Answer:
Thermodynamics
Explanation:
By definition, thermodynamics is the study of energy transformation that occur in a collection of matter.
Answer:
True
Explanation:
B cells are involved in the humoral immune response and T cells are involved in the cell-mediated immune response. Class 1 MHC molecules are found on all uncleared cells and class 2 MHC molecules are found on macrophages, B cells, and activated T cells.
Since all cells in our body contain DNA, there are lots of places for mutations to occur; however, some mutations cannot be passed on to offspring and do not matter for evolution. Somatic mutations<span> occur in non-reproductive cells and won't be passed onto offspring. For example, the golden color on half of this Red Delicious apple was caused by a somatic mutation. Its seeds will not carry the mutation.

A single germ line mutation can have a range of effects:
<span><span>No change occurs in phenotype.
Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein.</span><span>Small change occurs in phenotype.
A single mutation caused this cat's ears to curl backwards slightly.</span><span>Big change occurs in phenotype.
Some really important phenotypic changes, like DDT resistance in insects are sometimes caused by single mutations. A single mutation can also have strong negative effects for the organism. Mutations that cause the death of an organism are called lethals — and it doesn't get more negative than that.</span></span>
<u>Answer</u>: c. Natural gas.
<u>Explanation</u>:
- <em>Natural gas</em> is a fossil fuel and thus a<em> non-renewable resource.</em>
- Natural gas is widely used for the purpose of heating, cooking, and generation of electricity.
- The process of formation of natural gas takes place over millions of years from decomposing plant and animal material subjected to heat and pressure.
<em>Thus, natural gas cannot be used for the conservation of resources.</em>
Answer:
Exhibit the disease
Explanation:
A dominant trait is a trait that appears visible due to dominant genes in the individual.
If the disease is due to a completely dominant mutation then such a disease will be fully exhibited. However if the disease was caused by a completely recessive mutation then the disease won’t be fully exhibited.
