Question

Please answer 1-5

Voluntary muscles are composed of which type of muscle? Select one: O a smooth O b. cardiac O c. skeletal O d. none of the above Cells make energy in the form of which powers cellular function. Select one: Оа. АТР b. amino acids O c. hormones O d. neurotransmitters Organisms grow due to and are capable of reproducing through the production of gametes in Select one a transcription, translation b. translation, transcription c. meiosis, mitosis d. mitosis meiosis

Answer 1

1. Skeltal muscle is the right choice. They are striated muscles with syncitium. Cardiac muscles are found assosciated with heart and smooth muscles are seen on abdomen, urogenital tract etc. In skeltal muscles collagen can be seen. Skeltal muscle supports voluntary movements.

2. ATP. Adenosine trinucleotide phosphate which produced in mitochondria helps cells regulatory function. The are generated in response to aerobic respiration, electron transport chain, macromolecule metabolism etc. ATP is generally nitrogen base which combined with phosphate group. The cleavage of phosphate bond gives energy. Aminoacids are protein monomers. Hormones are intracellular siginals.

3. Mitosis is the process of cell division that helps in growth. It is equational division that maintain nucleocytoplasmic ratio. These type of division enable cell repair, replacing of damaged cells etc. Meosis is reduction division which occurs in sex cells. It is the meosis ensure variability among individuals. Translation and transcription are gene regulation process.

4. The sacs are called alveoli. It is through alveoli oxygen diffusion takes place into blood and co2 exchange occurs. Alveoli are seen at terminals of bronchi tubes. They are microscopic and millions in number. Angina and aorta are assosciated to heart.

5. Mitochondria is the structure inclusive to eukaryotes . Prokaryotes lack mitochondria and regulate ATP production by cell surface. All other structures can be seen in both. Ribosomes are 70 s in prokaryotes and 80s in eukaryotes.
