Answer:
Option B, the graph with high levels of RNA-amino acid and a low amount of RNA-DNA.
Explanation:
RNA is understood to be the first genetic material in cells because:
RNA is capable of both storing genetic information and catalyzing chemical reactions.
Essential life processes like metabolism, translation, splicing, etc. evolved around RNA.
It has the tendency of self-replication.
Therefore, RNA-amino acid hydrogen bonds were more readily abundant than RNA-DNA bonds.
The direct product of photosynthesis is actually the three carbon sugar that can be used to make glucose.
Answer:
keratinocytes
Explanation:
The skin contains various types of cells like melanocytes, keratinocytes and Langerhans cells. The Keratinocytes constitute about 90% of the human skin and are mostly present in the basal skin.
The keratinocytes produce keratin protein which protects the skin and some keratinocytes contain keratohyalin granules which are filled with cysteine-rich and histidine-rich proteins. The keratin and these granules make the skin waterproof.
Thus, keratinocytes are the correct answer.
Biogeographic isolation : Isolation through distribution of Species in geographic space and time
so , one of the answer is The isolation of two populations of the same species
By doing this, decrease the chance of any cross breeds between species, which eventually will led to Speciation
Hi there!
It forms fecal waste. Fecal waste is made of whatever’s left after the large intestine absorbs the needed nutrients and minerals.
