Answer:
two sets of magnifying lenses
Explanation:
This is because a compound microscope is a high magnifying microscope that have multiple lenses or two magnifying lenses which help to see or observe or magnify image very well compare to single lense. It is a high power microscope and it has high level of magnification because of the
two magnifying lenses. It produces two dimensional image. The eyepieces and the objective lenses give a very high magnification, a condenser that is below the stage focus the light into the specimen to be viewed.
Answer: Base: a substance that produces hydroxide ions when dissolved in water. Bases have a pH greater than 7. A base is any substance that dissolves in water and produces hydroxide ions, Hydrochloric acid is a STRONG acid because it completely dissolves into H+ and Cl- ions in water.
Explanation:
Answer:
Examples:
- Short-term adaptation: feedback inhibition
- Long-term adaptation: regulation of gene expression
Explanation:
Feedback inhibition is a mechanism where the product of a chemical reaction is utilized to modulate its own subsequent synthesis. In bacteria, feedback inhibition allows regulating different metabolic pathways in response to environmental conditions by modulating enzyme activity through enzyme reaction products. Moreover, bacteria may also respond to environmental inputs by long-term changes in gene expression. For example, bacteria contain transcription factors activated during stress, which are able to activate the transcription of particular genes into messenger RNAs (mRNAs) that would subsequently be used to generate particular enzymes by the process of translation. These transcription factors may bind to specific DNA motifs in order to promote transcriptional activity, thereby regulating the production of the corresponding enzyme.
Answer:
In many species, females choose the male they will mate with. For their part, males try to be chosen as mates. They show females that they would be a better mate than the other males. To be chosen as a mate, males may perform courtship behaviors. These are special behaviors that help attract a mate. Male courtship behaviors get the attention of females and show off a male’s traits. These behaviors are often observed as direct competition between males. Different species have different courtship behaviors.
