Please help with this question! Last time I asked a question people were being unfair and would try to get points of me with non real answers. it has been happening a lot so please real answers! Describe how heat moves in a convection current. How is this process responsible for moving earth’s tectonic 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.
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
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".
CH3OH + HOCH3 = CH3-O-CH3 + HOH Is this reaction an addition reaction or a dehydration reaction or synthesis or whatever? A. Addition B. Dehydration Brainliest for the correct answer. Pls help
Answer:
B. Dehydration
Explanation:
Addition reaction is defined as the chemical reaction in which two different compunds combine together to form a new compund.
Dehydration reaction is defined as the chemical reaction in which water molecule (H2O) is removed from the reactant.
For example: RCO2H + R′OH ⇌ RCO2R′ + H2O
In the given equation: CH3OH + HOCH3 = CH3-O-CH3 + HOH
The reaction is showing dehydration because two molcules are combined aand water molecule is eliminated from the reactant.
Hence, the correct option is B. Dehydration.

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 type of selection is the most likely to result in Speciation?
A. Stabilizing selection
B. Directional selection
OC. Disruptive selection
D. Artificial selection
Reset Selection
Answer:
C. Disruptive selection
Explanation:
Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups. Two separate groups emerge.
Directional selection most likely to result in speciation. The correct option is B.
What is speciation?Speciation is the process by which a new plant or animal species emerges. When a group within a species separates from other members of its species, it develops its own distinct characteristics.
Speciation is the evolutionary process by which new and distinct species emerge. Species evolve through genetic modification. The new species is reproductively isolated from the previous species, which means it cannot mate with it.
Apple maggot flies - Originally only laid eggs on hawthorn apples, apple maggot flies now lay eggs on both hawthorn apples and other domestic apples in the United States.
The speciation is caused by one of the reason known as directional selection.
Thus, the correct option is B.

A____fossil is evidence of an organism, but is not made of the organism itself
A. coprolite
B. trace
C. record
D. index
Answer:
ttrace
Explanation:
A trace fossil is evidence of an organism, but is not made of the organism itself.
What is Trace fossil?The structure and behaviors of an organism, rather than its physical form, are used to classify trace fossils. A few of the trace fossils discovered in Denali have been connected to body fossils discovered in rocks from the North Slope or Talkeetna Mountains that are of a comparable age.
These connections provide investigators access to identities that are more certain than those known solely from trace fossils.
Bird tracks near probe marks in the earth suggest that the birds were using their beaks to dig for food. Invertebrate burrows located in the same rocks possibly provide the answer to what good food the birds were eating.
Therefore, A trace fossil is evidence of an organism, but is not made of the organism itself.

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.

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

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.
