John Pierpont Morgan<span> Sr. (April 17, 1837 – March 31, 1913) was an American financier and banker who dominated corporate finance and industrial consolidation in late 19th and early 20th Century United States.</span>
Answer:
Part A: The process of sexual reproduction is important because by this process organisms with varied genetic characteristics can be formed. Crossing over and independent assortment allow individuals to be born which are not alike to another and their parents. As a result, genetic diversity is produced.
Part B:
The process 1 is meiosis. The process 3 is development by mitosis.
The reproductive organs form sperm and egg by the process of meiosis. During this process, the number of chromosomes is reduced so that the number of chromosomes of an individual can be maintained.
The zygote converts into an embryo in a process called germinal development. The zygote replicates by mitosis to form into an embryo.
<span>It is through whistles that dolphins interact with the pod. Each dolphin has a distinct whistle that identifies it with other dolphins of its pod. If an individual is in danger, it uses a particular noise that indicates aid is needed, so the pod responds quickly.

Small dolphin species gather into multi-member pods as a way to compensate for their size when facing predators.</span>
Answer:
Tight junctions are specialized regions of the plasma membrane that mediate separation of the apical and basolateral membranes.
Explanation:
Transcellular Transport is the pathway in intestinal epithelial cells where particles move from one cell to another depending on the physicochemical properties of the particles passing both the the apical membrane and basolateral membrane. Tight junctions create a paracellular barrier in epithelial and endothelial cells protecting them from the external environment
<h2>Answer:</h2>
Reaction for observation: Sodium Hydroxide + Copper Sulfate
Full reaction:
2NaOH + CuSO4 --> Cu(OH)2 + Na2SO4
<h3>Part 1.</h3>
Observations Before Interaction:
Sodium hydroxide is a turbid solution and copper sulfate is in form of bright blue crystals.
<h3>Part 2:</h3>
Observations After Interaction:
When their solutions are mixed with each other, a pale blue precipitate of basic copper hydroxide & a solution of neutral salt sodium sulphate will be formed.
<h3>Part 3:</h3>
Was Mass Conserved?
Yes, mass was conserved.
The Law of Conservation of Mass states that "mass cannot be created or destroyed, but changed into different forms".
Hence mass was conserved.
<h3>Part 4.</h3><h3>.Proof of a Chemical Reaction</h3>
The proof of the reaction is the appearance of pale blue precipitates of of basic copper hydroxide & a solution of neutral salt sodium sulphate.
