The uninoculated tube is considered to be a negative control
because a negative control is an effect of having to show no response. Am uninoculated
control is where organisms are not being
inoculated such as having a culture bacteria of not being inoculated with an
organism.
Answer:
A) The radial orientation of cellulose microfibrils in the cell walls of guard cells causes them to bow outward and open when the stomatal pore when turgid.
Explanation:
Stomata are pores on the surface of leaves that work as valves controlling the gas exchange in plants; they are bordered by a pair of curved guarded cells in charge of opening and closing by increasing or decreasing the stomatal pore area.
Guard cells walls structure consist of a combination of stiff cellulose microfibrils oriented along the circumference of the cells and a softer matrix material which makes it possible for stomata pore to open by increasing water pressure (turgor).
Option B states that when guard cells become turgid, they close the stomata. This is a false statement as we explained before.
Option C states that light (known stimulant for opening stomata) causes guard cells to become flaccid which is also false. Guard cells become turgid in order to open the stomatal pore.
Option A is correct.

A large portion of the items originate from space rocks, which are objects made of different sorts of shake and have existed since the starting point of the nearby planetary group. A little rough or metallic lump of material that movements through space is known as a meteoroid. Small meteoroids (the measure of clean) are regularly alluded to as micrometeoroids or space tidy. These sections may likewise be extra comet flotsam and jetsam, or were shot out in impacts between other close planetary system bodies, such as mars.</span>
Answer:
The best answer to the question: These characteristics make primates particularly well adapted to what type of environment? Would be: the arboreal environment.
Explanation:
According to the video, primates, which subdivide into several groups, including the apes, from which also humans evolve, have, depending on their group, specific anatomical features and traits that allow them to survive in their environment. One such anatomical trait is the presence of larger brains than other mammals, long limbs, long fingers and strong lower limbs that allow them to adapt to tree life and survive in forest regions. Also, they tend to have a much more acute sense of vision due to their larger brain, but a much more limited sense of smell than other mammals. These characteristics become basic for them to live and survive in forest environments.
