A classmate states that animals that result from artificial selections are lucky since they have better traits than bred animals. giving your study of this topic, do you agree? Explain.
Answer:
the classmate is correct
Explanation:
they are luckier than most. for example
take a brown beetle in a green forest
and there will be some few green beetles, which is the artificial selection
those green beetles will survive better than the brown ones and this they have better traits. and the green beeetles will make up most of the population of beetle after a while. this is becuase the brown beetles need to evolve over time to the environment which will take a long time.

Modern organisms have some similarities to organisms that are now extinct. What is one possible explanation for this?
Answer:
Darwin's theory its simple thus that do not evolve shall dissolve meaning if an organism cannot keep up with the environment around it it will die off and if it can it will evolve.
Explanation:being that there are many species of cat that prolly come from one organism they all evolved according to there needs
The idea of evolution is one explanation for the similarities between living things and extinct ones, such as the Smilodon saber-toothed tiger and contemporary cats. Through the processes of natural selection, genetic drift, and gene flow, populations of species undergo evolution over time.
What is an Evolution?Natural selection, genetic drift, and gene flow are three processes that allow populations of organisms to change over time. This process is known as evolution.
When populations of organisms diversify and some individuals have traits that are more beneficial to their environment than others, evolution occurs. This causes the evolution of new species over time that are more adapted to their surroundings.
For example, the evolution of modern cats from the Smilodon saber-toothed tiger probably occurred over a long period of time through a succession of small changes in the cat population. Eventually, the evolution of the contemporary cat was influenced by cats that had somewhat sharper teeth or a greater hunting ability because they were more successful at catching prey and passing on their genes.
Therefore, the idea of evolution is one explanation for the similarities between living things and extinct ones, such as the Smilodon saber-toothed tiger and contemporary cats.

At which location does the marble have maximum kinetic energy?
Location W
Location X
Location Y
Location Z
Answer:
location Y
Explanation:
The KE of a pendulum bob is maximum where it moves fastest, at the lowest point; PE is maximum at the uppermost points. When the pendulum bob swings by the point that marks half its maximum height, it has half its maximum KE, and its PE is halfway between its minimum and maximum values.
Can you Mark a brainlest Please
The kinetic energy of a pendulum bob is maximum when it moves fastest, at the lowest point. Potential energy is maximum at the uppermost points. When the pendulum bob swings by the point that makes half it's maximum height, it was half it's maximum kinetic energy and it's potential energy is halfway between it's minimum and maximum values. Thus, option c is correct.
What is kinetic energy?Kinetic energy is a form of energy it possess when any object or person is in motion . It can be defined as the work needed to be done to produce a motion in a object from rest position.
If we want to acceleration in an object then we must apply a force on a object to give motion so we can say that we required to do work for acceleration and then we can say that required is equal to kinetic energy.
Mathematically,
Kinetic energy =1/2mv^2
Where
m = mass of object.
v = velocity of object
Kinetic energy is vector quantity it means that it have both i.e magnitude and vector.
S.I unit of Kinetic energy is Joule.
Therefore, Potential energy is maximum at the uppermost points. When the pendulum bob swings by the point that makes half it's maximum height, it was half it's maximum kinetic energy and it's potential energy is halfway between it's minimum and maximum values. Thus, option c is correct.

A classmate states that animals that result from artificial selections are lucky since they have better traits than bred animals. giving your study of this topic, do you agree? Explain.
Answer:
See answer below. Hope it helps.
Explanation:
This can have advantages and disadvantages. The artificially selected animals could have better traits than naturally selected animals, but in the long run, it will be harder for them to evolve and adapt to new environments because of the lack of variation in their traits.
Artificial selection has long been used in agriculture to produce animals and crops with desirable traits. The meats sold today are the result of the selective breeding of chickens, cattle, sheep, and pigs. Many fruits and vegetables have been improved or even created through artificial selection.
What is an example of natural selection What is an example of artificial selection?Natural selection includes the selection of long-necked giraffes and the changes in the size and shape of the beaks of birds according to their feeding habits. Some examples of artificial selection include dog breeding to produce new breeds of dogs and cross-breeding in cash crops like wheat and rice.
How is the artificial selection done?Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

During which process do cells change chemical energy into something usable?
photosynthesis
DNA
ATP
respiration
Cellular respiration is the process of transforming chemical energy into forms usable by the cell or organism.
In respiration, cells change chemical energy into something usable. So, the correct option is D.
What is Cellular respiration?Cellular respiration is defined as the process by which organic fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy to drive the bulk production of ATP.
Cellular respiration is explained as the process of transforming chemical energy into forms usable by the cell or organism. Respiration is called a catabolic process, which breaks down large molecules into smaller ones, releasing energy to fuel cellular activities.
It is represented as:
Glucose + Oxygen → Water + Carbon dioxide+ Energy in the form of ATP
Thus, in respiration, cells change chemical energy into something usable. So, the correct option is D.

Compare and contrast the Andes Mountains and the Rocky Mountains. How are they formed? What consumers and producers are in each?
Answer:
quora does help ;)
Explanation:
Both were formed from overthrusting. Overthrust mountains are formed when one tectonic plate crumples over on top of the old rock that lay in its path. The Rockies were formed when the N. American plate moved westward and the plate in its path was shoved on top of N. America.
The Andes are also overthrust mountains, but unlike the Rockies there are extinct, dormant and active volcanoes in the Andes. The tallest of these is Ojos del Salado, which peaks at over 22k feet asl. It lies in the southern volcanic belt of the Andes on the border of Chile and Argentina. There are 3 other volcanic belts in the Andes.
The Andes appear to be newer than the Rockies. They are more seismically active, they have active volcanoes in them and they are much higher, indicating that not enough time has elapsed to erode them very much.

1) How does air pressure affect breathing?
2) How do alveoli help gas exchange in the lungs?
3) Explain the job of the diaphragm muscle.
4) What two body functions do lungs support?
Answer:
1) The air pressure in your lungs has to be less than the air outside your lungs, to get your lungs to inflate.
2) Alveolar sacs are surrounded by thin capillaries where gas can be it's changed
3) The diaphragm, located below the lungs, is the major muscle of respiration. ... Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs
4) I don't quite understand what you mean by that but I'll give it my best shot. The lungs' main role is to bring in air from the atmosphere and pass oxygen into the bloodstream. From there, it circulates to the rest of the body. The organs require help from surrounding structures in the body in order to breathe properly. The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood. A reduced lung function means that the ability of lungs to exchange gases is reduced Adaptations of the alveoli: Moist walls - gases dissolve in the moisture helping them to pass across the gas exchange surface. Permeable walls - allow gases to pass through. Extensive blood supply - ensuring oxygen rich blood is taken away from the lungs and carbon dioxide rich blood is taken to the lungs.
