The best description of expression gene process is constitutive. this is because it is the partial diploid strain whereby the strain containing a beta-galactosidase gene which is constitutive.
Gene expression process is the process by which information from a gene is being used in the synthesis of the functional gene product. The process gene expression is used by different known life. For example, we eukaryotes, prokaryotes and utilized by viruses which are used to generate the macromolecular machinery which is for life.

What evidence suggests that vertebrates are more closely related to echinoderms than are any other invertebrate phyla?
VMariaS [17]

Answer:

Option C, shared DNA sequences

Explanation:

Complete question -

What evidence suggests that vertebrates are more closely related to echinoderms than are any other invertebrate phyla?  

- shared patterns of development

- shared morphology

- shared DNA sequences

Solution

Vertebrates have true backbone while invertebrates lack true backbone. Among the invertebrates, the echinoderm phylum is closely related to vertebrates as the echinoderm possesses notochord (similar to backbone) during their early stage development which disappears later.  

Through the genomic sequence studies it has been found that echinoderms are similar to vertebrates in many ways. Echinoderms have diverged from deuterostomes along with human and hence pose some genetic similarity  which can be devised through study of common DNA sequences

Hence, option C is correct

Fittoniya [83]

Answer:

The correct option is <em>C. Different species can share the same common name.</em>

Explanation:

A single organism might have the many common names or it might happen that different species have the same common name in different parts of the world. Common names can be sued when people from the same country, speaking the same language are talking.

But as scientific research is carried out in all parts of the world, scientists made up the system of binomial nomenclature. Under this system, each specie is given a unique name .

Please answer quickly!! Timed test! Which term is correctly paired with its role in the body? A) Insulin – a sugar that regulate
Nataly [62]

Answer:

The correct answer is -  D) Glucose – a sugar found in blood that can be broken down to produce ATP

Explanation:

Insulin is a hormone produced by the beta cells of pancrease that takes up the glucose from the bloodstram and make gucose available to the cells of the body to produce energy by the process of cellular respiartion. Glucose is breaken down to its smaller units and produced high amount of energy in the form of ATP. Glycogen is form of sugar that is stores in the muscle and othe cell for the energy in abscence or low glucose level in blood stream. ADP is a molecule know as adesnosine pyrophosphate or diphosphate which is play role in flow of energy. ADP molecules requires energy to form ATP molecule and when ATP splits into ADP and Pi releases high amount of energy.
