According to scientific evidence, earth’s earliest atmosphere lacked oxygen. Over time, oxygen was added to the atmosphere.Which statements explain how this change occurred and how it affected life on earth?

Choose all answers that are correct.

A.

Adding oxygen to earth's atmosphere allowed for the development of prokaryotic organisms, which need oxygen to carry out many of their life processes.

B.

Adding oxygen to earth's atmosphere allowed for the development of eukaryotic organisms, which need oxygen to carry out many of their life processes.

C.

Oxygen is needed to carry out photosynthesis. When cyanobacteria evolved, they began to carry out photosynthesis.

Explanation:

Georgia's overall coastal habitats were rated and the results can be seen in the bar graph. The coastal habitats by in large were rated as "fair". One important indicator in the graph is the chlorophyll a category. Explain how the ratings for chlorophyll a might influence the overall ratings of coastal habitats. A) The algae that contains chlorophyll a can be detrimental to other life forms. As algae increase the total organic carbon increases. B) The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develop, C) Chlorophyll, a plant pigment, is measured to indicate the amount of algae in the water. The more chlorophyll a present, the more plant growth and the healthier the aquatic environment. D) There is a direct correlation between algae present and benthic organisms. The more algae, the more benthic invertebrates. That means more abundant food for other animals in the coastal habitats.

Answers

Answer:

The answer is:B) The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develop.

Explanation:

"Eutrophication" is the enrichment of surface waters with nutrients for plants, both nitrogen and phosphorus contribute to eutrophication.

A lake with total concentrations of phosphorus and chlorophyll-a of 10 and 2.5 mg / m3 respectively, can be classified into different eutrophication classes.

The symptoms and effects of eutrophication are as follows:

· Increased production and biomass of phytoplankton, associated algae and macrophytes.

· Production of toxins by certain algae.

· Deoxygenation of water, especially at the end of algal growth situations.

Answer:

Explanation:

The more chlorophyll a present, the more algae present. This can be a result of higher nitrogen and phosphorus and may result in lowered dissolved oxygen if algal blooms develops. periodt pooh

For the following scenarios, Determine if the virus, causing the disease is generally a lyric cycle or a lysogenic cycle

After being exposed to the influenza virus, a teenager begins to show symptoms after 4 to 7 days

Answers

Answer:

lytic cycle involves the reproduction of viruses using a host cell to manufacture more viruses; the viruses then burst out of the cell. The lysogenic cycle involves the incorporation of the viral genome into the host cell genome, infecting it from within

Explanation:

Final answer:

The influenza virus primarily follows the lytic cycle, causing rapid replication and destruction of host cells.

Explanation:

The influenza virus primarily follows the lytic cycle. After being exposed to the virus, a teenager begins to show symptoms after 4 to 7 days. During the lytic cycle, the virus infects a host cell and takes over the cell's machinery to produce more viral particles. This leads to rapid viral replication within the host cell. As the virus replicates, it eventually causes the host cell to burst, releasing the newly formed viruses. This process results in the destruction of the host cell and the spread of the virus to other cells in the body.
