Answer:
water is what earth is mainly made of. our bodies are also mainly water.
Soil scientists use the capital letters O, A, B, C, and E to identify the master soil horizons<span>, and lowercase letters for distinctions of these horizons. Most soils have three major horizons: the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but such a horizon can also be buried. The master horizon, E, is used for subsurface horizons that have a significant loss of minerals (eluviation). Hard bedrock, which is not soil, uses the letter R.</span>

Motor coretex is essential for receiving information that you are moving your legs.
<h3>What is motor cortex?</h3>
- The motor cortex's main job is to provide signals that control how the body moves. It is anterior to the central sulcus and a portion of the frontal lobe.
- The primary motor cortex, premotor cortex, and supplementary motor area make up this region.
- The motor cortex generates signals that are particular to movements and sends them to the muscles via spinal cord circuits and motoneurons to regulate motor behavior.
- For the execution of movements to be precise, coordinated muscle activation patterns are required.

Answer:
Constant variables
Explanation:
Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:
1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.
2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.
3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.
