Answer:

hailstones --> Hail is a type of precipitation, or water in the atmosphere. Hail is formed when drops of water freeze together in the cold upper regions of thunderstorm clouds. These chunks of ice are called hailstones. Most hailstones measure between 5 millimeters and 15 centimeters in diameter, and can be round or jagged.

i am sorry i can not answer the oxygen question because it is not all there.

Why are cellular respiration and photosynthesis considered opposite reactions

Andreas93 [3]

Explanation:

They are opposites because they are the same chemical reaction but reversed. Cellular respiration takes glucose (from nutrient/food) and oxygen (from atmosphere) in order to make CO2 (think about exhaling) and H20 (water).

What are the weakest of all scientific findings? Group of answer choices Case studies Correlational studies Experimental studies

goldenfox [79]

Answer:

The weakest of all scientific findings are given by case studies.

Explanation:

Case studies are observational or descriptive studies focalized on the analysis of a particular object (an individual, place, event, etc.) in a specific situation. Beacuse of its descriptive nature, it does not provides information about cause-effect relationships and does not consider the effect of random variations. It is the weakest of all scientific findings.

Correlational studies involves measurements of at least two different variables and try to identify if there is a specific relationship between variables, it means if there is a specific trend in the variation of one variable as a response to the variation in the other one (for example, when the temperature of a given solution increases, the solubility of the solute also increase). Although this kind of studies does not provides information about cause relationships, the trend between variables are well stated.

Experimental studies are the ones in which a researcher makes sure of providing a controled environment and manipulates a particular variable to see responses of one or more different variables. These studies provides well supported information.

Epidemiological studies the purpose to analyze all the factors involved in an epidemic (causes, incidence, evolution, etc.). It includes observational and experimental studies that complement each other. Because of the importance of these reasearch on public health, their scientific findings are well stablished and supported.

Summarizing, the weakest of all scientific findings are provided by case studies.

azamat

The correct answers are ATMOSPHERE and BIOSPHERE. Nitrogen is most abundant in the ATMOSPHERE, but nitrogen can't be absorbed by the BIOSPHERE without the help of a special bacteria and without undergoing a process called nitrogen fixation.

Give an example of an amino acid being coded for more than one codon

Serhud [2]

Many of the amino acids are coded for by more than one codon. Examples are:

1. Isoleucine - ATT, ATC and ATA

2. Leucine - CTT,CTC,CTA CTG, TTA and TTG.

3. Valine - GTT, GTC, GTA and GTG.

4. Phenylalanine - TTT and TTC.

5. Cysteine - TGT and TGC

6. Alanine - GCT, GCC and GCG

7. Glycine - GGT, GCC, GGA and GGG.

8. Proline - CCT, CCC, CCA and CCG.

9. Threonine - ACT, ACC, ACA, and ACG.

10. Serine - TCT, TCC, TCA, TCG, AGT and AGC.
