Answer:
Water in the geosphere can be discharged into surface water, becoming part of the hydrosphere once again, or it could be drawn up into the roots of a plant and become part of the biosphere. Water in the biosphere can be released into the atmosphere through transpiration in plants, or respiration in animals.
Answer:
Cancer cells are characterized by mutations associated with the uncontrolled growth of these tumor cells
Explanation:
Mutations in tumor suppressor genes are often associated with different types of cancers. On the other hand, mutations derived from the insertion of Transposable Elements may also activate cancer-related genes which are known as oncogenes
Answer:
answer is d) all of these choices are correct.
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>
