Which trial in the table of data shown has questionable data

Biology
1 answer:
Serga [27]3 years ago
5 0

<u>Answer</u>: dataset Z

The genus of aquatic plants known as Elodea is composed of 6 species that are also called waterweeds. Native to South and North America, these plants are very popular in aquariums.

The table in the image presents the stem growth of plant stems in 22 days. In three of the trials, the stems grow constantly. However, in dataset Z the growth reaches a maximum in day 15, followed by a decrease in day 22.

As nothing additional is mentioned in the question about the presence of any possible species that may feed on these plants, this decrease is anomalous. As it is absent in the other trials, it is safe to assume that a measurement error has occurred. Thus, dataset Z has questionable data.

Commuters drive personal vehicles to their places of work: offices, manufacturing plants etc.

Some may use car pooling or mass transit like buses. But too many want the luxury and convenience of coming and going on their own terms.

IMHO car pooling and mass transit needs to be used more to reduce environmental harm.

What are the differences between prokaryotic and eukaryotic cells? Focus on cells from microscopy lab?
pishuonlain [190]

Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example of prokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.

There are several key differences between prokaryotic and eukaryotic cells. Eukaryotic cells are found in multicellular plants and animals, whereas prokaryotic cells are found in bacteria and archaea which are ususlly unicellular. I have summarised the key differences below:

Prokayotic cells do not have membrane-bound organelles, such as the endoplasmic reticulum or mitochondria.

Prokaryotic cells do not have a nucleus, instead they have circular DNA that is free in the cytoplasm.

Prokaryotic cells have smaller ribosomes than eukaryotic cells.

Prokaryotic cells have a cell wall. Their cell wall is made from a different material to a plant cell, a glycoprotein called murein.

Prokaryotic cells may also have a protective layer called a capsule, flagellum to aid in movement and one or more plasmids.
