Water exists as a solid at or below 0 degree Celsius.
At 0 degree Celsius, water can go through a phase change, either freezing or melting, depending whether energy is given or taken away. If the temperature is below 0, water should exist as solid as the temperature is lower than its melting point. If the temperature is right at 0 degree, the water can partially be solid and liquid at the same time, during phase change.
Therefore, water exists as solid at or below 0 degree Celsius.
The answer is nucleus acids
Answer:
They are training animals in a maze and recording physiological changes in their brains, Stimulating a brain structure and recording subsequent changes in movement, Introducing two adults that are potentially attracted to each other, and then measuring their sex hormone levels, Measuring the brain volumes and intelligences of people in a group, Observing enlarged cerebral ventricles in the brains of many people with schizophrenia, Severing the connections between visual regions and the rest of the brain in animals, and observing the animals’ failure to recognize an object, and Studying the relationship between a sex hormone treatment and strength of an animal’s mating behavior.
Explanation:
Answer:
Lysosomes.
Explanation:
HEXA (Hexosaminidase A) is the functional enzyme and encoded by the HEXA gene. The main function of this enzyme is the hydroxylation of the gangliosides.
The mutation in this gene leads to the lysosomal storage disease. The GM2 starts accumulating in the lysosomes and causes Tay Sach's disease. This is a genetic disorder that leads to the breakdown of the cells of the spinal cord and the brain.
Thus, the answer is lysosomes.
