A substance that influences the reaction but does not participate in the reaction is
Sedbober [7]

Answer:

a catalyst

Explanation:

Catalyst is a substance that influences the rate of reaction without being consumed in the reaction. They increase the rate of reaction by decreasing the activation energy of the reaction. In biological system, enzymes are referred to as biological catalyst or biocatalyst. They are generally protein in nature and are very specific for their substrate. They also increases the rate of biological reaction by forming enzyme-substrate complex.

hope this helps and have a good day :-)

1. The sensory layer of the eye.
Keith_Richards [23]

Answer:

The correct answers are:

1. The sensory layer of the eye. B) Retina

2. The structure most responsible for focusing light rays that enter the eye. D) Lens

3. Helps maintain the intraocular pressure; located in the anterior part of the eye. A) Aqueous humor

4. Area of greatest visual acuity. C) Fovea centralis

Explanation:

1. The sensory layer of the eye.

The retina covers the inside of the eyeball. It is considered as the sensory organ of the eye, where the perceived images are projected, are processed in the form of a nerve impulse that leaves the optic nerve.

2. The structure most responsible for focusing light rays that enter the eye.

The lens are the transparent structure inside the eye that focuses light rays in the central part of the retina.

3. Helps maintain the intraocular pressure; located in the anterior part of the eye.

The aqueous humor, is a transparent aqueous fluid secreted by the ciliary body, this liquid derived from the blood plasma, distributes oxygen and nutrients to the upper part of the eye and eliminates residual products. The dynamics of production and elimination of aqueous humor is very important to keep intraocular pressure (IOP) within normal limits.

4. Area of greatest visual acuity.

The fovea, or also known fovea centralis, is the center of the visual field, it is a narrow area of the retina that only contains cones. Its function is to help us have a vision as clear as possible with all kinds of details and precision.

Sort the examples into proper mechanisms of reproductive isolation.
vovangra [49]
The mechanisms of reproductive isolation prevent the reproduction of two individuals from different species. The prezygotic mechanisms disrupt the stages of reproduction before the forming of the zygote or prevent the mating at the start, and the postzygotic mechanisms affect the stages of reproduction after the forming of the zygote.
So, the first and the third example (the urchins and the grasshoppers) show the prezygotic mechanism, as the two individuals are not able to mate or form a zygote.
The second and the fourth example ( zonkey and the death of a zygote) show the working of the postzygotic mechanisms, as the zygote is formed, but it seems to be inviable, and the zonkeys are sterile, preventing the individual to reproduce.
