Answer:
c. environmental effects.
Explanation:
Based on the information provided within the question it can be said that this scenario is a perfect example of environmental effects. This term refers to the effect that external factors or conditions have on something. Which in this case since the flower color depends on the external conditions (aluminum in soil) then it is an example of environmental effects on the flowers gene expression.
1. People should stop using things that need gas.
2. People should also stop trying to cut down too many trees to build more houses, factories, or shops of any kind.
These are the ways that I think that could reduce air pollution and slow the climate change.
I believe it would be 5g, because after 5 years, that 20 grams would be down to 10 (reduced by half). With the remaining 10 grams, you would take half of that 10 to find how much remains after another half life goes by. I hope this helps you!
Answer:
A tetrad is a four part structure formed during the prophase I of meiosis I which is formed by the homologous chromosomes which is composed of two identical chromatids.
The tetrad formation takes place when a proteinaceous meiosis-specific nuclear structures called synaptonemal complex is formed between two homologous chromosomes which mediates the tight associations of the homologous chromosomes.
The synaptonemal complex consists of two ladder like lateral elements which attaches the chromatin of the homologius chromosomes. The central region of the synaptonemal complex is composed of the transverse filaments and the central element which bridge the space between the the lateral elements.
This attachment of the chromatin to the synaptonemal complex mediates the chromosome pairing and form tetrad.
