Heritable traits are known to be passed from one generation to the next via DNA, a molecule that encodes genetic information.Organisms inherit genetic material from their parents in the form of homologous chromosomes, containing a unique combination of DNA sequences that code for genes.
Answer:
Traits are passed down from one generation to another because of DNA.
Explanation:
Genetic inheritance occurs due to genetic material, in the form of DNA, being passed from parents to their offspring. When organisms reproduce, all the information for growth, survival, and reproduction for the next generation is found in the DNA passed down from the parent generation.

A. through impulses
B. through motor neurons
C. through interneurons
D. through sensory neurons
Answer:
The place where the axon of one neuron meets the dendrite of another is called a synapse. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite. The binding allows the nerve impulse to travel through the receiving neuron.

Which diagram correctly portrays the direction of the prevailing winds in each latitude band? (look at the pictures)
A.
E.
B.
C.
D.
Option C and E are the diagram which correctly portrays the direction of the prevailing winds in each latitude band
what is latitude?Latitude and longitude are two most important terms which are the coordinates that, together, tells exactly location of an object on the surface of the Earth.
Latitude tells the position of the object or anything between the North Pole and the South Pole where equator is zero degrees, the North Pole is 90 degrees North, and the South Pole is 90 degrees .
Parallels called as latitude lines which run across the Earth from east to west at a constant latitude, for example would be the equator, which is at zero degrees of latitude
Latitude is major indicator of navigation because the path of the sun is different depending on the object's latitude, so it varies based on the time of year.
