Do you think that climate change has been presented to you as doom and gloom throughout your life? Explain.
Answer:
I believe that climate change is one of the most serious problems of young generations. At the current pace of greenhouse gas production global warming will increase exponentially, which will result in rising sea levels, certain animal species going extinct. Deforestation also severely adds to this problem as wood is a finite resource on Earth and the more trees we destroy the less oxygen there is relative to the amount of carbon dioxide in the atmosphere. This will continue to weaken the ozone layer which could result in catastrophe from sun flares or radiation. I do believe that in the near future drastic measures will be taken to prevent these events.

A cell has a 1% salt concentration. It is placed into a solution containing a 10% salt concentration.
What will happen to the cell?
Choose 1 answer:
Water will move out of the cell, causing it to swell.
Water will move into the cell, causing it to shrink.
Water will move into the cell, causing it to swell.
Water will move out of the cell, causing it to shrink.
Answer:
Water will move out of the cell, causing it to shrink.
Explanation:
When something with a low salt concentration is placed in a higher concentration of salt, the salt in the solution will try to suck out the water in the cell. Just remember why we hate salt, because it sucks! There's a little joke to help u remember. Thanks, Ms. Hoj :)
Answer:
CORRECT (SELECTED)
Water will move out of the cell, causing it to shrink.
Explanation:
The cell has lower concentration of solute and a higher concentration of water than the solution it is placed in. This means that water will move out of the cell, causing it to shrink.

Which of the following is always true of two organisms in
the same taxonomic class?
A.They can breed with one another
B.They have certain physical features in common
C.they evolved at the same time
D.they live in the same ecosystem
Answer:
they can breed with one another, they have certain physical features in common, they evolved at the same rate, they live in the same ecosystem. Lions and house cats share common features, but cannot breed with one another.
Explanation:
They share a common ecology, they may breed with one another, share some physical characteristics, evolve at the same rate, and inhabit the same ecosystem, hence option D is correct.
What are the taxonomic classes?If two species are members of the same class, they are also members of the same higher-level taxon. They share the same phylum and kingdom in this instance.
Kingdom, phylum or division, class, order, family, genus, and species are the seven main taxonomic ranks.
The taxon with the greatest number of species is the kingdom. In taxonomy, it is the broadest category into which the creatures can be divided.
The classification of five kingdoms was made by R.H. Whittaker. The kingdoms of Monera, Protista, Fungi, Plantae, and Animalia are included in this classification.
Therefore, option D is correct.

What is currently happening with Mount Etna?
Answer:
As Italy’s National Institute of Geophysics and Volcanology (INGV) explains on a recent blog post, the nascent eruption began on the night of May 29. Starting off by producing a thick column of ash rising from the New Southeast Crater, it gave way on May 30 to a far more lava-heavy display in the area, featuring two fissures blenching out lava.
Answer:
There is currently no eruptive activity at the volcano involving fresh lava and monitoring signals do not suggest an immediate change likely; only a weak thermal anomaly continues to be present from the southeast crater complex.

1. A. What is diffusion?
1. B. Use diffusion to
explain what happens when you drop a
sugar cube into a mug of hot tea.
2. A. What is osmosis?
2. B. Describe how water molecules
move through the cell membrane during
osmosis.
Answer:
Diffusion is the spreading of something more widely. When you drop a sugar cube in hot tea the sugar cube spreads out and the sugar starts to dissolve in the tea. Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. If the concentration of water molecules ouside the cell is lower than the concentration of water molecules outside the cell then the water moves out through osmosis. Water travels through the cell membrane.
