In animals, carbon dioxide waste is exchanged for
LUCKY_DIMON [66]

Answer:

oxygen

Explanation:

  • Through the process of respiration , in lung the carbon dioxide from the blood is exchanged with oxygen.
  • The smallest dunctional unit if the lung is the alveoli
  • At this level the gases are exchange through the capillaries present close to the alveoli.
  • The concentration gradient ,meaning the greater amount of oxygen present in the lungs and greater amount of carbon dioxide in the blood creates a gradient that allow the movment of oxygen into the blood and carbon dioxide in the alveoli through the membrane .
  • Partial pressure created allows the easy movement .The carbon dioxide get into the trachea and expelled through nose and mouth.

During the life cycle of a seedless plant, a sporophyte releases
Agata [3.3K]

Answer:

Seedless vascular plants are plants that contain vascular tissue, but do not produce flowers or seeds. In seedless vascular plants, such as ferns and horsetails, the plants reproduce using haploid, unicellular spores instead of seeds. The spores are very lightweight (unlike many seeds), which allows for their easy dispersion in the wind and for the plants to spread to new habitats. Although seedless vascular plants have evolved to spread to all types of habitats, they still depend on water during fertilization, as the sperm must swim on a layer of moisture to reach the egg. This step in reproduction explains why ferns and their relatives are more abundant in damp environments, including marshes and rainforests. The life cycle of seedless vascular plants is an alternation of generations, where the diploid sporophyte alternates with the haploid gametophyte phase. The diploid sporophyte is the dominant phase of the life cycle, while the gametophyte is an inconspicuous, but still-independent, organism. Throughout plant evolution, there is a clear reversal of roles in the dominant phase of the life cycle

ICE Princess25 [194]

Answer:

All biological enzymes function best at particular pH values (most require pH 6 to 7) in the human stomach, the pH of 2-3 provides the environment required for the proper functioning of the digestive enzymes found there and this is the perfect condition for preservation of food and digestion of food.

Explanation:

The adding of basic material decrease acidity that happens due to the lower pH of the stomach. The very common basic material which is used to neutralize the acidity of stomach milk of magnesia.

The lower pH of the stomach cause acidity which is injurious to the health and also the mucous lining of the stomach. To balance is acidity milk of magnesia is required.
