In human reproduction, this is a very important hormone that works with fsh. in women, it stimulates the production of sex hormones in the ovaries as well as during ovulation. in men, the same hormone stimulates testosterone production in the testes. what is this hormone? a) atp b) gh c) lh d) tsh

The correct answer is LH or Luteinizing hormone.

Like FSH, LH refers to a gonadotrophic hormone, which is discharged and generated by the cells in the anterior pituitary gland. It plays an essential role in monitoring the activity of the testes in men and ovaries in women.

In men, LH instigates the Leydig cells in the testes to generate testosterone that functions locally to encourage production of sperm, and in women, the LH conducts distinct functions in the two halves of the menstrual cycle. The LH instigates the corpus luteum to generate progesterone that is needed to encourage the initial phases of pregnancy, after fertilization.

parasites can detrimentally affect their host, but also must not allow their host to die before they can complete their life cycle. some parasites have complex life cycles with many different hosts, and have had to find ways of persisting in many different environments during the change from one host to another. ectoparasites live outside the body of the host, and can more easily  disperse, but are  more exposed to predators, parasites, parasitoids. endoparasites live inside the body of the host, and are therefore protected from the outside environment. but they can be  attacked by the host's immune system. they have therefore developed  mechanisms for dispersal such as  complex life cycles.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
