It is necessary for
nurses to join programs about growth and development because this is essentially
what they are dealing with everyday. Since they deal with different age groups,
growth and development is important to know what is normal in all age groups in
order to identify possible abnormalities their patients might face.
Science is an organized way of using evidence to learn about the natural world.
The goal of science is to investigate and understand the natural world, to explain events in thenatural world, and to use those explanations to make useful predictions.
The Scientific Method Itself:
I. Observations:
Whether they start with a problem or not, scientists make careful observations.
Observations are a way to collect data (recorded observations or information) about events or processes in a careful, orderly way, using the senses (sight, hearing, touch, taste and smell).
Two types of data include:
a) Quantitative data: Are observations which collect data that can be directly measured or counted.
b) Qualitative data: Are observations involve making careful descriptions or drawings and do not involve numbers.
Inference: A logical interpretation of an observation based on prior knowlege. An educated guess as to what is occurring.
II. Hypothesis:
A proposed scientific explanation for a set of observations. Scientists devise hypotheses based on logical inferences, prior knowledge and informed, creative imagination.
Hypotheses may be tested by controlled experiments, or by collecting additional data.
III. Controlled Experiment:
A way to test a hypothesis by testing a single variable by changing it while keeping all other variables the same.
Variable: Any factor during an experiment that could change and affect the results (Examples: Temperature, pressure, amount of light, color of light, human error, etc......)
Manipulated variable: The factor in an experiment that is deliberately changed to test the hypothesis.
Controlled variable: any factor during an experiment that a scientist purposely keeps the same.
During the experiment, a scientist divides the tests into 2 groups, the control setup and the experimental setup.
Experimental setup: The part of the experiment that contains the manipulated variable.
Control setup: The part of the experiment that does not contain the manipulated variable. It may be called the placebo.
Answer:
No, glycolysis can not be continued without fermentation in the absence of oxygen.
Explanation:
In the absence of oxygen, cells perform fermentation to oxidize NADH into NAD+. NAD+ is required during the conversion of glyceraldehyde 3 phosphate into 1,3 bisphosphoglycerate. Fermentation reduces pyruvate and oxidizes NADH so that the NAD+ supply is continued to ensure continuity of glycolysis.
If fermentation does not occur under anaerobic conditions, cells will accumulate pyruvate and NADH. Glycolysis could not be continued in the absence of NAD+.
The answer would be true because since light does not penetrate to the bottom, photosynthesis is limited to the top layer in Lake ! so True !.
Answer:
eukarya
Explanation:
so long as that stands for eukaryotic
fungi is eukaryotic
other 2 are multicellular, and therefore eukaryotic
if u don't like the first explanation, the second one is process of elimination
archaebacteria is a kingdom, so it can't be that, same with plantae.
fungi isn't a bacteria so it can't be that either
only option remaining is eukarya
