D= m/v
solve this formula to find v
by solving we get,
v = m/D
v = 13/19.3
v = 0.67 cm^3

2. Name three process which move carbon from one reservoir to another, apart from to and from the
skelet666 [1.2K]

Answer:

The three processes are:

  1. Cellular respiration
  2. Decomposition
  3. Fossilization

Explanation:

  • The process of cellular respiration, carried out by all living organisms, involves the catabolic break down and conversion of carbon containing molecules especially glucose (6-carbon) into ATP and energy yielding compounds such as NADH and FADH2. This energy helps drive cellular processes for daily bodily functions.
  • C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
  • Decomposition involves the conversion of living matter into simpler compounds by the action of special organisms called decomposers. This group principally includes bacteria and fungi. Bacteria and fungi degrade matter with the help of their enzymes and release nutrients into the soil. This process is a rich carbon and nutrient source for the plants and other soil borne organisms.
  • Fossilization is the process of preservation of living organisms in the form of rocks or sediments. Over millions of years and under intense pressure and temperature, these remains are converted into rich carbon sources such as coal, natural gas and oil. Therefore, this process converts carbon in the living system to fossil fuels.

What we need to do for speed up photosynthesis
Margarita [4]

Answers:

The ways to speed up photosynthesis is to <u>increase the amount of light </u>because with minimal light it slows photosynthesis down. Photosynthesis is also <u>dependent on temperature</u> and when the enzymes reach the perfect temperature which is around <u>50-68 degrees fahrenheit. An increase in carbon dioxide </u>will also speed up photosynthesis (this is more possible in a greenhouse). Carbon dioxide is used to make the sugar in order to create the reaction for photosynthesis to happen.

What is required before a hypothesis advances to the status of a scientific theory ?
Vesna [10]
<span>The hypothesis has to survive all attacks on it and continue to provide the best known explanation of the known data. In the scientific method, there are several steps towards the creation of a hypothesis and eventually a theory.
 1. Gather data. 
 2. Construct a hypothesis that explains the data. This hypothesis should be capable of being disproved and should be capable of making predictions.
 3. Gather more data. DO NOT cherry pick only that data which supports the hypothesis . If data is uncovered that contradicts the hypothesis , revise or replace the hypothesis.
 4. After the hypothesis has survived all attacks on it and is the best known explanation of the data, then it becomes a theory.
 5. Note, data collection continues after the hypothesis became a theory and if new data is discovered that is in conflict with the theory, then the theory is modified, or discarded in favor of a new hypothesis or theory.</span>

What does each phase of mitosis look like
Sphinxa [80]
Interphase: You could not distinguish any parts of the cell.
Prophase: You could clearly see the chromosomes throughout the cell.
Metaphase: The chromosomes where lines up in the middle of the cell.
Anaphase: You could see the chromosomes were separated to ether side of the cell.
Telophase: The entire cell was separated to each side but was not split into its own cell.
Cytokinesis: In this step the cell had totally separated and there was now two separate daughter cells.
