Answer:
Homeostasis.
Explanation:
A characteristic of living organisms is their ability to maintain internal balance. Therefore, maintaining internal balance inside the body is known as homeostasis.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.
For example, if a person becomes infected with a pathogen such as a virus. The internal stimulus that most likely takes place in order for their body to maintain homeostasis is that their core temperature increases. This is because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).
Answer:
D) A and C
Explanation:
Gram staining is a laboratory technique used for bacterial species. It is used to differentiate between two groups of bacteria based on the components of their cell wall. Gram staining was developed by a scientist called Christian Gram in the year 1884. In the gram stain procedure, the following occurs:
- Due to the thick peptidoglycan component of their cell wall, GRAM POSITIVE bacteria retains the crystal violet due and stain VIOLET.
- On the contrary, due to the thin peptidoglycan component of their cell wall, GRAM NEGATIVE bacteria do not retain the crystal violet dye and hence stain, RED.
Based on this, a bacteria that has been gram stained has been tested for its GRAM REACTION and microscopic morphological characteristics, since it is a microbe.
Answer:
Oil immediately interferes with physical properties of feathers, hair and respiration, making it impossible for many animals to function properly.
Explanation:
For example, birds such as seabirds and bald eagles have to dive or get in the water at least partially in order to catch the fish they eat. Oil makes it impossible for these birds to locate their prey and when they get in contact with oil it makes it impossible for them to fly and be insulated against the cold. Otters and seals also lose insulation against cold water when their hair gets covered with oil and die of hypothermia. Orcas suffer from skin and eye irritation when they get in contact with oil and it may cause problems if it gets swallowed.
