A is the answer. You would need soil with different amounts- including no amount- to determine how the fertilizer affects the plants
Since you are measuring the height a ruler would be a good idea as well.

Answer:
-Sensors in the brain detect a lack of oxygen.
-The muscles in his body need more energy and therefore more oxygen.
Explanation:
-Sensors in the brain detect a lack of oxygen.
-The muscles in his body need more energy and therefore more oxygen.
-The body has too little carbon dioxide to maintain function.
-The body is using carbon dioxide instead of oxygen to make energy.
-Blood pressure has decreased, so less blood is being pumped to the muscles.
<em>The correct answer would be that </em><em>sensors in the brain detect a lack of oxygen</em><em> and t</em><em>he muscles in the body of Jon need more energy and therefore, more oxygen.</em>
At sea level, the atmospheric pressure easily allow oxygen to permeate the cells of the lung and diffuse into the blood. At high altitudes, air pressure is generally lower and permeation/diffusion through the cells of the lung into the blood becomes difficult.
<u>Without adequate oxygen, the body cannot generate energy needed for physical activities of muscles. Consequently, the sensors in the brain detect a lack of oxygen and the body system reacts by breathing heavily to compensate for the oxygen shortage.</u>
The changes that one can expect to observe as a plant tissue culture develops is the development of new shoots and root.
<h3>What is a Culture?</h3>
This refers to the process in which microorganisms, living matter etc are grown in a specially prepared nutrient medium which are made up of different types of compounds.
In the case of a plant tissue culture, there will be new shoot and root formation due to the presence of nutrients in which the plants are exposed to for its growth and survival.
This is therefore makes changes in the shoot and root be the most appropriate choice.

Answer:
Secondary Consumers
Explanation:
If the larvae eat the needles, they are the primary consumers and herbivores. Because they eat the larvae, the birds become the secondary consumer. Tertiary consumers are at the top of the food chain, and eat secondary consumers and primary consumers. Primary producers are energy producing things like plants, etc.
