The students in Mrs. Cosby's class were observing worms. The students wanted to find out if a worm's body weight is related to how much food it eats. For their experiment, the students set up five containers in the same place, each with the same type of worm. They measured the starting weight of each worm before they began, and then offered the same amount and type of food to all the worms. What data must they collect during their experiment?

Answers

Answer 1
Final answer:

To answer the question, the students should collect data on the starting weight of each worm and measure their weight again after offering them the same amount of food.

Explanation:

The students in Mrs. Cosby's class want to find out if a worm's body weight is related to how much food it eats. To answer this question, they should collect data on the starting weight of each worm before they begin the experiment. They should also measure the weight of each worm again after offering them the same amount and type of food. By comparing the starting and ending weights, they can determine if there is a relationship between the worm's body weight and the amount of food it eats. Comparing the starting and ending weights will help determine the relationship between a worm's body weight and the amount of food it eats.

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.

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.

Answers

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.

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?

Answers

The answer is D. Iodine is used to test for starches and, in the presence of a starch, it will turn a dark blue-black color.

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 Antarctic Circle has 24 hours of daylight around the summer solstice. In the southern hemisphere this would be around December 21.

When energy is transferred to air the particles of air move faster. Adding energy to molecules makes them move faster and air is no exception.

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.

Answers

change the bonds between amino acids in the enzyme, so changing its shape
Final answer:

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.

The least amount of atp is produced in which stages of cellular respiration

Answers

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules.

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.

List three reasons that can help explain why it is important to distinguish different tastes?

Answers

Different vital nutrients have broadly unique tastes. We all require certain amounts of nutrients, such as sugars or salts for example, in our diet. The tastes of these broad characteristics of nutrients are fairly distinct from each other, and this allows us to consume the correct foods when we require a particular nutrient in our diet.

Some substances that can be harmful to us in large amounts have disagreeable tastes, such as acidic foods for example.

Taste is one of our primal senses that may have had a more important role in the past than just tasting food. For example, territorial animals like wolves often 'taste' the scent to other wolves that have been in an area.

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

Answers

base pairing according to certain rules


i think that would be it

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.

Final answer:

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.
