The genetic code is based upon reading 3 bases at a time
there are 4 nucleotides bases in DNA and 20 amino acids .
In order to incorporate all the amino acids we consider 3 bases in genetic code
4 x 4 x 4 = 64
if we would take 2 bases -
4x4 = 16 that would leave out 4 amino acids without a code .
Answer:
b. 80g
Explanation:
Three cycles of PCR would produce 3 doublings of the amount of DNA.
Cycle 1: 10x2 = 20pg
Cycle 2: 20x2 = 40pg
Cycle 3: 40x2 = 80pg
This can also be worked out for large cycle numbers by final mass = starting mass x 2ⁿ, where n is the number of cycles.
Answer:
<em>The correct option is A. The Population will decline over time</em>
Explanation:
As the phytoplanktons won't receive enough sunlight, they will not be able to make enough food by photosynthesis. As a result, the phytoplanktons will start to die and they won't be able to reproduce abundantly like before. Hence, the population will decline.
Other options like option B are false because the population will not decrease their need for food. They will start to die due to lack of food and sunlight.
Answer:
Explanation:
First, let's identify the tools needed.
Since the biology class is studying the temperature, they will likely need a <u>thermometer</u>. Also, they are gathering information about the growth of the plants. This could use a <u>balance </u>of a meterstick.
Next, recall the difference between quantitative and qualitative data.
- <u>Quantitative</u>: Measurable and numerical results found using scientific instruments/devices
- <u>Qualitative</u>: Data found using the senses, such as descriptions and diagrams.
Since the class is measuring temperature and growth using tools, it must be quantitative data.
We can eliminate choices A and B, because they claim the class will gather qualitative data. Then, we can eliminate choice D, because a beaker and timer won't help with temperature and growth. That leaves choice C as the correct answer.

yeah I think so because if u look it uppp it said sooo
