How can you decrease the effort force needed to push a weight to the top of the ramp? A) cover the surface with carpet B) increase the length of the ramp C) increase the height of the ramp D) decrease the length of the ramp
Answer:
B) increase the length of the ramp
Explanation:
Less force is needed to move the object over a longer distance.
Answer:
You can decrease the effort force needed to push a weight up the ramp if you increase the length of the ramp. You could also decrease the height of the ramp.Lengthen the ramp, decrease the mass of the object, use a machine can you decrease the effort force needed to push a weight
Explanation:
A ramp is an example of an inclined plane. Think back to the example of the ramp and the moving truck. The ramp reduced the amount of force needed to lift the box by moving it over a greater distance. The longer an inclined plane, the less force is required to move an object upward.

Check
Answer:
c
a
b
Explanation:
Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.
In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.
Can readily transport nutrients from rock to aquatic ecosystems. Runoff that carries excess nutrients can cause algae blooms.The effects of soil erosion. Thus, option B is correct.
What is soil erosion?The removal of the top of the soil by water, wind and human activities has been called soil erosion. The reason due to which soil erosion takes [place is that trees should be planted in several rows to check the speed of the wind. This reduces soil erosion because of wind. Because the rivers cause soil pollution, dams are built in the upper course of the rivers to check soil erosion.
Soil erosion has happens when the dirt has been exposed to the high winds, heavy rains, and rushing water. In few circumstances, human activities, like farming and land clearance, expose soil to erosion. Soil erosion has been considered as the removal and transfer of the top layer of soil from its original location to another due to high winds and fast-running precipitation.
Therefore, Both rock and bodies of water are considered a type of reservoirs. Thus, option C is correct.
In cycles of matter when rock has been exposed for mining, the answer is water. Thus, option A is correct.
Can readily transport nutrients from rock to aquatic ecosystems. Runoff that carries excess nutrients can cause algae blooms.The effects of soil erosion. Thus, option B is correct.

A researcher attempts to use a segment of ribosomal RNA as a molecular clock to calculate the date of the last common ancestor of two species. He finds that the two species diverged from a common ancestor 150 million years ago. These particular species have abundant fossil records that strongly suggest that these species diverged 100 million years ago. Which of the following answer choices best describes a reason for the discrepancy in the date of the last common ancestor of these species?
A. Ribosomal RNA is not a reliable molecular clock and should not be used for dating.
B. The neutral mutation rate used in calculating the last common ancestor date may not have been accurate.
C. It is highly likely that the two organisms did not share a common ancestor, so the results are invalid.
D. A large portion of the ribosomal RNA is not vital to survival, so it is not likely to be well preserved.
Answer:
B
Explanation:
It is B because the mutation rate should not have been accurate if it showes that they diverged 150 million years ago. But the abundant fossil records show that it diverged 100 million years ago.
Hope this helps:)
Ribosomal RNA is not a reliable molecular clock and should not be used for dating.
What is molecular docking?In structural molecular biology and computer-assisted drug design, molecular docking is an important technique. The purpose of ligand-protein docking is to anticipate a ligand's most common binding mode with a protein having a known three-dimensional structure.What is dating? Carbon dating is used to determine the age of ancient material such as an archaeological or paleontological specimen .A molecular clock estimates how long it has been since similar species separated from a common ancestor based on DNA sequences (or the amino acid sequence of proteins encoded by DNA).
Hence, the correct option is A.

Natural selection is affected by which three factors? A. reproduction B. evolution C. variation D. overproduction E. mechanism F. competition
Natural selection is affected by evolution as three factor. The correct options are A, B and C.
Thus, Natural selection results in the transmission of advantageous genetic variants through reproduction.
As a result, a new generation of organisms emerges that has a higher chance of surviving and reproducing.
For instance, giraffes have an edge over other species due to their long necks, which have allowed them to graze on leaves that others cannot reach.
Because they had access to greater food, those with longer necks were able to breed and pass on the trait to the next generation. Less likely to survive and pass on their genes would be those with shorter necks and access to less food.
Thus, Natural selection is affected by evolution as three factor.The correct options are A, B and C.

Given the following phylogenetic tree, which evolutionary event occurred most recently?
A.) development of different forms of symmetry.
B.) development of tissues.
C.) each of these traits evolved at the same time.
D.) protostome and deuterostome development.
Answer:
Option-D
Explanation:
A phylogenetic tree is a diagrammatic representation which is constructed in to show the common ancestors at the base of the tree and the branches represent the new species.
The phylogenetic tree which is constructed based on the traits evolved during evolution is known as a cladogram. In the given question, the cladogram represents the evolution of various groups of the organism from a common ancestor based on the traits evolved.
The trait which was evolved earlier is present at the base like the development of tissues while the most common trait is present at the top which is the development of deuterostome and protostome.
Thus, Option-D is the correct answer.
