Answer:
B. It is a reflex response that causes various muscles to contract in order to move away from the object.
Explanation:
I just took the Test
It is a reflex response that causes various muscles to contract in order to move away from the object. Therefore, option (B) is correct.
What is reflex response?A reflex response is an automatic, involuntary response to a stimulus that does not involve the conscious part of the brain. In this case, the reflex response causes various muscles to contract in order to move away from the sharp object, which helps to minimize further injury. Reflexes are a protective mechanism that can operate without the need for conscious control or decision making.
The reflex response described in this scenario is not a learned response, a conditioned response, or a voluntary response. It is an innate, automatic response that occurs in response to a specific stimulus, and it occurs in both infants and adults.

Vacuoles are cellular organelles that are found in all plant and fungal cells. In plant cells, vacuoles tend to store large amounts of water, so they can push outward on cell walls and help keep plants upright. In fungal cells, vacuoles often store materials that are toxic to the cell.
According to the above information, how do vacuoles help fungal cells maintain homeostasis?
A.
by storing large quantities of water
B.
by allowing the cells to get rid of waste
C.
by producing more cellular organelles
D.
by helping the cells extract energy from food
Answer:
D. by helping the cells extract energy from food
Explanation:
Fungi are decomposers so they normally need some sort of food to grow. To get the energy to grow, they extract it from the food. Fungi will get their energy from dead animals, dead plants, etc.
The primers you used in lab amplified 145 base pairs that were adjacent, but not included in the repeat. If you used a different primer that only amplified 130 base pairs adjacent to a 14 base pair repeat, and you had 4 repeats in your product, what was the size of your final PCR product?
186
214
158
200
172
Answer:
186
Explanation:
The Polymerase Chain Reaction (PCR) is a technique used in molecular biology to amplify small segments of DNA. This technique uses a pair of oligonucleotide sequences called 'primers' which bind to opposite strands of the heat-denatured DNA template in order to amplify this target DNA sequence. In this case, the DNA template is composed of a single unit of 130 base pairs (bp) and four repetitive units of 14 bp, so the final PCR product will have 186 bp >>> 130 bp + (14 bp x 4) = 130 + 56 = 186.

The law of conservation of energy states that energy cannon be created or destroyed.
O True
O False
Answer:
false
Explanation:
The first law of thermodynamics, also known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. For example, turning on a light would seem to produce energy; however, it is electrical energy that is converted.

How do toothed whales produce echolocating sounds?
Answer:
As the lips vibrate, the sound is transmitted via the whale's 'melon' – fatty tissue that makes up its forehead. This tissue has the same acoustic properties as water. ... Toothed whales can direct sound by bouncing it off air sacs in their nose and possibly by using face muscles to alter the shape of the melon.
Explanation:
15. Cells found in plants and animals have similarities but can differ in function. Consider the following two organisms: a corn plant cell (Zea mays) and a camel cell (Bactrianus ferus). What is the best explanation for the difference in the cellular vacuole size between these two biotic organisms?
A. The corn cells' have a small vacuole size because it does not need long term water and
electrolyte storage.
B. The camel cells' have a small vacuole size because it does not need long term water and electrolyte storage.
C. The camel cells' have a small vacuole size because it is not in contact with toxins that need to be removed from the cell.
D. The corn cells' have a large vacuole size because it is in contact with many toxins in the soil which need to be removed from the cell.
The best explanation for the difference in the cellular vacuole size is option d. The corn cells' have a large vacuole size.
Explanation to the difference in the cellular vacuole size:When there is the difference in the vacuole size that lies between the two biotic organism so it is due to the corn cells that contain high vacuole since they are in contact with various toxins in the soil that need to be eliminated from the cell.
hence, the correct option is d.
And, the rest of the options are wrong.

Which of the following effects is least likely to be as a result of deforestation?
A: A greater risk of flooding.
B: An increase in biodiversity.
C: An increase in soil erosion.
D: An increase in the level of carbon dioxide in the atmosphere.
The effect that is least likely to be a result of deforestation is an increase in biodiversity. That is option B.
Deforestation is a practice that encourages the clearing of forests for other purposes such as agricultural croplands, urbanization, or mining activities.
This practice needs to be avoided because:
posses a greater risk of flooding as deforestation erodes the soil.they provide a protective cover for the soil against the action of wind and rain thereby preventing soil erosion.the level of carbon dioxide in the atmosphere decreases as it is cleared by trees during photosynthesis.But deforestation leads to a decrease in biodiversity instead of an increase.
Deforestation can lead to biodiversity loss. This occurs when animal species that live in the trees no longer have their habitat, cannot relocate, and therefore become extinct.

How do toothed whales produce general communication sounds?
Answer:Toothed whales do not make the long, low-frequency sounds known as the whale song. Instead they produce rapid bursts of high-frequency clicks and whistles. Single clicks are generally used for echolocation whereas collections of clicks and whistles are used for communication.
Which of the following is NOT a correct base pair?
A-C
T-A
C-G
A-T
Answer:
A-C
Explanation:
Hello There!
Remember these are the complementary base pairs
Adenine and Thymine (so the 2nd and 4th one are correct base pairs)
Cytosine and Guanine ( so the 3rd one is a correct base pair)
Hence, A-C would be the incorrect base pair because like stated previously Adenine pairs with thymine not cytosine

Answer:
A nerve is formed by a bundle of many neurons. Neurons develop from the neural tube of the early embryo and in many animals continue development until sometime after birth. The development of motor neurons that have elongated axons is best understood. These cells are derived from tissue on the ventral side of the neural tube.

Once anything passes through the event horizon, from the perspective of that
object, nothing would change.
True or false
Answer:
True
Explanation:
The event horizon of a black hole is where gravity is such that not even light can escape. This is also the point I understand that according to Einstein time dilation will be infinite for a far-away-observer.
The statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.
What is horizon?The horizon would be the line that appears to divide a celestial body's ground from its own sky when observed by an observer standing on or close to the body's surface.
What is event?An event would be the collection of results from an experiment.
Therefore, the statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.
