Answer:
1) Accommodation is the process of changing the shape of the lens to focus on near or distant objects.
- <em>To focus on a near object</em> – the lens becomes thicker, this allows the light rays to refract (bend) more strongly.
- <em>To focus on a distant object </em>– the lens is pulled thin, this allows the light rays to refract slightly.
2) - i don't know. im so sorry -
1. Nucleus step1: DNA is transcribed into mRNA
2. Ribosome step2: mRNA is translated into protein
3. Endoplasmic Reticulum step 3: Newly synthesised proteins are transported.
4. Golgi apparatus Step 4: Proteins are modified then transported away
In Golgi body or apparatus, the proteins are modified, sorted and packaging occurs for secretion.
Answer:
The archaea and the bacteria both are prokaryotes. However, the genetic makeup of the archaea is more similar to the eukaryotes. Moreover, they have differences, in their metabolic pathways, genes and the enzymes possessed by them.
Explanation:
The differences between Archaea and bacteria:
1. The cell wall of the bacteria consist of peptidoglycan, while the cell wall of the archaea consist of pseudo-peptidoglycan.
2. The bacteria are capable of spore formation, which can lie dormant for long periods of time until a suitable condition is found for their growth. The archaea are not known to form such spores.
3. The genes of the archaea are more similar to the eukaryotes than the bacteria.
4. The bacteria are found everywhere where the living conditions are suitable (soil, air, living beings, non-living things). the archaea are capable of surviving in extreme conditions (hot springs, salt brine).
5. The bacteria use the process of glycolysis and follows Kreb's cycle for glucose break-down. The archaea do not undergo glycolysis or Kreb's cycle.
