Answer:
The main role of DNA in the cell is it's a Long term storage of information
Explanation:
The main role is to read the genetic code, cells make a copy of a stretch of DNA in the nucleic acid RNA
A plant and animal cell is eukaryotic
a eukaryotic cell has a nucleus instead of floating DNA which a prokaryotic cell has
Answer:
A hypothesis is a possible explanation for a set of observations or an answer to a scientific question. A hypothesis must be testable and measurable. This means that researchers must be able to carry out investi- gations and gather evidence that will either support or disprove the hypothesis.
Explanation:
A serum calcium concentration of this range only means
that the cancer must be suspected to be a malignant one. So the nurse should
suspect that the malignancy of the cancer is what is causing the electrolyte imbalance
of the patient.
Answer:
Explanation: Although cellular respiration has multiple parts, the basic chemical equation is:
Answer: Oxygen
Explanation: Oxygen + Glucose (sugar) = Carbon Dioxide + Water + Energy (ATP)
This equation is often broken into two parts, the reactants and the products. Reactants are the molecules that begin cellular respiration, in this case that would be oxygen and glucose. Products are what forms during cellular respiration. Here, the products are carbon dioxide, water, and energy. As the focus of this lesson is on the reactants of cellular respiration, oxygen and glucose, let's take a look at those.
Reactants--
The first reactant in the equation for cellular respiration is oxygen. Most people are familiar with oxygen since it's the primary gas needed for sustaining our lives. We obtain oxygen by simply breathing. Oxygen is highly reactive and therefore perfectly suited for driving chemical reactions such as cellular respiration. However, people may be less familiar with the second reactant in our respiration equation: glucose.
