1. If a girl carved her initials in the trunk of a maple tree at a point five feet above the ground twenty years ago, and the tree grew at a rate of one foot per year, where can she expect to find her initials today?

2. Describe two mechanisms that move water from the roots to the upper portions of a plant. Indicate the restrictions of each. Which method is more effective in larger, taller plants?

3. Name six species of plants that have leaves. For each plant state whether they are a monocot or dicot. Then for each species state whether their leaves are simple or compound. Then state if their venation is parallel, netted palmate, or netted pinnate. Lastly, state if their leaf arrangement is alternate, opposite, or whorled. (Can you please set this up in a chart with five columns and six rows so I can compare the different plants)

1. Since the shoot of a plant (including the trunk of a tree) grows vertically from apical meristems (primary meristems), the initials will remain in the same place where she originally carved them. The shoot grows from its extending its top, not by pushing up from the bottom.

2. Transpiration is the evaporation of water from a plant (mostly from the leaves). This evaporation removes water from the air spaces in the leaves, which causes a water deficit in the air spaces. This water deficit is made up by water moving from the cells into the air spaces. But this then caused a water deficit in the cells. As a result, water from the adjacent ...

Solution Summary

Transpiration and pressure-flow are discussed in this post.

I am trying to find the partial pressure of ethylene for this equation. The reaction is ethylene polymerization, i.e., ethylene to products which is first order in partial pressure of ethylene:
The flow rate of 5% ethylene/He (balance) in gas phase is 50 mL/min for a small laboratory downward reactor tube made up of quartz.

This job creates a flow diagram to illustrate the reflex pathway by which atrial natriuretic factor helps regulate blood volume following an increase in blood volume.

1. Calculate the following.
a. 100 ml of liquid A has a mass of 250 g. What is its density, in kg/L? (Note: 1 L = 1000 ml = 0.001 m3)
b. Liquid B has a specific gravity of 0.98. How much does 1 L weigh, in an Earth-standard gravitational field?
2. The pipe shown above expands from an internal diameter of 3 cm to an

1. A laboratory receives a sample of a metallic alloy composed of aluminum and magnesium. The sample is a solid cylinder with a diameter of 2 cm and a length of 5 cm. Its mass is 15.70 g. What is its density? What is its specific gravity?
2. A boat has a dry weight of 3500 lbs. How many liters of water does it displace?

I can see that a Darcy's law permeability equation exists and is as follows:
k = (volume of liquid x length of specimen)/(time of flow x cross-sectional area of specimen x deltaP)
In this equation, there are 2 parameters that I do not understand
1) When the equation refers to the "time of flow" (t) what is meant by that?

A liquid with a density of 1.37*10^3 kg/m^3 flows through two horizontal sections of tubing joined end to end. In the first section, the cross sectional area is 10.4cm^2, the flow speed is 276cm/sec, and the pressure is 1.42*10^5 Pa. In the second section, the cross sectional area is 2.71cm^2.
