Answer:
True
Explanation:
In cell biology, the centrosome is the main microtubule organizing center that is important for cell division. The major function of the centrosome is to maintain the chromosome number during cell division.
Other function of centrosome during cell division include initiate the changes in cell membrane shape through phagocytosis and organize microtubules in mitosis that ensures the distribution of the centrosomes into daughter cell.
Hence, the given statement is true.
Answer: nucleolus
Explanation: Ribosomes are manufactured in the nucleolus. Ribosomes are the sites where protein synthesis takes place. Ribosomes are usually made up of two subunits: one large subunit and one small subunit. Ribosomes are manufactured and assembled in the nucleolus. Ribosomal proteins combines with four ribosomal RNA strands in the nucleolus to form two ribosomal subunits: one small subunit and one large subunit that make up the complete ribosome
Answer:
Carbs - provide your body with energy.
Lipids - serve as structural components of cell membrane, function as energy storehouses, and function as important signaling molecules.
Protein - helps with growth and maintenance of tissues, enzymes that cause biochemical reactions in and out of your cells, some proteins are hormones so it acts as a messenger the aid communication between your cells, tissues, and organs. And many other thing that are a google search away.
Nucleic Acids - hold storage and expression of genetic information
i think the correct answer is B considering that the channels are not always open for the protons to freely diffuse through the inner membrane.
