Answer:
Copy number variations (CNVs)
Explanation:
Copy number variations (CNV) are variations in the number of copies of specific nucleotide sequences present in the genome of organisms of the same species (or closely related species). The Human Genome Project showed that the human genome contains many CNVs, which are caused by duplications and deletions (indels) of large regions of repetitive (non-coding) DNA regions. Since CNV are usually localized in non-coding DNA regions, they generally are evolutionary neutral (i.e., prone to diverge among organisms) and therefore don't affect the phenotype of the individual. Single Nucleotide Polymorphisms (SNPs) represent another type of sequence variation that is abundant across the human genome.
Does the carbon cycle in this diagram appear to be in balance or out of balance? Use specific evidence from the diagram to support your answer. This diagram shows gigatons of carbon moving to and from the atmosphere each year.
This diagram shows gigatons of carbon moving to and from the atmosphere each year and yes the diagram is valences.
Which factor is responsible for fixation?Cutting down large areas of forests Plants are responsible for fixation of atmospheric carbon dioxide. If the number of plants is reduced, the amount of carbon dioxide moved from the atmosphere to vegetation will also decrease.
The biogeochemical cycle in which carbon is exchanged between the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth is known as the carbon cycle.
According to the question, emitted amount of carbon is 480 gigatons but the amount of carbon in the environment is approx 190 gigatons, so the remaining amount of the carbon was stoored by the oceans and other water reservoir, which may be get clear throug the attached diagram.
Therefore, This diagram shows gigatons of carbon moving to and from the atmosphere each year and yes the diagram is valences.

If you had to prioritize the removal of plants from an area , rank the following in order of highest to lowest priority by dragging them in the correct order top to bottom .
native non - aggressive
non - native non - aggressive
non -native aggressive
native aggressive
Answer:
non -native aggressive
non - native non - aggressive
native aggressive
native non - aggressive
Explanation:
Non native plants are always the worst for the area, so they go first, followed by native and aggressive plants.
Plants are living organisms, which are found in different regions. The plants can be native to a given area, can be non-native, or aggressive.
The correct sequence is:
non -native aggressive
non - native non - aggressive
native aggressive
native non - aggressive
The plant species can be described as:
Non-native species of plants are described as the plants that cause economic and ecological losses in a given area. These plants are the worst and can hamper the natural ecosystem of the given location. Native species are defined as organisms that have occurred naturally in a particular location or habitat. These species are great for a given ecological location and maintain a stable ecosystem.
Aggressive species or invasive species are defined as the species that occupy the natural habitat of organisms very fast. these species are unwanted and can negatively affect an ecosystem.
Thus, the native, non-native, and invasive species are different types of organisms that can either benefit or harm the ecosystem.

In 1906, President Theodore Roosevelt created the Grand Canyon National Game Preserve on the Kaibab Plateau in northern Arizona. Between 1907 and 1923, cattle grazing was greatly reduced, mule deer hunting was eliminated, and predators were killed. Over 800 cougars, 20 wolves (most had already been killed in the 1800s), and 7000 coyotes were trapped or shot. In response, the mule deer herd began to increase: By 1915, deer numbers were estimated at 25,000; 50,000 by 1920; and 100,000 by 1923. The removal of the livestock and predators, and the cessation of hunting in 1907 ________. decreased the carrying capacity for the Kaibab deer decreased r, allowing more births among Kaibab deer decreased K, allowing more births among Kaibab deer removed the limits on immigration, allowing more deer into the area increased the carrying capacity for the Kaibab deer
Answer: increased the carrying capacity for the Kaibab deer
Explanation: The removal of livestock means more food as grass is available for the Kaibab deer to feed on. In the same vein, the nonexistence of predators would allow for proliferated growth which in turn would increase the number of deer population on the plateau. What this means is that the Preserve is now able to carry as much deer population as it could going forward thereby increasing the carrying capacity for the Kaibab deer which was evident by the increasing figures on the years the deer numbers were estimated.

7. What is the correct order of the levels of organization in the human body from
the simplest to the most complex?
Answer:
The major levels of organization in the body, from the simplest to the most complex are: atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism.
All living and non-living things are made of one or more unique substances called elements, the smallest unit of which is the atom, (for example, the element oxygen (O) is made of O atoms, carbon (C) is made of C atoms and hydrogen (H) is made of H atoms. Atoms combine to form molecules.
All living structures are made of cells, which are made of many different molecules. Cells are the smallest independent living thing in the human body. The body is made of many different cell types, each with a particular function, (for example muscle cells contract to move something, and red blood cells carry oxygen). All human cells are made of a cell membrane (thin outer layer) that encloses a jelly-like cellular fluid containing tiny organ-like structures called organelles.
A tissue is a group of similar cells that work together to perform a specific function. There are four main tissue types in humans (muscular, epithelial, nervous and connective). An organ is an identifiable structure of the body composed of two or more tissues types (for example, the stomach contains muscular tissue made of muscle cells, which allows it to change its shape, epithelial tissue which lines both the inner and outer surface of the
stomach, nervous tissue which sends and receives signals to and from the stomach and the central nervous system, and connective tissue which binds everything together).
Organs often perform a specific physiological function (for example, the stomach helps digest food). An organ system is a group of organs that work together to perform a specific function (for example, the stomach, small and large intestines are all organs of the digestive system, that work together to digest foodstuff, move nutrients into the blood and get rid of waste). The most complex level of organization, the human organism is composed of many organ systems that work together to perform the functions of an independent individual.
