It is believed that insects are so successful because they have a protective shell or exoskeleton, they are small, and they can fly. Their small size and ability to fly permits escape from enemies and dispersal to new environments. ... In addition, insects can produce large numbers of offspring relatively quickly.
Specialization is what each cells personal function is, and differentiation is how one cell is different from another in any way
Answer:
b) The roots grow towards the force of gravity and the stem goes away
Explanation:
The parts of a plant can be divided into shoot and roots. The root of the plant is the part that grows below the ground surface in order to anchor the plant. When a seed germinates, the root part of that seed grows towards GRAVITY i.e exhibits geotropism while the shoot part grows away from gravity i.e. upwards.
Hence, if a seed is planted upside down, it will still grow into an erect mature plant because THE ROOT WILL ALWAYS GROW DOWNWARDS IN RESPONSE TO GRAVITY (positive geotropism) while the stem grows upward away from gravity (negative geotropism)
Answer:
B. Plasmid incompatibility will not allow both plasmids to persist
Explanation:
The two possibilities of why the plasmids are incompatible are:
1) Both plasmids contain the same origin of replicon and compete for the same Rep proteins.
2) Tetracycline: inhibits protein synthesis by binding and inhibiting ribosomal proteins, thus ampicillin target proteins may also be inhibited.
Ampicillin: Causes cell lysis which may lead to inactivation of tetracycline activity since tetracycline needs to diffuse through membrane porin channels prior binding and inhibiting ribosomal proteins.
Natural selection is when the more and better adapted organisms survive to reproduce and the weaker and less adapt die.
