Please help I will give BRAINLIEST face the earth
Answer:
It is often assumed that the moon is a perfect sphere, which it is not. The side of the moon facing earth is more dense than the side facing away. Therefore, it takes energy for the moon to rotate its earth-facing side away from the earth. Such energy is not currently available, so the same side always faces earth, caught in earth’s gravity.
Explanation:
Hope this helps you a lot my boo!
Answer:
The moon keeps the same face pointing towards the Earth because its rate of spin is tidally locked so that it is synchronized with its rate of revolution (the time needed to complete one orbit). In other words, the moon rotates exactly once every time it circles the Earth

The distance versus time graph for Object A and Object B are shown.
A graph titles Distance vs Time. A straight slanting line is drawn through point 7 on y axis and this line is labeled Object A. The graph for Object B is a straight slanting line passing through the origin
What is the similarity between Object A and Object B?
Both have the same slope.
Both move with variable speed.
Both move with constant speed.
Both start the journey from the same point.
Answer:
The correct answer is - Both move with constant speed.
Explanation:
If an object moves in a particular way that it covers the same distance at the same times the speed considered as constant suppose if two objects a and b both travel 10 m and 20 m respectively and the time they take in travel are 2 and 4 seconds respectively than we can say they both have a constant speed.
The relation between the variables x,t, and v is
x=v.t
If V is constant which is the speed we get a straight line x-t in the graph.
By the given information we can say that both objects A and B are traveling at a constant speed.

A teacher modeled part of a DNA molecule using two of these coiled springs. Which part of the DNA was the teacher most likely modeling?
Answer: The part of DNA that the teacher was modelling would be the backbone of DNA.
Explanation:
The DNA is made of double helical structure which is twisted. In the structure of DNA two strands are coiled among each other.
The DNA consists of the nitrogenous bases, phosphate groups and deoxy-ribose sugar.
The backbone of DNA is made up of sugar( alternating )and phosphate group.The nitrogenous bases such as adenine, cytosine ,guanine and thymine are joined to the deoxy-ribose sugar.
This backbone part was part that the teacher was making as a model by using two coiled springs.
Describe the basic process of DNA replication and how it relates to the transmission.
Answer: At the replication fork, the helix unwinds into 2 separate strands.
Explanation: DNA polymerase joins individual nucleotides to produce a new strand of DNA. This makes a brand new strand that is identical to the first. The DNA first replicates its information to ensure it is the same in the new strand.

The purpose of the Darwin Finch lab was to establish that the relationship between food sources and beak shape was a taste preference.
a. True
b. False
Answer:
False. The purpose of the Darwin Finch lab was to establish that the relationship between food sources and beak shape was food availability.
Explanation:
Finches speciation was due to geographical isolation on islands and the differences in their picks were an evolutive adaptation that reflected feeding habits. Their speciation depended on or was the result of their adaptation to the island and its characteristics. The finches´ beaks evolved according to food availability. Large beaks are better for islands with larger seeds, while pointed beaks are better for getting insects out of trees.
Are fibrous proteins heavier than globular proteins in terms of molecular weight? Why?

Explanation:
Which best describes why projectiles move in a curved path?
How can natural selection result
in the adaptation of a population?
Answer: The traits of those who died before reproducing deemed "undisireable" (like a tale,scales,wings etc.) would have died out as they would not have had the opportunity to pass on these genes. Those of the same species who survived due to a lack of the "undisireable" trait would have the opportunity to reproduce and pass on the complete lack of the trait itself or a smaller version of the trait. This is what enables different species to adapt to live in different enviorments,you can observe this in different species that share a common ancestor.
Explanation: It's kind of in the answer
revisions to predictions about scientific phenomena can be based on
The correct answer is D. All of these
Explanation:
Scientific predictions are based on previously recorded information, which includes observations, data gathered with precise instruments, mathematical models, measurements, among others. This allows scientists to understand phenomena objectively by using the scientific method and to make accurate predictions.
Despite this, scientific predictions might slightly, or completely change over time. This is because new tools or methods might provide scientists with new contradictory evidence about the phenomenon. Moreover, any type of evidence gathered as part of the scientific method is valid to evaluate a previous prediction such as observations, data, models, measurements, among others.

How does the process of hydration cause chemical weathering?
A.
Water reacts with iron minerals in rock to form rust.
B.
Moving water transports sediment from rock.
C.
Increased density adds pressure to the molecules in rock.
D.
Acidic water dissolves calcite in carbonate rocks.
Answer:
A. Water reacts with iron minerals in rock to form rust.
Explanation:
Generally, weathering is the process by which rocks are broken down or disintegrated into smaller particles. However, as the name implies, chemical weathering is the weathering facilitated by chemical reactions.
However, there are various types of chemical weathering, of which one is HYDRATION. Hydration is a type of chemical weathering which involves the reaction of water with the chemical constituents of rocks, which eventually disrupt or changes the structure. Therefore, in chemical weathering, water reacts with iron minerals in rock to form rust.
Sandra was trying to water the flowers with the hose, but even with the water turned up to full force she could not get it to reach the farthest flowers. Her sister told her to cover part of the end of the hose mouth with her thumb. When she did this, the water shot out farther. Why did putting her thumb over the end of the hose make a difference?
A. The thinner stream of water could travel farther because it was lighter.
B. Sandra added more energy to the water by making it swirl inside the hose.
C. The same amount of energy in the water was forced through a smaller space.

Are fibrous proteins heavier than globular proteins in terms of molecular weight? Why?
Answer:
Proteins range in molecular weight from 1000 to more than 1 million daltons (Da), but the folded size of a globular protein is not necessary correlated to its molecular weight. Proteins composed of about 250 amino acids or less often have a simple, compact globular shape. Larger globular proteins are usually made up of two or more recognizable and distinct structures, termed domains or modules. These are compact, folded protein structures that are usually stable by themselves in aqueous solution. Typical domain structures consist of hydrophobic cores with hydrophilic surfaces. Individual domains often possess unique functional behaviors and often perform unique functions within the larger protein in which they are found.
Does Evolution Exist?
Answer:
yes evolution do exist in nowadays also.
How can traits affect fitness and how
can natural selection change the
presence of certain alleles over time?
Answer: Natural selection allows the survival of organisms with beneficial traits.
Explanation:
Natural selection can be defined as the differential survival and reproduction of the members of the population that have beneficial phenotypic traits to survive in unfavorable environment. These organisms reproduce and pass on their traits to the next generation such species does not extinct in future.
The natural selection allows evolution of species with the adaptation of new traits so as to allow the survival of the organism.

When a cell needs energy, it brings in nutrients and break it down and supply energy to the cell
Answer:
This question is incomplete, the complete question is: When a cell needs energy, I take in nutrients break them down, and supply energy to the cell. I can also convert stored energy in the cell to food. I am a?
The answer is MITOCHONDRION
Explanation:
All living organisms need energy at the cellular level to carry out their cellular activities. This energy is obtained by eating food. The energy in food is stored in the bonds of the sugar molecule that is contained in it.
However, via a process called CELLULAR RESPIRATION, the stored energy in food is broken down and used to synthesize a form of energy usable by the cell called ATP. This important process occurs in the organelle called MITOCHONDRION.
