Answer: Homologous chromosomes
Explanation:
Homologous chromosomes are the pair of chromosomes that are contained in diploid organisms such as humans. There are 23 pairs of homologous chromosomes, and 46 in total (44 non-sex chromosomes and 2 sex-chromosomes)
During gamete formation, the mother produces an egg cell with 23 chromosomes, and the father produces a sperm cell with 23 chromosomes. Both combines, fertilize and yield a single cell known as Zygote with 46 chromosomes (i.e 23 pairs of homologous chromosomes)
Answer:
most algae are autotrophs or more specifically, photoautotrophs
Explanation:
Answer:
The geologic time scale was developed after scientists observed changes in the fossils going from oldest to youngest sedimentary rocks. ... Later, scientists used absolute dating to determine the actual number of years ago that events happened. The geologic time scale is divided into eons, eras, periods, and epochs.

Answer:
It could lead to several later problems in the cell.
Explanation:
Removing a piece of DNA could severely affect the cell but it could also cause nothing. Depending on the part that is damaged, it could codify for a vital protein but it could also be an intron, which are pieces of DNA that don't codify for any protein. This has been recently researched and even though there are introns that could cause some serious trouble, most of them are an unknown matter to nowadays scientists. Anyway, a wrongly repaired sequence could end in a mutation that can potentially damage the cell and therefore the organism.
