Answer:
Environmental factors can alter gene expression, cell signalling and cell differentiation.
Explanation:
- Environmental factors can change, stop or disrupt the process of cell signalling and gene expression in organisms.
- The environmental factors are drugs, chemicals, temperature, etc.
- With the effect of environmental factors, the organism will try to adapt to the environment by changing the internal process.
- In case of adaptation, some organism may survive to the changing environment but there is a risk of exhibiting defects and in some case, the result can be death.
The vasa vasorum is a network of small blood vessels that supply the walls of large blood vessels, such as the aorta and vena cava.
Koch's postulates serve to give criteria that gives causality between a microbe and a disease.
A common edible mushroom is Agaricus bisropis. Penicillium hypogeum is a common antibiotic.
<h3>
What are organisms?</h3>
There are many organisms in the world such as fungi, bacteria, and many other organisms.
A common edible mushroom is Agaricus bisropis. It is a common basidiomycete. It is a heterotroph. Penicillium chysogenum is a commonly occurring mold and is used as an antibiotic.
Saccharomyces cerevisiae is commonly used as baker's yeast. It is used in making bread, and cakes. Elm tree parasite is Ceratocystis ulmi
Therefore, A common edible mushroom is Agaricus bisropis. Penicillium hypogeum is a common antibiotic.

Cyclins
are the chemicals that regulate the cell cycle. Cyclins work by regulating the timing
of the cell cycle in eukaryotic cell. Cyclins activates cyclin dependent
kinases (CDKs) (an enzyme that works by adding <span>negatively charged phosphate groups to other
molecules in a process called phosphorylation) by binding to it to form a cyclin-Cdk
complex. This complex then functions by acting as a signal to the cell to move
to the next cell cycle phase. At the end of the event, the cyclin is degraded, Cdk
is deactivated, therefore signaling exit from a specific phase.</span>
