Answer:
Pinocytosis is the mechanism by which living cells consume liquid droplets. Endocytosis is the general mechanism by which cells ingest foreign substances and collect them in special membrane-bound vesicles within the cell. Pinocytosis is one form of endocytosis.
Answer:
The correct answer is D. The surface of the skin can be mapped into distinct regions, each served by a single spinal nerve: these regions are called dermatomes.
Explanation:
A dermatome is the area of skin innervated by a single spinal nerve and its spinal ganglion. The cutaneous nerves are those that reach the skin, picking up the sensitivity of the skin. Each cutaneous nerve is distributed in a certain area of skin, called a dermatome.
A pair of posterior or sensory roots and a pair of anterior or motor roots arise from each cord segment, joining laterally at the level of the intervertebral foramen to form a mixed spinal nerve. Each of these innervates a strip of skin called a dermatome, so the body surface can be considered a true mosaic of these.
In the extremities the arrangement of dermatomes is more complicated because of the embryological rotation of the limbs as they grow from the trunk.
The answer would be all of the above.
Answer:
The diagram represents the Law of Dominance
Explanation:
Any particular trait can be dominant or recessive in an individual who is heterozygous for it depending on their inheritance pattern from the parent genotype. Although the individual will be carrying the recessive allele in their genetic code too, it is only the dominant phenotype that is expressed. The dominant trait is represented by the capital letter whereas the recessive trait is represented by a small case letter.
In a survivable cold environment, an ectotherm is more likely to survive an extended period of food deprivation than would an equally sized endotherm because the ectotherm is using a little amount of its energy for temperature regulation.<span />
