Answer:
ughh thanks........because I already give up!!!!!!!
Explanation:
Answer:
1. Cells are composed of chemicals and both the structure and function of cells are regulated by the basic principles of chemistry. true
2. Scientists have successfully sequenced the entire genome of humans but have not yet sequenced the entire genome of any other species. false
3. Living systems are the most complex chemical systems on earth. true
4. Living systems are governed by the same principles of chemistry and physics that govern non-living systems. true
5. Living organisms contain unique chemical elements which are not found in non-living systems. false
6. An input of energy is required to maintain the complexity of living systems. true
7. The energy conversions that take place in living systems are governed by the same laws of thermodynamics that govern non-living systems. true
Explanation:
Cells are the basic unit of life which differentiate a living thing from a non- living thing. Although a living system, is made of the same chemical elements from which a non-living t=might be made, yet they are different from the non-living things as living things carry out the seven basic principles of live.
All living things carry genetic material from which their genome is made. Scientists have currently been able to sequence the genome of humans as well as many other organisms.
Answer:
DNA polymerases
Explanation:
DNA polymerases are a family of enzymes that carry out all forms of DNA replication.
Answer:
Ball-and-stick models show the bonds between atoms, but not the relative sizes of the atoms. Space-filling models show the relative sizes of atoms, but not the bonds between atoms.
Explanation:
Chemically, it is hard to understand the complex structure and shapes of the atoms and molecules. For better understanding, scientists have different models that help show the molecules in different prospects. For example, ball-and-stick and space-filling models.
The ball-and-stick model shows the three-dimensional arrangement of atoms and bonds. This model has a limitation that the identification of atoms requires a key to color representations. This model also does not show the relative size of atoms.
The space-filling model shows a three-dimensional arrangement as well as the relative size between atoms. Bonding between atoms can sometimes be difficult to distinguish in this model.
