Answer,
Ribosomes
Explanation,
Ribosomes are cell organelles which help to produce proteins.It contains RNA and DNA strands which help in formation of new proteins.The synthesis of proteins takes place in two stages transcription and translation.Transcription takes the information encoded to the DNA and encodes it into mRNA which heads to the nucleus inthe cytoplasm.Translation mRNA works with a ribosome and tRNA to synthesize proteins.
The ecological pyramid is smaller at the top due to the lower amount of species to fit into the category (diversity is decreased, and the higher, the more suppressed the energy is in the animals/species).
True rib : the first seven ribs attach to the sternum (the breast bone) in the front and are known as true ribs (or sternal ribs)
False ribs: the lower five ribs do not directly connect to the sternum and are known as false ribs
Floating ribs :The floating ribs are less stable and risk breaking because they have only one attachment
Dorsally to the vertebrae and have very thin bone tissue locked in muscle as they extend
Laterally.
Answer:
B. A sperm cell
Explanation:
Meiosis creates gametes/sex cells, such as the sperm and egg.
So, sperm cells are formed by meiosis.
Meiosis doesn't create fertilized eggs, it instead creates normal egg cells.
Meiosis also doesn't create heart and bacterial cells because those are made in mitosis.
So, B is the correct answer.
