Which of the following is an example of aerobic respiration? A.Lactic acid fermentation in human muscles B.Physical exchange of gases in human lungs C.Respiration during vigorous physical exercise D.Breaking down of glucose with oxygen inside an animal cell

Answers

Since Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor . therefore Only D !

D. Breaking down of glucose with oxygen inside an animal cell is an example of aerobic respiration.

Lactic acid fermentation occurs in human muscles and it is not a type of aerobic respiration as it occurs in the absence of oxygen gas. In this process, lactate or lactic acid is produced by the glucose. Physical exchange of gases in human lungs is called breathing. Respiration during vigorous physical exercise is an example of anaerobic respiration because vigorous physical exercise creates deficiency of oxygen. Aerobic respiration is a type of cellular respiration in which the glucose is broken down to release energy in the form of ATP or adenosine triphosphate in the presence of oxygen. This type of respiration occurs in both animal and plant cells. Hence, breaking down of glucose with oxygen inside an animal cell is an example of aerobic respiration.

Why are viruses considered to be nonliving?


A. They have no genetic material.


B. They cannot reproduce without a host cell.


C. They do not respond to their environment.'


D. They cannot use energy.

Answers

Answer:

B. They cannot reproduce without a host cell.

It is considered to be nonliving as it cannot reproduce on its own.

Explanation:

Without a host cell they are unable to reproduce as it does not have the necessary reproductive tools.

It reproduces by using the host cell's reproductive tools by taking control of it.

Viruses also don't need energy as living organisms do. So the answer may be D. as well.

Viruses are considered to be non-living because they cannot reproduce without a host cell.

WHAT ARE VIRUSES?

Viruses are organisms that are incapable of reproducing without a living host.

Viruses can only make use of the mechanism of a living host, which they infect.

Viruses are structurally made up of a genetic material and a protein capsule.

Therefore, it can be said that viruses are considered to be non-living because they cannot reproduce without a host cell.

An object of the same mass has three different weights at different times. Which statement is possible? The object gains matter and then loses it. The object started on Earth, was transported to space, and was deposited on the moon. The object started at the bottom of a hill, then moved to the top of the hill, and then moved back down to the bottom of the hill. The object changes shape, which changes its weight.

Answers

Explanation:

Hey, there!!

The possible reason is option no. b.

Because

for the first option its absolutely wrong. For the second option there is variation of gravity in different places so, the weight differes. (as w= m.g)For the third option, the weight changes when the object is kept at top at once and low at once but for the third time again the object is replaced at same place. so, it only gives two different weights.4th option is incorrect.

so, i think the answer is option B.

the answer has to be b

How could the notion of maximum parsimony lead to an error in establishing an evolutionary relationship

Answers

Answer:

The notion of maximum parsimony does not consider the entire evolutionary history, being able to suppress important evolutionary points that would cause errors in the evolutionary relationship of a species.

Explanation:

Maximum parsimony is a criterion for optimizing phylogenetic trees. This is because through this criterion an analysis is made of all possible phylogenetic trees of a species, observing which one is smaller and offers simpler and summary information. On the one hand, the study of the smallest phylogenetic tree can be faster and more understandable, since its information is basic and direct. However, maximum parsimony can lead to errors in the establishment of an evolutionary relationship of a species, because it suppresses the entire history of evolution of that species, being able to suppress really important points in one of the clades, which would result in an incorrect evolutionary conclusion.

Model Organism Characteristics

Yeast------------------Single celled, eukaryotic (contains a nucleus)
Fruit fly---------------Multicellular, eukaryotic, invertebrate, arthropod
Zebrafish-------------Multicellular, eukaryotic, vertebrate, fish
Mouse-----------------Multicellular, eukaryotic, vertebrate, mammal


Fruit flies, because they are multicellular like whales
Mouse, because they are mammals like whales
Yeast, because they are eukaryotic like whales
Zebrafish, because they live in the water like whales

Answers

Answer:

Because humans are multicellular, eukaryotic (contains a nucleus), vertebrates, and mammals, the best organism to test the synthetic hormones on would be a mouse.

Explanation:

Humans and whales are multicellular (they have many cells) and their cells are eukaryotic (contain a nucleus). They also have a backbone (spinal column), which makes them a vertebrate. Finally, all humans and whales are mammals. Therefore, to get the best results, the testing should be performed on a mouse.

Performing the experiment on yeast would give good results for singular-celled organisms, like protozoa.Performing the experiment on a fruit fly would give good results for multicellular invertebrates, like spiders.Performing the experiment on zebrafish would give good results for all fish in general.

The answer is a mouse

Which type of fault is under compression?
O A Transform
B. Reverse
c. Strike slip
O D. Normal​

Answers

Answer:

B. Reverse

Explanation:

The reverse fault is the type of fault that is created by two faults under compression

Reverse fault is under compression. A reverse fault occurs when the hanging wall moves upward and over the footwall due to compression forces in the earth's crust.

Reverse fault is associated with whom?

This type of fault is commonly associated with convergent plate boundaries, where two plates are moving towards each other and compressing the rock between them. The reverse fault is characterized by a steep dip angle and a short horizontal displacement.

A reverse fault is a type of dip-slip fault, where the movement of the rocks is vertical, and the hanging wall moves upward and over the footwall.

This type of fault is caused by compressional forces that push the rocks together and shorten the distance between them. As a result, the rock mass on one side of the fault plane is pushed upwards, and the rock mass on the other side is pushed downwards.

In summary, a reverse fault is a type of fault where the hanging wall moves upward and over the footwall due to compressional forces, and it is commonly found at convergent plate boundaries where the crust is undergoing compression.

A terrarium is a small, enclosed ecosystem. If you change certain aspects of the terrarium, the climate that exists inside it will also change. Examine the image of a terrarium. Then identify one attribute of the terrarium that you could change to alter the climate inside. How would this change mimic the climate changes that we see on Earth?

Answers

Answer: Putting a lid on the terrarium will increase the humidity.

Explanation:

Putting a lid on the terrarium will increase the humidity.

What is Humidity?

Humidity is a measurement of the air's water vapor content. If there is a lot of water vapor in the air, the humidity will be high. As the humidity increases, it feels more humid outside.

In weather reports, humidity is frequently described using the word "relative humidity." The percentage of the maximum quantity of water vapor that the air can hold at a given temperature that is actually present in the air is referred to as relative humidity.

A chilling -10 degrees Celsius in the air (14 degrees Fahrenheit). At this temperature, the air can only hold 2.2 grams of water per cubic meter.

You go on a trip to the Galapagos island to study the animals there for a paper you are writing on evolution, just like Darwin did. You spend 3 days taking notes on all the physical characteristics you can observe about the tortoises and then you spend 3 days observing the finches. What have you recorded? A. Inherited characteristics B. Environmental variation factors C. Phenotypes D. Genotypes

Answers

Answer:

C. Phenotypes

Explanation:

Taking notes on all the physical characteristics observed about the tortoises and then observing the finches, I have observed the phenotypes.

Phenotypes are the observable characteristics of a species which are the result of genetic expression influenced by the environmental factors.

So, phenotypes will be recorded during the trip while taking notes on all the physical characteristics which can be directly related to genotype and environmental factors.

Hence, the correct option is "C. phenotypes".

Describe how heat moves in a convection current. How is this process responsible for moving earth’s tectonic plates?

Answers

Part 1: Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Cooler liquid or gas then takes the place of the warmer areas which have risen higher. This results in a continuous circulation pattern.
Part 2: The Earth's crust is broken up into pieces called plates. The crust moves because of movements deep inside the earth. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents move the plates.

Explanation:

Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. ... Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.

How is a clade differentiated from another clade

Answers

Answer:

A clade is a grouping that includes a common ancestor and all the descendant species of that ancestor. Clades are differentiated visually based on where they branch off from one another.

Explanation:

A clade is a grouping that includes a common ancestor and all the descendants (living and extinct) of that ancestor. Using a phylogeny, it is easy to tell if a group of lineages forms a clade. Imagine clipping a single branch off the phylogeny — all of the organisms on that pruned branch make up a clade.

Clades are nested within one another — they form a nested hierarchy. A clade may include many thousands of species or just a few. Some examples of clades at different levels are marked on these phylogenies. Notice how clades are nested within larger clades

Answer:

A clade is a monophyletic grouping in which all the organisms stem from the same branching point.

Explanation:

The organisms in a clade must all stem from the same branching point in evolutionary history, as represented in the phylogenetic tree.
