Romashka-Z-Leto [24]3 years ago
3 0

Answer:

<u>50%</u>

Explanation:

<em>Since</em> it was not a case of a Lettuce seed exposed first to <em>red light</em> and then to <em>far-red light</em> which will very likely not germinate because Pr (chromoprotein inactive form) absorbs red light efficiently, the light absorbed will convert a high proportion of the molecules to the Pfr (chromoprotein active form), thereby inducing germination. So there is a 50/50 percentage chance of of germination.

Describe how the functional units for beta carotene, xanthophyll, chlorophyll a, and chlorophyll b are different. be sure to ide
leonid [27]

The pigments have a similar structure of 40 carbon atoms covalently bonded in a chain. Carotenoids contain oxygen atoms in their chemical structure (retinyl functional group) while xanthophyll does not. This makes carotenoids more non-polar compared to xanthophylls, hence move farthest in chromatography paper using a nonpolar mobile phase. Chlorophyll pigment, on the other hand, has chlorin rings (which are larger) as functional units hence move slowly in chromatography.

Photosynthetic rates can be measured by either the amount of oxygen they consume per particular time period or the amount of carbon dioxide produced per particular time period. This is conducted while immersed in water so as to measure bubble rate formation in case of oxygen production or the change in water pH in the case of carbon dioxide consumption.

When autumn approaches, the amount sunlight received by the plant is reduced due to longer night than days. Deciduous trees have adapted by losing chlorophyll a and b pigments (most important in photosynthesis) during this time. This leaves a higher amount of the other red and yellow pigments hence making the leaves change from green to yellow-red.

It is believed that this is the result of an ancient endosymbiotic relationship between a protist and a eukaryotic cell. The protist generates energy that the eukaryotic can utilize in its growth and reproduction while the protist is sheltered. This relationship became obligatory symbiosis over time.

Hairpins often form at palindromic sequences in single strands of either rna or dna. however, several key features differentiate
AlekseyPX
Hairpin like structures are formed in both DNA and RNA but are common in RNA than in DNA. This is because DNA can be double stranded or single stranded while RNA is generally single stranded structure that can be double stranded only when it forms a hair pin like structure.
The features of hairpin structure in RNA are as follows:
1. This structure is a building block of many secondary structures of RNA.
2. The termination sequence during transcription also forms a hairpin loop like structure.
3. tRNA also forms a hairpin loop like structure and helps in the process of translation.
