A. number of atoms
B. chemical bonds
C. total mass
D. total energy
Answer:
I think it's chemical bonds I'm not of that helped
The changes occurs in chemical bond during a chemical reaction between two compounds. The correct option is B.
What is chemical bond?A chemical bond is a long-lasting point of attraction among atoms, ions, or molecules which then allows chemical compounds to form.
Ionic bonds are formed by the electrostatic force between oppositely charged ions, whereas covalent bonds are formed by the sharing of electrons.
A covalent bond is the strongest bond in chemistry. In such bonding, each atom shares electrons that bind them together.
The bonds that hold molecules together break apart and form new bonds during chemical reactions, rearranging atoms into different substances.
Each bond requires a different amount of energy to break or form; without this energy, the reaction cannot occur, and the reactants remain unchanged.
Thus, the correct option is B.

When you stop growing, your cells stop dividing.
True
False
Help please
Answer:
Absolutely not mitosis and meiosis don't stop until your heart stops beating.
It is false that When you stop growing, your cells stop dividing.
When you stop growing, it does not mean that all your cells stop dividing. In fact, cells in the human body continue to divide and replenish throughout life, albeit at different rates depending on the type of cell.
The human body is composed of various cell types that have different lifespans and rates of cell division. For example, cells in the skin, gastrointestinal lining, and blood undergo continuous division and turnover to replace old or damaged cells. These tissues are constantly renewing themselves.
However, some cells, such as neurons in the brain and muscle cells, have limited or no capacity for cell division after a certain stage of development. These cells primarily grow in size rather than dividing to create new cells. Therefore, not all cells in the body continue to divide once growth stops.

Einstein's theory of general relativity was published in 1916. It became fully
accepted by scientists in the 1960s and is currently the best explanation of
gravity. Why did it take so long to become an accepted scientific theory?
A. The scientific community requires a certain amount of time before
a theory can be accepted.
B. Einstein's theory was difficult for many people to understand.
C. More evidence needed to be gathered to validate the ideas in the
theory
D. No scientific laws could be found to validate the theory.
SUBMIT
Answer:
B. Einstein's theory was difficult for many people to understand.
Explanation:
Einstein’s theory of general Relativity was largely Ignored for three decades because scientists at the time thought the theory was too complex compared to Newton's.
Therefore, it took long before the general science community accepted Einstein's theory of general relativity because Einstein's theory was difficult for many people to understand.
"B. Einstein's theory was difficult for many people to understand."
D. More evidence needed to be gathered to validate the ideas in the theory.
when muscles contract, the ____ energy of ATP is used to drive the ____ energy of contraction
Answer:
1. Chemical energy
2. Mechanical (kinetic) energy
Explanation:
The contraction of our muscles is accompanied by movement. Contraction of muscles involves the proteins myosin and actin, which forms a cross-bridge. Calcium ions bind to troponin protein allowing the myosin to bind to the binding sites on the actin protein.
However, for this cross-bridge cycle between myosin and actin to occur repeatedly, ATP is needed to induce the release of the myosin from the actin active site. Therefore, When muscles contract, the CHEMICAL energy of ATP is used to drive the MECHANICAL energy (kinetic energy) of contraction.
NOTE: ATP supplies chemical energy to induce movement of muscles during contraction. Energy due to motion is called KINETIC ENERGY.
When muscles contract, the Chemical energy of ATP is used to drive the Kinetic energy of contraction ; The missing answers are ; Chemical and Kinetic
When we contrast our muscles ATP induces the release of myosin from its actin active site ( i.e. the use of the chemical energy contained in ATP ). the release of myosin leads to the contraction of the muscles, which is a form of mechanical/kinetic energy. The proteins involved in the contraction ( kinetic energy ) of muscles are myosin and actin while the calcium ion involved is troponin.
Hence we can conclude that When muscles contract, the Chemical energy of ATP is used to drive the Kinetic energy of contraction.

4) Cell C suddenly lost all its dynamin proteins. Which of the following will most likely happen
right
away as a result of this loss?
A) Transcription factor X will no longer be able to go to the nucleus
B) A vesicle bud will no longer be pinched off from a membrane
C) A vesicle will no longer be tethered to a target membrane
D) A protein will no longer be targeted to the mitochondrial matrix
E) Two of the above
Answer:
B) A vesicle bud will no longer be pinched off from a membrane
Explanation:
Dynamin is a protein responsible for endocytosis, the process where the cell takes substances in from outside the cell through a system of vesicles. At the edge of the cell, the membrane pinches in to form a vesicle, which buds off from the membrane and enters the cell.
The step of this process that dynamin is involved in is in cleaving newly formed vesicles from the membrane. Without it, a vesicle bud will no longer be pinched off from a membrane

General intelligence, commonly referred to as the “g factor,” is a wide mental capacity that affects how well on cognitive ability tests a person does. Thus, option B is correct.
What is general intelligence?It is possible to describe general intelligence as a construct made up of various cognitive skills. These skills enable people to learn new things and resolve issues.
Underlying specialized mental talents in domains like verbal, spatial, numerical, mechanical, and mechanical abilities is this general mental capacity.
It is hypothesized that general intelligence influences how well people perform on all cognitive tasks.
You can relate general intellect to athletic ability. A person may be an exceptional runner, but this does not automatically make them a great figure skater.
Therefore, Dr. Ron supports the notion of general intelligence.

Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because:
a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.
Answer:
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
Explanation:
Photosynthesis is the means by which green plants produce their foods by the use of sunlight, chlorophyll and carbon dioxide.
During the day, the grape make use of the process, photosynthesis, to get its sufficient food, thus the reason for the slight shrink. But at night, it respire well and new cells are produced. So that its size increase a bit.
