In ecosystem, Killer whales are apex predators, which means they have no natural predators.

An apex predator, also known as a top predator, is a predator at the top of a food chain, without natural predators of its own. Apex predators are usually defined in terms of trophic dynamics, meaning that they occupy the highest trophic levels.

In the natural sciences, an apex predator is a predator that exists at the very top of the food chain. Unlike some other predators, it's never preyed upon itself. Examples include polar bears, lions, crocodiles, and orcas.

There are some “apex” predators that are found throughout much of the world, including grey wolves, blue whales, killer whales and great white sharks. In my mind, however, humans are clearly the overall apex predator of the world. We've even been called the super-predator.

In general, the mass of the heavier planets is higher. In general, the denser planets have higher densities. A planet's surface gravity increases as a planet's mass increases.

The density of water is 1.0 g/cm3. Saturn is the only planet that would float if there was a large enough tub of water. The other planets would all float away. Mars and Mercury are the only two worlds where you would weigh less than you do on Earth.

You would be heavier than you are on Earth on the other worlds. This is due to the fact that each planet's mass and gravity are measured in relation to Earth, which is why Earth is assigned a value of 1.

In the context of cardiorespiratory endurance, two field tests commonly discussed are the 1-mile (1.6 km) walk test and the 1.5-mile (2.4 km) run test. These tests assess an individual's aerobic fitness and provide an estimation of their cardiovascular and respiratory endurance.

1-Mile Walk Test: In this test, the participant is required to walk one mile (1.6 km) as quickly as possible. The time taken to complete the walk is recorded, and it is typically performed on a flat surface or track. The test is suitable for individuals of various fitness levels and ages, making it widely accessible. It is often used as a preliminary assessment for sedentary individuals or those starting an exercise program.

1.5-Mile Run Test: The 1.5-mile (2.4 km) run test is a more challenging endurance test. Participants are required to run a distance of 1.5 miles (2.4 km) as fast as they can. This test is commonly used by military organizations, law enforcement agencies, and athletic programs to assess the cardiovascular fitness and endurance of individuals. The time taken to complete the run is recorded and used to evaluate cardiorespiratory fitness levels.

Both field tests provide a practical and convenient way to assess cardiorespiratory endurance without the need for specialized equipment or laboratory settings. They are valuable tools for evaluating an individual's aerobic capacity and can be used to monitor progress and set fitness goals.

The bone that does not belong to the appendicular skeleton is the sternum.

The human skeleton is divided into two main parts: the axial skeleton and the appendicular skeleton. The axial skeleton includes the bones of the skull, vertebral column, and ribcage, while the appendicular skeleton consists of the bones of the limbs and the girdles that attach the limbs to the axial skeleton.

The bones listed below all belong to the appendicular skeleton:

Humerus: This is the bone of the upper arm, extending from the shoulder joint to the elbow joint.

Femur: This is the thigh bone, the largest and strongest bone in the body, extending from the hip joint to the knee joint.

Ulna: This is one of the two bones of the forearm, located on the inner side of the arm.

Radius: This is the other bone of the forearm, located on the outer side of the arm.

Tibia: This is the larger of the two bones in the lower leg, commonly known as the shinbone.

Fibula: This is the smaller bone in the lower leg, located on the outer side.

Conclusion: The sternum is not part of the appendicular skeleton. It is a flat bone located in the center of the chest and is considered part of the axial skeleton, along with the skull, vertebral column, and ribcage.

1. The plot without Rudbeckia has H = 1.86, while the plot with Rudbeckia has H = 1.88. Also, the plot with Rudbeckia has higher species richness and slightly higher species diversity than the plot without Rudbeckia.

2. By adding Rudbeckia to the plot increased species richness by 1 and species diversity (H) by 0.02.

1. To calculate species richness and diversity:
- Species richness: Count the number of species in each plot. The plot without Rudbeckia has 9 species (A, B, C, D, E, F, G, H, I), while the plot with Rudbeckia has 10 species (A, B, C, D, E, F, G, H, I, J).
- Shannon diversity index (H): Use the formula H = - Σ(pi * ln(pi)), where pi is the proportion of each species in the plot. The plot without Rudbeckia has H = 1.86, while the plot with Rudbeckia has H = 1.88.

So, the plot with Rudbeckia has higher species richness and slightly higher species diversity than the plot without Rudbeckia.

2. To calculate the change in species richness and diversity:
- Change in species richness: 10 - 9 = 1
- Change in species diversity (H): 1.88 - 1.86 = 0.02

So, adding Rudbeckia to the plot increased species richness by 1 and species diversity (H) by 0.02.

During glycolysis, the electron carrier NAD+ accepts a pair of high-energy electrons and becomes NADH.

Glycolysis is the first stage of cellular respiration, during which glucose is broken down into two molecules of pyruvate. In this process, the electron carrier NAD+ plays a crucial role by accepting a pair of high-energy electrons, which are released when glucose is broken down.

When NAD+ gains these electrons, it is reduced to form NADH. This conversion allows the cell to store energy from glucose in the form of NADH, which can then be used to produce ATP in later stages of cellular respiration. The production of NADH is an essential step for cells to harness the energy stored in glucose efficiently.
