Answer:
C. On average, 25% of the children are affected by the autosomal recessive disease if both parents are carriers.
Explanation:
A recessive trait is always expressed in homozygous genotype only. To have progeny with recessive traits from two normal parents, both the parents should be heterozygous carriers. For example, two normal parents with genotype "Aa" have 25% of the chances to have a child with homozygous recessive genotype (Aa x Aa = 1/4 AA: 1/2 Aa: 1/4 aa).
An autosomal trait is equally expressed in both males and females. Inbreeding increases the homozygosity and thereby, increases the risk of expression of recessive traits which are otherwise masked in heterozygous genotype.
Answer:
Living organisms that are heterotrophic include all animals and fungi, some bacteria and protists, and many parasitic plants. The term heterotroph arose in microbiology in 1946 as part of a classification of microorganisms based on their type of nutrition.

Answer:
Revolution of earth around the sun
Explanation:
Heat's effect on the wind cycle is most easily observed near the sea. During the day, the ocean absorbs heat from the surface, keeping the air above it cooler than above the land. When the warm air rises from the shore, the cooler air from the ocean blows in to take its place. At night, the land cools quickly, while the ocean radiates the heat it absorbed, keeping the air above warm. This reverses the effect, causing the air offshore to rise and creating a breeze from the land. Uneven heating can also occur due geographical features. A mountainside exposed to the sun will warm more than a shadowed valley below it, creating a wind that blows uphill during the day and downhill at night.
The same principle is responsible for global wind patterns. The polar regions receive less solar radiation than areas near the equator, resulting in a global shift in temperature according to latitude. This, along with differences in temperature and density in various layers of the atmosphere, creates global wind patterns like the jet stream that help drive weather systems.
Hope this helped
