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.

What percent of your remaining prey is mint (aa) assuming that Hardy-Weinberg equilibrium is being followed
Answer:
1%
Explanation:
If chemical signals in the cytoplasm control the progression of a cell to the M phase of the cell cycle, then fusion of a cell in G1 with a cell in early M phase would most likely result in the Group of answer choices replication of chromosomes only in the G1 cell transfer of organelles from the G1 cell to the cell in the M phase condensation of chromatin in preparation of nuclear division in both cells exiting of both cells from the cell cycle and into the G0 phase
Answer:
condensation of chromatin in preparation of nuclear division in both cells
Explanation:
Mitosis, as a type of cell division, is divided into Interphase and the Mitotic phase. The interphase further comprises of G1, S and G2 phases while the mitotic phase consists of mitosis and cytokinesis.
Mitosis is a form of nuclear division i.e. separation of genetic material (chromosome). According to this question, chemical signals in the cytoplasm control the progression of a cell to the M phase of the cell cycle.
Since what occurs in the M phase of the cell cycle is nuclear division, then fusion of a cell in G1 with a cell in early M phase would most likely result in "the CONDENSATION OF CHROMATIN in preparation of NUCLEAR DIVISION in both cells".
Conduct online research and describe how oil and gas are formed in the ocean bed and how they are tapped for human use.
Answer:
oil and gas are formed in tje ocean bed and how they are tapped for human use is below:
Explanation:
Gas and oil form in the sea over a period of millions of years, as the remains of animals and plants sink to the ocean floor. Combined with particles flushed from the land, they are buried and compressed into layers of sediment several kilometres thick on the ocean floor

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.

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.
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.
Which of the following are examples of short-term, human-induced environmental changes? Select three answer choices
Cellular Respiration releases energy by breaking down:
A. Water
B. Food molecules
C. Carbon Dioxide
D. ATP
Answer:
The answer to this question is B.
Explanation:
Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
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.
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.

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.
