Answer: Polygenic means that most traits are controlled by an additive effect of two or more genes on a single phenotype.
Explanation: Polygenic inheritance or quantitative characters are those that vary in the population along a continuum. For example, height, skin color, etc.
Often, penetrance, pleiotropy, epistasis, expressivity and environmental factors are involved in producing a continuous distribution of phenotypes.
Traits such as height that show a continuous range of variation and do not behave in a single Mendelian fashion are known as quantitative or complex traits.
3 and 4 are correct. A compound is a collection of two or more molecules, whereas a molecule is a collection of two or more atoms. 1 is not true because its talking about two atoms together which is a molecule. 2 is not true because it is still talking about two atoms which is still a molecule. 3 is true because molecule are subunits of compounds. 4 is true because elements and atoms are the same thing, and two or more atoms is a molecule.

Answer:
There's more carbon dioxide in the winter and a bit less in the summer. That's the collective breathing of all the plants in the Northern Hemisphere. "Plants are accumulating carbon in the spring and summer when they're active, and they're releasing carbon back to the air in the fall and winter," Graven explains.
Explanation:
Hope it helps.
Answer:
The correct answer is - sensory neurons → inter-neurons → motor neurons.
Explanation:
The nerve system receives a signal from the external change or stimuli and transmitted it to the spinal cord and brain. The transmission of the signals or information is carried by three different types of nerve cells: sensory neurons, interneurons, and motor neurons.
Sensory neurons receive the signal from the external stimuli and converting it to the electrical impulses. Interneurons are the associative neurons that establish the connection between sensory neurons and motor neurons. Motor neurons are the efferent nerves that carry the signal from interneurons and brainstem or spinal cord and transmit to the muscles.
Thus, the correct answer is - sensory neurons → inter-neurons → motor neurons.
