Less reproductive isolation among populations that share similar habitats
<h3>What is Reproductive Isolation?</h3>
The reproductive isolation mechanisms are a set of evolutionary mechanisms, behavioral, and physiological processes that are essential for speciation.
They either prohibit individuals of other species from having children or guarantee that any children are infertile. When individuals or groups diverge in the time of various behaviors, such as foraging or mating, reproductive isolation can arise.
Toad species Bufo americanus and Bufo fowleri exhibit reproductive isolation due to changes in mating season. Members of these species can successfully cross in the lab, resulting in healthy, viable hybrids. Temporal isolation, ecological isolation, behavioral isolation, and mechanical isolation are the three modes.

Answer:
Cytokinesis, or “cell motion,” is the second main stage of the mitotic phase during which cell division is completed via the physical separation of the cytoplasmic components into two daughter cells. Division is not complete until the cell components have been apportioned and completely separated into the two daughter cells. Although the stages of mitosis are similar for most eukaryotes, the process of cytokinesis is quite different for eukaryotes that have cell walls, such as plant cells.
Explanation:
Stress response by the body is regulated by the nervous system. As the day of the exam draws by, the cerebral cortex of the student activates the hypothalamus that triggers hormones to be released that activates the systemic branch of the autonomic nervous and endocrine system (Larissa, 2018). The autonomic nervous system controls involuntary bodily responses such as breathing, heartbeat, and digestion. The endocrine system contains glands that secrete hormones into the bloodstream that regulate the functions of body organs. The student's pituitary gland in response to the activated hypothalamus, which would secrete a hormone which in turn triggers the release of stress hormones from the adrenal glands and it would help the student manage stress by making nutrients available to meet the demand for energy. These hormones activate the sympathetic division of the autonomic system, causing increased heart rate, breathing, and blood pressure and the suppression of digestion (America psychological association, 2019). After the exam, the student is restored to a less tressful state. The parasympathetic branch of the autonomic system would slow the student's heartbeat and breathing and digestive processes would no longer be suppressed and the student gains appetite for food (BcCampus, 2019).
Answer:
There are four principles at work in evolution—variation, inheritance, selection and time.
Explanation:
These are considered the components of the evolutionary mechanism of natural selection. ... Selection Some individuals have inherited character (genes) that allows them to better survive or produce more offspring
