Answer:
The DNA in eukrayotic cells is much more protected than the DNA in prokaryotic cells
Explanation:
DNA in eukaryotic cells lies within the nucleus. This DNA has a membrane protecting it from the outside. This means that the virus will have a harder time at getting to the DNA to insert its own DNA into it.
Prokaryotic cells have their DNA loose within the cytoplasm. This DNA is not protected. The virus will have to pass only 1 membrane in order to get to this DNA.
Answer:
For structural support: Nucleic acid.
For energy storage: Lipids or Carbohydrates. ( I'm kinda confused with this one since both do the job )
For membrane and barrier formation: Lipids or Carbohydrates. ( I'm kinda confused with this one since both do the job )
For Catalyst and biological formation: Protine
For Genetic information storage: Nucleic acid.
For Chemical signaling: Lipid.
Answer:
One advantage is that the exoskeleton provides a strong outer layer that acts as armor against predators and environmental hazards. Also serves as a water barrier and provides structure and mobility. disadvantages include less protection and leverage for muscles.
Explanation:
DNA replication steps. There are three main steps to DNA replication: initiation, elongation, and termination. In order to fit within a cell's nucleus, DNA is packed into tightly coiled structures called chromatin, which loosens prior to replication, allowing the cell replication machinery to access the DNA strands.
Answer: near methane clathrates and oil deposits.
Explanation:
Natural gas can be defined as a naturally producing hydrocarbon gas which consists of methane, higher alkanes, carbon dioxide, hydrogen sulfide, helium and nitrogen.
These are found near the hydrocarbon reservoir in the methane clathrates. These are the sedimentary structures which consists of compost of sea debris. The methane hydrates leak out from these structures and which liberates the methane gas in air.
The natural gas can also be found near the oil deposits.
