Answer: The brain stem, at the bottom of the brain, connects the cerebrum with the spinal cord. It includes the midbrain, the pons, and the medulla. It controls fundamental body functions such as breathing, eye movements, blood pressure, heartbeat, and swallowing.
Explanation:
Answer:
Non-vascular plants are plants without xylem and phloem. The parts of the plant that transport nutrients/sugars(phloem) and water/ minerals(xylem)
Seedless vascular plants have xylem and phloem, but only make leaves, not flowers or seed
Explanation:
Answer: When Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Then ions produced are oppositely charged and are attracted to one another due to electrostatic forces.
Explanation:
Air pollution has become an extremely serious problem. Air pollutants affect both plants and animals. Under polluted conditions, plants develop different physiological, morphological and anatomical changes. Pollutants cause damage to cuticular waxes by which then they enter the leaves through stomata. This further leads to injury to plants which can be either acute or chronic. Changes in stomata due to air pollutants which seem to be small can be of great consequence with respect to survival of the plant during stress. These effects can further lead to disturbing the water balance of leaf or whole plant. Respiration also gets affected because of the exposure of plants to air pollutants. The present paper deals with the effect of air pollutants on stomata as well as on respiration leading to affect gaseous exchange.
Answer:
Enzyme structure begins to break down
Explanation:
The enzyme will begin to denature as the temperature in the body rises. Denaturing is when the physical structure of the enzyme loses its shape and prevents the lock and key of enzymes and substrates to occur.
