Answer:
write the procedure in the passive voice (reporting fashion )
Answer:
Explanation:
When osteocytes were experimentally destroyed, the bones showed a significant increase in bone resorption, decreased bone formation, trabecular bone loss, and loss of response to unloading. ... The osteocyte is an important regulator of bone mass and a key endocrine regulator of phosphate metabolism.
Answer:
B. Clay can be made into anything (like a cup or a figurine) just like a stem cell can become different types of cells
Explanation:
Answer:
The nucleosome is extremely stable.
Explanation:
The nucleosome when formed is extremely stable the histones are positively charged and the DNA wrapped around them are negatively charged, they have to be stable so as to be able to control the processes of replication, repair, transcriptional activities etc
Some processes including epigenetic mechanisms exist to destabilize the nucleosome. This is to help transcriptional machines fain access to the DNA for mRNA production. The nucleosome is so stabilized that it ensures transcriptional activities takes place at the only the right time and can also return back to its norrmal state when not needed.
Some processor that destabilize nucleosome includes
Acetylation: acetylation of some lysine residue on histone bring about destabilization: unwinding of the history from the DNA.
Histone chaperones: this too aids in the destabilization of the nucleosomes.
Topoisomerases activity: this helps in the unwinding of the DNA to allow transcriptional machineries to have access. ETC.
b) a new highway is built, separating members of a species.
<h3>What is speciation?</h3>
Speciation is the process by which new plant or animal species are developed. When a group within a species separates from other members of its species and evolves its own special traits, this is known as speciation.
<h3>What are the causes of speciation?</h3>
In eukaryotic species, the processes of genetic separation (the division of one gene pool into two or more distinct gene pools) and phenotypic differentiation (the diversification of a population's range of observable physical traits) are both crucial to speciation. There are various theories on how speciation begins, and they diverge mostly in how geographic isolation and the origin of reproductive isolation are accounted for.
<h3>What are the types of speciation?</h3>
Allopatric speciation
Populations that are totally divided (allopatry) by a natural barrier, such as a mountain range, river, or desert, most frequently experience geographic isolation. The two distinct populations have evolved to fit their distinct surroundings, and as a result, they have genetically diverged to the point where they cannot interbreed.
Sympatric speciation
In sympatric speciation, geographic isolation is not present; reproductive isolation takes place within a single population. Reproductive isolation typically occurs when populations are physically separated.
