Biology
1 answer:
Vikentia [17]3 years ago
6 0
  1. The environment needs to change in order to natural selection to occur.

Reason:

Because, Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

2. Population has some genetic variations.

Reason:

Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by:

mutation and random mating between organisms

3. Nature select organism with specific traits to survive and reproduce.

Reason:

According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

Ket [755]

Answer;

-Neurotransmitters.

One of the first key terms she memorizes is neurotransmitters because these are the chemicals via which neurons communicate with each other.

Explanation;

-Neurons communicate with each other via electrical events called 'action potentials' and chemical neurotransmitters. At the junction between two neurons (synapse), an action potential causes neuron A to release a chemical neurotransmitter.

-Neurons are connected to each other through synapses, sites where signals are transmitted in the form of chemical messengers.
