Natural air pollution comes from those known as wild fires, and volcanic smoke. If you wonder why well it's because of the smoke it contains and produces. Smoke is one of our biggest air pollution and it contaminates our atmosphere.
I'll provide pictures of natural air pollution..
Note:
These pictures don't belong to me.
I hope this helps.
Answer:
a. The embryo would suffocate or dehydrate.
Explanation:
Chorion is one of the four extraembryonic membranes that cover the embryo inside the egg. Chorion develops into the part of placenta-derived from the fetus.
Trophoblast develops into chorion during pre-embryonic development. Once formed, the chorion develops villi that are required for the exchange of material, specifically the respiratory gases, between the mother and fetus.
If an egg had nonfunctional chorion, the developing embryo will not get the supply of gases. In the absence of gas exchange between mother and embryo, the embryo will die of suffocation.
Chorion is also involved in the development of the placenta which in turn is the organ of the exchange of nutrients and gases and removal of toxic material.
Nonfunctional chorion would not support the placenta formation and the embryo will not get the supply of nutrients and water.
Light rays passes through the pupil in the eye and activates the neurons in the retina. The light wavers that are from the reflection of the object are transformed into neural impulses or transduction then action potentials are released when electrical charges are sent through the neurons. Excitatory neurotransmitters are supplied when action potential goes to the axon terminal and the thalamus routes the neural message from the retina elsewhere in the brain. Feature detectors organize the visual projection of the object.
The best answer for this question would be:
environmental conditions affect the pollination of plants.
Because it depicts the starting information or theory that the researcher is stating. His theory is that the conditions of the plant will affect the plant, and therefore experiments on the procedure to prove his theory.<span> </span>
