Answer:
Glaciers are melting ice in the Arctic Ocean around the North Pole is melting faster with warmer temperatures. Permafrost is melting, releasing methane, a powerful greenhouse gas, into the atmosphere. Sea levels are rising, threatening coastal communities and estuarine ecosystems.
Explain how the boiling of water and the cooling of water vapor is a reversible reaction.
(think about hydrogen bonds between water molecules)
Answer: This is a reversible reaction because you can boil the water to make water vapor and when the water vapor is cooled down, it ill turn back into its original liquid, water. This occurs because of hydrogen bonding between water molecules.

Observe: An enzyme is a protein that facilitates certain cell processes. Click Release enzyme to release DNA helicase. What does this enzyme do to the DNA molecule?
Answer: It makes the DNA molecules split up into two separate strands of DNA.
An enzyme is a protein that facilitates certain cell processes makes the DNA molecule split up into two strands.
What does this enzyme (helicase) do to the DNA molecule?
DNA moves the nitrogenous bases, helping them to attach to the proper molecule. Complete the 2 molecules of DNA by dragging nucleotides to their corresponding locations.
The DNA enzyme helicase unzips the DNA strand in order that one side is often used as a template to form a replacement strand. DNA polymerase is another enzyme that takes nucleotides from the solution and bonds them to other nucleotides.
DNA helicase unwinds the double helix at the replication fork.
Therefore, the DNA molecule split up into two strands.

Summarize the importance of cells within the levels of organization in biological systems. Examine
the relationships between cells and other levels of organization in biological systems and to the
whole biological system.
Answer:
In biological system, cell is known as the basic unit of all organisms. Unicellular organism consist of one cell only but that single cell helps them to perform all the functional activity.
Levels of organization in biological systems is defined as the hierarchy of several components from smallest to complex in biological system.
Cell is one of the important part of Levels of organization in biological systems, as in multicellular organisms group of cells form tissue that create an organ and many organs together form organ system within an organism. The cell is basic unit in all organisms and without a cell, an organism can not develop.
The group of these organism formed from a small cell then form complex component of Levels of organization such as population, community, ecosystem and Biosphere (in sequential order).

Impressions of tropical swamp plants were observed on rocks in polar regions. The impressions were dark black imprints, which means the fossils are examples of . The fossils tell us that polar regions .
Answer:
the fossils are examples of... mineralization
The fossils tell us that polar regions... formed a supercontinent that divided and slowly drifted to polar regions
Explanation:
Mineralization is a type of fossilization where rich-mineralized water fills the pores of the dead tissues for a long time. Subsequently, when this water is evaporated, the excess of minerals is deposited on the tissues, thereby mineralizing organic tissues.
Fossils enable us to understand more accurately past climatic conditions from regions where these fossils were found. For example, the discovery of plant fossils closely related to tropical species in polar regions suggests that these regions were once a part of a super landmass known as Pangea that divided and drifted a long time ago (millions of years ago).

Based on radiometric dating, the oldest rocks scientists have found on Earth are 4.6 billion years old, but not ALL rocks are that old. Why might some rocks be 4.6 billion years old, and other rocks are only 2 billion years old, while yet others are only a few thousand years old? (Think about the rock cycle & use names of the different types of rocks in your answer!)
Answer: Meteorites spring from a variety of sources. ... More than 70 meteorites that have fallen to Earth have had their ages calculated by radiometric dating. The oldest of these are between 4.4 billion and 4.5 billion years old. Fifty thousand years ago, a rock hurled down from space to form Meteor Crater in Arizona
Explanation:
That is all I can think of
The rock cycle is a process in which the three types of rocks—igneous, sedimentary, and metamorphic—are continuously changed.
What is a rock cycle?The rock cycle explains how different types of rocks, such as sedimentary, igneous, and metamorphic rocks, change through time. These rocks are present in the lithosphere, which makes up the crust of the earth, but they are not evenly dispersed or spaced.
The soils are created from the weathered and eroded rocks. The rock cycle demonstrates how various types of rocks that enter and exit this cycle change and adapt.
Therefore, some rocks are 4.6 billion years old and other rocks are only 2 billion years old, while yet others are only a few thousand years old based on radiometric dating.

Which have more energy: 10 starch or 10 glucose molecules. Explain
Answer:
10 starch
Explanation:
Starch is a polycharraide and is made up of glucose. Glucose is a monocharraide and is the simplest sugar. So if we take 10 glucose molecules and 10 starch molecules the starch has more energy since it's more complex than glucose.

Answer:
Substrate inhibitor, activator or a neurotransmitter.
Explanation:
The original ligand was most likely a substrate inhibitor, activator or a neurotransmitter. A ligand is a small molecule that is able to bind to proteins by weak attractive forces such as ionic bond and hydrogen bonds etc. It also transmit signals in the process from one part to another part. It also act as inhibitor and activator of reactions in the process.

The concept of a transgene has been broadly understood for more than 100 years, as the advent of genetic research made its way into the 20th century. As time went by, technologies evolved, and transgenes became widely used during the late 1970s and early '80s. Which is one reason scientists produce transgenic organisms?
A) to create new species of organisms
B) to control microorganisms in the soil
C) to treat certain types of diseases
D) to prevent habitats from being destroyed
Answer:
C) To treat certain types of diseases
Explanation:
Scientists produce transgenic organisms to treat certain types of diseases. Hence, option C is correct.
What are transgenic organisms?An organism or cell is referred to as transgenic if its genome has been transformed by the intentional introduction of one or more foreign DNA sequences from another species. In the lab, transgenic organisms are created for scientific investigation. GMOs, or genetically modified organisms, are another name for transgenic organisms (GMOs).
Transgenesis enables the enhancement of the amount, overall quality, and particular nutritional composition of nutrients in animal products. Transgenic technologies might make it possible to increase or transmit features that are good for nutrition.
