When dry environmental conditions exist, guard cells close the openings in leaves to reduce the loss of water from the plant. this process is an example of a feedback mechanism that plants use in order to a. produce more chlorophyll. b. absorb more solar energy. c. maintain homeostasis. d. expend their resources.

C. maintain homeostasis.

Explanation:

A stoma is formed by the guard cells and the ostiol, a small opening. It is this opening that connects the external environment to the interior of the plant's tissues, an intercellular space called the sub-stomatic chamber. By controlling the opening and closing of ostioles, the plant is able to control homeostasis within the leaf, by controlling the entry of gases and preventing exaggerated water loss. In this way, the plant allows the complete balance of your organism.

in situ hybridization has been widely used for research applications, including clinical cytogenetics, gene mapping, tumor biology and studies of chromosome evolution.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.
