Answer: Tsunami from earthquakes below the surface of the ocean.
Unexplained changes in wind and tide changes
Explanation:
Answer:
Plants are multicellular eukaryotes. They have organelles called chloroplasts and cell walls made of cellulose.
Plants also have specialized reproductive organs.
Almost all plants make food by photosynthesis.
Life as we know it would not be possible without plants.
Answer: C). Neurons
Explanation:
Neurons are the specialized cells present in the brain. These cells play an important role in processing and transfer of information generated as a response to stimuli. The neurons have specialized parts which recieves the signals from dendrites and send the signal to other neuron by axon. In this way transfer of information takes place from cell to cell.
Answer:
The primary defined divisions of time are eons, in sequence the Hadean, the Archean, the Proterozoic and the Phanerozoic.
Explanation:
Answer:
1. Carbohydrate
2. Carbohydrate
3. Lipids
4. Proteins
5. Nucleic Acids
6. Lipids
7. Proteins
8. Nucleic Acids
Explanation:
1. Carbohydrate is used as primary source of energy in cells as each sugar molecule in carbohydrate breaks and form high energy ATP, which is primary energy utilized by all cells.
2. Carbohydrates have the basic formula CH2O as carbohydrate is composed of of carbon and a 2:1 ratio of hydrogen to oxygen.
3. Lipids or fatty acid can be saturated or unsaturated, it depends on the number of hydrogen in the tail. Saturated fatty acids have single bonds while unsaturated fatty acid have some missing hydrogen in tail and form double bond.
4. Enzymes are example of proteins because enzymes are made up of many amino acids binded in a very specific and unique order and amino acid are building blocks of proteins.
5. Nucleic acid is the monomer consist of nucleotide as all nucleic acids are made up of same five pieces are uracil, guanine, thymine, cytosine, and adenine.
6. Lipids are considered as hydrophobic as it is composed of carbon and hydrogen and have mostly nonpolar carbon–hydrogen or carbon–carbon bonds.
7. Proteins are most complex macromolecules as they made up of hundreds of amino acids and each amino acid has its own specific shape. All the properties of proteins depends on these specific amino acids
8. when some one look into mirror, they see their own image or phenotype characters which are due to the genetic makeup in the body. DNA is responsible for the phenotype and genotype where DNA is a nucleic acid. Hence, the , one will see while looking in the mirror is nucleic acid.
