When an enzymes breaks down or change shape
Answer:
An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support.

How does wood that is not burning differ from a nonflammable materials?
Wood is flammable, which means that it can burn when it is exposed to heat, oxygen, and an ignition source (such a spark or flame).
Thus, Nonflammable materials are those that do not readily ignite and do not burn even when exposed to high temperatures or flames.
Combustion Behaviour: During a fire, when wood is exposed to heat and oxygen, a combustion process takes place, releasing heat, light, and numerous combustion byproducts like carbon dioxide and water vapour.
The fire is maintained and can spread as a result of this procedure. Even when exposed to high heat or flames, nonflammable materials do not burn and do not support a fire.
Thus, Wood is flammable, which means that it can burn when it is exposed to heat, oxygen, and an ignition source (such a spark or flame).

what three patterns of biodiversity did darwin observe
Answer:
Species vary globally, species vary locally, and species vary over time.
Explanation:
Darwin noticed three distinctive patterns of biological diversity.
Charles Darwin observed three patterns of biodiversity during his exploration on the voyage of the HMS Beagle and in his subsequent research:
Species Variation: Darwin noticed that within a particular species, there is a wide range of variation among individuals.
Geographical Distribution: Darwin observed that different regions of the world have distinct sets of plant and animal species.
Fossil Record: Darwin studied the fossil record and recognized that it contains evidence of extinct species that differ from those currently living.
Thus, these three patterns of biodiversity species variation, geographical distribution, and the fossil record were instrumental in shaping Darwin's theory of evolution by natural selection.

Protein pumps are efficient because they
(Plz help)
In reference to the options listed in the image, we can say that protein pumps are efficient because they can move two types of molecules, which makes option B correct.
A protein pump is a kind of protein, often found in the cell membrane, that has the capability to pump specific substances in and out of the cell. Most of the processes that happen at the cellular level are naturally optimized for efficiency, even when the process consumes energy, as is the case with the protein pump.
The reason that the protein pump is considered efficient lies in how it uses the energy. Despite being an active process that consumes ATP to function, protein pumps are considered efficient because they can move two types of molecules at the same time, using the same molecule of ATP. This allows the cell to get more done for the same amount of energy.

What problems do animal cells have since they don't have cell walls?
Answer:
These antibiotics bond to protein molecules on the existing wall and prevent the cell from adding any new material as the wall stretches. When the cell wall stretches too far, it becomes weak and eventually bursts, destroying the cell. Since animal cells don't have cell walls, they are not affected by penicillin.

Answer:

Explanation:
which combination of cells and growth factors would serve as the control group?
Answer:
These stimuli, called growth factors, are naturally occurring proteins specific to certain groups of cells in the body. They include nerve growth factor, epidermal growth factor, and platelet-derived growth factor.
Explanation:
Hope this helps.
Growth factors are defined as the proteins that bind to specific receptors, which activate the cascade of signal transductions. The growth factors lead to proliferation, apoptosis, and development.
Different types of growth factors stimulating the signal transduction are:
1. Nerve growth factor is controlled by the gene NGF. It provides the instructions to make the beta protein, which is important for the survival and development of the nerve cell.
2. Epidermal Growth Factor is a type of factor that stimulates cell development and cell proliferation. It generally stimulates the fibroblasts and epithelial cells.
3. Platelet-derived growth factor regulates cell division and growth. These factors help in healing and repairing the wound and walls of the damaged blood vessels.
Thus, the growth factors when bound to specific cell receptors control the various activities of the cells.

The volume (V) of a cylinder can be determined by using the formula
V = ar?h,
where r = the radius of the base, and h = the height of the cylinder. What is the result
of solving this equation for r?
Answer:
Explanation:
To solve for r, simply means to isolate the variable:
[tex]V = pi*r^2*h\\[/tex]
The inverse of multiplication is division, so divide both sides by pi and h
[tex]\frac{V}{pi*h} = r^2[/tex]
[tex]r = \sqrt\frac{V}{pi*h}[/tex]

Blood is distributed from the surface of a bone to deeper central canals through channels known as Haversian canals.
What is Haversian canal?
Haversian canals are small channels that run through the bone tissue, and they serve as the highways for blood vessels, nerves, and lymphatic vessels. They distribute blood and other essential nutrients to the bone tissue and allow for the removal of waste products.
These canals are surrounded by concentric layers of bone matrix, known as lamellae, and they help to maintain the structural integrity of the bone. The distribution of blood through the Haversian canals is essential for the health and maintenance of the bone tissue.
