- helps protect internal organs and fragile body tissues eg. : the cranium protects your brain and eyes and the ribs protect your heart and lungs.
Answer;
High-energy electrons pump hydrogen ions against the concentration gradient.
Explanation;
-The electron transport chain sets up a proton concentration gradient across the inner mitochondrial membrane, with more protons outside the membrane.
-As a result of this gradient, the protons are waiting to get across the membrane. This happens through the transmembrane protein ATP synthase, which uses the energy moving protons through its pore to add a phosphate to ADP, thus producing ATP.
Answer: Below
Explanation:
Alligators play an important role in maintaining ecosystem balance. Sitting at the top of the food chain, alligators are top predators and help keep other animal populations in balance. By digging holes and leaving trails throughout marshes, they create habitats for fish and marine invertebrates
A. assemble amino acids
Mycorrhizae are fungal colonies that are in a mutualistic relationship with plants. These fungi help the plant absorb more nutrients and water from the soil, while the plant provides the fungus with carbohydrates that it generates through the process of photosynthesis. Mycorrhizae do not carry out the assimilation of amino acids, this is a process carried out the plant by itself.
The correct answer is emphysema.
Emphysema is the enlargement of air sacs in the lungs.
It is a long-term, progressive disease of the lungs that primarily causes shortness of breath. People who have emphysema, their air sacs in the lungs (alveoli) is damaged. Over a period of time, the inner walls of the air sacs weaken and rupture creating larger spaces instead of many small ones. Normally, the lung tissue holds these small airways called bronchioles, open, allowing air to leave the lungs on exhalation. However, when the lung tissue is damaged like in the case of emphysema, these airway collapse, making it difficult for the lungs to empty and the air (gases) becomes trapped in the alveoli thus causing impaired gas exchange.
