Answer:
The two hydrogen atoms and one oxygen atom within water molecules (H2O) form polar covalent bonds. ... As a result of water's polarity, each water molecule attracts other water molecules because of the opposite charges between them, forming hydrogen bonds
answer:
: D.finding fossils in the same area that are in layers closer to the surface.
Relative dating refers to the age estimation method in which past events are determined, to compare the age of object, organism, strata or rock with the age of other similar entity. This method gives an approximate or estimated age, it does not provide absolute age.
The older fossils are found in deeper layers of the strata as compared to younger fossils. This represents the geological time and life span of primitive or preexisting organisms. Therefore, according to the given situation, finding fossils in the same area that are in layers closer to the surface is the best conclusion
<span>Ian Waterman was able to sense pain and temperature because his
spinothalamic pathway was intact, but could not feel touch and limb position because of damage to his
lemniscus pathway. </span>
The lateral spinothalamic tract is a sensory pathway which carries sensory information like pain and temperature to the brain, across the thalamus. Free nerve endings which are located in the peripheral tissues are sensitive to cell damage. Those are primary neurons and they pass the sensory signal. Primary neurons synapse with secondary which are located in the spinal cord (white matter). These secondary neurons will ascend through the brainstem, medulla oblongata, pons and midbrain, until synapsing in the ventroposteriorlateral (VPL) nucleus of the thalamus. From the thalamus, the information is sent to cortex (somatosensory cortex).
Posterior column-medial lemniscus pathway is ascending spinal tract, carrying sensory information to the brain (sensory pathway). It conducts localized sensations of fine touch, vibration and proprioception (position sense) from the skin and extremities (muscles) to the central nervous system (cerebral cortex).
Answer:
COMMENSALISM
Explanation:
The interaction of organisms with one another in an ecosystem is called SYMBIOSIS, if it involves two organisms of same or different species. One type of symbiotic relationship is COMMENSALISM, which is a relationship in which one organism benefits while the other neither benefits or gets harmed.
This is the case of the burdock weed and its association with cows, deers or people. The burdock weed benefits from the relationship by getting Its seeds that attaches to the cow's, deer's or human's skin via its hooked-tip burrs, transported to varying locations. Thus, helping to spread the plant. The cow, deer, or human does not benefit fron this relationship neither is it harmed.
When a cell divides into two cells going through 4 phases.
