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.
Answer:
The moment where the nuclear envelope forms at each pole spindle dissolves chromosomes uncoil is called Telophase.
Explanation:
In the eukaryotic cell, telophase is the final stage in meiosis and mitosis. In this step, the effects of prophase and prometaphase are reversed. This is the forth stage and a nuclear envelope forms at each pole. The spindle dissolves and the chromosomes uncoil, cytokinesis begins. The cell continues to enlogate.
Answer: Cell Membrane, Ribosomes, and Cell wall.
Explanation:
Answer:
Glaciers bring quantities of minerals beneficial to plants as the water runs off melting ice.
Explanation:
Glaciers are natural reservoirs of water and minerals that may persist to dry conditions during the summer season. Ice melting provides water and minerals during the warm season, which is therefore critical for plants living in dry summer environments. Moreover, it is well-known that the 'melt-water' (i.e., water released by the melting of glacial ice) also affects downstream stream water temperatures, creating a microhabitat that may be beneficial to the life of plant species.
Answer:
Honey
Explanation:
Technically it could be both, as they can both be acidic, but honey is lower on the pH scale, meaning it is more acidic and thus will have a larger chemical reaction with baking soda.
