Answer: So whats your question?
Answer:
A
Explanation:
Passive transport does not require energy. The substances follow the concentration gradient, meaning they go from high to low. Active transport goes against the concentration gradient. Substances go from low to high, so it requires energy.
Answer:
The third sentence is not correct. The correct statement would be as follows:
because the contents of the lumen of ER (or any other compartment) in the secretory or endocytic pathways never mix with the cytosol, Proteins that enter these pathways is never imported again.
Explanation:
During mitosis, specifically during prophase, when the nuclear envelope breaks down, or in other words, retracts from the chromatin, its content that is the membrane protein intermix with the ER membrane protein. However its content will always remain separated from that of the cytosol because of the presence of an intact membrane.
Answer:
The options are:
A. Gravel
B. Sand
C. Silt
D. Clay
E. Mud
The answer is A. Gravel
Explanation:
Meiofauna are small benthic invertebrates which live in aquatic habitat. They are suited for both marine and fresh water environments.
Gravel aren’t tightly packed together in large quantities when compared with the other options such as sand, silt, clay, mud. This makes it possible for more aeration and the presence of more oxygen at the soft-bottomed intertidal community.
