Answer;

A Both make it possible for the conditions in the interior to be different from the conditions outside.

Explanation;

Groups of molecules called microspheres may have preceded the living cells of today. Microspheres are tiny bubbles filled with groups of large organic molecules; they can form under very specific conditions. These microspheres may be a lot like the vesicles formed from the organic compounds taken off of the modern meteorites. Microspheres are not cells, but they do share some characteristics with cells.

These bundles of molecules are able to maintain an internal environment different from the surroundings outside the bubble. They also have a simple way of storing and releasing energy.  They expand by absorbing additional molecules until they reach an unstable size, and then they split into smaller microspheres. This division is not true reproduction or cell division, but it may be a precursor to it.

C) What does this cladogram tell you about the evolutionary relationship of the traits of jaws
schepotkina [342]

Answer:

In biology, a cladogram can be described as a diagram which shows evolutionary relationships among different organisms. A cladogram shows which organisms share evolutionary history and which organisms are more closely related to one another.

<em>The cladogram in the above picture shows that the limbs originated after the jaws. </em>

The cladogram shows that amoeba was a common ancestor to sponges, earthworms, salmon, lizards, kangroo and cats.

A chemical mutagen that is structurally similar to a nucleotide but has different base-pairing rules is called a ________.
OLga [1]

Answer:

Nucleoside analog

Explanation:

  • Nucleoside analogs are the mutagenic chemicals that have a structure that is similar to the normal bases of the nucleotide and thus can be incorporated in the DNA during the process of replication, however as it has different base-pairing rules than the normal nucleotide base it can lead to mutations.
  • An example of a nucleoside analog is acyclovir which an analog of guanosine.

What are the similarities between reproductive cells and body cells? Where are they found?
daser333 [38]

Organisms that reproduce sexually produce sex cells, or gametes, that carry a single set of chromosomes, the haploid number for the species. In contrast, body, or somatic, cells are the regular cells that form the organism’s tissues and organs. Somatic cells of sexual organisms have the diploid number of chromosomes, one set from each parent. Both cell types undergo mitosis, but only the primary reproductive cells, or gametocytes, also undergo meiosis.

Fossils layers 175 mya, 250 mya, 400 mya, 450 mya
Alenkinab [10]

450 mya, is where you would find fossils.

Explanation:

The first layer would be newer organismis that haven't quite decayed yet.The second and third layer is where the bones of the dead organasims lie, they havent quite been through the whole process yet, but they are nearly complete just about 100,000 years left.The fourth layers have been through alot, and have been there for many many years we can say abot 100,000,000 years.They are ready to become a fossil fuel.
