The answer is b.nucleus. Because nucleus contains DNA/genes which contain the information(genetic information) for cell functioning
Carnivores' biological traits aid in their ability to hunt. Wolves and other carnivorous mammals have powerful jaws and large, sharp teeth that enable them to seize and tear apart their food. On the other hand, plant-eating animals typically have large molars that aid in the grinding of leaves and grasses.
Carnivores are the largest animals in the world. The blue whale can grow to be 30 meters (100 feet) long and up to 180 tonnes in weight (200 tons). It eats by gulping down large amounts of water and filtering out microscopic krill organisms, which resemble shrimp. About 40 million of the tiny animals, or 3.6 metric tonnes (4 tonnes), can be consumed daily by blue whales.
The polar bear, which mostly consumes seals, is the largest terrestrial carnivore. Sharp claws are a hunting tool for cats like lions, cougars, and other species. Birds with talons, often known as claws, use them to hunt, including hawks and owls. The curved beaks of many carnivorous birds, known as raptors, are used to break apart their prey.

Answer:
If the petri plates are kept open for the longer duration of time then there are chances of cross contamination.
The contamination can be defined as growth of undesired microbes in the petri dishes or tubes which is no longer useful for the experiment.
The tube if kept open will develop the growth of contaminants in it. It can be cross contamination as well.
To avoid contamination the tubes and dishes should not be kept open for a longer duration of time.
Answer:
Integrated pest management (IPM), also known as integrated pest control (IPC) is a broad-based approach that integrates practices for economic control of pests. IPM aims to suppress pest populations below the economic injury level (EIL).
