Answer:
A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.
Explanation:
Phenotypic plasticity might be understood as the ability of a genotype to produce different phenotypes in response to varying environmental conditions.
Phenotypic plasticity needs epigenetic mechanisms to occur, which involve the genotype and the environment interaction to produce adapted phenotypic changes.
Epigenetic mechanisms produce changes in the expression of the genes, with no need to alter the DNI nucleotides sequences.
A heterogeneous environment imposes variability on genotypes that interact with it, producing different phenotypes. These phenotypes will vary according to environmental conditions.
The answer is a drug-resistance.
In natural selection, genotype variations that
will increase the chance of survival and reproduction of some organism are
preserved and will be inherited. The drug resistance is the trait that increases the chance of bacterial survival and reproduction.<span>Thus, if there are pathogens with drug-resistance and pathogens without drug-resistance, then natural selection will favor those pathogens that are drug resistant. </span>
Answer:
We only see the Moon because sunlight reflects back to us from its surface. During the course of a month, the Moon circles once around the Earth. If we could magically look down on our solar system, we would see that the half of the Moon facing the Sun is always lit. But the lit side does not always face the Earth!
Explanation:
Answer:
A saturated fat is a type of fat in which the fatty acid chains have all or predominantly single bonds. A fat is made of two kinds of smaller molecules: glycerol and fatty acids. Fats are made of long chains of carbon atoms. Some carbon atoms are linked by single bonds and others are linked by double bonds. Double bonds can react with hydrogen to form single bonds. They are called saturated because the second bond is broken and each half of the bond is attached to a hydrogen atom.
