During which phases of the cell cycle are chromosomes composed of two chromatids?
Answer:
The correct phases are S phase, prophase, anaphase.
Explanation:
The cell cycle, the sequence of events spanning the period from the completion of one cell division to the end of the next division, involves both the division of the cell nucleus (karyokinesis) and the division of the cytoplasm (cytokinesis). S phase, the next section of the interface, is marked by a dramatic increase in DNA synthesis and the synthesis of histones which are major cellular proteins bound to DNA. The cell is preparing for the start of mitosis. Chromosomes duplicate lengthwise, and each chromosome consists of two identical "chromatids."During prophase, the degree of packing of the chromatin increases, so the chromosomes become shorter and thicker and the centromeres begin to become visible. Each of the chromosomes, due to its duplication in S phase, is made up of two identical chromatids, called sister chromatids. Anaphase is the short phase, the sister chromatids begin to separate and migrate to the poles. Once the two chromatids separate, each is called a chromosome.
Students use a microscope to look for structures present in four different cells. The students placed an X for each structure that was viewed for each cell on the table shown.
Which cell that was viewed is most likely a prokaryote?
Cell W
Cell X
Cell Y
Cell z
Answer:
cell x
Explanation:
This is because prokaryotes have no nucleus: their DNA is a single molecules free in the the cytoplasm. Prokaryotes have a cell wall and membrane
7: Explain how dissolving sugar in water is different than dissolving salt. What
causes this?
Answer:
For a given solvent, some solutes have greater solubility than others. For example, sugar is much more soluble in water than is salt. But even sugar has an upper limit on how much can dissolve. I hope this helps!

What is a karyotype and how do they help scientists
Answer:Karyotyping is a laboratory procedure that allows your doctor to examine your set of chromosomes. “Karyotype” also refers to the actual collection of chromosomes being examined. Examining chromosomes through karyotyping allows your doctor to determine whether there are any abnormalities or structural problems within the chromosomes.
Explanation:

What is the question?
Explanation:
pls help me I need a answer asap
Answer:
The correct order is -
a. 5 > 3 > 4 > 1 > 2 .
Explanation:
In sedimentary rocks, the bottom layer of the rock form initial and the fossils found in them would be older and the layer on top deposited the latest so the fossils found in the top layer would be the youngest.
Newer layers form or deposited on the layers of the oldest or bottom layer of the sedimentary rocks. Hence, the fossils present in the bottom layer would be the oldest fossil and newer fossils will be above them and the youngest would be top.
Thus, the correct answer is - a. 5 > 3 > 4 > 1 > 2 .

You put a marshmellow on a metal coat hanger and roast the marshmellow over an open fire. The marshmellow catches on fire. You quickly blow it
out. Before you get a chance to eat it, your hand gets really hot where you are holding the metal hanger. What type of energy transfer can explain
this situation?
Answer: Conduction
Explanation: As the fire starts to heat up the metal hanger it transfers the heat onto your hand.
Conduction Def: The process by which heat or electricity is directly transmitted through a substance
What might happen within an ecosystem if the snake population runs out of small animals to eat such as mice or rabbits?
Explain how diffusion is used to support the life processes of animals.
Answer:Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow.
Explanation:Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products. This table shows examples of substances required by cell and associated waste products.
How is water formed during the electron transport chain
Answer:
The electron transport chain is the third and final step of cellular respiration. At the end of the electron transport chain, the hydrogen from the coenzymes meets the oxygen which the cell has consumed and reacts with it to form water. Therefore, water is created as a byproduct of the metabolism reaction.

Pls help meee I will mark ❤️❤️❤️❤️
Answer: 1. Oxygen is used by cells to make energy.
2. Lungs, pharynx, larynx, trachea, bronchi, and diaphragm.
3. Blood carries oxygenated blood to the body and deoxygenated blood back to the lungs.
4. Increased amount of carbon dioxide lowers the pH of blood. Brain sends signal to the diaphragm to increase activity to get rid of carbon dioxide.
5. In the alveoli, oxygen and carbon dioxide move from high concentration to low concentration (this is also known as diffusion)
Explanation: Good luck! :D
What directions do the plates move relative to one another in a divergent plate boundary?
Identify the two main processes through which carbon is cycled between the
atmosphere and living things.
Identify the main places carbon is stored.
Answer:
Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them.
Explanation:
