Answer:
ENDOCRINES circulate in the blood and act at sites distant from their origin;
EXOCRINES pass through ducts;
and PARACRINES act on their local tissue environment.
Explanation:
Exocrines are known for producing external secretions that are released through a duct, usually into the digestive system or the skin
Endocrine are known for producing internal secretions called HORMONES that are transported around the body by the bloodstream. They are also called ductless glands.
Paracrines are known for producing hormones that act on his immediate location or producing gland
The energy available for the second-level consumers is <u>4756.5 </u>kilocalories.
A trophic level is a position in the food chain or nutrient cycle of an ecosystem. Based on their eating habits, organisms in a food chain are divided into various levels. The first trophic level is usually occupied by producers that can synthesize their own food.
The efficient energy transfer from one trophic to another is only 10% rest of the energy is lost in the ecosystem. The studies of the transfer of energy in different food chains in a large number of ecosystems have revealed a uniform pattern, which is stated as the 10 percent law by Lindemann. According to this law, only 10 percent of the energy entering a particular trophic level of organisms is available for transfer to the next higher trophic level.
Calculation:
Producers (475650 kilocalories) —> Primary consumers (10% of 475650 = 47565 kilocalories) —> Secondary consumers (10% of 47565 = 4756.5 kilocalories).
So, the energy available for second-level consumers is 4756.5 kilocalories.

The answer is: D. Passive transport
Passive transport refers to the movement of chemical substance that pass through the cell membrane without using any energy, This ability exist in all living cells and utilizing the process of osmosis to move from a less concentrated environment to a more concentrated one.
Based on the salient features and the laboratories of this patient, this is a case of Crohn's disease. Crohn's disease is type of chronic inflammatory bowel disease or IBD along with ulcerative colitis. Crohn's disease usually presents with diarrhea, abdominal pain, and significant weight loss. Pathologically, it is characterized by "skip-lesions" or discontinuous granulomatous that occurs on all layers of the bowel (transmural); with the involvement of the whole gastrointestinal tract. Patients with Crohn's disease have a significant risk in developing colorectal cancer.
