According to the flow rate fromula, if blood pressure doubled at the same time that the peripheral resistance doubled, the blood flow through a vessel would be the same, it would not change.
What is blood pressure?Blood pressure refers to the strength applied by the blood against the vessel walls as it flows.
This pressure depends on the strength and volume of the bombed blood as well as by the vessel size and flexibility.
Blood pressure changes continuously according to the activity, temperature, diet, emotional state, among others.
Whast is the peripheral resistance?Total peripheral resistance refers to the resistance offered by the vascular system to the blood flow.
This resistance is due to the friction of the blood against the vessel's walls. In other words, it is the opposition of the vessels to blood flow.
The total peripheral resistance is the summary of all the bloody circuit resistances in the body.
Mechanisms that induce vasoconstriction cause an increase in total peripheral resistance, while vasodilation provoke a decrease in total peripheral resistance.
Flow rateThe flow rate equals the pressure difference divided by resistance to flow.
Flow rate = pressure difference / resistance to flow
According to this formula, if blood pressure doubled at the same time that the peripheral resistance doubled, the blood flow through a vessel would be the same, it would not change.

a beaker cannot be used for measuring the volume of a liquid because
Answer:
Beakers should not be used for measuring a liquid's volume because beakers can be inaccurate. For example, they are typically accurate within 5 percent. Beakers should only be used for approximating volume.
A better choice for accurate volume would be a graduated cylinder, since they are accurate within 1 percent. The best options are pipets, burets and volumetric flasks. All three are accurate within less than 0.2%.
Essentially, beakers are not precise, and therefore should not be used for measuring the volume of a liquid.
You decide to halve the time you spend in the shower each day and to turn off the water while you’re brushing your teeth and washing your face at the sink. Evaluate the effect that these actions might have onto different aspects of the water cycle if every person in your neighborhood also performed them.
Answer:
Decreasing the consumption of water helps to maintain the fresh waters of our planet, the less we consume the less quickly they will end.
If we abuse fresh water, one day the planet will end and the salt water from the seas will have to be filtered, which is much more expensive and more polluting.
Explanation:
In addition, we must bear in mind that the less we use the water, the less we will contaminate it with chemicals such as shampoos, rinse creams, soap, therefore less water will end up in the non-recyclable water cycle.
All the water we use will end up being polluted and will not enter the natural cycle of water from river rainfall, irrigation and evaporation in the skies.

Which type of cellular adaptation would create the greatest concern if found on a biopsy report? Dysplasia Metaplasia Hyperplasia Hypertrophy
Answer:
Dysplasia
Explanation:
Dysplasia has to do with the occurrence of abnormal growth of cells in tissues. In dysplasia, mature cells are replaced with less mature cells. These abnormal cells are referred to as dysplastic cells, and they have the potential of transforming to cancer cells. These are also referred to as preneoplastic lesions because in cancer development they precede neoplastic cells which cannot be reversed..
Metaplasia is the replacement of a well-differentiated (mature) with another mature cell. In cancer development, metaplasia precedes dysplasia.
Hypertrophy is the abnormal enlargement of tissues or organs as a result of the increase in the size of cells within the tissues or organs.
Hyperplasia is the abnormal enlargement of tissues or organs as a result of the increase in the number of cells within the tissues or organs.
Compared to others, Dysplasia has the greatest potential of becoming cancer; once dysplastic cells are formed it can easily morph to neoplastic cells which are cancer cells and that is why it will create the greatest concern if found on a biopsy report.

Which of the following relies on amolecule binding to the repressor to prevent the repressor from binding to the operator?
a. repression
b. gene expression
c. an operon
d. induction
Answer:
d. induction
Explanation:
A repressor is a protein capable of inhibiting target gene expression by binding to both operator sites and gene silencers. A DNA-binding repressor inhibits the interaction between the RNA polymerase and the DNA promoter sequence, thereby suppressing transcription into RNA. Moreover, the RNA-binding repressor is a protein that binds to the messenger RNA (mRNA) molecule in order to prevent its translation into protein. An inducer can start transcription by interacting with the repressor, thereby separating it from the DNA operator sequence.

Given the following DNA template, what is the appropriate mRNA strand
3' TACTTCAAACCGATT 5'
Answer:
5' AUGAAGUUUGGCUAA 3'
Explanation:
The process by which the information encoded in a DNA is used as a template to synthesize a mRNA is called TRANSCRIPTION. It is the first stage of gene expression carried out in the nucleus of eukaryotic cells and cytoplasm of prokaryotic cells by RNA polymerase enzyme.
The process of transcription follows the complementary base pairing rule, which says that Adenine base always hydrogen pairs with Thymine while Guanine pairs with Cytosine. During transcription, the Thymine base (T) is replaced by Uracil base (U). Hence, whenever RNA polymerase reads an A in the DNA, it synthesizes U in the mRNA and vice versa for T and A. The same applies for G and C.
For the DNA sequence;
3' TACTTCAAACCGATT 5'
The mRNA sequence will be synthesized;
5' AUGAAGUUUGGCUAA 3'

The mutation that causes SCD causes what kind of change in the structure of hemoglobin?
Answer:
A group of blood disorders generally passed on from the parents to the offspring is known as SCD or sickle cell disease. Of the disease, the most common is the SCA or sickle cell anemia. In the disease, the red blood cells comprise an abnormal form of the oxygen-carrying protein hemoglobin.
Generally, humans comprise hemoglobin A, A2, and F types. Of the three types, the hemoglobin F dominates till the age of 6 weeks, after which hemoglobin A dominates till the end of life. However, in the persons diagnosed with SCA, at least one of the beta-globin subunits in hemoglobin A gets substituted by a different form known as hemoglobin S. In the disease, a single nucleotide mutation in the beta-globin gene takes place, in this at 6th position, the glutamic acid gets replaced by Valine.

What type of weak bond occurs when atoms and molecules are temporarily attracted to each other by virtue of their proximity and
charge
The weak bonds that occur when atoms and molecules are temporarily attracted to each other by virtue of their proximity and charge are Vander Waal forces.
What are Vander Waal forces?Van der Waals forces are weak forces that keep electrically neutral molecules together. At some point, these molecules have an induced dipole, which means they have a partially positive and partially negative charge for a brief period of time, leading them to attract one other.
They are forces of Van de Waals: The movement of electrons causes dispersion forces between non-polar molecules (union between atoms of the same element or between atoms with very little electronegativity difference).
Therefore, Vander Waal forces are the weak bonds formed when atoms and molecules are temporarily attracted to each other due to their proximity and charge.
