Explanation:
Answer:
Explanation:
Escherichia coli, is a type of bacteria that lives in the intestines. It's also found in the gut of some animals. Most of them are harmless, they aid keeping the digestive tract healthy. Though if contaminated food or fouled water is consumed, some strains can cause diarrhea .
Catalase enzymes, hydroperoxidase I (HPI) and HPII, catalyze the dismutation of hydrogen peroxide to water and oxygen but they play crucial roles in protecting cells against the effects of oxidative stress.
Some examples of pathogenic microorganisms which produces catalase include staph, bacillus, aureus,etc
Test Procedure:
- With the aid of a loop or sterile wooden stick, a small amount of bacterial colony should transferred onto the surface of clean, dry glass slide .
- A drop of 3% Hydrogen peroxide should be placed on to the slide and mixed.
- A positive result is indicated by the rapid evolution of oxygen gas (within 5-10 seconds), which is evident by bubbling, while a negative produces no bubbles or only a few scattered bubbles.
- The used slide should be disposed in the bio hazard glass disposal container.
Los peroxisomas juegan un papel clave en la oxidación de biomoléculas específicas. También contribuyen a la biosíntesis de lípidos de membrana conocidos como plasmalógenos. En las células vegetales, los peroxisomas llevan a cabo funciones adicionales, incluido el reciclaje de carbono del fosfoglicolato durante la fotorrespiración.
Answer:
Favorable adaptation, which is one condition required for natural selection
Explanation:
A population have both beneficial and harmful variations present in its members. The beneficial variations impart survival advantage and makes the individuals better adapted to the surrounding. Several butterflies in the given population have dotted wings. Since presence of dotted wings keeps the predators away, it is a favorable variation that would be favored by natural selection leading to its increase in the population in subsequent generations.
Answer:
Competition among nectar- and pollen-feeding invertebrate pollinators and resource partitioning are affected by introduced Africanized Honey Bees. When Africanized Honey Bees compete with other species of honey bees for flowers, the Africanized bees may displace the other bees from the food sources.
