3. Environment
The simplest definition of an ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.
Answer:
Plants can synthesize all twenty amino acids.
Explanation:
Answer:
1. False
2. False
3. True
Explanation:
1. Compliance is the capacity of a container to increase in size to allow it hold more content. Blood vessel, arteries and veins expand (increase in volume) to be able to accommodate a surge in blood flow, which is as a result of an increase in pressure of the blood from the heart pumping of the blood
Therefore, compliance in the tendency for blood vessel volume to increase as the blood pressure <em>increases</em> not decrease
The statement is false
2. A large compliance is indicative of being highly sensitive to changes in pressure
Compliance, C = ΔV/ΔP
From the above equation, a blood vessel with a large compliance, exhibit a large increase in volume when the increase in pressure is small
Therefore, the statement 'Blood vessels with a large compliance exhibit a small increase in volume when pressure increases a small amount; is false
3. The compliance of the vein ranges from 10 to 20 times (30 times in some literature) greater than arteries. A factor which can be affected by the vascular smooth muscle contraction or relaxation
Therefore, the statement, 'venous compliance is approximately 24 times larger than arterial compliance, so as venous pressure increases the volume of veins greatly increases' is true
Stroma, in a biological explanation, the fluid in between grana, where carbohydrate formation reactions occur in the chloroplast of plant cells photosynthesizing.
Explanation:
Part A
In the bright daylight, the Calvin cycle happens indoors in the stroma. throughout the Calvin cycle, the results ATP and NADPH are conventional convert molecules of carbonic acid gas into high-energy sugars.
Part B
In the darkness, the Calvin cycle conjointly occurs within the stroma. through the Calvin cycle, the products ATP and NADPH are used to change molecules of CO2 into high-energy sugars.
Part C
There will be a decrease in the products ATP and NADPH if the plants are unbroken within the dark for a protracted time and also the Calvin cycle can't be sustained.
