Since color blindness is a sex-linked recessive genetic disorder, it is carried by a X chromosome. Males (XY) are affected if they get the affected X from their mother, since males only have one X, and it is therefore always expressed. Females (XX), however, get one X from their mother and the other from their father. So both parents have to pass a color blind X to be affected (both alleles, by the definition of recessive).
Even though the mother is not affected, she's carrying it because her father was color blind. And the father is not affected. However, in Turner's Syndrome, one X is destroyed after fertilization, so the other X is the daughter's primary (only remaining) X. Note: Turners only affects females. Therefore, this is a rare situation in which a daughter gets affected by an X-linked recessive condition.
Answer:
Becuase they break down and feed on organic molecules (the remains of dead organisms) and release inorganic molecules
Explanation:
The frontal lobe takes about 1/3 of the cerebral cortex.
Answer:
The correct answer is option - B. carbon dioxide.
Explanation:
Global warming is the rise in the overall temperature of the earth and its climate in the long term. It takes place due to the greenhouse gases emission that absorbs the heat and heat trapped in the atmosphere and increases the temperature of the climate system of the earth.
Greenhouse gases are the different gases that increase the temperature due to their ability to absorb and trap the heat that comes from solar light. The major source of the greenhouse gases is Carbon dioxide gas as its very small increase can affect and increase global warming to a different extent. Global warming has huge impact on earth and ecosystem as it increasing sea level by melting a glacier and other ways.
Thus, the correct answer is option - B. carbon dioxide
