Answer:
DNA bases pair up with each other, A with T and C with G, to form units called base pairs. Each base is also attached to a sugar molecule and a phosphate molecule. Together, a base, sugar, and phosphate are called a nucleotide. Nucleotides are arranged in two long strands that form a spiral called a double helix.
A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base.

Explanation:
Answer:
The dinosaurs went extinct 65 million years ago. The Mesozoic Era lasted about 180 million years, and is divided into three periods, the Triassic, the Jurassic, and the Cretaceous. Each of these periods is divided into many epochs and ages. Mesozoic means "Middle Animal" and is sometimes called the age of reptiles.
Explanation:
Each spinal nerve consists of a dorsal and ventral root
The ventral root sends impulses from the central nervous system to its corresponding parts of the body. It is also called the anterior root or motor.
The symptoms will be:
- Loss of movement of the extremities
- radiating back pain up to the glutes, and leg pain
- Tremor and fatigue
Answer:
flux
Explanation:
- The rate by which the turnover of the molecules takes place in a metabolic pathway that regulates the flow of material is termed as metabolic flux or simply flux.
- The various enzymes that are involved in the metabolic pathway are responsible for regulating the flux.
- The flux varies with the different states of activity of a person and it is important for the regulation of metabolic activities as well as maintain the homeostasis of the body.
- The mathematical expression to calculate the flux is :
J = Vf - Vi
Where J = flux of metabolites
Vf = rate of the forward reaction
Vi = rate of the reverse reaction
Answer:
The correct answers are option b. "replication bubbles" and d. "replication forks".
Explanation:
The nucleic acids replication systems share some similarities between eukaryotes and prokaryotes. For instance, both organism have replication bubbles. However, prokaryotes have a single replication bubble because its replication process starts from a single origin, while eukaryotes have several replication bubbles. Also, the replication forks are well conserved from prokaryotes to eukaryotes with only some differences among the enzymes present within the fork.
