Answer:
Asexual and Sexual reproduction.
Explanation:
Reproduction can either have one or two parents. Based on this there is two types of reproduction:
Asexual: A type of reproduction where a single parent is divided by itself and reproduce its offspring.
Sexual: A process where two parents participate in producing their offspring.
Answer: Flowers need sunlight
Explanation:
Flowers are attracted to the light because its wants makes them grow its kinda like humans eating food well as a flower they need water air and sunlight as there food.
Answer: B (GTP serves as the energy input for AMP synthesis from IMP)
Explanation:
In the de novo synthesis of purine nucleotide, IMP represents a branch point for purine biosynthesis. IMP can be converted to either AMP or GMP.
The formation of AMP from IMP requires GTP; similarly formation of GMP requires ATP. The conversion of IMP to either AMP or GMP is highly regulated – AMP and GMP inhibits their own formation by feedback inhibition of adenlyosuccinate synthetase and IMP dehydrogenase.
passive: doesn't require energy, from high to low concentration
active:requires energy, from low to high concentration
i dont know maybe
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.
