Answer:
A Y-chromosome
Explanation:
Males have one X and one Y chromosome
Carl Woese distinguished between the members of the archaea and the bacteria using studies of their ribosomal RNA.
What is ribosomal RNA?
Ribosomal RNA (rRNA), a particle in cells that are sent out to the cytoplasm and is a part of the protein-creating organelle known as a ribosome, supports the change of courier RNA (mRNA) into protein. Moreover, ribosomal ribonucleic corrosive is a type of non-coding RNA that fills in as the primary structure block of ribosomes, which are essential for all cells. Protein combination is done by rRNA, a ribozyme, in ribosomes. In spite of never being converted into proteins, it makes up around 80% of cell RNA.

<span>The concentration of many people into the small area, for example, A city lowers the overall footprint of the population in the region.
Any pollution which results from people in a city can be isolated and treated more easily even than when people are being dispersed widely.
Many cities outlined suburbs to have a lower concentration of people because it can complicate public transport and provision of services. </span>
Answer: B
WHY?
Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.
Wegener supported his theory by means of demonstrating the Pangaea and geological similarities among continents. South America and Africa contain fossils of animals observed simplest on the ones two continents, with corresponding geographic levels.
Pangaea Wegener was satisfied that every one of Earth's continents have been as soon as a part of a good-sized, single landmass referred to as Pangaea. Wegener, educated as an astronomer, used biology, botany, and geology to describe Pangaea and continental drift.
The rock formations of eastern North the USA, Western Europe, and northwestern Africa were later found to have a not unusual starting place, and they overlapped in time with the presence of Gondwanaland. together, those discoveries supported the life of Pangea.
Wegener showed that positive styles of rocks on the continents would match with others in some other continents. What did Wegener realize approximately the oldest rocks on the African and South American continents? That they had been connected collectively whilst the continents were arranged to shape Pangaea.J
