Biology
1 answer:
Zigmanuir [339]3 years ago
3 0
The geochemical cycle which involves mantle convection is the tectonic cycle. The tectonic cycle involves the movement of the Earth’s crust. It is through the mantle convection that the plate tectonics move. The movements inside the mantle influence how the plates move on the earth’s surface, which contributes to the formation of landforms.

If you measure the rate of respiration of plant root hair cells, would you expect it to be the same as, more than, or less than
DaniilM [7]

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>

Nady [450]

The emission of N2O from the landfill site is called denitrification and it is caused by the action of denitrifying bacteria.

<h3>What is dissolved oxygen?</h3>

The term dissolved oxygen refers to the amount of oxygen that is present in  a water body. Now, we know that the addition of organic matter into water requires oxygen to break it own thus the dissolved oxygen content will go down in response to the added organic load.

The process that leads to the emission of N2O from the landfill site is called denitrification and it is caused by the action of denitrifying bacteria.
