do you think a hand-crank flashlight would be a good energy system for the rescue workers? Why or why not?

Answers

Answer 1

Answer:

No.

Explanation:

No, hand-crank flashlight would not be a good energy system for the rescue workers because the light turns on by applying muscle force on the hand-crank flashlight and after that, the device convert muscle force into electric energy and the light turns on and we know that the rescue worker have a tough job which requires both hands so this hand-crank flashlight is not useful to him.

Answers

Answer:

A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less.

Explanation:

A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less. Several factors affect the rate at which enzymatic reactions proceed include post translational modifications, substrate concentration, cofactors, temperature, pH, locations. The shape and structure of the enzyme will change as the pH value of the reaction medium changes.

A cell may vary the rate of an enzyme controlled reaction by:

Degrading with time

According to the given question, we can see that we need to show how a cell can vary the rate of a reaction which is controlled by an enzyme.

As a result of this, we can see that there are different ways through which a cell may control the rate of reaction in an enzyme controlled state which are by the level of degradation with time.

Models of the human immunodeficiency virus (HIV) and an animal cell are shown below.

Answers

Answer:

The cell membrane is selectively permeable, which controls the movement of materials in and out of the cell by passive and active transport.

Explanation:

According to this question, animal cells are made up of the following contents: 90% water and 10% protein, carbohydrates, nucleic acid, lipids and other molecules. The cell regulates this internal composition in a stable way via a process called HOMEOSTASIS.

The animal cell is able to regulate or maintain a stable internal composition by the possession of a selective permeable membrane called CELL MEMBRANE. The cell membrane is semi-permeable in the sense that it allows the entry of some molecules into and out of the cell and blocks others.

Some molecules are allowed by the cell membrane without the need for energy input in a transport called PASSIVE TRANSPORT while some requires energy input in a transport called ACTIVE TRANSPORT.

What is a function of the respiratory system?

Answers

Answer:

The respiratory system's main purpose is to move fresh air into your body and moving waste gasses out (like carbon dioxide when you breathe out)

The function of the respiratory system is to inhale oxygen which is absorbed by red blood cells in the lungs. The RBC then go to the heart which pumps the oxygenated blood to the rest of the body and non oxygenated blood goes back to lungs to be oxygenated. They also carry back waste such as carbon dioxide to the lungs to be exhaled.

How do i know if its entering or leaving or neither just by the precentage?

Answers

Answer:

1. Shrink

2. Swell

3. Neither

Explanation:

The percentage of water indicates how pure the water is, i.e. how concentrated the molecules of water are.

The higher the percentage of water, the more water molecules there are in the space.

Water molecules move from a high concentration to a low concentration across a semi permeable membrane, by the process of osmosis.

In beaker 1, the water outside is 89%, and inside the bag is 92%. That means the water inside the bag is at a higher concentration than outside. That means water will leave the bag, moving from a high concentration to a lower concentration outside. The bag will shrink.

In beaker 2, the water outside is 97%, and inside is 92£%. That means the water inside the bag is a lower concentration than outside. That means water will enter the bag, moving from a higher concentration outside to a lower concentration outside. The bag will swell.

In beaker 3, the concentration of water inside and outside is the same. That means they are in an equilibrium (the movement is balanced) so neither will occur

Is mass conserved in chemical reactions?

Answers

Answer:

Mass is not conserved in chemical reactions. ... This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass.

Explanation:

Answer:

Mass is not conserved in chemical reactions. The fundamental conservation law of the universe is the conservation of mass-energy. This means that the total mass and energy before a reaction in a closed system equals the total mass and energy after the reaction. According to Einstein's famous equation, E = mc2, mass can be transformed into energy and energy can be transformed into mass. This is not some exotic process, but in fact happens every time there is a reaction. Mass is therefore never conserved because a little of it turns into energy (or a little energy turns into mass) in every reaction.

When does facilitated diffusion occur?

Answers

Answer:

The word ‘diffusion’ means free movement across distance, with or without the presence of a barrier. However, there is a phenomenon known as facilitated diffusion which occurs at the cellular level. The cell does not allow free radicals and other harmful substances to enter and harm the cell organs.

Explanation:

Answer:

When certain large molecules are unable to move through the membrane without the help of channel proteins.

Explanation:

Facilitated diffusion occurs when large molecules that are unable to pass through a membrane on their own make use of channel proteins to move from one side of the membrane to the other. Facilitated diffusion can occur when a liquid on one side of a membrane has a higher osmotic pressure than a liquid on the other side of the membrane, but it isn’t a required feature of facilitated diffusion. Similarly, facilitated diffusion can occur when there’s a large membrane potential present, but it isn’t a required feature of facilitated diffusion. Facilitated diffusion doesn’t require the use of energy, so the presence of ATP is irrelevant to facilitated diffusion occurring.
