Answer:

The sodium-potassium pump is an active transporter because it needs to move sodium and potassium ions against the concentration gradient.

Explanation:

You have to think of it as outside vs inside the cell.

Outside the cell, you have 5mM K and 150mM Na. Inside the cell, you have 100mM K and 10mM sodium. Without the transporter then the ions would go from greater concentration to lower concentration.  Energy keeps the ions going from the way they would naturally happen.

Sewage and stormwater discharge are the two ways E.coli is introduced into the rivers.

Briefly explain how municipalities can solve the E.coli problem.

Chlorine, ultraviolet radiation, or ozone can all be used to treat water to kill or inactivate E.coli, especially when the water comes from a private source like a well. It is necessary to disinfect systems that use surface water sources to remove all bacterial contamination.

Our rivers can get contaminated with E.coli through a variety of sources and entry points, including sewage and stormwater discharges or runoff from urban and agricultural areas, seepage from malfunctioning septic tanks, and direct deposition by livestock and wild animals.

Hence, E.coli is introduced into rivers by sewage and stormwater discharge.

The correct ordering of the steps of DNA transcription is as follows:

Step #1: DNA unzips

Step #2: RNA polymerase binds to the promoter region at the start of

the gene

Step # 3: Using DNA as a template, complimentary RNA bases are linked to form mRNA

Step #4: mRNA is released and DNA "re-zips"

Step #5: mRNA leaves the nucleus through the nuclear pore

DNA transcription is the process by which a region of the DNA called a gene, which contains the information about making a protein is used to make an mRNA molecule.

The mRNA molecule is then used to synthesize proteins at the sites of protein synthesis in the cytoplasm called the ribosomes.

The enzyme that is responsible for the synthesis of mRNA from a DNA template is called RNA polymerase.

Choose the corresponding number. (The answer is explained in the explanation in the biological terms).

Explanation:

The label that points to the part of the ATP synthase that is like the blades of a turbine is labeled "F1." The F1 component of ATP synthase contains the catalytic sites responsible for synthesizing ATP, and it rotates like a turbine to drive the synthesis of ATP. Similarly to how the blades of a turbine are moved by water or wind, the F1 component is rotated by the flow of protons through the enzyme, which generates the energy needed to produce ATP.

The life cycle of a typical bony fish involves several stages. These stages include the egg, larva, juvenile, and adult stages.

Below is the description of the basic life cycle of a typical bony fish:

Stage 1: EggThe first stage of the life cycle of a typical bony fish is the egg stage. In this stage, the eggs of bony fish are released by the female fish and are fertilized by the sperm of the male fish. After fertilization, the eggs are usually transparent and have a gel-like coating that serves to protect them from predators.

Stage 2: Larva After the egg stage, the fish undergoes a larval stage, in which the fish hatches from the egg. In this stage, the fish is still transparent and very small. At this stage, the fish starts to grow and develops into a juvenile fish. The larva is usually free-swimming and feeds on plankton.

Stage 3: Juvenile Stage three is the juvenile stage. At this stage, the fish starts to resemble an adult fish in terms of appearance. The fish is usually larger, has developed fins and a tail, and starts to feed on small aquatic organisms. The juvenile fish moves into freshwater habitats.

Stage 4: Adult Stage four is the adult stage. At this stage, the fish is sexually mature and can reproduce. The adult fish feeds on larger organisms and can grow to be a considerable size. At this stage, the fish can also migrate to the ocean or to other water bodies to spawn.

The given statement "enveloped viruses are released from the host cell by lysing the host cell which results in immediate cell death." is False.

Enveloped viruses:

Enveloped viruses can be released from the host cell by both lytic and non-lytic processes, such as the budding process. The budding process allows the virus to exit the host cell without immediately causing cell death. During the budding process, the virus acquires its envelope from the host cell membrane, and the newly formed virus particles then leave the cell. This process allows the host cell to remain alive and continue producing more viruses. Lysis of host cell refers to the destruction of the cell, which is more commonly associated with non-enveloped viruses.

The carbon 'that makes up organic molecules in plants is derived directly from b. carbon fixed in photosynthesis.

During photosynthesis, plants take in carbon dioxide from the atmosphere and use it to synthesize organic molecules, such as sugars, starches, and cellulose. The carbon in these organic molecules comes directly from the carbon dioxide that the plant has fixed during photosynthesis.

Respiration, on the other hand, releases carbon dioxide into the atmosphere as a byproduct, so it does not directly contribute to the carbon that makes up organic molecules in plants.

While the lithosphere does contain carbon in the form of minerals and fossil fuels like coal, plants do not directly incorporate this carbon into their organic molecules. However, when fossil fuels are burned, they release carbon dioxide into the atmosphere, which can then be used by plants during photosynthesis.
