Answer:
The 2 ohm branch
Explanation:
Since the resistors are in parallel, they are each connected to the same volatage. Since I = V/R you can see that the one with the smallest resistance will have the greatest current through it .

Which type of carbon fixation stores carbon dioxide in acid form? a. c3 b. c4 c. cam d. all of the above
The type of carbon fixation stores carbon dioxide in acid form is CAM i.e. crassulacean acid metabolism.
What are CAM?CAM stands for crassulacean acid metabolism in this process photosynsthesis is occured at day time but the exchange of gases takes place at night itself only.
In this carbon fixation process, carbon dioxide is stored in the form of organic acid malic acid and losses carbon dioxide at the night time and by doing this it helps in the storage of water.
Hence option (C) is correct.

Which best describes the forces in the nucleus of a stable atom?
O A. The weak nuclear force is greater than the electrostatic force.
O B. The electrostatic force is greater than the strong nuclear force.
O c. The weak nuclear force balances out the strong nuclear force.
O D. The strong nuclèar force balances out the electrostatic force.
Best describes the forces in the nucleus of a stable atom is the strong nuclear force balances out the electrostatic force.
The center region of an atom, which is composed of two different types of particles, is known as the atomic nucleus. Protons with positive charges and neutrons with no charges are present. Because of the strong electrostatic attraction between positively charged protons, atomic nuclei should be unstable, however they occasionally remain stable for more than a billion years.
The stability of nuclei suggests that protons and neutrons are attracted to one another by an attractive force. The strong nuclear force, also known as the residual strong force, is responsible for every individual atomic nucleus' stability. Neutrons and protons are held together by this basic force of nature. It is used to explain the atom's and its nucleus' stability, which is otherwise puzzling. It can be used to explain the origin of all atoms and, consequently, the origin of all known simple and complex molecules.

Differences in the density of seawater cause it to move. True or false?
True
False
Answer:
True
Explanation:
Differences in water density affect vertical ocean currents (movement of surface ocean water to the bottom of the ocean and movement of deep ocean water to the surface). … Denser water tends to sink, while less dense water tends to rise.
Differences in the density of seawater cause it to move. Therefore, the given statement is true.
What is density?The substance's mass per unit of volume is known as its density (volumetric mass density or specific mass). Although the Roman letter D may also be used, the sign most frequently used for density is (the lower case Greek letter rho). Density is calculated mathematically by dividing mass by volume.
Where m represents the mass, V is the volume, and is the density. Density is sometimes roughly characterized as weight every unit volume, while this is incorrect technically; this quantity is much more precisely known as specific weight. One example of this is in the US oil and gas business. Differences in the density of seawater cause it to move.
Therefore, the given statement is true.

what is emission spectrum and absorption spectrum?
Answer:
When matter interact with EMR then spectrum is obtained. We can understand both spectra using Bohr's hydrogen spectrum. let's have a look on Bohr's hydrogen spectrum what does it say. It says when a electron gains energy it moves from one energy level to other(lower to higher) which is Absorption phenomenon. When the electrons returns from excited state to ground state they emits several spectral lines. this spectrum is called as emission spectrum. inshort the
Emission spectrum is spectrum of electromagnetic radiations that were emitted from the higher energy state(Excited state) to lower energy state(Ground state). and study of emission spectrum is known as AES (Atomic Emission spectroscopy).
When an atom or ion is subjected to EMR, it absorbs certain level of radiations, and when this absorbed energies are studied under spectroscopy they are plotted as absorption spectrum, and study of Absorption spectrum is known as AAS (Atomic Absorption spectroscopy).

If a gas has a volume of 1.25 l at a temperature of 300 k, what will the volume change to if the container is cooled to 200k
The volume of the gas when the container is cooled from a temperature of 300 K to 200 K is 0.83 L
Charles' law
Charles' law states as follow:
V₁ / T₁ = V₂ / T₂
Where
V₁ is the initial volume T₁ is the initial temperature V₂ is the new volume T₂ is the new temperature How to determine the new volumeFrom the question given above, the following data were obtained
Initial volume (V₁) = 1.25 LInitial temperature (T₁) = 300 KNew temperature (T₂) = 200 KNew Volume (V₂) =?V₁ / T₁ = V₂ / T₂
1.25 / 300 = V₂ / 200
Cross multiply
300 × V₂ = 1.25 × 200
Divide both side by 300
V₂ = (1.25 × 200) / 300
V₂ = 0.83 L

Nucleic acids
Explanation:

Explain why you usually can’t use just a single spectral line to confirm the identity of an element.
You can't usually just use a single spectrum line to confirm the identity of an element because there are cases that the emission line id not clearly defined. When the emission line is very weak compared to surrounding noise, in which case the more datapoints you have to build up confidence for the existence of a particular emission spectra, the better.

The enthalpy change of condensation of water is negative and here the entropy change also negative and the process is nonspontaneous.
What is enthalpy change?The enthalpy change of a reaction or a phase change is the change in heat energy absorbed or evolved. The change in enthalpy is dependant on the nature of process as well on temperature of the system.
Condensation of water is the change of its liquid state into solid state. Thus water freezes to form ice. In this process, the system is getting more ordered structure in the solid state and thus, the entropy of the system decreases means the entropy change is negative.
Now, when converting liquid to solid heat is released by the system. Hence, enthalpy change, delta H is negative. A process becomes spontaneous only f its Gibbs energy is negative.
Here we have both negative entropy and enthalpy so make Gibbs energy negative higher temperature is needed.
Condensation of a substances is taking place at very low temperature and thus gibbs energy become positive. Therefore the process is nonspontaneous.
