C.All people and cultures have access to the same resources. D.Many types of resources are unevenly distributed across the world.
The answer is D. Many types of resources are unevenly distributed across the world or Some resources are plentiful only in a few areas.
both for apex just depends on which answer choices you are given
i took the test so i hope it helps
Answer: D. Many types of resources are unevenly distributed across the world.
Natural resources are those material or entity obtain from natural environment sources. Based on their origin resources can be classified into: Abiotic Resources (non- living resources like water, soil etc) and Biotic Resources (living resources like plants, animal, humans etc). Resources can be classified on the basis of their availability: renewable and non-renewable resources. Renewable resources are those which can be replenished and reproduced relatively quickly. For example, agricultural crop. Non-renewable resources are those which are produced after millions of years and they cannot be reproduced and replenished quickly. For example, fossil fuels. Resources can be classified on the basis of their distribution: Ubiquitous resources (these are abundantly present in the world example air, water, light) and Localized resources (these are only found in certain parts of the world example coal, copper, iron ore etc). Therefore, resources are found unevenly distributed across the world.
which of the following is not involved in controlling buoyancy in fishes
Buoyancy in fishes is regulated by the swim bladder, not by gills which are used for breathing and are not involved in controlling buoyancy.
The student asked which of the following is not involved in controlling buoyancy in fishes. Buoyancy control in bony fishes is primarily handled by a specialized structure called the swim bladder, a gas-filled organ that allows the fish to maintain its position at different water depths without expending energy swimming. The swim bladder functions by varying the amount of gas it contains, which alters the fish's buoyancy. Additionally, gills are used for breathing by drawing water over them, which are covered by a muscular flap known as the operculum. Thus, gills, while crucial for gas exchange, are not directly involved in controlling buoyancy.
Members of The same community always belong to The same
Final answer:
Community membership is characterized by shared norms and values that facilitate a sense of solidarity and unity within a group. The concept of 'Gemeinschaft' highlights how communal bonds are formed, transcending individual self-interest for the good of the group. Individuals often belong to multiple communities concurrently, based on various facets of their lives.
Explanation:
Members of the same community often have a shared set of values or priorities, which serves as the basis for their association. This concept, known as Gemeinschaft, describes a social group where individuals are connected through common norms due to shared experiences, physical space, or beliefs. These communities can include family, ethnic groups, religious congregations, or national communities, and they reflect a strong sense of togetherness and mutual bonds, forming a collective identity.
In these communities, such as those formed around hobbies like sports or music, age, career, or even shared geography, members are often more oriented to the will and good of the group than their own self-interest. They participate and contribute based on common mores or beliefs about appropriate behavior and responsibilities, nurturing a sense of solidarity and unity.
Ultimately, members of the same community do not always belong to just one community; they are part of multiple groups in different contexts of their lives, which can include political parties, sports teams, and various societal groups. It's their shared culture and experiences that help solidify their membership within a specific community, as they work in unity and support the collective goals of the group.

why doesn't asexual reproduction result in variation among offspring and parents?
There is no mating or mixing of genetics in asexual reproduction. Asexual reproduction results in a clone of the parent; the offspring has identical DNA as the parent. There is usually no variation from generation to generation in a species population that relies on asexual reproduction.
One way for an asexually reproducing species to get some diversity is through mutations at the DNA level. If there is a mistake in mitosis or the copying of the DNA, then that mistake will be passed down to the offspring, thereby possibly changing its traits. Some mutations do not change the phenotype, however, so not all mutations in asexual reproduction result in variations in the offspring.
Which property would have the greatest percentage of runoff?
A. 75% of the area is vegetation and 25% is roofed or paved
B. 25% of the area is vegetation and 75% is roofed or paved
C. 50% of the area is vegetation and 50% is roofed or paved
D. All of the above will have the same runoff
Answer: The correct option is B. 25% of the area is vegetation and 75% is roofed or paved.
Vegetation can cause precipitation and reduce runoff. Leaves and stems are used in capturing rain and prevents the rainwater to reach the ground. Dense vegetation with higher surface area under vegetation absorbs water and prevents runoff. Pavements or roofs cause the runoff water by filling the waterways as there is no vegetation for water absorption which leads to overfilled waterways and in turn cause flooding.

Jack has a condition where mucus builds up in his lungs. This makes it more difficult for gas exchange to take place. Which two organ systems are primarily affected by this?
The two organ systems primarily affected by the condition where mucus builds up in Jack's lungs are the respiratory system and the immune system.
What is the role of a respiratory system ?The respiratory system is responsible for gas exchange, where oxygen is taken in and carbon dioxide is eliminated from the body. In Jack's case, the mucus buildup in his lungs can make it more difficult for this gas exchange to occur, as it can block the airways and reduce the surface area available for gas exchange to take place.
The immune system is also affected, as mucus buildup in the lungs can lead to an increased risk of respiratory infections. The mucus can trap bacteria and other pathogens, which can then cause infections in the respiratory system. This can lead to inflammation and further narrowing of the airways, making it even more difficult for Jack to breathe.
To add further detail, the mucus buildup in Jack's lungs can lead to a condition known as cystic fibrosis (CF). CF is a genetic disorder that affects the respiratory, digestive, and reproductive systems.
In CF, the body produces thick, sticky mucus that can clog the airways in the lungs, making it difficult to breathe. This mucus can also block the ducts in the pancreas, preventing digestive enzymes from reaching the small intestine and leading to malnutrition.
Therefore, the respiratory and immune systems are the two organ systems primarily affected by Jack's condition.

Explain why a trait inherited by incomplete dominance is not a blend of two alleles.
Answer:
The trait is inherited by incomplete dominance is not a blend of two alleles because both are equal and appear on the phenotype therefore it is not a blend of two alleles.
Explanation:
A trait which is inherited by Incomplete dominance is not a blend of two alleles as both the alleles show their effect as both are dominant however not completely but character appears in the phenotype of the person.
What is incomplete dominance?
Incomplete dominance results from the cross in which each of the parent is genetically unique and gives rise to progeny whose phenotype is in between the two parents. Incomplete dominance is also known as semi-dominance and partial dominance.
Incomplete dominance resembles with the idea of blending inheritance of characters, but can still be explained through Mendel's laws with some modifications. The alleles here do not exert full dominance and the offspring produced resembles a mixture of the two phenotypes of parents.

describe the characteristics that fishes have allow them to live and reproduce in water
Fish have adapted to their environment through the evolution of gills, swim bladders and fins. Gills allow fish to absorb oxygen from the water, swim bladders allow fish to maintain an appropriate level of buoyancy and fins allow the fish to move through the water. Different species exhibit specializations of these features to thrive in their own way.
Most fish have swim bladders that are permanently sealed, but other fish have swim bladders that can hold varying amounts of air. Salmon have open swim bladders, and they must gulp air at the surface to keep them full. Some fish, such as sharks, lack swim bladders entirely. This causes them to sink if they do not maintain forward motion.
Fish have fins that are adapted to their lifestyle. Some have evolved into long, barbed structures, suitable for defense. Other fish have fins suited for achieving great speed or for walking along the bottom of the ocean.
Therefore, Fish breathe by drawing water in their mouths and forcing it out of the body via a number of gill slits.

According to the Precambrian rock record, much of Earth’s first free oxygen combined with
Iron
According to the Precambrian rock record, much of Earth’s first free oxygen combined with iron.
Explanation;Oxygen originated from tiny organisms known as cyanobacteria or blue-green algae. These organisms conducted photosynthesis using sunlight, water and carbon dioxide to produce simple sugars and oxygen.Initially, the oxygen produced, quickly combined with elements in Earth's crust, primarily Iron removing oxygen from the atmospheres. After the supply of oxidizable surfaces ran out, oxygen began to accumulate in the atmosphere and the modern high-oxygen rich atmosphere would have developed.Chains of nucleic acids have directionality and are read in a certain way just like languages are read from "left to right" or "right to left."
DNA is always read in the_______direction, 3' to 5' or 5' to 3'
whereas RNA is read in the_______direction, 3' to 5' or 5' to 3'
Ans.
During DNA replication, DNA polymerase synthesizes new daughter strand in 5' to 3' direction as it can add new nucleotide molecules at 3'-OH group of growing strand only. During transcription, RNA polymerase also synthesizes RNA molecules in 5' to 3' direction. Thus, the template DNA is always read by DNA polymerase or RNA polymerase in 3' to 5' direction.
During translation, a long polypeptide chain is made by reading information from mRNA molecule. The RNA molecule during protein synthesis is always read in 5' to 3' direction, from start codon to stop codon.
Thus, the correct answer to fill in first blank is 3' to 5' and in second blank is 5' to 3'.

What are two substances that are useful because of their viscosity ?
Oil and liquid soap are the two substances that are useful because of their viscosity.
What is viscosity?Viscosity is the ability of a fluid, liquid, or gas to resist changing its shape or moving nearby areas in relation to one another. Viscosity is a sign of flow resistance. Fluidity, metric indicating ease of flow, is the reciprocal of viscosity. For instance, molasses is more viscous than water.
Viscosity may be considered as internal friction between both the molecules; this friction prevents the formation of velocity disparities within a fluid since a section of a fluid that is compelled to move carries along nearby parts to some extent. When fluids are employed as lubricants and carried in pipes, viscosity has a significant role in defining the forces that must be overcome. In procedures like spraying, injection molding, and surface coating, it regulates the liquid flow.
Therefore, the two substances that are useful because of their viscosity are oil and liquid soap.
