The human cell has the largest surface area to volume ratio is Sperm cell or spermatozoa and its ratio is 1.55
<u>Explanation:</u>
Spermatozoa is a uni-flagellar motile sperm cell that basically determines the sex of an offspring. It moves from the haploid male gamete,its contributes in 1/2 nuclear genetic information to diploid.
The surface area of sperm cell is measured by micro-metric method or electron mircographs using stereo-logical method. While the volume will be measured by stereology or radio label volume exclusion method. The volume and surface area inversely proportional to cell size.
With your sheep brain, identify the major lobes of the brain: frontal, temporal, parietal and occipital.
The correct answer is: damage to the left posterior brain or left optic radiation.
This condition characterized by the loss of half of the visual field on the same side (right side in this case) in both eyes is called homonymous hemianopsia. This happens because information from the optic nerves crosses to the other half of the brain via the optic chiasm (X shape).Since, the visual images from the right side travel from both eyes to the left side of the brain, it is most likely that the injury, tumor or trauma occurred on the left side of the brain. Stroke can also be the cause for the hemianopsia.
Answer:
We breathe because oxygen is needed to burn the fuel [sugars and fatty acids] in our cells to produce energy.) What happens in the process of respiration? (Oxygen is brought into the lungs via breathing, where it is transported by red blood cells to the entire body to be used to produce energy.
Explanation:
I think The Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds
