What effect did the introduction of the predators have on the bluegill population? was the hypothesis in the introduction correct? a. the hypothesis was incorrect; there is not enough data to determine the effect of predator introduction b. the hypothesis was incorrect; the population size increased c. the hypothesis was correct; the population size decreased d. the hypothesis was correct; population size remained the same submit for grading save and finish later?

a. the hypothesis was incorrect; there is not enough data to determine the effect of predator introduction

A hypothesis is a supposition or assumption of phenomena with limited evidences which needs to be justified or explained by experimentation and valid reasoning. An hypothesis remains uncertain until it is proved.The hypothesis was incorrect; there is not enough data to determine the effect of predator introduction . It is not giving any evidence about the predator prey relationship.

a. the hypothesis was incorrect; there is not enough data to determine the effect of predator introduction

Fish populations throughout the world have been affected by global warming including bluegill fish

Species in the same region tend to respond in a similar manner. Fish in the same family also show similarities in how they respond to change.

Fish Pests

Pests are intruding organisms that can prey, kill and affect fish productivity, both directly and gradually. Pests are predatory organisms, destroyers, and competitors. As a predator (predator organism), which is a creature that attacks and preys on fish which usually have a body size larger than the fish itself. Pests often attack fish when entering the aquatic environment that is being maintained by fish.

There are several ways you can do to prevent pest attacks on fish:

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
