ANTONII [103]3 years ago
6 0

Answer:

Amphibians begin their lives as eggs, The few eggs that get fertilized, and survive will hatch in 7-9 days. After the eggs of an Amphibian hatch they are called Tadpoles. Tadpoles breathe through gills like fish. ... Metamorphosis is the final process that changes the amphibian from tadpole to adult.

Answer:

valence electrons an element has in its outer shell, the easier it is to complete.

The most electron shells an element has, the easier it is to fill its outermost shell.

Explanation:

Non metals atoms bond to other elements by sharing or completing the valance electrons in other element. This is easily made when the other element lacks a small number of electrons, for example with Hydrogen it has 1 valance electron because of that it is easier to bond with other elements.

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.
