modifies DNA in order to improve the host or its offspring
Answer: b. chemoautotrophs
Explanation: chemoautotrophs are organisms that obtain energy, molecules, water by the oxidation of electron donors in their environments. Chemoautotrophs are able to synthesize their own organic molecules from inorganic sources. They are different from phototrophs who requires sunlight to make their own food
Answer:
A rainforest with lots of different animals and plants.
Explanation:
bio<u>DIVERSITY</u>
Diversity: a range of different things.
Answer:
convergent evolution
Explanation:
If we have two species that share a similar trait or look alike a lot, but they live in places isolated from each other, and they only have a very distant relation, then it is a case of convergent evolution. This type of evolution occurs with species that are not closely related, but they live in environments where having the same or very similar traits is advantageous. This can often lead to a confusion when looking at the species only on the outside, and it can be very misleading. As an example we can take the sabretoothed predators that existed in the past. Both the smiloden and the thylacosmilus had large saber like teeth, and even their bodies looked very similar, so one would assume that they are closely related, but that was not the case. The smilodon was part of the cat family, while the thylacosmilus was a marsupial, making them very distantly related. They developed same same and some very similar traits because their environment created the evolutionary pressure for those traits to develop as they were advantageous, despite them evolving in totally different places and separately.
Answer:
Option B, Tinea capitis
Explanation:
Superficial fungal infection of skin of head or scalp is known as Tinea capitis.
These fungal infection attack the hair shafts and follicles and is a superficial form of mycosis or dermatophytosis.
Tinea cruris is the superficial infection of genitals, buttocks and inner thighs regions. Hence, option A is incorrect.
Tinea pedis is the superficial infection of foot and regions between the phalanges. Hence, option C is incorrect.
Tinea corporis is the superficial infection of arms, legs or skin. Hence, option D is incorrect.
Thus, option B is correct.
