1b: Oceans are an important source of food. They host 80 percent of the planet's biodiversity, and are the largest ecosystem on Earth.
2: Carbon dioxide (CO2) emissions from burning fossil fuels are making the world's oceans more acidic. In the water, CO2 reacts to form carbonic acid, and over the years, the ocean's acidity has increased by 30 percent because so much of the excess man-made CO2 is being drawn into the water.
3: Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.

Which geologic feature forms when tectonic plates collide?
A
buttes
B
valleys
C
sinkholes
D
mountains
Answers
Answer:
D. Mountains
Explanation:
Sinkholes are caused by cave ins, valleys are in between mountains, and buttes are most likely caused by erosion after the sand and soil got blown away. Mountains are caused by two plates slamming into each other and going sky-wise.
The geological feature forms when tectonic plates collide mountain. The correct option is D.
What is mountain?A mountain is an elevated portion of the Earth's crust that typically has steep sides with exposed bedrock.
Although definitions differ, a mountain differs from a plateau in that it has a smaller summit area and is typically higher than a hill, rising at least 300 meters above the surrounding land.
The world's tallest mountain ranges form when plates of Earth's crust collide and buckle up like the hood of a car in a head-on collision, a process known as plate tectonics.
The mountain may take tens of millions of years to rise. The plates move slowly, but when they collide, they may not only contribute to the formation of a mountain, but also shake things up.
Thus, the correct option is D.

Describe the group of frogs in the image.
Answers
the frogs are all about the same size, varying in color and pattern.
The frogs are approximately the same size, but they exhibit a range of colors and patterns.
What is genetic variation?The size of the frogs being similar and varying in color and pattern may be due to genetic variation within the population. This means that the frogs have different genetic traits that determine their color and pattern, but they still share the same general body size due to the genetic makeup of the population.
It's also possible that environmental factors, such as diet or temperature, could play a role in color and pattern variation, but not necessarily in size variation. Additionally, if the frogs are from the same species, their overall body size would be expected to be relatively similar due to shared genetic traits that determine their basic body structure.

Answer:
1. Antonie van Leeuwenhoek made the first microscope and used it to look at bacteria and study bacteria, and Robert Hooke studied cells and saw cavities in the cells that looked like small boxes - he discovered plant cells! he recognized cells as the basic unit of life, a basis for Cell Theory.
2. cell theory is: every living organism is made of one or more cells, cells are the smallest units of life ( that have the properties of a living thing), All cells come from other cells - all living things come from other living things. This relates to every living thing because all living things come under cell theory - like all living things are made of cells
3. prokaryotes, like bacteria, doesn't have a nucleus covered in a membrane. a eukaryotic cell, like an animal cell, has a membrane covered nucleus. just like the nucleus, in eukaryotes the organelles are not membrane bound. in prokaryotes, the organelles are membrane bound. In prokaryotes the DNA form is circular, while the DNA form in eukaryotes is linear. there are more, but i couldn't list them.
4. Example for prokaryote: the famous (or infamous) E. Coli bacterium. example for eukaryote: Humans!
5. Single-celled organisms (unicellular organisms) have all the functions necessary for their survival in the single cell. Multicellular organisms (many celled organisms), however, need many cells to survive and carry out all the functions necessary for their survival and do the different tasks each cell is supposed to do.

Rainbow smelt and yellow perch attempt to occupy the same area. The more aggressive smelt survive; the perch do not.
Limiting factor-
Explain-
A severe flood brings a lot of sediment and silt into Lake Winnipeg. The turbidity of the lake increases greatly.
Limiting factor-
Explain-
A drought decreases the water level in Lake Winnipeg. The carrying capacity of the lake decreases.
Limiting factor-
Explain-
Due to the introduction of rainbow smelt, Lake Winnipeg becomes crowded and some fish species do not survive.
Limiting factor-
Explain-
Since northern pike prey on yellow perch, an increase in the perch population causes an increase in the pike population.
Limiting factor-
Explain-
Many fish die due to an increase in water temperature.

Rainbow smelt and yellow perch attempt to occupy the same area. The more aggressive smelt survives the perch does not, showing the density-dependent limiting factor and all other question is also a density-dependent limiting factor.
What is a density-dependent limiting factor?The density-dependent limiting factor is defined as the factor that affects the growth and size of the population that varies with the population density, disease predation, and competition are the density-dependent limiting factor.
While a density-independent limiting factor is considered as any force that change the size of the population but does not affect the density of the population.
In the given question Rainbow smelt and yellow perch attempt to occupy the same area. The more aggressive smelt survives the perch not is an example of density-dependent limiting factor.
Therefore, examples in the given question show density-dependent limiting factors.
