Mitosis
Mitosis is the part of the cell cycle in which the duplicated genetic material (chromosomes) within the parent’s cell nucleus is separated to produce two daughter cells that are genetically identical to the parent. Mitosis is important to life because it is involved in the production of new cells for growth and to replace damaged cells. Mitosis occurs in five stages which are; interphase, prophase, metaphase, anaphase and telophase (cytokinesis).
Answer:
Nucleic acids are of two types DNA and RNA which are made up of monomeric units called nucleotides.
One monomer is one nucleotide which further consists of three parts:
1: Nitrogenous base
2: Sugar (a ribose sugar in RNA and a deoxyribose sugar in DNA)
3: Phosphate group
Explanation:
If we talk about single strand of nucleic acid DNA or RNA, there is a phosphodiester linkage that holds monomers together in a strand of nucleic acids. This phospho di ester linkage is formed when a condensation reaction occurs between a hydroxyl group of two sugars and a phosphate group.
You can see a better representation in attached figure.

Answer:
Oxygen (O2)
Explanation:
This question is describing photosynthesis which uses carbon dioxide and water as reactants in the presence of sunlight to synthesize sugar (glucose) and oxygen. The general equation is as follows:
6CO2 + 6H2O ---> C6H12O6 + 6O2
According to this question, a plant takes in 6CO2 molecules and 6H2O molecules in order to build one C6H12O6 molecule. Using the balanced equation above, the extra element is OXYGEN, which still needs to be released as a gas for the equation to be balanced i.e 6O2 molecules
The solution is hypertonic, and the cell will lose water.
A sea breeze describes the wind that blows from the ocean inland towards land. This breeze occurs most often in the spring and summer months because of the greater temperature differences between the ocean and nearby land, particularly in the afternoon when the land is at maximum heating from the sun.
During the day, the sun heats up both the ocean surface and the land. Water is a good absorber of the energy from the sun. The land absorbs much of the sun’s energy as well. However, water heats up much more slowly than land and so the air above the land will be warmer compared to the air over the ocean. The warm air over the land will rise throughout the day, causing low pressure at the surface. Over the water, the high surface pressure will form because of the colder air. To compensate, the air will sink over the ocean. The wind will blow from the higher pressure over the water to lower pressure over the land causing the sea breeze. The sea breeze strength will vary depending on the temperature difference between the land and the ocean.
At night, the roles reverse. The air over the ocean is now warmer than the air over the land. The land loses heat quickly after the sun goes down and the air above it cools too. This can be compared to a blacktop road. During the day, the blacktop road heats up and becomes very hot to walk on. At night, however, the blacktop has given up the added heat and is cool to the touch. The ocean, however, is able to hold onto this heat after the sun sets and not lose it as easily. This causes the low surface pressure to shift to over the ocean during the night and the high surface pressure to move over the land. This causes a small temperature gradient between the ocean surface and the nearby land at night and the wind will blow from the land to the ocean creating the land breeze.
