A would be correct. It’s the hardest mineral.
The answer to this question would be: risk taking
In this case, the nurse <span>finds that one of the prescribed drugs is redundant and notifies the primary healthcare provider. To recognize the drug as redundant the nurse should have read some source about that drug. The nurse notifies the primary health care in hope to changes the medication. It was a risk-taking attitude since that means the nurse willing to take the risk to implement the knowledge.</span>
Answer:
This question lacks options, options are: a.related. b. homologous. c protein-coding, d. comparative. The correct answer is b.
Explanation:
Homology refers to the fact in which the sequences of two or more proteins or nucleic acids are very similar due to the fact that they have the same evolutionary origin. Normally two sequences have a high similarity because they are homologous, that is, they share a common ancestor.
If two sequences in an alignment are from a common ancestor, mismatches can be interpreted as point mutations (substitutions), and gaps as insertion or deletion mutations introduced into one or both lineages in the time since they diverged.
<u>Answer:</u>
The scientist is viweing cnidarian, because it has gut.
<u>Explanation:</u>
The gastrovascular gut is the essential organ of assimilation and dissemination in two noteworthy creature phyla: the Cnidaria (counting jellyfish and corals) and Platyhelminthes (flatworms). The cavity might be broadly spread into an arrangement of channels.
In cnidarians, the gastrovascular framework is otherwise called the coelenteron, and is usually known as a "visually impaired gut" or "visually impaired sac", since nourishment enters and waste exits through a similar hole.
<h2>Cell Cycle
</h2>
Explanation:
Eukaryotes grow and divide by cell cycle.
The main parts of a cell cycle are an ordered series of events – Gap 1 or G1 phase, Synthesis or S phase, Gap 2 or G2 phase, and the mitosis or M phases.
Interphase period (G1, S, G2 phases) - cell grows by size, duplicates its content, replicates its DNA, and finally prepares for mitotic cell division
.
Mitosis and cytokinesis - formation of two identical daughter cells
Cell cycle is regulated by regulatory or restrictive checkpoints in the cell cycle which are activated with detection of a defective DNA.
Proliferation of undesired or cells with defective DNA like in case of tumor cells is controlled by the action of suppressing agents like p53 and cyclins.
The tumor suppressor gene protein p53 prohibits division of tumor cells. Cyclins regulate cell cycle by activation of the enzyme cyclin-dependent kinase.
