Which statement about biochemical reactions is false?
The statement that is false is that they can create new energy during the reaction. The correct option is a.
What is biochemical reaction?Biochemical reactions are chemical processes that occur in live cells to support life and promote cell growth.
To expedite most biochemical reactions, an enzyme is a type of biological catalyst.
The amount of activation energy required for the reaction to start is decreased by enzymes. Most enzymes are proteins that only interact with one particular chemical, known as their substrate.
The ratio of atoms in the reactants and products must always be balanced.
They have the capacity to store energy as a covalent bond. They have the ability to alter the cell's energy's shape. They follow the laws of physics and chemistry.
Thus, the correct option is a.

3) When two atoms bond chemically it is because of the interaction between
A) the nuclei of each atom.
B) the protons in each atoms.
C) all electrons in the atoms.
D) the valence electrons in each atom
Answer:
C - All electrons in the atoms
Explanation:
It depends on the bonding for an explanation.
If one atom is a metal and one is a non metal it will be ionic. This is because one atom transfers its electron to the other atom giving them both a charge. They will then be bonded due to opposite forces of attraction.
If both atoms are non metals it will be covalent. Electrons pair together in the center of two atoms that have merged together and they share their electrons.

What transformation takes place wen u light up a match
Answer:
Transformation that happens when you strike a match is from mechanical energy to thermal energy.
Explanation:
When you strike a match, it moves through the air until it rubs against a surface. The rubbing produces the heat required to light the match. (Thermal energy is heat energy)
Answer:
mechanical energy to thermal energy.
Explanation:
When the match is struck, it burns and the chemical energy in it produces heat energy and light energy
When you strike a match, it moves through the air until it rubs against a surface. The rubbing produces the heat required to light the match. This is a transformation from mechanical energy to thermal (heat) energy.

How many minutes are there in a 40-hour week?
A:2,000
B:2,400
C:1,400
D:1,200
There will be 2,400 minutes in a week of 40 hours. This can be calculated by the help of unit conversion of time. Thus, the correct option is B.
What is Unit conversion?
Unit conversion is the change of one form of unit to another form of unit of different system such as conversion of units of measurement of weight from gram to kilogram or milligram.
Unit conversion of one unit to another unit is used in order to have accuracy and avoiding the confusion in measurements. For example, the length of pencil is not measured in kilometers rather it is measured in centimeters or inches, which are comparatively smaller than kilometers. In such a case, one has to convert the unit of length from kilometer (km) to centimeter (cm).
The week of 40 hours can be converted into minutes by:
Number of minutes in 1 hour = 60
Therefore, the number of minutes in 40 hours = 60 × 40 = 2,400 minutes
Therefore, the correct option is B.

____________ diffuses out of the alveoli and into the pulmonary capillaries, while _______ diffuses out of the pulmonary capillaries and into the alveolar sacs.
Answer: Oxygen; Carbon Dioxide
Explanation:
Oxygen diffuses out of the alveoli and into the pulmonary capillaries, while carbon-dioxide diffuses out of the pulmonary capillaries and into the alveolar sacs.
What are pulmonary capillaries?PULMONARY CAPILLARIES: Deoxygenated blood enters into the pulmonary arteries from the right side of the heart and is delivered to the pulmonary capillaries, the smallest blood vessels inside of the lungs, attached to the walls of the alveoli.
Moreover, oxygenated blood then passes from the capillary beds through venules into the pulmonary veins. The pulmonary veins transport it to the left atrium of the heart.
Therefore, the pulmonary arteries are the only arteries that carry deoxygenated blood, and the pulmonary veins are the only veins that carry oxygenated blood.

Mendel was able to attribute the variation observed in the offspring of his experiment to the controlled fertilization process.
Mendel was able to control pollination and, thus, the fertilization process in the pea plants used for his experiment.
Mendel was able to effectively predict the outcome with self-pollination or cross-pollination with different results coming from each. Thus, he logically concluded that the variation observed in the offspring of his crosses is due to the fact that he controlled the fertilization process.

a bacterium is infected with an experimentally constructed bacteriophage
The complete question is:
a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have
A) T2 protein and T4 DNA
B) T2 protein and T2 DNA
C) a mixture of DNA and proteins of both phages.
D) T4 protein and T4 DNA
E) T4 protein and T2 DNA
A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.
A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.
The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria. Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.
In conclusion, The new phages produced would have D) T4 protein and T4 DNA.

What is the investment?An investment is a purchase undertaken with the hope of earning money or increasing capital. Appreciation is the term for an asset's value rising over time. When someone invests in a product, they do not aim to use it for immediate consumption but rather as a means of generating money in the future.
An investment always entails the use of some resource today, such as time, money, effort, or an item, with the hope of receiving a return that is higher than the initial investment. An investor might, for instance, purchase a financial asset right away in anticipation that it would generate income over the road or be able to be sold for a profit at a higher price.
Therefore, A bond was sold at its face value, while another was sold for less.
