explain how blood flows through the heart
Answer:The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.

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.

Answer the lab question, “What is the effect of the inheritance of one trait on the inheritance of a second trait?” with a hypothesis. Remember that you can either assume that the two genes are independent or that they are linked. What results would you expect in either case?
Answer:
please give me branlist and follow
Explanation:
One hypothesis would be "The inheritance of one trait does not affect the inheritance of another trait". It can be explained with the help of law of independent assortment. It states that the genes are randomly distributed in the gametes, that is, independent of each other.

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.

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.

Why does DMD affect mostly boys? Describe the type of inheritance pattern that DMD follows
Answer:
Inheritance in DMD
DMD is inherited in an X-linked pattern because the gene that can carry a DMD-causing mutation is on the X chromosome. Every boy inherits an X chromosome from his mother and a Y chromosome from his father, which is what makes him male. Girls get two X chromosomes, one from each parent.

Which of the following best predicts a long term effect of the differences between the E and Z strains
Answer:The difference between the forms of the sex pheromone 11−TDA produced by E and Z strains will act as a prezygotic reproductive barrier leading to sympatric speciation.
Explanation:The difference between the forms of the sex pheromone 11−TDA produced by E and Z strains will act as a prezygotic reproductive barrier leading to sympatric speciation.
Conducting long-term studies to observe the effects of E and Z strains would best predict the long-term effects of their differences.
What are E and Z strains?In biology, E and Z strains are used to describe different genetic variants or subpopulations of a species. These designations are often used in studies of insects, particularly in the context of reproductive isolation and speciation.
For example, in some species of moths, E and Z strains are distinguished based on differences in the production of sex pheromones. Females of each strain produce different forms of the pheromone, which may act as a barrier to mating between individuals of different strains. Over time, this could lead to the development of distinct populations that are reproductively isolated from each other, potentially leading to the formation of new species. Other factors, such as geographic isolation and genetic drift, may also contribute to speciation in these and other organisms.

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.
