Answer:
100,000
Explanation:
pH of coffee = 5
pH of solution = 10
Concentration of H+ ions between successive pH values are in multiples of 10
Hence, the pH difference :
pH of solution - pH of coffee
(10 - 5) = 5
Hence, difference in H+ ions will be :
10^5 = 10*10*10*10*10 = 100,000 times
Answer:
Deep zone, surface zone and transition zone.
Explanation:
Open sea zone is the area of the coastal areas above the sea bed and cover the continental shelf where large Marine organism are present and there is enough sunlight algae organism use to photosynthesize and produce food for the Marine organisms by converting carbondioxide and water into carbohydrates.
The zone stretches from the surface , to the middle and depth of 200 m.
The surface zone is the area where light penetrates most , the transition stretches from the surface zone downward, in this zone light penetrates bit not as much as surface zone and in the deep zone, it stretches from the transition zone downward to a depth of 200 meters and don't have enough light penetration compare to surface and transition.
Answer:
Evolution
Explanation:
Evolution is the change in habits, hereditary and physical characteristics of a species over various generations in response to environmental conditions. Evolution lead to adaptation, the nature selection of the fittest and elimination of remaining.
Evolution may produce variety and diversity in response to mutation, genetic drift and other genetic variation. These changes may pass to offspring and may express them more in one group of population.
Evolution also explain the unity among organisms by explaining their shared characteristics. This refers to their common ancestors.
The gastrointestinal wall is composed of four layers or tunics:
- Mucosa
- Submucosa
- Muscularis mucosa
- Serosa
The innermost tunic of the wall is known as the mucosa or mucous membrane layer. The digestive tract's lumen is lined with it. The mucosa comprises epithelium, a layer of lamina propria, a loose layer of connective tissue, and the muscularis mucosa, a thin layer of smooth muscle.
The mucosa is surrounded by a substantial layer of loose connective tissue known as the submucosa. Blood arteries, lymphatic vessels, and neurons are also present in this stratum. The adventitia is a connective tissue that makes up the digestive tract's outermost layer above the diaphragm. It is referred to as serosa below the diaphragm.

<span>An advantage for the angiosperm approach to the formation of nutritive tissue is in energy conservation.</span> <span>The nutritive tissue is formed via double fertilization in Angiosperms. The advantage of double fertilization is that the plant does not invest energy in seed nutritive tissue until after an egg has been fertilized. This means that endosperm (nutritive tissue) starts to develop and store nutrients after it has been fertilized by a sperm cell.</span> Another advantage is that the endosperm nucleus is very active and <span>divides rapidly, so it forms the nutritive tissue very quickly.</span>
