Answer:
Reproductive isolation, as well as taxonomic and genetic differences, can be used to discover and classify new species
Explanation:
According to the biological concept of species, "the species can be recognized to be reproductively isolated by morphological, behaviors and physiological processes that prevent interbreeding with other groups". These differences can include taxonomic changes and the lack of homology between conserved genes, which enable us to discern that two individuals belong to different species. In genetics, for example, the mitochondrial gene Cytochrome Oxidase I (COI) is widely used to differentiate between species because it is evolutionarily conserved, thereby important sequence differences may indicate that two individuals belong to different (even cryptic) species.
C. Photosynthesis which is a process of converting water and carbon dioxide into carbohydrates using sunlight. Nitrogen is not involved.
Answer:
Small and lipid soluble cortisol can pass through nonpolar core of the plasma membrane.
Explanation:
Cortisol is a lipid-soluble steroid hormone with a compact structure. The plasma membrane is a bilayer of phospholipids.
The phospholipids are amphipathic molecules with a polar head and nonpolar tails. The nonpolar tails of the two layers of phospholipids are packed away from the watery medium and make the core of the plasma membrane.
Being a lipid-soluble hormone with a small structure, cortisol can pass through the nonpolar core of the plasma membrane easily to activate its receptors and alter the gene expression.
