D) lack the ability to reproduce without as stated in cell theory
<span>Schleiden and Theodor Schwann (1810-1882)were the first to recognize that all plants and animals are composed of cells. [ In 1839, they defined their "cell theory" in which they also stated that nuclei and cell membranes are common to all cells and recognized the presence of unicellular (single-celled) and multicellular (many-celled) organisms.

Hope this helps for number 2 not worried about points
A chemical reaction can be described by discussing the chemical substances at all steps. It is more efficient to use a chemical equation than words, and there are agreed-upon conventions to summarize the reaction, the substances that take part in it, the products, and the amounts
Answer:
After boiling the cell would have lost its water (dehydrated).It appears like a deflated balloon. Now it needs water to regain its original form or swell. When it is placed in hypotonic med. the water from the medium enters into the cell .Hence it regains its size. The process occurred here is called “endosmosis”. This is due to a concentration gradient of water between the medium and the cell. Excess water enters into the cell which has less water or say no water at all.
Explanation:
Bacteria that have
taken up the plasmid with antibiotic resistance
gene will grow in a medium laced with the particular antibiotic of interest. More
so, the bacteria that take up plasmid with the lac Z gene, when grown in a medium of lactose only, will propagate. These experiments
are used with selective media that only allows the bacteria with a particular characteristic
to grow.
