What is the gradient formula?
Explanation:
The gradient of the line = (change in y-coordinate)/(change in x-coordinate) . We can, of course, use this to find the equation of the line. Since the line crosses the y-axis when y = 3, the equation of this graph is y = ½x + 3 . To find the gradient of a curve, you must draw an accurate sketch of the curve.

Which of the following require clear warning signs or labels? Check all that apply
The options that would clearly require the use of warnings would be:
Places where a spill was recently cleanedContainers with bodily fluidsWhat is a warning sign?This is the term that is used to refer to the signs that are placed in objects so that it would serve as precaution to the people around who may come in contact with those objects.
The goal of the warning sign is to ensure that people do not suffer un desirable consequences when they get in contact with these items which may have the potentials of causing them harm.
For instance bodily fluids that are infected may be harmful to other people hence the need to ensure that it is well protected and has all of the right labels on it.
Also area that spills have occurred may be radioactive area as and they may be dangerous to the health of persons that go near them.

Dinitrophenol (2,4-DNP) destroys proton gradients without affecting anything else about a membrane. Its pKa slightly acidic, so it can be protonated or unprotonated in cells.a. What would be the effect of adding dinitrophenol to the mitochondrial inner membrane
Answer:
the effect of adding dinitrophenol to the mitochondrial inner membrane is -:
Production of ATPNo electron transferproduction of more sugar as energyUncoupling of ETC(electron transport chain)Explanation:
Dinitrophenol is an uncoupler which can isolate the progression of electrons and siphoning of H+ particles for ATP Synthesis. On adding the dinitrophenol, the energy from the electron move can't be utilized for ATP blend. It has been utilized in diet pills and as a counting calories help. It goes about as protonophore and permits spillage of the protons through the internal mitochondrial layer which subsequently sidesteps ATP synthase and consequently the creation of ATP creation gets wasteful. It hinders the ATP synthase and thus its capacity to deliver ATP. It likewise influences the ETC in light of the fact that forestalls development of electrons over the ETC. Uncoupling the ETC would prompt diminished ATP creation and consequently increasingly more sugar is used as energy. This would restrict accessibility of ATP and make a deadly circumstance.

Explain the process that creates wind.
Answer:
Winds are caused by differences in air pressure. Unequal heating of Earth’s surface creates areas of different pressure. Cooler areas have higher air pressure. Warmer areas have lower pressure. This causes air to move from high pressure to low pressure. This movement is the wind we feel.
Answer:
Wind is air in motion. It is produced by the uneven heating of the earths surface by the sun. since the earths surface is made of a various land and water formations, it absorbs the sun's radiation unevenly. Two factors are necessary to specify wind which is speed and direction.

What type of light is trapped in the Green House
Answer:
infrared light
Explanation:
The Earth absorbs this energy from the Sun and reemits it in the form of invisible infrared light. This energy is trapped by the greenhouse effect. Greenhouse gases have various shapes that make them effective at absorbing infrared radiation emitted by Earth.
It is a light called an infrared light.
Only the light in the visible spectrum can penetrate into the greenhouse whereas incoming infrared light, which is also known as heat radiation, is blocked by the glass or plastic.

A)
Golgi body
B
mitochondria
C
plasma membrane
D
endoplasmic reticulum
Answer:
Explanation:
C.
In this animal cell, the has a similar purpose as of skin is plasma membrane. The correct option is C.
What is plasma membrane?The membrane that basically divides the interior of the cell from the external environment is known as the plasma membrane, sometimes known as the cell membrane, and it is present in all cells.
The cell membrane isolates a cell's interior contents from its external environment, just like your skin's outer layer does for your body and its surroundings.
The cell membrane acts as a barrier to protect it and controls what can enter and leave the cell.
One of the body's first lines of defense against hazardous germs is the skin, which acts as a barrier. Skin tissue contains specialized immune cells that aid in the defense against invaders.
The skin, however, is home to a variety of communities of helpful bacteria known as the skin microbiota.
Thus, the correct option is C.

What must match between a virus and a host cell?
A)DNA= Cell DNA
B)RNA=ribosome
C)envelope proteins= cell receptors
D)blood types
Answer:
C)envelope proteins= cell receptors
Explanation:
To enter the cell, the virus must bind to receptor proteins on the cell surface It does so via its envelope proteins. When the receptors and the envelope proteins match, the virus can become engulfed into the cell.
Once it enters the cell, the hijacks the cell's transcription and translation machinery and causes the viral proteins to be expressed. The viral proteins assemble into viral particles. Eventually, the cell bursts and the viral particles are released.
