Answer:
Characteristics of polar molecule
- they should have opposite charge
- they should have same dipole moment value
- they should have electronegativity different
Explanation:
Polar molecule is characterized by an uneven distribution of the electrons that form the covalent bonds between each atoms in the molecule
Polar molecules has a net dipole as a result of opposing charges from polar bonds, since water has slightly positively charged side and a slightly negatively charged side. This makes it a polar molecule
The third one,
Autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy. Plants also use glucose to make cellulose, a substance they use to grow and build cell walls.
Answer:
availability of resources.
Explanation:
Availability of resources is abiotic factor which is responsible for the decrease in population in 1990 because when the population reaches its carrying capacity so the organisms compete with each other and due to limited resources such as food etc the decrease occurs in population. Infection is also occurs when there is high population due to which death occurs and population of organism decreases.
