Use the graph and the information provided to answer the questions.
Stickleback fish protect themselves from predators with a thick covering of brownish plates. They feed on
small aquatic organisms and are preyed upon by bigger fish like trout. In a certain lake, the number of
stickleback fish was documented over a period of 30 years. During this time, the clarity of the lake water
also changed.
1. How did the occurrences of the different traits change over the 30-year period? Use evidence from
the graph to support your answer. Using what you know about natural selection and adaptation, what
generalization can you make based on these changes?
Explanation:
scam fakeeee
just kidding the answer is
every time the differences will change because of the large fishes which kill the small ones and the fishes het big like in one big fish there will be 100 of small fishes like the megladon
during this blood also leaks and the colour of the lake changes
Answer:
In each instance, the variations in fish populations are subject to change due to the predation of larger fish on smaller ones. As a result, the surviving fish grow larger, akin to the manner in which the Megalodon can have hundreds of smaller fish within its body. This process can also result in the release of blood, which has the potential to alter the color of the surrounding water body.

Answer:
Enzymes are important because they make the chemical reactions in cells happen quickly.
Enzymes, by speeding up biological reactions, ensure that all necessary activities in a cell can take place simultaneously and prevent one particular activity from overtaking the entire cell or organism. This is possible because enzymes allow chemicals to react more specifically with only certain substances rather than reacting indiscriminately with any number of different substances within cells.
The most famous example of this enzyme effect is when stomach acid reacts with pepsin that turns food into a liquid. The body then uses this liquid for absorption through the intestines where nutrients are then used throughout the body. It's important for people to have enough enzymes in order to digest their food fully however if

Answer: Biting into a piece of bread
Explanation:
Answer:
B Biting into a peace of bread
Explanation:
I took the test and as well. the first physical thing that changes whenever any type of food goes into your mouth is the way it breaks apart/turns into a smaller part of the food so that your esaphgous can swallow it. Hope this helped :)

Why are fossils important to developing a theory of evolution?
Answer:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms
Explanation:
Fossils are important evidence for evolution because they show that life on earth was once different from life found on earth today. ... Paleontologists can determine the age of fossils using methods like radiometric dating and categorize them to determine the evolutionary relationships between organisms
The preserved remnants or traces of extinct animals, plants, and other organisms are known as fossils. Because they demonstrate that earlier life on Earth was distinct from the life observed today, fossils are crucial pieces of evidence for evolution.
What is evolution?According to the idea of evolution, modern life forms have evolved from more ancient ones.
The original theory suggested that this occurred slowly and gradually, but fossil evidence suggests that the process occasionally went wrong and engaged in some very bizarre experiments.
Therefore, they demonstrate that earlier life on Earth was distinct from the life observed today, fossils are crucial pieces of evidence for evolution.

The genetic diversity of a rocky shore habitat declines precipitously as the climate warms, causing a decline in the number of species present. The decline of species along the rocky shore negatively affects the entire region, including bird populations and shallow offshore habitats. This scenario is best described as a change in the region's ______________________.
The scenario that is best described here is a change in the region's BIODIVERSITY. This measure (biodiversity) indicates the genetic/phenotypic variability found in a region.
Biodiversity refers to the genetic and phenotypic variability of the organisms found in a particular geographic region or the variety of life on the Earth's planet.
Biodiversity can be used to indicate the amount of variation at different levels (i.e., genetic, species, and ecosystem levels).
The different types of animals, plants and microorganisms that live in a forest represent an example of biodiversity.

The process in which impurities are removed from a mineral
Answer:
The removal of impurities is usually done chemically. For example, in the manufacturing of iron, calcium carbonate is added to the blast furnace to remove silicon dioxide from the iron ore. Zone refining is an economically important method for the purification of semiconductors.

Write an equation for the line with slope -5 and y-intercept of 14? O A. y = -5x - 14 O B. y = -5x + 14 HE 0 C. y = -5x + 18 O D. y = -5x + 6 HUSS
Answer:
The equation of a line is written in the form y=mx+b. ”m” is the slope and “b” is the y-intercept. Plugging in the given values, the equation of the line is y=-5x + 14.

Differentiate How
does telophase II differ from
telophase I?
Answer: Telophase I is the ending phase of the first division of meiosis which would split the parent cell into two daughter cells while telophase II is the ending phase of the second division of meiosis which would split the two daughter cell into four daughter cells and resulting in the end of the process.

Maxine miles runs a marathon in 2 hours and 40 minutes. most of the atp for this activity is supplied by:
Maxine miles runs a marathon in 2 hours and 40 minutes. Most of the ATP for this activity is supplied by AEROBIC glucose breakdown. ATP is the energy coin of the cell.
Cellular respiration refers to the metabolic processes by which aerobic cells produce ATP by using the energy stored in the chemical bonds of foods (e.g., glucose) and oxygen.
Muscle cells can produce ATP by both cellular respiration (aerobic conditions) and acid lactic fermentation (anaerobic conditions).
Acid lactic fermentation is a less efficient pathway than cellular respiration, but cellular respiration is slower than fermentation, thereby muscle cells use this pathway (acid lactic fermentation) when there is not enough oxygen in the body.
