Answer:
As DNA replication continues and the replication bubble expands, the parental double helix is unwound and separated into its two component strands. This unwinding and separating of the DNA require three different types of proteins: helicase, topoisomerase, and single-strand binding proteins.

recently, state forests and parks like yellowstone national park which contain varieties of flowering trees and shrubs, have started to erect signs that state, take nothing but pictures, leave nothing but footprints. which argument best supports why these signs are being placed in state forests and parks?
The argument that best supports why the signs are placed in the parks is that humans have the capacity to cause damages to the stability of ecosystems through their actions.
By removing tissues of plants or even entire plants, the stability of the entire park can be disrupted depending on the role such a plant plays in the ecosystem. Some species of organisms in the ecosystem play key roles and their removal or damages may cause significant disruption to the entire ecosystem.
Also, by leaving things that can be harmful to the plant species in parks, immeasurable damages can be done to the entire ecosystem.

The best argument that supports the signs being placed in state forests and parks is: humans are capable of damaging the stability of the ecosystems by removing trees and shrubs.
Different components in an ecosystem interact with each other to ensure biodiversity is sustained. Some species of an ecosystem play important roles and a disruption or removal of such key species would cause disruption in the ecosystem.
Trees and flowers in this said park play important roles in the ecosystem of the park. If they are damaged or removed from the ecosystem, the biodiversity of the ecosystem will be impacted which will cause instability of the ecosystem.
Therefore, the best argument that supports the signs being placed in state forests and parks is: humans are capable of damaging the stability of the ecosystems by removing trees and shrubs.Learn more about ecosystem stability on:

what is the difference in solubility of triglyceride and the products of their hydrolysis
Answer: Triacylglycerols are the major constituents of oils and fats of both plant and animal origin.
Explanation:
Hope this helps.
The products of hydrolysis of triglycerides are fatty acids and glycerol. While fatty acids, like triglycerides, are insoluble in water, glycerol is soluble in water.
Why are triglycerides insoluble?Triglycerides are esters of fatty acids and alcohol, mostly glycerol. The fatty acid chains are inked to the glycerol molecules with the help of covalent bonds.
This means that the triglyceride molecule is uncharged and will therefore remain insoluble in water but soluble in organic solvents.
Also, products of hydrolysis of triglycerides are fatter acids and glycerol. While fatty acids will remain insoluble in water, glycerol is soluble in water.
Glycerol is alcohol with 3 hydroxyl groups, this is why it is also called a polyol. They are able to hydrogen bonds with the nearby water molecules.
Therefore, triglycerides and fatty acids are insoluble and glycerol is soluble in water.

Which job description refers to the work of the mitochondrion?
Mitochondria is called as the “powerhouses of the cell,” which produce the energy necessary for the cell's survival and functioning.
What is Mitochondria?A mitochondrion is defined as an organelle found in the cells of most eukaryotes such as animals, plants and fungi which has a double membrane structure and uses aerobic respiration to generate adenosine triphosphate, which is used throughout used as a source of chemical energy in the cell.
It is known as the "powerhouse of the cell", generating the energy needed for the survival and functioning of the cell.
Through a series of chemical reactions break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.
Thus, mitochondria is called as the “powerhouses of the cell,” which produce the energy necessary for the cell's survival and functioning.

A population of rhinos in Africa is 112. this year there were 17 births and eight deaths in the population. What is the change in population? Do we have a positive, negative, or zero change in population? How many members are in the new population?
Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. work for calculating the new population
Explanation:
Why anti-poaching?Rhinos have inhabited the African continent for over a million years and they play a huge role in their ecosystems. The illegal trade in powders made from their horns, which in some countries in Asia is still considered a medicine or simply a symbol of wealth, nearly led to the extinction of the African rhino.
In 1875, there were still more than 1,000,000 rhinos living in the vast grasslands of Africa. Today the populations of the two species of black rhino and white rhino are estimated to contain about 5,000 and 20,000 animals respectively. The senseless killings continue. Since 2007, the number of rhinos hunted in Africa has increased by almost 9,000%.
It is therefore our call to stop the slaughter of rhinos with all our might.

Which of the following adaptations helps alpine animals survive the cold winter? a. Reduced lung size b. Low levels of hemoglobin c. Hibernation d. Large legs, ears, and tails.
Hibernation is an adaptation that helps alpine animals to survive the cold winter. Hibernation helps to store energy.
Hibernation is an adaptation that helps to store energy by decreasing the metabolic rate.
This adaptation (hibernation) is observed in animals living in extremely cold conditions (e.g., alpine animals).
The hibernation adaptative strategy is characterized by an excessively low temperature in the body, slow breath rate, slow beats (heart rate), and low metabolic rate.
