Oils are lipids which are soluble in organic solvents and insoluble in polar solvents such as water. For saving on heating oil prices is to knock the lowering down temperature a few degrees. The Department of Energy research reports that for every degree cooler we can save between 1-3%.
what is polar and non polar solvent?Polar solvents have large dipole moments because they contain bonds between atoms with different electronegativity, such as hydrogen and oxygen.
Non polar solvents forms bonds between atoms with similar electronegativity, such as hydrogen and carbon.
It is possible to still keep oil heat bill down by looking into weatherproofing home, smartly using an efficient thermostat.

Explain how gases that producers need &
produce enter and exit the plant.
Answer:
Carbon dioxide and oxygen cannot pass through the cuticle, but move in and out of leaves through openings called stomata (stoma = "hole"). Guard cells control the opening and closing of stomata. When stomata are open to allow gases to cross the leaf surface, the plant loses water vapor to the atmosphere.

Answer:
D
Explanation:
They strain simply because these massive rocks are made up of obsidian mostly which is nearly impossible to break!
What causes the strain --
Elastic deformation is the dominant form of deformation at shallow depths in the crust and lithosphere because both the temperature and pressure are low.

Answer:
Oxygen is the CORRECT ANSWER
Explanation:
They produce oxygen by photosynthesis they take in carbon dioxide and make oxygen.
Cyanobacteria are photosynthetic marine organisms. why would these organisms likely be found only in shallow ocean zones? the current in deeper ocean zones is too traumatic. the amount of oxygen in deeper ocean zones is too high. the amount of light in deeper ocean zones is too dim. the amount of pressure in deeper ocean zones is too low.
Cyanobacteria as photosynthetic organisms would likely be found only in shallow ocean zones because the amount of light in deeper ocean zones is too dim.
What are cyanobacteria?Cyanobacteria are any of the very many photosynthetic prokaryotic microorganisms, of phylum Cyanobacteria, once known as blue-green algae.
Cyanobacteria are photosynthetic organisms, hence, require sunlight energy to undergo the process.
Light from the sun can only reach the photic zone of a water body, hence, cyanobacteria as photosynthetic organisms would likely be found only in shallow ocean zones because the amount of light in deeper ocean zones is too dim.

#SPJ4
Answer:
The amount of light in deeper ocean zones is too dim.
Explanation:
Not: the amount of oxygen in deeper ocean zones is too high, because their is barely any oxygen in deep ocean. Not:
The current in deeper ocean zones is too traumatic, it is very still, no currents.
The amount of pressure in deeper ocean zones is too low, there is high pressure deep ocean, like for example, when you go deeper in water your ears get filled, like you can't hear because of the high pressure.
So the answer is; The amount of light in deeper ocean zones is too dim.

Gene regulation is more
specific in eukaryotic
organisms because . . .
A. in multicellular organisms cells differentiate.
B. there aren't as many chromosomes.
C. they are single-celled organisms.
D. their DNA is much smaller than in prokaryotic organisms.
Answer:
A.) In multicellular organisms, cells differentiate.
Explanation:
A.) is correct because eukaryotes are multicellular organisms. Not all of these cells are located in the same place or serve the same function. Because of this, many cells need to differentiate. When organisms have more specialized cells, they need to have more complex gene regulation processes in order to create these cells and control their behavior.
B.) is incorrect because eukaryotes have more chromosomes than prokaryotes. While prokaryotes only have one circular chromosome, eukaryotes can have many more depending on the species.
C.) is incorrect eukaryotes are not single-celled organisms. Eukaryotes are multicellular organisms and prokaryotes are single-celled organisms.
D.) is incorrect because eukaryotes have a lot more DNA than prokaryotes. This makes sense because eukaryotes are more complex than prokaryotes.
Answer: A. in multicellular organisms cells

Answer:
It's A. Monocot
Explanation:
Explain/identify each phase of the cell cycle. (interphase + mitosis + cytokinesis).
Answer:
Interphase is when cell grows, replacing it chromosomes while preparing for cell division.
Mitosis - copies its chromosomes and then segregates them, generating two identical nuclei.
Cytokinesis - the cytoplasm splits in half to make two new cells.

how does climate change relate to fairness and development?
Answer:
Climate change aggravates the effects of population growth, poverty, and rapid urbanisation. Without serious adaptation, climate change is likely to push millions further into poverty and limit the opportunities for sustainable development and for people to escape from poverty.
Fairness in Adaptation to Climate Change looks at the challenges of ensuring that policy responses to climate change do not place undue and unfair burdens on already vulnerable populations.

Write “D” if for DNA, “R” if for RNA, or “BOTH” if it pertains to both DNA and RNA.
1 ._________ I am a nucleic acid.
2 ._________ I am usually single - stranded.
3 ._________ I am generally found both in side and outside of the nucleus [in eukaryotic cells].
4 ._________ I am arranged as a double helix , and my shape is often described as a “twisted ladder.”
5 ._________ I include bases guanine, cytosine, and adenine .
6 . ________ Each of my nucleotides includes a phosphate, sugar, and base .
7 ._________ I include the base uracil .
8 ._________ I include the base thymine .
9 ._________ I generally remain in the nucleus [in eukaryotic cells].
10 .________ I have the sugar deoxyribose.
11 .________ I am made up of nucleotides .
12 .________ I have the sugar ribose .
Answer/Explanation:
1. Both because RNA and DNA consist of Adenine, Uracil, Guanine, Cytosine, and Thymine which are all nucleic acids
2. R. RNA is usually single stranded while DNA is double stranded getting the name the "double helix"
3. D. DNA can usually be found in the nucleus of a cell but can sometimes be found in the mitochondrion of that cell which is outside of the nucleus
4. D. DNA got the name double helix because of its ladder like shape. The shape of DNA looks like ladders curling around a pole
5. Both. This is because both RNA and DNA consists of these nucleic acids but the acids that make then unique are the uracil in RNA and the thymine in DNA
6. Both. This is because all nucleotides consist of a phosphate, sugar, and a base. Thats what makes up a nucleotide
7. R. As it was said earlier, RNA has the same nucleic acids as DNA except uracil. DNA has thymine instead of uracil
8. D. DNA has thymine instead of uracil
9. Both. Both DNA and RNA are usually in the nucleus doing their jobs to help us function
10.D. DNA has sugar deoxyribose while RNA has sugar ribose.
11. Both. Both DNA and RNA are made up with nucleotides like thymine, uracil, adenine, and more
12. R. Only RNA has sugar ribose since DNA has sugar deoxyribose

If you were to observe the activity of methylated dna, you would expect it to _____.
If you observe the activity of methylated DNA, you would expect the change in the activity of DNA molecule.
What is the activity of methylated DNA?DNA methylation is a process by which methyl is added to the DNA molecule which can change the activity of a DNA without changing the sequence. When it is located in a gene promoter, DNA methylation acts to repress gene transcription.
So we can conclude that If you observe the activity of methylated DNA, you would expect the change in the activity of DNA molecule.
