The rabbit cell is an animal cell. It has a two layered lipid membrane. The lipid membrane is non-polar in nature and will permit the movement of non-polar substrates across itself. Ions and large charged particles cannot pass across this membrane unless the cell expends its store of energy to facilitate their active transport into the cell. Hence Calcium ions and sodium ions will not diffuse across the rabbit cell membrane, whereas water (uncharged), glucose (polar) and oxygen (uncharged) will diffuse across the lipid membrane.
The answer is A hope this helps
Answer:
(B) semiconservative.
Explanation:
According to the model proposed by Watson and Crick, the DNA molecule consists of two polynucleotide chains arranged on a helix around an imaginary axis, rotating to the right (a double helix). That is, the DNA molecule is in the shape of a spiral staircase, in which the "steps" are made up of nucleotide nitrogen bases and the "handrails" are covalently linked phosphate and sugar - so it is said that DNA is shaped like a helical ribbon. Also according to Watson and Crick DNA replication is semi-conservative, because each strand of DNA will give rise to another strand that will be complementary to its nucleotides.
Answer:
A question is developed from some observations and the hypothesis is a tentative explanation for that
