Answer:
the process whereby nonsister chromatids exchange genetic material
Explanation:
Crossing-over is a unique phenomenon which occurs only in the prophase I stage of meiotic division i.e. meiosis I. It is the process whereby nonsister chromatids of homologous chromosomes (similar but non-identical chromosomes from male and female parents) exchange their genetic material.
This exchange between nonsister chromatids aids in genetic variation among species that reproduce sexually via meiosis. Hence, meiosis, which is peculiar to sexually-reproducing organisms is the only way that promotes genetic variation in species.
By classifying a limabean and wait for it to grow to classify it so it's way more easier to look at the pollen and that's how you classify pollen from a flower.!!!
Answer:
Chlorophyll a is the chief pigment associated with photosynthesis. As we can see,chlorophyll a absorbs red and blue wavelengths to a higher extent. Green light isn't rejected but rate of photosynthesis is more with red and blue wavelengths of light.
Explanation:
The spectral absorbance of photosystems and chloroplasts is lowest for green light...
All plants, however, has chlorophyll a, which absorbs most strongly at ~450 nm, or a bright blue color.
