Answer;
-These are positive impacts of dams to the society.
Explanation;
-Dams are important because they provide water for domestic, industry and irrigation purposes. Dams often also provide hydroelectric power production and river navigation.
-Other positive impacts include; dam wall itself blocks fish migrations, which in some cases and with some species completely separate spawning habitats from rearing habitats. It also traps sediments, which are critical for maintaining physical processes and habitats downstream of the dam.
B) Chlorophyll molecules are the largest of the all pigment molecules.
C) Chlorophyll reproduces faster than the other pigments.
D) Green is the color of the spectrum most easily seen by humans.
If yellow, red, and orange pigments exist in the leaves of trees. The leaves appear green except for the autumn because the chlorophyll is the most abundant of all the pigments present. Thus, the correct option is A.
Chlorophyll is a pigment which is present in all the green plants and in a few other organisms such as algae. It is required for the process of photosynthesis, by which light energy is converted into chemical energy in the plants. The chlorophyll pigment is responsible for the green coloration in plants.
However in the autumn, because of changes in the length of daylight and temperature, the leaves stop the food-making process. The chlorophyll pigment breaks down, the green color disappears from the leaf, and yellow to orange colors become visible in the leaves and give the leaves part of their fall splendor.
Therefore, the correct option is A.

Proteins and complex carbohydrates are part of the four major macromolecular groups and play crucial roles in our body functions and energy provision. They are essential in our diet, assisting in maintaining connective tissue, aiding blood clotting, and providing energy for our bodies.
Proteins and complex carbohydrates are both part of the four major macromolecular groups, which also involve lipids and nucleic acids. These macromolecules are vital to the human diet, providing fuel for the body, and undergo digestion and energy production processes. Carbohydrates can be both complex, like starch and glycogen or simple sugars like glucose and fructose. These sugars are key contributions to ATP production in cells, and glucose specifically, is controlled by a variety of endocrine mechanisms to regulate its presence in the bloodstream. The excess glucose is stored as glycogen in the liver and skeletal muscles, or instead transformed into fat in adipocytes.
Proteins along with carbohydrates are also essential in the maintenance of connective tissue and assisting in blood clotting. This prominence of these macromolecules in the diet is why athletes often 'carb-load' before engaging in major competitions, allowing their bodies to possess enough energy to compete at such high levels. Foods like grains, fruits, and vegetables are all natural carbohydrate sources, providing us with the glucose our bodies require. Therefore, proteins and complex carbohydrates showcase inherent essentiality within the human diet, playing significant roles in body function and providing necessary energy for activities.
