Increasing specialization of structure and function among animals of the same class or order for survival in new and different environments is called "phylogeny".
<u>Option: B</u>
<u>Explanation:</u>
- The analysis of evolution, diversity and the inter-connection among individuals or groups of organisms like species is understood as phylogeny.
- First one to apply the term phylogeny was German Biologist Ernst Heinrich Haeckel.
- With the help of estimation techniques of phylogenetic, such relationships were explored to test identified heritable traits, like DNA sequences or morphology under a framework of evolution of those characteristics.
- The detailing of species, their naming and grouping is understood as taxonomy. It is abundantly guided by phylogenetics, but maintains a field isolation from the scientific and logical.
- Based on the taxonomy school the extent to which taxonomies rely on phylogenies.
Answer:
The correct answer is - option A. Glass thermometer.
Explanation:
Glass or basal thermometers are the instruments that are use to measure temperature of any surface or organism. These are best choice for the measuring smaller changes in the temperature which can vary up to 1/10th of the degree to 1/100th of the degree.
In this case the temperature variation is 0.05 in the environment of the Toxicodendron diversilobum (poison oak) which can easily be monitor with the help of this glass temperature.
Thus, the correct answer is - option A. Glass thermometer.
A medical patient is suffering from mysterious fainting spells. A medical team works to get to the bottom of the problem and identify the cause. So the correct option is B.
<h3>What is the scientific method?</h3>
The start of a scientific investigation is observation. This means anything that catches the attention of the scientist. For example, for a cancer biologist, a certain kind of cancer might be an observation that can't be treated with chemotherapy and he would wonder why it is so.
For all the sciences, the core is a problem-solving approach which is called the scientific method. There are five basic steps in the scientific method. These are:
- Observation of a phenomenon
- Questioning the reason or cause for it.
- Hypothesizing or giving a testable explanation
- Making a prediction based on the hypothesis.
- Testing the prediction.
- Using the results to develop new hypotheses or predictions.
Therefore, the correct option is B.

Answer:
Ecosystems
Explanation:
An ecosystem is where the biotic and abiotic factors live. The other options only contain biotic factors.
Answer:
DNA polymerase.
Explanation:
DNA replication may be defined as the process of formation of daughter DNA from the template DNA strand. The process of DNA synthesis occurs in the 5' to 3' direction.
The enzyme responsible for DNA replication is DNA dependent DNA polymerase or DNA polymerase. This enzyme moves in 5' to 3' direction. DNA pol III is main replicating enzyme in prokaryotes and DNA pol alpha initiates DNA replication in eukaryotes.
Thus, the correct answer is option (a).
