Answer:
B. rr
Explanation:
Genotype- Is the genetic makeup of an organism.
An homozygous individual is one who has similar allele e.g AA
It could either be in dominant form(AA) or recessive form(aa)
An heterozygote individual has two different allele in its genotype e.g Aa
A dominant gene is a gene that expresses itself in the phenotype of an individual while a recessive gene is a gene that is not expressed in the phenotype.
The genotype for a white homozygous flower is WW while the genotype for homozygous recessive is ww.
The dominant genotype is usually denoted with capital letter and the recessive is denoted with small letter.
Answer:
The law of conservation of mass
Explanation:
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction.
Answer: Option A and B.
Archaea and bacteria are prokaryote and reproduce by binary fission.
Explanation:
Archaea are grouped of single celled organisms that have no cell nuclei. They are prokaryotes and reproduce by binary fission. They were formally grouped as bacteria with the name archaeabacteria but the classification is outmolded. They are now renamed as archaea bacteria as they are closely related to eukaryotes.
Bacteria also are single celled, microscopic organisms. They are prokaryotes and they reproduce by binary fission. They have are number of shapes ranging from spheres to rods.
Enzymes (Catalysts) lower the required activation energy, allowing the reaction to happen more quickly.
Answer: Whether the culprit were too much sunlight or not enough, if photosynthesis stopped, plants would stop converting carbon dioxide -- an air pollutant -- to organic material.
