Cuando pasa una molécula de una zona de menor concentración de sustancias a una zona de mayor concentración, el transporte implicado es
Answer:
Transporte activo.
Explicación:
El transporte activo ocurre cuando una molécula se mueve de un área de menor concentración de sustancias a un área de mayor concentración. Los transportes activos utilizaron energía en forma de ATP para mover moléculas en contra del gradiente de concentración. Es lo opuesto al transporte pasivo en el que no se requiere energía para mover moléculas de una región a otra. La principal razón de que ocurra el transporte activo es que mueve moléculas en contra del flujo de difusión. En difusión, la molécula se mueve de un área de mayor concentración a un área de menor concentración.

Do you think that genetics is the only force behind appearance and behavior? If not, what else impacts human development? How large a part does genetics play in who you are?
Answer:
Genetics play a part in who you are by creating the way you look, or what your appearence looks. Behavior can be a different thing, some types of common behaviors or sicknesses do show up, but the way you act most of the time is your choice, not your genetics. Sometimes your genes can limit you to some things but if there is a certain way you want to behave, thats on you.

Which type of tectonic plate interaction forms a mid ocean ridge?
Answer:
Divergent plate
Explanation:
A semi ocean ridge is formed by the interaction of divergent boundaries. Around divergent plate boundaries, as additional sea floor is formed as the Earth's tectonic plates expand outward, half ridges form. Igneous material grows to the ocean bottom when the plates split, resulting in massive basalt volcanic activity.

Watch the seven minute video on the "Mystery of the Buffalo boom" on you tube. Write a reflection on how scientists used their reasoning skills to make a claim about causes of the "buffalo boom".
Answer:
In the "Mystery of the Buffalo boom" scientists first try to find the answer in the two most common things that can affect a population of animals. Food and predators.
First, they studied the buffalos' food supply, grass. They found that there has not been an increase in it so that the number of buffalos multiplied.
Then they studied the predator's population, and they found that there was not a decrease in the number of them that could affect the buffalos increasing numbers.
As the two main things that controlled a population were not affected, they had to find other causes. The next thing that they studied were historical facts about buffalos and diseases. Scientists discovered that a virus that affected cows had impacted these animals too, which was the cause of a considerable decrease in the buffalo's population many years back.
Due to the drastic impact that the rinderpest had on cows, a vaccination plan was implemented. As the cows now were protected against this virus, the virus could not reproduce as it did, ending the spreading of this disease in cows. As a consequence, the buffalos were no longer infected, and their population grew thanks to the vaccination plan.
In conclusion, when the most common things that can affect a population are not the cause, we have to look into the past and find what has changed and how it impacted the animals. It is using logical thinking skills to determine what has changed and what that change made.
Explanation:
In the video "Mystery of the Buffalo boom" the ecologist Tony Sinclair found an abnormal buffalos' number in Tanzania. As the increase in the buffalos' population was something unusual, he knew that something had changed, but he did not know what. Sinclair, with other scientists, used their reasoning skills and thought that the two most logical things that can affect a population are food and predators. When they studied these two variables, they found out that they were not the problem. The next step was to look for past events that impacted buffalos. They found out that a virus, which directly affected cows but also buffalos, had been erased from the Earth thanks to a vaccination plan. As a result, the disease spreading between cows stopped, and as a consequence, it also stopped between buffalos.
We can see that everything is connected and that by using reasoning skills and logic, scientists could determine what happened.

Show how artificial selection could be used to develop a new breed of wheat with higher fiber content
Answer:
get wheat that has the desired content (in this case high fiber content)
breed them
amongst the offsprings/ wheat produced, select the ones with highest fiber content
breed them
repeat this process for many generations
Explanation:
Artificial selection is a process of selective breeding where humans choose certain traits to breed for in plants or animals.
What would happen in case of wheat?In the case of wheat, we could use artificial selection to develop a new breed of wheat with higher fiber content by selecting individual plants with the desired traits and breeding them together over several generations.
Below are the steps:
Identify wheat plants with higher fiber content: The first step would be to identify individual wheat plants that have naturally higher fiber content. This could be done by analyzing the fiber content of different varieties of wheat and selecting those with the highest fiber content.
Crossbreed the selected plants: Once we have identified wheat plants with high fiber content, we can crossbreed them to create a new hybrid variety. This involves taking the pollen from one plant and fertilizing the flowers of another plant with it. The resulting seeds will have a mix of genetic traits from both parent plants.
Select the desired traits in the hybrid plants: After the hybrid plants have grown, we would need to evaluate them for their fiber content. We would select the plants with the highest fiber content and use them as parents for the next generation of plants.
Repeat this process for several generations: The process of selective breeding would be repeated over several generations, with each generation being evaluated for fiber content and only the plants with the highest fiber content being used for breeding. This would increase the likelihood of producing a new wheat variety with consistently high fiber content.
Test and refine the new wheat variety: Once a new wheat variety with higher fiber content has been produced, it would need to be tested for its nutritional value, taste, and other characteristics. If the new variety meets the desired criteria, it could be released for commercial production.
In summary, artificial selection can be used to develop a new breed of wheat with higher fiber content by selectively breeding individual plants with high fiber content and repeating the process over several generations until a new variety with consistently high fiber content is produced.

Sand for beaches comes from rocks in the area that are weathered down, and
their sediment is deposited in the area beaches. The beaches are then eroded,
and the sediment is moved away from the beaches. If rocks stopped weathering,
how would the beach change?
Answer:
Beaches would shrink until they were no longer there because the sediment is pulled away from the shores by the tide and there would be no new rock sediment to replace the old rock sediment.
If two species have similar DNA sequences, it would indicate that they
A. Have no evolutionary relationship
B. Share a common ancestor
C. Are not closely related
D. Will have similar fitness
Explanation:
90% sure its gonna be B lol
If the DNA sequences of two species are identical, this would indicate that they share a common ancestor. So, the correct option is B.
What is Ancestry?An ancestor is also called forefather, fore-elder, or a forebear. It is defined as the parent of the parent or predecessor. An ancestor is any person from whom one is descended living in law, a person from whom property is inherited.
Ancestry links genetics and society in fundamental ways, while it has cultural, religious or political significance, and can play an important role in shaping personal and public identity.
Homologous can occur when different species have similar anatomy that is shared due to ancestry or shared due to similar selective pressures.
Thus, if the DNA sequences of two species are identical, this would indicate that they share a common ancestor. So, the correct option is B.
