Answer:

When the volcano erupted, the dark red walking beans were easier to see. Thus, more dark red beans were eaten during days four, five, and six. If the pollution continued, there would be fewer and fewer dark red walking beans over time.

Why did bear island provide a great opportunity to decipher entire food chains?
Sergio [31]

Answer:

Due to the presence of limited number of species.

Explanation:

Bear island provide a great opportunity to decipher entire food chains because this island has many animals species which interact with each other or depend on one another due to the presence of less animals for feeding purpose. This island is isolated from the rest of the world so it provide a great opportunity to study the entire food chains that are present at that island. There is less number of species so knowing about their feeding choices is easier for the ecologists.

Describe how Stella’s view of these cells and their parts changed as she transitioned through the three levels of magnification.
Rudik [331]

Answer:

The paramecium body.

Explanation:

1. The objective lenses on a compound light microscope doess have powers that start of as smallest to highest power, 4x, 10x, and 40x on the maximum power setting. This means that the sample can be magnified either, 40x, 100x or 400x.

At 40x magnification Stella will see organism 5mm.

At 100x magnification Stella will be able to see organism 2mm.

At 400x magnification Stella will be able to see organism more closely, 0.45mm, or 450 microns.

2. Paramecia are shoe shape or molded and almost transparent and shrouded in a defensive pellicle.

Pellicle capacities like skin and shields them from the components. For movement they have cilia.

Heavy rains and mudslides cause a river to change course, isolating two groups of lizards from one another. If they remain isola
Stells [14]

If they remain isolated for a long period of time, the two groups will probably diverge genetically, and may result in speciation.

Genetic divergence is the process whereby two groups of the same ancestral species acquire autonomous genetic changes through time, usually after the groups have been separated reproductively for some period of time.

Speciation is an evolutionary process whereby populations develop to become different species.

iragen [17]

Explanation:

This statement is correct because the concept of integrating body and mind in physical activity was responsible for the expansion of physical activity, in addition to activities that promote only the well-being of the body aesthetically, but as a set of activities responsible for improvement of health, intelligence, emotional, creativity, as well as an instrument of social integration. The practice of physical activity releases endorphins in the brain, which is a natural substance produced by the brain that is associated with well-being, mood and joy, and this effect occurs during and after physical activity.
