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.

Describe how changes in an ecosystem can affect organisms that live there..
Shtirlitz [24]
Well it really depends on what kind of change there is. For this I'll use a drought as an example. If a drought occurs in an area the plant life and vegetation will start to die off in that area. From there, primary consumers would run out of food. then secondary consumers, and so forth and so on. it'd be like putting a cow in a field of dirt with no food and a large bucket of water. Eventually the cow will die of starvation. Now apply this to all of the animals in that ecosystem.

When antibodies bind antigens, the clumping of antigens results from _______. A. the antibody having at least two binding region
Pani-rosa [81]

When antibodies bind antigens, the clumping of antigens results from the antibody having at least two binding regions.

What's the function of the antibody-antigen complex?

Antibodies serve two primary functions: selective binding to antigens to initiate an immune response and activation of other immune system components to combat infections.

  • Immunoglobulins' capacity to combat a wide range of diseases is based on their inherent ability to distinguish between distinct antigens.
  • Because of their antigen specificity and affinity, antibodies have shown to be a significant and important tool in research, diagnosis, and treatment.
  • Although it appears to be a straightforward move, the connection of an antibody and its antigen to form an antigen-antibody complex is made up of a plethora of non-covalent interactions.

Hence, the correct answer is option A
