Hunter-Best [27]2 years ago

Answer:

Darwin's theory of biological evolution tells us that all life on earth may have originated from a single, relatively simple reproducing creature living in the distant past. This idea is based on many observations, one of which is that when living things reproduce, children are often born with random new traits.

Muscles can only contract and relax. How is it possible for you to move in so many different ways? How do muscles allow for loco
MrRa [10]

Explanation:

Muscles act on joints antagonistically. Some muscles will contract while other contract pulling on bones around joint hence enabling movement. An example is the elbow joint is moved by antagonistic action of biceps and triceps. When your biceps contract and triceps relax you are able to bend your arm at your elbow. When your triceps contract and biceps relax, your arms straighten.

Two cities are separated by 200 miles. City X has an altitude of 122 meters and City Y has an altitude of 260 meters. Calculate
OleMash [197]

Answer: 0.69 m/ mile.

Explanation:

The altitude gradient between two cities X and Y = \dfrac{\text{Altitude of City Y - Altitude of city X}}{\text{Distance between two cities}}\times100\%

Given: Two cities are separated by 200 miles.

City X has an altitude of 122 meters.

City Y has an altitude of 260 meters.

The altitude gradient between two cities X and Y =

\dfrac{260-122}{200}=0.69\text{m/ mile}

Hence, the altitude gradient between the two cites = 0.69 m/ mile.

Which features do most stratovolcanoes and cinder cone volcanoes have in common?
Sergeu [11.5K]

Answer:

Option (2)

Explanation:

Strato-volcanoes are the steep, conical shaped, formed by the alternative beds of ash and lava. The magma in this type of volcano contains high silica content and are comprised of bubbles. When the gases are released from these bubbles, then a greater force is exerted from the bottom towards the surface. Due to this, they are very explosive and ejects a huge amount of materials during eruption. For example, Mount St. Helens .

Cinder cones are the simplest volcanoes with steep sides. They are made of the materials and semi solidified lava that are ejected from the vents of the volcano. Eruptions are often explosive due to the force exerted by the gas and the molten lava and are accumulated near the vent. For example, Paricutin.

<u>These two types of volcanoes are similar in terms of its eruption that is violent and explosive in nature. In addition to that, they both have steep sides. </u>

Hence, the correct answer is option (2).
