Answer:

The sun is 400x wider than the moon, but the moon is also 400x closer to the Earth

Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs)
ch4aika [34]

<u>Answer:</u>

Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs). ROSs can damage mitochondria. Damaged mitochondria generate more ROSs than healthy mitochondria. This is an example of a positive feedback mechanism

The reactive oxygen species that are given out by the mitochondria during cellular respiration are the major cause of aging. Though this has a lot of negative effects but this also has a small amount of positive effects such as the start of angiogenesis or cell proliferation.

Which of the following is NOT TRUE about Y-linked disorders?
Usimov [2.4K]

Answer:

<em>The statement which is not true is C) They can affect males or females</em>

Explanation:

All the chromosomes in a person are known to be autosomal chromosomes except for the sex chromosomes. The sex chromosomes are of two types: Chromosome X and chromosome Y.

Both the sex chromosomes are X in females. Males have one X chromosome and one Y chromosome. The Y chromosome is shorter than the X chromosome. The Y chromosomes occur only in males. Hence, Y- linked disorders will affect only males. These disorders will never occur in females.
