Answer:
C. His mother carried at least one allele for that trait
Explanation:
-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father.
-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.
-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.
D
Unlike carbon-based fuels like coal, natural gas, and petroleum, nuclear energy does not release greenhouse gases into the atmosphere. Therefore it does not contribute to global warming.
Explanation:
Nonetheless, nuclear energy is not widely adopted for energy because of its safety concerns. Fission energy is harmful to the environment because of nuclear waste it generates. How this nuclear waste is stored is very important because leakage can lead to contamination of an environs with lethal radioactive elements.

A gas is one of the three states of matter on earth and in the universe.
Gases are easily compressible and they can fit into just any container available.
This is because of their fascinating properties.
- The particles of gases are very far apart and are held together by weak attractive forces unlike liquids and solids.
- Gases are always in constant motion and their particles are random.
- They do not have a fixed shape and structure.
- When pressure is applied on them, they are easily compressed and fit into any container they are placed.

The answer is <span>A. The two animal species are very closely related.
If the two animal species are very closely related, that means their genome information is very similar and that information for embryonic development is also very similar, but it will not be identical. Stages of embryonic development from the beginning to the end are same only in the same species. In different species, they will differ in lesser or greater extent which depend on how closely this different species are related.</span>
