How do molecules in the cells of the body release energy
Chemical energy is stored in the bonds of sugars. When the bonds of a sugar molecule are broken, a burst of energy is released that the cell can use. Cells can release energy in two basic processes: cellular respiration and fermentation.
Through the production of ATP, the energy which is derived from the breakdown of sugars and fats is redistributed in the cell as packets of chemical energy in a convenient form for use elsewhere.
How do cells release energy?All cells have energy to do work whereas glucose and other sugars have cell food. Almost all of these contain a source of energy for cell activities. When glucose is stored as glycogen or taken up as starch, it must be broken down into individual molecules before cells are able to to use it.
Chemical energy is stored in the bonds of sugars. When these bonds of a sugar molecule are broken, there is an explosion of energy which can be used by the cell.
These cells can release energy in two basic processes which are cellular respiration and fermentation. Oxygen is needed for cellular respiration, but not for fermentation. Furthermore, cellular respiration releases a lot of usable energy compared to fermentation.
Thus, through the production of ATP, the energy which is derived from the breakdown of sugars and fats is redistributed in the cell as packets of chemical energy in a convenient form for use elsewhere.

Does adding or taking away a proton change the identity of the element? Yes or no
Answer:
yes
Explanation:
The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.
Answer:
Yes
Explanation:
Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is!

2. Once the solution across a membrane does in fact reach equilibrium, the molecules in solution will
A. move across the membrane to the outside of the cell.
B. completely stop moving across the membrane.
C. continue to move across the membrane in both directions.
D. move across the membrane to the inside of the cell.
Answer:
B
Explanation:
Molecules and ions diffuse through cell membrane due to a concentration gradient. But, once the equilibrium is achieved between inside and outside the cell, molecules stop moving. Thus, option B is correct.
What is cell membrane?Cell membrane is an organelle surrounding the cell which facilitates the transportation of ions and molecules, inside and outside the cell. To maintain an ionic balance is important in metabolism of living things.
Ions such as sodium and potassium are balanced by a mechanism called sodium -potassium pump. The sodium ions outside the cell is greater than that of inside.
Similarly calcium pump works for calcium and magnesium. The concentration gradient of these ions make this flow of ions across cell membrane. Hence, once they achieve equilibrium the flow will stop and no ions will be transported across the membrane.

Amino acids have similar structures. What part of an amino acid's molecular formula distinguishes the macromolecule from other amino acids?
O the R-group
o the amino group
o the carboxyl group
O the nitrogenous base W
Answer:
The R-group
Explanation:
Amino acids are organic compounds that combine to form proteins. There are 20 of them, out of which 9 are essential. All of them have a similar structure: they consist of an alpha (α) carbon atom bonded to an amino group (NH2), a carboxyl group (COOH), a hydrogen atom, and an R group. The R group is the organic component, a side chain, that is unique to each amino acid.
This is why the first option is the correct one.
Answer:
the R-group
Explanation:

Two students were having a discussion about viruses.
Student A believes viruses are not living organisms .
Student B believes viruses are living organisms.
Which student is correct and why?
Student A is RIGHT because viruses are not living organisms.
All living organisms are composed of cells, and viruses do not have cells (they only have protein coats that protect their genetic material).Viruses are entities that need to parasite the cells of different host organisms to survive.In consequence, a virus cannot replicate in absence of a suitable host cell.In conclusion, student A is RIGHT because viruses are not living organisms.

Place in order the correct sequence by which water flows through plants
1. transpiration from the leaves
2. absorption from the soil by root hairs
3. movement from roots to stem
4. flow upwards in the stem
Answer:
The correct sequence is - 2, 3, 4, 1.
Explanation:
The movement of the water takes place in the plant from the soil and moves up to leaves and from there to the atmosphere. Root hairs help in the absorption of the water from the soil with help of the epidermis of root hairs. Water then takes the path from the root to the stem with help of cortical cells.
Once the water reaches the endodermis or endodermal cell the water freely flow in the xylem cell upwards the stem moves to leaves by the transpiration stream. In the process of transpiration, an excess amount of water evaporates into the atmosphere.
