Answer:the fitness of an organism is the ability to survive and reproduce
Explanation:
Your respiratory system prevents harmful substances from entering the lungs by using: .Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean
Answer:
The daughter cells are genetically identical because mitosis is a process that ensures the equal distribution of the replicated genetic material between these cells
Explanation:
During mitosis, the DNA is duplicated during the interphase (S-phase). Subsequently, the replicated chromosomes are arranged in the center of the parent cell (metaphase) to be finally separated and equally distributed between the daughter cells.
Answer:
Osmosis
Explanation:
As mentioned in the question,Pacific sea horse is an organism that face the constant challenge of losing water to their saltier environment. So if the environment is saltier it means that water will be moved from the Pacific horse' body cells into the environment to balance the concentration of salts. This process will happen when water molecules will move down the concentration gradient through selectively permeable membrane's of horse's body. This causes the loss of water from the body of horse and maintaining the salt levels of outside environment. This is called the process of Osmosis.
Here water move from an hypotonic environment (with less salts) into a hypertonic environment (with more salts).
