Answer:
They cannot use the reasoning, "Dolphins and Ichthyosaurs form a paraphyletic group."
Explanation:
This is because they always form a monophyletic goup. Both of the species have specific morphological similarities that are enough to consider them in monophyletic group instead of a divergent paraphyletic.
The correct answer that would complete the given statement above is cerebral cortex. The outermost layer of the brain, the cerebral cortex, is housed in the cerebrum. The cerebral cortex consists of folded gray matter. It is responsible for the interpretation of input from different sources. <span>The </span>cerebral cortex<span> lobes include the parietal, frontal, occipital and temporal lobes.</span>
If we sprinkle salt on cucumber slices, it releases water after some time due to the process of osmosis. Osmosis is a process where solute or salt from higher concentration moves towards lower concentration through a semi-permeable membrane. Here, in this case, the salt concentration is more outside on the cucumber slices. The individual cell membrane of cells present in cucumber slices acts as a semi-permeable membrane. Inside the cucumber cells, there is less concentration of salt or solute and more concentration of water. Therefore, the salt from outside goes inside individual cells and the water comes out as it also travels from higher concentration to outside lower concentration through a semi-permeable membrane.
1/2.
the gene Rr separate to R and r.
the gene rr separate to r and r.
then they mix, turn to
Rr, Rr, rr, rr.
because wrinkled gene r is recessive, so only rr would be wrinkled. the probability would be 2/4=1/2.
The correct answer is "Hfr strains have the F plasmid integrated into the chromosome".
This is in the context of horizontal gene transfer in bacteria. This gene transfer consist of transferring an "F plasmid" in a process called bacterial conjugation. Bacteria with the F plasmid are termed as "F+ strains". The key difference between an Hfr strain and a F+ strain is that while they both have the F plasmid; the Hfr strain have the F plasmid integrated to its chromosome while the F+ strain have the F plasmid not integrated to the genetic material and only freely floats in the cytoplasm.
