stealth61 [152]2 years ago
8 0

Answer:

A

Explanation:

The color does not define a substance, as a lot of things can be different colors.

A chemical property isn't always what causes the color.

Many substances are that same color.

The color can change for various reasons.

The p. multocida that are growing within sam's abscess are breaking glucose down via glycolysis in order to obtain energy. this
Evgen [1.6K]

Answer: The enzyme increases the effectiveness of reactant collisions thereby increasing the number of reactant molecules that reach activation energy.

A reaction occur if the substrates needed collide with each other. Enzyme is like a mold that can hold the substrate so that it will be easier to collide. The effect of enzyme could be seen in the activation energy needed to do the reaction because enzyme lower it very much. This will help speed up the reaction so it create product faster.

g Select true statements about three‑dimensional protein structures and their evolutionary relationships. Every species has only
vesna_86 [32]

Answer:

Every species has only unique proteins. FALSE

Determining sequence homology is an important tool for predicting protein structure and function. TRUE

Protein function is directly related to the protein's tertiary structure. TRUE

Protein function can be predicted from amino acid sequence. TRUE

The tertiary structure of a protein is more highly conserved than the primary structure. TRUE

Explanation:

Every species has only unique proteins. FALSE

There are homolog proteins among species, that share ancestry. It can be for a speciaton events, and this are called orthologs, or due a gene duplication event, and this are called paralogs.  

Determining sequence homology is an important tool for predicting protein structure and function. TRUE

Sequence homology of an unknown protein can be useful since the primary structure can be used for modeling the protein structure, and also this information can be compared with databases of proteins of known function and retrieve predictive information about this protein function. Proteins with similar amino acid sequence usually do similar biochemical functions.

Protein function is directly related to the protein's tertiary structure. TRUE

In most cases, structure dictates the biochemical function of the protein. Protein functions are as diverse as protein structures.

Protein function can be predicted from amino acid sequence. TRUE

The primary structure (sequence of aminoacids) can lead to the elucidation of the secondary and tertiary structure of the proteins, since the sequence of the residues, and the nature of them (hydrophobic, aromatic, hydrophilic, basic, etc). This will shape the tridimensional form of the protein.

The tertiary structure of a protein is more highly conserved than the primary structure. TRUE

There can be changes in the amino acid sequences, but if they are amino acids of the same family, they will interact similar and maintain the tertiary structure with minimum changes.

What are the differences between aggregate fruit and multiple fruit ​
Dmitry_Shevchenko [17]

Answer:

Aggregate fruit is a fruit that develops from several ovaries forming one flower. An example of an aggregate fruit is a raspberry. Multiple fruit is fruit that develops from a cluster of flowers, and each flower produces a fruit, which turns into a mass of a singular fruit. An example of multiple fruit is a pineapple. Each "cube" of a pineapple is a separate fruit formed from a single flower, yet the pineapple as a whole is one mass of pineapple.
