Biology

o-na [289]4 years ago

Cyanobacteria are the major force of the Great Oxygenation Event around 2.35 billion years ago. The organisms that evolved photosynthesis changed the composition of the atmosphere to mainly oxygen. This changed the dynamic of life on earth by allowing organisms to also exist on land. This is because it was possible for ozone to form and reduce the lethal UV rays from the sun reaching the earth's surface to destroy genetic material.

<h3><u>Answer</u>;</h3>

Because oxygen atmosphere that organisms such as human beings depend on was generated from them.

<h3><u>Explanation</u>;</h3>
  • Cyanobacteria are aquatic and photosynthetic,which means they live in the water, and can manufacture their own food.
  • <em><u>Cyanobacteria have been  important in shaping the course of evolution and ecological change throughout earth's history. </u></em>
  • <em><u>The oxygen atmosphere that we depend on was generated by numerous cyanobacteria during the Archaean and Proterozoic Eras. Before this time, the atmosphere had a very different chemistry, unsuitable for life as we know it today.</u></em>

Plants are autotrophic can you think of some plants that are partially heterotrophic.
Stels [109]

There exist some insectivorous plants like the Pitcher plant, Venus flytrap plant, etc that are considered to be partially heterotrophic.

<h3>What are insectivorous plants? </h3>

The insectivorous plant which is sometimes also referred to as a carnivorous plant is a plant that has a special adaptation for the capturing and digesting of insects.

They can also digest some other animals by the means of unique structures like ingenious pitfalls and traps. Carnivorous nature in plants is an independent evolution and is present about six times throughout the several families and orders of plants.

There are more than 600 known species of carnivorous plants and they make for a very diverse group. In some cases, they have some more characteristics than their carnivorous nature.

Therefore, the Pitcher plant, Venus flytrap, etc are considered to be partially heterotrophic plants.

Which of the following statements does NOT describe a vertebrate eye?
Scrat [10]

The correct answer is: d. it contains many light-sensing columns called ommatidia

Ommatidia are units that form compound eyes of arthropods such as insects, crustaceans and millipedes (these are invertebrates) and make them very sensitive to motion. Ommatidia are composed of photoreceptor cells (visual detection) surrounded by support cells and pigment cells.

The eyes of vertebrates are more complex showing that progressive improvements in the structure of the eye occurred during the evolution.
