Which term refers to the stages an organism goes through, from birth to death?
Verdich [7]
The answer is A because in a life cycle it start of in birth, then growing up, then adult then giving birth and then death. after death or birth the life cycle starts all over again. but in actuality when it gives birth that's when the life cycle is restarted. think as it's us humans. we are born. after that we grow up to be a toddler - young kid => teenager => young adult => then women gives birth => new baby is born. when new baby is born then the life cycle is restarted. but the next step after a baby's born the mom and dad get old and then death is the last step.<span />

The ileum contains ________ that project into the lumen and increase the amount of surface area.
Ivanshal [37]

The ileum contains villi that project into the lumen and increase the amount of surface area.

Villi are small finger-like structures that project into the lumen of the small intestine. Villi increase the surface area of the intestinal walls for easy and quick absorption of digested food with the addition of digestive secretions. Villi vary in length from about 0.5 to 1 mm. They are usually found in large numbers at the beginning of the small intestine and they reduce toward the end of the tract.

Bezzdna [24]

Answer:

four phenotypes appear in the ratio 9:3:3:1

Explanation:

<em>For a dihybrid cross in which the two genes concerned obey simple dominant/recessive law and are independently assorting, </em><em>four phenotypes are produced in the ratio 9:3:3:1. </em>

The dominant gene takes up the largest ratio (9/16) while the recessive gene takes up the smallest (1/16). Any deviation from 9:3:3:1 and the number of phenotypes produced from a dihybrid cross is an indication that the genes involved do not obey Mendelian laws.
