Yes, an acidic environment will allow more chia seeds to germinate than a neutral environment
Explanation:
Answer:
1. B
2. C
3. A
Explanation:
1. Most of the carbohydrates in the foods you eat are digested and broken down into glucose before entering the bloodstream. Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration.
2. Fats are known as being a long term energy source, and the fat on your body is used a "cushioning" for your bones.
3. To break a protein down into its amino acids you will need enzymes. Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life.
Sunlight. Based on the sunlight you receive you have three zones.
1. Sunlight zone- There is enough sunlight here and photosynthesis can happen. More than 90% of marine animals live in this zone.
2. Twilight zone- A small amount of light is here and no plants grow here. The fish who live here are the ones who have adapted to the little light. Lantern fish is an example.
3. Midnight Zone- 90% of the ocean is in this group. It is entirely dark and the temperature is freezing.
Answer:
a. The original spraying has caused a permanent mutation, giving the insects genetic resistance to the spray.
Explanation:
This is a practical evidences of mutation and variation, as mechanisms of evolution.
The insecticide is the selective pressure. As a results of continuous spray, the parents of the present mosquitoes must have acquired certain characteristics or traits by gene mutation which makes them resistant to the selective pressure (insecticides), and therefore survive the spray in the past.
Therefore when these resistant parents mated, with high reproductive success (leading to large gene pool of these traits,); variation in the genetic composition increases as the resistant gene is passed from generations to generations in the population. Therefore, the population of present day mosquito with genetic resistance to insecticides increases.They are therefore naturally selected, and able to survive as the present day mosquitoes with high resistance to insecticides.
