Answer:
Convection
Explanation:
The process where molten magma rises and sinks due to the temperature difference is known as CONVECTION.
This occurs when the hot magma moves upward and is cooled and moves downward again to be heated due to temperature difference, and similarly when cold magma moves upward and is heated and moves downward again to be cooled due to temperature difference.
Hence, in this case, the correct answer is CONVECTION
<span>Proteins that are involved in the packaging of eukaryotic chromosome into "beads" called nucleosome are histones.</span>
A nucleosome is a segment of DNA wound in sequence around eight proteins called histones. Together the DNA and the histones form "beads"
A nucleosome is the basic unit of DNA packaging in eukaryotic cells.
Answer: Option A) receiving; sending
Explanation:
The neuron is made up of many parts, they include:
- dendrites, which are branched and helps in receiving impulses from the adjacent neuron
- axon, a long and extended portion of the neuron that the transmission of impulses along its length away from the cell body.
- synapse etc
Thus, dendrites of neurons is involved in receiving impulses into the neuron, while axons is involved in sending impulses away from the neurons
