Answer:
Chromosomes contain genes, which help to determine an organism's traits. Genes come in alternate forms called alleles. The actual gene combination that an organism receives from its parents is called its genotype, while the trait that gets expressed as a result is referred to as its phenotype. If an offspring receives the same type of allele for a given gene from each parent, it is said to be h o m o z y g o u s. If the alleles differ, it is h e t e r o z y g o u s.

Answers
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.

Hunting and Gathering
Explanation:
The first humans were nomads who traveled with their food. This means that they would seasonally move across regions hunting the animals there and gathering plants to eat. These people existed before civilization started. Centuries later, these people would develop agriculture and start society. However, the first people were still hunter-gathers.
During meiosis, homologous chromosomes line up next to each other. In some
cases, one arm of a chromatid crosses over the arm of another chromatid. What is
the result of this process?
the independent assortment of genetic material
the creation of an additional sex cell
continuity in the offspring cell's DNA
additional variation in the DNA of each sex cell formed
Answers
This is known as Crossing Over and results in further variation in offspring
Crossing over is a mechanisms involved in introducing genetic variation. When the arm of a chromatid crosses over the arm of another chromatid, it results in additional variation in the DNA of each sex cell formed. Option D.
---------------------------------------
Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.
The Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.
The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.
After crossing over, homologous chromosomes get separated again.
So, according to this information, when the arm of a chromatid crosses over the arm of another chromatid, it results in additional variation in the DNA of each sex cell formed.

Answer:
B. The increase is due to industrial point source pollution.
Explanation:
Pollution is the release of harmful substances into land, air or water. The harmful or toxic substances are called POLLUTANTS. According to this question, a community discovers via analysis that its river is now polluted with small amounts of over 20 different chemicals.
This chemicals is a pollutant that can likely emanate from industrial companies and industries that produces these harmful chemicals as waste. Hence, the increase is due to industrial point source pollution.

Two forces are applied to the 45kg box as shown the box is smooth surface which statement best describes the acceleration of the box
Answers
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.

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.

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.
Answers
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)
Answers
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.

Answers
In this scenario, natural selection is affecting many populations of birds with different beak morphologies, which affects how well they can eat the available foods. Each flock initially consisted of 10 birds, but over many generations, natural selection favored some traits over others, changing the population size.
One flock, referred to as "Flock," had the greatest number of second-generation birds because it was the most successful at feeding. Another flock, known as "Flock," had the worst feeding results and has had the greatest shrinkage.

Your question is incomplete, most probably the complete question is:
The flocks all started with 10 birds. Flock was the most successful at feeding, so it will have the greatest number in the second generation. Flock was the least successful at feeding and has shrunk the most. With three foods available, natural selection has favored Flock , which has increased the most in the first three generations. Meanwhile, Flock has declined the most because its beak was the least successful phenotype for the food available.
