This fish is called a jawless fish because it doesnt have any scales
Answer:
The correct option is C. Drawing a conclusion
Explanation:
The scientific method can be described as a method through which all the scientific questions are tried to be answered.
The scientific method begins with a question. To answer the question, a hypothesis is generated. Experiments and observations are made to test the hypothesis. Based on the data from experiments and observations, conclusions are drawn. Hence, the statement 'based on the data, we determined that plant growth is affected by the type of soil' best illustrates a conclusion.
Answer:
Each cell in your body has DNA, but the DNA formation was influenced by your parents. Their genes formed your genes.
Answer:
D. the need for a surface area of sufficient area to allow the cell's function
Explanation:
Many cellular functions such as the exchange of substances and respiratory gases, absorption of nutrients, cell-cell communication, etc. require the cells to have a sufficient surface area. A small cell has a larger surface area to volume ratio and therefore, maintains a higher rate of exchange of substances. As the cell increases in size, the surface area grows less than its volume. Therefore, the surface area required to perform the cellular functions puts an upper limit on the cell size.
Cells maintain the required surface area by dividing and/or by developing folding or projections on the surface. For instance, the cells in the wall of the small intestine require to maintain a higher surface area for nutrient absorption. Therefore, the cells of the wall of the small intestine develop microvilli to have a larger surface area which in turn supports a relatively higher rate of absorption.
<u>The structural differences between prokaryotes and eukaryotes:</u>
The main differences between the prokaryotes and eukaryotes are the presence of nucleus in the eukaryotic cells and its absence of nuleus in prokaryotes.
Also, prokaryotes are single-celled, so that a cell is a whole organism. On the other hand, eukaryotes are mostly multi cellular, and therefore more complex. More complex DNA is in the nucleus in eukaryotic cells, that allow them to carry out a wide range of functions. Prokaryotes, as a single cell, have the features of simple present.
