Answer:
c
Explanation:
The statement which is not true about enzyme behavior is that all enzymes have an active site where substrates are temporarily bound.
Enzymes are proteins that can act as biological catalysts by increasing the rate of chemical reactions. The molecules upon which enzymes may act are known as substrates, and the enzyme which converts the substrates into different molecules are known as products. Almost all metabolic processes which take place in the cell need enzyme catalysis in order to occur at rates fast enough to sustain life.
Metabolic pathways depend upon the enzymes to catalyze individual steps. The study of enzymes is called as enzymology and the field of pseudoenzyme analysis recognizes that during evolution, some enzymes have lost the ability to carry out biological catalysis, which is often reflected in their amino acid sequences and thus have unusual 'pseudocatalytic' properties.
Thus, statement which is not true about enzyme behavior is C.

All members of a food web are equal in abundance and in their relative effects on one another.
It is false that all members of a food web are equal in abundance and in their relative effects on one another.
What is a food chain?A food chain is a network of links in a food web that runs in a straight line from producer organisms to apex predators, detritivores, or decomposer species. A food chain also demonstrates how organisms are connected to one another by the foods they consume. A food chain's levels correspond to several trophic levels. Producers are located on the first trophic level.
A food chain is created by the transfer of nutrients and energy from one creature to another at various trophic levels. Due to the fact that most species consume more than one kind of animal or plant, food chains locally entangle to form a food web.
It is false that all members of a food web are equal in abundance and in their relative effects on one another because A food web's constituents may have impacts that are out of proportion to their abundance. Therefore, it is false.

explain why is there no work in the following:
1. carrying a 15-kg backpack as you walk a horizontal distance of 50 m
2. pushing against a stationary wall for a long time
3.carrying a box inside a tricycle
Answer:
Explanation:
Well, this is one of those physics questions that relies heavily upon technicalities.
Something to remember is work is determined by force*distance.
1. When you are carrying a 15kg backpack, the weight or the backpack itself is quite indifferent. This is because the backpack is moving relative to you, so the backpack isn't doing diddly squat itself. The only force being exerted is yourself against the ground and vice versa because of gravity and Newton's Law, but when you have a horizontal distance (not vertical), the direction of your motion is 90 degrees to the exerted force. When you calculate this out using the formula and cos(90), you'll find the answer is technically 0.
If it were vertically, this'd be different.
2. Again, wording is important. Work is Force times DISTANCE. Key word in this situation, DISTANCE! When you push against a stationary wall (stationary as in, the wall "can do this all day" whereas you definitely can't), you're exerting a force against an object that really, really doesn't want to be moved. Walls in of themselves are MADE to not be moved, that's why they are walls. So, any force you exert is going to get multiplied by a distance of 0, and as we should know from basic times table charts, anything multiplied by 0 will ALWAYS be 0.
So, again, there's technically no WORK done, according to physics. Because again, work is a product of force and distance. So push harder, ya lazy good for nothin weakling!!
3. You can carry anything you want inside a vehicle, it doesn't mean there's any force being done. YOU'RE not doing squat, the vehicle itself is. In a tricycle, if the box is on the tricycle and not affecting you in any way, then there is no force being done despite an obviously moving distance.
By physics definition, there's EFFORT, but no WORK.

Cellular respiration moves carbon from atmosphere to geosphere. Thus option A and C are correct.
What is cellular respiration ?Cellular respiration can be defined as the process which occurs in every cells mainly mitochondria of plants and animals, it involve in the break down of sugars in the presence of oxygen and releases energy in the form of ATP.
The waste product of this process are carbon dioxide and water during exhalation process done by lungs, breathing and cellular respiration are related to each other.
At every step of cellular respiration energy is used in the form of ATP and carry out the normal function. It can aerobic and anaerobic respiration on the basis of use of oxygen.

A bus changes its velocity from 5 m/s to 15 m/s in 5 seconds. What is its acceleration?
A 2 m/s2
B 5 m/s2
C 25 m/s2
D) 75 m/s2
Answer:
[tex]\boxed {\boxed {\sf A. \ 2 \ m/s^2}}[/tex]
Explanation:
Acceleration is the rate of velocity's change with time.
We can calculate it by dividing the change in velocity over time.
[tex]a=\frac{v_f-v_i}{t}[/tex]
Let's define the variables. The final velocity is 15 meters per second. The initial velocity is 5 meters per second. The time is 5 seconds.
[tex]v_f= 15 \ m/s \\v_i= 5 \ m/s \\t= 5 \ s[/tex]
Substitute the values into the formula.
[tex]a=\frac{15 \ m/s- 5 \ m/s}{5 \ s }[/tex]
Solve the numerator first.
15 m/s - 5 m/s= 10 m/s[tex]a=\frac{10 \ m/s}{5 \ s}[/tex]
Divide.
[tex]a= 2 \ m/s/s = 2 \ m/s^2[/tex]
The acceleration of the bus is 2 meters per second squared.

Answer:
Ribosomes, cytoplasm.
Explanation:
Ribosomes are the organelle responsible for translation. Translation occurs in the cytoplasm.
The cytoplasm of a cell is at ph7 and the interior of an organelle is ph8
A. What is the quantitative relationship between the number of hydrogen ions present at pH 7 versus pH 8?
B. Using your knowledge of transport in cells, what is a possible mechanism for how the cytoplasm would have a lower pH than inside the organelle?
A pH=-log(10)[H+], from this formula we can deduct that when the number of protons is higher the pH is lower and when the number of protons is lower the pH is higher. This means there are more hydrogen ions in the cytoplasm compared to the inside of an organelle.
B Hydrogen ions are very small particles so they can easily diffuse through the plasma membrane inside the cytoplasm, resulting in a higher number of protons and a lower pH. Organelle membranes have a lower permeability for hydrogen protons so the pH is higher.
Can you use mass alone to predict whether an object will sink or float? Explain.
Answer:
No, you need both mass and volume to determine its desity to see if it can float.
Explanation:
Density is the only thing affecting whether something floats or sinks. If an object has a higher density than the fluid it is in (fluid can mean liquid or gas), it will sink. If it has a lower density, it will float. Density is determined by an object's mass and volume.
