Answer:
The correct answer is (b): Individuals with certain advantageous traits are selected, in the sense that they produce the most offspring.
Explanation:
Natural selection can cause a change in allele frequencies over time, making the best alleles, those better adapted, more common in the population over generations.
This is called Fitness, and it refers to how many offspring organisms of a particular genotype or phenotype leave in the next generation, relative to others in the group.
Natural selection can act on different alleles of a single gene, or on polygenic traits.
Natural selection can shift phenotype distributions in three ways:
-Stabilizing selection: Intermediate phenotypes are more fit than
extreme ones, e.g. camouflage.
-Directional selection: One extreme phenotype is more fit than all the
others, e.g. are more hidden in shadow and survive better than other
types.
-Disruptive selection: Both extreme phenotypes are more fit than those
in the middle, e.g. mimesis on octopuses.

Answer:
C. Carbon dioxide + water + heat
Explanation:
Answer:
Dams store water, provide renewable energy and prevent floods. Unfortunately, they also worsen the impact of climate change. They release greenhouse gases, destroy carbon sinks in wetlands and oceans, deprive ecosystems of nutrients, destroy habitats, increase sea levels, waste water and displace poor communities.
Explanation:
Answer:
A biotechnology researcher might work on creating biofuels (First option).
Explanation:
A biotechnology researcher, or <u>biotechnologist</u>, has the ability and tools to use organic matter and living beings for the manufacture of products, applying the technology.
A biotechnologist can work in the agricultural industry, pharmaceuticals, or developing products for environmental protection, such as biofuels.
Biotechnology is a <u>science applied to the manufacture of new and sustainable products, through molecular and biochemical research of organic material, plants and animals</u>, for this purpose.
The other options are not correct because:
<em> 2. The </em><u><em>design new hospital beds</em></u><em> depends on hospital engineering.
</em>
<em> 3. </em><u><em>Testing blood for diseases</em></u><em> are performed by a bioanalyst or laboratory technician.
</em>
<em> 4. </em><u><em>Using MRI machines</em></u><em> is performed by a radiologist or radiology technician.</em>
