Answer:

Release of adrenaline by the adrenal glands.

Explanation:

Adrenaline hormone also known as epinephrine is an important part of sympathetic nervous system. It is released from adrenal medulla through a sequence of events in a situation of "fight or flight" or we can say in a life threatening situation. This hormone causes our muscles to perform vigorous activities so that body could respond accordingly. Chemically adrenaline hormone is synthesized by using "tyrosine" as a precursor which after a series of enzymatic actions gets converted into L-dopa and then dopamine then nor-adrenaline and finally into adrenaline.

Can someone pls help me<br>​
Black_prince [1.1K]

Answer:

16. mitochondria

17. lysosomes

18. smooth Endoplasmic Reticulum

19. golgi body

20. golgi complex

Explanation:

16. Mitochondria are double membrane-bound cell organelles responsible for the supply and storage of energy for the cell

17.  While cells mainly use lysosomes to dispose of trash. Sometimes they simply hang onto their trash, performing the cellular equivalent of sweeping it under the rug

18. Are the storage organelle, associated with the production of lipids, steroids, and also responsible for detoxifying the cell.

19.  The Golgi body is the sorting organelle of the cell. Proteins are transported from the rough endoplasmic reticulum (RER) to the Golgi.

20. is responsible for sorting and correctly shipping the proteins produce the ER. Just like our postal packages, which should have a correct shipping address, the proteins produced in the ER should be correctly sent to their respective address. It is a very important step in protein synthesis.

Which of the following is the most likely flow of energy in an aquatic ecosystem?
Klio2033 [76]

Answer: b. phytoplankton ® zooplankton ® fish ® mammal

Phytoplankton are single celled organisms they are included in the category of bacteria, protist or algae living in an aquatic biome. They are autotrophic in nature. Examples are cynobacteria, diatoms etc.  They are abundant in number and maintains the lowest level in aquatic food chain, they are the primary producers as they can produce their own food. This level has the highest energy in the aquatic food chain. Zooplankton are aquatic organisms which are heterotrophic in nature. They are dependent upon plants and other aquatic organisms for their living. Examples Dinoflagellates, Cnidarians, Crustaceans, Chordates, Molluscs etc. They are the primary consumers in the aquatic ecosystem. Fishes are dependent upon both phytoplanktons and zooplanktons for their food requirement, they are dependent upon primary producers and primary consumers. Therefore, they are secondary consumers in the aquatic food chain. Lastly, mammals feed on fish are tertiary consumers. Therefore, energy will flow from primary producer to primary consumer, then to secondary and tertiary consumers. The lowest level in food chain will attain largest energy and the highest trophic level will attain the least energy. This is in accordance with the 10% law which says that energy decreases at each subsequent trophic level starting from the bottom.

Hence, the energy will flow in phytoplankton ® zooplankton ® fish ® mammal
