GrogVix [38]

The right option is lateral corticospinal tract

The lateral corticospinal tract functions in the control of distal muscles such as those of the limbs and the trunk. About 90% of the fibers that travel in the corticospinal tract are found in the lateral corticospinal tract which makes it the main component of the corticospinal tract.

The sudden death of brain cells when their blood supply is interrupted is called
barxatty [35]
The only correct answer in this case is B - a stroke.

None of the other answers could be counted as correct here. 

While A - a heart attack is conceptualy similar, when we're talking about a heart attack, we're talking about not enough oxygen that gets delivered to the heart - because something is blocking it. 

C - hypertension on the other hand means someone has a higher blood pressure than is usual for a regular human being, which puts more strain on his cardiovascualr system. 

and D - atherosclerosis doesn't come even close to be correct :)

Cystic fibrosis is a recessive genetic disorder that result from a defective gene on chromosome 7. For an individual to have sym
spin [16.1K]

Answer:

Cystic fibrosis is a genetically transmitted or heriditary disease.

Explanation:

In cystic fibrosis the lungs and the digestive system get effected. It causes the CFTR protein (Cystic Fibrosis Transmembrane conductane Regulator) to become dysfunctional. Due to this dysfunction, chloride become unable to move.  for this reason mucus clogs the airways in the lungs which leads to respiratory failure and other complications. The gene responsible of this disease located at the long arm of chromosome number 7. Of all ethnic groups, caucasians have the highest inherited risk of this disease.

Describe the vascular system of plants. Include brief descriptions of the characteristics and function of xylem and phloem.
solong [7]

Answer:

The vascular tissue of the plants distributes water and nutrients, which guarantees a constant growth. Each newly formed cell needs to become the corresponding cell type in vascular tissue.

Explanation:

Like animals, plants need water and nutrients. While animals use a circulatory and digestive system to obtain and distribute nutrients, plants use a vascular system. This system absorbs water, vitamins and minerals from the soil and then transmits energy in the form of carbohydrates to the roots. The main components of the vascular system are the xylem and the phloem.

<u>Xylem</u> is a complex tissue formed by several cell types. Its function is the conduction of water and minerals from the root to the leaves. Among the cells that form this complex tissue differ:

- Conductive cells or tracheal elements: they are dead elements at maturity, they serve for vertical conduction and support

- Vessel members are observed in Angiosperms, the largest plant group with the most recent evolution; They are short, wide cells with thick secondary walls, they differ from tracheids because they are perforated elements.

- Storage elements: parenchymal cells, thick walls, secondary, can present crystals and other cellular contents.

- Support elements: fibers in the Angiosperms and fibrotracheids in Gymnosperms, elements of intermediate characters between the fibers and the tracheids.

<u> Phloem</u> cells conduct food (photosynthesis produced by photosynthesis) from the leaves to the rest of the plant. They are living cells at maturity and in histological preparations colored with Astrablue take the color blue. Phloem cells are located outside the xylem.

The sieve elements of this tissue are: the sieve cells in the Gymnosperms and the members of sieve tubes with their respective accompanying cells in the Angiosperms. The accompanying cells retain their nuclei and control the neighboring sieve tubes. Dissolved food, such as sucrose, circulates through the screened areas that connect these cells to each other.

Being a complex tissue, it also has parenchymal cells for storage and fibers and sclereids as a support.
