Answer:
slightly positive and slightly negative charges of polar covalent molecules, such as water.
Answer:
Activated
Explanation:
In the presence of lactose, and in the absence of glucose, lactose will bind to a protein called a "repressor," deactivating it. Through this, RNA polymerase has a free way to synthesize the mRNA that will give enzymes for lactose degradation.
They are cooler and drier than tropical rain forests. Abiotic factors, or nonliving factors, of a temperate rain forest include temperature, water, cloud cover, soil and light. These abiotic factors interact with biotic, or living factors, to form the rain forest's unique ecosystem.
Answer:
C. Mutation.
Explanation:
The mutation is the source of all genetic variation. There are two types of mutations. One is the natural mutation, and another is the artificial mutation. The natural mutation occurs due to the environmental cause, and humans using various mutagens do artificial mutations.
These two types of mutations always bring variation in any organism. This variation can be positive or can be negative too. Natural mutation is not possible to control so that anything can happen. Either positive or negative changes can occur. But in the case of artificial mutation, in 90% cases, positive results come in genetic variation.
