Answer:
Object C
Explanation:
Object A has two arrows, one pointing up and one pointing down. Since both arrows are the same length, the forces cancel, and Object A will not move.
Object B also has two arrows, one pointing up and one pointing down. However, the downwards pointing arrow is much longer than the other. This means it has more force and the object will move down.
Object C has two arrows, one pointing up and the other down. However, the upwards pointing arrow is longer than the other, meaning it has more force and the object will move upward.
Object D has two arrows, but both are pointing downwards, meaning the object will move down.
A plant was placed in water containing black dye. After 24 hours the
plant was removed and sections were taken from the root and the
stem. In the root, cambium part will get stained and in the stem, cortex will be stained from dye so the correct option is D.
<h3>
What is cambium and cortex in plant root and stem?</h3>
Cambium is a layer of continuous dividing cells between xylem and phloem tissues which is responsible for the secondary growth of stems and roots. A cortex is an outer layer of a root or stem in a plant, located below the epidermis but outside of the vascular bundles.
The conduction (uptake) of water in a plant stem takes place through the xylem.

Answer:
The answer is NITROGENOUS WASTE.
Explanation:
The urinary tract filters wastes and water from the blood, and eliminates them from the body.
UREA which is a nitrogenous byproduct of the decomposition of protein metabolism in mammals, is also released into the blood stream and to the tubes, after being broken down by the LIVER. All waste mixes with the filtrate to form urine
Urine is then collected in a duct and excreted through the bladder.
