Answer:
The correct answer is - option B.
Explanation:
The diagram or pyramid for the energy flow of an ecosystem represents the flow of energy from one end to the other end according to the food chain. It starts with the ultimate energy source the sun which is used by the producers to produce energy and this is the trophic level that carries the highest energy.
In the food chain, when primary consumers eat the producers they get 10% of the total energy producers carries due to loss of energy and 10% energy of primary consumer have transferred to secondary consumer and so on.
Answer:
Glycocalyx
Explanation:
Most of the eukaryotic cells have a coating outside their cell membrane. This coating is called the glycocalyx. It consists of glycoproteins and glycolipids. The sugar parts of these compounds are in contact with the underlying plasma membrane. The function of the glycocalyx is to protect the cell. Certain specific molecules of the glycocalyx are involved in the recognition of cells so that they can recognize one another to make contact.
Answer:
B) Messenger RNA
Explanation:
Messenger RNA [mRNA] molecules carry the coding sequences for protein synthesis and are called transcripts.Ribosomal RNA [rRNA] molecules form the core of a cell's ribosomes [the structures in which protein synthesis takes place] and transfer RNA [mRNA] molecules carry amino acids to the ribosomes during protein
True. it starts off simple then you move into details
