Answer:
DNA has a double- helix structure which means it has two strands. The DNA strands are made from sugar (Deoxyribonucleic), phosphates and nitrogenous bases. There are 4 nitrogenous bases, 2 purine and 2 pyrimidine. The 2 purine bases are Adenine and Guanine. The pyrimidine bases are Thymine and Cytosine. DNA gives our genes.
RNA is a single strand unlike DNA. The strands are made from sugar (ribonucleic), phosphate and the nitrogenous bases. There are 4 nitrogenous bases 2 purine and 2 pyrimidine. The 2 purine bases are Adenine and Guanine. However, the 2 pyrimidine bases are Uracil and Cytosine. The function of RNA is to contribute to releasing proteins based on our rRNA and tRNA and mRNA. This process is known as RNA and transcription.
Explanation:
<span>Cork cells are plant cells on the outer edge of the trunks/limbs of woody plants. The cell wall is made of suberin, which doesn't let gas or water through. In essence, this helps keep the water in and unwanted things (like pathogens) out.
The inside of the cell is usually empty, but may have a few traces of things depending on species. These cells don't replicate and are generally considered to be dead.</span>
The correct answer would be
B. Fiber
Fiber is the indigestible portion of food from plants.
Can't see the chart. But chloroplasts, cell wall, central vacuole are only in plant cells
This is gravity.
Gravity is a force that is exerted on all objects on earth. The greater the mass, the greater the force of gravity is on an object.
