The one dated back to about 1 million years would most likely have more similarities to the modern day horse, so the answer should be the rock fossil which is 1million years old.
The large intestines removes water from undigested food.
Answer:
<em>To get energy from stored glycogen (in the liver), the body must first convert the glycogen into </em><u><em>ATP.
</em></u>
<em>(ATP stands for Adenosine Triphosphate . This is the energy currency of most cellular processes .)</em>

The answer would be true
The objective of vaccination is to elicit the primary immune response by introducing pathogen antigens. This antigen can be a whole weakened pathogen or just part of pathogen proteins.
The antigen will activate the primary immune response cascade that <span>will </span>activate of B-cells and T-cells from the secondary immune response. This will makes secondary immune response ready when the real pathogen comes.
Answer: The action cytoskeleton structure is dynamic.
Explanation: Actin cytoskeleton is a dynamic structure necessary for cell and tissue organization, including the maintenance of epithelial barriers. The epithelial barriers are necessary to maintain barriers, the disruption of the epithelial barrier coincides with alterations of the actin cytoskeleton in several disease states. Primarily these disruptions affect the paracellular space, that is normally regulated by tight junctions. The actin cytoskeleton is a usual target of bacterial virulence factors. Bacteria secrete and inject toxins and effectors to hijack the host cell machinery, in order to manipulate the action cytoskeleton, which interferes with host-cell pathways and with a number of actin binding proteins.
