You are looking under a microscope at a dividing cell. You notice
the chromatin has just condensed into chromosomes, the nuclear
membrane has started to break down and the spindle has started
forming. What phase is the cell in?
Answer:
Prophase.
Explanation:
Prophase is the phase of mitosis in which chromatin condenses into chromosomes, the nuclear membrane is started to break down and the forming of spindle has started . Prophase is the first stage of mitosis which occurs after G2 portion of interphase. After prophase, metaphase, anaphase, and telophase occurs that completes the cell division process and the one parent cell divides into two daughter cells.

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.

Sar and Dagon are the same distance from the equator, and they are
both near the ocean. Using the information in the map, how does the air
temperature of Sar compare to the air temperature of Dagon? Why The
air at Sar is?
Answer:colder
Explanation:colder than Dagon. The winds push ocean water that turns and follows the coasts. Energy is transferred from the air to the ocean at Sar and energy is transferred from the ocean to the air at Dagon.
One end of the rope is vibrated to produce a wave with a wavelength of 0.25 m. The
Frequency of the wave is 3.0 Hz. What is the speed of the wave? *
1)3.00m/s
2)2.50m/s
3)0.75m/s
4)1.25m/s
Answer:
3) 0.75m/s
Explanation:
The wavelength of a wave is calculated using the formula;
λ = v/f
Where!
λ = wavelength of wave (m)
v = velocity or speed (m/s)
f = frequency of wave (Hz)
According to this question, one end of a rope is vibrated to produce a wave with a wavelength (λ) of 0.25 m and frequency (f) of 3.0 Hz.
Using λ = v/f
v = λ × f
v = 0.25 × 3
v = 0.75m/s.

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.

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.

When you are rating evidence by its value, weigh the benefits of one good fingerprint versus hair and fiber evidence. Fully explain your answer
Answer: Conviction based on the support of the physical fingerprint is a more reliable evidence over hair and fiber evidences.
Explanation:
Physical fingerprint has more value than hair and fiber evidences. As no two fingers can have exactly alike fingerprints belonging to the same person. The fingerprints of two identical twins cannot be alike but DNA evidence obtained from hair, fiber, or any other biological evidences can show similarity. Thus physical fingerprint have more value over DNA fingerprint it can directly related to a suspect to whom it belongs to depending upon the uniqueness of the minutiae characteristics.

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.

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.
