Oxygen-poor blood goes into the lungs and through the lung capillaries after leaving the heart. It does so to be oxygenated by the lungs. The oxygen in the lungs comes from the air we breath. Once the blood is oxygenated, it goes back into the heart, to be pumped back into our bodies for distribution.

How do plants grow helppp

cricket20 [7]

Answer:

During photosynthesis, plants take the water from the soil, and the carbon dioxide from the air, and they make sugars out of it. When plants have the right balance of water, air, sunlight and nutrients, their cells grow and divide, and the whole plant gets bigger and bigger. And that's how plants grow.

The first step in using amino acids as fuel is to __________ them.

Mice21 [21]

If i'm not mistaken amino acids can be used in our body to fuel a process in which cell replication occurs and DNA is made. So to use amino acids as fuel you would have to make sure everything is in correct order and lines up correctly from the time it's released from the nucleus to a ribosome.

Are insects intermediate host or definitive host? Are there any symptoms of gongylonemiasis? If the insects are the definitive h

Lemur [1.5K]

Answer:

They are intermediate hosts.

Explanation:

Disease-transmitting insects are called vectors.

The life cycle of disease-causing pathogens is closely linked to the biology of the insect that carries it.

The symptoms of gongylonemiasis include hemorrhagic inflammation at the site the pathogen invades, followed by granulomatous tissue development that produces nodules in the invaded organ.

Some diseases transmitted by insects occur in both humans and other mammals because our differences in anatomy and physiology are not very different.

It is unlikely that clinical symptoms will occur in humans if the insect were the definitive host, because our biology is quite different from their biology, and the pathogen would be adapted to fulfill its entire life cycle in their body.
