Why did some people think that there was evidence of intelligent life on Mars?
Answer:
Recent missions to Mars haven't turned up definite proof of life, but some tantalizing possibilities have been uncovered.
Explanation: Water and ice caps if there's water there's life. but its not entirely true... because there isn't any life on mars... or so NASA says National Aeronautics and Space Administration more like Never a straight answer.
Many people believed that there was evidence of intelligent life on Mars, because of the similarities of this planet to planet Earth and because there are indications that there was water on Mars.
Although it is currently known that there is no intelligent life on Mars, many researchers believe that this planet has been inhabited in the past.
There is some evidence that allows this speculation to be established. Among this evidence, scientists claim that:
Mars has some characteristics similar to planet Earth.Many rocks on Mars have organic molecules.There is evidence that the surface of Mars once had water about two thousand years ago.There is water at the poles of Mars.There are water flows on the planet's hot slopes that are resistant to freezing.With this, we can see that, according to the evidence, it is not possible to affirm that there was already intelligent life on Mars, but that the planet has the possibility of having been populated by microorganisms.

Which do scientists link to increased hurricane strength?
O A. Higher ocean temperatures in the arctic
B. Higher land temperatures in the arctic
C. Higher ocean temperatures in the tropics
O D. Higher land temperatures in the tropics
Answer:
Higher ocean temperatures in the tropics
Explanation:
apex :)
Higher ocean temperatures in the tropics are linked to increased hurricane strength. Therefore, option (C) is correct.
What is hurricane strength?Hurricane strength is a measure of the intensity of a tropical cyclone, which is a rotating storm system that forms over warm ocean waters in the tropics. The strength of a hurricane is measured using the Saffir-Simpson Hurricane Wind Scale, which ranks hurricanes from Category 1 (weakest) to Category 5 (strongest) based on their sustained wind speeds.
Hurricanes can cause significant damage due to their strong winds, heavy rainfall, storm surges, and flooding. The strength of a hurricane is influenced by a variety of factors, including warm ocean temperatures, low wind shear, and high humidity. As global temperatures continue to rise due to climate change, it is expected that hurricanes will become more frequent and more intense, which could have significant impacts on coastal communities and infrastructure.

The broken bone begins to take the shape it had prior to the fracture.
A mass of tissue containing cells that produce collagen fibers forms. These collagen fibers extend across the broken bone and attach the pieces back together.
A hematoma forms at the fractured area.
Osteoblasts and osteoclasts arrive at the fracture and begin to produce bone tissue there.
Answer:
The correct order is:
1. A hematoma forms at the fractured area.2. A mass of tissue containing cells that produce collagen fibers forms. These collagen fibers extend across the broken bone and attach the pieces back together.3. Osteoblasts and osteoclasts arrive at the fracture and begin to produce bone tissue there.4. The broken bone begins to take the shape it had prior to the fracture.Explanation:
After the fracture of a bone several events occur that involve the regeneration and remodeling of the broken bone:
Hematoma in the fracture area is produced by the bleeding of the bone marrow, especially when it occurs in long bones. The collagen fibers are intended to initiate the repair process, trying to join the bone fragments that have separated. The purpose of this is to build a soft tissue base on which the new bone will grow. Osteoblasts and osteoclasts are responsible for the process of ossification and remodeling, respectively. Only a bone scar will remain at the fracture site. With the process of ossification and remodeling, the bone acquires the same shape it had before the injury.This whole process is necessary for the morphological and functional recovery of a bone when it has suffered a fracture.
Answer: 4, 2, 1 , 3 is the order on Edge.
( in case they list it different 1-4 is below)
Explanation: ( in sequence)
1.) A hematoma forms at the fractured area.
2.) A mass of tissue containing cells that produce collagen fibers forms. These collagen fibers extend across the broken bone and attach the pieces back together.
3.) Osteoblasts and osteoclasts arrive at the fracture and begin to produce bone tissue there.

5. Consider two soil samples, one from a tropical rain forest and the other from a temperate
deciduous forest Predict which sample would have a greater concentration of organic
material Explain your answer
Answer:
Temperate deciduous forest
Explanation:
The temperate deciduous forest will have more organic matter concentration in it.
Organic matter is a component of biological relics found in the soil. It makes up a significant portion of the soil.
Soil organic matter should not be confused with biomass production. Rainforest due to its biodiversity is rich in organic biomass. These organic matter decays rapidly due to the humid conditions, and are become lost. Also, the rate of weathering in the rainforest is very high. This often washes and removes organic matter from the soil. These conditions are not so in the temperate forest.Which is an example of a trace fossil?
