Answer:
Explanation:
Haploid Cells
Haploid cells contain only one set of chromosomes. Gametes or sex cells are the most common type of haploid cells. They are produced by meiosis and are genetically diverse. When the haploid cells from male and female fuse together during fertilization, it forms a diploid cell.
Diploid Cells
These cells have two sets of chromosomes. It is formed by the fusion of two haploid cells. Most mammals are diploid, i.e., they have two homologous copies of each chromosome in the cells. They are produced by mitosis. The somatic cells in humans are diploid cells.
Answer:
A. long (front-to-back), vertically low skull shape
Explanation:
- The Neanderthals had a different body structure than doe the present modern humans have. The had a more robust well-built structure and had a distinctive morphological feature.
- Research suggests they were stronger than modern man thought they were slightly shorter than modern humans. They had a noticeable face, a chin, and a forehead slope.
Answer:
Hydrogen sulfide or methane
They use methane as an energy source
Answer:
The answer is - Although their cell structures are very different, archaean and eukaryotic cells are more closely related to each other than to bacteria, as evidenced by the fact that Bacteria was the first domain to split from the shared ancestor of Archaea and Eukarya.
Explanation:
The options are:
A. Bacterial and eukaryotic cells are more closely related to each other than to archaeans, as evidenced by the fact that bacteria and eukaryotes do not inhabit the most extreme environments.
B. Although their cell structures are very different, archaean and eukaryotic cells are more closely related to each other than to bacteria, as evidenced by the fact that Bacteria was the first domain to split from the shared ancestor of Archaea and Eukarya.
C. Bacteria and archaeans are more closely related to each other than to eukaryotes, as evidenced by their cell structures. Bacteria and archaeans are prokaryotic, while all eukaryotic cells contain mitochondria and other membrane-bound organelles.
D. The three domains of life are equally divergent from one another, so no two domains are more closely related to each other. This is supported by the evolutionary tree of life because three branches extend from one node millions of years ago.
The answer is - B. Although their cell structures are very different, archaean and eukaryotic cells are more closely related to each other than to bacteria, as evidenced by the fact that Bacteria was the first domain to split from the shared ancestor of Archaea and Eukarya.
Archaea and bacteria are similar in terms of cellular organisation and size but are however similar to eukaryotes (eukarya) at the molecular level. Archaea and Eukaryotes both undergo DNA replication and protein synthesis the same mechanism. Both of them posses closely related genes and several metabolic pathways, including the enzymes in transcription and translation.
A country like China would probably be in Stage 4 of the population with the low birth rate and low death rate due to their economic power have technology to prolong and save their citizen from diease and condoms
