The right option is; D) cork cambium—increase in stem thickness
Cork cambium is a tissue that is located in the stem of many vascular plants. The main function of the cork cambium is to produce the cork which is a strong protective material on the plants outer surface and also to produce a layer of cells that contain chlorophyll on its inner surface.
Answer: True
Explanation:
<u>A cell membrane consists of a lipid bilayer made of polar phosphate head and a nonpolar lipid tail.</u> It is semipermeable and regulates the transport of materials through it. For this,<u> it is selectively permeable</u> and since it is made of lipids, hydrophobic and small polar molecules can diffuse easily through it by simple diffusion and down their concentration gradient. However, polar molecules, large molecules (such as glucose) and ions are not able to pass through it because they are repelled.
To accomplish the transport of these molecules that can not diffuse, proteins embebbed in the membrane function as carriers that enable the transport of polar molecules, large molecules and ions by passive (through facilitated diffusion, down its concentration gradient) or active transport (movement against its concentration gradient).
the cell spends less time in A during cell division
The correct answer is - It allowed Darwin to study characteristics of similar species.
HMS Beagle was the ship of Royal Navy. It was used by Charles Darwin to sail around the world during 1931-1932. He traveled around the world from 26 December 1831 to 27 February 1832. During voyage, he came across rich variety of animal and plant species. He found many similar species on different location due geographical isolation.
