Answer:
See explanation.
Explanation:
Hello.
In this case we can for instance take into account the following mixtures:
- Orange juice.
- Tea.
- A soda.
- Salty water
- Coffee.
Thus, since the orange juice is a suspension as long as it contains different sizes of orange pulp particles that cannot be dissolved mostly because of its organic nature.
Tea can be a solution when we place a tea bag in a cup with warm water since just soluble components of tea are successfully dissolved in the water. Moreover, homemade tea based on some plants are fruits may behave as a suspension due to the oraginic particles that are not dissolved in the water yet suspended.
A soda is a solution of some water-soluble compounds, gaseous soluble carbon dioxide and water which are homogeneously distributed in the solution.
Salty water can be a solution if you put some salt in warm or just cold water and wait until it dissolves completely.
Coffee can be also a solution or suspension depending on how it is made, which type of coffee is used and the amount of coffee added to the hot water.
Best regards.

What organism can carry out cellular Respiration
Answer:
Organisms from all kingdoms of life.
Explanation:
Including; bacteria, fungi, plants etc.
Organisms like bacteria, plants, fungi can carry out cellular respiration.
What do you mean by cellular respiration?Cellular respiration is the process by which biological fuels are oxidised in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP.
Cellular respiration is a series of chemical reactions that break down glucose to produce ATP, which may be used as energy to power many reactions throughout the body.
The reactions of cellular respiration can be grouped into three stages: glycolysis (stage 1), the Krebs cycle, also called the citric acid cycle (stage 2), and electron transport (stage 3).

Describe the convention currents that occur inside earth. Why are they rotating?
Answer:
Convection currents are defined as the transfer of heat due to the bulk movement of molecules within fluids.
From past experiences, we know that heat rises. When a liquid is heated from the bottom, it will rise to the top. To take the place of the previously heated liquid, the colder liquid that was at the top before will move to the bottom and will be heated. Then that will rise to the top and the cooler liquid that was being heated first will move beck to the bottom to be heated again. The earth's heat source is from the core, which is towards the bottom if youre looking at the mantle. So the same principle applies there as well.

•They "key" is the substrate
Explanation:
Meaning that only the accurate key size(substrate) will fit into the keyhole of the lock(enzymes).
In 1937, a man employed to lay water pipes was found to be the source of a severe epidemic of typhoid fever. The man, an asymptomatic carrier of Salmonella enterica serotype Typhi, the bacterium that causes typhoid, habitually urinated at his job site. In the process, he contaminated the town’s water supply with bacteria from his bladder. Over 300 cases of typhoid fever developed, and 43 people died before the man was identified as the carrier.
Given that antibiotics were not generally available in 1937, how could health officials end the epidemic, short of removing the man from the job site?
Answer:
They could lay new water pipes.

which of the following is NOT a characteristic of eukaryotic cells?
A nucleus
DNA in the cytoplasm
Membrane-bound organelles
Answer:
DNA in the cytoplasm
Explanation:
Prokaryotic cells are defined by the lack of membrane-bound organelles and a defined nucleus. Instead, the cell's processes take place in the cytoplasm. The cell's DNA is also found in the cytoplasm.
Eukaryotic cells are the opposite - they are defined by the presence of a defined nucleus and membrane-bound organelles, such as mitochondria, endoplasmic reticulum, and lysosomes. The genomic DNA is found inside the nucleus, not the cytoplasm.

List and discuss ten (10) activities within your watershed that can result in pollution of the rivers in the watershed.
Answer:
The ten activities that can result in the contamination of the rivers of a watershed are:
Mining. Metallurgical Industry. Oil extraction. Hospitals and other medical services. Agriculture. Livestock. Tourism. Tanneries. Final disposal of solid waste. Production of electrical energy.Explanation:
Mining, depending on the type of mineral that is extracted, can incorporate extremely dangerous substances such as cyanide or mercury into adjacent rivers, which are sometimes used for gold extraction.
The metallurgical industry does not usually dispose of its solid waste ineffectively, however, there is a big problem with its discharges, which are usually loaded with different metal ions that are disposed of in water sources and increase their load.
Oil extraction has demonstrated its great potential for contamination of water sources thanks to the fracking method, by which the rock is broken for the extraction of gas and oil, however, in turn, water sources, both underground and surface, are contaminated, to the point that water is flammable due to its high content of these products in it.
Hospitals and other medical services tend to have discharges with a high organic load, which if they were disposed of in rivers could greatly contaminate them, in addition to other by-products of this activity such as pathological residues could become a big problem if they were not disposed of a correct way.
Agriculture regularly uses fertilizers that can be carried to water sources due to runoff, causing problems such as eutrophication.
In the event that intensive but extensive livestock farming is not carried out, where the livestock travels in large areas and even approaches water sources to drink water, there is a high probability that the water will be contaminated by their excrement, being disposed of within the same water source or transported by runoff.
Not all tourists have good habits, there are tourists who take walks or other activities in open areas without any care, leaving solid waste near the rivers of the basin or even contaminated after performing their physiological needs.
Tanneries use elements such as chromium in their processes, which has a high probability of reaching adjacent rivers and greatly polluting them.
Solid waste constitutes a serious pressure problem for soil and water, whether its origin is domestic or industrial, poor disposal of it can cause its final destination to be a river, polluting it and reducing the diluted oxygen there which in turn destroys the aquatic fauna of the place.
The production of conventional electrical energy, regardless of the method used, has serious impacts on water sources: Thermoelectric plants make use of water at room temperature which returns to high temperatures (despite using cooling ponds), plants Hydroelectric plants pause the river's route causing an oxygen deficit at the base of the river and therefore no aquatic life, finally, with nuclear plants, there is the possibility that the waste from such activity is not properly contained and ends up contaminating sources underground and surface areas of the sector.

Answer:
select what ever u want from below
Explanation:
Prokaryotes are organisms made up of cells that lack a cell nucleus or any membrane-encased organelles. This means the genetic material DNA in prokaryotes is not bound within a nucleus. In addition, the DNA is less structured in prokaryotes than in eukaryotes: in prokaryotes, DNA is a single loop while in Eukaryotes DNA is organized into chromosomes. Most prokaryotes are made up of just a single cell (unicellular) but there are a few that are made of collections of cells (multicellular).
Scientists have divided the prokaryotes into two groups, the Bacteria, and the Archaea. Some bacteria, including E Coli, Salmonella, and Listeria, are found in foods and can cause disease;1 others are actually helpful to human digestion and other functions.2 Archaea were discovered to be a unique life form which is capable of living indefinitely in extreme environments such as hydrothermal vents or arctic ice.
A typical prokaryotic cell might contain the following parts:
Cell wall: the membrane surrounding and protecting the cell
Cytoplasm: all of the material inside a cell except the nucleus
Flagella and pili: protein-based filaments found on the outside of some prokaryotic cells
Nucleoid: a nucleus-like region of the cell where genetic material is kept
Plasmid: a small molecule of DNA that can reproduce independently
Eukaryotes
Eukaryotes are organisms made up of cells that possess a membrane-bound nucleus (that holds DNA in the form of chromosomes) as well as membrane-bound organelles. Eukaryotic organisms may be multicellular or single-celled organisms. All animals are eukaryotes. Other eukaryotes include plants, fungi, and protists.
A typical eukaryotic cell is surrounded by a plasma membrane and contains many different structures and organelles with a variety of functions. Examples include the chromosomes (a structure of nucleic acids and protein which carry genetic information in the form of genes), and the mitochondria (often described as the "powerhouse of the cell").
