hi i need a definition of adaptation, camouflage, habitat, hibernation, migration, mimicry, niche, predator, prey, reproduction,
gladu [14]
Answer:
species is a group of organisms of common ancestry able to reproduce only among. reproduction is Formation of new cells or a new individual. adaptation is A changing to fit new conditions. niche is ecology) the status of an organism within its environment and community (affecting its survival as a species). camouflage is camouflage. mimicry is Gaining protection by looking and acting like a different species. migration is Form of relocation diffusion involving permanent move to a new location. hibernation is A state of extremely low metabolism and respiration, accompanied by lower-than-normal body temperatures. predator is An animal that hunts other animals for food. prey is Animal hunted or caught for food. habitat is Place where an organism lives. organism is any living thing made up of one or more cells. invasive species is plants and animals that have migrated to places where they are not native. last non native species is not from an area, usually harmful.
Explanation:
The answer is B. It is B because in if convection currents cooled down then the earth would die.
Answer:
B. the presence of cyclic AMP and lactose
Explanation:
Maximal transcription of the lac operon requires the presence of cyclic AMP and lactose. Cyclic AMP/CRP complex attached to a specific sequence in the lac control region. This region is known as the "CAP" site. Mutations that occurs in the CAP site prevent cyclic AMP-CRP binding which also prevent high levels of expression of the lac operon. The lac repressor and catabolite activator protein (CAP) are the two regulators that is responsible for turn on and off the operon in response to lactose and glucose levels.
Answer:
Heterotrophs
Explanation:
Heterotrophs are organisms that are not able to form their own source of energy and are dependent on others to gain energy. Most of the algae are autotrophs which uses light energy to make organic energy source.
Some algae are heterotrophs that do not require sunlight and pigments as they do not make their food on their own and utilize sugars manufactured by other plants and algae.
They are also called colorless algae as they do not possess pigments. These heterotrophic algae are consumers, not producers. Therefore the correct answer is heterotrophs.
