Victor put a match on a balance and found that its mass was 6.0 grams. Then he lit the match and put it out after a few seconds.



He put the partially burned match on the balance again. This time, its mass was 4.5 grams.

Which of the following best explains what happened as the match burned?
A.
Some of the mass was destroyed by the fire.
B.
The mass of the match combined with the mass of the fire.
C.
The matter moved to a different part of the match.
D.
Some of the matter changed from solid to gas and went into the air.

Answers

Answer: It releases oxygen and heat. The answer is C

Stored inside the match head is another chemical called “potassium chlorate”. When it gets hot, it releases a lot of extra oxygen and heat. This makes the match head burn quickly and strongly. When you put it all together the heat, the fuel, and the oxygen  you get a flame. Matter does not go when something is set on fire. Matter is always the same.  Burning is a chemical process. The flames are caused as a result of a fuel undergoing combustion (burning). (CC BY-SA 2.5; Einar Helland Berger for fire and Walter Siegmund for ash).

For many years, scientists thought that the universe was static—that it had always existed and been the same, and it was neither expanding nor contracting. Then, in the late 1920s, Edwin Hubble recognized that the shift in light from distant objects toward the red end of the spectrum meant that those objects were moving away from Earth. The best explanation for these observations was that the universe was not static but was expanding. More recent observations, such as cosmic background radiation, are also better explained by an expanding universe rather than a static universe. What aspect of scientific methodology best explains the replacement of the static universe theory with the expanding universe theory?
A Science and its methods are always improving. Scientists needed newer, more sensitive instruments to detect the slow expansion of the universe.

B Hubble’s observations were extremely popular with the public, leading to overwhelming support for the new theory.

C The new theory explained Hubble’s observations, and it was tested and supported by additional observations. The theory was accepted because it was the most powerful explanation available for many observations.

D The natural progression of science is that all theories are eventually replaced by new theories until one is established as law

Answers

Answer:

C

Explanation:

B has nothing to do with the scientific method. The public does not determine a scientific law. Facts do.

D may be sort of true, but it does not explain Hubble's process. Nor does it explain what Hubble actually did and how he reported it. D is incorrect.

A was never implied (although it is likely true. On the other hand, many great scientific principles are uncovered with very simple apparatus.) A might be 1/2 true.

I think the best answer is C. It is general enough to be accepted. There are two theories mentioned. So C is the best answer.

Which statement best distinguishes aerobic from anaerobic respiration?
A. Only aerobic respiration involves fermentation.
B. Only anaerobic respiration occurs in the mitochondria.
C. Only aerobic respiration requires oxygen.
D. Only anaerobic respiration produces carbon dioxide.

Answers

Answer:

C. Aerobic respiration

Explanation:

Aerobic respiration occurs when oxygen is present

Anaerobic respiration occurs in the absence of oxygen. Anaerobic respiration is usually associated with fermentation process (eg Alchohol production)

The main difference between aerobic and anaerobic respiration is that aerobic respiration needs oxygen to occur, while anaerobic respiration does not. Option C. Only aerobic respiration requires oxygen.

What is cellular respiration?

Aerobic and anaerobic respiration occurrence depends on the presence or absence of oxygen. Option C. Only aerobic respiration requires oxygen.

Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.

What is Aerobic Respiration?

This type of respiration occurs in the presence of free oxygen. It involves a series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.

Aerobic Respiration occurs in mitochondria, and takes place in two steps or stages: Krebs cycle and electron transporter chain.

Glycolysis and Krebs cycle produce electrons. These electrons then travel along the electron transporter chain while releasing energy, and ATP is produced.

What is Anaerobic Respiration?

This is the type of respiration that occurs in the absence of free oxygen.

It is also a series of reactions by which the cell produces 2 ATP molecules by using pyruvate (product of glycolysis).

Anaerobic respiration can occur in two ways: lactic fermentation and alcoholic fermentation.

Lactic fermentation produces lactic acid and 2 ATPAlcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂

The whole anaerobic process occurs outside the mitochondria.

Options:

A). Only aerobic respiration involves fermentation. FALSE.

Anaerobic respiration involves fermentation.

B). Only anaerobic respiration occurs in the mitochondria. FALSE.

Aerobic respiration occcurs in mitochondria and anaerobic respiration occurs in the cytoplasm.

C). Only aerobic respiration requires oxygen. TRUE

Anaerobic respiration does not need oxygen.

D). Only anaerobic respiration produces carbon dioxide. FALSE

Alcoholic fermentation produces CO₂ too.

The correct option is C. Only aerobic respiration requires oxygen.

Answers

Answer: A or D

Explanation:

In the early 1900s, three species of goatsbeard wildflowers, T. dubius, T pratensis, and T. porrifolius, were introduced to the United States. Each of the species had a chromosome number of 2N. In the 1930’s, a few populations of offspring from the original wildflowers were identified as having a chromosome number 4N. What does this data suggest about speciation.
A. Speciation has occurred because the original species of wildflowers produced populations of viable offspring.
B. Speciation has occurred because breeding between the offspring and original populations would not be possible.
C. Speciation has not occurred because the offspring of the original wildflowers were not introduced into a new area.
D. Speciation has not occurred because the offspring inherited identical genetic information to the original wildflowers.

Answers

Answer:

B. Speciation has occurred because breeding between the offspring and original populations would not be possible.

Explanation:

Speciation has occurred in the species due to no breeding between the offspring and original populations because the offspring and original species has different number of chromosomes in their DNA. Due to this difference in the chromosome number in the DNA, there is no chance of breeding between offspring and original species. Speciation is the evolutionary process by which populations of organism evolve with the passage of time and become different from the original species.

Why do you think there are so many bones in the cranium? Why do you think we are born with separate cranial bones that later fuse together as we grow and develop?

Answers

Hi, rachellelunaa!!

I think the reason we have so many bones is because, firstly, the cranium is such a unique shape that we need multiple bones to form it. Also, another reason we are born with separate cranial bones is that when a baby is born, there is an incredible amount of pressure being administered to the baby during the process. The many unfused bones allow the child's head to be malleable, and therefore preventing damage to the skull and brain. As we grow, we no longer need these bones to be malleable and they fuse together.

I really hope this answers your question!!

The sutures are flexible, the bones can overlap during birthing, preventing the baby's head from pressing against the baby's brain and causing damage.

What are the cranial bones?

Skeletal structure of the head. The cranium, which surrounds and protects the brain, is made up of cranial bones and facial bones (bones that form the eye sockets, nose, cheeks, jaw, and other parts of the face).

The two remaining cranial bones are covered by the frontal bone. The sphenoid bone and ethmoid bone are these.

Behind your eye sockets, the sphenoid bone supports the muscles of your face. At the peak of your nose, between your eye sockets, is the ethmoid bone.

Therefore, preventing damage to skull and brain, we are born with separate cranial bones.
