<span>If the middle groin was not constructed then there would be more erosion between the first and last groin. The middle groin must be constructed in order to fix the erosion between the two groins. If the first or the last groin was not constructed then the erosion will be less compared to the middle groin.</span>
Abiotic<span> variables found in terrestrial ecosystems can include things like rain, wind, temperature, altitude, soil, pollution, nutrients, pH, types of soil, and sunlight.

<h2>
Option (B) is Right Answer</h2>
Explanation:
(B) chromatids are attached to one another
- <em>The linkage between the sister chromatids </em>is particularly critical at centromeres because it ensures right <em>microtubule connection to the kinetochores </em>
- In eukaryotes, a centromere is a district of DNA that is responsible for the development of the imitated chromosomes into the<em> two daughter cells during mitosis and meiosis</em>
- There is one centromere on every <em>chromosome and centromeres are responsible for two major functions</em>
- In eukaryotes, a centromere is a district of DNA that is responsible for the development of the imitated chromosomes into the <em>two daughter cells during mitosis and meiosis</em>
Answer:
C
Explanation:
The experimental and control group differ by <u>only one factor</u> for a scientist, and that is the independent variable.
<em>A scientist will always try to isolate the effects that are due to a variable and keep every other variable constant. The variable that is manipulated in order to measure its effect is known as the independent variable. A control group usually forms the basis for measuring the effects of the independent variable. While the independent variable is varied in experimental groups, it kept at the zero level for the control group.</em>
The correct option is, therefore, C.
Answer:
identify the variables
Explanation:
control:type of lemon used
dependent:whether apple slice turns brown at pH>2
independent:pH value
