Answer:
Amino acids.
Explanation:
Miller -Urey experiment was performed by creating the primitive earth condition in the laboratory. The main aim of this test was to determine the chemical origin of the life.
The electrodes was used to create the spark conditions and different gases like water, methane, ammonia, and hydrogen. The product was obtained after some days of the reaction. The amino acids like glutamic acid, glycine, α-alanine and β-alanine was obtained from the product of this experiment.
Thus, the correct answer is option (1).
The answers are the following:
- Hypothesis: caffeine affects the rate of mitosis in frog eggs
- Null hypothesis: caffeine has no effects on the rate of mitosis in frog eggs
- Independent variable: time
- Dependent variables: rate of mitosis in frog eggs, amount of caffeine used in each treatment, etc
- Control group: rate of mitosis in frog eggs no treated with caffeine
Answer:
Deforestation has an effect on the Carbon Cycle also known as the Greenhouse gas effect and global warming. Trees and forest balance the amount of Carbon in the atmosphere through the process of photosynthesis in which plants make their own food with carbon dioxide. ... This excess heat warms the earth.
It is acidic and it contains many H+ (Hydrogen ions)
