Fertilizers have nutrients that help plants grow. Sometimes, when it rains, fertilizers are washed away from farmland into ponds

and lakes. This promotes the growth of algae, a type of plant, present in the water. It is observed that algae grow very fast and cover the surface of the pond completely. They use up all the dissolved oxygen in the pond. How does this affect the other organisms in the pond

Answer:

They do not get enough oxygen, and die.

Explanation:

When fertilizer flows into rivers and lakes, they trigger the process of eutrophication, which is the increased concentration of nutrients in the water environment. This high concentration of nutrients encourages the overproduction of algae that often completely covers the surface of the aquatic environment.

The large amount of nutrients, also increased by the death of these algae, helps in reproduction and exaggerated increase of aerobic bacteria. By using oxygen in their breathing, these bacteria end up consuming a large amount of this gas, which causes the death of several other species, such as fish and other aquatic beings. It is noteworthy that, with the lack of oxygen, aerobic bacteria also end up dying.

In addition, excessive algae build-up forms a layer that prevents sunlight from passing through, which consequently affects the photosynthesis process performed by algae and aquatic plants. This causes the death of photosynthetic organisms that are not located in the most superficial layers.

Answer:

B) They do not get enough oxygen, and die.

Explanation:

They loose oxygen due to the algae. The algae bloom uses up all the O2 in the plant structures .

So the plant cells can maximize the amount of ______ that they each get
Ymorist [56]

Answer:

Depends...

Explanation:

You need to include more information regarding the question. If the question is referring to the roots of the plant then the answer would be water. If the questions asks about the area of the leaves/amount of leaves then it would be sunlight. If the question is talking about stomatal pores then it would be carbon dioxide.

Hope this helps,

type a paragraph describing how the circulatory and respiratory systems work together to deliver oxygen to the body tissue and r
ch4aika [34]
The circulatory or cardiovascular system's ability to deliver oxygen throughout the body depends on proper functioning of the respiratory system. The interactions between the cardiovascular and respiratory systems are best demonstrated by following the path of a red blood cell starting in the heart and traveling through the lungs.

A red blood cell that has just returned from delivering oxygen and that has brought back carbon dioxide would be in the right upper chamber of the heart or in the right atrium. When the atrium contracts, the cell is pumped into the right lower chamber of the heart, or the right ventricle. When that ventricle contracts, the red blood cell is pumped out of the heart through the pulmonary artery to the lungs.

In the lungs, the red blood cell enters tiny blood vessels that come into close contact with the walls of the alveoli air sacs of the lungs. The carbon dioxide in the red blood cell passes through the walls into the alveoli while the oxygen in the alveoli air passes into the red blood cell. The red blood cell then returns to the heart via the pulmonary vein.

From the pulmonary vein, the red blood cell enters the left atrium of the heart and then the left ventricle. The part of the heart muscle powering the left ventricle is very strong because it has to push the blood out to the whole body. The red blood cell is pumped out of the left ventricle via the aorta artery and eventually reaches the capillaries leading to the individual cells. There the cells absorb the oxygen from the red blood cell and pass on their waste carbon dioxide. The red blood cell returns to the right atrium of the heart via the veins to complete the cycle.

These circulatory and respiratory system interactions are ones that humans and higher animals such as mammals and birds share and that represent one of the basic functions of their bodies. Only when these two systems work and interact properly can the human or animal carry out other functions such as looking for food or reproducing.

The frontal lobes also include the primary ____________ which controls voluntary motor functions.
lakkis [162]

Answer:

The correct answer will be- primary motor cortex

Explanation:

The motor cortex is the portion of the brain present in the precentral gyrus of the frontal lobe of the brain.  The motor cortex is thought to be involved in the planning actions and control voluntary actions.

The motor cortex is divided into three regions: premotor cortex, primary motor cortex  and supplementary motor area.

The primary motor cortex is the region of the motor cortex which controls the voluntary movements in the human body by generating the impulse.

Thus, the primary motor cortex is the correct answer.
