Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.

I would say "A"

Answer:

Sight and vision are important because they allow us to connect with our surroundings, keep us safe, and help maintain the sharpness of our minds. Sight and vision are different entities. Sight is physical – it is a sensory experience in which light reflects off of shapes and objects and the eyes then focus this light.

Answer:

Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.

Explanation:

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.

Answer:

Our immune system produces antibodies.

Explanation:

Injecting an  antigen from a pathogen would help our immune system memorize the infection and protect our body from causing of the disease because our immune system produces antibodies against that antigen so when the pathogen enters our body these antibodies attack on that and prevent them of causing infection in the body so that's why injecting an  antigen has to be done from the childhood to prevent diseases.

Explanation: D. Arenchyma​

Answer:

Due to the high pressure arteries hold and it is difficult to control.

Explanation:

Consider most of the arteries (minus the pulmonary arteries) have a thicker layer (lumen) that basically  resists the ejection of blood from the heart. Arteries hold oxygenated blood to the vital organs (the heart itself throught he coronary arteries, the brain that needs EXCLUSIVE oxygenated blood, and lungs). Contrasted to a bleeding vein, bleeding from an artery tends to go faster, which increases the risk of hemorrhage and death.

if you need an analogy, think of it with a hose:  if you take the hose and sever it after it's pumped into the hose on ground level, but the pump is still pumping the water, it will no longer be evenly distributed and spill everywhere.

Answer:

318,6 ms-1

Explanation:

Como sabemos que la relación entre la velocidad del sonido en el aire y la temperatura viene dada por;

V = 331√T / 273

Dónde;

V = velocidad del sonido

T = temperatura en kelvin = (-20) + 273 = 253 K

V = 331√253 / 273

V = 318,6 ms-1
