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.

A dog eats a pound of dog food. What happens to the energy and chemical nutrients in the food over the next several days?
Black_prince [1.1K]

Answer:

The energy is mostly released as heat through the dog's activities; the nutrients either become part of the dog's body or are released to the ecosystem as wastes like urine, feces, and exhaled gases.

Explanation:

  • The food that is consumed by an organism is digested and the nutrients obtained from the food are partly absorbed by the digestive system and assimilated and stored into the body and the nutrients that are not absorbed are released in the form of feces.
  • The chemical energy obtained from the food is released in the form of heat through the activities that are done by the dog.

A cell biologist treated some cells with a stain. She found that the stain was concentrated within the mitochondria of many type
larisa [96]
A

B is wrong because mitochondria would likely absorb the stain even if it was dead.(And most cells that have been treated are dead anyway). C and D are just throwaway answers, you usually want to avoid the word "always" when drawing conclusions.
