Final answer:
Organ systems are like a sports team or an orchestra where each player or instrument, respectively, plays a specific role, but they all need to work together harmoniously for the success of the team or the creation of a symphony.
Explanation:
An organ system is a group of organs that work closely together to perform the functions needed for the body to function properly. One analogy to describe how organ systems work together is comparing them to a sports team. Every player or organ has a specific role, but they must work in concert to win a game or keep the body healthy. Another comparison is that of an orchestra, where different instruments or organs each play their own part, but collectively they create a symphony or maintain body health.
Examples of Organ Systems
The nervous system, which includes the brain, spinal cord, and nerves, coordinates the body's activities by receiving and sending information.
It is essential that these organ systems work together synergistically to ensure the organism's survival, much like how individual team members or musicians must collaborate to achieve their shared goal.

1) What characteristics increase the likelihood that a nonnative species will become an invasive species?
2) What conditions in an ecosystem are likely to allow a species to become invasive there?
3) Biological control involves the introduction of a natural enemy to control the spread of an organism that is considered a
pest. What are the trade-offs in introducing a nonnative species to control an established invasive species?
1. The non-native species are considered to be invasive only when they cause harm. Some of the features that increase the possibility of a non-native species in becoming an invasive species are they reproduce easily, they are habitat generalist, they out-competes other plant species, possesses the tendency to produce abundant seeds, and are not influenced by the native diseases and pests.
2. If an ecosystem were identical to the local ecosystem of a species, it would possibly be easier for the species to invade. For example, if the species is found in a novel location, which is the identical biome as its local ecosystem, then it is probably more common to turn into an invasive species.
3. The introduction of a non-native species to monitor the invasive species does not always work. However, even if it works, the other native species could also get influenced adversely. If the population of the introduced species enhances too much, it can result in competition for space and food with the native species. The non-native species may also result in the introduction of diseases, which might kill or harm the local species.
Nonnative species with characteristics like rapid reproduction and a lack of predators are more likely to become invasive. Human-disturbed ecosystems are more susceptible to invasions. Biological control carries risks, emphasizing the importance of careful research and risk assessment.
Characteristics that increase the likelihood that a nonnative species will become an invasive species include early reproduction, rapid reproduction, lack of predators in the new environment, ease of dispersion, and the ability to thrive in various ecosystems. When these characteristics are met in ecosystems that have been disturbed by human activity or lack the biological controls of the species' native range, a nonnative species may become invasive.
Biological control involves the intentional introduction of a natural enemy to manage invasive species. The trade-offs include the potential of the biocontrol agent to become invasive itself and cause harm to native species. This underscores the need for thorough research and risk assessment before implementing biological control measures.

Distinguish among hypertonic hypotonic and isotonic solutions
Hypertonic:Cell has lost all of the solute
Hypotonic: Cell is overfilled and is ready to burst
Isotonic: Cell is at a homeostasis condition
Final answer:
Hypertonic solutions have a higher solute concentration than the cell, leading to water leaving the cell. Hypotonic solutions have a lower solute concentration, causing water to enter the cell. Isotonic solutions have equal solute concentrations, which lead to no net water movement across the cell membrane.
Explanation:
Distinguishing Hypertonic, Hypotonic, and Isotonic Solutions
Cells encounter different environments which can impact their function based on the concentration of solutes outside of them. Three terms-hypertonic, hypotonic, and isotonic-describe the relationship between the external solution's solute concentration and that within the cell's cytoplasm.
Hypertonic solutions have a higher solute concentration compared to the cytoplasm. This causes water to leave the cell, potentially leading to the cell shriveling up.Hypotonic solutions have a lower solute concentration than the cell's cytoplasm. Water will enter the cell, which can result in the cell swelling or even bursting.Isotonic solutions have the same solute concentration as the cell's cytoplasm. In this scenario, there is no net movement of water into or out of the cell although water molecules continue to exchange across the cell membrane.Understanding these osmotic conditions is crucial, especially in healthcare, where intravenous solutions must be isotonic to prevent damage to blood cells.
Trace the path of a drop of venous blood from the left ankle to the right side of the brain.
Venous blood from the ankle travels and goes through tibial vein, popliteal vein, femoral vein, external iliac vein, common iliac vein, inferior vena cava to the heart (right side). From the heart to the right side of the brain, blood goes through the aorta and the brachiocephalic artery. The brachiocephalic artery the then divides into the right common carotid artery and the right subclavian artery and both supply the right side of the brain.
The path of a drop of venous blood from the left ankle to the right side of the brain is as follows:
Inferior vena cava brings blood from the abdomen and leg area including ankle to heart. Then from heart blood goes through left atrioventricular valve left ventricle aortic semilunar valve, aorta, brachiocephalic trunk, right common carotid artery, right internal carotid artery, circle of willis capillary bed of frontal lobe, transverse sinus, right side of the brain. In this way, venous blood goes from left ankle to the right side of the brain.A red blood cell will shrink in size when placed in a more concentrated salt solution because of the passive process called
Answer:
Osmosis
Explanation:
In a highly concentrated salt solution, concentration of water is comparatively lower than the fluid inside red blood cells. This develops a concentration gradient.
Due to this difference in concentration, the water starts flowing out of the red blood cells across its permeable layer. Due to this movement of water, red blood cell shrinks. This physical phenomenon in which a substance move from a region of high concentration to a region with lower concentration across any permeable membrane is called Osmosis.

The phytoplankton at the bottom of the pyramid take in and store a certain amount of the suns energy. Does all of the energy stored by the phytoplankton reach the top level of the pyramid?
Answer:
Phytoplanktons are single celled organisms found in aquatic ecosystems. They make their own food by capturing sunlight for photosynthesis. Example of some phytoplanktons are diatoms, dinoflagellates and cynobacteria ( blue green algae). Phytoplanktons functions as the primary producers of the aquatic ecosystem. They attain the bottom level in the energy pyramid and store certain amount of suns energy and convert it into food. The energy derive from food is transferred to higher energy levels in the energy pyramid as phytoplanktons are eaten up by many aquatic animals. Therefore, the energy transferred from phytoplankton to higher energy levels gets decreased according to 10% law which says, energy decreases 10% at each higher trophic level. So, all the energy stored by the phytoplankton will not reach the top level of the pyramid.
Answer:
No, because some of the energy is lost to the environment as heat as it is transferred between organisms.
Explanation:
Large bodies of water, such as lakes and oceans do not quickly fluctuate (change) in temperature. What is the reason for this phenomenon? Water is a versatile solvent due to its polarity Water doesn’t change temperature because is an acid. Water moderates temperature due to its high heat capacity Water acts as a buffer for concentration of chemical, which affect temperature.
C; Water moderates temperature due to its high heat capacity.
Large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature because water has a high heat capacity and requires a large amount of energy to change its temperature. This property of water allows it to stabilize temperatures, resulting in milder climates near large bodies of water.
Explanation:The reason that large bodies of water, such as lakes and oceans, do not quickly fluctuate in temperature is because water has a high heat capacity and requires a large amount of energy to change its temperature. This means that it takes a long time for water to heat up or cool down. For example, water can absorb a tremendous amount of energy with very little resulting temperature change. This property of water allows it to stabilize temperatures, which is why climates closer to large bodies of water are generally milder than landlocked climates.
