Enzymes are a type of protein that aid in which of the following processes?
- cellular signaling and regulation
- transport across the cell membrane
- the breakdown of food molecules
- all of these
I think you forgot the answer choices. Is this your question?
If so, it is <u>D) all of these. </u>Enzymes aid in all kinds of microbiological processes, including cellular signalization, regulation and transportation - in addition to the breakdown of nutrients.
We must first define these three prominent definitions of species. Biological species concept means that organisms resemble each other because of genes being passed from parent to offspring. Phylogenetic species concept means that organisms resemble each other because they evolved from a common ancestor. Lastly, morphological species concept characterizes species on the structure of their body parts rather than genetic or phylogeny.
In this case, (1) biological species concept is not applicable for extinct species, (2) phylogenetic species concept is based on evolutionary history, (3) morphological species concept relies on similarities in structure, (4) Morphological and phylogenetic species concept accommodates asexual reproduction, and lastly (5) all species concepts are used by scientists in classification.
Answer:
true
Explanation:
Green plants have the ability to make their own food. They do this with a process called photosynthesis, which uses chlorophyll. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide and water into glucose.
The correct answer is: C) exposing the bacteria to an antibiotic that kills cells lacking the resistant plasmid
The plasmids are inserted into bacteria by the process called transformation. Bacteria need to be treated, for example with heat, in order to take up foreign DNA (recombinant plasmid). A inserted recombinant plasmid contains an antibiotic resistance gene, which allows bacteria to survive in the presence of a specific antibiotic. So, this fact is used for the selection of bacteria that are and are not transformed.
I'd say the answer is C but I'm not 100% sure. If not C then maybe B
