Answer:
A protein with its amino-terminus in the cytoplasm and its carboxy-terminus in the extracellular space. (Ans. A)
Explanation:
Integral membrane protein (IMP) is defined as a membrane protein molecule which is directly attached to the biological membrane known as phospholipid bilayers. All transmembrane proteins are integral membrane protein but not all integral membrane protein are transmembrane proteins.
Integral membrane proteins function as a transporter, receptors, channels, proteins which is responsible for cell adhesion, proteins are also Involved in transduction and build up of energy.
Membrane proteins are class according to their transmembrane domain properties. The N-terminus of an integral membrane protein type I is in the endoplasmic reticulum lumen, where N-terminus of an integral membrane protein type II in the cytoplasm.
Answer: Photosynthesis is process of green plants and organisms use sun or UV light to <u>synthesize </u>from CO2 (carbon dioxide) and water to make food. Usually producing green pigment called chlorophyll (what makes leaves green) and oxygen as a byproduct which they do not need.
The right option is; d. Runoff describes water movement and infiltration describes water storage.
Runoff is the portion of precipitation, irrigation or snow melt that flows over land as surface water instead of infiltrating or evaporating. Factors that influence runoff are permeability, amount of rainfall, slope and vegetation.
Infiltration is the process by which water or precipitation on the ground surface moves into the soil. Factors that determine the rate of infiltration include; soil type, topography of the land, amount of precipitation, vegetation, and pre-saturation levels.
The valves in the heart make sure that blood goes in only one direction. For example, when blood is pumped from the left ventricle the mitral valve won't allow the blood to come back into the left atrium. And the aortic valve will prevent the blood from coming back into the left atrium from the aortic arch.
? could you type it out kinda hard to see
