is a tremendous slowing in the rate of division (note the slope of the curve at the right).
