As a form of anaerobic respiration, glycolysis occurs in the cytoplasm. The end products (net) are 2 molecules of ATP, 2 molecules of NADH, and 2 molecules of pyruvate.
Answer:
C As sperm mature, they migrate from the seminiferous tubules into the lumen.
Explanation:
Answer C is false. Different types of germline cells migrate through the seminiferous tubes into the lumen, but not the sperm. Primary spermatocytes located near the basal lamina of the seminiferous tube generate secondary spermatocytes (through meiosis 1) that are located closer to the lumen in relation to the primary spermatocytes; in turn, secondary spermatocytes generate spermatides (through meiosis 2) that are even closer to the lumen. Finally, the spermatides are transformed into sperm through spermatogenesis. Sperms are located very close to the lumen to be released into the lumen through spermiogenesis.
Answer:
59
Explanation:
The mass number of an atom is usually the sum of the protons and neutrons in its nucleus. The common isotope of Cobalt has 27 protons and 32 neutrons. However, there are several other isotopes (less stable) of cobalt with a higher mass number such as cobalt-60.
Parthenogenesis- Continues reproduction despite single-gender dominance.
Parthenogenesis is a form of asexual reproduction (reproduction requiring only one parent) that allows a female organism to give birth to young one without the presence of a female.
Broadcast spawning- allows large production of offspring.
Marine animals, especially the bony fish, commonly reproduce by broadcast spawning, which is an external method of reproduction where the female releases many unfertilized eggs into water and at the same time the male releases a lot of sperm into the water which fertilizes some of these eggs.
Pollination - Obtains genetically different varieties of plants.
Pollination involves the transfer of pollen grains from the stamens, the flowers parts that produce pollen grains, to the ovule-bearing organs or to the ovules. There are many advantages of pollination especially the cross pollination most importantly the introduction of genetic diversity to the plant, which keeps them resistant to diseases.
Herding- protects calve from predators
Many types of animals seek the company of others. Several benefits are gained by the act of gathering into groups of the same species which includes safety from predators, access to mates, and help in finding food.
