Hi
It is true that on the Galapagos islands Darwin observed tortoises with a dome and saddle shaped shells, you can see both in attached image.
Darwin observed that Galapagos Tortoises had the shells with different shapes depending on the Island they live, For example: The tortoises with saddle shaped shells were able to reach up to eat leaves of plants while the tortoises with dome shaped shells would not reach up and they would eat food from on ground sources. This made him think that the differences in tortoise shell is also a strong evidence that indicates that how tortoises have adapted themselves to better get their food as per the available resources and how they have evolved from same ancestral specie into two different species. This point also helped him in proposing the theory of evolution by natural selection.
Hope it helps!
Predators are the ones who consume the prey and rely on them as a food source, while prey rely on predators to control their population.
Answer:
1. Glycerol
2. Fatty acids
3. Monoglycerides
4. Triglycerides
5. Hydrocarbon
6. Hydrophobic
Explanation:
1. Glycerol
Fat consist of a molecule called glycerol that is attached to one, two, or three fatty acids. Glycerol is the basis of all fats and consists of a three-carbon chain that is attached to the fatty acids.
2. Fatty acids
Fats is made up of three fatty acids and a glycerol, it can also be called triacylglycerols or triglycerides.
3. Monoglyceride
It is a glycerol molecule with a singular fatty acid. It is formed through the combination of OH of glycerol to the OH of the fatty acid.
4. Triglycerides
It has three fatty acid molecules. It is a tri-esters made up of a glycerol attached to three fatty acid molecules.
5. Hydrocarbon
Fatty acids is made up of long, unbranched hydrocarbons with a carboxylic acid group found at one end.
6. Hydrophobic
The hydrophobic nature of fat arises from the carbon-hydrogen bonds that are nonpolar.
Answer:
Which best describes the law of independent assortment?
Alleles of a trait separate independently when gametes form.
Explanation:
I’m very sure it would be carbon dioxide, plants use carbon as part of photosynthesis, glucose is there food, oxygen is their afterproduct. So the answer is carbon dioxide
