Alenkinab [10]3 years ago
7 0

Answer:

The correct answer is - 1000:1

Explanation:

Prokaryotic cells are unicellular organism of the domain prokaryotes and archaea. These cells lacks cell organelles however other components such as plasma membrane, cytoplasm and DNA. The size of the prokaryotic cell ranges between 0.1 to 5.0 µm.

On other hand eukaryotic cells also contain cellular structure like plasma membrane DNA , cytoplasm but also include true nucleus and other cell organelles that are double membrane bounded. The average cell size of these cells are tend to be - 10 to 100 of the cell size

Thus, the correct answer is - 1000:1.

In three to five sentences, explain why recyclable does not necessarily equate to renewable. Give examples to support your expla
Anika [276]

Recycle and renew are the two R's that uses and transforms the waste material. Recyclables do not equate to renewable as recyclable materials do not occur naturally.

<h3>What are recyclable and renewable?</h3>

Recyclable is the resources that are used finite times over and over and undergo a certain process for re-use purposes.  They can be naturally or by humans, processed to be used again.

Renewable is resources that are natural and are replenished in nature when gets decreased by natural processes.

Some recyclables like aluminum and glass are not renewable as they are not formed naturally and do not get replenished by natural processes.

Therefore, recyclables are not renewables.

What was known before Franklin and Wilkins conducted their studies of DNA? Check all that apply. DNA is found in the nucleus of
kvasek [131]

Answer:

The correct answer will be-

   1. DNA is found in the nucleus of a cell

    2. Organisms store and transmit genetic information

    3. Cells contain protein molecules.

Explanation:

The study of DNA started much before the discoveries of Rosalind Franklin and Maurice Wilkins.

Nucleus of cell was discovered by Robert Brown in 1831 but the material present inside the nucleus called "nuclein" (DNA) came from the studies of Johann Friedrich Miescher in 1869.

Proteins as a constituent of cell were discovered by the experimental analysis of Gerhardus Johannes Mulder in 1837.

DNA as a genetic material came from the experimental studies of Frederick Griffith in 1928, Oswald Avery, Maclyn McCarty, and Colin MacLeod in 1944, and Hershey and Chase in 1952.

Franklin and Maurice Wilkins are known for their work on the the structure of DNA as they were able to produce high-resolution X-ray photographs of DNA fibres called Photo 51 in 1952 using X-ray diffraction technique. By 1953 Franklin concluded concluded that DNA shows helical structure with phosphates on outer side.

Thus, 1. DNA is found in the nucleus of a cell

         2. Organisms store and transmit genetic information

         3. Cells contain protein molecules.

             are the correct options.

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.

Where does the urea in the urine come from?
Vesnalui [34]

Answer:

Urea is produced when foods containing protein, such as meat, poultry, and certain vegetables, are broken down in the body. Urea is carried in the bloodstream to the kidneys, where it is removed along with water and other wastes in the form of urine.
