Chargaff's law and Rosalind Franklin's discoveries
<span>Cells of most organisms freeze due to the fact that. Water is less dense as a solid than as a liquid. To elaborate when you quickly freeze and organism the internal portion of that organism is freezing at a much slower rate. SO the outside portion becomes rigid eventually breaking is you freeze it at a slower rate less cells will be damaged.</span>
Answer:
The correct answer is:
Includes at least two groups, one of which does not receive the experimental treatment. (B)
Explanation:
A controlled experiment is made up of at least two groups of participants (subjects). One group (the test group) receives the experimental treatment, which can be an intervention or a new drug to be tested etc, and the effect of the treatment on the subjects is measured, while the second group of similar subjects also known as the control group acts as a baseline and do not receive the treatment or intervention. They act as a baseline to ensure that the change observed in the treatment group was brought about as a result of the treatment.
<em>Note that repeating the experiment several times does not ensure accuracy of the result, rather it ensures reliability of the results hence option D is not correct</em>
Answer:
The answer is below
Explanation:
To improve this condition, there are various means or ways to combat this, some of which are:
1. Carrying out improvement on nutrition
2. Eliminating or reducing the environmental degradation on the food system by making food supplies more diverse, nutritious and sustainable.
3. Increasing the Plantation of agricultural produce, most especially food.
4. Birth control: this is trying to measure the resources available against the population, to achieve optimum relationship between population and resources.
5. Ensuring Organic Pesticides are used in agriculture, to avoid or prevent contamination of foods.
6. Provide proper Irrigation system, such that most area can serve the purpose of of agriculture.
7. Ensure the use of quality Seeds, which can translate to to bounty harvest
8. investment is needed to facilitate innovations and development of interventions that can improve nutrition in a cost-effective, sustainable way.
9. the private sector needs to be engaged in a meaningful way in finding solutions to a more sustainable and nutritious food system.
While looking at a cell under a microscope, a scientist is able to see a
biological molecule. This molecule is a nucleic acid with double
strands and
<span>
contains the nitrogenous bases adenine, thymine, cytosine, and guanine. Based on this information, the scientist can conclude that </span>"
The nucleic acid is DNA and would be found in the cell’s nucleus."
