A plant would respond positively to gravity if a light source was placed below a plant.
TROPISM:
Tropism is the movement of a plant or part of a plant in response to stimulus (light, heat, water). A plant's response to light is called phototropism while plants response to gravity is called geotropism. Ideally, a plant's shoot is positively phototropic while a plant's root is positively geotropic. Hence, if a light source is placed under a plant, the plant would respond positively to gravity.Learn more at: https://brainly.com/question/10942902?referrer=searchResults
Examine the picture of an onion root tip with cells in various stages of the cell cycle. A student claims that interphase is the longest stage of the cell cycle. Another student claims that mitosis is the longest stage. Using evidence from the photo, determine which student is correct and why. A) Mitosis is the longest stage because anaphase requires more time to separate chromatids. B) Interphase is the longest stage because chromosomes are visible in the majority of the cells. C) Mitosis is the longest stage because the majority of the cells in the photo are replicating their DNA. D) Interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing.
Answer:
B
Explanation:
the longest phase in the cell division is interphase because the DNA replication occurs in this phase
As per the image interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing. The correct option is D.
What is cell cycle?The cell cycle, also known as the cell-division cycle, is the sequence of events that occurs in a cell that causes it to divide into two daughter cells.
A cell cycle is the series of events that takes place in a cell as it grows as well as divides.
A cell spends the majority of its time in what is known as interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.
Interphase is the longest stage, according to the image, since the maximum of the cells in the photo have uncondensed chromatin as well as are not dividing.
Thus, the correct option is D.

The flow of energy moves in a circle through a food chain. The energy moves from the grass to the grasshopper. Next, the transfer of energy passes from the snake to the hawk. Finally, the fungi help by breaking down the hawk when it dies, and returns the energy to the grass. Where does the energy that is transferred through this chain originate? A) fungi B) grass C) grasshopper D) sun
Answer:
i think it is B grass
Explanation:
Grass obtains energy through the use of photosynthesis. Chlorophyll absorbs sunlight and uses its energy to convert carbon dioxide and water into carbohydrates.

In fruit flies, the gene for eye color is located on the X chromosome, and the red eye allele (R) is dominant
to the white eye allele (r). A carrier female is mated with a male fly with genotype X
rY. Which of the
following statements best describes the expected outcome of the cross?
a. The chance of an offspring having red eyes is 75%
b. The chance of an offspring having white eyes is 50%
c. The chance that a male offspring will have white eyes is 0%
d. The chance that a female offspring will have red eyes is 100%
Answer:
b. The chance of an offspring having white eyes is 50%
Explanation:
So the genotype of the male fly is X^r Y. This means the male has white eyes because he only has one X chromosome, so he will express whatever allele is on that chromosome.
The genotype of the female fly, though, is X^R X^r. This is because carriers are heterozygous for traits, and the sex chromosomes of most females is XX (with some exceptions, like XXX, or X (Turner syndrome)).
If we cross this, what are the outcomes? Do a Punnett square. You get the genotypes of X^r X^R, X^r X^r, X^R Y, and X^r Y. The expected phenotypes are a red eye female, white eye female, red eye male, and white eye male.
Now, let's look at the choices:
A.: The chance of an offspring having red eyes is not 75%; it is 50%.
B.: The chance of an offspring having white eyes is 50%!!!
C.: The chance that a male offspring will have white eyes is 50%, not 0%.
D.: The chance that a male offspring will have white eyes is 50%, not 100%.

Which best describes this excerpt?
Read the excerpt from "A Simple Way to Create Suspense".
For instance, heading toward a movie review program,
remember we asked: Who was the studio's first choice for
the Harry Callahan role in "Dirty Harry"?
We knew most viewers would be intrigued. (What, Clint
Eastwood wasn't the first choice?) But—and this was the
lesson—the success of the tactic didn't depend on intrigue.
Even viewers with no interest at all stuck around to find out.
Humans are hard-wired. They need to know. Even viewers
who knew the answer for sure stuck around, in order to be
gratified. The gap was bridged, and the danger averted. (It
was Frank Sinatra. You waited, right?)
O The central idea of this excerpt is that Clint Eastwood was
not the original choice for the Dirty Harry movie.
O The central idea of this excerpt is that intrigue is the most
important way to create suspense.
O The author uses an analogy to compare his readers to the
characters of a Hollywood movie.
O The author uses a personal anecdote to show that
audiences are willing to wait for an answer.
