Ashley is charting the motion of her pet rabbit. The diagram below shows its position every 0.25 seconds.
Which of the following statements about the rabbit's motion is true?
A. The rabbit's speed is increasing through time.
B. The rabbit is moving at a constant speed.
C. The rabbit's position is not changing through time.
D. The rabbit's speed is decreasing through time.
Answer:A
Explanation:
its is
The rabbit's speed is increasing over time, and it is known as velocity. Therefore, option A is correct.
What is velocity?Velocity is a term used in physics to describe the speed of an object in a particular direction. It is a vector quantity, which means it has both magnitude (speed) and direction.
The formula for calculating velocity is:
Velocity = displacement/time
In other words, velocity is often used interchangeably with speed, which is also a measure of how fast something is moving. However, velocity specifically refers to the speed of an object in a particular direction, whereas speed does not take direction into account.
Thus, The statement which is true about the rabbit's motion is "the rabbit's speed is increasing over time". Therefore, option A is correct.

Answer: 3. Structure is a better indicator of a relationship between two organisms because function can be caused by environment, not common ancestry. Structure is better than function because the structure is based on genetics. For example, the wings on a fly and the wings on a bird perform the same function, but their genetic bases are different. However, the wings on a bird and the arms on a primate are coded by similar genes even though the functions are different.
The best measure of relatedness is the underlying genomic DNA.
Explanation:
pesticides are chemicals that are often sprayed on crops to kill plant-eating insects, preventing damage to the crops. WHile pesticides are effective initially, many researchers claim that any single pesticide will see reduced effectiveness in as little as ten to fifteen years. Which of the following best supports the claim by scientists that the pesticides will eventually lose their effectiveness?
A. Insects will evolve to avoid any plant sprayed with pesticides to increase their chances of survival.
B. Insects that are naturally resistant to the pesticide will survive and reproduce more than the insects that are sensitive to the pesticide.
C. The insects will build up a tolerance to the pesticides, and eventually the pesticide will not affect them.
D. The pesticides will increase the mutation rate in the insects, resulting in higher genetic diversity and higher survival rate.
Pesticides will eventually lose their effectiveness as the pesticides will increase the rate of mutation in the insects, resulting in higher genetic diversity and higher survival rates. So, the correct option is D.
What are Pesticides?Any chemical or substance used for destroying the activity of insects or other organisms harmful to cultivated plants or to animals is known as pesticides.
It has been observed by scientists that the pesticides will eventually lose their effectiveness because pests have developed resistance - a significant decrease in sensitivity to a pesticide. The pesticide that is sprayed on crops allows increasing the mutation rate in the insects leads to increases in genetic diversity as well as their survival rate.
Therefore, Pesticides will eventually lose their effectiveness as the pesticides will increase the rate of mutation in the insects, resulting in higher genetic diversity and higher survival rates.

what is the relationship between transpiration and stomata
Answer:
Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.

D. oogenesis and cytoplasmic division
Answer:
A. nuclear duplication and cytoplasmic division
The two processes are involved in mitotic cell division include nuclear duplication and cytoplasm division.
Mitosis produces two identical daughter cells and is an asexual reproductive process which takes place during cell growth processes such as nuclear duplication and cytoplasm division.
Spermatogenesis and oogenesis are examples of sexual reproductive processes which involves the production of sperm and egg cells respectively. This makes them fall under meiosis and not mitosis.

A 10-micrometer cell is viewed through a 10x objective and a 10x eyepiece. How large will the cell appear to the microscope user?
Answer:
A 10x Eyepiece magnifies 10 times; in other words, an object viewed through the eyepiece, in focus, will seem ten times larger than normal. ... In this case, a 10x Eyepiece and a 10x Objective Lens would combine to show a 100x image, or an image 100 times the actual size.
Explanation:
If a 10-micrometer cell is viewed through a 10x objective and a 10x eyepiece, the cell will appear 100 times bigger than normal to the microscope user.
Magnification is defined as the ratio of the image distance to the object distance.
Magnification determines the number of times an image is larger or smaller than the object.
If the magnification is greater than 1, it means that the image is enlarged but if the magnification is less than 1, the image is a diminished image.
According to the question, if a 10-micrometer cell is viewed through a 10x objective and a 10x eyepiece, the total magnification will be:
M = Mo × Me
M = 10 × 10
M = 100
This shows that if a 10-micrometer cell is viewed through a 10x objective and a 10x eyepiece, the cell will appear 100 times bigger than normal to the microscope user.

Stromatolites contributed oxygen to the early atmosphere through photosynthesis.
What are stromatolites ?Stromatolites are layered sedimentary formations that are created mainly by photosynthetic microorganisms such as cyanobacteria, sulfate-reducing bacteria, etc. that lives today in a wide range of environments ranging from the shallow shelf to lakes, rivers, and even soils.
Cyanobacteria were ultimately responsible for one of the most important global changes that the Earth has undergone. Being photosynthetic, cyanobacteria produce oxygen as a by-product.

Earlier, you read how a bedroom could be used to help someone make a connection to a cell maintaining homeostasis. The door to the room was compared with the cell membrane, and the trash can was said to be like the vacuole that stores wastes in the cell, helping you understand the functions of these organelles.
Now, think of another object that could be compared with a cell. Using the space below, be creative as you explain how cellular respiration, diffusion, and waste removal take place in both the cell and the thing to which you are comparing it.
Answer:
Explanation:
years ago. Homeostasis ensures that cells can obtain and use energy, make new cells, . biology biology active answer key chapter 5 5 reading work homeostasis and cell.
Another object that could be compared with a cell is a Car. cellular respiration, diffusion, and waste removal take place in both the cell and the car.
A car can be compared to a cell in the following ways:The metal body of a car maintains its shape even at high speeds. In terms of structure, its body is similar to a cell wall. In that they protect the interior of the car from intruders such as insects and dirt, the windshield and windows are analogous to plasma membranes. Cars require power to drive, which is generated when fuel is converted to energy in the engine, much how mitochondria produce ATP. The endoplasmic reticulum aids in material transport in cells, and the fuel line transports fuel from the gas tank to the engine in automobiles. The nucleus of a cell is analogous to the driver of a car. If the driver does not press the gas pedal, the automobile will not move.The gas pedal communicates the driver's intention to proceed to the engine, exactly as a ribosome does with information from the nucleus. When a car's engine burns fuel, it produces exhaust, which is passed through a catalytic converter before exiting the vehicle to reduce pollution. The Golgi apparatus, like the catalytic converter, does its own material packaging for transportation. Like vacuoles in cells, the automobile trunk and glove box serve as storage chambers.hence this is how a car is similar to a cell
