What is a dichotomous key?

A dichotomous key is a tool developed by scientists to aid in the identification of objects and living things by both experts and laypeople. A dichotomous key often consists of a particular set of inquiries for recognizing a certain kind of object. The key instructs the user on what question to ask next once a question has been answered.

Since every species has a distinct scientific name, dichotomous keys frequently emphasize using it to identify species. In contrast, popular names for creatures like "penguin," "chipmunk," or "white oak" may apply to a wide variety of species that have a similar appearance.

For instance, a dichotomous key in tree identification would inquire as to whether the plant has leaves or needles. If the tree has leaves, the key then sends the user along one set of questions; if the tree has needles, another list of questions is presented.

Therefore the next step would be step 7.

The black panther phenotype in jaguars, which is a completely black coat, is thought to be determined by a single gene. If the presence of this phenotype were unrelated to habitat type, but was found to be much more common in populations in Costa Rica relative to populations in Brazil, what would be the most likely explanation for this geographic pattern

Answers

Answer:

Due to suitable climate and food availability.

Explanation:

The reason for this geographical distribution is the availability of suitable climate and food. Black panthers live in the hot, dense tropical rainforests environment where there is a lot of food present that is necessary for sustaining the population of black panthers. Black panthers are more common in Costa Rica as compared to populations in Brazil due to climate as well as food availability.

Answers

This should be the case ( YES )

Explanation:

This should be the case and

It would be objective as logical for adhesins to be glycoproteins and receptors to be protein as well and this is because adhesins ( cell surface component) fastens bacteria to their host body ,and they can be seen as glycoproteins because The structure of Adhesins are mostly made of structural protein

Glycoproteins are proteins which contain glycans.

Auxin moves to the darker side of the plant, causing the cells there to grow larger than corresponding cells on the lighter side of the plant. This produces a curving of the plant stem tip toward the light, a plant movement known as phototropism. Auxin also plays a role in maintaining apical dominance

Answers

Answer:

Im not sure sorry.

Explanation:

Proteins known as enzymes serve as catalysts in biological processes, accelerating the pace of chemical reactions. Several environmental conditions have an impact on an enzyme's effectiveness. The most crucial element is temperature.

The ideal temperature range for enzyme activity is typically between 30 and 40 degrees Celsius. The enzyme may lose its structure and, thus, its ability to perform when temperatures over this range cause it to become denatured. Another key aspect is pH; enzymes function best within a specific pH range.

The ionisation of the enzyme's amino acid residues can be impacted by pH, which will change the enzyme's structure and activity. Finally, the concentration of the substrate and the enzyme can influence the rate of the reaction along with the temperature.
