Answer:
Throughout the experiment at hand, the student will likely find that root space does indeed effect the length to which plantswill grow. Although I could not locate the table online, I will offer a general hypothesis for what the experiment will conclude. The student is testing the effects of root space on the way plants grow. The students experiment is well designed, keeping many variables constant and making sure that the amount of root spaceis the only difference between the plantsensures the accuracy of the experiment. Since we know that the experiment is well designed we are able to directly infer the effects of root space limitations without having to account for other factors. We can assume that the limited root space will in turn limit the extent to which a plant can grow. This is because plants need larger and deeper roots to support extended growth. Therefore, the plants in group Bwill grow smaller than those in group A.

Answer:
See the answer below
Explanation:
Recall that: <em>Water potential = pressure potential + solute potential</em>
Since the system is an open one;
<em>Water potential = solute potential = -iCRT</em>
i = number of particles the molecle will make in water (1)
C = molar concentration
R = Pressure constant = 0.0831 liter bar/mole K
T = temperature in kelvin = 22 + 273 = 295 K
To calculate water potential on side A:
C = 1 M
Water potential = - (1 x 1 x 0.0831 x 295) = -24.51 bars
For side B:
C = 2 M
Water potential = - (1 x 2 x 0.0831 x 295) = -49.03 bars
b.
<em>Since side A has higher water potential than side B, water will flow from side A to side B until equilibrium is established between the two sides. Water always flows from the region of higher water potential to the region of lower water potential.</em>

Answer:
Why are embryos used in medical research?
Stem cells can be obtained at the early stages of embryo development; these cells are called human embryonic stem cells (hESC). They also could be used in research to develop drugs to treat serious diseases, or to repair organs following a stroke or heart attack.
b)1 unicellular- means one cell
Answer:
D.dragonfly larvae
Explanation:
For example ;
This is a simple food chain;
algae ⇒ mosquito larvae ⇒dragon fly larvae ⇒perch
Algae are the producers in the food chain above.
Mosquito larvae are the primary consumer in the above food chain.
Dragonfly larvae is the secondary consumer in the food chain which feed on the primary consumer.
The final level is perch, which is a carnivore .
