Rachel wants to test how sunlight impacts plant growth over time she will add billing amount of light to different sets of plans
ahrayia [7]

Answer: sunlight.

Explanation: When trying to establish the level or extent of correlation or relationship which exists between two variables, the variables are classed as independent and dependent variables. The independent variable is referred to as the variable which causes a change in the value of the other variable (dependent variable). It is also known as the explanatory or predictor variable as it lead to changes in the dependent or predicted variable. In the scenario above, the independent variable is sunlight whose impact leads to changes in the growth level of the plant.

Which of the following scenarios is an example of temporal isolation?
DedPeter [7]

Answer:

B. Black-eyed Susans and daisies used to be part of the same species. A random mutation in a subset of a population caused one group to release their pollen three weeks before the other, causing interbreeding to cease.

Explanation:

Temporal isolation, where temporal relates to time. So temporal isolation is the process where two populations will reproduce at different times/different seasons and therefore cause a split in species. In this case, we see the flowers release pollen at different times and caused a split into two distinct species.

During osmosis, which of the following will occur if the left side of a selectively permeable membrane has a higher solute conce
storchak [24]

Explanation:

Water molecules from the less conentrated right side, will flow into the left side til they equilibrate- at equilibrium both sides will have the same concentration of solute.

In diffusion small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. Similarly, during osmosis the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid bilayer, this means that the water moves from regions of high osmotic pressure/concentration to regions of low osmotic pressure /concentration.
