The correct statement is: The stages of development of the embryos of different organisms are extremely similar, thereby suggesting common ancestors.
Comparing the embryos of different organisms supports the theory of evolution because it reveals striking similarities in their early stages of development. These similarities suggest a common ancestry or shared evolutionary history among different species. In many cases, embryos of different organisms exhibit similar structures and developmental processes during their early stages, even if they later develop into different adult forms. For example, the embryos of vertebrates, including humans, fish, birds, and reptiles, share common developmental features such as the presence of gill slits and tails during early stages. This suggests that these organisms share a common ancestor that possessed these characteristics. By comparing embryos, scientists can observe and analyze these shared developmental patterns and use them as evidence for common descent and evolutionary relationships among different species. This supports the idea that all organisms are connected through a complex web of evolutionary history and share a common origin.

Large seeds would have the most difficulty being dispersed by:.
Large seeds would have the most difficulty being dispersed by water dispersal, option (c) is correct.
Water dispersal is generally more effective for small, lightweight seeds that can float or be carried away by water currents. Large seeds, on the other hand, are often heavy and less buoyant, making it difficult for them to be carried away by water. They may sink or become lodged in the sediment, limiting their ability to disperse and colonize new areas.
In contrast, mechanical dispersal, wind dispersal, and animal dispersal can be more suitable for large seeds. Mechanical dispersal involves the physical ejection of seeds from the plant, wind dispersal relies on air currents to carry lightweight seeds over long distances, and animal dispersal occurs when animals ingest seeds and later excrete them, aiding in their dispersal, option (c) is correct.

How big would a 2 micrometer cell appear under each objective lens in the compound microscope?
The size of a 2-micrometer cell would appear differently under different objective lenses in a compound microscope.
The magnification of a compound microscope is determined by the combination of the objective lens and the eyepiece. Each objective lens has a specific magnification power, typically indicated on the lens. The total magnification is calculated by multiplying the magnification of the objective lens with that of the eyepiece. For example, if the objective lens has a magnification of 10x and the eyepiece has a magnification of 10x, the total magnification would be 100x (10x objective lens * 10x eyepiece). This means that the 2-micrometer cell would appear 100 times larger, making it appear as 200 micrometers .

Knowing that the frequency of the folded ears genotype ff is equal to to the frequency of the f allele squared (0.1 x 0.1), how many cats would have folded ears if after 10 generations there are 2,500 cats on the island?
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%.

How is a prime mover different from a synergist muscle.
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.

4. In cellular respiration, the energy stored in glucose molecules is released and
stored in what energy-rich molecule (the cell's charged battery) that cells use to
do work?
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.

A water tank is draining. The volume of the water in the tank, in gallons, is a linear function of the amount of time it has been draining, in hours. It can be modeled using the equation V (t) = –12. 8t + 685, where V is the volume and t is the time. Explain what the values -12. 8 and 685 mean in the context of this problem. Be sure to use units in your response.
In the given equation V(t) = -12.8t + 685, the value -12.8 represents the rate at which the volume of water in the tank is decreasing per hour. The value 685 represents the initial volume of water in the tank when the draining process started.
In the equation V(t) = -12.8t + 685, the coefficient -12.8 indicates the rate of change of the volume with respect to time. It represents the slope of the linear function, indicating that the volume of water is decreasing by 12.8 gallons per hour. This negative value indicates that the volume is decreasing over time as the tank is draining.
The constant term 685 represents the initial volume of water in the tank when the draining process began. It indicates the volume of water in the tank at t = 0 hours. In this case, it implies that at the start of the draining process, the tank contained 685 gallons of water.
