Answer:
Wave length x Wave frequency
Explanation:
The wave length is measured in meters X the wave frequency, measured in hertz (Hz)
Answer:
The speed of a wave is a property of the medium changing the speed actually requires a change in the medium itself. If the medium does not change as a wave travels, the wave speed is constant.
TO CALCULATE IT
Wave Speed Formula
Speed of the tsunami (meters/second) is equal to the square root of g (the acceleration due to gravity, which a constant 9.81 meters/second) times the water depth (d) at which the disturbance occurred (meters).

Why does blue light cause a negative photosynthesis rate? (If algae is grown under blue light, why is the rate of photosynthesis slower than other colors?)
Blue photons drive the photosynthetic reaction, although from an energy standpoint, one might consider them less efficient than green or red photons because their high energy isn't fully utilized; some of the energy is essentially lost compared to photosynthetic photons with a longer (less energetic) wavelength.

In your own words, explain why the landscape of Florida has not changed over time like that of Colorado.
Answer:
The landscape of Florida has not changed over time like that of colorado because the rock structures of colorado are much older than that of florida. Colorado also experiences a lot of tectonic plate movement. This led to the colorado river flowing through it and through weathering and erosion the landscape changed. Florida is not affected by the same things so the landscapes change in different pace
The landscape of Florida has not changed over time like that of Colorado because Colorado is a frigid mountainous area while Florida has a humid subtropical climate.
What do you mean by Landscape?The landscape of an area may be defined as the representation or visible region of a defined area that is set up by artificial boundaries.
The region of Colorado experiences the movement of tectonic plates that changes the area of river flowing which leads to the activities like weathering and erosions.
While Florida experiences a hot and humid climate with stable conditions. Hence, the change in landscape is not rapidly seen in Florida.
Therefore, it is well described above.

Inbreeding can cause physical defects because _____________ are passed on to the next generation.
a.
DDT
c.
PCBs
b.
estrogen
d.
deleterious recessive genes
Answer:
d. deleterious recessive genes
Explanation:
Inbreeding occurs when offsprings result from two individuals who have a similar genetic sequence because they are closely related. The offsprings borne are prone to be defective because of the similarity between their parents' genes. Inbreeding depression also occurs because the offsprings are not physically fit and can easily succumb to death.
The opposite of inbreeding is crossbreeding which prevents the negative traits that are associated with inbreeding.
WOULD THERE BE ANY BACTERIA

.............
...............
Do you think there would be
some bacteria in it? If so, in
which part of the aquarium
would they be occurring in
abundance and what for?
.................
Answer: yes, many different kinds
Explanation: bacteria are everywhere and so will be found in aquaria. Aquarium health is dependent on bacteria. Fish excrete ammonia which is toxic. Bacteria such as Nitrosomonas and Nitrococcus convert ammonia to nitrite, and Nitrobacter converts nitrite to nitrate which is relatively harmless. Bacteria such as Pseudomonas stutzeri and Bacillus subtilis remove nitrate and organic waste. There are also bacteria in fish intestines, and other bacteria that can cause fish diseases or create undesirable conditions such as Pseudomonas fluorescens, Vibrio, Flexibacter or Aeromonas and anaerobes that reduce sulphates to hydrogen sulphide.
