In communities where zebra mussels have invaded we observed that the population of invertebrates, zooplankton, and phytoplankton they will decrease when in open water. The population of bottom-dwelling invertebrates which are in the littoral zone will increase.
Hypothesis shows the zebra mussels will affect the fish negatively that feed on plankton in the open water but affect positively the fish which feed on invertebrates which are in the littoral zones.
The predictions by following the invasion of zebra muscles show that the number and growth rate of fish species in open water will decrease in population whereas the number and growth rate of fish species in the littoral zone will increase in population.
Answer:
it is that worker bee's work for the queen bee because the queen bee is really old while the worker bee's are young
Explanation:
Answer:
The sun is distibuted across the world due to The environment works in a similar way to a car's heat engine. Winds, precipitation, and evaporation processes in the atmosphere, on the other hand, spread the sun's energy across the Earth. Conduction, convection, and radiation are the methods through which heat energy is transferred.
Explanation:
I took earth science
This property allows fish living in lakes and ponds to survive the winter. The ice that freezes on the surface insulates the water below so it stays warmer! In general, it is extremely unusual for the solid phase of a substance to be less dense than its liquid phase, but lucky for aquatic life it is!
Answer:
Meiosis
Explanation:
Meiosis is one of the two types of divisions that cells usually undergo. However, meiosis is unique to sexually-reproducing organisms. Meiosis is the cell division which results in daughter cells with a reduced number of chromosomes (by half). Meiosis is used to produce gametes in sexually reproducing organisms.
According to the question, Labrador retriever contains 78 chromosomes in each of its muscle cells, which is a somatic cell. Since Labrador retrievers are sexually reproducing organisms, a male one will produce gametes (sperm cells) via the process of meiosis. At the end of the meiotic process, sperm cells with 39 chromosomes each will be produced.
