Answer:
1) abiotic synthesis of small organic molecules (monomers)
2) joining of monomers into polymers
3) packaging of these molecules into protobionts, droplets with membranes that maintained a distinct internal chemistry
4) origin of self-replicating molecules that eventually made inheritance possible
Explanation:
Answer:
True
Explanation:
Oogenesis includes the formation of one egg cell from a single oocyte or egg mother cell. The diploid primary oocytes in the ovaries enter into the first meiotic division and form a haploid secondary oocyte and a haploid first polar body. After fertilization, the secondary oocytes complete the meiosis-II and forms one large ovum and a second polar body. The ovum formed by meiosis-II is much larger than the second polar body due to the unequal distribution of cytoplasm during meiosis-II. This imparts enough amount of cytoplasm in the zygote to support the mitosis without any cell growth.
Answers with Explanation:
A stream’s velocity is LOWER at the bottom and edges. A stream’s invisible DISSOLVED load represents (on average) about 15% of the mass of material transported. A stream with many rapids and waterfalls is likely a YOUNG (AT THE YOUTHFUL STAGE) stream. In a meander, water flowing around the outside of a curve flows FASTER than water flowing around the inside of the curve. An oxbow lake can form near a MEANDERED stream. A DELTA is likely to form where a stream deposits sediment as it enters another body of water.
Answer:
I think they will make the rest die because when one dies then the rest will too.
Explanation:
each coral reef depends on each other to survive
The best thing to do is this:
the subjects in the experimental group should be given large, daily dose of vitamin C while the control group subjects should be given a daily dose of sugar pills that are disguised as vitamin C.
The research can then observe the differences between the two groups.
