Answer:
Increasing the size of the cube-shaped cell increases the volume. However, the surface area-to-volume ratio decreases. This means that the simple diffusion would take more time distribute nutrients across the cell (and even in the eliminate waste). It would need bulk transport such as vesicle transport, otherwise cell activities would slow down.
Answer:
Stomata are the organs present on the stem and leaves of the plant and help in the gaseous exchange and evaporating water present in the aerial parts of the plant. Mainly leaves stomata plays role in gaseous exchange and transpiration which is the evaporation of the aerial water of plants by opening and closing the stomata. Stomata are small pores mostly and normally present under the leaves and regulated by the guard cells, dum bell shaped cells to close or close it.
Other than closing and opening the stomata, stomata density also can affect the rate of gas exchange as well as transpiration. Stomata density is the presence of the numbers of the stomata per unit area. In heat or sunny area the stomata density is higher than the shady or dark area to increase the transpiration in order to cool down the leaves of the plant which prevent the chloroplast proteins to denature.
Answer:
<h2>The answer is option D- Selective breeding.</h2>
A linear shaped piece of DNA strand is obtained when a plasmid is cut HindIII, Apa1, and Sma1.
Explanation:
Restriction enzymes are endonucleases which enzymatic proteins which can cut a DNA at specific sequences at particular recognition sites. The sequences recognized by these enzymes are usually palindromic that occurs for a definite length (6 bp, 4 bp, or 8 bp).
They can either be blunt cutters or sticky end cutters. APA1, SMA1, and HindIII are all restriction enzymes which can cut a circular plasmid at specific locations.
These restriction enzymes bind with the DNA at specific locations and cuts them to give linear strands of DNA either with a blunt or a sticky end.
The shifting of the plates upset the environment in a negative way and changed the amount of carbon dioxide going into the air.
