Heat, acids, bases, salts, or mechanical agitation can unfold, change the shape or ________ proteins but none of these factors changes the primary structure of the protein.
Heat, acids, bases, salts, or mechanical agitation can unfold, change the shape or denature proteins.
What is Denaturation?This is common in protein molecules and it involves the breaking of the weak bonds which ensure that the protein's arrangement is highly ordered.
Heat and other chemicals are able to denature protein which is why it was chosen as the most appropriate choice.

Which process occurs when two haploid (N) nuclei fuse and a single diploid (2N)
nucleus is formed?
implantation
mitosis
fertilization
meiosis
Answer:
c. fertilization
Explanation:
Fertilization is the process when two haploid (N) nuclei fuse and a single diploid (2N) nucleus is formed. Therefore, option C is correct.
What is fertilization?Fertilization is the process by which a sperm cell from a male fuses with an egg cell from a female to form a zygote. In most organisms, including humans, fertilization occurs during sexual reproduction.
The zygote contains a unique combination of genetic information from both the mother and the father and will develop into an embryo, which will eventually grow into a fetus. Fertilization is a critical step in sexual reproduction, as it initiates the development of a new organism with its own unique set of genetic characteristics.
Thus, fertilization is the process when two haploid (N) nuclei fuse and a single diploid (2N) nucleus is formed. Therefore, option C is correct.

Answer:All star smash mouth
Explanation:
All star smash mouth. A planet is a sizable body that revolves around a star.
What are planets?
An object must have enough mass to have been compressed by gravity into a spherical, or round, shape in order to qualify as a planet. It must also be big enough for any rocky or icy debris in its orbit around the star to have been swept away by gravity.
According to science, planets start to form when a nebula, or dense cloud of gas and dust, revolves around a young star.
Gravity forces the nebula's material fragments to clump together over time. These aggregates develop and gather over time. These clusters eventually develop into planets.
Therefore, All star smash mouth. A planet is a sizable body that revolves around a star.

Oxygen is essential for many forms of life, yet early earth had very little oxygen in the atmosphere. Where did the increase in oxygen come from?.
Answer:
Literally, it is the waste product of cyanobacteria, also known as blue-green algae.
EXPLANATION
Explanation:
Between two to three billion years ago, Earth's atmosphere started changing.
Organisms living then were doing so anaerobically (without oxygen), but there was a gradual build up of oxygen in the atmosphere - the reason for this, as well as for the percentage of oxygen stabilising at around 21% is still unclear.
What we do know is that tiny organisms known as cyanobacteria (or blue-green algae) would photosynthesise carbohydrates for their nutrition and growth using sunlight, water, and carbon dioxide.
The waste product of photosynthesis, till today, is oxygen.
Over time, this oxygen increased till it reached the levels that we experience today.
The chloroplasts in today's plants are symbiotic cyanobacteria that continue the same process started billions of years ago.
What is the name given to the
final stage of cellular respiration?
A. Glycolysis
B. ADP
C. The Electron Transport Chain
Answer:
B
Explanation:
the others don't match.
"Oxidative phosphorylation is the final stage of aerobic cellular respiration. There are two substages of oxidative phosphorylation, Electron transport chain and Chemiosmosis. In these stages, energy from NADH and FADH2, which result from the previous stages of cellular respiration, is used to create ATP."
