Answer:
2) The phospholipid head groups would likely have equal numbers of positively and negatively charged groups that would pack well and not be bulky.
Explanation:
Benzene contains aromatic groups making it non-polar while the phopholipid head contains the negatively charged phosphate group making it polar. These molecules would repel each other forcing the phopholipid head to be in the inner membrane forming. The hydrophobic non-polar phospholipid tail would form hydrophobic bonds with benzene. The phospholipid head would likely have equal numbers of positively and negatively charged groups that would allow them to form ion-ion interactions helping them pack well and not be bulky. If the heads were still negatively charged they would likely repel each other and be disordered.
Answer:
Dry air.
Explanation:
One definition of dry air is a theoretical sample of air that has no water vapor. Another definition of dry air is air that has a low relative humidity. When the relative humidity drops below about 40%, the air feels dry to the skin.
The skin on the palmar surface of the hands and feet forms ridges, so-called papillary ridges, in patterns that are unique to each individual and which do not change over time. Even identical twins (who share their DNA) do not have identical fingerprints.
Answer: urea disposal
Explanation:
<u>The liver, which is the largest organ in the human body, performs three vital functions of the organism: detoxification, synthesis and storage. </u>
The liver acts as an authentic filter that collects and eliminates numerous toxins, such as ammonia, or toxins that we ingest, such as alcohol (it performs a biotransformation of toxins). Our liver is also responsible for the metabolism of carbohydrates, lipids and proteins, secreting bile, an essential element for the digestion. It also prevents bleeding through a coagulation process. And it is a container of vitamins (A, D, E, K) and glycogen (carbohydrates), while energy is stored in the form of sugar, made available to our organization.
The urea cycle takes place primarily in the liver. Organisms convert ammonia to a less toxic substance, such as urea, via the urea cycle. <u>Then it is released into the bloodstream where it travels to the kidneys and is ultimately excreted in urine. </u>
So, the liver is involved in the production of urea, but the kidney is responsible of its disposal.
