Answer: E. all of the above.
Explanation: for human infants to grow and develop normally, the need for them to interact with people (family, friends and the public) cannot be over emphasized. Interaction with people goes a long way in the brain, physical and social development of infants.
Frequent interaction with people helps infants in their communication skills.
Answer:
Validity refers to the degree to which a method assesses what it claims or intends to assess.
Explanation:
Answer:
water and land
Explanation:
I assume this is an open-ended question, so you could make an argument for lots of things, but these are the two most important ones in my opinion. The amount of freshwater on Earth is pretty small, only about 2.5%, and most of that is locked in ice. As the demand for food grows, the demand for water for crops and livestock also grows. This is in addition to the increase in water that is needed for a growing population. Climate change increases this problem because of drought. The second most important resource that will be affected is land. If we need more food, we also need space to grow crops and raise livestock. The available space is also reduced because people need places to live and we need to be able to grow trees for wood to build houses and other buildings. I argue that land and water will be the most in-demand commodities as the population continues to increase.
The switch from mitosis to meiosis in spermatogenesis is regulated by Follicle-stimulating hormone (FSH) levels of Luteinizing hormone (LH) and this is induced by Glial cell line-derived neurotrophic factor (GDNF).
<h3>How does FSH, LH and GDNF help in spermatogenesis?</h3>
- The development and maintenance of spermatogenesis is dependent on the pituitary gonadotropins; FSH and LH.
- FSH works on Sertoli cells and LH on Leydig cells through their receptors FSHR and LHR respectively.
- Self-renewal and differentiation of the spermatogonial stem cells (SSCs) is regulated by soluble factors produced by the somatic Sertoli cells. One of these is glial cell line–derived neurotrophic factor (GDNF).
