Answer:

pleiotropy

Explanation:

  • When a single gene influences more than one phenotype that is unrelated to each other then this phenomenon is termed as pleiotropy.
  • The gene that causes pleiotropy is called a pleiotropic gene.
  • In the given question, the disease that is Marfan syndrome is occurring due to the inheritance of a single allele that is defective. However, this single gene is affecting various phenotypes such as the length of the limbs, the cardiovascular system and the eyes and all these different characters affected are quite unrelated to each other.
  • Therefore, it can be said that Marfan Syndrome is an example of a pleiotropic condition.

k0ka [10]

The correct answer is - phototrophs.

Some of the autotrophs are able to convert the electromagnetic energy from the sunlight into chemical energy in the form of reduced carbon (C). The autotrophs that are able to perform this are called phototrophs. The green plants and the algae are the most prominent members of the phototroph autotrophs.

In essence, the autotrophs are producers, meaning that they are able to produce their own food. The phototrophs are the part of the autotrophs that are able to use the sunlight to produce small amounts of ATP as well as the energy carrier NADHP. By producing the ATP and the NADHP the phototrophs manage to produce glucose, or rather sugars, which are actually their food.
