Explanation:
first - red
second- both red and pink
third - both red and pink
Necessary because it keeps heat in and keeps the planet at the right temperature for life.
It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming
Part 1:
A solution that causes a cell to swell is a hypotonic solution.
In an isotonic solution, there is no change in the size of the cell.
All three cause osmosis.
A solution that causes a cell to shrink is a hypertonic solution.
Part 2:
1. H. Energy
2.D. Endocytosis
3.G. Diffusion
4.B. Exocytosis
5.E. Facilitated Diffusion
6.A. Osmosis
7.C. Active Transport
8.F. Passive Transport
Sorry. I don't know how to explain part 3 ,but I tried and failed so I deleted it. Part 1 and 2 are correct though.
The cryosphere is the frozen water part of the Earth system. Beaufort Sea, north of Alaska. One part of the cryosphere is ice that is found in water. This includes frozen parts of the ocean, such as waters surrounding Antarctica and the Arctic.
Answer:
In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.
Euchromatin is a lightly packed form of chromatin that is enriched in genes, and is often under active transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus. 92% of the human genome is euchromatic.
The genes present in heterochromatin are usually inactive. The genes present in euchromatin are either already active or will be active during growth. Heterochromatin is transcriptionally-inactive. Euchromatin is transcriptionally. (This one here is the difference)
