The correct answer for this question would be the third option. The statement that is not true of grasses is that, they include grains. Not all grasses have grains. But they can be resistant to extreme temperature and are widely distributed and they are similar to succulents. Hope this answer helps
Overproduction is a natural phenomenon in which the number of produced offspring is higher than the number of individuals the ecosystem can sustain. Thus, competition for limited resources occurs.
Because of the genetic variation, the organisms within a population have different chances to reproduce. Most often, some organisms have a lower reproductive success than others do.
The number of individuals with a high reproductive success is rather low as few males are very successful at passing on their genetic material.
The number of organisms with no reproductive success is also very low, as these "ill adapted" individuals will disappear from the population extremely quickly.
Genetic variation is the amount of differences between individuals. Thus, no organism taken by itself has any genetic variation.
Plasmodium is a monocellular parasite causing malaria to humans. The parasite's life cycle always includes two hosts, an insect host and a vertebrate host. The parasite's cells are injected into the vertebrate's (human in our case) bloodstream by the insect host (mosquito). There are several stages in its life cycle but the sexual reproduction occurs only in the insect. In the insect, gametocytes (haploid gametes) merge and form a zygote which in turn becomes an oocyst. Oocysts divide multiple times and that way a great number of sporozoites is produced. These sporozoites travel to the salivary gland of the mosquito and are injected into the bloodstream of the second host, the human. In humans, sporozoites infect liver cells and red blood cells.
According to this information, the four statements about Plasmodium which are true are:
-Plasmodium cells are transferred to human cells through mosquito saliva.
-The complete life cycle of Plasmodium requires two hosts.
-Plasmodium cells infect two specific types of cells in humans.
- Inside an infected mosquito haploid gametes fuse, forming a haploid zygote that develops into an oocyst.
