Answer:
D. blue-violet and red-orange
Explanation:
The light reactions of photosynthesis use only certain wavelengths of visible light.
Light absorbing molecules known as pigments in the membranes of a granum absorb mainly in blue-violet and red-orange wavelengths. We do not see these absorbed wavelengths. What we see when we look at a leaf are the green wavelengths that the pigments transmit and reflect.
A) A vaccine is developed that prevents individuals being infected
Option A is true about blood pH.
Urine's specific gravity, which is somewhat greater than that of water, is a crucial physical property.
Characteristics of urine:
- Osmolarity is typically harder to quantify than specific gravity, which measures the amount of solutes per volume of a solution. Because there are solutes in urine, its specific gravity is always higher than that of pure water (water = 1.0). Since specific gravity is a less precise predictor of urinary solutes, laboratories may now directly detect the osmolarity of urine.
- Osmolarity, or mOsmol/L, is the measure of how many osmoles or milliosmoles are present in a litre of a fluid. The osmolarity of urine can range from 50 to 100 to 1200 mOsmol/L of water.
Therefore, it is concluded that the correct solution is an option (D), i.e., slightly higher than water.
The complete question is:
An important characteristic of urine is its specific gravity or density, which is ________.
A. the same as water
B. less than water
C. much higher than water
D. slightly higher than water
