2. I Love Popcorn!
Jason wanted to find out how he could increase the number of popcorn kernels that pop when
1
cooked. He hypothesized that more kernels would pop if he used more oil. To test this, he placed
100 kernels of "Pop Rite' popcorn into a popcorn popper that contained different amounts of oil. He
used the following amounts of oil: 5 ml, 10 ml, 20 ml, and 30ml. He used 5 ml of oil as the control.
Header
He conducted the test 3 times for each amount of oil. He then counted the number of kernels that
had popped. Each time he heated the oil for 2 minutes and cooked the popcorn for 4 minutes.
Hypothesis: I think the popcorn with the most oil will have the most popped kernels because the hotter
all the oil gets and the more oil there is in it, then the kernels will be able to pop faster. What are the:
Independent Variables:
Dependent Variables:
Controlled Variables:

Answers

Answer:

Independent: amounts of oil

Dependent: amounts of popped kernels

Controlled variables: Kernel brand, cooking time, popping time

Explanation:

Independent variables are what are changed in the experiment. The dependent variables depend on the independent so they are what is affected each time. Usually this is what is being tested for. Controlled variables are those that aren't being tested and are kept the same each time to make sure it doesn't change the outcome.

isoleucine

Answers

Answer:

asparagine

Explanation:

take a look at the graph attached, it helps identify codon sequences.

The codon AAC codes for the amino acid asparagine. Asparagine is a non-polar, neutral amino acid that is found in all living cells. Hence option C is correct.

It is involved in a variety of cellular processes, including protein synthesis, cell signaling, and energy metabolism.

The other answer choices are incorrect. Serine is coded for by the codon AGU or AGC. Lysine is coded for by the codons AAA or AAG. Isoleucine is coded for by the codons AUA, AUC, or AUU.

Therefore, option C) asparagine is correct.

You are required to make 10mL of a 0.5M solution of HCl. Your stock solution of HCl is 90M. Using distilled water (dH2O) as a solvent, how much of each component will you need to make the desired final solution?

Answers

Answer:

0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.

Explanation:

From the dilution equation:

Initial molarity (m1) x initial volume (v1) = final molarity (m2) x final volume (v2).

In this case, m1 = 90 M, v1 = ?, m2 = 0.5 M, and v2 = 10 mL

v1 = m2 x v2/ m1 = 0.5 x 0.01/90 = 0.0000556 L

v1 = 0.0556 mL

This means that the initial volume of 90 M HCl to be taken is 0.0556 mL. Since the final volume to be prepared is 10 mL,

 10 - 0.0556 = 9.944 mL

Hence, 0.0556 mL of 90 M HCl would be taken and 9.944 mL distilled water added to make 0.5 M, 10 mL HCl solution.

what similarities would you expect to find in highly resilient ecosystems

Answers

Answer and explanation:

An ecosystem that is highly resilient is one that has the capacity to resist subjected damage by maintaining its normal patterns of biomass production and the cycling of nutrients. This damage can be anything from fires to deforestation.

A highly resilient ecosystem can be expected to adapt well to change, sometimes permanently, to survive indefinitely. For an ecosystem to be resilient, it has to be flexible and be able to adjust to uncertainty. Highly resilient ecosystems tend to have reproductive cycles, trophic cascades, and population connectivity - all of these characteristics give these ecosystems better chances of surviving different types of disturbances.
