Answer 1

Answer:

a} Allosteric regulation is just any form of regulation where the regulatory molecule (an activator or inhibitor) binds to an enzyme someplace other than the active site.The shape of the active site is changed, allowing substrate to bind at a higher affinity.

b) The molecules that bind cellular respiration enzymes act as signals, giving the enzyme information about the cell's energy state. ATP, ADP, and NADH are examples of molecules that regulate cellular respiration enzymes. ATP, for instance, is a "stop" signal: high levels mean that the cell has enough ATP and does not need to make more through cellular respiration.

c) This is a case of feedback inhibition i in which a product feeds back to shut down its pathways.

Each year, the United States' federal costs exceed the anticipated national budget. In fact the last time that the United States government was able to end a fiscal year without accruing more debt was in 1960. This means that due to excessive spending and compounding interest accrued, the United States' national debt has escalated astronomically over the past several decades. The table shown below lists the recorded U.S. national debt amounts, written in standard form, for each decade, from 1960 to the year 2010.


Year U.S. national debt (in U.S. dollars)

1960 $286,330,760,848.37

1970 $370,918,706,949.93

1990 $3,233,313,451,777.25

2000 $5,674,178,209,886.86

2010 $13,561,623,030,891.79

For each decade, convert the U.S. national debt amount to a number in scientific notation, rounded to the nearest hundred millions dollars. Enter in numerical answers only.

Ashes (which are made of carbon), carbon dioxide gas, water vapor, heat, and light are produced when wood is burned. Since this change cannot be undone, it is a chemical change. Since oxygen and hydrogen unite to create a single product, Thus option D and E is correct.

What is chemical changes?

A chemical change is the transformation of one substance into another, the emergence of new compounds with distinct properties, or any combination of these.

It happens when two compounds mixes to create a new material (synthesis or either decomposes to form more substances).

Chemical synthesis, or, alternatively, chemical breakdown into two or more separate molecules, occurs when one material reacts with another to create a new substance.

These processes are referred to as chemical reactions, and they are typically irreversible barring additional chemical reactions.

Therefore, burning of wooden logs and formation of water is an example of chemical changes.

Answers

Answer:

Carbon cycle is very important for the plants and animals that are divided into 4 steps and these steps are:

1.The carbon enters the atmosphere in the form of carbon dioxide.Example: respiration and combustion.

2.The carbon dioxide present in the environment is used by the plants and  plants expel oxygen after the process of photosynthesis.

3. Animals present in the environment eat the plants and pass on the carbon in the food chain. They exhale carbon dioxide into the environment.The plants and the animals die after a certain period of time.

4. The body of plants and animals is consumed by decomposes and the carbon is returned into the atmosphere in the form of carbon dioxide else fossils of plants and animals are formed which contains carbon.

A student wants to investigate the force of gravity. The student has an apple and a marble. What would be the best way for the student to use these materials? Place the apple on the floor. Roll the marble so it hits the apple. Put both objects on a desk. Push them forward at the same time. Hold both objects at the same height above the floor. Drop them at the same time. Place the marble on a desk. Place the apple next to the marble so the objects touch.

Answers

Answer:

Put both objects on a desk

Explanation:

The best way to use the materials to investigate the force of gravity would be to put both objects on a desk. The force of gravity can thus be obtained by measuring the distance between the objects as well as their masses.

According to Newton's law of universal gravitation, the force of gravity (F) between two objects is directly proportional to the product of their masses (m and M) and inversely proportional to the square of the distance (d) separating them.

Mathematically,

     F = G [tex]\frac{mM}{d^2}[/tex] where G is a constant.

Explanation:

Independent variable in an experiment refers to the variable which the experimenter changes or manipulates in order to bring about a measurable response. In this case, the independent variable is the TYPE OF BATTERY USED.

Dependent variable is the variable that responds to changes made to the independent variable. It is the measured variable in an experiment. In this case, the dependent variable is the TIME THE CLOCK STOPPED FOR EACH BATTERY

Control is the group that does not receive the experimental treatment. In this case, NO control group is USED.

Constant is the variable that the experimenter keeps unchanged throughout the experiment for all groups. The constant in this experiment is the CLOCK USED.

(3) This kind of vacation, one where the traveler pays her own way and volunteers her time and efforts while on the trip, is beingembraced by people all over the world.

(12) There is almost no limit to where adventurers can go.(13) Perhaps the most compelling reason to consider a volunteer vacation is the feeling of intrinsic happiness and satisfaction of doing important, helpful work. (14)Even if a volunteer cannot stay in the location long enough to see a project to its completion, just knowing that ones work has helped people in need, brought vitalresources to folks who needed it, or helped to save endangered plants or animals brings a kind of pride and sense of meaning that simply spending money to lie by apool could never deliver.

(17) Because the whole goal behind a vacation is to escape ones usual, familiar surroundings and refuel, volunteer vacations seem like a win-winsituation with a promise of some kind of success for both the volunteer and those helped by the work.
