What is color blindness?
Color blindness is a disability in which you are unable to see colors normally. Color deficiency is another name for it.
It is a condition in which a person is unable to distinguish between different colors.
The most common colors are greens and reds, but it can also happen with blues.
This condition is only dominant in males, but females carry this disability as recessive carrier, so they can transfer this gene to the next generation.
Thus, option (B) she is a carrier for color blindness is correct.

B,
since males only need one recessive trait for it to show, and the father is not colorblind, the mother at least has to be a carrier for the colorblindness trait.

Although all systems in the body are interrelated and impact one another, the systems that have the most important roles in regulating blood pressure are the ones in B. The circulatory, obviously, is the most important because it consists of the heart, blood vessels, and blood. When the heart pumps blood, it creates pressure on your arteries. These processes are communicated throughout your body using the brain or nervous system. The respiratory system also works closely with the circulatory system because when oxygen enters the blood, it travels to the heart and is pumped to the rest of the body.

The downfall of a tragic character is the result of "a tragic flaw".
The term hero is gotten from a Greek word that implies a man who faces affliction, or shows strength, despite risk. Nonetheless, at times he faces ruin too. At the point when a hero goes up against destruction, he is perceived as a tragic hero. Aristotle, the Greek philosopher, portrays these plays or stories, in which the principle character is a shocking saint, as disasters. Here, the hero goes up against his ruin whether because of destiny, or by his own oversight, or some other social reason.

Answer:
A). Placenta
Explanation:
During pregnancy, the embryo formed as a result of zygote growth produced from fertilization is implanted in the UTERUS or WOMB of the female. The developing fetus is strictly dependent on the mother for all the substances it needs to survive. These substances reach the fetus via a structure present in the uterus. This structure is called PLACENTA.
Placenta is the connection between the mother and the developing fetus. It is an organ that helps the mother supply required nutrients and oxygen via the umbilical cord to the fetus. It also helps remove waste products from the fetus into the mother's blood. Hence, the PLACENTA is the site of nutrient and gas exchange (oxygen and CO2) between the mother and the fetus.
