Answer and explanation;
-A diverse community would be more resistant to disease, predation, and invasion because it would be a bigger diversity of genes, which means that the chance of disease would be more likely to spread in a different area than in a diverse population.
-Diversity is expected to increase the resilience of ecosystems. A diverse community would be more resistant to disease because of simple biology. The more sources for possible resistance the better the heterogeneous pool will be at resisting disease.
-High diversity strengthens a community and prevents invasion of the introduced predator. After a gradual loss of native species, the introduced predator can escape control and the system collapses into a contrasting, invaded, low-diversity state.
It would be A. Commensalism because only the plant is being benefitted in this relationship, whilst there is no harm nor benefits done to the fungus.
Answer:
A = Activator
B = Effector
Explanation:
An activator is a protein which typically binds to a short (50–1500 bp) region of DNA which might be located either upstream (mainly) or downstream of a gene so as to cause increased transcription. This particular region of DNA is known as enhancer and activator is also known as transcription factor. Activator is a trans-acting factor which binds to the cis-acting factor which is enhancer so as to enhance transcriptional expression.
But another protein named as effector may restrict activator from binding to the enhancer leading to a decrease in transcriptional expression by binding to the activator allosterically. Allosteric binding of effector to the activator causes conformational change in activator so it can no longer bind the enhancer.
Drag is another one i actually did this project in 5th grade so i know some of this hope this helps.
