Answer:
The statements are correct.
Explanation:
Cell culture is a technique widely used in molecular biology where cell lines are grown in controlled conditions, thus allowing to make experiments and to test compounds that may result useful to treat diverse diseases, including cancer.
Immortalized cell lines are characterized for their ability to proliferate indefinitely which are derived from oncogenic tissues. In cancer research, these lines are used as models to test different drugs and to study cellular mechanisms associated with cancer progression including, among others, proliferation, invasiveness, vascularization, etc. In addition, the mechanisms associated with the death of cancer cells such as, for instance, apoptosis, may also be studied by using immortalized lines.

Answer:
sweepstake route
Explanation:
From the view of the horses, the ocean barrier would be seen as a <u>sweepstake route</u>.
<em>By definition, the sweepstake route refers to a rather difficult or dangerous path through which animals can move from one place to another. No animal would take this path ordinarily except by pure chance or when events leave no other option.</em>
In the illustration, no horse would engage in an adventure of swimming across the ocean to North America until the European settlers decided to ferry them across. Hence, to the horses, the ocean barrier represents a sweepstake route.
ok well first it does two things it changes its shape (denature) and it slows down so its either b or d
Enveloped viral membranes are generally (C)lipid bilayers with associated virus-specific (C)glycoproteins.
Viruses are intracellular parasites that hijack the cellular machinery for their own replication. Therefore, an essential step in the viral life cycle is the transfer of the viral genome into cells. Enveloped viruses (viruses with a lipid envelope) use a two-step process to release their genetic material into the cell.
It first binds to specific surface receptors on target cell membranes and then fuses with these. Viruses and cell membranes. This last step can occur at the cell surface or after internalization of the virus particle by endocytosis or another pathway (such as micropinocytosis).
Strikingly, the virus-cell-membrane fusion process proceeds along essentially the same intermediate steps as other membrane fusions that occur, for example, in vesicle fusion at neural synapses or cell-cell fusion in yeast mating. Fusogens, special viral proteins, facilitate the fusion of viruses and cell membranes.
