The correct answer is A. Incomplete dominance
Explanation:
Incomplete dominance occurs in genetics when two alleles lead to a new observable trait (phenotype), this occurs because the two alleles (variants of genes) combine or express at the same time, and therefore neither of the alleles shows a complete dominance. This type of dominance differs from codominance because in codominance both alleles express equally without combining or creating a new phenotype.
The case presented is an example of incomplete dominance because the allele that leads to black coat and the one that leads to white coat are combining, and therefore none of the alleles is completely dominating; also, in this case, there is a new phenotype or trait, which is the gray coat of the offspring that results from combining black coat and white coat alleles.
Can you please help me with this, that'd be great! Thanks!
The correct answer is insertion mutation.
The mutation is defined as the change in the DNA (deoxyribonucleic acid) sequences. The insertion mutation is a type of mutation, in which the insertion of the nucleotides takes place in the DNA sequences, resulting in an increase in the total number of base pairs in the DNA sequence. So, the insertion mutation has resulted in the increase in the base pairs in this case.
Which of the following statements is true?
All mutations are harmful.
Mutations are the only way to add new genes to a gene pool.
In substitution, DNA base pairs are deleted or lost during replication.
A mutation in the liver cell of a cat will be inherited by the cat's offspring.
Answer:
Mutations are the only way to add new genes to a gene pool.
Explanation:
Answer:
Each nucleotide base can hydrogen-bond with a specific partner base in a process known as complementary base pairing: Cytosine forms three hydrogen bonds with guanine, and adenine forms two hydrogen bonds with thymine. These hydrogen-bonded nitrogenous bases are often referred to as base pairs.
Photosynthesis
Ocean storage
Fossil fuel emissions
Transpiration
Answer: The balanced chemical equation for photosynthesis is 6CO2 + 6H2O + sunlight --> C6H12O6 + 6O2.
The balanced chemical equation for cellular respiration is C6H12O6 + 6O2 --> 6CO2+ 6H2O + Energy.
Explanation: Photosynthesis and cellular respiration are two opposite reactions. In photosynthesis, plants use carbon dioxide, water and sunlight to produce glucose and oxygen while in cellular respiration, both plants and animals breakdown glucose in the presence of oxygen to produce carbon dioxide and water with the release of energy.
Photosynthesis occurs only in plants and some photosynthetic bacteria while cellular respiration occurs in both plants and animals. The energy released from the breakdown of glucose in cellular respiration is used to drive other cellular processes.
Each of the two processes depends on the other for the supply of its reactants. Photosynthesis depends on cellular respiration for the supply of carbon dioxide and water while cellular respiration depends on photosynthesis for the supply of glucose and oxygen.
The balanced chemical equation for photosynthesis is 6CO2 + 6H2O -> C6H12O6 + 6O2. The balanced chemical equation for cellular respiration is C6H12O6 + 6O2 -> 6CO2 + 6H2O. These equations represent the conversions that occur in photosynthesis and cellular respiration.
The balanced chemical equation for photosynthesis is. The equations represent the conversion of carbon dioxide and water to glucose and oxygen in photosynthesis, and the reverse conversion of glucose and oxygen to carbon dioxide and water in cellular respiration.
6CO2 + 6H2O → C6H12O6 + 6O2
The balanced chemical equation for cellular respiration is:
C6H12O6 + 6O2 → 6CO2 + 6H2O
The equations represent the conversion of carbon dioxide and water to glucose and oxygen in photosynthesis, and the reverse conversion of glucose and oxygen to carbon dioxide and water in cellular respiration.
