Guppies are small fish that live in South American rivers. They can have different-sized spots on their bodies. The river bottoms are covered in rocks. Guppies with spots that are the same size as the rocks on the bottom are harder for bigger fish to see and catch. The diagram above shows a population of guppies that lived in a river. Scientists had previously only seen guppies with medium or large spots in this river; they had never seen any guppies with any other spot sizes. The diagram below shows how the population changed after many generations.
• Karina says the change in the guppy population was caused by a mutation.
• Miles says the change was caused by a change in the environment.
• Zora thinks both Karina and Miles are correct.
Who do you think is right? Explain what happened to the guppies over many generations
The statement 'Karina says the change in the guppy population was caused by a mutation' is correct. Mutations change the frequency of phenotypic traits in a population across generations.
What is evolution?The word 'evolution' refers to descendence with modification which especially happens due to the process of natural selection.
The mutations in the genetic material serve as raw material for natural selection and consequently for evolution.
In this case, Karina must be right because the change in the frequency of the phenotype can be caused by the emergence of beneficial mutations in individuals that live in a given environment.
These types of mutations (beneficial mutations) can fix and increase their frequency across generations.

Photosynthesis is vital for maintaining levels of atmospheric oxygen. please select the best answer from the choices provided t f
Photosynthesis is a key determining process to regulate the level of atmospheric oxygen. This statement is true.
What do you mean by Photosynthesis?Photosynthesis may be defined as a process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Without the process of photosynthesis, the evolution of oxygen can not be imagined. Photosynthesis takes carbon dioxide from the atmosphere, and in respect of this oxygen is liberated in our surroundings.
Therefore, Photosynthesis is a key determining process to regulate the level of atmospheric oxygen.

Mr. D asked four students to identify characteristics of organisms in the kingdom Eubacteria. Which student
correctly identified two characteristics of Eubacteria?
Student Cell Organization Nucleus Present
Glenda single-celled
Sam single-celled
yes
Tremica multicellular
no
Thurman multicellular
yes
no
Answer:
The student who correctly identified the two characteristics of Eubacteria was Glenda (option A).
Explanation:
Eubacteria are unicellular prokaryotic microorganisms, provided with membrane and cell wall.
One of the distinctive characteristics of Eubacteria is their inability to associate and form tissues, as eukaryotic bacteria do, so they are unicellular organisms. In addition, they lack a nucleus, their genetic information is dispersed in the cytosol and they do not possess most of the organelles.
Eubacteria can be found on any surface and some of them can be considered harmful to living beings.
Other options:
None of the other students were able to identify these two characteristics of the Eubacteria.

Which of the following describe a way climate change makes droughts more
extreme?
Choose the three correct answers. (1 point)
-rain instead of snowfall
-storms increase in energy
-increased evaporation
-increased snowmelt
Climate change has the tendency to make droughts more extreme by increasing the rate of evaporation from land surfaces.
What is climate change?Climate change refers to the unpredictability of climate away from what used to be considered normal.
Climate change is brought about by global warming, an increase in the annual global temperature of the globe.
Climate change has the tendency to make droughts more extreme in that increased temperature leads to an increase in the rate of evaporation from ground surfaces.
Droughts are caused by the absence of water, the drier a place is, the more the drought.

This layer exists in the Tropical Rain Forest but not the Temperate Deciduous Forest.
Answer:
The emergent layer is unique to tropical rainforests
Explanation:
Tropical rainforests are rainforests general found in areas around the world in which there is no dry season. Each month in these regions has an average precipitation of at least 60 mm.
Temperate Deciduous Forest exists in temperate regions.
The major difference between the tropical rain forest and the temperate deciduous forest is the presence of an emergent layer in the tropical rain forest.
The emergent layer of a tropical rain forest is characterized by a small number of very large trees. These trees mostly grow above the height of the general canopy layer.

A radio wave travels through space with a frequency of 2 x 104 Hz. If the speed of the radio wave is 3 x 108 m/s,
what is the wavelength of this wave?
O 6 x 10^12 m
O 1 x 10^4 m
O 6.7 x 10^-4 m
O 1.5 x 10^4 m
The wavelength of the radio wave is [tex]1.5 * 10^4[/tex] meters.
The wavelength of a wave is the distance between two adjacent points that are in phase, or in the same phase as their cycles on the wave. For example, the distance between two successive peaks or troughs of a sine wave is known as a wavelength.
A wave's speed, wavelength, and frequency can be calculated using the following formula:
Wavelength = speed / frequency
Substituting the given values:
Wavelength = [tex]3 * 10^8 m/s / 2 *10^4 Hz[/tex]
Wavelength = 15,000 meters or 1.5 x [tex]10^4[/tex]meters

Explanation:
Fernando is an engineer at an amusement park who is experimenting with changes to the setup for a magnetic roller coaster ride. In one ride, there are two identical roller coaster cars (red and yellow) that start on opposite sides of a large magnet located in the center of a station. He moves both cars, so each car ends up one space farther away from the large magnet.
How did the potential energy of the two cars change? Did the potential energy of one car change more than the other? Why do you think
I think that the potential energy of the cars will go down because the cars are moving farther away from the big magnet. Since the pols of the cars and big magnet are opposite and not the same they would want to attract if they got close to the big magnet, but since Fernando is pulling the carts away they loose that potential energy. I also think that the red cart changed more than the yellow cart because it is closer to the magnet which can have a lot of potential energy and he is now bringing the cart away from it. In conclusion, I think the red cart had a greater change in potential energy and the two cars changed in potential energy too.
