Which hypothesis helps to explain why all organisms share the same genetic code?
KonstantinChe [14]

Answer:

There are two possible answers: Deep-sea vents provided the energy needed for the first organic compounds to form OR self-replicating RNA molecules passed on genetic information.

Explanation:

The reason for the first answer is due to the hypothesis that indicates that life (organic molecules) arose from inorganic molecules synthesized from the amino acids in those energy vents. This is called the metabolism first hypothesis. The Miller-Urey Experiment provided evidence that organisms could rise from inorganic molecules (they simulated under the conditions you would see on early Earth). The second hypothesis is the RNA World hypothesis (second answer) which suggests that the formation of RNA that could replicate (possible due to mutation or evolution), led to life that could preserve its genetic integrity through replication (greater stability to the organism) and create lipid bi-layer membranes/other organelles. Some scientists support the Metabolism First Hypothesis, while others are skeptical (this goes for the RNA World Hypothesis as well). However, the RNA World Hypothesis is for more reasonable in the fact that its main point is the fact that RNA molecules were able to replicate and maintain genetic stability despite early Earth conditions. Although either hypothesis could explain why all organisms share the same genetic code, the RNA World Hypothesis better explains the universality of DNA/RNA of genes that we see today.

Are you likley to find zooplanton in the aphotic, benthric zone of a ocean
likoan [24]
No. Zooplankton feed on phytoplankton. Phytoplankton cannot photosynthesize in the dark. (The Benthric Zone is the lowest level of the ocean/a body of water, no sunlight can really reach there.)

after the brain receives information from the body's sensory receptors, what is the next step in responding to this information?
Bumek [7]

The sensory receptors refer to the portions of the nervous system, which sense variations in the external or internal surroundings. The sensory input can be in various forms, comprising taste, pressure, light, sound, pH of blood, or levels of hormones, which are transformed into a signal and are transmitted to the brain or spinal cord.  

In the sensory centers of the brain, the barrage of information is integrated and a response is produced. The response, that is, a motor output refers to a signal conducted towards organs via motor neurons, which then transforms the signal into some kind of action, like changes in heart rate, movement, discharge of hormones, and others.

Phospholipids, steroids and glycolipids are amphipathic and can form membranes made of lipid bilayers. On the other hand, trigly
Svetlanka [38]

Answer:

The cell membrane of the living organism is made of the lipid bilayer and proteins. The most common lipid present in the plasma membrane is the phospholipids.

Phospholipids has both the hydrophobic tail and hydrophilic head. The hydrophobic region interacts with each other. The lipid layer of phopholipids gets in association with the hydrocarbon chain of triglycerides. Their hydrophilic part dissolve in each other.
