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.
Answer:
Option A, Competition has restricted the ranges of both species
Explanation:
When two species which depend on the exactly same kind of resources, get into a mode where they prefer to stay in two different ecosystems without interfering each other’s circle and thus they get excluded from each other due to competition. This phenomenon of the ecosystem is called Competitive exclusion
According to Gause's Law of competitive exclusion two species which are competing for similar kind of resources are unable to stay together.
Hence, option A is the correct choice.
Cellular resperation because photosynthesis is used for plants while cellur respiration is used for both plants and animals
