marusya05 [52]

Answer: Matter and Energy

Explanation:

The producers make food by the help of the process known as photosynthesis.This is the way by which the energy from the sun is transferred from sun to the plants.

Matter is made and transferred from one tropic level to another tropic level. The organic matter is transferred from the producers to the consumers.

The primary consumer converts energy from them to the secondary consumers.

So, the conclusion is that matter and energy is transferred from one tropic level to another tropic level.

Metagenomics (check all that apply): Group of answer choices Can leverage Next Generation Sequencing technology to identify and
ikadub [295]

Answer:

- Can leverage Next Generation Sequencing technology to identify and characterize organisms

- Has resources to support analysis at the DOE-JGI site.  

- Can identify microbiologic organisms without traditional isolation and culturing of individual organisms.

Explanation:

Metagenomics can be defined as the study of whole genomes of biological communities recovered from environmental samples. This genomic field has enabled the discovery of new species (microorganisms) and their effects on the environment. Next-Generation Sequencing (NGS) technologies allow to obtain huge amounts of genomic data, which has been a limitation in genomics and metagenomics. Metagenomic NGS (mNGS) is a technique used for sequencing nucleic acids present in a biological sample containing mixed populations of microorganisms. Finally, the Department of Energy Joint Genome Institute (DOE JGI) is a referent in metagenomic analysis, especially in genome assembly data obtained from microbial communities. This Science User Facility has developed a series of bioinformatics tools and databases in order to analyze metagenomic information.
