Answer:

there is no such thing as a free lunch

Explanation:

The maxim "There ain't no such thing as a free lunch" also known as "there is no such thing as a free lunch" (TINSTAAFL), indicates the cost of decision-making and it's aftermath.

In this senerio, a particular genetic strain of Drosophila melanogaster reproduce at an earlier age than do other strains of this species at the expense of its lifecycle as this will cause a shortage of its lifecycle which is a negative aftermath compared to other strains that do not reproduce early.

Manufacturing recombinant dna molecules involves cutting a gene from its normal location, inserting it into a circular piece of
Alex_Xolod [135]
Answer: Plasmid.
A plasmid is a small DNA molecule within a bacteria cell that is separated from the chromosomal DNA and can replicate independently. Through Recombinant DNA, we can insert a gene that we want to see replicated in the plasmid, and when the bacteria multiplies, which it does often, we will obtain a lot of copies of  interest gene.

Ghella [55]
The right answer is: <span>organelle, cell, and tissue

<span>Muscle is a soft tissue, found in animals. Composed of muscle tissue and connective tissue (+ blood vessels + nerves). The muscle cells (a component of the muscle tissue) contain actin and myosin protein filaments that slide on each other, producing a contraction that changes both the length and shape of the cell.
</span></span>The muscle cells, like other cells, consists of a plasma membrane containing a cytoplasm, which is formed of an aqueous solution (Cytosol) in which there are many biomolecules such as proteins and nucleic acids, organized or not in the context of organelles.<span>

Why dont plants photosynthesise in the dark
nignag [31]

Plants respire all the time, whether it is dark or light, because their cells need energy to stay alive. But they can only photosynthesize when they have light.

The oxidation of water occurs during photosynthetic electron transport during the light reactions of photosynthesis. In the absence of a source of light energy (dark reactions have no direct requirement for light energy), oxygen is not produced.
