There would be hiccups when the motor branches of ventral
rami associated with the C3-C5 region of the spinal cord is damage. Irritation of the phrenic nerve may cause
diaphragm spasms called hiccups. Dorsal
and ventral rami are similar in that they both contain sensory and motor
fibers.
The protease enzyme pepsin is found in the stomach and has a highly acidic PH of just 2, so the line would be at PH 2, so lower down than amylase which has a PH 7 :)
Answer:
Many years ago scientists believed that protein, DNA is not the genetic material because of many reasons like DNA is made up of only four type of nucleotides while proteins are made up of 20 different types of amino acids. So the building blocks of protein are way high than DNA.
Most of the cellular function is performed by proteins, not DNA. The three-dimensional shape of protein is much higher than nucleic acid. So as protein heterogeneity was high therefore it was considered as a molecule of genetic information instead of DNA.
Answer:
a) Toxic (gases)
d) Bacterial
Explanation:
Septic tanks are underground structures usually built with concrete or plastic in which wastewater is treated. These tanks are generally used in rural areas and are located near bathrooms and laundry rooms.
If a septic tank is working correctly, it should produce any unpleasing smell. However, when an individual perceives a certain strong bad smell it could be due to the presence of gases (low levels of hydrogen sulfide and high levels of carbon dioxide, and methane) and anaerobic microorganisms such as sulfur bacteria which also produce methane and, therefore, strong smell.
It all depends of what kind of bad smell is the person perceiving. For example, the smell of "rotten egg" is usually due to microbial pollution and gases. Although these gases are not toxic in low levels, they could become highly toxic. It is extremely important to pay attention to smell and give the appropriate mainteinance.
