As most microbes reproduce asexually, "species" are defined by differences in their DNA sequences. when the genome of soil microbe a is analyzed, long stretches of genes from multiple species of other soil microbial species are discovered. This indicates that the microbes present in the soil underwent transformation and transfection. Transformation, shown in the image, is the process of the prokaryotic nucleus taking up the foreign DNA from other microbes present in the environment. Tranfection is like transformation but for the eukaryotic cells.
The bear, even though it is a very heavy and bulky animal, it can run pretty fast, and can easily outrun a human, but this is while running straight or when making gradual turns. The situation changes if the human starts running in a zigzag pattern. The human is much lighter, quick acceleration, long thin legs, and is much more agile, which will all be its advantage because in this kind of a chase the agility and acceleration are crucial. The bear on the other hand, will find it very difficult because its weight will disable it to make quick turns, it has a slow acceleration, and is not agile. So a human with a solid amount of stamina with using this tactic has a pretty good chances of escaping a charging bear.

Answer:
Dexamethasone drug in an individual lowers the level of plasma cortisol by lowering the release of Adrenocorticotropic hormone from the anterior lobe of pituitary gland.But in case of people suffering from Cushing syndrome dose of dexamethasone does not lowers the plasma cortisol level.
Explanation:
Dexamethasone is a synthetic Glucocorticoid.As a result it"s functions will be analogous to that of Glucocorticoid.Dexamethasone generally stimulate the rate of Gluconeogenesis thus increasing the production of glucose.As a result the plasma glucose level is elevated.
B. A non-contact force that is generated from moving charges.
Explanation:
- Magnetic force is a non -contact force
- It is an attractive force or repulsive force.
- It acts between two charged particles by virtue of their motion.
- Materials that exhibit magnetic force of attraction or repulsion are called magnets.
- Uncharged material that are attracted by magnets are called magnetic material.
