D. sexual selection
D. Mutations
<span>These are all component of evolution in the promotion of biodiversity. How an organism evolves due to mutation, selection and adaptation. </span>
<span>Biodiversity depends on a species' ability to reproduce itself. If a species cannot reproduce then it will die out. This depends on the climatic conditions of the region. If there is a natural disaster for example, it will affect a species' ability to reproduce. This reduces the number of diverse species on earth. Biodiversity is the recognised variety of different types of life found on the earth. It also measures the variety of number and variety of plants, animals and other organisms found in different ecosystems.<span> </span></span>
Answer: The correct answer is -
D) A ---> B + C + energy.
Explanation:
Catabolic reactions can be described as one of the two types of metabolic reaction (other being anabolic) which occur within cell when complex organic molecules are broken down to form simpler, smaller molecules.
For example - Respiration, which involves glucose breakdown in order to form carbon dioxide and water. Generally they are type of hydrolysis reactions, which include water to break bonds present in complex molecules.
Large amount of energy is also released during these reactions.
Thus, option D) shows catabolic reaction.
Standard of living refers to the quality, and quantity, of goods and services made available to an individual for his/her consumption. This definition is a general one and is easily understood.
To improve one's standard of living, in accordance with this definition, one needs to be provided with a better quality goods & services , such as advanced electronics and gadgets, or quantity, such as producing more self-care product for consumption.
So how does this conflict with his/her environmental concerns? In order to improve standard of living, there is a few trade offs. To produce more quantity of goods & services, more resources have to be used. This might lead to excessive usage, wastage & depletion of natural resources. For example, to provide more fuel to the society, companies have to extract more & more of fossil fuel. Sustainable usage of natural resources might be a concern, since some types of resources are unrenewable e. g oil & gas.
Production of higher quality products requires advanced state of technology. In the meantime, the use of some technologies aren't exactly environmental friendly i. e it may create pollution. For example, decades ago, manufacturing shirts using traditional methods might not yield consistent results thus the invention of machine helps with increasing the quality, however, results in noise and air pollution. Another example, using air-conditioning instead of hand fan is more effective in coping with hot weather, but greenhouse gas is emitted.
This shows the conflict between environmental concern and the desire to improve standard of living in general.
Hope this helps!
