This is not biology related question and belongs to algebra or math.

Further explanation

Biologists

They study life and he is a scientific researcher who has specific information in the field of life science or the logical investigation of life.

Mathematician

A mathematician is somebody who uses a broad learning of science in his or her work, ordinarily to tackle numerical issues. Arithmetic is worried about numbers, information, amount, structure, space, models, and change.

Connection between Biology and mathematics

Scientists use math as they plot charts to enable them to get conditions, run little "experimentation" tests with some example numbers when creating calculations, and utilize the R venture for breaking down protein groupings and structures. Scholars likewise use programming with a ton of basic science.

Use of math in research work

Researchers use math to sort out all the various pieces of a cell, an organ or a whole living being to all the more likely see how the parts cooperate and how irritations in these unpredictable frameworks may add to infection. Here and there it's incomprehensible or too hard to even consider answering an exploration question through conventional lab tests, so scientists depend on math to create models that speak to the framework they're examining, regardless of whether it's a metastasizing malignant growth cell or a developing irresistible illness. These methodologies enable researchers to demonstrate the probability of specific results just as refine the exploration questions.

Which energy source did you rank as the worst option for the rescue team

stellarik [79]

Answer:

The worst option of energy source for the rescue team would be - nuclear, hydroelectric, combustion and fuel burning all are worst option fro max to less worst.

Explanation:

The best option for the energy source for the rescue team would be hand canker, lever as it is mechanical energy generator does not require anything but hand movement to generate energy to charge equipment and easily carry anywhere.

Solar, wind energy are also helpful for rescue team but nuclear energy, hydropower, fuel burning energy source are risky, not handy and costly options.

Thus, the worst option are- nuclear, hydroelectric, combustion and fuel burning energy source.

In chloroplasts, ATP is synthesized from ADP plus inorganic phosphate (Pi) in a reaction catalyzed by ATP synthase molecules tha

garik1379 [7]

Explanation:

Complete Question:

A. Blocking electron flow from one carrier to the next in the electron transport chains blocks formation of a proton gradient in the thylakoid.

B. Increasing the proton concentration difference across the thylakoid membrane is not associated with a parallel increase in the rate of ATP synthesis.

C. No ATP is synthesized when channel proteins that allow the free passage of protons are inserted into the thylakoid membrane.

D. No ATP is synthesized while the Calvin cycle is synthesizing carbohydrates and using ATP and NADPH at a high rate.

Correct: C. No ATP is synthesized when channel proteins that allow the free passage of protons are inserted into the thylakoid membrane.

Photophosphorylation describes a process in which the H+ made in previous steps of photosynthesis, and free electrons are used to obtain energy stored as ATP; in the electron transport chain move down the chain the energy they release is used in pumping protons out of the thykaloid space.

The high concentration of H+ from photolysis, outside the leads to increased H+ concentration within the thykaloid space, due to its high permeability. This forms a gradient where there is a differential in the number of protons on either side of the membrane the protons flow into the stroma through the enzyme ATP synthase, which makes the energy storage molecules of ATP from the reduction of ADP and inorganic phosphate, Pi. NAD+ functions as the terminal electron acceptor and is reduced to NADPH.

Thus:

a H+ concentration gradient is required for oxidative phosphorylation in the electron transport chain of the chloroplast, and thus the production of ATP
the H+ ion gradient must favor the flow of electrons into the stroma

The free flow of H+ disrupts the gradient, and H+ cannot flow into ATP synthase to produce ATP.

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

The chloroplast is a membrane bound organelle found in plants. It contains several invaginations of a plasma membrane called the thylakoid membrane. This contains chlorophyll pigments, in stacks called granum, while the internal spaces of the organelle are called the lumen. Liquid surrounds the granum, forming the stroma.

During the light reaction:

Light is absorbed by pigments in phosystem II (PSII). This energy is transferred among pigments til it gets to the reaction center, and is transferred to P680; this promotes an electron to a higher energy level where it then goes to an acceptor molecule.
Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent.
the electron moves down an electron transport chain (to PS I)where it experiences continuous energy loss. This energy fuels the pumping of H+ from the stroma to thykaloid, leading to the formation of a gradient. The H+ move along their gradient and cross through ATP synthase, into the the stroma.
ATP synthase converts ADP and Pi to the energy storage molecule ATP.
The electron gets to photosystem I where it goes to pigments at P700. It absorbs light energy, the electron is promoted to a higher energy level, and passed to an electron acceptor. This leaves a space for another electron which is then replaced by one from photosystem II.
in the ETC, the molecule NADP is reduced to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.

The nutritional energy content (in Calories) present in 86g of broccoli with 2.6g of protein, 6g of carbohydrates, and 0.3g of f

Nimfa-mama [501]

Answer:

40 Cal

Explanation:

Data provided in the question:

Protein present in the broccoli = 2.6 g

Carbohydrates present in the broccoli = 6 g

Fat present in the broccoli = 0.3 g

Now,

We know,

Energy provided by protein and carbohydrates = 4 Cal / g

and,

Energy provided by Fats = 9 Cal / g

Therefore,

Total nutritional energy content = ∑(Amount × Energy provided)

= ( 2.6 × 4 ) + (6 × 4) + (0.3 × 9)

= 10.4 + 24 + 2.7

= 37.1 Cal

rounding off the answer to nearest 5 ≈ 40 Cal

A study is being done to test the affects of habitat space on the size of fish populations. different sized aquariums are set up

qwelly [4]

Although not specified, I am assuming that you want to identify the different variables and groups of this case. To answer this, the different typical factors that make up an experimental set up include: 1) dependent and 2) independent variables; 3) controlled variables; as well as the 4) control and 5) experimental group.

The dependent variable in this case is: the size of the population. While the independent variable is: the habitat space. Controlled variables in this experiment include: type and amount of food, cleanliness of the aquarium, and water temperature. The experimental group are simply the fish being observed. There are no controlled groups in this case depending on your definition. Controlled groups are usually the reference point or standard in experimental setups but this experiment wants to look at the differences of the goldfish with each other and not necessarily to a one particular goldfish and hence no controlled group.

The dependent variable is called as such because it is the one that changes depending on the factors given and is usually the one being observed. The independent variable is named as such because it remains the same throughout the experiment.

The rate of O2 production by the light reactions varies with the intensity of light because light is required as the energy sour

kupik [55]

Answer:

The correct answer is option a.

Explanation:

Yes, the light reactions also depend upon the Calvin cycle. Calvin cycle refers to a phenomenon that is used by the plants and algae to convert carbon dioxide from the atmosphere into sugar, the food needed by the autotrophs in order to grow. The plants rely upon the Calvin cycle for food and energy.

In the given case, the rate of oxygen production would get diminish as the rate of ATP and NADP+ generated by the Calvin cycle diminishes. Of all the outcomes of the Calvin cycle, ADP and NADP+ are the only ones that get utilized by light reactions.

The ADP and NADP+ are used up by the light reactions to fuel their reactions. This illustrates that if the rate of ADP and NADP+ generated by the Calvin cycle diminishes the production of oxygen by the light reactions also diminishes.
