What would happen if a plant cell is placed in a solution of salt?
How could increasing the number of plants help you decrease error in the experiment? Check all possible reasons.
It would increase the sampling error.
It would reduce the significance of any single measurement error.
It would make calculations easier.
Having more data would make the average height less affected by one or two plants that are randomly shorter or taller.
It would make a plant’s death less of an issue.
Answer: Increasing the number of plants in an experiment will help decrease the error, because you have more test subjects to run the test on.
Explanation:
The more subjects that you have have the more tests you can run, this will give you a chance to get more accurate and consistent results. When completing an experiment, you normally have to run 5 or more tests in order to get a goos set of data. So by increasing the number of plants you test on, you'll be able to get a better set of data.
why is the tongue considered an organ?
Answer:
The tongue can be viewed as an organ. It’s comprised of various tissues that give it its own functions that no other organ can replace, it has its own innervation, irrigation, lymphatic and venous drainage. Those are the characteristics that define an organ.
Answer:
Hmm.
Explanation:
The tongue is considered an organ because it has a special job to do.
'Organ, in biology, a group of tissues in a living organism that have been adapted to perform a specific function.
'The tongue is a muscular organ in the mouth of most vertebrates that manipulates food for mastication and is used in the act of swallowing. It has importance in the digestive system and is the primary organ of taste in the gustatory system.'
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.

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.

a. the number of different types of organisms in an ecosystem
b. the amount of available resources
c. the square mileage it encompasses
d. the ratio of biotic to abiotic factors
Answer:
the answer is B. the amount of available resources
Explanation:
The carrying capacity of an ecosystem determines the amount of available resources. Therefore, option B is correct.
What is an ecosystem ?The term ecosystem is defined as the community or group of living organisms that live together and interact with each other in an environment. The biotic and abiotic components are linked together through nutrient cycles and energy flows.
Ecosystem plays an important role to purify our air, maintain our soil, regulate the climate, to clean our water, recycle nutrients and provide us with food. They are at the foundation of all civilization and sustain our economies.
The carrying capacity of an ecosystem determines the amount of available resources. Carrying capacity depends on many abiotic and biotic factors in the ecosystem.
Thus, option B is correct.

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.

How can you analyze data using various types of graphs?
(Science)
A researcher measured the temperature at which two different samples of double-stranded DNA denature (separate into single strands) Sample 1 denatured at a significantly lower temperature
than sample 2 did. Based on the data, the researcher claims that the DNA in sample 2 is composed of a higher percentage of guanine and cytosine than the DNA in sample Ils
Which of the following best supports the researcher's claim?
Sube
The bonds between guanine and cytosine are covalent bonds, which require more energy to disrupt than those between adenine and thymine
B
Guanine cytosine pairs denature at a higher temperature because they have more hydrogen bonds between them than adenine-thymine pairs do
с
Aderine thyminepalis require less energy to separate because adenine and thymine are both single-ring bases
D
Guinine cytosine pas require more energy to separate because one is purine and one is a pyrimidine
Answer:
The correct option is b
Explanation:
There are four nitrogenous bases that can be found in a DNA molecule; Adenine, Thymine, Guanine and Cytosine. The adenine on one strand can only bond (hydrogen bond) with the thymine on the complimentary strand (to form base pair) and vice versa while the guanine on one strand can only bond (hydrogen bond) with the cytosine on the complementary strand (to form base pairs) and vice versa.
There are three hydrogen bonds between Guanine and cytosine base pair while there are two hydrogen bonds between adenine and thymine base pair; hence, DNA samples with higher guanine-cytosine base pairs denature at a higher temperature than DNA samples with lower guanine-cytosine base pairs or with more adenine-thymine base pairs. This is because, it requires more energy to break the triple bonds between the guanine-cytosine base pairs than the double bonds of adenine-thymine base pairs.
From the description above, we can deduce that the correct option is b

the correct answer is D

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.

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.
