Which statement best explains the importance of enzymes lowering the activation energy necessary for reactions to take place?
a Reactions that require less energy to begin are able to occur more quickly.
b Reactions produce heat, causing the chemical bonds to become strong.
c Reactions are able to proceed slowly to maintain the metabolism of the cells.
d Reactions requiring less energy are able to produce less product.

Answers

Answer 1

Answer:

A

Explanation:

because a enzyme simply speeds up a reaction and only does that by pressure and stress not by doing chemical changes

Answer 2

The statement which best explains the importance of enzymes lowering the activation energy necessary for chemical reactions to take place is: A. Reactions that require less energy to begin are able to occur more quickly.

A chemical reaction can be defined as a chemical process which mainly involves the continuous transformation or rearrangement of the ionic, atomic or molecular structure of a chemical element through a break down and formation of chemical bonds, in order to produce a new chemical compound.

As a general rule, the activation energy of a chemical reaction must first of all be reached by its combining chemical elements (reactants) before it can start or begin.

An enzyme can be defined as a biological catalyst that is used to speed up (increase) or catalyze (accelerate) the rate of a chemical reaction, by lowering (decreasing) the activation energy of its constituent chemical elements (reactants).

Hence, a chemical reaction that only require less energy to begin (start) are able to occur more quickly before those that require high energy.

In conclusion, the activation energy of a chemical reaction should be lowered in order for it to occur or take place fast (quickly) enough over a short period of time.

blood enters on the left side of the heart through the_____ and enters the left atrium. Then passes through the_____ to enter the left ventricle 

Answers

Blood enters on the left side of the heart through the pulmonary veins and enters the left atrium. Then passes to the mitral(bicuspid valve) to enter the left ventricle.

Blood is a fluid component of the circulatory system that is very vital for transporting oxygen and nutrients in the body system. It comprises cells suspended in plasma.

The correct answers for the blanks are:

Blank 1: Pulmonary veins

Blank 2: Bicuspid valve

The blanks can be explained as:

The left side of the heart has an atrium that gets the oxygenated blood from the lungs through the pulmonary veins.

Oxygenated blood from the left atrium flows to the left ventricle.

Blood from the left ventricle flows to the aorta that distributes the oxygenated blood to the body parts.

Cytokinesis, Mitosis, Interphase.

Cytokinesis, Interphase, Mitosis

Mitosis, Cytokinesis, Interphase

Interphase, Mitosis, Cytokinesis

Answers

Answer:

my best guess would be

Interphase, Mitosis, Cytokinesis

Explanation:

Interphase - stage where the cell prepares for Mitosis. During this stage the cell grows and replicates DNA.

Mitosis - part where the chromosomes are separated and are separated into 2 nuclei.

Cytokinesis - part where cells officially splits into two daughter cells.

Cell cycles are events that involve various series of steps for the cell to grow. It follows the order of interphase, mitosis, and cytokinesis. Thus, option D is correct.

What is the cell cycle?

The cell cycle is an important part of the growth and cell division of the eukaryotic cell. It includes interphase comprising the G₁, S (synthesis/replication), and G₂ phase, mitotic phase, followed by cytokinesis and G₀ phase.

The cell spends the majority of its time in interphase where the genetic material undergoes preparations and gets duplicated for the further process. In mitotic division the actual division of the organelles and the nucleic acid takes place.

Mitosis is followed by cytokinesis where the cytoplasm of the cell gets separated to form two daughter cells after the telophase stage. The cell then undergoes the G₀ phase which is the quiescent stage of the cell division where no cell division occurs.

Therefore, option D. interphase, mitosis, and cytokinesis are the correct order of the cell cycle.

A - luminosity
B - brightness
C - all of these
D - temperature

Answers

Answer:

option C. all of these.

Explanation:

The main sequence period is when a star will experience the majority of its life. Helium is currently being created via nuclear fusion from hydrogen. Thus, option C is correct.

What is a complete cycle of a particular star?

The main sequence phase, which our Sun is in, will be entered by the star if it is large enough to fuse hydrogen atoms into helium.

The mass of a star determines its life span. The life cycle of an object decreases with increasing mass.

The amount of substance present in a star's nebula, the enormous cloud of gas and dust from which it emerged, determines the star's mass.

The temperature and pressure rise when the material compresses, just as they do during formation. The freshly created heat briefly overcomes the effect of gravity, pushing the star's outer layers outward.

Therefore, As a star goes through this cycle their luminosity, brightness, temperature changes.
