A, B and C are the events that will cause an ecological disturbance.

Rationale:

A. Introduction of a new species: When a new specie is introduced, it increases the competition in ecosystem with the native species for food, water, space and shelter. This affects the reproductive success of the native species and thus the dynamics of ecosystem.

B. Climate change: Climate change is different from a simple change of weather. The best example would be of Antarctica where the ice is melting fast due to the global warming. The native species find it harder to adapt to the warm temperatures.

C. Late spring snowstorm: Spring is the season where the plants grow and animals shed their fur. When snowstorms occur in this season they harm these plants and animals that live there.

What would need to happen for copper not to not exsist anymore.

Electricity could be discovered using batteries based on zinc or lead, but without copper wiring it would remain little more than a scientific curiosity. Electric motors and generators require large amount of wiring, so they are impossible to build on large scale in this world

If a linear piece of dna has three sites for a particular restriction enzyme, into how many fragments will that restriction enzy

Kruka [31]

If a linear piece of DNA has three sites for a particular restriction enzyme, it will be cut into 4 fragments. If the DNA is circular, the number of obtained fragments will be N for N recognition sequences for the specified restriction enzymes however if the DNA is linear, the number of obtained fragments will be (N+1).

A bacterial protein called the restriction enzyme cleaves DNA at specific locations. The recognition sequences, or short and distinct nucleotide sequences, are recognized by restriction enzymes in DNA. When a DNA sequence is recognized by the restriction enzyme, it hydrolyzes the bond between neighboring nucleotides and cleaves the DNA molecule.

The restriction enzymes guard against bacteriophages on the living bacteria. They identify the bacteriophage and cleave at its restriction sites, destroying its DNA.

The use of restriction enzymes in genetic engineering is crucial. In order to introduce foreign DNA for gene-editing purposes, restriction enzymes cut DNA at a specified location, which makes them a crucial tool.

Which region of the human brain best distinguishes us from other animals?

MAVERICK [17]

Out of the following given choices; a. reticular formation b. cerebral cortex * c. limbic system d. hypothalamus

The answer is B. This region of the brain is responsible for cognition, consciousness, thought, and memory. It is these qualities, especially self-awareness and cognition, that distinguishes humans from other animals. It enables humans to reason, plan and have great social intelligence.
