The pressure in mmHg of a 0.025 mole sample of CO2 at 350 k in a 2.00L container is 273.6 mmHg.
How to calculate pressure?The pressure of a gas can be calculated using the following expression:
PV = nRT
Where;
P = pressureV = volumen = number of molesR = gas law constantT = temperatureP × 2 = 0.025 × 0.0821 × 350
2P = 0.72
P = 0.72/2 = 0.36atm
Therefore, the pressure in mmHg of a 0.025 mole sample of CO2 at 350 k in a 2.00L container is 273.6 mmHg.

How can we see the object?Organisms adapted and evolved the eyes to see the surrounding environment. This ability to see begins when the visible wavelength of light enters the eye through a transparent covering called Cornea. The light enters the cornea and enters the inner of the eye through a round hole known as the pupil.
The light rays then enter the convex-shaped lens in the eye which focuses the beam of light on the back of the eye in the region of the tissue called the retina. The retina contains the photoreceptor cells-rods and cones in which the cone cells have the ability to detect three wavelengths of light especially blue, green and red which help us see various versions of the colour.
These cells convert light energy to chemical energy in the form of the action potential which gets transmitted to the part of the brain associated with the vision. This completes the pathway of the vision.
Thus, Retina is the answer.

Carbon fixation occurs in the second stage of photosynthesis, during the light-independent reactions of the Calvin cycle. In the first step of this cycle, the enzyme Rubisco adds CO2 to the energy-rich compound ribulose 1,5-bisphosphate, ultimately producing two molecules of 3-phosphoglycerate. In a culture of green alga that is carrying out photosynthesis in the presence of CO2 in the laboratory, what would happen to the levels of ribulose 1,5-bisphosphate and 3-phosphoglycerate in the minutes after the lights were turned off and the cultures were plunged into darkness
Ribulose 1,5-biphosphate will be depleted while 3-phosphoglycerate will accumulate.
Carbon fixationThe first step of the carbon fixation during which Rubisco adds CO2 to Ribulose 1,5-biphosphate to produce 2 molecules of 3-phosphoglycerate requires energy molecules from the light reaction.
In the subsequent steps, Ribulose 1,5-biphosphate is regenerated in a step that requires energy molecules from the light reaction.
Thus, in the first few minutes of turning off the light, the available energy molecule from the light reaction will be used up to produce 3-phosphoglycerate. However, the regeneration of Ribulose 1,5-biphosphate will become impossible.

which component is released from the active site of an enzyme during a chemical reaction ?
Answer:
The Product
Explanation:
In a chemical reaction the enzyme plays an important role in catalyzing the reaction.
The enzyme has an active site on its structure to which a substrate can come and bind. The active site has a specific shape to which the substrate of complementary shape can come and bind. once the substrate is bound to the active site of the enzyme the reaction takes place and a product is formed. Once the product is formed, product is released from the active site and enzyme remains unchanged at the end of the reaction.
therefore answer is product that is released from the active site

How does cladistics reconstruct phylogenies?
Cladistics reconstructs phylogenies by considering shared derived characters between taxonomic groups and the maximum parsimony criterium.
What is the cladistic analysis?Cladistics evaluate the relationship between different taxa according to shared characters.
The cladistic analysis follows the maximum parsimony criterium.
Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes.
It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.
The sequencing term refers to lists of groups according to their relationship and their shared traits. One group is the sister group of the following one.
Cladistics uses cladograms to represent the common ancestral relationships and the emergence of different characters among the involved groups.
So the cladogram represents the relationship between taxonomic groups according to a derived character.
The derived character is any new trait that a group transmits to its descendants.
Through evolution, the characters change, and new changes are added. When referring to a derived character, we mean that all the subsequent groups in the cladogram carry and share the trait.
According to this framework, cladistics reconstructs phylogenies by considering shared derived characters and the maximum parsimony criterium.

Answer : (A) "It reflects waves off of objects, measuring the difference of the waves it sends and receives".
Explanation :
In Doppler radar system, radio waves emitted from an antenna. It gives information about the motion of targets and their position.
Phase change between a transmitted wave and received echo is calculated using Doppler radar system.
It also gives radial velocity i.e. velocity in the direction of radar. If the phase shift is positive this means the motion is toward the radar and if the phase is negative this implies the motion is away from the radar.
So, the correct option is (A) "It reflects waves off of objects, measuring the difference of the waves it sends and receives".
