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 ______________________.

Answers

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.

Why are fossils important to developing a theory of evolution?

Answers

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.

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.

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.

Answers

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.

Describe why enzymes are important in all living organisms?

Answers

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
