Answer:
First, it's important to get clear on the meaning of Homeostasis.
In simple terms, it refers to the capacity of a living thing (plant or animal) to react or behave in such a way that enables it to continue to survive irrespective of changes in its immediate environment.
Explanation:
In humans, the body has a system which reacts to the external stimuli of temprature. When the weather is hot, the brain through a sequence of electrical and chemical signals tells the skin to open up the pore, then we experience venting of sweating which cools the body and regulates internal heat. This is an instance of homeostasis.
This does not mean that the plant or animal is completely immune to such external changes.
In the case of the tomato plant, the hair on the leaves and stem of the plant is an example of Homeostatic responses which have evolved over the years to discourage predators such as the hornworm caterpillar from defoliating the plant.
Cheers!
Answer:
a. different alleles of the seed shape gene.
Explanation:
Mendel crossed different varieties of pea plants and he observed how phenotypic traits passed to the progeny. From these experiments, Mendel formulated the 'First Law of Segregation', where he observed that traits may exist in pairs that segregate (separate) at meiosis. During meiosis, i.e., gamete formation, these two factors separate from each other, thereby each gamete has the same probability of receiving either factor. Nowadays, we know that these two factors represent two different gene variants or 'alleles' for a given gene <em>locus</em>. Alleles can be classified into dominant or recessive as in the example above described, where the R factor (round) dominates on the r factor (wrinkled) to determine the seed shape.

Sensory neurons and motor neurons are only two of the basic types of neurons. The basic function of neurons are in transmitting nerve impulses to the different parts of our body. Sensory neurons<span> carry signals from peripheral parts of our body into the central nervous system. On the other hand, m</span>otor neurons<span> carry impulses from the central nervous system to the peripheral parts of our body.
Best answer: </span><span>sensory neurons carry stimuli information to the brain; motor neurons carry processed information to muscles and glands. </span>
