Answer: The cardiovascular System
Explanation:
The cardiovascular system homes the heart. The heart is a pump that circulates oxygen and blood throught your body essentially keeping you alive. Without the heart your brain would be dead because your brain would not be getting enough oxygen to funtion. So, although the brain and spinal cord are very important the heart is also if not more for it is the only way you live. You can be brain dead and still alive but not heart stopped and alive.
I hope this helps!

What causes air masses to move?
When prevailing westerlies shift directions and move toward the west.
Weather conditions change rapidly to produce storms.
A collision takes place between two natural wind patterns.
Long, narrow bands of wind blow in the upper atmosphere.
Answer:-The cause of the air masses to move is: The current of air and wind causes the air masses to move. The change in the air masses is the reason for the change in the weather.
Explanation:
Air masses are moved by differences in air pressure, which is caused by uneven heating of the earth's surface by the sun. This creates areas of high and low pressure, and air masses will move from areas of high pressure to areas of low pressure.
What is air mass ?An air mass is a large body of air in the atmosphere that has similar temperature and humidity characteristics throughout its horizontal extent.
Air masses are classified based on their source region, which can be over land or water and in different latitudes. As air masses move from their source regions, they can bring changes in weather conditions to the areas they move over.
The movement of air masses can also be influenced by the rotation of the earth, which causes the Coriolis effect. This effect causes air masses in the Northern Hemisphere to be deflected to the right, and air masses in the Southern Hemisphere to be deflected to the left.
The collision of two air masses with different properties, such as temperature and humidity, can also cause movement and create weather conditions.

Which of these organisms is not a chordate? earthworm snake sea squirt human
Answer:
Humans
Explanation:
Humans are not chordates because humans do not have a tail. Vertebrates do not have a notochord at any point in their development; instead, they have a vertebral column.
The organism that is not a chordate is the earthworm.
What are chordates?Chordates are a group of animals that possess four distinctive anatomical features at some point during their life cycle: a notochord, dorsal nerve cord, pharyngeal slits, and a post-tail. These features set chordates apart from other animal groups and have been critical in their evolutionary success.
Chordates include a wide variety of animals, ranging from fish, amphibians, and reptiles to birds and mammals, including humans. Chordates are found in aquatic environments such as oceans, rivers, and lakes, as well as on land, and play a critical role in many ecosystems as both predator and prey.

Answer:
wheat,oatmeal,barley
Explanation:
Examples of Complex Carbs
Whole grains such as brown rice, wild rice, oatmeal, and whole-grain (rather than pearled) barley.
Grain-like foods such as quinoa (a seed) and buckwheat (a grass)
Starchy vegetables including potatoes, sweet potatoes, and corn.
The carbohydrates are defined as the main suppliers of energy to the body. Most of the carbohydrates come from the complex carbohydrates and natural sugars. Wheat, barley and oatmeal are examples of the complex carbohydrates.
What are complex carbohydrates?The carbohydrates are the macronutrients by which our body obtains the energy. They are called carbohydrates as they contain carbon, hydrogen and oxygen. The complex carbohydrates are made up of sugar molecules which are strung together in long, complex chains.
The complex carbohydrates are found in foods such as peas, beans, whole grains and vegetables. Both the simple and complex carbohydrates are turned to glucose in the body and are used as energy.
Here among the given examples, the complex carbohydrates are Wheat, barley and oatmeal and others are simple carbohydrates. The brown rice, oats, wild rice, starch etc. are also complex carbohydrates.

Identify each wave interaction based on how it changes direction.
The wave changes direction as it bends and scatters.
The wave changes direction as it changes its speed.
The wave changes direction at an angle equal to the angle of incidence.
The wave changes direction as it bends and scatters. - Refraction because it changes in direction of the waves that occur when waves travel from one medium to another.
The wave changes direction as it changes its speed. - Refraction because the waves change speed when they pass across the boundary between two different substances, such as the light waves refracting when they pass the air to glass.
The wave changes direction at an angle equal to the angle of incidence. -reflection because if a wave hits a mirror at an angel of 36, and it will be reflected at the same angel of 36.
Explanation: Hope this helps, Have a good day!
The wave changes direction as it bends and scatters is known as reflection, the wave changes direction as it changes its speed is known as refraction, and the wave changes direction at an angle equal to the angle of incidence is diffraction.
What are wave interactions?When waves interact, they can change direction in different ways. Here are the three ways that waves can change direction:
1. Reflection: The wave changes direction at an angle equal to the angle of incidence. This happens when a wave hits a barrier or a surface that it can't pass through. The angle of incidence is the angle between the incoming wave and the normal, which is an imaginary line perpendicular to the surface.
2. Refraction: The wave changes direction as it changes its speed. This happens when a wave passes from one medium to another, and the speed of the wave changes. When this happens, the wave bends towards or away from the normal, depending on the direction of the change in speed.
3. Diffraction: The wave changes direction as it bends and scatters. This happens when a wave encounters an obstacle or a gap in a barrier that is comparable in size to the wavelength of the wave. When this happens, the wave bends around the obstacle or spreads out through the gap.

The one-way flow of energy through the biosphere is made possible through photosynthesis. Plants convert solar energy into sugars, which they use to power themselves and other organisms. Carbon and oxygen nutrients are also cycled through the biosphere as a result of photosynthesis.
