In plant seeds, the photoreceptor phytochrome is responsible for the process termed photomorphogenesis<span>. This occurs when a seed initially situated in an environment of complete darkness is exposed to light. A brief exposure to electromagnetic radiation, particularly that whose wavelength is within the red and far-red lights, results in the activation of the photorecepter phytochrome within the seed. This in turn sends a signal through the signal transduction pathway into the nucleus, and triggers hundreds of genes responsible for growth and development</span>
Well there part of a group called carbohydrates ,sugars are monosaccharides, or single units of a specific molecules such as gluclose,fructose,and monasse . startches on the other hand ,are polysaccharides ,long chains of chains of single sugar molecule subunits linked together, if this doesnt answer your question just txt me,thxs love
Answer:
Ethylene
Explanation:
Ethylene is a hormone required to trigger fruit ripening, and it can be blocked by using synthetic compounds, such as 1-methyl-cyclo-propene (1-MCP).
The answer is b, numerous meaning more in amount
D. DD = 0.0225; Dd = 0.1275; dd = 0.7225
The value of Dd is different in question.
<u>Explanation:</u>
Given -
Dark colored = DD, Dd
light colored = dd
Frequency of allele D = 0.15
Frequency of allele d = 0.85
Hardy-Weinberg equilibrium is applied.
DD = 0.15 X 0.15 = 0.0225
Dd = 0.15 X 0.85 = 0.1275
dd = 0.85 X 0.85 = 0.7225
Therefore, DD = 0.0225; Dd = 0.1275; dd = 0.7225
