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

Answers

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 energy

Most of their energy lose by metabolic reactions such as cellular respiration.

How will distinguish between natural and artificial fibres by observing the smell produced when burnt?​

its not biology it's chemistry

Answers

Answer:

Natural fiber smell like paper whereas artificial fiber smells like an acid.

Explanation:

We can distinguish between natural and artificial fibers by observing the smell produced when burnt because both produces different types of smell when burnt. When the artificial fibers are burn, it produces acid or chemical like odor and leaving a plastic like bead while on the other hand, when the natural fiber burn, it produces smell of burning paper or hair and leaving ash of soft and grey colour. Natural organic fibers burn rapidly with a yellow flame.

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.

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.

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

Additional variation in the DNA of each sex cell formed

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.

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.

Which of these answer choices best describes the overall effects that would occur in an animal that consumes this plant?

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.
