Respiration and Photosynthesis
Answer:
They are in organic
Explanation:
Vitamins are organic compounds derived from plants or animals that are needed in the body at small quantities.
They help in the body's metabolism since they enhance enzymatic activities and can act as co-factors.
They are essential for good health such as vitamin A helps in improving eye sight.
Lack of certain essential vitamins can lead to disease ,lack of vitamin D can lead to Rickets.
Answer:
warm air rising over land allows cooler air from the ocean to blow inland.
Explanation:
Answer:
2 meters (3 Gb of base pairs)
Explanation:
The human genome is composed of 3 billion (3 Gb) base pairs, which are organized in 23 pairs of chromosomes. Within the nucleus, DNA is compacted by histone proteins to form nucleosomes and these structures are then organized in chromatin fibers that undergone higher-order compaction. The compaction of chromatin fibers is accomplished by proteins and Matrix attachment DNA regions (MARs) that bind specifically to the nuclear matrix. In an unwound state, each cell nucleus in the human body has approximately 2 meters of DNA (if the DNA molecule would be stretched end-to-end).
Answer:
During synthesis phase DNA replication occurs to doubles the amount of DNA.
Explanation:
Interphase is the phase where the cell spends most of its time. Interphase is divided into three-phase which are G1, S, and G2 phase. The cell grows and produces enzymes required for DNA replication in G1 PHASE.
The synthesis (S) phase is the phase where the DNA replication takes place. Due to DNA replication, the amount of DNA gets doubled in this phase. DNA replication is important because after mitosis cell divides into two daughter cell in which the two DNA divides equally which creates two identical cell after cell division.
