The two membranes pull apart a little and create a small pocket or sack of air. As the developing bird grows, it breathes in oxygen from the air sack and exhales carbon dioxide. Several thousand microscopic pores all over the surface of the egg allow the CO2 to escape and fresh air to get in.

Describe what you think is happening during photosynthesis.
boyakko [2]

Answer:

During photosynthesis, plants take in carbon dioxide (CO 2) and water (H 2 O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Explanation:

The energy for photosynthesis comes from light. Light energy is converted to chemical energy by chlorophyll. There are two sets of reactions, light dependent and light independent. The process mostly takes place in the chloroplasts of plant leaf mesophyll cells. Photosynthesis is the process where a plants uses the sun’s energy to turn light into chlorophyll. Plants produce oxygen during this process and utilize carbon dioxide. Photosynthesis is the single most important chemical process on the earth. Almost all plants needs the sun in order to survive Photosynthesis is the most important chemical process on earth – it provides food and energy for all living creatures who eat the plants that rely on this process to produce their food (glucose). · More than half (70%) of the world’s oxygen is produced by phytoplankton photosynthesis in the world’s oceans.

The pronunciation of the anatomic structure that conducts impulses to and from the brain and initiates reflex action to sensory
sergejj [24]

The pronunciation of the anatomic structure that conducts impulses to and from the brain and initiates reflex action to sensory information is the spinal cord.

  • The spinal cord is a lengthy band of tissue that resembles a tube. It ties your brain and lowers it back together.
  • Your spinal cord relays nerve messages back and forth from your brain to your body. You can experience feelings and move your body thanks to these nerve transmissions.
  • The protection of the spinal cord, nerve roots, and many internal organs are the spine's three primary tasks. To keep your body upright, give it balance and structural support.
  • Enable fluid movement. The spinal cord is surrounded by cerebrospinal fluid (CSF), which is additionally protected by three layers known as the meninges (dura, arachnoid, and pia mater). The spinal column, which consists of 33 bones known as vertebrae, houses the spinal cord.
