Answer: Thus, scientists can look for similarities in the DNA and amino acid sequence to determine how closely related the two species are. The characteristics of an organism are determined by its genes, which are nothing but specific sequences of DNA molecules. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.

An example of an environmental trait is the coloring of flamingos. In the wild they eat shrimp cause if a reddish color true or false
Answer:
False
Explanation:
It's true that eating shrimp causes them to get pink, but that's an acquired trait, not an environmental trait.
An example of an environmental trait would be the changing of an animal's fur color by season
5. How is the heart (circulatory system of a frog different from a human heart?
Answer:
The circulatory system of a human compared to that of a frog is different due to the number of chambers. A frog’s heart has three chambers (two atria, and a single ventricle), whereas a human’s has four (two atria, and two ventricles). The atrium of a frog receives deoxygenated blood from the blood vessels that drain the various organs of the body. The left atrium receives oxygenated blood from the lungs and skin.

In a forest, gazelles were the main source of food for cheetahs. The gazelles depended on grasses and shrubs for their food. A mysterious disease quickly spread among the cheetahs, killing many of them. What impact would the decline of the cheetah population have on resource availability?
Because the number of cheetahs declined, the population of gazelles will most likely . This situation, in turn, will lead to increased between the gazelles and other herbivorous animals that eat the same food as gazelles.
Answer:
due to natural selection , if the predator of the gazelle declines, then the prey the gazelles will increase since there isn't many cheetahs killing them anymore.
the second should be competition, since there will be more gazelles needing to eat.

1. Give an example of a behavior you observed in another person. When you looked at
their behavior, did you decide their action was more a result of circumstances, or their
personality? What information did you use to make your judgment? (6 points)
(its psychology btw)
Answer and Explanation:
The person to whom I observed a behavior that will be exposed in this response was a character from a show called "Reply 1988." This character showed a highly explosive behavior and was very nervous and stressed. I believe that this behavior is a result of the circumstances that this character was experiencing at the time, as he was under a state of great tension and stress, as he believed that his son had suffered a plane crash. In addition, this character has always shown a very calm and peaceful personality throughout his life, which shows that the explosive behavior was caused by the circumstances. To make this judgment I used the way the character behaves in his daily life and his interactions with other characters.

Two forces are applied to the 45kg box as shown the box is smooth surface which statement best describes the acceleration of the box
Question: Two forces are applied to a 45 kg box, as shown. The box is on a smooth surface.Which statement best describes the acceleration of the box? Assuming the diagram is similar to the one attached.
A) The box accelerates at 1.0 m/s² to the right because the net force is 45 N to the right.
B) The box accelerates at 1.9 m/s² to the right because the greater force is to the right.
C) The box accelerates at 3.0 m/s² because the combined forces cause the box to accelerate.
D) The box does not accelerate, because neither force is large enough to move the box.
Answer:
A) The box accelerates at 1.0 m/s² to the right because the net force is 45 N to the right.
Explanation:
From the diagram attached,
F₂-F₁ = ma.................. Equation 1
Where F₂ = Force acting to the rigth, F₁ = Force acting to the left, m = mass of the box, a = acceleration of the box.
Make a the subject of the equation
a = (F₂-F₁)/m............... Equation 2
also from the diagram
Given: F₂ = 55 N, F₁ = 10 N, m = 45 kg.
Substitute these values into equation 2
a = (55-10)/45
a = 45/45
a = 1 m/s²
Hence the box accelerate at 1.0 m/s² to the right because the net force is 45 N to the right. Hence the right option is A.

takes place. Then cat runs
takes place inside the cat's body
Answer:
1. gravitational potential energy to kinetic energy
2. chemical energy to mechanical energy
Explanation:
i just took the test and got 100%
Gravitational force, potential energy to kinetic energy, and then conversion of chemical energy to mechanical energy take place in this order.
What do you mean by Prey?Prey may be defined as an animal that is hunted or killed by another animal for food.
When a cat drops from a tree to the ground follows the gravitational force, while the conversion of up behind a mouse to obtain its food is the process of converting potential energy to kinetic energy. And at last, after eating its prey, the conversion inside the cat's body takes place the chemical energy to mechanical energy.
Therefore, Gravitational force, potential energy to kinetic energy, and then conversion of chemical energy to mechanical energy take place in this order.

Which of these answer choices best describes the overall effects that would occur in an animal that consumes this plant?
Answer:
The majority of ATP will not form.
Explanation:
The poison leaf plant, also known as gifblaar contains fluoroacetic acid, a compound that shut down the Krebs cycle that leads to less production of ATP because Krebs cycle drives the formation of electron carriers. These electron carriers are very important because these electron carriers carry the energy that is used to create a large number of ATP molecules in the final steps of aerobic respiration so we can conclude that majority of ATP will not form due to poison.
How do photosynthesis and respiration work together to produce energy to support
life? How are the processes similar? How do the processes complement each other?
Photosynthesis and respiration work together by creating the energy and transporting it.
The process are similar because they both take something in, and let something else out.
The processes complement eachother by Respiration being able to take oxygen to the leaves, and the leaves using that oxygen to power their chemical reaction.

in the largest loss of energy that could otherwise be utilized by consumers?
A Movement
B. Homeostasis
C. Excretion
D. Respiration
Answer:
I think it is letter C
Explanation:
Correct me if I am wrong
The correct answer is option D. respiration as producers and other organisms of each trophic level most of their energy lose by metabolic reactions such as cellular respiration.
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat as energy flow from one organism to another trophic level are consumed by organisms from the next level.
only 10% of energy transfers to the next trophic level.Regulation of homeostasis of the organisms is also one of the ways an organism loses their energyExcretion or feces is also one of the ways organism lose their energyMost of their energy lose by metabolic reactions such as cellular respiration.
