Answer:
This is due to the general nature of the body's features.
Explanation:
The traits are important in the survival of the creatures. For example, a keen vision is needed to spot prey that is several meters or kilometers away. In addition, the claws serve different functions. For example, the claws are there to rest on the patch of the tree and hold firmly. In addition, the claws are for tearing prey. Further, the claws are for holding and lifting prey and suffocating it if necessary.
Answer:
Sand Dunes serve an important purpose by protecting inland areas from coastal water intrusion. They are able to absorb the impact and protect inland areas from high energy storms and act as a resilient barrier to the destructive forces of wind and waves.
Explanation:
7. Adenine (A), Guanine, Cytosine and Thymine are the four nitrogenous bases in DNA.
8. In DNA Cytosine always forms hydrogen bonds with guanine.
9. The sequence of nucleotides carries the genetic information of an organism.
10. The process of replication produces a new copy of an organism's genetic information which is passed on to a new cell.
11. The double-coiled shape of DNA is called a double helix
Explanation:
There are four nitrogenous bases in the DNA of an organism. Two of the bases are pyrimidines eg: Thymine and cytosine while 2 of the bases are purine bases namely adenine and guanine. The purine of one strand forms a hydrogen bond with pyrimidine of the parallel strand of DNA.
The bases are present in nucleoplasm as dNMPs and in DNA they are present as dNTPs (deoxyribonucleotide triphosphate). During replication, these dNMPS keeps on bonding with other dNMPs in the presence of ATP and as DNA Polymerase, ligase topoisomerase etc. These nucleotides form the DNA strands and they are responsible for coding proteins. The sequence of DNA is also termed as gene.
The double helix structure of DNA was given by Watson and Crick. Each strand has an alternative backbone of sugar and phosphate group. The four bases bonds with glycosidic and phosphodiester bonds with sugar and phosphoric acid.
The equation for photosynthesis states that the combination of carbon deoxide,
water and light energy produces a carbohydrate and oxygen. the chemical formula for example is 6co2+6h20+light energy=c6h12o6+6o2. hope it helps.

After development of Robert Hooke's light microscope, early elements of the cell theory were proposed. The invention of light microscope made it easy to study the structure of microscopic cell. After deciphering the cell structure with the help of a light microscope the cell theory was proposed. The invention of microscope was a big break through in the scientific world as it enabled researchers to study the microscopic structure. Later, the microscopes were modified to study the cellular organelles and prokaryotic microorganisms.
Cell theory provides the foundation for the study related to cells such as molecular biology, cell biology, etc.
