What type of evidence would you look for in a natural setting to indicate that there is competition taking placle among the plan
alexdok [17]

In a study, competition among plants are normal. Hence, all plants required a few basic elements like the light, water, nitrogen, or phosphorus, depending upon the species and the location. Evidence that can conclude that competition do really happen in plants is that some plants release toxins into the soil, in their dropped leaves which wipe out the competition for soil nutrients (such as weeds). And when it come an area with many trees in close proximity such as a forest, height is also indicative of competition for light.

Which of the following statements about the smooth endoplasmic reticulum is/are correct?
olya-2409 [2.1K]

The correct answers are:

• Liver cells are abundant in SER.  

This is because liver cells contain enzymes that metabolize various lipid-soluble compounds.

• The testes and ovaries are tissue types whose cells are abundant in SER.

This is because testes and ovaries produce steroid hormones (cholesterol is the precursor for their synthesis).

• Cholesterol is made in the SER.  

ER is the organelle at which all membrane lipids are synthesized.

• Phospholipids are synthesized from cytosolic water soluble precursor molecules.  

Phospholipids are the main lipids that are the main structural components of the cell membrane. They are synthesized on the cytosolic side of the ER membrane, from water-soluble cytosolic precursors.
