umka21 [38]

To make the quadriceps perform more work and increase the efficiency of the exercise, Sean should minimize the amount of trunk flexion at the start of the concentric phase.

We can describe trunk flexion as forward pelvic tilt and flexion of the spine. This activity causes more pressure on the muscles of your quadriceps and hence helps in building them.

The quadriceps can be described as the muscles that are present in the front region of the thigh. These area has more muscle mass as compared to other areas of your brain and hence need to be worked on so that the muscle mass here can be reduced.

The correct answer is "increased activity of the right hippocampal formation".
Hippocampus is a brain area which is part of the limbic system and is located below the cerebral cortex. Humans have two hippocampi, one in each side of the brain. Hippocampus is responsible for the formation of long-term memories, by participating in the consolidation of short-term to long-term memory. It also plays a very important role in spatial memory and orientation.
The task that this experienced cab-driver is asked to perform is related to spatial navigation and orientation abilities. The right hippocampus has been shown to participate in the formation of memory for locations in specific environments, while the left hippocampus has been shown to be involved in autobiographical and episodic memory. As a result, the PET scan will show an increased activity of the right hippocampus.

1. List 2 interactions between the earth spheres and the water cycle.
Harrizon [31]

Answer:

The carbon cycle, as the nitrogen cycle, occurs in all the spheres: Biosphere, Atmosphere, Geosphere and Hydrosphere.

Explanation:

Most Earth events involve interaction between multiple spheres. For example, rain is the movement of water (the hydrosphere) from the atmosphere to the lithosphere where it collects in lakes, rivers, or streams. Water is an important resource for inhabitants of the biosphere.

The Atmosphere-contains all the air in Earth's system. The upper portion of the atmosphere protects the organisms of the biosphere from the sun's ultraviolet radiation. It also absorbs and emits heat. This sphere is also where weather occurs.

The nitrogen cycle occurs in all the spheres and ecosystems. It passes through rocks, water, atmosphere, plants, etc.

In atmosphere and biosphere: Nitrogen is about 78% of the gases in the atmosphere an it’s a essential component of the living organisms. It enters plants through the microorganisms that convert this nitrogen into ammonia. After this conversion, the plants absorb this substance. It can pass to animals when they eat these plants. Then, when they urinate, bacteria convert ammonia to nitrogen again and it returns to the atmosphere.
