Answer:
All the offspring have genotype RrTt
Phenotype is Pink and tall snapdragon
Explanation:
Given
Tallness ( T) is dominant to dwarfness (t)
Red (R) flower color is dominant to white (r)
It is given that heterozygous condition results in pink (Rr) flower color which means that the allels for color of flower show co dominance
Genotype of dwarf red snapdragon is RRtt
Genotype of a plant homozygous for tallness and white flowers is rrTT
The punnet square representing the cross between RRtt and rrTT is as given below-
Rt Rt Rt Rt
rT RrTt RrTt RrTt RrTt
rT RrTt RrTt RrTt RrTt
rT RrTt RrTt RrTt RrTt
rT RrTt RrTt RrTt RrTt
Thus all the offspring have genotype RrTt
Phenotype is Pink and tall snapdragon
Answer:
C
Explanation:
Protozoa have been classified into three trophic categories: the photoautotrophs which harness the sun's radiant energy in the process of photosynthesis; the photoheterotrophs, which although phototrophic in energy requirements, are unable to use carbon dioxide for cell synthesis and must have organic carbon compounds
The correct answer is protein.
Proteins are macromolecules composed of amino acids with the wide range of structures. Protein functions are diverse:
• structural proteins-maintaining the cell shape, (for example, proteins are structural elements in connective tissues like cartilage and bone in vertebrates),
• Enzymes - catalyze the biochemical reactions in cells-.
• Monitors- changing their activity in response to metabolic signals
• Part of the extracellular matrix or involved in intercellular communication…
