This question is incomplete because the options are missing; here is the complete question:
A co-worker was sanding an object on a belt sander when he slipped. He has an abrasion on his elbow that is about 3 inches long 2 inches wide. The wound bled a little at first but has stopped. What type of bleeding is this most likely to be?
A. Capillary
B. Venous
C. Arterial
D. Both venous and arterial
The answer to this question is A. Capillary
Explanation:
Capillary bleeding is the least serious bleeding, this occurs in superficial wounds including abrasions, and in most cases, this type of bleed will stop after some minutes without any intervention. Moreover, this bleeding is caused due to the damage of capillaries, which are very small blood vessels.
Capillary bleeding is most likely the bleeding in the co-worker because the injury was mainly superficial and the bleeding stop after some minutes. Also, the blood loss was minimal, which occurs in capillary bleeding but not in arterial or venous bleeding.

The correct answer is option E. only water-soluble hormones use second messengers.
Explanation:
Water soluble hormones can not diffuse through cell membranes as only lipid soluble molecules can pass through the cell membranes and these hormons are not lipid soluble molecules,
These water hormones are usually glycoproteins, peptide and catecholamnies such as TSH, FSH, LH and insulin. these hormones need second messengers because there receptors are present on the plasma membrane.
Thus, the correct answer is option - e. only water-soluble hormones use second messengers.
