The energy stored in glucose molecules during cellular respiration is released and stored in adenosine triphosphate (ATP), which serves as the cell's energy currency.

During cellular respiration, glucose molecules are broken down through a series of biochemical reactions, such as glycolysis, the Krebs cycle, and oxidative phosphorylation. These processes extract energy from glucose and transfer it to ATP molecules.
ATP is composed of three phosphate groups, ribose (a sugar molecule), and adenine (a nitrogenous base). The energy released during the breakdown of glucose is used to add a phosphate group to adenosine diphosphate (ADP), converting it into ATP. This process, called phosphorylation, stores energy in the high-energy phosphate bonds of ATP.
ATP acts as the cell's primary energy carrier and serves as a "charged battery" that can be readily used to perform various cellular functions. When a cell requires energy to carry out work, ATP is hydrolyzed by removing one phosphate group, releasing energy and forming adenosine diphosphate (ADP) and inorganic phosphate (Pi). This energy can be used for processes such as active transport, muscle contraction, synthesis of macromolecules, and other cellular activities.
In summary, ATP is the energy-rich molecule that cells use to store and release energy obtained from the breakdown of glucose during cellular respiration. It provides the necessary energy for cellular processes and serves as a crucial component in energy transfer within cells.

The changes in the egg's mass can be explained in terms of osmosis. Osmosis is the movement of solvent molecules (in this case, water) across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

In the context of the egg experiment, the egg is submerged in different solutions of varying concentrations. The eggshell acts as a semi-permeable membrane, allowing water molecules to pass through but restricting the passage of solutes. When the egg is placed in a hypertonic solution (a solution with a higher solute concentration compared to the egg's interior), water molecules move out of the egg through the shell by osmosis. This results in a net loss of water from the egg, causing it to lose mass. Conversely, when the egg is placed in a hypotonic solution (a solution with a lower solute concentration compared to the egg's interior), water molecules move into the egg through the shell by osmosis. This leads to a net gain of water, causing the egg to gain mass.

There are 25 cats with folded ears genotype if after 10 generation there are 2,500 cats.

The frequency of the folded ears genotype f.

f is equal to the frequency of the f allele squared (0.1 x 0.1).

There are 2 ways to solve this problem:

1. Using the Hardy-Weinberg equation:

p² + 2pq + q² = 11,

where p is the frequency of the dominant allele F, q is the frequency of the recessive allele f, p + q = 1, and 11 is the total number of cats.

Since the frequency of the f allele squared is 0.1 x 0.1 = 0.01, q² = 0.01.

Thus, q = √0.01 = 0.1.

Therefore, p = 0.9.

The number of cats with the f

f genotype is q² x 11 = 0.01 x 2,500

= 25 cats.

2. Using the frequency of the f

f genotype:

Since the frequency of the f

f genotype is equal to the frequency of the f allele squared, the frequency of the f

f genotype is 0.01, or 1%.

A prime mover and a synergist muscle are two distinct types of muscles that work together to facilitate movement, but they have different roles and functions.

A prime mover, also known as an agonist muscle, is primarily responsible for producing a specific movement. It is the main muscle that contracts to initiate and carry out the desired action. The prime mover generates the majority of the force required to perform a particular movement. For example, during the quadriceps extend the knee during leg extension exercise, the quadriceps femoris muscle acts as the prime mover.
On the other hand, a synergist muscle assists the prime mover in performing a movement but does not directly contribute to the main action. Synergist muscles work in coordination with the prime mover to stabilize joints, provide additional support, or modify the direction of the movement. They help to control the movement and improve its efficiency. For example, during the bicep curl exercise, the brachialis muscle acts as a synergist, assisting the biceps brachii in elbow flexion.
