Answer:
A. Left-handed people usually exhibit a wider frontal, parietal, and occipital lobe on the left compared to the same lobes on the right.
D. Imagination, insight, and artistic skill are usually specialties of the right hemisphere.
E. Lateralization develops with age and is not already developed at birth.
Explanation:
<h2>The Forearm</h2>
Explanation:
The proximal end of the radius illustrates the relationship of form and function. The cup-like surface of the radial head articulates with the rounded shape of the capitulum. This forms a joint that allows for movement of elbows and forearms.
Radius and ulna are the two bones of the forearm. Their proximal ends articulate and fit into the cup like end of the humerus. This forms a synovial joint called the elbow joint. The movement of this joint allows the forearms to supinate and pronate.

On a global scale, energy flows through ecosystems whereas chemical elements are recycle in ecosystems. So the answer is the third option.
Energy flows through the ecosystem. Most energy comes from sunlight and it is transformed into chemical energy by autotrophs. When they are consumed by heterotrophs the energy is passed on, until it dissipates as heat.

Chemical elements like carbon and nitrogen, on the other hand, are cycled between biotic and abiotic factors in an ecosystem. This is not possible for energy. These chemical elements come from abiotic factors like the air, light and soil. They are incorporated in the biomass of the photosynthetic organisms and are consumed by other organisms. They are changed back into their inorganic form when the organism dies and are broken down by decomposers and the cycle goes on. So they are constantly being recycled.
In summary, energy needs a continuous source to be able to maintain and sustain the energy flow in the ecosystem. Chemical elements, on the other hand, are just recycled through processes between abiotic factors and biotic factors. </span>
Answer:
D. Plasmids are nucleic acids which can pass on traits
Explanation:
A Nucleic acid is one of the four biomolecule polymers in living systems. It is made up of monomeric units called Nucleotides. RNA and DNA are the two nucleic acids in existence and they function in storage and expression of genetic information.
According to the question, a colony of bacteria that can break plastics were mixed with the colony that can't break plastics. The two different colonies engage plamids, which conferred the ability to break plastics to some of the colonies that previously couldn't. This tells us that the ability to break plastics in the certain bacteria colony is GENETIC.
If the trait is genetic, the plasmid must be a nucleic acid because of the ability to genetically pass on traits. Note that, a plasmid is an extra-chromosomal DNA (nucleic acid) capable of replicating on its own. Hence, plasmids are nucleic acids which can pass on traits.
