The answer that best completes the statement above is this: Activation of factor X, leading to conversion of prothrombin II to thrombin IIa. This is the final step in both pathways. The thrombin, which is an enzyme in the blood plasma, does the conversion of fibrinogen (I) to fibrin (Ia). This is the one responsible in clotting. The intrinsic pathway is initiated by <span>Factor XII. On the other hand, tissue factor during injury initiates the extrinsic pathway. </span>

2. Copy/paste and align the first 5 bases of all introns. Which bases are conserved near intron start ("donor site")?
Delicious77 [7]

Answer:

This question is incomplete

Explanation:

Introns are non-coding regions of a DNA that removed by RNA splicing prior to translation. Alignment is usually done between sequences to see and understand the identity and similarity between two or more sequences.

A region/base is said to be conserved if there is  NO change in any base in that particular region. A multiple sequence alignment (MSA) can be used to align the donor sites of all the introns to see the bases that have not "changed" (and still remained in there exact position) hence conserved across all the donor sites.

NOTE: The donor site of an intron is the 5' end, thus the first five bases in the 5' end are to be used here

mote1985 [20]

Answer:

Answered below

Explanation:

Head injuries may be penetrating head injury or closed head injury.

A major concern for health professionals regarding intracranial injuries resulting from closed head traumas, is the management of intracranial pressure. Elevated intracranial pressure have negative effects on the brain and immediate management of raised intracranial pressure is important to avoid cerebral edema, intracranial hematoma, brain herniation and even death.

The usual procedures in the management of head injury include elevating the head to about 30 degrees. This position promotes cerebral venous drainage and decreases intracranial venous pressure and intracranial pressure as well.

This is helpful because when the patient is left in the horizontal position, the intracranial pressure becomes significantly higher and the have fatal consequences.

What is the difference between a lake and a pond? a. A pond is smaller in size and does not have a temperature gradient. b. A po
Ksju [112]

Answer:

I think the answer is A.

Explanation:

Ponds and lakes are both inland bodies of freshwater that contain living creatures. Lakes are normally much deeper than ponds and have a larger surface area. ... All the water in a pond is in the photic zone, meaning ponds are shallow enough to allow sunlight to reach the bottom.

  The yearly process known as thermal stratification. A pond that is thermally stratified simply means that there is a noticeable temperature gradient as the water gets deeper. You may have noticed this in summer while swimming.
