The prairie meadow mice are large eaters, eating their own weight in greens every twenty-four hours. Usually they eat tender stems, leaves, roots, tubers, flowers, seeds, fruits or grasses,The meadow mice helped by cutting down the grass and by loosening the soil with their tunnels.By making tunnels, the mice also continuously mix wastes and their food stores with the soil. In this way the nutrients from the food they eat are quickly returned to the soil.
Two different types of succession—primary and secondary—have been distinguished. Primary succession occurs in essentially lifeless areas—regions in which the soil is incapable of sustaining life as a result of such factors as lava flows, newly formed sand dunes, or rocks left from a retreating glacier.
Answer: XHXh (Note: the H's are superscripts.)
Explanation:
Hemophilia is a sex-linked recessive trait which means that the males having one altered copy of the gene is enough to cause the medical condition( as they have only one X chromosomes and females have two)
In this case the genotype of father and son is such that they are affected by hemophilia.The son has mother's X chromosome and father's Y chromosome.
XhY is the genotype of father and son. As mother would be heterozygous because she is not affected, her genotype will be XHXh.
Answer: Option C) C. They are composed of misshapen proteins
Explanation:
Prions are infectious agents that contain protein but no nucleic acids (DNA or RNA). Prions have been implicated in the causative agent in several diseases such as:
- Mad cow's disease
- Creutzfeldt-Jakob disease etc
The Prokaryotic cells lacks nucleus when DNA is loose inside and is made of a single loop. Hope this helps mate :)
