Cell-tissue-organ-organ system-organism
Answer:
This question is incomplete as it lacks options, however, it will be answered BROADLY so the it can be understood enough to select the correct answer.
Please find the explanation below
Explanation:
Cells perform different functions and look differently because of the process of CELL DIFFERENTIATION. All cells arise from a single stem cell, which then gradually differentiates into different types of cells with different functions, as they divide.
At the molecular level, these different types of cells contain the same DNA sequence as rightly stated in the question. However, they look and perform differently because some of the genes are turned on while the others are turned off via the process of GENE EXPRESSION.
Therefore, a blood cell and skin cell possess exactly the same DNA sequence but look different and perform different functions because of CELL DIFFERENTIATION in which some genes on the DNA sequence are expressed and others are repressed. For example, in the blood cell; the genes coding for certain proteins found in blood are expressed while every other gene is silenced or inhibited. This allows those cells to perform only blood-related functions.
Because less animals means less energy that can be used.
Answer:
A. It contributes to global warming
Explanation:
- Solar power is the power of the future and is an essential nonrenewable source of energy for man. Solar power is driven by the incoming solar energy in the form of solar rays.
- Solar power is eco-friendly and doe not cause any harm can be sued in the summer season and has ample scope for greenhouse gases.
- As per the statement, the solar power should be used as the main energy source in U.S can be contradicted by saying it contributes to global warming.
The group of chemical processes in organisms that maintain life is known as metabolism. The three primary functions of metabolism are: converting the energy in food into energy that can be used to power cellular functions.
It is convenient to divide metabolism into two groups: Molecules are broken down during catabolism to provide energy. All of the substances that the cells require are synthesised during anabolism. Metabolic processes include the chemical reactions that keep you alive. One example of metabolism is the rate at which you burn fat and consume calories. the constant anabolic and catabolic chemical and physical processes that occur in living things and their cells. Specific areas of the cell host metabolic events. The cytoplasm is where amino acid degradation and some phases of glycolysis, fatty acid synthesis, and glycogen synthesis take place. Within mitochondria, certain metabolic pathways are located at particular points.
