C. The separation of sister chromosomes
As the plate moves from the ridge, sediments from erosion settle on the plate as it nears land.
Answer:
Water is a covalent compound.
Explanation:
covalent compounds are individual molecules characterized by the sharing of electrons between two or more atoms. Two atoms with similar electronegativity will not exchange an electron from their outermost shell; the atoms instead share electrons so that their valence electron shell is filled.
Example:
Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), Water (H2O) and iodine monobromide (IBr).
Properties:
1. At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas.
2. Covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.
3. Covalent compounds have lower melting and boiling points.
Answer:
leaves more viable offspring than others of its species
Explanation:
Greater fitness is being conferred on an individual organism compared to the other individual member of a species population if that individual does not only just competes favorably for the limited resources available than the rest individuals, but is in fact able to reproduce more rapidly and thereby pass on such favorable traits, which makes them better competitors, to as many of their offspring as possible. Over time, you will find most of the offspring they leave behind more common in the population than the other.
If an individual organism is referred to as having a greater fitness compared to another individual of the same species, what it simply means is that the organism <em>leaves more viable offspring than others of its species</em>.
Answer:
Explanation:
The history protein H2A, H2B, H3 and H4 forms an octamer ( 2 each of the four histones) around which the DNA is wrapped. They help in packaging the DNA allowing for compaction of the DNA
Linker histone H1 and a length of DNA (linker DNA) links two nucleosomes together and they also play essential role in chromatin strucrure, stabilizing it and also modulating accessibility of the DNA to biological processes.
