D. Plants have adapted to deal with the sun in many different ways, and this is one. The stomata are regulated by guard cells, which are activated by different things depending on the species of plant, and guard cells are supposed to keep the stomata from staying open all the time and losing too much water to evaporation. So, the solution is to have the stomata on the bottom of the leaf to prevent direct sunlight contact (and therefore more evaporation), and guard cells to protect the stomata.
Pair-bonding in a population of prairie voles can be prevented by . B) administering a drug that inhibits the brain receptor for vasopressin in the central nervous system (CNS) of males
<h3>
what is pair bonding?</h3>
Pair bonding is an evolutionary feature that may be important for reproduction as well as individual and species survival.
The proximate processes underlying many types of good social behaviours, such as pair bonding and maternal-infant behaviour, are shared by brain and endocrine systems.
The brain systems that rely on peptides, such as oxytocin, vasopressin, opioids, CRH, and associated hormones, are at the heart of pair bonding.
Neuropeptides also help to integrate the autonomic and endocrine effects of pleasant social encounters with behavioural states that promote social bond creation and maintenance.
