Mitosis Inquiry Activity (10 points) 1) In the space below, sketch your group consensus pictures then write the verbal interpretation, percent of cells and name to use for each stage. Snip/Sketch,,Verbal Interpretation,Name of phase,Percent of cells
Answer:
Prophase, metaphase, anaphase, and telophase.
Explanation:
Mitosis is a type of cell division in which a single mature parent cell is divided into two daughter cells having double number of chromosomes and identical to parent cell. There are four phases of mitosis which are prophase, metaphase, anaphase, and telophase. During prophase phase, chromatin condenses into chromosomes. During prophase phase, the chromosomes of the cell align themselves in the middle of the cell. During prophase phase, During prophase phase, the splitting of chromosomes occur and the separated chromosomes goes to the opposite poles of the cell. During telophase, it results in the production of two nonidentical daughter cells.

Describe Cohesion and Surface tension, and explain how the structure of water is responsible for these properties.
Answer:
Cohesive forces are responsible for surface tension, a phenomenon that results in the tendency of a liquid’s surface to resist rupture when placed under tension or stress. Water molecules at the surface (at the water-air interface) will form
Adhesion and cohesion are water properties that affect every water molecule on Earth and also the interaction of water molecules with molecules of other substances.
Explanation:
Answer:
A water molecule, because of its shape, is a polar molecule. That is, it has one side that is positively charged and one side that is negatively charged. The molecule is made up of two hydrogen atoms and one oxygen atom. The bonds between the atoms are called covalent bonds, because the atoms share electrons.

Theoretical element “A” has four isotopes. Use the data in the table to calculate the average atomic mass of the unknown element A. All steps of the calculations must be shown for credit.
Isotope Atomic Mass Abundance
A - 49 49.022 amu 89.89%
A - 48 48.031 amu 7.01%
A - 47 48.007 amu 3.00%
A - 46 46.001 amu 0.10%
From the calculations, the average atomic mass of the element is 48.85.
What is the percentage abundance?The percentage abundance has to do with the amount of an isotope that is available in nature.
Since we have the following mass abundance;
A - 49 49.022 amu 89.89%
A - 48 48.031 amu 7.01%
A - 47 48.007 amu 3.00%
A - 46 46.001 amu 0.10%
The average atomic mass =
(0.8989 * 49.022) + (0.0701 * 48.031 ) + (0.03 * 48.007) + (0.001 * 46.001 )
= 44 + 3.4 + 1.4 + 0.05
= 48.85

How would habitat fragmentation decrease biodiversity? support with evidence.
What ideas do you have to help eliminate habitat fragmentation?
What additional policies may be needed to increase the protection of endagered species?
Answer:PREVENTION AND MITIGATION OF FRAGMENTATION
Restoration: Converting once developed land to a natural state. Mitigation: Developers create or preserve lands of similar quality and size to that which they impact. Zoning: Adding wildlife and habitat conservation considerations to lo- cal development plans.
Explanation:
Answer:
For example the amazon rainforest is the most biodiverse place on the planet. With deforestation we are putting hundreds of species to extenction and causeing the biodiversity to drop. This causes the whole planet to suffer in many ways such as less oxegen more co2. Some ways we could help eliminate this is to restrict the number of trees to be able to be cut down. This would need to be done by the brazilian government to be able to enforce it.

How are tectonic plates able to move and shift? What characteristics of Earth make this possible?
Answer:
The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth's mantle and fit snugly against one another. The heat from radioactive processes within the planet's interior causes the plates to move, sometimes toward and sometimes away from each other
Explanation:
Tectonic plates are able to move due to the convection current, and the rise in convection currents leads to the shifting of the tectonic plates, and due to the movement, there are changes such as an earthquake.
What are the consequences of plate tectonic movement?Tectonic plates are able to move and shift on the Earth's mantle, which is made up of extremely hot, thick, and dense rock that is constantly moving and the movement of the mantle is caused by convection currents, which are created by heat rising from the core of the earth, and these convection currents cause the mantle to flow, which in turn causes the tectonic plates to move, which causes earthquakes like natural disasters.
Hence, Tectonic plates are able to move due to the convection current, and the rise in convection currents leads to the shifting of the tectonic plates, and due to the movement, there are changes such as an earthquake.
