Answer:
Specialized cells, organ systems, and cell organelles are all present in multicellular but not unicellular organisms
Explanation:
A. Specialized cells and B. Organ systems are features that are present in multicellular organisms but not in unicellular organisms.
Specialized cells are cells that have developed unique structures and functions to perform specific tasks within the organism. In multicellular organisms, different types of specialized cells come together to form tissues, which in turn form organs and organ systems.
Organ systems are groups of organs that work together to perform specific functions within the organism. For example, the digestive system, respiratory system, and circulatory system are all examples of organ systems that are present in multicellular organisms but not in unicellular organisms.
Cell division (C) and cell organelles (D) are features that are present in both unicellular and multicellular organisms. Cell division is necessary for both types of organisms to reproduce, while cell organelles are structures that are present within cells to perform specific functions.

The founding number of individuals of a species can be small on an island
Reproductive rates tend to be lower on islands
Species are isolated in an island
Islands have a high rate of species exchange
The founding number of individuals of a species can be small on an island, which leads to low genetic diversity, therefore, any genetic change that occurs will have a more pronounced effect on the population is the correct option.
Islands have a high rate of species exchange, this is not correct, because the isolation of species is a key factor in the divergence and fixation of traits .The following explain why trait divergence and fixation can occur more quickly on islands than in other geographical locations: A species' initial population on an island may be small. On islands, reproductive rates are lower. Species are isolated in an island .Reproductive rates tend to be lower on islands, which means that any genetic changes that occur will be passed on to fewer offspring and will therefore have a greater chance of becoming fixed in the population. Species are isolated in an island, meaning that there is less gene flow between different populations, which allows genetic changes to accumulate and become fixed in the population more easily.Islands have a high rate of species exchange, this is not correct, because isolation of species is a key factor in divergence and fixation of traits.

People in the northeast united states thought that Warblers were an exception to goss competitive exclusion principle because
The Competitive Exclusion Principle was first proposed by G. F. Gause in 1934 and stated that two species cannot coexist indefinitely in a habitat if they have the same ecological niche, or if they use the same resources in the same way. This means that one species will eventually outcompete the other and drive it to extinction.
Warblers are a group of small songbirds that are found in a wide range of habitats throughout the northern hemisphere. They are known to have a high degree of ecological niche partitioning, which means that they have evolved to use different resources within their habitat, allowing them to coexist without competing.
For example, some warbler species feed on insects found on leaves while others feed on insects found on branches, some species prefer to forage in the canopy while others in the understory and some species prefer to forage in conifers while others in deciduous trees. This high degree of niche partitioning allows warblers to coexist in the same habitat without competition for resources.
Additionally, Warblers also have some morphological adaptations such as bill shape, size, and foraging behavior, which help them to exploit different resources in their habitat.
In summary, Warblers are known to have a high degree of ecological niche partitioning, which allows them to coexist without competing with each other, this is why people in the northeastern United States may have thought that Warblers were an exception to Gause's competitive exclusion principle.

Anchorage regulates cell division by regulating a cell's attachment to a surface, which has an impact on the cell's capacity to divide. Cell density regulates cell division by alerting cells when their immediate environment becomes overcrowded, prompting them to cease dividing or go through apoptosis. Internal regulatory proteins that regulate the cell cycle's progression through its several stages include cyclins and kinases.
Hormones and other external growth factors can also regulate cell division by signalling to cells to start or stop cell division .

Draw an example carbon cycle, showing the atmosphere and at least 3 other major sinks/reservoirs Include biotic and abiotic components in your diagram. Show how carbon flows to and from all four of these locations, labeling the process that connects each. Include one example of how humans are connected to the carbon cycle.
The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, oceans, and living organisms.
The atmosphere is a major reservoir of carbon in the form of carbon dioxide (CO2). The biotic components of the carbon cycle in the atmosphere include plants and algae, which absorb CO2 during photosynthesis to produce oxygen and organic compounds.
The oceans are another major reservoir of carbon, mostly in the form of dissolved CO2, bicarbonate ions, and carbonate minerals. The biotic components of the carbon cycle in the oceans include phytoplankton, which absorb CO2 during photosynthesis and transfer it to the ocean food web.
The land is another major reservoir of carbon, mostly in the form of soil organic matter, dead plant matter, and fossil fuels. The biotic components of the carbon cycle on land include plants, which absorb CO2 during photosynthesis, and decomposers, which break down dead plant matter and transfer carbon to the soil.
The process of photosynthesis and respiration connect the atmosphere, land and oceans. During photosynthesis, plants and algae absorb CO2 from the atmosphere, convert it into organic compounds, and release oxygen. During respiration, plants, algae, and other organisms use these organic compounds to produce energy, releasing CO2 back into the atmosphere.
Humans are connected to the carbon cycle in many ways. For example, the burning of fossil fuels, deforestation, and land use change all release large amounts of carbon into the atmosphere. These activities contribute to the increase of CO2 in the atmosphere which causes climate change.
In summary, the carbon cycle is the exchange of carbon between the atmosphere, land, oceans, and living organisms. The biotic and abiotic components of the carbon cycle are connected by the process of photosynthesis and respiration. Human activities such as burning fossil fuels, deforestation and land use change have significant impact on the carbon cycle and the increase of CO2 in the atmosphere.

These PfEMP1 variations bind to endothelial cells and are found in the RBC plasma membrane. According to the passage, across several mitotic generations, only one var gene is transcribed at a time, however during an infection, the var gene that is expressed changes over time.

The compound used to move the reducing equivalents of cytosolic NADH into the mitochondria is malate.
What is compound?Compound is a substance made up of two or more elements chemically combined in a fixed proportion. Compounds are different from mixtures, which are made up of two or more elements, compounds, or other substances that are not chemically combined and can be separated by physical means. Examples of compounds include water (H2O), salt (NaCl), and carbon dioxide (CO2). Compounds are held together by chemical bonds, which are the attractive forces between atoms and molecules.
The malate-aspartate shuttle is a mechanism whereby NADH is oxidized in the cytosol to NAD+. Malate is then formed and transported into the mitochondria, where it is oxidized to oxaloacetate. This process yields NADH in the mitochondria, allowing the NADH to be used in the electron transport chain.
