Answer: b. Necton

Explanation:

Necton is the term used to refer to aquatic organisms that are able to swim against the current of the water they are in. For this reason they are called "actively swimming" organisms. Aquatic plants that are unable to move against the current are called Plankton.

Fish, whales and dolphins are able to move against the current and so are classified as Necton. It is worthy of note however, that some organisms are able to transition from Plankton to Necton as they mature.

Which event might cause the carrying capacity of a population to change?
tamaranim1 [39]

Answer:

Carrying capacity can be described as the maximum number of population of a species that a particular habitat can hold.

There are a number of events which effect the carrying capacity like:

  • Environmental changes:

Environmental changes like weather conditions might become favorable for a species in a habitat. It might be that a certain weather condition raises more food for a species. Hence, the carrying capacity would increase.

It might be conditions like drought make the availability of nutrients scarce for a population of species. In this case, the carrying capacity of the ecosystem would decrease.

  • Other organisms :

It might happen that other species might come to live in the particular area. That species will deplete the availability of resources and cause the carrying capacity to decrease.

  • Water supply:

If adequate amount of rain fall occurs in an area, it might cause the carrying capacity of a species to increase as there will be more water. But if the water supply becomes scarce, the carrying capacity would decrease.

The phase during which sister chromatids aggregate along the equator of the cell is called ________
vova2212 [387]

The phase during which sister chromatids aggregate along the equator of the cell is called the metaphase.

The image shows the process of cell division through mitosis. The mother cell divides into two genetically identical daughter cells in mitosis. There are four main phases in the mitosis process. They are: prophase, metaphase, anaphase and telophase. In the metaphase, the highly condensed sister chromatids line up along the equator of the cell by binding to the microtubles that form the skeleton of the cell. These kinetochores line up the chromatids at the equator to initiate their separation.
