its c at the end of meiosis each gamete has two full sets of chromosomes
The first piece of evidence that needed to be found to support the endosymbiotic hypothesis was whether or not mitochondria and chloroplasts have their own DNA and if this DNA is similar to bacterial DNA. This was later proven to be true for DNA, RNA, ribosomes, chlorophyll (for chloroplasts), and protein synthesis.
Answer:
B. The chromosomes exchange genetic information.
Explanation:
Crossing over of tetrads during meiosis is very important for the exchange of genetic information.
This step of meiosis allows for each chromosome to be genetically unique and distinct from the others, creating genetic variation.
Crossing over does not double the number of chromosomes or reduce the number. The number of chromosomes stays the same.
So, the correct answer is B. The chromosomes exchange genetic information.
In an ideal situation, the producers include the trees, grasses and forests.
Building of roads and parking lots involve the clearing of forests and bushes.
Therefore there would be a decrease in number of producers. And ur answer is A.
