Answer:

evacuate all wildlife from the bay

Explanation:

Algal bloom is a term used to describe the excessive growth of algae species in a water body. This excessive growth or proliferation is as a result of the exposure to nutrient in form of pollutants, a process called Eutrophication.

However, the presence of an algal bloom indicates the pollution of that water body, which will result in the degradation of the pollutants by bacteria. As bacteria acts on the pollutants in the water body, they excessively use the dissolved oxygen of the water body, hence, drastically reducing the oxygen levels of the water. This possess a great threat to aerobic wildlife in the water, which could die as a result of suffocation or anorexia.

Hence, the most important thing to do in a case of noticing an algal bloom in a bay is to evacuate all wildlife from the bay in order to prevent mass death.

Identify the characteristics of a cell. Check all that apply. measures 3-500 micrometers infects all forms of living cells grows
TiliK225 [7]

Answer:

A cell is defined as the structural and functional unit of an organism.

The average size of the prokaryotic cell lies between 0.1 to 10 micrometers whereas the average size of the eukaryotic cell is approximately 25 micrometers.

Four things are found in all the cells: genetic material (either DNA or RNA), cell membrane, cytoplasm, and the ribosome.

All the living cells grow and reproduce (sexually or asexually) and have the ability to respond to stimuli.

Thus, characteristics of a cell may include: cell grows and reproduces, responds to stimuli, contains DNA or RNA, not both , and contains a cell membrane.

Define the five systems. Be sure to include enough information to distinguish each system from the others. (Site 1)
VladimirAG [237]
By definition, a body system is primarily comprised of different organs and tissues that work one another to achieve a common body process. These body systems would include:

Circulatory system - concerns with the circulation of blood
Digestive system - breaking down of food particles 
Skeletal system - composed of bone structures serving as our body's framework
Nervous system - composed of nerve cells that responds to different stimuli
Respiratory system - concerns of utilising the entry of oxygen and the exhalation of carbon dioxide.

Mafic lava tends to have low silica content. Based on this, which of the following statements about mafic lava is most likely tr
sashaice [31]

Answer:

A. It contains fewer volatile gases.

Explanation:

Mafic lava have a composition of about 45-55% silica with high amount of Fe, Mg, Ca.

The silica content is quite low compared to those of granitic magma whose silica content can reach up to about 60%.

What determines the viscosity of magma is basically the silica content of the magma and the temperature of the magma. Viscosity is the resistance to flow.

The higher the silica content, the lower the viscosity and the higher the amount of volatile gases. Such type of magma is the granitic magma. Granitic magma due to their viscosity flows slowly.

The lower the silica content, the higher the viscosity and the lesser the presence of volatile gases in them. Such an example is Mafic magma. Mafic magma flows very slowly with low amount of dissolved gases.

devlian [24]

Answer:

C: competitive exclusion

Explanation:

<em>The competitive exclusion principle states that organisms living in the same community while competing for the same resources cannot coexist at a constant population rate. </em>

Once some of the species within the community get a slight competitive edge over other species, they become dominant and this might lead to the extinction of the weaker species in the long run.

<u>In the experimental plot, the removal of sea stars provided mussel and barnacle with a competitive advantage over other species within the community (sea stars are predators of mussels and barnacles). This led to the dominance of mussel and barnacle and the eventual extinction of other species within the experimental plot as compared to the control plot.</u>

The correct answer is C.
