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>
Answer:
If the disorder has an autosomal recessive inheritance pattern, according to the family tree both parents do not have the disorder, but are carriers.
Explanation:
When a disorder or disease is recessive it requires<u> two alleles with the disorder to manifest</u>. In this case, according to the pedigree, both parents must be heterozygous carriers and not present the disorder.
<u>Parents
</u>
♂ Dd
♀ Dd
Both without disorder but presenting the altered gene, which makes them carriers.
<em>Alleles D d
</em>
<em>D DD Dd
</em>
<em>d Dd dd</em>
The offspring of these parents have a 50% chance of being carriers without the disorder, 25% non-carriers, and 25% with the disorder.
In the event that either parent was DD, there would be a 50% chance of carriers without the disorder and no chance of offspring with the disorder, which has a recessive inheritance pattern.
The nurse is caring for an infant with bacterial meningitis. The etiology would the nurse consider as the most likely route of transmission to the central nervous system is cranial aperture or sinuses.
Bacterial meningitis is the infection in which the membrane of the brain and spinal cord is effected. This can cause swelling and press against the brain or spinal cord which can even cause life threatening conditions.
Common bacteria that can cause meningitis are Stretococcus pneumonia, Haemophilus influenza, Neisseria meningitidis.
Infant with bacterial meningitis have vomiting, seizures and irritability. The most likely cause of contamination for the disease may come from cranial aperture or sinuses.

Answer:
Percent error = 8.3%
Explanation:
Given data:
Accepted value of specific gravity = 7.2
Measured value of specific gravity = 7.8
Percent error = ?
Solution:
Percent error = measured value - accepted value / accepted value × 100
Now we will put the values in formula.
Percent error = 7.8 - 7.2/7.2 × 100
Percent error = 0.6/7.2 × 100
Percent error = 0.083 × 100
Percent error = 8.3%
