The independent variable in the hypothesis of an observed increased in sea turtle sickness once an increase in red tide can be seen would be the increase of red tide.
The reason for this is that red tide increases or decreases will happen independently of the amount of sea turtle sickness - therefore increasing sea turtle sickness will be dependent on the first variable. (independent one).
Answer:
The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".
In plants, there are two types of respiration: dark respiration and photo respiration. The first kind occurs in the presence or absence of light, while the second occurs exclusively in the presence of light.<em>Plant respiration occurs 24 hours per day</em>, but <em>night respiration is more evident since the photosynthesis process ceases.</em> During the night, it is very important that the <em>temperature is cooler than during the day</em> because plants can experience stress. Imagine a runner in a marathon.
roots respire too!
One of the functions of the substrate is <em>to serve as a site for air exchange between the root zone and atmosphere</em>. In other words, <em>roots breathe oxygen like we do</em>. Different plants have different oxygen requirements for their root systems.
For example,
<em><u>the root system of a poinsettia requires a lot of oxygen, so it is best to use a substrate with high air porosity, while hostas can live well in a substrate with a high water holding capacity. </u></em>
<h3><em><u>C.</u></em><em><u> </u></em><em><u>This cell has no nucleus.</u></em></h3>
Because bacterial cell do not have a well-defined nuclear membrane. The coiled DNA particles lie naked in the cytoplasm. This is called nucleoid. While in animal cells the nucleus is surrounded by a well-defined nuclear membrane.
Answer:
shivering
Explanation:
the movement of your muscles creates friction between them, which produces heat, thus warming our bodies up.
<span>Emperor Penguins huddle together during the winter without eating - they have eaten before the winter and they live of their saved fat during this time - so the answer won't have to do with food. The correct answer is B) - they move back to the exterior (or are pushed by other penguins) - only like this can all the penguins survive the winter, by cooperation, rather than being selfish.</span>
