The cells that make up the xylem are adapted to their function: They lose their end walls so the xylem forms a continuous, hollow tube. They become strengthened by a substance called lignin . Lignin gives strength and support to the plant.

Use the principles of diffusion to explain why oxygen molecules in the tissues of the lung go into the blood
Keith_Richards [23]

Answer:

Oxygen molecules in the tissues of the lung diffuse into the blood because the concentration of oxygen in the lung's tissues is more than the concentration of oxygen in the blood.

Explanation:

Diffusion is the movement of molecules from the region of higher concentration of the molecule to the region of lower concentration of the same molecule. Molecules in diffusion move <em>downward the concentration</em> <em>gradient</em> created by difference in concentration between two regions until an <em>equilibrium (equal concentration in the two regions)</em> is established.

Oxygen molecules diffuse into the tissues of the lung when an organism breathes-in during the process of breathing. The molecules in the now oxygen-rich tissues eventually start diffusing into the blood in the lung because the blood passing through the lung is always de-oxygenated or has lower oxygen concentration compared to the tissues of the lung.

Oxygenated blood moves into the heart, pumps round the body by the heart, gets depleted of oxygen and eventually find its way back to the lung where the process is repeated.

Diffusion of oxygen from the tissues of the lung into the blood will keep happening as long as oxygen keeps getting dissolved into the lung's tissues and an equilibrium is yet to be established between the tissues and the blood.

Meg drew this model to show the carbon cycle. However, there are errors in her model. Which arrows point in the wrong direction?
Rus_ich [418]
Factory Emissions is going in the wrong direction. The arrow should be pointing upward, as factory emissions release carbon into the atmosphere.

Answer:

The correct option is D: Faults form because crust gets cracked when plates move apart along divergent plate boundaries.

Explanation:

Options A and B are incorrect because even though tectonic plates are constantly moving and crashing against each other at convergent plate boundaries, it is not responsible for causing an earthquake. Option C is also incorrect in the context of the question statement merely colliding does not result in an earthquake.

Hope that answers the question, have a great day!

How can I set up a wildflower classification key?
s344n2d4d5 [400]

Answer:

There are 3 methods to set up a wildflower classification means discovering a new flower. Those methods are discussed below in the explanation section.

Explanation:

Method one (Identification tools using):

  1. Search the about of the flower in the flower dictionary or flower database.
  2. Use any app which can identify flower such as Flowerchecker, Naturegate, etc.
  3. Take photos of the plant and post it on Flicker to get more information.
  4. Try google photos for searching about the plant by its picture.

Method two( Measuring the physical character of the plant):

  1. Measure the overall height of the plant.
  2. Measuring the width of the plant.
  3. Look at the flower to check how the flower is arranged on the stem.
  4. Count the petal number of the flower.
  5. Identify the color of the petals.
  6. Check the shape and texture of the stem.
  7. Check the shape, size, and arrangement of the leaves in the plant.
  8. Use this collected information to identify the flower in a plant database or encyclopedia.

Method three (Identifying the Flower’s Location and Blooming Time):

  1. Use the climate and terrain to determine the type of the flower.
  2. Observation of the factors in the geographic location to identify the flower.
  3. Find out the time of year when the flower bloomed.
  4. Identify the flower in an online database or encyclopedia using the collected information.

By doing this, you can set up a wildflower classification key and can find out the kingdom, family etc of the flower.
