Answer:
Tube 3
Explanation:
Pancreatic amylase's optimum pH is basic, NaHCO3 is a base so it will provide the optimum pH for the enzyme to catalyse the breakdown of starch.
In tube 1 there will not be the breakdown of starch as there simply isn't any enzyme to break it down.
In Tube 2, the enzyme pancreatic amylase will most probably become denatured (loss of shape), as HCl is acidic which causes it to lose shape causing a change in the active site and will never be able to catalyse the breakdown of starch.
Hope this helps :)

A paper mill located on a coastal region of Florida experienced an accident in which a large portion of toxic waste from the plant leaked into the ocean. This waste contained dioxins which affect animal health and the environment. The company cleans up the waste and the state requires that they hire an ecologist for the next 10 years to monitor the area.
Which statement best explains why the state required the company to hire an ecologist?
Group of answer choices
The state wants to be sure there are not new, mutated species.
The state needs to ensure the company spent enough money restoring the ecosystem.
The state wants to see if the spill will have a continued impact on biodiversity.
The state needs to be sure the company will not be sued by an environmental agency.

The given question provided the data of an experiment to determine the effect of water temperature on the amount of sugar that dissolves in a beaker of water and asked to identify the components:
Amount of Water (mL) - constantThe temperature of Amount of Sugar - constantThe Temperature of water (°C) - variableAmount of Sugar dissolved (g) - variableIn any research investigation or experiment, there are three main parts that are:
Independent variable: These are the variables that are manipulated or change to see the effect on the dependent variable, these are manipulated by the researcher. In this investigation, the independent variable is the temperature of the water as it affects the amount of sugar that dissolves.Dependent variables: these are the variable that also changes due to change and according to the change in the independent variables. In this investigation, the amount of sugar that dissolves changes according to the change in the temperature of the water, thus, its dependent variable.Constant or control: these are the parts that do not change during the experiment so there is no other influence occur in the Dependent variable.Thus, the correct answer is -
Amount of Water (mL) - constantThe temperature of Amount of Sugar - constantThe Temperature of water (°C) - variableAmount of Sugar dissolved (g) - variableLearn more about independent variables:

While volunteering at a hospital, Alex learns that there are several different human blood types and they are determined by alleles. For example, a person with an allele for type A blood and an allele for type B blood will have type AB blood. Alex asks a nurse if blood type A or B is dominant. What answer does the nurse give him?
Answer:
They are codominant
Explanation:
There are 3 different alleles: IA, IB and i - IA and IB are codominants, i is recessive. Codominance means neither allele can mask the expression of the other and both alleles A and B are expressed in the blood type.
Blood type A and Blood type B both are dominant if allele A or allele B present with the O allele, however, they show codominance if they present together.
The human blood group system is known as the ABO blood group system that exhibits codominance. Following are the characteristics of this blood group system:
The system consists of three alleles A, B, and O.Both A and B are dominant in relation to O, and therefore blood group A or B can have the genotype AA or AO or BB or BO respectively.If both A and B are present together then they show codominance and have the genotype AB.Thus, the correct answer would be - both A and B are dominant if allele A or allele B present with the O allele, however, they show codominance if they present together.

Work backwards: if you find an offspring that is not genetically identical to its parent's organism, what type of reproduction created it? why?
Answer:
The organism was created via sexual reproduction.
Explanation:
If it were genetically identical to its parent, then that would've meant that it was created asexually. In sexual reproduction, the offspring's DNA is more or less a combination of both parents' DNA.

Using your knowledge of the water cycle, why do you think high sea surface
temperatures correlate to a large amount of water vapor in the atmosphere?
Answer:
Explanation:
The correlation between sea surface temperature and water vapor is that both are driven by seasonal changes. They both increase in the hemisphere during summer. Seasonal changes in water vapor are, however, more evident across the land, largely due to changes in land surface temperature.

Why do you think matter changes its form based on temperature? In science explain
Answer:
Look down to the explanation
Explanation:
Because matter is extrinsic property ( meaning it could be changed based on the enviornment), things like pressure and temperature can affect the state and form of matter. "When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation)." So if the temperature is increased, it is the cause of thermal/heat energy, and this is what makes solids into liquids, liquids to gasses, and gasses to plasma (including other additional states.

Birds have air sacs and lungs. When birds
breathe (in / out,) oxygen-rich air fills the
lungs and air sacs. When birds breathe
(in / out), the oxygen-poor air leaves the
lungs, and stored fresh air enters the lungs from
the air sacs. This means that birds always have a
supply of oxygen-(rich / poor) air.
How is DNA created?(short answer)
Explanation:
For a strand of DNA to form, nucleotides must be linked into chains, with the sugar phosphate groups alternating. DNA is made of the building block chemical called nucleotides.

How much more kinetic energy does your car have when it changes its speed from 16 km per hour to 80 km per hour
Answer:
The correct answer would be - 25 times more.
Explanation:
The kinetic energy of a moving object increases with the increase in the speed of the object. It is evident that the kinetic energy of a moving object increases as the square of its velocity or speed. It means if a car moves with the speed of 32 km/hr has four times as much kinetic energy as the car moving with 16 km/hr.
Similarly, if a car changes its speed from 16 to 80 km/hr the kinetic energy will be -
= (80/16)^2
= (5)^2
= 25 times more.
Thus, the correct answer would be - 25 times.
The correct answer would be - 25 times more.
