Answer:
Before mitosis begins, the cell has already made new copies of each of its chromosomes. However, these new copies remain attached to the original chromosome. A dividing cell must be able to pull the copied chromosomes apart from the original copies, which is how the DNA is evenly divided when one cell splits into two.

Explanation:
cytokensis is the physical process of cell division. It divides the cytoplasm of a parental cell into two different daughter cells.
In plants, a cell wall forms. Cytokensis occurs in mitosis and meiosis. The objective for cytokensis is to divide the parent cell into two daughter cells. So cytokensis in plants is when a cell wall forms in between the daughter cells. Plant cells have walls, so they CANNOT divide using a cleavage furrow. A cell plate forms across the cell during telophase.
In animal cells, cleavage furrow forms. This pinches the cell in half and forms two different cells.

Athletes train at high altitude, thereby increasing the number of red blood cells, to improve their
performance. How might an increase in the number of red blood cells improve an athletes
performance?
Answer:
Preparing at moderate height may improve ocean level execution in perseverance competitors. This was noted after the 1968 Olympics in Mexico City (7600 feet) when a few competitors found an improvement in their presentation after re-visitation of ocean level. Be that as it may, different competitors didn't see any distinction in execution. Studies have indicated improved high-impact power in sprinters who prepared at 6,000 feet for 10 days at that point performed at low elevation. Lower oxygen levels at elevation invigorate EPO prompting expanded red platelets or hematocrit. This viably permits more oxygen to be conveyed to the tissues. Basically, this is blood doping the regular way.
Late examinations do propose profits by 'preparing low' and 'dozing high'. This incorporates hypoxic tents that numerous competitors are presently utilizing. These tents have a generator that extricates oxygen from the air, establishing a moderate height climate. Competitors at that point rest/relax in them for a few hours per day. This invigorates erythropoietin, subsequently expanding the hematocrit (red platelet tally). Without a doubt the 'live high, train low' idea may permit the best blend. One examination separated 39 contenders into three preparing gatherings; living and preparing adrift level, living at height and preparing adrift level, living at elevation and preparing at height. The two gatherings who inhabited height had expanded red platelets and VO2max, however just the gathering who lived high and prepared adrift level had improved race times. One clarification for this is that the live high, train low gathering can prepare more diligently and better use their blood's oxygen conveying limit. As a result of expanded red cell creation, all competitors preparing as well as resting at elevation should ensure they have proper iron stores and nourishment. This is particularly valid for ladies, as they will in general have lower iron stores because of occasional loss of blood through monthly cycle.

A classmate explains that igneous rocks can be changed to metamorphic rock by first being melted into magma and then cooling. What correction needs to be made to this statement?
Answer:
Cooled magma becomes igneous rock
Explanation:
Took the quiz
Rocks can be created in a variety of ways, such as when sand is crushed or when volcanoes erupt.
What are rocks?There are three different types of rocks: metamorphic, sedimentary, and igneous. These rocks can all alter. In actuality, any rock may transform into any other kind of rock.
Condensation and cooling: The Earth's interior can experience temperatures hot enough to produce magma. Igneous rock is created as crystals develop in the cooling magma.
If the lava cools gradually, as it does if it stays inside the Earth for an extended period, the crystals enlarge. The crystals will be very tiny if the magma cools quickly. Crystallization is the process by which crystals emerge from magma.
Therefore, Rocks can be created in a variety of ways, such as when sand is crushed or when volcanoes erupt.

Question 5 options:
True
False
I need help from someone who's actually helpful and smart please
Answer:
true
Explanation:
i took the test
The statement "Newton's third law of motion states that whenever a first object exerts a force on a second object. The first object experiences a force equal in magnitude but opposite in direction to the force that it exerts" is true.
What is Newton's third law?
His third law argues that there is an equal and opposite reaction to every action (force) in nature. When object A pulls on item B, object B pulls back on object A with an equal and opposing force. In other words, interactions lead to forces.
According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction pressures upon one another.
Therefore, the statement is true.

Does the cost of the technology required to create a clone exceed the benefit of producing it? is the question that can be researched to study the effect of cloning on the economy.
Reproductive cloning is a technology that can be used to produce new organisms exactly alike that of parent organisms.It has been exploited to produce high quality crops, increasing yield of food crops, increasing population of high yielding milk and meat producing animals. This technology is of economic concern. Cloning does not create new genetic information, it impacts the age of original organism, and cloned organism does have the similar personality as that of original organism but all of these are not related to economy.Hence, Does the cost of the technology required to create a clone exceed the benefit of producing it? is the question that can be researched to study the effect of cloning on the economy.

You overhear Kali describing her trip to the ocean to a friend. She explains that she waded out onto the continental rise, but was careful not to go too far, because she didn’t want to reach the steep decline of the continental slope. What part of her story needs to be corrected?
A. She needed to be careful of the continental shelf, not the slope.
B. She was on the continental shelf, not the continental rise.
C. She was on the continental slope and needed to be careful of the rise.
D. Continental slopes are not steep declines, they are gradual.
Answer:
B. She was on the continental shelf, not the continental rise.
Explanation:
The continent first contacts the ocean at the continental shelf. After a while, the continental shelf ends in a steep decline known as the continental slope. The continental slope eventually levels out into a gradually sloping continental rise which eventually becomes the ocean floor.
The part of her story that needs to be corrected is that she was on the continental shelf, not the continental rise. The correct option is B.
What is continental shelf?A continental shelf is a portion of a continent that is submerged beneath a shallow body of water known as a shelf sea.
During glacial periods, sea level drops exposed many of these shelves. The shelf surrounding an island is known as an insular shelf.
The continental shelf is where the continent first makes contact with the ocean. The continental shelf eventually ends in a steep decline recognized as the continental slope.
The continental slope eventually flattens out and becomes a gradually sloping continental rise, which eventually becomes the ocean floor.
Her story needs to be corrected because she was on the continental shelf, not the continental rise.
Thus, the correct option is B.
