HELPP me please I’ll give brainliest if two people answer!!!!

The soda contains CO2 that is dissolved CO2 reacts with water

CO2+H2O--->H2CO3

to form carbonic acid

this is a weak acid but it gives protons to water

H2CO3+H2O-->-HCO3+H30+

pH=-lg[H3O+]

[H3O+] is the molar concentration

Therefore the acid present in the solution causes the pH to be lower than 7. It can either be the H2CO3 if it is a carbonated beverage or citric acid from lime juice.

Answer:

Using 'immobilized algae'

Explanation:

Photosynthesis is an important biochemical process in which plants, algae, and some bacteria use the energy of solar radiation as a source of energy for food synthesis.

Immobilized algae are used to standardize the amount of photosynthetic tissue in any investigation.

Trace evidence: In addition to fingerprints, small measurable amounts of materials, such as hair, fibers, and bodily fluids (blood, urine, and so on), are also found at a crime scene. These materials can help investigators link a perpetrator or victim to the crime scene.

Answer: diffusion of ions as a result of their concentration gradients.

Explanation:

Resting membrane potential can be defined as the basic charge of the cell. It is defined by the concentration difference between the ions due to the action of the ion pumps. The differential permeability of the membrane is because of the charge on the ions and leads to the creation of the ion channels. The negative charged ions accumulate on the inner side of the cell.

Answer:

The correct answer is "Red shift"

Explanation:

Blue shift: When the source and observer approach one another, the evident frequency increments or apparent wavelength diminishes. Here the Doppler shift is positive. This is known as blue shift.

Red shift: When the source and observer move away from one another, the clear frequency diminishes or apparent wavelength increments. Here the Doppler shift is negative. This is known as red shift.

Answer:

Genetic Modification is a procedure to change the qualities of a plant, creature or miniature life form by moving a bit of DNA from one living being to an alternate living being. This is done through focused expulsion of the ideal qualities from the DNA of one living being and adding them to the next living being. This strategy has for instance been utilized to create growths and microorganisms that produce drugs.

Evolution is the cycle by which current creatures have dropped from old progenitors. Evolution is liable for both the surprising similitude we see over all life and the astonishing variety of that life.

Explanation:

Evolution is change in the heritable qualities of organic populaces over progressive ages. These attributes are the statements of qualities that are given from parent to posterity during generation. Various attributes will in general exist inside some random populace because of transformation, hereditary recombination and different wellsprings of hereditary variety. Evolution happens when transformative cycles, for example, regular choice (counting sexual choice) and hereditary float follow up on this variety, bringing about specific qualities getting more normal or uncommon inside a populace.

It is this cycle of development that has offered ascend to biodiversity at each degree of natural association, including the degrees of species, singular life forms and atoms.

Explanation:

DNA → mRNA → Protein (b)

Answer:

1.0 mole per dm3 sodium chloride solution

Explanation:

The more the molarity of a solution, the lower the water potential of the solution, and the higher the amount of water that will osmotically move from the potato stick to the solution when placed in it in order for an equilibrium to be established.

Hence, the 1.0 mole per dm3 sodium chloride solution will cause the largest decrease in the mass of the potato stick when compared to the 0.5 and 0.1 mole per dm3 sodium chloride solutions.

Answer:

the outcome of a frame shift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA strand in terms of condons,or groups of three nucleotides. theses groups are called the reading frame.

Explanation:

hope that helps.:)

Changing one mRNA codon will change a protein because each protein

have their specific mRNA codons.

The mRNA codon are translated into a single amino acid during polypeptide

formation.  Changing one mRNA codon will result in the formation of a

different type of protein.

The mRNA codon comprises of three base pairs and a change in an amino

acid such as Alanine which has a codon of GCA which when replaced by

GAC will form aspartic acid.

Answer:

A. ) To transfer hereditary information

Explanation:

The least likely function of lipids in plants and animals is to transfer hereditary information. Thus, the correct option for this question is A.

Lipids may be defined as a type of chemically diverse group of organic compounds that are insoluble in water but are readily soluble in non-polar solvents like benzene, chloroform, ether, etc.

The classical functions of biological lipids include the following:

The biomolecules or compounds that significantly deal with the function of transferring biological and hereditary information are known as proteins.

Therefore, transferring hereditary information is one of the least likely functions of lipids in plants and animals. Thus, the correct option for this question is A.

Answer:

D. They define geological periods because scientists use them as reference points for  tracking the history of the earth.

Explanation:

Catastrophic events related to changes in geological timeline are very useful in defining geological periods.

These events have very significant appearance in the geological record and can be used to determine the history of the earth.

The catastrophic events usually culminates into extinction cycles or termination of some organisms from the earth surface.

Geologists use these events that are often wide spread to delineate geological periods.

Answer:

sharks

Explanation:

Because they are the ones to get the last bit of energy. Secondary consumers are the group in the food chain that eats primary consumers. This means that secondary consumers can either be omnivores or carnivores. These terms refer to whether or not they eat just meat or a varied diet. Secondary consumers don't need to have a specific diet.

The energy pyramid is a representation of the producers and consumers along with the flow of energy. The sharks will be at the top of the energy pyramid. Thus, option C is correct.

An energy pyramid is a graphical representation of the biomass of the producers and the consumers of the ecosystem. It consists of the trophic levels that have designated producers, primary consumers, and secondary consumers.

A producer is at the bottom of any energy pyramid as they produce the foods for the primary consumers that are most likely herbivores. The secondary or the tertiary consumers are at the top.

Therefore, option C. sharks being secondary consumers are at the top of the pyramid.
