Answer:
C) relaxation of the internal urethal sphincter
Explanation:
The muscles that control micturition are controlled by the autonomic and somatic nervous systems.
Micturition is inhibited (storage phase, when bladder is at low volume) when internal urethral sphincter are contracted and the detrusor muscle relaxed by sympathetic stimulation. During micturition, parasympathetic stimulation leads to the detrusor muscle contraction and the internal urethral sphincter relaxation. The external urethral sphincter is under somatic control and is consciously relaxed during micturition.
Answer:
1. Thylakoid
2. Water
3. Oxygen
4. Glucose
Explanation:
Photosynthesis is a unique process where autotrophs make their own food. It is a metabolic activity that occurs in the Chloroplast. Photosynthesis occurs in two main stages viz: light dependent stage and light-independent stage. The light dependent stage, which occurs in the thylakoid lumen of the CHLOROPLAST. It involves the capturing of light energy from the sun using the Chlorophyll pigment. The Chlorophyll molecule gets excited and the energy derived is used to split water molecule in a process called PHOTOLYSIS OF WATER.
The protons derived from this is used to build a proton pump that will facilitate the synthesis of ATP. A reduced electron carrier (NADPH) is also produced. Oxygen gas is released as a byproduct in this stage.
In the light independent stage, also known as Calvin cycle, the NADPH and ATP produced in the first stage is used to synthesize glucose molecule.
C. Combine with hemoglobin to form oxyhemoglobin
I'm pretty sure that this is the correct answer "The enzymes in the second test tube must have denatured at 1000C, since most enzymes degrade at such high temperatures." that is if you're using Plato, in which case this would be one of your answer choices.
