If you were on the moon, and you were trying to move a 20-lb bowling ball and a 3-foot cube of Styrofoam, which item would take more work to move? Why?

Answers

Answer 1

Answer:

The 20 lb bowling ball would take more work to move. This is because it has more mass

Explanation:

It is the bowling ball that will take more work to move. The reason for this is simple. Mass is constant anywhere, whether it is on the moon or on the earth.

It is the acceleration due to gravity that is different in both places. Work as we all know is a factor of mass, the higher the mass, the more work it will take to displace the mass from its position.

Thus, because the mass of the bowling ball is greater, it will take more work to move than the styrofoam

Compare substrates and inhibitors.​

Answers

Explanation:

An enzyme inhibitor is a molecule that binds to an enzyme and decreases its activity. ... Not all molecules that bind to enzymes are inhibitors; enzyme activators bind to enzymes and increase their enzymatic activity, while enzyme substrates bind and are converted to products in the normal catalytic cycle of the enzyme.

Arginine utilizing enzymes in macrophages showed different specificities for various arginine analogues and derivatives as substrates and inhibitors. Isolated arginase was strongly inhibited by L-canavanine(Can) and L-ornithine(Orn) but only slightly by L-homoarginine(Hom) and L-argininamide(ArgNH2). These effects were not or only weakly observed when released urea was measured in long term cell cultures. On the other hand, both L-canavanine and L-argininamide were substrates for arginase in long-term cultures. The known inhibitors of NO synthase were ineffective. The mechanisms of inhibition were different for L-canavanine and L-ornithine, but clear mechanisms could not be identified). NO synthase was studied only in long term cell cultures without purification. Certain N-guanidino (NG)-substituted arginine derivatives caused a marked inhibition while inhibitors of arginase had only slight or no effect. L-homoarginine was also found to be the substrate of NO synthase. The comparison of these effects of arginine analogues and derivatives made possible a computer-aided approximation for the fitting of active centers of these enzymes to their substrates.

QUESTION 2: In 2016, the wolf population on Isle Royale declined to only two individuals. How will the lack of wolves affect the moose population? Will the moose population grow exponentially? Use past evidence from the graph to support your answers.

Answers

The lack of wolves affect the moose population through environmental changes. The moose population will grow exponentially which means they’ll need more food. If the moose doesn’t have enough food, they will change location and steal another source of food for another herbivore

If wolves population decreases then the moose population increases.

Ecosystem:

The ecosystem is a complex living organism, its physical environment, and its interrelation with other organisms.

In the ecosystem there are food chains are present. In food chains, there are different trophic levels present. If one trophic level is affected it will affect the entire food chain.

Plants are the primary producers, moose will be the primary consumers and Wolves will be the secondary consumers, If population of secondary consumer will decrease it will affect the population of primary consumer.

The wolf population on Isle Royale declined to only two individuals. If the population of wolves decreases then the moose population increase exponentially.

Therefore, If wolves population decreases then the moose population increases.

What is the variable that affects enzyme function in the example of phosphofructokinase-1?

Answers

Answer:

This question is incomplete

Explanation:

The question is incomplete because the example referred to was not stated. However, phosphofructokinase-1 is a key enzyme in glycolysis; it converts/phosphorylates fructose-6-phosphate to fructose-1,6-bisphosphate in the presence of ATP to release ADP. It is a regulatory enzyme in this pathway (glycolysis) because it's function can be affected by an increased ATP to ADP ratio which inhibits the enzyme (phosphofructokinase-1) and indeed glycosis itself.

You planted both trees in your sunny backyard , gave both of them the same amount of waterbut you gave one tree the special fertilizer and the other tree with the regular old fertilizer you've used before . After about a month , you noticed that the tree that got the special fertilizer grew over 100 apples than the other tree that grew about 40 apples . From this experiment , which of the following is considered the dependent variable ?

Answers

Answer:

Dependent variable: number of apples

Explanation:

In an experiment, the independent variable is the variable that isn't modified by the other variables measured in the experiment. In the example above indicated, the independent variable is the fertilizer used in the experiment. On the other hand, the dependent variable is the variable tested or measured in the experiment, thereby this variable is 'dependent' of the independent variable.

James adds some magnetic marbles to a glass jar full of ordinary marbles, and then shakes up the jar. What do you think will happen to the magnetic marbles?

Answers

Answer:

Magnetic marbles will tend to attract each other.

Explanation:

Magnetic marbles are composed of ferromagnetic materials, which indicates that they function as a magnet and have the ability to attract other objects formed by ferromagnetic materials. In this case, we can say that the magnetic marbles attract each other and inside a jar containing magnetic marbles and common balls, the magnetic marbles will tend to attract and group together.

When James shakes the glass jar ; The magnetic marbles will attract each other

   The magnetic marbles will attract each other because of the ferromagnetic materials that each magnetic marble contains. marble is a rock ( metamorphic ) that is made up mainly of calcium carbonate .

   when rocks/compounds contain ferromagnetic materials they will act as magnets thereby attracting any metallic object or any magnetic material within close proximity. therefore the magnetic marble will attract each other inside the glass jar

Hence we can conclude that When James shakes the glass jar ; The magnetic marbles will attract each other.

1. Describe how photosynthesis and chemosynthesis differ in terms of how energy is converted,

Answers

Answer:

1) Photosynthesis:

Reactants- 6CO2 (carbon source), 6H2O, light energy

Products- C6H12O6 (organic molecule), 6O2

2) Chemosynthesis:

Reactants- 6CO2 (inorganic carbon source), 6H2O, 3H2S ( chemical energy source)

Products- C6H12O6 (organic molecule), 3H2SO4

Please find the difference in terms of how chemosynthesis and photosynthesis convert energy below

Explanation:

Photosynthesis and Chemosynthesis are both autotrophic forms of nutrition. They differ in the form of energy and reactants' used to power their respective processes.

- Photosynthesis is the process whereby plants synthesize their food (glucose) from carbon dioxide (CO2) and water (H20) in the presence of sunlight as energy, releasing oxygen gas (O2) as a product.

6CO2 + 6H2O -> C6H12O6 + 6O2

- Chemosynthesis, on the other hand, is the process whereby certain bacteria and fungi that lacks access to light synthesize organic food (glucose) from an inorganic carbon soure (carbon dioxide, CO2), water (H2O), and hydrogen sulfide (H2S), used as chemical energy source, releasing sulfates (H2SO4) as a product

6CO2 + 6H2O + 3H2S -> C6H12O6 + 3H2SO4

However, photosynthesis converts solar energy (energy in sunlight) to chemical energy (in glucose) while chemosynthesis converts inorganic chemical energy to organic chemical energy.

The chemical reaction(reactant and product) for photosynthesis and chemosynthesis are  as follows:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

18H₂S + 6CO₂ + 3O₂ → C₆H₁₂O₆ (carbohydrate) + 12H₂O + 18S

Photosynthesis reaction:

6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂

This reaction is a reaction between carbon dioxide and water to form sugar and Oxygen in the presence of sunlight.

The chemical equation of photosynthesis can be interpreted as 6 molecules of  carbon dioxide reacting with 6 molecules of water to form a simple sugar and 6 oxygen molecules in the presence of sunlight . The names of the reactant and products are as follows:

carbon dioxide + water → Sugar + oxygen

Chemosynthesis reaction:

Chemosynthesis is the conversion of carbon compounds and other molecules into organic compounds.

Using H₂S as an energy source a chemosynthetic reaction can be represented below:

18H₂S + 6CO₂ + 3O₂ → C₆H₁₂O₆ (carbohydrate) + 12H₂O + 18S

From the reaction Hydrogen sulphide was used as a source of energy and it reacts with carbon dioxide and oxygen to produce sugar, water and sulphur.

Hydrogen sulphide + carbondioxide + oxygen →  Sugar + water + sulphur.

Answers

Answer: DNA codes for our genotype, which is the genetic representation of out traits. There are multiple kinds of RNA but it is mostly used to aid the replication of DNA.

Explanation: DNA is the strand of nucleic acid, sugars and phosphate group, that is found in the nucleus and mitochondria of every cell. It codes for our genotype, which is essentially the written representation of our traits. There are multiple kinds of RNA but they are mostly used to replicate DNA, they are single stranded as opposed to the double stranded DNA and include the nitrogen base uracil (U), instead of thymine (T). mRNA, tRNA and dsRNA are commonly used to replicate and regulate the DNA sequence.

Answer:

The two main types of nucleic acids are DNA and RNA. Both DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base. DNA provides the code for the cell 's activities, while RNA converts that code into proteins to carry out cellular functions.

Explanation:

RNA:

The central dogma of molecular biology suggests that the primary role of RNA is to convert the information stored in DNA into proteins.

DNA:

The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the instructions to construct other components of the cell, such as proteins and RNA molecules.
