Huntington's Disease (HD) is a rare and fatal neurodegenerative disorder that results in hyperkinesia. One of the issues that occurs as a result of Huntington's is deficits in axonal transport mutations in the huntingtin (Htt) gene result in the loss of anterograde transport of organelles such as mitochondria. Among their many functions, mitochondria are thought to sequester Ca ions. 2 You are working with an animal model of HD. You are recording postsynaptic responses of neurons receiving synaptic inputs from presynaptic neurons in either normal tissue or HD tissue. You note that the postsynaptic responses occur 3-5x more often in the HD tissue than that of normal tissue. Propose a mechanism wherein the Ht mutation could produce this increase in the responses of the HD neurons.

prism b but im not for sure

blue stars have the highest surface temp

stellar distances are usually expressed in light-years

the measure of a star's brightness is called magnitude

hope this !

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
