Because of the fact that it was very Deep and heavily polluted.
Explanation:
Actual main channel depths along the river vary; with a least depth of 24' or less at a few locations at the channel edges to a maximum depth of 108' being found mid-channel at the southern approach to Hell Gate.
Due to heavy pollution, the East River is dangerous to people who fall in or attempt to swim in it, although as of mid-2007 the water was cleaner than it had been in decades.

What cell structure is responsible for regulating all cellular activities?
Choose 1 answer:
A. Nucleus
B. Mitochondria
C. Lysosome
D. Golgi body
Answer:
Let me know if this is right Answer: Nucleus
Explanation:
This organelle known as the Nucleus has two major functions: it stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.
Answer:
Lysosome
Explanation:
The lysosome is the cell’s recycling center. These organelles are spheres full of enzymes ready to hydrolyze, (chop up the chemical bonds of) whatever substance crosses the membrane, so the cell can reuse the raw material. These disposal enzymes only function properly in environments with a pH level of 5, two orders of magnitude more acidic than the cell’s internal pH level of 7. Lysosomal proteins only being active in an acidic environment acts as safety mechanism for the rest of the cell - if the lysosome were to somehow leak or burst, the degradative enzymes would inactivate before they chopped up proteins the cell still needed.

The Fast Plants® shown below follow the same genetic rules as the plants in the Gizmo. What is wrong with this picture?
Answer:
A
Explanation:
The genotypic mix of the two genes, or alleles, that make up an expressed trait is what causes it. Additionally, a specific gene produces a distinct protein that establishes an individual's physical traits. This is how traits are controlled by genes. Thus, option A is correct.
What is the effect of genetic rules in the Gizmo?The genotype, or set of genes an organism acquired from its parents, is ultimately responsible for the qualities that creature manifests. Each chromosome in an animal has two copies, one from each parent.
Cloning and fingerprinting are two potential applications for DNA-based identification technology.
Device Warm-Up DNA profiling compares more than just one person's full genome to another. Instead, only one specific section of the DNA is compared.
Therefore, parent 1 plant is wrong in the picture.

How is cancer related to mutations? How is it related to the cell cycle?
Answer:
Cancer is related to the cell cycle bc, cancer cells mutate. Cancer is unchecked cell growth. Mutations in genes can cause cancer by making cell division rates go up faster or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death.

Explain why a swing will not stay in motion forever after you have given it a push. What happens to the mechanical energy of the swing?
Explanation:
As the pendulum swings back and forth, the balance between the two types of energy changes constantly. At some points in its swing, the pendulum has more kinetic energy. At other points, it has more potential energy. ... No pendulum can swing forever because the system loses energy on account of friction.
