Answer:
2.) However, after a certain temperature (about 45°C) the bonds within the enzyme molecule that keep its shape, begin to vibrate so violently that they break. This results in the enzyme losing its shape, including the active site's shape. This is called denaturation. As the substrate can no longer fit into the active site, the activity of the enzyme dramatically decreases. Once all the enzyme molecules are denatured, the enzyme activity will completely cease.
Explanation:
Enzymes are organic catalysts which speed up the rate of chemical reactions. Since most enzymes are proteins, they have specific structures which relates to their catalytic abilities.
When heat above the optimal temperature of activity (about 45°C and above) is applied to an enzyme, the structural integrity of the enzyme molecules are compromised. The various quaternary, tertiary, secondary and structures of the protein are destroyed. This also results in the shape of the active site of the enzyme to be distorted. As a result, substrate cannot bind and the enzyme loses its activity.

Cellular respiration produces
A. ATP.
B. Oxygen
C. cellulose
D. glucose
Answer:
ATP
Explanation:
Carbon dioxide is transported from your mitochondria out of your cell, to your red blood cells, and back to your lungs to be exhaled. ATP is generated in the process.
Cellular respiration produces ATP. Thus, option A is correct.
what is cellular respiration?The process in which conversion sugars into energy (ATP) occur by cells called as cellular respiration. It can be used by a number of cellular components as a source of energy.
There are two types of respiration occur such as aerobic and anaerobic respiration.
Aerobic respiration occur in presence of oxygen which act as a powerful electron acceptor, mostly seen in eukaryotes.
In case of prokaryotic organisms such as bacteria and archaebacteria, other types of respiration occur.
Carbon dioxide is also a product of cellular respiration which is released as a waste product.
There are three major types of cellular respiration occur such as aerobic, lactic acid fermentation, alcoholic fermentation.
In aerobic respiration 36 ATP, where as in lactic acid fermentation 2 ATP and alcoholic fermentation 2 ATP are produced.

name the things which help in the preparation of carbohydrates in plants
Answer:
People breathe oxygen in and carbon dioxide out, but for a plant to make carbohydrates, the leaves take in carbon dioxide through the stomata on the leaf surfaces. From the stomata, the mesophyll cells use the carbon dioxide to combine it with water and light for photosynthesis.
Suppose insects that feed on the plants were placed inside the growth chamber as well. Predict how this might affect the levels of CO2 in the growth chamber. How does this model, on a smaller scale, represent the cycling of carbon through Earth's systems?
Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the diagram illustrating the growth chamber. However, since insects also produce/exhale carbon dioxide (CO₂) as a waste product, the level of CO₂ in the growth chamber will increase since insects will serve as an additional source for the production of CO₂.
This model shows how carbon is been cycled though the earth's systems. The CO₂ released/exhaled by animals is been inhaled by plants and used for the production of food substance like glucose (through the process of photosynthesis). Animals eat these plants and then release carbon from these food sources as CO₂ which is taken up from the environment again by plants.

Explanation:
Alexis is using models of the cell membrane to compare the types of cellular transport. One
model shows a molecule entering through a protein pump. Which ope of cell transport is
being modeled?
A
diffusion because protein pumps are needed to move substances from a higher
concentration to a lower concentration
8
endocytosis, because protein pumps transport substances that are too large to
pass through the cell membrane
active transport, because protein pumps are needed to move substances against a
concentration difference
D
osmosis, because protein pumps allow water to cross the cell membrane
Answer:
C. active transport, because protein pumps are needed to move substances against a concentration difference
Explanation:
There are two major types of transport in living cells namely: passive transport and active transport. The passive transport moves molecules down a concentration gradient and hence, do not need energy (ATP) to occur. However, on the other hand, ACTIVE TRANSPORT moves substances against their concentration gradient, thus, require energy input.
Active transport makes use of PROTEIN PUMPS to achieve this process. Hence, in this case where Alexis is using models of the cell membrane to compare the types of cellular transport. The model that shows a molecule entering through a protein pump is modelling ACTIVE TRANSPORT.

Both mitosis and meiosis begin with a diploid cell that contains replicated chromosomes. What are the main differences between these two processes, and what types of daughter cells produced by each? Meiosis has four cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has two cell divisions and results in two identical daughter cells. Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells. Mitosis occurs in gametes to increase genetic variation in daughter cells, while meiosis occurs in body cells for growth and repair. Mitosis produces genetic variation in daughter cells and increases the number of chromosomes, while meiosis occurs in body cells for growth and repair.
Answer:
Meiosis has two cell divisions and results in four haploid daughter cells with genetic variation, while mitosis has one cell division and results in two identical daughter cells.
The main differences would be that Meiosis has 4 cell divisions and Mitosis had 2 cell divisions. Meiosis results in 4 haploid daughter cells and Mitosis results in 2 identical daughter cells.
Another big difference between the two could be that Meiosis produces genetic variation in the daughter cells and increases the number of chromosomes whilst Meiosis occurs in body cells for growth and repair. Each process has a different job.

Answer:
The answer is fossils.
By studying the distribution of different types of fossils, geologists have determined that some tectonic plates have traveled great distances.
Evidence to support this is that -
A. fossils of organisms that lived in warm climates have been found in arctic environments.
B. species of organisms in the fossil record have changed over geologic time.
C. some fossilized organisms have only been found on only one continent.
D. the oldest known fossils, found in the deepest rock layers, represent ocean organisms.
Answer:
the answer is A
Explanation:
The evidence to support the idea that some tectonic plates have traveled great distances is option A, "fossils of organisms that lived in warm climates have been found in arctic environments."
What does the distribution of fossil fuels tells us?The distribution of fossils can provide important clues about how continents and tectonic plates have moved over time. When continents or plates separate, they can carry with them the fossils of organisms that were living in that area at the time. As a result, the same types of fossils can be found in geographically distant locations that were once connected.
For example, the discovery of fossils of tropical plants and animals in polar regions provides strong evidence that those regions were once located closer to the equator and have since moved to their current location. This phenomenon is known as "paleogeography" and has been instrumental in understanding the movement of tectonic plates and the history of the Earth's continents.

F. Lymphatic system
G. Hydrochloric acid
H. Ileocecal valve
I. Enzyme
J. Liver
Answer:
- Controls the entry of chyme into the duodenum: A. Pylorus
- Controls the entry of chyme into the colon: H. Ileocecal valve
- Substance that helps make or break a chemical bond: I. Enzyme
- A component of gastric juice: G. Hydrochloric acid
- Organ that releases bile into the small intestine: E. Gallbladder
- Organ that synthesizes bile: J. Liver
- Fingerlike projection of small intestinal lining: D. Villus
- Absorption mechanism that requires energy: B. Active transport
- Absorption mechanism that does not require energy: C. Diffusion
- Carries fat-soluble vitamins: F. Lymphatic system
Explanation:
The pylorus is a part of the digestive system that connects the stomach to the duodenum. The ileocecal valve is a muscle localized between the ileum of the small intestine and the colon, whose main function is to limit the reflux of colonic contents. Gastric juice is a liquid consisting of hydrochloric acid, lipase, and pepsin, whose main function is to inactivate microorganisms. The gallbladder is a small organ that in combination with the small intestine are reservoirs for bile acid and regulate the biliary secretion of this acid. The bile acid is a fluid secreted by the liver that helps to digest lipids in the small intestine. Intestinal villi (villus in singular) are finger-like projections that increase the surface area for the absorption of nutrients in the small intestine. Active transport is the movement of molecules across cell membranes by using energy from ATP hydrolysis or by using an electrochemical gradient. Diffusion is the movement of molecules across cell membranes from a side of the membrane with higher concentration to the other side with lower concentration. An enzyme is a molecule (generally a protein) that is capable of accelerating the rate of a chemical reaction. Fat-soluble vitamins are absorbed in the small intestine and then they are transported through the lymphatic system to be released into the bloodstream.

There are two different types of cell transportation. Which of the following requires energy?
a. Facilitated Diffusion
b. Active Transport
c. Osmosis
d. Simple Diffusion
please help :))
Answer:
The type of cellular transport that requires energy is active transport (option b).
Explanation:
Active transport —unlike passive transport— involves the passage of molecules or substances through the membrane against a concentration gradient, a process that requires the use of energy.
In the case of active transport the energy for the process comes from the ATP molecule and the mechanism for this to be possible is by means of an ATPase incorporated into the transporter.
The transport of glucose and the sodium-potassium and calcium pumps are examples of this type of transport.
The other options are not correct because simple diffusion, facilitated diffusion and osmosis are passive transport mechanisms that do not require the use of energy.
