Answer:
Lipids are the biological molecules which are used as long-term energy storage. Lipids can be described as biological molecules that are not soluble in water but are soluble in non-polar solvents.
Triglycerides are a type of lipids which are present in the adipose tissue. These molecules serve as major long- term energy storage molecules both in plants as well as in animals.
Carbohydrates serve as quickest energy molecules whereas lipids serve as molecules which can store energy for longer periods.
Answer:
3) passive transport
Explanation:
Passive transport is a type of cellular transport that does not require the use of energy to move substances (i.e., ions and molecules) across biological membranes. Passive transport uses concentration gradients to move substances across cell membranes, thereby transporting them from regions of high concentration to regions of low concentration. Passive transport can be divided into 1-osmosis (i.e., movement of solvents), 2-diffusion (i.e., movement of solutes), and 3-facilitated diffusion (i.e., movement of molecules with help of protein channels or carriers), and 4-filtration (i.e., movement of water by using a pressure gradient).
Generalist species are adapt to live in a wider range of environment conditions. Specialist species are adapt to live in a narrow range of environment conditions. Thus, specialists are in a greater danger if some of the conditions in the environment change. For example, species A and B live in a river with an average temperature of 17°C. Species A is the generalist species and it can survive water temperature of 5-35°C. Species B is the specialist species and can survive water temperature of 15-20°C. If the temperature of the river decrease to 10°C, specialist species B will not survive but generalist species a will survive.
Answer:
Biome, a large area of ecological importance where plants and animals or flora and fauna co-exist in the same environment where they have common characteristics.
Biomes are highly sensitive to climatic changes.
They are characterized by non-living or abiotic factors like relief, climate, soil, temperature and vegetation.
The main five types of biomes are- a. The Desert Biomes, b. The Aquatic Biomes, c. The Forest Biomes, d. The Grassland Biomes and e. The Tundra Biomes.
