We can confirm that if we used a minimal medium first and attempted to transfer from that to a complete medium second, certain types of bacteria would not be able to survive the first medium.
What bacteria would be affected?This has to do with many kinds of bacteria, but particularly auxotrophs. These are bacteria who have trouble producing the substances they need to survive, so in an incomplete medium, these bacteria would not have a high chance to survive until moved to the complete medium.
Therefore, we can confirm that if we used a minimal medium first and attempted to transfer from that to a complete medium second, certain types of bacteria would not be able to survive the first medium.

which fossil record would likely show more diversity in-living organisms of marine organisms?
Answer:
The correct answer is desert-dwelling species.
Explanation:
Any preserved remains, trace or impression of anything, which was once living in the past is termed as a fossil. The examples of fossils comprise stone imprints of microbes or animals, bones, exoskeletons, shells, coral, remnants of DNA, the substances getting preserved in amber, and others.
For the formation of fossils, the most essential condition is decomposition that takes place gradually, that is, at a slow pace. Thus, places like wet marshy areas will be the locations where the maximum of the fossils can be found as such places provide optimum conditions for slow mineralization and decomposition of bones.

why is it easy for a virus to mutate?
Answer:
Viruses mutate very quickly The major reason that viruses evolve faster than say, mosquitoes or snakes or bed bugs, is because they multiply faster than other organisms. And that means every new individual is an opportunity for new mutations as they make a copy of their genetic material. Many of those mutations have no noticeable effect.

What is the primary function of dermal tissue?
water storage
protection
nutrient transport
support
Answer:
Primary dermal tissues, called epidermis, make up the outer layer of all plant organs (e.g., stems, roots, leaves, flowers). They help deter excess water loss and invasion by insects and microorganisms. The vascular tissues are of two kinds: water-transporting xylem and food-transporting phloem.
For a quick simple answer, it's nutrient transport.
describing the action potential and its phases
An action potential is caused by either threshold or suprathreshold stimuli upon a neuron. It consists of four phases; hypopolarization, depolarization, overshoot, and repolarization. An action potential propagates along the cell membrane of an axon until it reaches the terminal button.

Answer:
I think that GMOs don't provide a threat to humans. According to Kurzguzat - In a Nutshell, the "pests" that are engineered into the plant aren't actually harmful to humans. This is called a BT protein and doesn't hurt humans. There were eggplants in Bangladesh that kept getting destroyed by pests, and the genetically modified plant stopped the farmers from using massive amounts of pesticides on the plants.

How do the structures of the cardiac muscle and skin tissue support their functions within the body? (Hint: Think abou
Answer:
See below
Explanation:
The structure of the cell is very much linked with the functions of the cell. The cardiac muscle is made of the myocardium which serves the body by providing the blood, nutrients and oxygen. The cardiac muscles appear striped when seen under a microscope.
The skin consists of the tissues and cells which are close enough to create a boundary that does not allow the entry of materials and pathogens inside the body.
Hence, the function and the morphology of the cells are somewhere related to each other.
