Since homologous means same structure different functions, it shows that animals evolve to have the same structure as their ancestors but, have different uses to the part
When charged particles from the sun strike atoms in Earth's atmosphere, they causeelectrons in the atoms to move to a higher-energy state. When the electrons drop back to a lower energy state, they release a photon: light. This process creates the beautiful aurora, or northern lights
Answer:
A threshold level depolarization.
Explanation:
In a neuron, the action potential threshold is known as the point of depolarization where the neuron fires, when the neuron reaches a point, it will fire and if it does not reach the point of depolarization, it will not fire and it helps to transmit the information to another neuron.
A neuron transmits the information with the help of electric impulses which are sent through its axon. When a neuron in an inactive phase, more +ve charged ions recline outside the axon membrane. In the process of stimulation, the axon membrane admits more Na+ ions and providing the neuron more +ve charge.
Answer:
Having a standard system of measurments.
Explanation:
If they have one set of measurements used around the world, it is easier to communicate and work together.
have a nice day! :)
Answer:
phenotype
Explanation:
Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
