Answer:
Phytoplankton.
Explanation:
Phytoplankton, which is Greek for "drifting plants" are microscopic, one-celled organisms that drift in the sunlit areas in the oceans and they are key to bringing carbon down into the ocean biological pump from the atmosphere via the process of photosynthesis.
Phytoplankton are super important! They generate about 50% of the atmosphere's oxygen, which is the same amount as all land plants combined. They also form the base of virtually every ocean food web. In short, phytoplankton makes other ocean (and land) life possible.

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?
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.
Therefore, Putting a lid on the terrarium will increase the humidity.

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
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.Learn more about aerobic respiration:

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

As Earth’s climate changes over time, so will its energy budget. One possible effect of a changing climate is changes to cloud cover. If the amount of cloud cover on Earth were to decline, what effect could that have on the amount of energy absorbed by land and oceans?
Answer:
The amount of energy obsorbed by the ocean and land would increase.
Explanation:
Clouds reflect energy from the sun back into space. If there is more cloud cover than there is less energy reflected therefore more is obsorbed.

Runoff:
As the water falls due to precipitation termed as rainfall which usually streams down the earth to various water bodies such as lakes, rivers and oceans. This is known as runoff.
Infiltration:
the movement or going back under the surface of the earth or ground is known as infiltration and it is necessary to maintain ground level of water.
Transpiration:
The roots of the plants absorbs the water that went through the soil which move to various part of the plant body from their it evaporates and move to the atmosphere. It is known as transpiration.

How is a clade differentiated from another clade
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.

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.
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.
stion 6/48which would be the best evidence that a cell is using active transport to move a substance across its cell
membrane?
A) Substances are moving rapidly across the cell membrane.
B) ATP is being rapidly consumed near the cellular membrane.
C) Substances are moving from high to low concentrations.
D) Substances are moving through channels in the cell membrane.
Answer:
B) ATP is being rapidly consumed near the cellular membrane.
Explanation:
Active transport is a form of transport used by living systems in which substances/molecules move across a membrane from a region where they are less concentrated to a region where they are highly concentrated. This movement occurs against the concentration gradient, hence it requires energy in form of ATP in order to occur. The transport is said to be "ACTIVE" if it is energy consuming.
Hence, based on the explanation above, the best evidence to showcase the occurrence of active transport in a cell is the rapid consumption of ATP near the cellular membrane. ATP will be used to pump needed substances into the cell via the cell membrane, serving as the semi-permeable membrane.
