The provided question was incomplete as it lacks the options. However, the correct option for this question is as follows:

an electronic balance to measure the volume of soil in which each corn plant is grown

a graduated cylinder to measure 30 mL of water for each plant daily

a metric ruler to determine the mass of each plant each week

a Celsius thermometer to determine the pH of the soil

Answer:

The correct answer is - a graduated cylinder to measure 30 mL of water for each plant daily

Explanation:

The basic knowledge requires to answer this question, as it is not asking about the photosynthesis or temperature of the air but the tool which is correctly matched, so let's get the answer from the options:

the first option is talking about the electric balance and measuring the volume of soil with it, as wee know electric balance measures mass or force on the pan downwards which is the mass of the substance. so it is an incorrect match.

Graduated cylinder to measure the 30 ml water which is correct as this tool measure volume of liquid or substance.

A metric scale measures distance or length of an object, not the mass thus, it is an incorrect match.

A thermometer measures the temperature, not the pH of a substance so it is also an incorrect match.

Eric has blood type O. What could be the genotype of his grandmother Tricia? Select all that apply.
sleet_krkn [62]

Answer:

C. IBIB

D. IBiO

Explanation:

The blood group system comprises of three different kind of alleles, iA, iB, IO. As we know that a person gets two alleles for both traits, one from father and one from mother, and based on that a person gets its blood group. IA and IB are dominant to IO.

So, if a person has genotype IAIO he will have blood group A and if he has genotype IOIB he will have blood group B because A or B are dominant to O.

However, if a person has blood group O it means that he has genotype IOIO.

So, in this diagram we see that Eric has blood type O, which means that his genotype will be IOIO.

The Eric's mother Melissa has blood group B, which means that she can either had genotype IOIB and IBIB respectively.

Similarly, Eric's grandmother Tricia has genotype  B which means that she can have genotype both  IOIB and IBIB respectively.

Therefore, both C and D are correct options.

Explain the difference between a pseudocoelom and a true coelom
ohaa [14]

Answer:

A pseudocoelom is a body cavity that lies between mesodermal and endodermal tissue and is, therefore, not completely surrounded by mesodermal tissue. A “true” coelom is completely surrounded by mesodermal tissue, and can thus be subdivided into compartments.

Describe a hypothetical result of the fluctuation test that would have supported the hypothesis that mutations occur in response
OlgaM077 [116]

In order to support the hypothesis that mutations occur in response to an environmental challenge, the experiment in question would have to show an increase in mutation rates shortly after the environmental challenge was introduced.

When we test a hypothesis, we perform an experiment and gather data over the course of the testing. In order to obtain evidence that supports a hypothesis, we have to ensure that only one variable is changing and be sure to repeat the experiment to confirm the values measured.

Taking this into account, a hypothetical result of the fluctuation test that would support the hypothesis of mutations in reaction to environmental challenges would be to measure a spike in mutation rates in the generation following an environmental challenge, and then continue to do so with future post-challenge generations.
