Answer: Electrolytes are minerals in your body that have an electric charge. They are in your blood, urine, tissues, and other body fluids. Electrolytes are important because they help Balance the amount of water in your body.Balance your body's acid/base (pH) level .Move nutrients into your cells, Move wastes out of your cells, Make sure that your nerves, muscles, the heart, and the brain work the way they should. Sodium, calcium, potassium, chloride, phosphate, and magnesium are all electrolytes. You get them from the foods you eat and the fluids you drink. The levels of electrolytes in your body can become too low or too high. This can happen when the amount of water in your body changes. The amount of water that you take in should equal the amount you lose. If something upsets this balance, you may have too little water (dehydration) or too much water (overhydration). Some medicines, vomiting, diarrhea, sweating, and liver or kidney problems can all upset your water balance. Treatment helps you to manage the imbalance. It also involves identifying and treating what caused the imbalance.

Explanation:
A plasmid that encodes resistance to ampicillin and tetracycline is digested with the restriction enzyme PstI, which cuts the plasmid at a single site in the ampicillin-resistance gene. The DNA is then annealed with a PstI digest of human DNA, ligated, and used to transform E. coli cells. (a) What antibiotic would you put in an agar plate to ensure that the cells of a bacterial colony contain the plasmid
Answer:
tetracycline
Explanation:
When the DNA insert is ligated in Pstl site, the ampicillin gene is disrupted while tetracycline gene is still intact.
- If the bacterial colony is growth in a medium with only ampicillin, only the cells that contains the plasmid with the insert will grow.
- If the bacterial colony is growth in a medium with only tetracycline, the cells which have incorporated the plasmid will survive. We cannot distinguish between cells with plasmid + insert and plasmid alone.
- If the bacterial colony is growth in a plate with ampicillin + tetracyclin, only the cells with the plasmid without the insert will grow.
Therefore, to ensure that the cells of a bacterial colony contains the plasmid, they have to be seeded in a plate with tetracycline.
Which characteristic of viruses prevents them from being used as evidence to support cell theory?

Answer:
Viruses replicate only inside host cells.
Explanation:
Viruses are not used as evidence to support the cell theory because they are not considered a cell and cannot carry out vital life processes without getting into host cells.
According to the cell theory, the cell is the basic unit of life, all living organisms are made up of cells and cells arose from preexisting cells. A virus that is not in a host cell is just a piece of DNA/RNA surrounded by a protein coat and is not capable of carrying out any life process for it to be considered living.
Viruses are only able to reproduce and multiply when they get access to a living host. They use the genetic mechanisms of the host to replicate their DNA/RNA using the lytic or lysogenic cycle. Hence, they are not used to support the cell theory.

Which of the following factors most likely triggers arousal from hibernation?
A) the sun rising in the morning B)snow falling onto the ground
C) the environmental temperature dropping below 0 °C
D) a significant decrease in the animal's respiration rate
Answer:
A) the sun rising in the morning
Explanation:
In biology, hibernation refers to a physiological state where a plant or animal is metabolically inactive in the winter period (characterized by extreme cold). As far as the animal or plant is concerned, the cold weather during winter is an adverse condition, hence, they undergo hibernation in order to conserve their energy.
According to this question, arousal or wakening from hibernation would be triggered in the presence of heat source, which in this case is the SUN RISING IN THE MORNING.
Under which condition is the speed of cellular chemical reactions within a cell most likely to decrease?
Answer:
The products of the reaction decreases
Explanation:
When the product are formed in a chemical reaction it leads to decrease in chemical reaction rate in a cell.
What Factors Affect the Speed of Chemical Reactions?Some chemical reactions are fast and some are slow due to presence of different factors.
The collision between the reactants specially at the reactive site of the molecule will be needed to complete the chemical reaction.
So larger the size of reactant slower be the reaction or even no reaction occur due to less collision.
The more surface area of the particle lead to more collision and faster the reaction.
More Concentration of chemical reactants lead to faster the reaction rate. Higher the pressure of the reactant lead to faster the reaction rate.
Increasing in temperature can also lead the molecules move faster, average kinetic energy of the molecule can also increases.

Which activity causes the least amount of wetland and estuary degradation when it occurs near the coast?
A. dune grass rehabilitation
B. hydrologic alterations
C. agricultural development
D. urbanization and land development
Answer:
The activity which causes the least amount of wetland and estuary degradation when it occurs near the coast is:
A. dune grass rehabilitation
Explanation:
This is actually a rehabilitation effort, unlike the other three options that cause land degradation. A dune grass rehabilitation accretes sand and minimizes the rates of beach erosion. The program tries to protect coastal infrastructure and upland properties from storm damage by planting vegetation, fencing off sensitive areas, blocking storm surge, creating dune walkways, and absorbing wave energy. During dune grass rehabilitation, activities that adversely affect the dunes are avoided.

Explanation:
Climate is a significant ecological impact on environments. Changing Climate influences biological systems in an variety of ways. For example, warming may constrain species to relocate to higher scopes or higher rises where temperatures are more helpful for their endurance.
Environmental change not just influences biological systems and species straightforwardly, it likewise communicates with other human stressors, for example, advancement. Although a few stressors cause just minor effects when acting alone, their combined effect may prompt emotional natural changes. For example, environmental change may worsen the pressure that land improvement puts on delicate water front zones. Also, as of late logged forested zones may get defenseless against disintegration if environmental change prompts increments in substantial down pour storms.

What type of variation is nessary for natural selection to occur
Answer:
Genetic variation
Explanation:
Genetic variability (diversity) stems from two basic processes: mutation and recombination.
If there were no mutations, all genes would exist in only one form, they would not have alternative forms.
Since phenotypic variability also depends on genetic variability, it is clear that the processes of mutation and recombination contribute to the creation of a large number of different phenotypes.
In Leonardo da Vinci’s time, nobody knew that the arteries were joined to the veins by tiny, invisible capillaries. This means that even though he studied the heart in detail, he thought that the arteries and veins were dead ends. Why did this make it difficult for him to understand how the heart worked?
Answer:
It was difficult for him to understand how the heart worked because he wasn't fully aware of the pumping mechanism of the heart and how the circulation of blood goes inside the body. Not seeing the capillaries meant that the heart pumped blood towards the vessels and into a dead end. He couldn't understand where the blood that was being pumped goes to.
Explanation:
Leonardo da Vinci is considered one of the earliest persons to study the heart. Although he made an exceptional observation of the different parts of the heart, he couldn't track the capillaries. He didn't know that these tiny structures connected the arteries and the veins. He believed that the heart was meant to transfer heat from the liver going to the muscles. He also believed that the lungs helped cool the blood.

The correct sequence for the general adaptation syndrome is:_________
a) Exhaustion phase, alarm phase and resistance phase
b) Alarm phase, resistance phase and exhaustion phase
c) Resistance phase, exhaustion phase and alarm phase
d) Alarm phase, exhaustion phase and resistance phase
Answer:
The correct sequence for the general adaptation syndrome is: b) Alarm phase, resistance phase and exhaustion phase
Explanation:
The general adaptation syndrome describes what happens to our body when it is under stress.
The first phase is the Alarm phase. In this stage, the body activates the fight or flight response, causing an increase in adrenaline and cortisol, blood pressure, respiratory frequency, amongst other things that prepare us to react in a situation that we perceive as dangerous.
The second phase is the resistance one. During this phase, the body undergoes a different process that adapts it to manage the stress, with an elevated amount of cortisol and blood pressure.
The third phase is the exhaustion phase. If the stress levels continue to be high, the body passes to this stage. The body is exhausted and cannot keep dealing with stress, which causes mental and physical problems such as anxiety, depression, fatigue, stress-related illnesses, among other symptoms.
