Why is plastic a non-biodegradable and nonpoint source of pollution?
Plastic is a non-biodegradable and non-point source of pollution because it cannot be broken down into degradable materials by micro-organisms. It comes from man-made substances and industries therefore, it is non-point pollutant.
What is Plastic?Plastic is a non-biodegradable and non-point pollutant. Because, the enzymes in the microorganisms cannot break down the waste into bio-degradable materials as microbes cannot recognize the bonds that hold these polymers together. Eventually, the polymers in plastic may break down, perhaps after hundreds of years. But after a long time, the damage is already done to the environment.
Nonpoint source of pollution comes from oil, pet waste, herbicide, bacteria, sediment, and any other contaminant that ends up on the ground naturally or from human activity.

A doctor sees a patient who has kidney failure, lack of motor coordination, and a poorly functioning nervous system. After testing, the doctor finds that these symptoms are all related to a chronic lack of energy in some of the patient's cells. The doctor diagnoses a metabolic disorder known as Leigh's disease.
Based on this evidence, a malfunction in what organelle is most likely responsible for Leigh's disease?
Mitochondria are the energy centers of the eukaryotic cells. In these organelles, ATP (the energy coin of the cell) is produced by the oxidation of pyruvate (Krebs cycle) and oxidative phosphorylation.
Based on this information, malfunction in MITOCHONDRIA is most likely responsible for Leigh's disease.Cellular respiration is series of metabolic reactions by which eukaryotic cells produce energy in the form of ATP from foods and oxygen.Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.Glycolysis occurs in the cytoplasm, whereas the Krebs cycle and oxidative phosphorylation occur in the mitochondria.Learn more in:

Active transport of fluid and electrolytes across the cellular membrane typically requires?
Active transport requires energy in the form of ATP conversion, carrier proteins, or pumps in order to move ions against the concentration gradient.
Active transport of fluids and electrolytes across the cell membrane normally requires the expenditure of energy (eg, in the form of ATP) to move a substance against its concentration gradient.
Active or passive transport?Passive transport is a great strategy for moving molecules into or out of the cell. It's cheap, easy, and all the cells have to do is stop and let the molecules diffuse.
In active transport, as opposed to passive transport, the cell expends energy (eg, in the form of ATP) to move a substance against its concentration gradient.
With this information, we can conclude that the active transport of fluids and electrolytes across the cell membrane normally requires the expenditure of energy (eg, in the form of ATP) to move a substance against its concentration gradient.

Answer:
The cell theory states that all living beings are made of cells. There is a debate as to whether or not viruses should be considered to be alive. The debate results from the fact that viruses cannot reproduce on their own. They must invade a host cell and utilize the host’s genetic material in order to reproduce. Viruses are not true cells. They lack the most important part of the cell, the protoplasm. Hence, the cell theory is not applicable to viruses. Hence, the answer is C.

. How much time does it take a person to walk 12 km north at a velocity of 6.5 km/h
Answer:
It will take 1.85 hours to walk 12 km north.
Answer:
Explanation:
v=[tex]\frac{d}{t}[/tex]
and the d here is the distance which is equal 12 km
the time is still unknown
and we know the velocity which is 6.5 km/h
and according to the triangle of the velocity "search that up "
t =[tex]\frac{d}{v}[/tex]= [tex]\frac{12}{6.5}[/tex]≈1.8 hours

An organism that breaks down hydrogen sulfide as a source of energy and gets its
carbon from carbon dioxide would be classified as a:
a. Chemoautotroph
b. Photoheteroptroph
c. Chemoheterotroph
d. Photoautotroph
Photoheterotrophs. A heterotroph is an organism that depends on organic matter already produced by other organisms for its nourishment. Photoheterotrophs obtain their energy from sunlight and carbon from organic material and not carbon dioxide.

Which would conserve more energy if all humans ate only vegetables or ate only meat
Answer:
There would be more conservation of energy if human beings it only meat.
Explanation:
this is because meat consists of a significant portion of the fat. The amount of of energy that is liberated per molecule of fat is almost twice the amount of energy that is liberated by carbohydrate or protein. As a result of this the total energy consumption will be more if human being consumes only fat. however it takes more time to digest fat as compared to that of carbohydrate and protein.

Explanation:
Compare geologic time with the geologic column . (Earth science )
Answer:
The geologic time scale (GTS) is a system of chronological dating that classifies geological strata (stratigraphy) in time. It is used by geologists, paleontologists, and other Earth scientists to describe the timing and relationships of events in geologic history. The time scale was developed through the study and observation of layers of rock and relationships as well as the times when different organisms appeared, evolved and became extinct through the study of fossilized remains and imprints. The table of geologic time spans, presented here, agrees with the nomenclature, dates and standard color codes set forth by the International Commission on Stratigraphy (ICS).
