:

D. Both competition and environmental filtering shape community structure.

Explanation:

Based on competition theory,  two  organisms occupying the same ecological niche can only coexist   provided  there is spatial or conditioning niche partitioning.This  prevent  competitive exclusion , ensuring survival of the two species in their niche. Since the two species developed greater variability in (over-dispersed traits)  to resist the selection  pressure,(competition).Many overdisperesed traits is present in the communities.

  However environmental filtering, is concerned with selection of species with  natural ability or triats to survive in a given communities,Thus if two species of organism  meet the same ecologocal requirements in a community, environmental filtering, fitters them and ensure their survival ahead of others who do not meet the requirements, and could not survive.

Thus the simultaneous operation of theses  two opposing selection pressures, structured communities ensuring coexistence and favoured ability of organism to survive.

What do isobars represent on a weather map?
alisha [4.7K]
Isobars represent adjusted atmospheric pressure. This removes pressure discrepancies caused by the location's relation to sea level or altitude. Isobars are also adjusted when necessary so that they never cross or touch. Weather maps with isobars give pressure information at a glance. They also give an approximation of wind direction because wind moves from high-pressure areas to low-pressure areas as large air masses move through the pressure differential.

What is the empty structure in the cytoplasm
qwelly [4]
The Golgi bodies are the empty structure in the cytoplasm. The Golgi apparatus or Golgi complex is found in most cells. It is another packaging organelle like the endoplasmic reticulum<span> (ER). It was named after Camillo Golgi, an Italian biologist. It is pronounced GOL-JI in the same way you would say squee-gie, as soft a "G" sound. While layers of membranes may look like the rough ER, they have a very different function. </span>

storchak [24]

Answer:

ppss and PPSS

Explanation:

Just as indicated in the question above, Flies homozygous for singed and purple were crossed with flies that were homozygous for normal bristles and red eyes.

And a Drosophila mutation called singed (s) causes the bristles to be bent and misshapen.

A mutation called purple (p) causes the fly’s eyes to be purple in color instead of the normal red.

Thus, the genotypes of the parental flies in Cross 1 are
