Answer:
The correct answer is - option B. it increases the amount of genetic variation in the species.
Explanation:
Meiosis is a type of cell division that takes place in sex cells or reproductive cells. There is crossing over takes place which is a process where the genetic exchange of chromosomes occurs between non-sister chromatids of homologous chromosomes.
The crossing over leads to the new genetic combinations of genetic material which result in the genetic variation in species. This variation plays a role in the natural selection and evolution of species.
A positive charge is created in the cell that travels down it does a nerve
impulse begin in a neuron. Thus, the correct option is A.
<h3>
How the neuron get stimulus?</h3>
When a neuron receives a chemical stimulation, a nerve impulse is formed. The electrical action potential of the nerve impulse passes along the axon membrane to the axon terminal. Neurotransmitters are released at the axon terminal, which transfer the nerve impulse to the next cell.
The resting potential of a neuron is the electrical differential across its membrane. The sodium-potassium pump, a transport protein, creates the resting potential. This protein generates a positive charge by moving a high number of sodium ions (Na+) outside the cell.

Answer:
The 5 impacts humans have on the environment in order from easiest to fix to hardest to fix is explained below in details.
Explanation:
Humans impact the physical surroundings in various forms: pollution, smoking fossil fuels, overpopulation, including deforestation. Developments like these have triggered climate modification, soil erosion, poor air quality, and impure water.
The Biggest Environmental Problems
- Biodiversity Decline.
- Plastic Pollution.
- Deforestation.
- Air Pollution.

Answer:
Predation
Explanation:
A relationship in which one species consumes and the other is killed is known ans predation.
For example;
Take the came of a tiger and a deer, in this case the tiger is the cunsumer or the predator while the deer is being killed and devoured
