The right answer is The lac operon would be transcribed constitutively.
An operator is a nucleic acid segment to which a regulatory protein that modulates downstream gene expression is bound. it can either stimulate or inhibit the production of the gene product thus controlled.
If the operator is absent, there will be no more regulation of the operon, so the transcription of the operon will not be regulated, and the synthesis will be continuous and constitutive.
Answer:
The cell would be unable to store food, water and waste D..
The correct answer is<span> C.
Capillaries deliver blood to individual cells; veins generally deliver
oxygen-depleted blood to the heart; arteries generally bring oxygen-rich
blood away from the heart.
That is why the color of the veins is blue, because oxygen depleted blood is much darker than regular blood, so the veins are darker than arteries who have oxygen rich blood.</span>
I believe B. Spores is also involved in asexual reproduction.
Answer:
Reproductive isolation is the very factor that causes the development of what we call "species" according to the biological species concept. The reason cats and dogs are different species is that they can't mate, so we call them "reproductively isolated."
