Answer:
Cohesion: Hydrogen Bonds Make Water Sticky
Explanation:
Cohesion: Hydrogen Bonds Make Water Sticky
In the case of water, hydrogen bonds form between neighboring hydrogen and oxygen atoms of adjacent water molecules. The attraction between individual water molecules creates a bond known as a hydrogen bond.
Answer:
Think about the crimes described in the video and about how crimes are investigated now. If the crimes happened today, the investigation will be based on fingerprint with evidence sample. Earlier also they used samples and scents to detect the crime.
Explanation:
If the crimes happened today suspects would be fingerprinted and would heck the crime scene for evidence such as blood, hair any type of DNA . Back then there wasn't a way of testing DNA and evidence they just investigated friends , family members and lovers . Back then they used blood hounds to sniff out scents of people who were suspects. Back then they also assaulted suspects until they would confess what they had seen or known .
The carbohydrates found in our genetic material are the two sugars deoxyribose and ribose.
Carbohydrates are defined as organic compounds which occur in food and living tissue and include starch, sugars and cellulose. They are composed of hydrogen, oxygen and carbon.
Deoxyribose is a sugar found in the structure of DNA, while the sugar ribose is found in the structure of RNA.
DNA is the molecule that carries the cell's genetic information while RNA is the molecule involved in synthesis of protein using the coded information received from DNA.
Both DNA and RNA are termed as the genetic molecules of life.
Answer/Explanation:
The DNA in all living organisms is made up of 4 bases, adenine, thymine, guanine, cytosine. The RNA replaces thymine with uracil, making 5 types of nucleotide. The number of nucleotide pairs in a genome can range from half a million up to 100,000 million - meaning there are an exponential number of combinations of these 4 bases.
Imagine an organism exists that has only 2 nucleotides (<u><em>this is over 200,000x smaller than even the smallest bacterial genome</em></u>). If we allow any nucleotide at each of the 2 positions, then we have 4x4 (4²) or 16 possible combinations of sequences. For a nucleotide length of 4, the total number of possible combinations are 4⁴ or 256.
Since we are dealing with many millions of nucleotides, there are essentially infinite combinations of nucleotides, giving rise to the variation that produces over 20 million organisms on the planet.
Answer:
Option (A)
Explanation:
The African plate is usually referred to as the fourth major (largest) tectonic plates that cover the continent of Africa and a portion of both the Atlantic and Indian ocean.
This plate shares a convergent plate boundary with the Eurasian plate towards its western side, where the African plate being denser subducts below the lighter Eurasian plate
It shares a boundary with the two smaller plates namely the Somalian and the Arabian plate towards its eastern side.
Thus, the correct answer is option (A).
