Answer:
b. pieces of DNA is the correct answer.
Explanation:
A gene is a piece of DNA and it is present in the nucleus of all cell's
The function of the gene is to codes for a specific type of protein.
Genes convey the message that determines our characteristics
Genes are called as a functional unit of genetics.
The mantle is a layer inside a planetary bodybounded below by a core and above by a crust. Mantles are either made of rock or ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone differentiation by density. The mantle is bounded on the bottom by the planetary core and on top by the crust. In addition to the Earth, the other terrestrial planets, a number of asteroids, and moonshave mantles.
Answer:
Ribosome
Explanation:
Ribosomes are mainly made up of ribosomal RNA and ribosomal proteins. Each has two subunits (30S and 60S or prokaryotes) and 40S and 60S in eukaryotes. The smaller unit usually reads the mRNA -with the message from the nucleus -on how to ‘manufacture’ the proteins. The larger subunit actually does the translation by bringing in t_RNAs that carry specific amino acids and then forming peptide bonds between amino acids and ultimately forming polypeptide chains.
- Respiration is the process in which animals and plants take oxygen from the atmosphere.
-Excretion is the process in which living beings get rid of waste products.
-Locomotion involves any form of movement made by living beings.
-Photosynthesis is the process in which plants use water, sunlight, and carbon dioxide to create oxygen and energy.
The correct answer is Photosynthesis
Answer:C
Explanation:
The arteries are not a cell bc that is too simple a tissue is also too simple its not a system bc arteries are not a lot of organs working together so its C
