Answer:
True
Explanation:
Moving a book so the potential energy of the system decreases is a true statement.
What is potential energy?A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.
A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.
Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.
Therefore moving the book to a lower shell change potential energy, which decreases.

Scientists who study this disease using a bacterium known as Paracoccus denitrificans. Scientists were able to produce the same change in the bacterium’s genes that they found in the mitochondria of their human patients.
What is the BEST explanation for why scientists can use a bacterium to study this human disease?
A
Bacterial genes are very similar in structure to human genes.
B
Bacteria can be used as a model to study more complex cells.
C
The genes and chemical pathways found in bacteria are similar to those in human mitochondria.

this situation, a plant's response system is working in conjunction with the —
immune system.
vascular system.
reproductive system.
root system.
Answer:
B
Explanation:
In this situation, a plant's response system is working in conjunction with the vascular system. Therefore, option B is correct.
What is a vascular system?The complex network of conducting tissues known as the plant vascular system connects all organs and carries water, nutrients, organic compounds, and different signaling molecules throughout the body of the plant. The primary transport systems of plants, xylem and phloem, make up vascular tissue. They often coexist in vascular bundles that cross the roots, stems, and leaves of all plant organs. Water and dissolved ions are moved upward through the plant through the xylem, starting at the roots.
Clubmosses, horsetails, ferns, gymnosperms (including conifers), and angiosperms are examples of vascular plants (flowering plants). The group is known by its scientific names, Tracheophyta, and Tracheobionta.

Answer:
focusing on a single task is the best strategy for change
Explanation:
The career of Jacques Cousteau illustrates that focusing on a single task in life is the best strategy for the change in the social life of an individual as well as in the society. If a person performs many activities at the same time so its focus and concentration divides over the activities which is not more advantageous as compared to that person who focus on the single task until it is completed so focus on the single task in life is necessary for producing big change in life and in the society.

Use the same article to answer the following questions. Muscle Contraction What happens if there is not enough ATP available?
If there is not enough of ATP molecules available then, there is no muscle contraction.
What is Muscle contraction?Adenosine triphosphate (ATP) is a way to store and also uses this energy in the breaking down the complex compounds which are present in the food that we eat. If there is not enough amount of ATP present, then this could lead to a lesser oxygen available in the cell on the food being eaten. Hence, this will affect the energy that we can get from a certain type of food particles.
Muscle contraction is the process of tightening, shortening, or lengthening of the muscles when a person do some type of activity. Muscle contraction can happen when a person can hold or pick up something, or when a person can stretch or exercise with weights.
