In one or two sentences, explain what the main impact tsunamis cause on humans .why is it difficult to avoid a tsunamis
Answer:
Many people die from tsunamis because of drowning, and injuries such as broken limbs and head injuries can be caused. It's difficult to avoid tsunamis because they're hard to predict.
1 impact of tsunamis
A major impact of tsunamies on Humans is the damage that they do to everything. They don't just do damage to Property and Structures, they do damage to people's lives, and ecosystems in the water and also ecosystems near the water. The water has such a high speed and force that it can tear down buildings as you must have seen in movies. That is for obvious! But how do they effect ecosystems? They do that because when they are coming towards land, then they're carrying lots of ecosystems inside the waves, then, the animals in that go with the wave on the land, and then stay on the land while the water goes back to the ocean. So the thing is that the water needing animals will die in this situation. So they're damaging the ecosystems also.
Why is it difficult to avoid a tsunami?
The main thing is that natural disasters can't be avoided by humans in anyway. Humans don't have the capabilities to stop these things because these are the miseries of the world which we can't avoid. The reason why these happen is because of earthquakes underwater or also meteors falling on water. So that's why, these are unavoidable since we can't stop earthquakes and meteors. But we can put some effort into making the damage less by making giant walls and protection things. There are many technologies that can do this, but still, it will be hard since the water is liquid form, and it will take the form of it's container, meaning it will flow wherever it can. That's why it's HARD to avoid them.
Thanks!

1.) Compared to wave A, wave B has a _____.
A.) longer wavelength and lower frequency
B.) shorter wavelength and lower frequency
C.) shorter wavelength and greater frequency
D.) longer wavelength and greater frequency
2.) When drawn on a coordinate plane with the x-axis as the baseline, a wave with a crest that is closer to the baseline has a smaller _____.
A.) amplitude
B.) wavelength
C.) equilibrium
D.) frequency
3.) A student moves the end of a compressed coiled spring up and down to demonstrate wave motion. She then moves the compressed coiled spring faster but keeps everything else the same. Which characteristic will increase?
A.) wavelength
B.) frequency
C.) amplitude
D.) crest
Answer:
first answer is B second answer is a and third answer is d
Compared to wave A, wave B has a shorter wavelength and lower frequency. So, the correct options of 1, 2 and 3 are B, A and D.
What is Wave?A wave is defined as a propagating dynamic disturbance of one or more quantities that may be periodic, in which case those quantities oscillate repeatedly about an equilibrium value at some frequency.
Frequency and wavelength can be calculated by this formula,
[tex]v=\lambda f\\v = velocity\\\lambda = wavelength\\f = frequency[/tex]
A wave with a crest that is closer to the baseline has a smaller amplitude. When compressed coiled spring faster but keeps everything else the same, the crest will increase.
Thus, the correct options of 1, 2 and 3 are B, A and D.

A bat wing is more similar in anatomical structure to a cat forelimb than to a bird wing. Answer the following questions about these structures.
Which pairs are homologous structures?
Which pairs are analogous structures?
Based on this, do you think a bat is more closely related to a cat or a bird? Explain your answer.
Answer: Which pairs are homologous - structures? The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale, In short term it is having the same relative position, value, or structure
Which pairs are analogous structures? - Examples of analogous structures range from wings in flying animals like bats, birds, and insects, to fins in animals like penguins and fish. Also in short term it means comparable in certain respects, typically in a way which makes clearer the nature of the things compared.
Explanation: I do believe cats since bats actually belong to the super-order Pegasoferae, which contains horses, cats and dogs, cows, whales and hedgehogs.

In a group of dogs, some individuals have short fur and others have long fur. In this gropp,
the gene for the fur length trait has two alleles. The allele F is for short fur, and the allele fis
for long fur.
Marley, a dog from this group, has long fur. Marley has two alleles for long fur.
Based on this information, what is Marley's phenotype for the fur length trait?
FF
FI
short fur
long fur
Answer:
long fur
Explanation:
Phenotype refers to an individual's observable traits, such as height, eye color, and blood type ( the outside apperance ) so what is the dog's fur can be discribed as ? the answer is long fur
