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:
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.

c. rotates from west to east.
d. none of the these.
Answer:
B. Rotates from east to west.

Ben makes five paper helicopters with different when leaves he drops them at the same from a height of 2 measures 4/5 Chelsea Pier acquired the amount of the time it takes for each helicopter to Fox and crafts what is the independent variable
Answer:
The question is unclear, however, it can still be answered based on understanding of the topic, with correct explanation.
The independent variable is the HELICOPTERS MADE FROM DIFFERENT MATERIALS
Explanation:
The independent variable in an experiment is the variable that the experimenter manipulates or changes in order to effect a response in the dependent variable. The independent variable is also called the experimental variable.
In this case, Ben makes five paper helicopters using different materials and tests the amount of time each paper helicopter will take to fall. Hence, the PAPER HELICOPTERS MADE FROM DIFFERENT MATERIALS is the independent variable, which determines how long they will fly (dependent variable)
Why consumer in a food chain can’t get access to all energy in food chain?
Please I really need the answer
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. A food chain can usually sustain no more than six energy transfers before all the energy is used up
Explanation:
how are elements related to why different materials are used to make different products
Answer:The atoms of different elements are held together in compounds by chemical bonds. ... The properties of a compound depend not only on which atoms the compound contains, but also on how the atoms are arranged. Atoms of carbon and hydrogen, for example, can combine to form many thousands of different compounds.

Structure has no apparent function in a species, but is fully functional in the species' ancestors.
a) true
b) false
Answer:
The correct answer would be - True.
Explanation:
In several organisms have structures, has no apparent role in the particular species and are residual parts from a past ancestor, but these structures were fully functional in the ancestors of the species. These structures are called vestigial structures or organs.
The example of such structures are, wings of the flightless birds, appendix of human and many other, all these structures has no function in the body of the individuals of the particular species but is fully functional in ancestors.
Thus, the correct answer is - true.

b. pancrease; digestive; endocrine.
c. ovary; female reproductive; lymphsatic.
B. Pancreas; Digestive, Endocrine
The pancreas is an organ directly associated with the digestive and Endocrine systems.
What is Endocrine system?A intricate system of glands and organs makes up the endocrine system. Your body's metabolism, energy level, reproduction, growth and development, and response to injury, stress, and mood are all regulated and coordinated by hormones.
The endocrine system is made up of the following components:
The optic chiasm, where the optic nerves behind each eye intersect, and the hypothalamus are both found at the base of the brain. In the center of the brain, beneath the corpus callosum, is where you'll find the pineal body.
Therefore, The pancreas is an organ directly associated with the digestive and Endocrine systems.

what similarities would you expect to find in highly resilient ecosystems
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.

If you have an experiment in which there are 4 different groups, and the same variable is manipulated in all of them, is there a control group?
Answer:No
Explanation:I believe it is no due to the fact that the variable is being manipulated in all groups and in order to be a control groups the variable must remain the same or must not be manipulated.

3. What is another name or a sub-property of cohesion? Give an example of how this affects living
organisms
Answer:
Unity is the other name of cohesion.
Explanation:
The property of cohesion is to sticking together of something. The molecules of liquid stick together with the help of cohesion. This cohesion property is very important for plants because with the help of this property, plants take water through roots from the soil and the water molecules are stick together with the help of cohesion. If cohesion is not present then the uptake of water can not be possible.

9. AAC is a codon that codes for the amino acid:
serine
lysine
asparagine
isoleucine
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?
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.
