Answer:
The true statement is: "Spring tides are the highest, while neap tides are the lowest."
Explanation:
- The range of difference in the level of water between high and low tide is always larger in spring tide.
- Neap tides are the moderate tides. It does not have huge difference in higher and low tides because the bulging of the ocean ( by the sun) balances the bulge of the ocean caused by the moon.
- This balance is not found in spring tides that is the main reason for spring tides to have the highest level for both higher and lower tides.
Answer:
ATP & ADP are nucleic acids.
Explanation:
ATP and ADP are macromolecules of nucleic acids as they are made up of structures similar to DNA.
An ADP molecule is made up of two phosphate groups, a sugar backbone (ribose) and the nucleotide adenine.
An ATP molecule is made up of sugar backbone, three phosphate groups and the nucleotide adenine.
Hence, Both the structures are similar to DNA and RNA. As the structures contain nucleotides hence ATP and ADP are nucleic acids macromolecules.
Electron transport chain (ETC) refers to a series of complexes involved in the transfer of electrons from electron donors to electron acceptors through the reduction and oxidation reactions.
The similarities between the ETC in mitochondria and chloroplasts are as follows-
1. Both involve the electron transport chains on their inner membranes.
2. The energy produced pumps the protons against their concentration gradient across a membrane.
3. ATP synthase is used.
4. Two protons provide energy for the production of three molecules of ATP.
The differences between the ETC in mitochondria and chloroplasts are as follows-
Mitochondria- It uses the process of oxidative phosphorylation and chemical energy from the reduction-oxidation reactions. The electron transport chain occurs in the cristae. The coenzymes involved include the NAD and FAD. ATP synthase is located in the cristae. The protons are pumped out of the matrix. The final electron acceptor is the oxygen.
Chloroplast- It uses the process of photophosphorylation and the light energy. The electron transport chain occurs in the thylakoid membrane. The coenzyme involved is the NADP. ATP synthase is located in the thylakoid membrane. The protons are pumped into the thylakoids. The final electron acceptor is the chlorophyll in cyclic photophosphorylation and NADPH+ in the non-cyclic photophosphorylation.
Answer:
25%
Explanation:
If they are both heterozygous, it means they both have a Dd genotype. If you draw out a punnet square Dd x Dd you end up with the following possible genotypes for the puppy:
DD, Dd, Dd, dd
In order for the puppy to be deaf, it must be dd since deafness is recessive, which is 1/4 (25%)
