What determines the carrying capacity of an ecosystem?
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

Answers

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.

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

Answers

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

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.

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.

why is the tongue considered 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.

Answers

Having more data would make the average height less affected by one or two plants that are randomly shorter or taller.

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.

What would happen if a plant cell is placed in a solution of salt?

If a higher concentration of salt is placed outside of the cell membrane, the water will leave the cell to bond with it. The loss of water from this movement causes plant cells to shrink and wilt. This is why salt can kill plants; it leaches the water from the cells.

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.

Why is it important for molecules to able to travel into and out o your body's cells?

Answers

It’s important there’s molecules that could do so for keeping homeostasis, food movement, keeping the cell isotonic with movement of water, glucose to go into cell to not let it starve and waste to escape and not build up in cell

The function of the transport proteins is to maintain the internal environment of the cell's salt, nutritional, and protein balance within a range that ensures the survival of the cell and the organism.

What is importance of a molecule to move across the cell?

Biology places a great deal of importance on the passage of substances into and out of cells (for example, nutrients into and poisons out), as without it, no cell and hence no organism could survive for very long.

Moving chemicals throughout the body is essential for living cells. Transporting chemicals into and out of cells is necessary.

Examples include oxygen, carbon dioxide, and dissolved food. Active transport, osmosis, and diffusion are used to accomplish this.

Therefore, transport of a molecule into and out  of cell is important to functioning of cell.
