An estuary is partly enclosed coastal body of water with one or more rivers flowing through it, and with a free connection to the open sea. it would be more of a collection. hope this help have a great day.

Explanation:
these are right i know for a fact.. had this unit for school
Answer:
B
Explanation:
Crossing over is the process involved during meiosis of two chromosomes sharing genetic information with each other from each parent. This happens so the two daughter cells or sister chromatids have a variety of genetic information and so they are not completely identical. This leads to genetic diversity or variation.
In natural selection, there are three main things you need to know. There must be a variance in the genepool of course, or else to selection or evolution will take place. There also must be a selective force and time. Now, lets say that there is a population of many colored moths. But lets say that the brown colored moth blends in with the environment. This means that predators (selective force in this case) will have a much harder time finding these brown moths instead of easily finding some of the other colored moths (variation). This means that the brown moths will survive at a much higher rate because the are harder to find, and over time, the gene pool will narrow down to just brown moths because the rest of the moths die out due to predators and competition. This also means that this moth species has evolved over time to just become the brown colored moths only. Hope you can understand this but feel free to ask for clarification.
Because the red eyes are recessive to black eyes, the parents could be heterozygous. Recessive alleles only show if two recessive alleles are combined. Thus the offsprings phenotypes of the gene would be C. Rr and rr
