Answer:
The correct option is B. Prokaryotic
Explanation:
A prokaryotic cell can be defined as a cell which is unicellular and does not have any membrane-bound organelles present in it. Scientists claim that the earliest form of life was in the form of prokaryotic cells. The bacteria and archaea bacteria come under the category of prokaryotes.
The prokaryotic cell lack a nucleus. It's DNA material is present in a region called the nucleoid inside the cytoplasm of the cell.
Answer:
The correct answer is B. clavicle articulates with the manubrium of the sternum.
Explanation:
The clavicle is an anterior bone whose sternal end articulates with the manubrium of the sternum at the sternoclavicular joint. The sternal end is also anchored to the first rib by the costoclavicular ligament. The medial end, also known as the sternal end of the clavicle, has a triangular shape and articulates with the manubrium portion of the sternum. This forms the sternoclavicular joint, which is the only bony articulation between the pectoral girdle of the upper limb and the axial skeleton.
Answer:
A cell is defined as the structural and functional unit of an organism.
The average size of the prokaryotic cell lies between 0.1 to 10 micrometers whereas the average size of the eukaryotic cell is approximately 25 micrometers.
Four things are found in all the cells: genetic material (either DNA or RNA), cell membrane, cytoplasm, and the ribosome.
All the living cells grow and reproduce (sexually or asexually) and have the ability to respond to stimuli.
Thus, characteristics of a cell may include: cell grows and reproduces, responds to stimuli, contains DNA or RNA, not both , and contains a cell membrane.
The answer is; warming of ocean water in the east of the Pacific Ocean close to the western coasts of South America.
The warming of the oceanic waters causes a current that pushes the warm waters eastwards of the Pacific Ocean at the equator. This counters and overpowers the prevailing trade winds that blow westwards. The currents bring in storms on the West coast of South America as the currents exchange heat with the atmosphere .
Answer: Yes.
Explanation:
DNP and cyanide are both cellular respiration inhibitor.
Cyanide is a neurotoxin that can prevent cellular respiration by it's inactivation activity on mitochondria enzymes called cytochrome oxidase.
DNP (2,4-Dinitrophenol is a chemical that inhibit cellular respiration. It help to shuttle proton across cell membranes of living cells by spreading the proton along along the mitochondria and collapsing the force that produced energy for the cell activities.
