Answers

Answer 1

Answer:

C!!

Explanation:

It's not B because it's located in the great plains. Not D because in 50 years, 70% of the aquifer will be gone. Not A because water use isn't regulated.

Answer 2

Ogallala Aquifer is the rock holding the groundwater in the Great Plains of America. The Ogallala Aquifer is running out of water.  Thus, option C is correct.

What is Ogallala Aquifer?

Ogallala Aquifer is an underground layer of water that is held by the rocks, pebbles, and gravel that make the water well above the surface. It is not beneath the East Coast but is situated on the Great Plains of the United States.

It has been reported that the water usage of the Ogallala Aquifer is not regulated and hence it does not have enough water to last up to 6,000 years. At approx 70%, the water of the aquifer will be soon gone resulting in the deprivation of the water.

Therefore, option C. the Ogallala Aquifer is running out of water is correct.

What does relative humidity measure?

Answers

Relative humidity (RH) (expressed as a percent) also measures water vapor, but RELATIVE to the temperature of the air. In other words, it is a measure of the actual amount of water vapor in the air compared to the total amount of vapor that can exist in the air at its current temperature.

In comparison to the greatest amount of moisture that might be present at that temperature, relative humidity measures how much moisture is really in the air.

The amount of moisture in the air as compared to the maximum amount that might exist at given temperature is measured as relative humidity. It shows how saturated the air is with water vapour and is given as a percentage. A greater relative humidity signifies that the air is drier and is more likely to be approaching its maximum moisture-holding capacity than a lower relative humidity.

Explanation:

The second generation of a purebred cross of a h.o.m.o.zygous recessive organism, with a h.o.m.o.zygous dominant organism, contains a ratio of approximately ____ expressed dominant traits to recessive traits.
a. 1:1
b. 1:3
c. 2:1
d. 3:1

Answers

Answer:

d. 3:1

Explanation:

A purebred organism is an organism that contains identical alleles for a particular gene e.g rr or RR. According to this question, in a cross between a purebred dominant organism e.g RR and a purebred recessive organism e.g rr, each parent will produce R and r gametes respectively.

Using the gametes in a punnet square (see attached image), a heterozygous organism (Rr) will be produced in the F1 generation. If these heterozygous organism is self-crossed i.e. Rr × Rr, the following F2 offsprings will result;

RR, Rr, Rr, and rr.

RR, Rr and Rr will exhibit dominant traits while rr will exhibit recessive traits. This means that the F2 generation contains a ratio of approximately 3:1 expressed dominant traits to recessive traits.

The process of transcription is known to have a less effective “proofing” stage to check the sequence of bases than does the process of DNA replication. What effect does this have on the base sequences produced by transcription?

A.Errors in the base sequences will result in a damaged strand of DNA.

B.The base sequences of mRNA can be exactly the same as those on DNA.


C. It is more likely that there will be more errors in coding base sequences in mRNA than there will be in DNA.

D. It is more likely that there will be fewer errors in coding base sequences in mRNA than there will be in DNA.

Answers

Transcription produces mRNA and dna replication produces DNA. If transcription has less effective proofing it will make more errors. These errors are mutations that can affect the eventual protein produced.

Therefore C: it is more likely there will be errors in the base sequence of mRNA ( the nucleotides that make it up) than in DNA.

A strong UREA solution is a common reversible denaturant. Additional treatment with 2-mercaptoethanol completely denatures proteins that contain disulfide bonds.

Denaturing reversible agents can alter the secondary/tertiary structure of a protein without altering its primary structure.

Urea is a reversible denaturant that breaks hydrogen bonds in the secondary structure of proteins without modifying the primary structure.

2-mercaptoethanol is a denaturing agent that cleaves disulfide bonds between cysteine residues.

In conclusion, a strong UREA solution is a common reversible denaturant. Additional treatment with 2-mercaptoethanol completely denatures proteins that contain disulfide bonds.

A farmer decides to test whether or not a fertilizer will make her crops grow bigger. In year 1, she plants corn in two different fields on her property and fertilizes one and not the other. She measures the height of 10 corn plants in meters from each field. She takes her measurements every week for three months. In year 2, she puts irrigation in one of the fields and conducts the same experiment.

Required:
a. What is the independent variable and the treatments (increments) used in the experiment?
b. What is the dependent variable and the units in which it was measured?
c. Name at least two controlled variables:
d. What is the hypothesis?
e. Identify two sources of error in the first year in the experiment:
f. Identify two sources of error in the second year in the experiment:

Answers

Answer:

a. independent variable: the fertilizer.

   treatments: the use of fertilizer in one of the fields.

b. dependent variable: the crop growth in height.

   units: meters

c. two controlled variables: soil pH / solar-radiation exposure, and water supply  

d. hypothesis: the fertilizer makes the crops grow bigger.

e. two sources of error in the first year:

the researcher might plant the two crops under different conditionstake wrong measures of the height of the corns

f. two sources of error in the second year:

she can fail in irrigating the crops climatic and environmental conditions might change and have different consequences on each of the fields (this source affects the results influencing the growth of the plants).  

Explanation:

Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. These changes allow analyzing its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the fertilizer is the independent variable.    Treatments: Refers to the experimental procedure applied in the experimental group. In this example, the use of fertilizer is the treatment. Here the experimental group (the one that receives the experimental procedure, with changes in the independent variable) is the fertilized field. Data from the experimental group is compared with the data from the control group, to analyze the effects of the fertilizer.Dependent variable: The values of these variables respond to any change in the independent variable. It represents the quantity of something. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, the crop growth rate in height is the dependent variable, that depends on the fertilizer used in that field. The units in which the crop is measured are meters in height.        Controlled variable: Refers to those variables equally applied to every group or subject in an experiment and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example, soil pH and solar-radiation exposure can be two controlled variables, as they must be equal for both fields. Water supply by irrigation ducts during the second year in both fields is also a controlled variable.     Hypothesis: A hypothesis is a possible answer for a question, a speculation that is not verified yet and requires corroboration. A hypothesis must express what is expected to occur in a perfectly comprehensive manner. It must be objective and directly related to variables. In this example, the hypothesis might be that the fertilizer makes the crops grow bigger.          Errors: These are the differences between the observed data or taken values and what is really happening in nature, which can lead to a misinterpretation of what is actually going on. These errors might be systematic mistakes performed by the researcher when measuring, taking data, applying the treatment, etc. Or they might be due to random errors, which are due to failures in the instrumentals, changes in the environment,  a single mistake of the researcher while taking measures, among others. During the first year, the researcher might plant the two crops under different conditions (parcels with different slopes which affect solar-radiation) or might commit a mistake while applying the fertilizer (different concentrations for example), or might take wrong measures of the height of the corns. During the second year, she can fail in irrigating the crops correctly, providing more water to one of the fields.  She can commit the same measuring mistakes. Or even climatic and environmental conditions might change and have different consequences on each of the fields.

Define biodiversity and describe how biodiversity (the variety of life in a particular habitat or ecosystem) helps keep an ecosystem healthy.

Answers

Answer:

Biodiversity is a variation of organisms (plants, animals and bacteria) in the world or a specific habitat. Biodiversity helps to keep an ecosystem healthy because there is more variation of food and different organisms can rely on each other for survival. Also it offers a larger more reliable food chain and if one species is suddenly wiped out, it won't impact the ecosystem as much as it would if the biodiversity was smaller.

Answer:

D) repeatedly back and forth through living and nonliving parts of the ecosystem

Explanation:

Matter is contained in both living and non-living components of the Earth. An atom is the smallest indivisible component of every matter. This means that matter is made up of atoms.

In an ecosystem, organisms feed on one another in order to survive. However, as they do this, matter is transferred from one organism to another. This transfer of matter (atoms) occurs repeatedly repeatedly back and forth in a cyclical manner through living and nonliving parts of the ecosystem.
