Answer: salt

Freshwater is defined as having a low salt concentration, usually less than 1%.

Explanation:

Freshwater refers to the bodies of water that contain very low levels of dissolved salts. So, freshwater are unique for their low salt content (about 0.5% of salt) compared to the sea water with high salt content.

Examples of freshwater include rivers and spring

What happens during cellular respiration?
mylen [45]

Answer:

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate (ATP), and then release waste products. The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen, are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.

Create an experiment where you would use both a Southern blot and a Northern blot to determine if a newly isolated bacterium con
natta225 [31]

Answer:

■Gene sequences would be used to make Probes for both the Southern and Northern blots.

■The probes will be used to view the presence of each gene with the use of isolated genomic DNA obtained from the isolated bacterium

■Each probes hybridized to the genome shows the pathway is isolated and point of the genes were involved in the substrate catabolism

■The carbon source in the isolate is derived from the substrate inducing the catabolic pathway as RNA determine transcripts present

■Probes hybridizing to the same sequences would be used to determine the gene activity for the pathway as seen in the southern one

■since all the genes present in the genome couldn't be identified, the northern would be important to work on

■Catabolic pathway is determined by the same genes. Hence, the need for gene/transcript probes to hybridize to the transcriptome.

PLEASE HELP!! i need help with this for biology i’m desperate please

As per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.

<h3>What is Genetic material?</h3>

Genetic material may be defined as any substance found in the cells of plants, animals, microbial or other origins that hold genetic information and that departs it from one generation to the next.

In 1944, Avery and others concluded that the transforming material was pure DNA, not protein or RNA.

These investigators found that DNA extracted from a virulent strain of the bacterium Pneumococcus genetically transformed an avirulent strain of the organism into a virulent form.

Therefore, as per the demonstration of Griffith and Avery, it can be concluded that the given experiment finding supports hypothesis III, i.e. genetic material or transforming substance is DNA.

To learn more about Griffith's experiment, refer to the link:

The correct genotypes of the parents are <span>AaBb and Aabb

In a cross of these two genotypes presented in the image below, 5/8 of the offspring would be deaf.
The individuals marked with a red square would be deaf because of the recessive aa alleles and the rest of the progeny that is marked with green would be deaf because of the presence of the B dominant allele.</span>
