Answer:
During photosynthesis a plant takes in water, carbon dioxide and light energy, and gives out glucose and oxygen. It takes light from the sun, carbon and oxygen atoms from the air and hydrogen from water to make energy molecules called ATP, which then build glucose molecules.
The enzyme threonine deaminase, in addition to being controlled by feedback inhibition, is controlled by _____.
Answer:
noncompetitive inhibition
Explanation:
Non-competitive inhibition (also known as allosteric inhibition) is a type of enzymatic reaction where an inhibitor binds to the enzyme and thus reduces its enzymatic activity. Non-competitive inhibitors are known to bind with the enzyme at allosteric sites, i.e., at different sites rather than the active site. In consequence, during non-competitive inhibition, the substrate can still bind to the enzyme, although that binding to the inhibitor reduces its catalytic efficiency. Conversely, competitive inhibition is produced when the inhibitor binds to the enzyme at the active site, thereby preventing from binding to the substrate.
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.

cell, the
has a similar purpose.
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.

Genes C and D are linked with a recombination frequency of 0.4. Both genes segregate dominant (C and D) and recessive alleles (c and d). The parental cross CCDD x ccdd is performed and then the F1 progeny is testcrossed to ccdd. If 10 individuals are counted in the F2, how many are expected to be dominant for BOTH genes
Answer: 3 individuals.
Explanation: Recombination frequency is the proportion of offspring who will inherit the recombinant genes.
The F1 progeny has genotype CcDd. When crossed with an individual with genotype ccdd, F2 generation can be CcDd or ccdd in a 50/50 probability.
The recombinant frequency is 0.4, which means in a total of 10 individuals of F2, 4 will be recombinant, so 6 will be parental, i.e., will carry the same genes of their parents.
From the population of 6, half of them will carry dominant genes for both features, so:
6 x 0.5 = 3
Therefore, from 10 individuals of F2, we expected 3 to be dominant for both genes.

How are the rock cycle and the water cycle related?
Answer:
The processes are condensation, precipitation, evaporation and transpiration. The rock cycle and water cycle overlap with erosion, transporting, and deposition. This is where the life cycle interacts with the rock cycle. Life decomposes and releases carbon back into the soil, which eventually becomes sedimentary rock.
Explanation:
The process of natural selection favors certain characteristics in organisms, while it selects against other characteristics.What would happen if there was zero variation between all of the organisms on Earth?
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.

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.

8. What abiotic factors distinguish different biomes?
The abiotic factors like temperature, precipitation (rainfall), and the intensity of wind are primarily responsible for distinguishing different biomes.
What are Biomes?A biome may be defined as a very large ecosystem that is running in nature in an unmanaged way. In a more simple sense, it is a very large area that is characterized by a particular type of vegetation. Some examples of biomes include tropical rainforests, coral reefs, grasslands, etc.
In tropical rainforests, rainfall is found to be greater than 230cm per year and temperature may range from 25-29°C. In tropical deciduous forests, temperatures may range from 25-39°C and rainfall is found to be 130-280 cm. per year.
In temperate rainforests, the temperature on average ranges from 5-25°C, and rainfall is 200 cm per year. In temperate deciduous forests, the temperature is 12°C and rainfall may range from 75-200 cm per year.
Therefore, abiotic factors like temperature, precipitation (rainfall), and the intensity of wind are primarily responsible for distinguishing different biomes.

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.
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.
