Answer:
Because cholera bacteria rapidly multiplies in areas with improper sanitation and untreated water that people can drink.
When people drink this water, they get severe diarrhoea.
When methane (CH4) combines with oxygen (O2), carbon
dioxide (CO2) and water vapor (H20) are produced.
Which equation represents this chemical reaction?
O A. CO2 + CH4 + 2H20 + 202
OB. CO2 + 2H20 – 202 + CH4
OC. CH4 + 202 – CO2 + 2H20
OD. CH4 + 2H20 - 202 + CO2
Answer:
C. CH4 + 202 – CO2 + 2H20
Explanation:
CH4+O2-CO2+H20
The above equation represents combustion of methane to produce carbon-dioxide and water.
One carbon atom is present on the reactant side as well as on the product side. Four hydrogen atoms are present on the reactant side and two hydrogen atoms on product side. In order to balance this equation, we would multiply water molecule by two. Now there are four atoms of oxygen in the product side but only two on reactant side, so we will multiply oxygen molecule by two on the reactant side. Now the equation is balanced.
The balanced chemical equation is:
CH4+202-CO2+2H2O
This equation obeys the law of conservation of mass as the mass of the reactants is same as that of the products.
Answer:
C. CH4 + 202 – CO2 + 2H20

A change in pH has the greatest impact on which life proces
Answer:
Aquatic Organisms
If the pH of water is too high or too low, the aquatic organisms living within it will die. pH can also affect the solubility and toxicity of chemicals and heavy metals in the water ¹². The majority of aquatic creatures prefer a pH range of 6.5-9.0, though some can live in water with pH levels outside of this range.
Explanation:
Adding more OH- ions increases the pH, making the substance more basic. Increasing the pH will increase the number of OH- ions, so the equilibrium will shift to the left. Decreasing the pH will increase the number of H3 O+ ions; they'll ''use up'' the OH- ions, thus shifting the equilibrium to the right.

Poultry products are a likely source of infection by:
Poultry products are a likely source of infection by Salmonella enterica
which causes typhoid.
Most farm animals such as pigs, cattle and poultry have been found to be
infected with Salmonella enterica as a result of their contact and exposure
to a dirty environment.
This is why it is advisable to apply much heat on poultry products such as
eggs to kill the micro-organism.

Explain why the shape of an enzyme is important to its function.
Answer:
The shape of an enzyme is very important because it has a direct effect on how it catalyzes a reaction.
Each enzyme is folded into a shape that allows the substrate(s) to fit into the active site, which is where the reaction occours. Other substrates do not fit into this active site. This is why each enzyme can only catalyse a specific reaction

What helps weaken atp bonds so energy can be released and then later help reform them?
Enzymes help weaken these bonds so energy can be released and then later help reform them.
that's the answer
ADP (adenosine diphosphate) is formed when these high-energy connections between the phosphate groups at the end are broken, releasing energy for the cells to utilize.
How is energy stored in ATP?One phosphate group is left on its own, these powerful associations may be broken and rebuilt with the aid of enzymes.
When a third phosphate is added to the ADP molecule, reforming ATP, water that was broken down into its hydrogen atom and hydroxyl group during ATP hydrolysis is recovered.
Energy must be introduced into the system to regenerate ATP, ADP develops and energy is released for the cells to utilize when these connections are broken.
Therefore, ATP has the capacity to store and transmit chemical energy, high-energy bonds are used to link the final two phosphate groups.

True or false? The effectiveness of an exchange surface is increased if there is a long diffusion path.
Answer:
True
Explanation:
The Long and Diffusion Path can Help the exchange surface to increased rapidly in a long diffusion path. in other words it grows faster.
If the diffusion path is long, the effectiveness of an exchange surface is improved is false.
What is diffusion?Diffusion is defined as the net movement from an area of higher concentration to an area of lower concentration caused on by the dispersal of any material's in-solution or gas-particle particles.
Diffusion is the process by which dissolved chemicals enter or exit cells.
What are the parameters that affect the diffusion?the three parameters that affect diffusion are
The concentration gradient. temperature.length of diffusion pathway.the membrane's surface area.The rate of diffusion increases with the magnitude of the concentration gradientThe rate of diffusion will increase as the temperature rises.Diffusion will occur at a faster rate if one cell membrane is larger than another.How may an exchange surface's effectiveness be enhanced?a wide surface area. a thin membrane to offer a short diffusion pathway. an effective blood supply.ventilation of the animals.learn more about diffusion here https://brainly.com/question/2135861

How were ozone levels monitored in 1920?
Answer:
I don't know
Explanation:
Sorry.. I really don't know

.
Help you later
Ozone levels in 1920 were primarily monitored using chemical methods, such as the use of chemical indicators and colorimetric analysis.
Potassium iodide-starch paper was used to detect ozone. When exposed to ozone, these indicators changed colour, letting researchers visually monitor ozone concentration.
Colorimetric analysis was also used. Chemical reagents reacting with ozone changed colour. Ozone concentration connected with colour change intensity. Chemical approaches measured ozone qualitatively or semi-quantitatively. They were easy to use but less precise than modern monitoring approaches.
In the following decades, spectrophotometry and ozone analyzers improved the systematic monitoring and quantitative measurement of ozone levels. These improvements made atmospheric ozone monitoring more precise.

Explanation:
The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins, as well as the introduction into the systemic circulation of various objects (small and large molecules, liquids, infectious agents, etc.), packed in delivery vehicles - exosomes and vesicles
The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins.
What is lipoprotein?Particles called lipoproteins are comprised of protein and fat (lipids). They deliver cholesterol to your cells through your bloodstream.
High-density lipoprotein, or "good" cholesterol, and low-density lipoprotein, or "bad" cholesterol, are the two main categories of lipoproteins.
LDL comes in the form of lipoprotein. These lipoproteins transport cholesterol to the artery cells. High levels of LDL particles can cause cholesterol to accumulate in your arteries and create blockages known as plaques. The term "hardening of the arteries" or atherosclerosis refers to this condition.
Therefore, The main role of the lymphatic system is the transport of cells of the immune system during the activation of immunity, lipids in the form of lipoproteins.
