Answer:
D
Explanation:
The neural pathway regulates the action reflex. At times sensory neurons synapse occur in the spinal cord rather than the brain, this allows for a quicker reflex action. Synapses in the spinal cord activate spinal motor neurons without delay, which is likely the case if the signals go to the brain, the brain doe however receive the sensory input during the reflex action.
Answer:
Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells
Explanation:
Totipotent (or Omnipotent) Stem Cells.
Pluripotent Stem Cells.
Multipotent Stem Cells.
Oligopotent Stem Cells.
Unipotent Stem Cells.

mendel and darwin!! hope this helps!!
Explanation:
Answer: Mendel would have concluded that one pair of factors (genes) is responsible for two different characters in plants.
Explanation:
The 9:3:3:1 ratio observed by Mendel helped him to form his <em>Law of Independent Assortment </em>which states that the inheritance of one pair of factors (genes) is independent of the inheritance of the other pair.
Also from his previous studies, he obtained a 3:1 ratio for a single gene expression, flower color, which enabled to form <em> the Law of Segregation</em>, which states individuals possess two alleles and a parent passes only one allele to his/her offspring.
However, if he had observed a 3:1 ratio for two traits, he would have concluded that inheritance of characters occurs in pairs i.e., that a pair of alleles is responsible for two different characters in plants.
