Answer:
The bottom half
Explanation:
The lower half part of the iceberg displaces water equal in weight to the buoyant force.
What is Buoyant force?When an object is placed in a fluid, the fluid exerts an upward force we call the buoyant force. The buoyant force comes from the pressure exerted on the object by the fluid.
Because the pressure increases as the depth increases, the pressure on the bottom of an object is always larger than the force on the top - hence the net upward force.
The buoyant force is present whether the object floats or sinks. The object experiences forces on each of its six sides. On each side, the force is the pressure multiplied by the area of the side, and is directed perpendicular to the side and toward the inside of the object.
Therefore, The lower half part of the iceberg displaces water equal in weight to the buoyant force.

Final answer:
The abiotic element in the Southwestern desert ecosystem is the low and unpredictable precipitation. This affects both plant and animal adaptations, making them suited to the arid conditions.
Explanation:
The element in the Southwestern desert ecosystem that is abiotic is the precipitation pattern. Abiotic factors are the non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems. In the Southwestern desert, low and unpredictable precipitation is a significant abiotic factor that influences the biome. This arid region receives only about 8 inches of precipitation yearly, often in two seasonal patterns. The vegetation and animal diversity is closely adapted to these challenging conditions. For instance, plants such as cacti, sagebrush, and mesquite have deep roots, reduced foliage, and water-storing stems, while many animals exhibit nocturnal behavior or burrowing to escape the heat and retain moisture.

True or false the respiratory system gets rid of carbon dioxide from the body
based on their chemical formulas, which of these compounds is not likely to be an ionic compound: KBr, SO2, or AlCl3? explain your answer.
Sulfur dioxide (SO₂) is not likely to be an ionic compound because it is composed of two nonmetals, sulfur and oxygen, making it a covalent compound.
To determine which of the compounds KBr, SO₂, or AlCl₃ is not likely to be an ionic compound, we look at the types of elements involved. Ionic compounds are typically formed between metals and nonmetals. Potassium bromide (KBr) and aluminum chloride (AlCl₃) both have metals (K and Al, respectively) and nonmetals (Br and Cl, respectively), so both are likely ionic. However, sulfur dioxide (SO₂) consists of two nonmetals, sulfur (S) and oxygen (O), suggesting that it is not ionic but a covalent compound.
How can a single cell bacterium grow and reproduce exponentially
Single cell bacteria can grow and reproduce exponentially through binary fission, a process where one cell divides into two. Under ideal conditions, this can result in a large population increase, from 1000 to over 16 billion in just 24 hours. This results in a J-shaped growth curve showing the accelerating rate of growth.
A single cell bacterium can grow and reproduce exponentially through a process called binary fission. In ideal conditions, such as when a bacterial population is provided with an unlimited supply of nutrients, one bacterium can divide into two. This division can take as little as 20 minutes to an hour for many bacterial species, including E. coli. When 1000 bacteria are placed in a large flask with plenty of nutrients, the number of bacteria will double after just an hour. This exponential growth results in a geometric progression of population size because each successive generation doubles in number. The rate at which the population grows is accelerating, meaning that more organisms are added with each new generation.
For example, after one hour, 1000 bacteria become 2000. After two hours, the 2000 bacteria would become 4000, after three hours 8000, and so on. This exponential growth would result in the number of bacteria skyrocketing from 1000 to more than 16 billion in just one day, assuming they could divide every hour. Such rapid growth produces a J-shaped curve when the population size is plotted over time, illustrating the accelerating growth rate.
What is the primary determining factor that will or will not allow solute diffusion?
What are two secondary factors that affect solute diffusion?
The primary factor that determines whether solute diffusion will or will not occur is the concentration gradient, with molecules moving from higher to lower concentrations. Secondary factors include temperature and medium's molecule size, both of which can impact the speed of diffusion.
Explanation:The primary determining factor that will or will not allow solute diffusion is the concentration gradient. Diffusion is driven by a process of elimination where molecules move from an area of higher concentration to a lower concentration area, attempting to equalize the concentration throughout.
Two secondary factors that affect solute diffusion are temperature and medium's molecular size. The higher the temperature, the more kinetic energy the molecules have, which results in faster diffusion. On the other hand, the size of the medium's molecules can impact diffusion as well; larger molecules move slower than smaller ones, hence, they diffuse slower.

The human body is composed of cells, organs, organ systems, and tissues. How are these organized?
The human body is organized from simple to complex levels, starting with cells forming tissues, tissues forming organs, and organs forming organ systems, which make up the entire organism.
The human body is organized at different hierarchical levels of structural complexity, with each level building upon the one below it to create the intricate systems necessary for the body's function. The basic structural and functional unit of life is the cell. Groups of similar cells join together to form tissues, which are the building blocks for more complex structures in the body.
Tissues themselves are categorized into four main types: epithelial, connective, muscle, and nervous tissues. These tissues work in concert to construct organs, which are complex structures with specific functions, such as the heart, lungs, and brain. Each organ is typically composed of several different types of tissues arranged in a precise manner to carry out the organ's functions efficiently.
Multiple organs then combine to form organ systems, such as the skeletal system or the muscular system, which work together to perform functions necessary for life. The organization of these systems is such that they ensure homeostasis and allow for complex behaviors and processes in the body. In essence, cells make up tissues, tissues make up organs, and organs make up organ systems, which together create the complete organism, like a human being.
Why does the phase of the moon affect tides
Answer:
When lunar and solar tides act against each other, the result is unusually small tides, called neap tides. There is a new Moon or a full Moon about every two weeks, so that's how often we see large spring tides. When the gravitational pull of the Sun and Moon are combined, you get more extreme high and low tides.
