Answer:

c) Ribosomes on the rough endoplasmic reticulum; Golgi apparatus

Explanation:

Endoplasmic reticulum, a member of endomembrane system. If it contains ribosomes on their surface, they are called Rough Endoplasmic Reticulum (RER). RER is the site for protein synthesis.

Newly formed protein undergoes modification, one such modification is the addition of carbohydrate side chains to form glycoprotein. The protein then moves to the Golgi for modification.

Juli2301 [7.4K]

Answer:

125

Explanation:

The correct option would be 125.

<em>The carrying capacity of a particular environment generally refers to the maximum number of individuals of a particular species that the environment can support at a particular time based on the resources it has. Hence, the maximum population of a species will normally oscillate around the carrying capacity of the environment where it is found. </em>

In the case of the elephants in the illustration, the maximum population recorded was 125. The population decreased from this value at some point only to increased back to it later.

<u>Hence, the carrying capacity for the elephant is 125.</u>
