ANSWER:
C. Red blood cell, heart tissue, circulatory system
BECAUSE:
Red bloods cells make up heart tissues and heart tissues make up the organs in the circulatory system.
Red bloods cells are therefore simpler than heart tissues and heart tissues simpler than the circulatory system.
It can’t be A because blood is simpler than the circulatory system
It can’t be B because nerves and the brain are simpler than the nervous system
It can’t be D because bone is simpler than the skeletal system
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products. In a chemical reaction, only the atoms present in the reactants can end up in the products.
Answer:
Option (4).
Explanation:
Phosphatidylinositol4,5-bisphosphate (PIP2) is the phospholipid present in plasma membrane. This lipid is important for the cell communication and cell signalling process.
The PIP2 can cleave and give two main products are DAG (diacylglycerol) and IP3 ( inositol 1,4,5-trisphosphate). These two molecules are important for the cell signalling.
Thus, the correct answer is option (4).
Answer:
The main role of inorganic compound in microbes is the generation of energy in the form of Adenine tri phosphate (ATP) that is required for the growth and reproduction of microorganisms.
Explanation:
Inorganic compound are those in which carbon atom is absent. Many microorganisms especially bacteria, use inorganic compound such as ammonia, hydrogen, ferrous and sulfur etc for the production of energy that is used in different processes and activities such as reproduction and growth.
Answer:
Chloroplasts and vacuole
Explanation:
Plants have a central vacuole that only plants have as well as chloroplast.
