Which of these types of organisms undergo the procell

A random mutation occurs and the GGA codon is changed to GGU. What effect does this substitution have on the amino acid being ca

salantis [7]

Answer:

Instead of arginine codon, proline condon would be coded.

Explanation:

GCA encodes codes for glycine while on the other hand codon to GGU, GGC, or GGG encodes for glycine.

This substitution will lead to generation of complementary code “Proline” in the complementary mRNA or DNA strand.

The codon CCT, CCC, CCA, CCG encodes for proline. If this mutation would not have occurred then Arginine would have been encoded in the complementary codon with base structure of CGT, CGC, CGA, CGG

organize the terms isotonic, hypertonic, and hypotonic in order from the solution with the lowest concentration of dissolved par

8_murik_8 [283]

Hypotonic, isotonic, hypertonic
these terms are connected to the solution concentration. hypotonic solution is the solution with low concentration (lower than the concentration of particles in the living cell of an organism). if you put a cell in such solution, that cell would baloon because of the water migrating inside willing to rebalance the concentrations. isotonic solution is the solution with concentration of particles equal to the concentration inside a cell. hypertonic solution has concentration of particles higher than a cell and putting cell in this solution makes it shrivelled because of the water flowing outside (willing to rebalance concentrations again).
that's a phenomenon of osmosis.

What ecological level consists of all the ecosystems found on earth?

Wittaler [7]

Answer:

Levels of organization in ecology include the population, community, ecosystem, and biosphere. An ecosystem is all the living things in an area interacting with all of the abiotic parts of the environment.

Explanation:

Hope this helps! :)

The theory of endosymbiosis suggests that chloroplasts and mitochondria were once free-living prokaryotes, that were engulfed by

Drupady [299]

The question is incomplete. The rest of the question is : Which of these is not supported by the endosymbiosis theory concerning organelles?

A) contain DNA.

B) contain ribosomes.

C) are capable of living independently.

D) are surrounded by a double membrane.

Answer:

Option C) are capable of living independently is not supported by the endosymbiosis theory concerning organelles

Explanation:

The endosymbiosis theory proves that chloroplasts and mitochondria were prokaryotic cells before due to many reasons. Some of which are:

These organelles have their own separate DNA.
The separate DNA present in them is capable of making their own proteins.
They are membrane- bound organelles.

However, these organelles can now not live separately outside of the cell. This might be because of the evolutionary changes which occurred in these cells during the long period of time.
