Answer:
C
Explanation:
The globin of the RBC is broken down into constituent amino acids that can be reutilized by the phagocytic cells (this can occur in the spleen, liver and lymph node). The chains cannot be reused in their large form. The heme(iron) is transported by the blood to the bone marrow and is used to make new red blood cells.
Chemical (mutagens)
usually either mimic the structure of nucleotides and are inserted in DNA or either cause
chemical changes (such as alkylation) in nucleotides hence causing mismatching during replication.
Radiation, on the other hand, (due to its high energy) causes double-strand breaks in DNA causing an
increased likelihood of mutations during the repair of the DNA by cell
mechanisms.
Answer:
natural selection is the answer
Answer:
Yes
Explanation:
In the past climate change models were not accurate as they mostly understated the problems which resulted in more damages caused due to inaccurate preparations. However due to new technological innovations, there has been availability and improvement in the tools such as satellites.
This has led to an increase in the accuracy of the climate change models and subsequent planning of costal city infrastructures.
