Answer: By Hormonal action and Nervous coordination
Explanation:
Hormones are substances produced by one tissue and conveyed by the bloodstream to another to effect physiological activity. Homeostasis is the maintenance of a stable internal environment in the body.
Body systems such as digestive, circulatory, excretory systems etc, all are coordinated to achieve a STABLE INTERNAL ENVIRONMENT by the aid of HORMONES AND/OR NERVOUS COORDINATION.
For Example: the vasodilation of blood vessels during hot weather, and the opposite action of vasoconstriction during cold weather are both controlled by Hormonal action and nervous coordination which leads to a stable body temperature preventing excess heat accumulation.
Also, Nervous system controls the body systems, such that the muscle contractions are joined to actions like sweating, breathing, respiration etc
So, to maintain homeostasis hormonal action and Nervous coordination is necessary.
Organisms need energy to conduct essential life activities. Basically, energy is essential to every organisms because it is their source of power to get food and to reproduce. Without it, organisms would not function properly and will soon die.
I believe the inability to make saliva would affect digestion drastically. The first phase in the process of digestion comes with saliva - it breaks down some substances in your mouth, because it contains amylase which helps during this process. If it weren't for saliva, you probably wouldn't even be able to swallow food - and even if you did, it would be almost impossible to break it down in your body.
The probability that they both were planted alone is 0.3325.
<h3>What is genetic probability?</h3>
Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck.
In this case:
- Number of plants planted alone = 134
- P(both plants were planted alone) = 134/232 x 133/231 = 0.3325
So the probability that both were planted alone is 0.3325.
