What change could a student measure to collect data about the rate of photosynthesis in a certain type of algae when it is expos
Alborosie

Answer:

A student can measure the number of gas bubbles given off by the algae.

Explanation:

  • Photosynthesis is the process where green plants convert light energy into the fuel energy for their development and activities.
  • Algae is also involved in the photosynthesis process, so the it releases the gas bubbles.
  • The oxygen emission process is done by secreting the bubbles by green plants during photosynthesis process.
  • So to know about the  photosynthesis rate the number gas bubbles, really helps a lot.

(1)

Troposphere – This is the densest layer and where weather events occur

Stratosphere – This is where the ozone layer is found. Some high altitude aircraft cruise in this layer.

Mesosphere – Temperatures drop with altitude in this layer

Thermosphere – This is where most of the meteorites that enter the earth’s atmosphere burn up. This layer takes up most of the Uv and X-rays from the sun. Most satellites orbiting earth are in this layer

Exosphere – almost akin to space due to the thinness of the layer. Molecules in the layer often escape into space

(2)

A ‘pause’ is a transition between the above-mentioned distinct layers. The tropopause, for example, occurs between the troposphere and the stratosphere and the stratopause between the stratosphere and mesosphere and thermopause is found between thermosphere and exosphere.

(3)

A temperature inversion is a rise in temperatures with altitude in a layer in the atmosphere. One layer exhibiting temperature inversion is the stratosphere. This is due to the ozone layer that absorbs UV light. The upper ozone absorbs most of the UV light, than lower ozone, exciting the molecules and making the higher altitudes in the layer to be warmer.

(4)

The ozone layer protects life on earth from the high energy UV radiation from the sun. UV is capable of causing double-stranded break on DNA resulting in genetic mutations on organisms. Most of these would be lethal. The Ozone absorbs most of the UV before it reaches earth's surface. Ozone is formed when an oxygen molecule reacts with another oxygen atom to form an O₃. The oxygen atoms are made from the splitting of an oxygen molecule by UV light.
