Why are cnidaria so significant to the animal kingdom?

Biology
1 answer:
nlexa [21]3 years ago
7 0

Answer:

1. They provide home and shelter for millions of species of marine organisms.

2. They play a role as nutrient recyclers and in carbon and nitrogen fixation.

3. They are vital in the marine food chain as they are the main source of essential nutrients.

Explanation:

Cnidarians are extremely ecologically important organisms that play a significant role in the animal kingdom and nature.

For instance, coral reefs, which are built by hundreds to thousands of cnidarians, provide home and shelter for millions of species of marine organisms, from small crustaceans to large fish such as sharks. Furthermore, they play a role as nutrient recyclers and in carbon and nitrogen fixation. In addition, they are vital in the marine food chain as they are the main source of essential nutrients such as nitrogen.

Today, these organisms are threatened due to human activities and anthropogenic climate change, so it is fundamental to develop better strategies to protect and restore them.

Kryger [21]
The correct answer is A, parathyroid gland.

The parathyroid hormone is secreted by the parathyroid gland which <span>inhibits osteoblasts, stimulates osteoclasts,</span> reduces the calcium output by the kidneys and promotes absorption of the calcium by the small intestines. Calcitonin, secreted by the thyroid gland, also works to a similar effect.

How is ATP created in photosynthesis?
uranmaximum [27]

Answer:

The correct answer is option e, that is, a, b and c.  

Explanation:

The phenomenon by which green plants and other species converts light energy into chemical energy is termed as photosynthesis. During photosynthesis, the energy of the light is captivated and is utilized to transform carbon dioxide, water, and minerals into oxygen and energy-rich organic components.  

With the transport of electron through the chloroplast membrane, the energy of the electron causes the diffusion of a hydrogen ion from stroma into the thylakoid lumen, which further leads to a formation of hydrogen ion concentration gradient. This gradient ultimately results in the formation of ATP.

A major theme in biology is the relationship between structure and function. Describe how the structures of chloroplasts and mit
Flura [38]
The structures of chloroplast and mitochondria are similar. Both organelles consist of a smooth outer membrane, folded inner membrane (in chloroplasts called lamellae, in mitochondria called cristae), and fluid intracellular space (in chloroplast called stroma, in mitochondria called matrix). Only these structures allow those organelles to perform their function. The presence of folded inner membranes enables a formation of compartments inside the organelles. Differences in concentrations of hydrogen ions in those compartments are important for photosynthesis in chloroplasts and cellular respiration in mitochondria.
