Answer:
15%
Together, adenine and thymine compose 70% of the segment. This means that 30% of the section is composed of guanine-cytosine pairs. Since these two bases will be equal in quantity, 15% of the DNA section will be cytosine bases.
Answer:
False
Explanation:
An aquifer is an underground layer of water-bearing permeable rock or rock fractures or. The system shows two aquifers with one aquitard. Some abundant small openings store a large quantity of water. Groundwater may exist in underground rivers or underground cave systems where water flows freely underground. If the impermeable area overlies the aquifer, pressure could cause it to become a confined aquifer.
Anticipating that one is about to eat can trigger the cephalic phase of digestion.
The cephalic phase of digestion is the stage during which the stomach responds to the mere sight, smell, taste as well as thought of food. Approximately 20% of total acid secretion takes place before food reaches the stomach.
During this phase of digestion, gastric acid and pepsinogen secretion is activated by the thought, sight or smell of food and also when food is inside the mouth.
The cephalic phase of gastric secretion is moderated completely through the parasympathetic nervous system. A variety of sensory stimuli including the sight, smell, and taste of food induces acid secretion in the stomach.

Answer:
100% of the water is part of the hydrological cycle.
Explanation:
The hydrological cycle is a cyclic process that occurs mainly in the biosphere; this hydrological cycle is in constant movement in the repetition of its cycle; it has different stages, among them the evaporation, condensation, precipitation, infiltration among others.
In the hydrological cycle, 100% of water enters, which is obtained mostly from the oceans; another percentage is extracted from glacier ice and groundwater, also acquires a small percentage of water from the atmosphere and freshwater. And the time of permanence of the water in the hydrological cycle depends on its quantity, so will be the days that it will remain.
