The coyote (canis latrans) is found across North America which makes it a specialist species. Its false
Answer:
The correct answer will be option-A.
Explanation:
Lac operon is a set of genes arranged sequentially for lactose metabolism in E.coli. The lac operon gets activated in the presence of lactose as the lac operon consists of three enzyme coding genes called lacZ which codes for the β-galactosidase enzyme, lacY which codes for lactose permease, lacA which codes for acetyltransferase along with a regulatory gene called lacI which codes for repressor proteins.
The repressor proteins bind to the operator and control the transcription. When it binds to operator its huts off the transcription. If a mutation occurs in the laci gene then the protein will lose the machinery which will turn off the activity of enzymes and will lead to the constitutive expression of the genes irrespective of the inducer present or not.
Thus, option-A is the correct answer.
Answer:
D) Energy is required in order to maintain homeostasis--without a constant, organized internal state, the cell will die.
Explanation:
Homeostasis is the condition of relative stability that the body needs to perform its functions properly for the body's balance.
Despite changes that may occur in the body, internally or externally, homeostasis is the constancy of the internal environment (interstitial fluid). Keeping at an appropriate temperature (37º C) ensuring that the necessary changes to the body occur; and thus the cells of the body develop.
Because of homeostasis, cells need a constant supply of energy. That's because energy is needed to maintain homeostasis - without a constant, organized internal state, the cell will die.
They do not require water because the stamen releases male gametophytes that are carried by the wind to the egg in the carpel.
