Epidermis of plant root systems is most responsible for their ability to absorb water and mineral nutrients efficiently.
<h3>How do plants take up nutrients and water?</h3>
The xylem, a tissue made up of tiny tubes found just below the surface of the plant's stems, is where plants collect water and nutrients. The water is drawn upwards by the molecules in this tissue, which draw water molecules from the soil. We refer to this mechanism as capillary action.
Root hairs are single celled and large surface area , perfect for absorption of water and nutrients. Root hairs are long thin, single cell extension from the epidermis.

The Earth and Moon compare in terms of gravitational force as Earth's gravitational force is stronger than the Moon's.
Option A
<u>Explanation:</u>
According to universal law of gravity, the gravitational force is the attractive force between two objects separated by a distance. The magnitude of gravitational force is directly proportional to the product of masses of the objects and inversely proportional to the square of the distances between them.
In this case, the gravitational force acting on us due to Earth will be considered due to the mass of Earth as the mass of Earth is very large compared to our mass.
So as the mass of the Earth is greater than the mass of the moon, so the gravitational force of Earth will be stronger than that of Moon.

The receptors for steroid hormones are reside inside the cell instead of the membrane surface, like most other signal receptors. So, Steroid hormones are lipid soluble. Steroids gain access to their receptors because they can readily diffuse through the lipid bilayer of the cell membrane.
Steroids are man-made hormones which are lipid soluble and are normally produced by our adrenal glands, which are two small glands always found above the kidneys. When steroids are taken in higher doses than the amount your body normally produces and that steroids reduce redness and swelling.
Therefore, steroid harmone signalling is a lipid-soluble signalling which can be transmit through the bloodstream from an endocrine gland bound by a steroid binding protein (SBP).

Answer:
X: plant material
Y: meat
Explanation:
Just look at the molars: One is obviously for eating meat, as the jaws in the front are sharp and can easily shred meat. One is for chewing plants, as it's molars are flat.
