Answer:
The character of sickle cell anaemia does not get fixed in the population Because it has more disadvantages than advantages
Explanation:
Any character will get fixed in the population if the character provides the progeny certain advantage to reproduce better.The rate of malaria infection is low, but such people may have breathing difficulties and organs may fail due to the wrinkled RBC's not able to flow smoothly in the arteries and hence causing blockages. the character may be recessive but again the amount of oxygen carried per healthy RBC is less and that makes breathing difficult . so as a character its a disadvantage for the person who is a career and hence not being selected to be fixed.
<span>Other factors found within its environment can make pioneer species still germinate and thrive. Factors like wind, presence of animals, rain, among others, can help in the germination of the pioneer species even if its immediate environment becomes inhospitable through time.</span>
Answer: probably Nerve cells (for some)
Explanation: Nerve cells are also called neurons. Their function is to communicate with other neurons and the body. The adaptations of a nerve cell are dendrites with receptor proteins, an axon, myelin, synaptic terminals and neurotransmitters.
Answer:
True
Explanation:
Amino acids are coded from the DNA sequence in groups of three bases, that is, three bases (three letter codes) also called codon codes for (or specifies) an Amino acid.
in the above DNA sequence each of the prospective 6 Amino acids will each require a triplet of bases. Thus, the simple calculation of 6×3 yields 18. Thus we need at least 18 bases in our DNA sequence, barring stop codon, to code for Amino acids.
Counting, the above DNA sequence contains 18 bases exactly.
