Answer:
A. It decreases the activation energy needed to start the reaction.
Explanation:
Catalase is an enzyme found in the cells of organisms exposed to aerobic conditions. It is an enzyme that catalyses the breakdown or decomposition of hydrogen peroxide in the liver to water (H2O) and oxygen (O2).
Catalase, like every other enzyme, operates by binding to the substrate, which in this case is hydrogen peroxide. Catalase then REDUCES or LOWERS the ACTIVATION ENERGY needed to start the reaction.
Answer:
The correct answer will be option-
Hydrogen (atom) →water (molecule)→ liver (organ) →skin (cell) →elephant (organism) → wolf pack (population) → tropical rainforest (ecosystem) →planet Earth (Biosphere).
Explanation:
The biological level of organization is the arrangement of the matter from the smallest to the largest in the hierarchy.
The smallest unit of matter is the atom which forms the molecules. These molecules together form the organelles which aggregate and form the basic unit of life called cell. The cells aggregate-gate and perform the same functions to form tissues which together form the organs. These organs constitute the organ system which forms the organisms. The organism together forms the population which form the community. The community becomes a part of the ecosystem which forms the largest level called the biosphere.
On the basis of this, the given options are arranged.
Answer: A. True.
Explanation: A substance or material is hazardous if can be dangerous to a susceptible agent. This susceptible agent can be a human being, an animal, a plant, a fungi or any other living form, or an environment agents like water, soils, air etc. that can be contaminated with it and later could be dangerous for a living forms.
The answer is a pedigree chart.
<span>Pedigree charts are used to explain the occurrence of particular genes from one generation to the next. It gives enough information about family disease history. They are used in families to find out the probability of inheriting some disease. So, if Maria and Juanita are cousins and the genotypes of other members of their family are known, the pedigree chart could predict their genotypes. Still, it is not as precisely as DNA test.</span>
