a central vacuole is a cellular organelle found in plant cells
Answer:
The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.

Answer:
9. Bees play a very important role in relation to agricultural production. Indeed beekeeping is a vital part of our agricultural system. Apart from crop plants which are highly dependant on bees, the presence of honey bees also improves the quality and quantity of crops in general.
10. Use insect repellent. Permethrin-impregnated clothing and insect repellent have not been proved to be particularly effective against tsetse flies, but they will prevent other insect bites that can cause illness. The World Health Organization has targeted West African trypanosomiasis for elimination as a public health problem by 2020.
Explanation:
Answer:
1. transcription of mRNA from DNA
2. small ribosomal subunit binds to mRNA
3.initiation complex formed with addition of large ribosomal subunit
4.codon recognition (non-initiating site)
5.peptide bond formation
6.translocation
7. ribosome reads a stop codon
8.polypeptide chain is released from the P site
9. ribosomal subunits dissociate
Explanation:
The translation is a process which translates the nitrogenous bases or codons in the proteins.
The process of translation requires the mRNA, tRNA and ribosome and proceeds in three stages: the initiation, elongation and the termination.
The process begins with the binding of the small subunit of the ribosome to the mRNA. The charged tRNA with a first amino acid called methionine binds the mRNA and scans the mRNA until it finds the start codon.
After it finds the start codon, the large subunit complex binds the mRNA and form initiation complex. After this, the amino acid enters the P-site of the ribosome where elongation of peptide takes place.
The peptide then exits from the E-site and the ribosome dissociates.
