Enzymes need certain environmental conditions in order to function properly. what happens when enzymes are heated to a high temperature?
When enzymes are heated to a high temperature, they can denature, losing their structure and function. Similarly, extreme pH values can also cause denaturation of enzymes.
Explanation:Enzymes need certain environmental conditions in order to function properly. When enzymes are heated to a high temperature, they can denature, losing their three-dimensional structure and function. This is because high temperatures can break the chemical bonds within the enzyme's active site, making it less well-suited to bind substrates. Enzymes also function optimally within a certain pH range, and extreme pH values can also cause denaturation of enzymes.

Skulls can reveal many things about our hominid ancestors. What aspect of hominids is not related to skull anatomy?
A. What they ate.
B. Their hair and skin color.
C. Whether they stood upright.
D. The shape and size of their brain.
The answer is B.
Choice A is wrong because what they ate is how the skull is shaped and how the skull uses itself to find and eat food.
Choice C is wrong because it went over that in the Gizmos activity
Choice D is wrong because their brain was in their skull to help shape how the skull looked like.
The correct answer is - B. Their hair and skin color.
The hair and skin color of the hominids is not related to the shape and size, or rather the anatomy of the skull. The development of hair and skin color is actually dependent on the surrounding environment, since it can be used for camouflage, for protection of cold, or protection of the sun, but it has nothing to do with the bone structure of the skull.
The anatomy of the skull is defined by the eating habits, the way of motion, the size and the shape of the brain.
Plant A and Plant B are heterozygous for a gene that expresses their tall trait (Tt). Upon crossing, what is expected in the offspring, assuming random chromosome segregation?
Answer:
The Plant A is heterozygous for the gene expressed their tall trait (Tt) and Plant B is also heterozygous for the same trait.
( Plant A ) Tt X Tt ( Plant B) = TT Tt Tt tt
The products are 75 per cent tall by phenotype and 25 per cent dwarf by phenotype.
If the cross between the two heterozygous gene is done which shows the trait as tall, and then the offspring will have 75% as tall plant and 25 % as dwarf plant.
Although the reactions of the calvin cycle are not directly dependent on light, they usually do not occur at night. why?
The Calvin cycle does not directly depend on light, but it relies on the products of the light-dependent reactions in photosynthesis. Therefore, it usually does not occur at night.
Explanation:The Calvin cycle, which is the process by which plants convert carbon dioxide into glucose, does not directly depend on light. However, it usually does not occur at night because it relies on the products of the light-dependent reactions in photosynthesis. These reactions occur during the day when sunlight is available, and their products, such as ATP and NADPH, are necessary for the Calvin cycle to take place.

Which communities do early colonizers form?
Early colonizers result in the formation of communities.
Answer:
The correct answer is ecological communities.
Explanation:
The early colonizers result in the generation of ecological communities. The formation of these communities starts with a few animals and plants, which afterward develops into a complexity. They become self-perpetuating or stable in the form of a climax community. Their succession results in a change in the ecosystem, that is, the established species with the surrounding.
during dna replication in a human cell, 6 billions bases must be paired properly. which characteristic of dna best allows for high level of accuracy during this process
Answer: The complementary base pairing helps in proper pairing of the bases.
Explanation:
The complementary of base pair shows that the adenine will only bind to the thymine and the guanine will only bind to the cytosine and with any other base pair.
So, the template no matter how long it is, the adenine in them will bind to the thymine and the cytosine will bind to the guanine.
The bonds in between are double hydrogen bond in case of adenine and thymine and triple hydrogen bond in case of guanine and cytosine.
This aids in pairing of 6 billion bases during the time of DNA replication in human beings.
What is iodine solution changing from amber-yellow to blue-black an indication of?
a.the presence of reducing sugars or monosaccharides
b.the presence of proteins or peptide bonds
c.the presence of lipids or fats
d.the presence of starches or complex carbohydrates submit for grading save and finish later?
Iodine solution is prepared by dissolving iodine in a solution of potassium iodide. This iodine reagent is amber-yellow colored. When this iodine solution is added to starch solution which is a polysaccharide, the yellow colored reagent changes to blue-block color. This color change is due to the formation of a charge transfer complex between starch and the triioidide present in iodine solution. So, the correct answer is d. the presence of starches or complex carbohydrates

The least amount of atp is produced in which stages of cellular respiration
The least amount of ATP is produced in the Krebs cycle of cellular respiration. This stage produces only two molecules of ATP.
What are the different stages of cellular respiration?There are three different stages of cellular respiration are there:
Glycolysis: Breakdown of glucose into pyruvate.The Krebs cycle: Pyruvate gets converted into acetyl-CoA which enters TCA.Electron transport chain: The product of the TCA cycle enters into the electron transport chain.The process of glycolysis produces 4 ATP and 2 NADH. But 2 ATP is spent which leads to the net production of 2 ATP and 2 NADH. The process of the Krebs cycle involves the breakdown of acetyl-CoA into 2 ATP, 8 NADH, and 2 FADH2. While the process of the electron transport chain produced 34 molecules of ATP with the help of the conversion of all energetic carriers.
Therefore, the least amount of ATP is produced in the Krebs cycle of cellular respiration. This stage produces only two molecules of ATP.

An opening in the dermis through which perspiration reaches the surface of the skin is called
An opening in the dermis through which perspiration reaches the surface of the skin is called pores.
Explanation:
Skin is the second largest organ of the human body. The skin in order to regulate the body temperature expels the liquid in the form of sweat. This sweat is normally not pure water. It is a mixture of water with minerals and salts. This process is called as the perspiration. Skin has got sweat glands which is present throughout the body.
This sweat gland through the small holes called pores that expel the sweat. Normally we sweat through arm pits, face, palm of hands and sole of the foot. Women tend to sweat more than men. A normal pure sweat is odorless hence distinctive odor in the sweat can help us identify certain differences the body is undergoing .

They cool down.
none of the above
Answer:
2. December 21
3. They move faster.
Explanation:
2. The midnight sun or polar day is a natural phenomenon observable in the north of the Arctic Circle and south of the Antarctic Circle, consisting of that, on dates close to the summer solstice, the Sun is visible 24 hours a day.
3. The energy makes the air particles move faster, they collide with others that are at a lower temperature, that move more slowly. As they collide, fast particles yield some of their energy to slower ones. These in turn collide with other adjacent particles. This process continues until the energy is extended to all the particles of the air that was initially at a lower temperature. Finally they all reach the same kinetic energy and consequently the same temperature.

Which type of microscope is needed to view a virus in the laboratory?
which arrows represent photosynthesis and cellular respiration?
3rd arrow represents photosynthesis and 4th is cellular respiration.
What is cellular respiration?Cellular respiration is the process by which cells break down glucose and other organic molecules to release energy in the form of ATP (adenosine triphosphate). It is a metabolic process that occurs in the cells of all living organisms and involves a series of biochemical reactions that convert the chemical energy stored in glucose into a more usable form of energy (ATP).
The process of cellular respiration occurs in three stages: glycolysis, the Krebs cycle (also known as the citric acid cycle), and oxidative phosphorylation (also known as the electron transport chain). Cellular respiration is essential for life as it provides the energy needed for cells to carry out their functions and maintain homeostasis.
