In co dominance, both alleles show. Thus, the filial, F1, generation, will most likely be white with red spots/speckles. See image below.
Answer:
The culture medium must be selective
Explanation:
Selective media are the media that have those ingredients which favor the growth of a particular bacterium and inhibit the growth of unwanted bacteria. So a selective media is used to selectively grow a particular micro-organism.
For example, MacConkey agar is a selective media that is used to isolate gram-negative enteric bacteria based on lactose fermenting ability. It contains ingredients like bile salt and crystal violet which inhibits the growth of gram-positive bacteria therefore it only allows the growth of gram-negative bacteria.
<em>Staphylococcus</em> <em>epidermidis</em> is a gram-positive bacteria and <em>E.coli</em> is gram-negative enteric bacteria so MacConkey agar can be used to select E.coli over <em>Staphylococcus</em> <em>epidermidis</em>. So the correct answer is the culture media must be selective.
Answer:
Some proteins on the surface of a mammalian cell contain carbohydrates. These proteins are synthesized by endoplasmic reticulum _______ and the sugars are added in ___ ER/Golgi__ apparatus.
Explanation:
The protein part of all glycoproteins are synthesized from polyribosomes that then bind to the endoplasmic reticulum (ER). Then the processing of the sugar groups occurs co-and post-translational in the light thereof continuing in the Golgi apparatus for the N-linked glycoproteins.
There are some proteins that are glycosylated inside the ER and then pass to the Golgi (N glycosylation) and others in the Golgi directly (in case of O-glycosylation)
Answer:
B) Mutualism
Explanation:
In mutualism both organisms benefit. The organisms in this example are the fungus and the ants. The ants provide food to the fungus so that it can live. In return the fungus provide food for the ants.
