I know I'm late but I too am taking the Phenomenon #2 Assessment (Part 1) and want to help any future readers : )
(I pretty much gave you guys the answer but the little facts might still help, so I didn't give the direct answer in the start)
Explanation:
Mitosis: A type of cell division that results in 2 identical daughter cells.
* Process responsible for us getting bigger
*Process that repairs damaged cells
*grows new skin for us when cut
(took this out of my teachers lesson/ CC)
While...
Cell differentiation is:
Same DNA, just different genes get expressed!
This is the reason we look different are we get older! (Not the reason we grow)
^ This above are the 2 people most likely think are the answers
Good luck : )
Extra:
Meiosis:
A type of cell division that reduces the number of chromosomes in half.
Which law regulates pesticides and herbicides? a. Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) of 1947 b. Federal Investigation of Fungicide Act (FIFA) of 1947 c. Clean Environment Act of 1949 d. Regulatory Environment Act of 1948
The law that regulates pesticides and herbicides in the USA is the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) of 1947. This law prohibits the use of certain compounds as pesticides.
The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) law is a regulatory law that provides a suitable federal regulatory framework for the use, distribution and sale of pesticides.
This law (FIFRA) is aimed at protecting pesticide users, consumers, and the environment.
The pesticides used in the USA must be licensed by the US Environmental Protection Agency (EPA).

A. It is synthesized discontinuously and uses 1 RNA primer.
B. It is synthesized discontinuously and uses multiple RNA primers.
C. It is synthesized continuously and uses multiple RNA primers.
D. It is synthesized continuously and uses 1 RNA primer.
The statement 'the leading strand is synthesized continuously and uses 1 RNA primer' is TRUE. It is replicated in the 3' – 5' direction.
The leading strand refers to the DNA template strand that is synthesized in the 3' – 5' direction during DNA replication.
The 3' – 5' direction that occurs during DNA replication is the direction of the replication fork.
RNA primers are short RNA sequences used for the initiation of the synthesis of DNA (DNA replication) both in the leading DNA strand and the lagging DNA strand.

4. Arrange Write the following steps in the order in which they occur during glycolysis
A six-carbon molecule is broken down into two three-carbon molecules.
Two NADP molecules are converted into two NADH molecules.
Two phosphate groups from two ATP molecules are joined to glucose.
Two three-carbon molecules are converted into two Folecules of pyruvate as four
molecules of ATP are produced.
The correct order of glycolysis reactions is:
Two phosphate groups from two ATP molecules are joined to glucose.Two NADP molecules are converted into two NADH molecules.A six-carbon molecule is broken down into two three-carbon molecules.Two three-carbon molecules are converted into two molecules of pyruvate as four molecules of ATP are produced.During glycolysis, the glucose molecule is converted to Glucose-6-phosphate as a result of phosphorylation. The phosphate group from ATP is joined to the glucose molecule by an enzyme known as hexokinase.
The glucose-6-phosphate then undergoes isomerization to become fructose-6-phosphate which is then phosphorylated again by the hexokinase enzyme to become fructose-1,6-biphosphate.
An aldolase enzyme converts fructose-1,6-biphosphate to one molecule of glyceraldehyde-3-phosphate and one molecule of dihydroxyacetone phosphate. The latter is then converted to another molecule of glyceraldehyde-3-phosphate.
A dehydrogenase enzyme converts glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate with NADH being generated from the reduction of NAD+.
A kinase enzyme then converts 1,3-bisphosphoglycerate to 3-phosphoglycerate with ATP being generated from ADP. A mutase enzyme quickly converts the 3-phosphoglycerate to 2-phosphoglycerate while an enolase enzyme converts the latter to phosphoenolpyruvate.
Finally, a pyruvate kinase enzyme converts phosphoenolpyruvate to pyruvate with another ATP being generated.

B.
crabs, pilchards, blennies, snappers
C.
blennies, sweeps, tiger sharks, dolphins
D.
bull kelp, sweeps, water fleas, dinoflagellates
Crabs, pilchards, blennies and snappers are the examples of secondary consumers.
Crabs, pilchards, blennies and snappers are considered as secondary consumers because they feed on primary consumer which feed on producers such as plants and algae. Secondary consumer are those organisms which feed on herbivorous organisms or primary consumers.
They can feed on producers due to different digestive system so we can conclude that crabs, pilchards, blennies and snappers are the examples of secondary consumers.

why not test for pathogens like salmonella directly rather than use an indicator organism such as a coliform?
Indicator organisms are organisms that are utilized to detect the presence of another organisms that cannot be easily identified.
We do not test for pathogens like salmonella directly but use an indicator organism like coliform because these pathogens are not easily isolated and they are much harder to identify.
Pathogens like salmonella are not tested for directly because they are much lower in numbers when found in wastes or waterbodies and to identify them directly is expensive.
Also testing directly for these micro-organisms is very expensive and non-viable. So it is better to use indicator organisms to detect their presence.
