The xylem is made from dead, hollow cells.
<span>
Tracheids and vessel elements are the main components of xylem witch have a function to transport water. Those are elongated dead cells at maturity (without protoplast) with a thick, strengthened cellulose cell wall and a hollow lumen. Even though they are dead they still maintain a function, because are being protected by surrounding living cells.</span>

Answer: dead long hollow tubes.

Explanation:Because when xylem cells are first formed a chemical called lignin is deposited in spirals in the cell wall causing the cells to die and leave long hollow tubes which allow the movement of water and mineral ions through for healthy plant growth

Brian hamilton has , which is an inflammation of the tissues surrounding his elbow. this was caused by a sports injury.
KIM [24]
This is called bursitis specifically olecranon bursitis. Olecranon bursa in the elbow is a thin fluid filled sac at the tip of the elbow. The bursa fills with fluid which can lead into inflammation on the surrounding area of the elbow resulting in pain and limitations of movement. Complications can happen if medical attention is not given. This includes bleeding, bruising, infectins, necrotizing fasciitis can also happen. Patient must undergo work up such as plain x rays, bone scintigraphy or if needed MRI/CT scan. Surgical interventions are usually needed because non surgical means are usually non effective. Long term monitoring is a must and patient must be advised on prevention practices.

The dominant allele is for black fur. The recessive allele is for white fur.
Leokris [45]

Answer:

FF , Black fur.

ff, white fur.

Explanation:

Genotype may be defined as the genetic constitution of the organism whereas phenotype depends on the genotype for the physical expression of the trait.

Let the genotype of the dominant fur (black ) be D and the genotype of white fur (recessive)  is f. homozygous means the individual should have the same allele for the trait. A mouse with homozygous dominant has genotype FF . This mouse has black fur. A mouse homozygous for the recessive trait has the genotype f. This mouse has white fur.

Thus, the answer is FF , Black fur.

ff, white fur.
