Answer:
A student can measure the number of gas bubbles given off by the algae.
Explanation:
- Photosynthesis is the process where green plants convert light energy into the fuel energy for their development and activities.
- Algae is also involved in the photosynthesis process, so the it releases the gas bubbles.
- The oxygen emission process is done by secreting the bubbles by green plants during photosynthesis process.
- So to know about the photosynthesis rate the number gas bubbles, really helps a lot.
A. Substrate
B. Active site
C. enzyme
D. Products
Answer:
11.7 g in 1 L of water.
Explanation:
Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.
It is defined as mol/ L (number of moles per litre).
0,2 M means we have 0,2 mol/ L
In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol
= 
X= 
X= 11.69 g
The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.
Some of the evidence comes from fossils, and some comes from studies that show how similar living things are to one another. By the 1930s, scientists had also learned about genes. As a result, they could finally explain how characteristics of organisms could pass from one generation to the next and change over time
