17=3
18=4
I'm not that sure about 17, but I think it's right
Answer:
G and K
Explanation:
Crossing-over is a genetic phenomenon that occurs in meiosis, specifically, Prophase I. It is when chromosomal segment (genes) are exchanged between non-sister chromatids of homologous chromosomes. Crossing-over occurs only to genes that are UNLINKED i.e. genes located on different chromosomes or far apart on the same chromosome.
This unlinked genes are said to have the highest RECOMBINATION FREQUENCY. Crossing-over allows genes on the same chromosome but far apart from each other, assort independently, which allows alleles to be recombined on the same chromosome. This phenomenon does not occur to genes that are close on the same chromosome as they will be inherited together as a unit.
In this case, G and K are the farthest apart, hence, they will have the highest RECOMBINATION FREQUENCY i.e. the likelihood for homologous crossing-over to take place during meiosis.
Answer:
Genes are composed of DNA arranged on chromosomes.
Some genes encode structural or regulatory RNAs. Other genes encode proteins.
Replication copies DNA; transcription uses DNA to make complementary RNAs; translation uses mRNAs to make proteins.
In eukaryotic cells, replication and transcription take place within the nucleus while translation takes place in the cytoplasm.
In prokaryotic cells, replication, transcription, and translation occur in the cytoplasm.
Key Terms
DNA: a biopolymer of deoxyribonucleic acids (a type of nucleic acid) that has four different chemical groups, called bases: adenine, guanine, cytosine, and thymine
messenger RNA: Messenger RNA (mRNA) is a molecule of RNA that encodes a chemical “blueprint” for a protein product.
protein: any of numerous large, complex naturally-produced molecules composed of one or more long chains of amino acids, in which the amino acid groups are held together by peptide bonds

Answer:
h<em>Bacteria were first classified as plants constituting the class Schizomycetes, which along with the Schizophyceae (blue green algae/Cyanobacteria) formed the phylum Schizophyta.</em>
Answer:
○ D. Humans are using up natural capital faster than it is being replenished.
Explanation:
I assume this is the answer, due to the past/recent media on Earth and the economy.
