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.
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.

When a cat drops from a tree to the ground, the conversion of

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.

A community is concerned that its river has become polluted. Analysis of
water samples shows small amounts of over 20 different chemicals.
Which of the following is the most likely cause for the increase in
pollution?
A
The increase is due to agricultural point source pollution.
B
The increase is due to industrial point source pollution.
C
The increase is due to residential non-point source pollution.
D
It is impossible to determine.
erale Learning Inc. - All Rights Reserved
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.

harvested by plankton is passed to the primary consumers. Which process in phytoplankton results
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.

contributes to this complex problem?
A. Conserving Earth's limited fossil fuel reserves
B. Mitigating problems associated with rising sea
levels
W
C. Reducing global emissions of greenhouse gases
D. Developing efficient ways of transporting food
Answer:
developing effient ways of transporting food
Explanation:
The correct answer is option D. Developing efficient ways of transporting food can help solve the problems.
What does the problem address ?This problem directly addresses the issue of how to transport food effectively over long distances, which is a contributing factor to the spoilage of produce in Chinese agricultural regions.
By finding more efficient ways to transport the produce, such as better refrigeration systems or more direct routes to markets, less food will spoil and go to waste.
Therefore, by conserving Earth's limited fossil fuel reserves, mitigating problems associated with rising sea levels, and reducing global emissions of greenhouse gases may be important issues in their own right, but they are not directly related to the problem of food spoilage during transportation.
