Answer:

The benefits of genetic diversity include:

2- species survive despite negative mutations
4- species adapt to ever-changing environments
5-gene pool is strengthened

Explanation:

Mutations resulting from errors within gene replication frequently accumulate within species, becoming more stable over time. They lead to other forms of the same genes called alleles.

Several alleles within a population's gene pools leads to higher diversity. These may become beneficial, as the environment of the organism changes.

Mutations that confer benefits tend to help organisms survive and produce offspring, passing on these genes. However, some mutations may be deleterious/harmful and fatal. High diversity reduces the deleterious effects of some mutations on a population for a stronger gene pool i.e. the species survives.

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.

Which one of the biomes is considered endangered? What does this mean?

eimsori [14]

They must have a list of biomes there. When they say which one is endangered they mean which one is likely to no longer exsist after an amount of time.

The pattern of criss-crossing strips of pastry on top of food is called a what?

andriy [413]

The pattern of criss-crossing strips of pastry on top of food is called a quadriller. It can be done with the back of a knife such as fish, scallops, etc. Examples include: meat on the grill or criss-cross strips of pastry on top of a pie.
 The goal of the pattern is to improve food presentation and make it look more interesting.

Amoeba sisters: nature of science

Masteriza [31]

Answer:

The scientific mrthod is a process used by scientists to find answers to a question or to solve a problem. No there isn't just one because there are several versions of the scientific method. Some versions have more steps, while others may have only a few. Scientists can add steps, take out steps, revise, or make models.
