Well part of the water cycle is evaporation which come from heat which you get from the sun. When the water evaporates it goes into clouds so then it can rain.
Hope this Helps
Answer:
B) Oxygen and E) Carbon Dioxide
Explanation:
Cellular respiration has a general chemical equation as:
⇒
glucose + oxygen ⇒ carbon dioxide + water
Photosynthesis has a general chemical equation as:
⇒
carbon dioxide + water ⇒ glucose + oxygen
Reactants are on the left side of the equation while products are on the right. You can see that the products in cellular respiration are carbon dioxide and water, these also are the reactants in photosynthesis. So (B) Oxygen and (E) Carbon dioxide are the answers.
Answer:
a. The formula for finding the number of colonies in a given volume is,
CFU/ml, here CFU is the colony forming units or the number of colonies formed in a volume plated in ml × dilution
The dilution factor given in the question is 1 × 10⁻⁴ and the number of colonies given is 186. Therefore, the number of bacteria present in the given 1 ml of the milk is,
CFU/ ml = 186 / 1 × 10⁻⁴ = 186 × 10⁴.
Hence, the concentration of bacteria in the milk is 186 × 10⁴ CFU/ml.
b) The limit of the bacterial concentration in the pasteurized milk is 20000 CFU/ml, however, it can be seen that the sample of the milk possess more concentration of bacteria than the desired value. Therefore, the milk is not safe to drink by Public Health Standards.
C. Lithosphere
Lithosphere is where crust, landforms, etc. can be found.
Answer:
E. The percentage of viable, fertile hybrid offspring formed if the two populations encounter each other.
Explanation:
The biological species concept is a concept which is about a group of potentially interbreeding populations which become reproductively isolated from other groups of the same species.
- These groups cannot reproduce with one another when they encounter each other.
- Testing the frequency of viable offspring is a good way to prove the biological species concept in a certain species
