Answer: I know the first part. It’s through a divergent boundary.
Explanation: the divergent boundary brings the 2 plates away from each other, so it opens up a ridge.
<span>Ayuba Suleiman, also known as Job Ben Solomon was a Muslim of high rank and while on a trip in Gambia, he was captured and enslaved. He endured the long trip on the slave ship Arabella and was ultimately sold to a tobacco farmer. While Ayuba experienced many "normal" experiences of enslavement such as: crossing the Atlantic, being sold into captivity, and escaping, some of his experiences were unusual. Ayuba could speak Arabic and was seen to be educated and well read, and was ultimately set free by the powers that be (even though they had ulterior motives in doing so).</span>
???????? Whats the question
<u>Answer</u>: 2.soil minerals, oxygen, rain, sunlight.
<u>Explanation</u>:
- <em>Abiotic factors </em>are the non-living and physical factors of the environment. For example, rocks, wind, soil etc.
- The<em> biotic factors </em>are the living components of the environment for example plants, animals etc.
- Since <em>soil minerals, oxygen, sunlight, and rain are all non-living components they all fall under the category of abiotic factors. </em>
Answer:
The correct options are:
a) The ability to halt the cell cycle in response to DNA damage.
c) The ability to repair DNA damage.
e) The ability to stimulate cell death processes if the cell is irreparably damaged.
Explanation:
p53 gene has been called 'the guardian of the genome' because its prevents genome mutations which can bear to tumor formation. The main roles of p53 are:
DNA repair (option c): it activates a ribonucleotide reductase which is involved in DNA repair when it is damaged.
Growth arrest (option a): it avoids the cycle cell progression when a damage occur.
Apoptosis (option e): it induces programmed cell death or apoptosis (because every cell must die eventually).
These processes are involved in prevention of tumor formation through activation/inhibition patways which in last instance prevent the replication of cells with a damaged/mutated genome.
