B.The stars’ light is not bright enough to reach Earth immediately.
C.Stars are light-years away from Earth, so light takes time to reach our planet.

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.

Humans and dogs evolved from a common ancestor. Which pieces of evidence would support this? Select two options.
Both of their adult forms look very similar.
They both had a tail as an embryo.
Their arm and leg structure is similar, but may have a different function.
There are fossils of an organism that is half man, half dog in the fossil records.
Both had gill slits when they were born.
Answer:
They both had a tail as an embryo.
Their arm and leg structure is similar but may have a different function.
Explanation:
They both had a tail as an embryo.
Vestigial structures are those body parts that have lost or reduced their original function during the evolution of a species. These vestigial structures might be found in many animals, including human beings. Vestigial structures were plenty functional for common ancestors. But with evolution, they degenerated, stunted, and became rudimentary for some of the new species.
During the first 4 months of embryogenesis, all mammals have a tail at some point in their development. Dogs develop this structure and keep it during their whole lives, but humans lose it with time during embryogenesis. The tail disappears, and its forming vertebras get fussed with each other composing the coccyx, which represents a vestigial structure. This tailbone is the remnant of a missing tail.
In many animals, the function of the tail is to stabilize, equilibrate and mobilize. But in humans, the coccyx, located at the end of the vertebral column, has lost this original function.
Their arm and leg structure is similar but may have a different function.
The fact that whales, humans, and dogs all have the same bones in the same order, but they matured differently in later embryological development, is an example of homologous characters.
Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.
These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.
These homologous characters are common in organisms related and that share a common ancestor.
They both had a tail as an embryo.

What is the role of photosynthesis in the flow on energy throughout an ecosystem?
Hello!! I'm always here to help!!
_________________________
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.
