The major levels of organization of body, from the simplest to the most complex are atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.
Many individual organisms can be organized into the following levels are cells, tissues, organs, organs systems, and organisms. There are also levels of organization above the individual organism population, community, ecosystem, biome and biosphere.
Understanding the classification of these levels, provides context to the complexity of the human organism. The simplest level of organization is the chemical level of organization. At this level, simple atoms combine to form relatively simple molecules.

Which of the following is NOT a hypothesis about why the gas planets have rings?A. A moon broke apart and the debris formed ringsB. Orbiting debris from the planet's formation did not have enough gravity to formmoonsC. Small pieces of the planet broke off and were kept in orbit
All the four gas giants have rings and moons. Being theorized that the rings of Uranus, Neptune, and Jupiter are probebly a result of a meteor impact on their tiny inner satellites, forming rocky debris and dust that conitues to orbit the planet, while Saturn rings are made mostly of ice. however there is many theories, making difficult to be sure how those rings are formed. Between the alternatives the only that is not a hypothesis for why the gas planets have rings is: " Orbiting debris from the planet's formation did not have enough gravity to form moons" (b).

What causes cell division?The two distinct ways that cells divide are called mitosis and meiosis. Typically, mitosis—the process of creating new body cells—is what is meant when the word "cell division" is used. The process of cell division that yields sperm and egg cells is known as meiosis.
What is the proper order for the processes in cell division?There are six stages in this cycle: prophase, prometaphase, metaphase, anaphase, and telophase . Because cytokinesis is the final physical cell division after telophase, it is also referred to as the sixth stage of mitosis.
What mechanism divides cells?Cells divide in two different ways, mitosis and meiosis. The procedure of mitosis, which produces new body cells, is often when "cell division" is referred to. Meiosis is the name for the cell-division procedure that results in sperm and egg cells

Match the cell type (sex cell or somatic cell) with the examples provided.a. white blood cellb. spermc. egg (ova)d. hepatocyte (liver cell)e. epithelial (skin) cell
Sex cell is a gamete cell, used in sexual reproduction. which means that it will have half of the amount of chromosomes that other cells does, so it can merge with another sex cell and create a daughter cell (that is somatic) that has genetic material from both sex cells.
Somatic cell is every other cell, building our organs and our body, and it contains twice the amount of genetic material that's present in sex cells.
Therefore, we can match the examples as follows:
a. white blood cell - SOMATIC CELL
b. sperm - SEX CELL
c. egg (ova) - SEX CELL
d. hepatocyte (liver cell) - SOMATIC CELL
e. epithelial (skin) cell - SOMATIC CELL

Use the drop down menu to correctly identify steps in the water cycle.
The correct steps through which to identify the steps of the water cycle include:
Water moves from the hydrosphere to the atmosphere through evaporation.Water moves from the atmosphere to the lithosphere through precipitation.What is the Water cycle?The water cycle, also known as the hydrological cycle or hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth.
Water cycle stages
1. Evaporation
2. Sublimation
3. Condensation
4. Precipitation
5. Infiltration
6. Runoff
The water cycle has a huge effect o climate. For example, the greenhouse effect causes the temperature to rise. Without the cooling effect of evaporation from the water cycle, the Earth's temperature will rise dramatically.
The water cycle is also an integral part of other biogeochemical cycles. The water cycle affects all life processes on Earth.

How does contour plowing in farming help to prevent pollution?A. Contour plowing is used to reduce the amount of fertilizers used.B. Contour plowing is used to make insecticides less toxic.C. Contour plowing is used to reduce erosion and sediment pollution.D. Contour plowing is used to treat pathogens in livestock waste.
Plowing is a farming practice, that creates as its name says, contour lines, these lines are characteristic because they are placed perpendicular to the slope, for this reason, they are a method used to prevent erosion and retain water.
With this information in hand, we can see that option A is not correct because the use of plowing is related to soil loss and not to soil richness per se. Option B is not correct either because the use of insecticides is more related to the type of crop and surrounding vegetation cover. Option C in this case is the correct answer, it is used to reduce erosion and sediment pollution because helps retain soil. Finally, option D is not correct because this method is not related to livestock.

The given reaction represents the process of photosynthesis.
Photosynthesis is the process by which plants synthesize their food. During photosynthesis, plants use carbon dioxide and water in the presence of sunlight to manufacture glucose (sugar) and liberate oxygen.
The reaction for photosynthesis can be given by the following equation:-
6CO2 + 6H2O + light ----> C6H12O6 + 6O2
Photosynthesis generally occurs in the leaves (which contain chloroplasts) of plants. The gaseous exchange takes place by means of pores called stomata, which are present in the leaves. Water is taken by the plants through the roots with the help of a vascular system. The chlorophyll pigment that is present in the chloroplasts within leaf cells is responsible for capturing sunlight.
