9. A protein molecule which is denatured, has
a. split into smaller molecules
c. Changed its shape
b. combined with another molecule d. been diluted
Answer: B. combined with another molecule
Explanation:
i just took the test
Proteins are macromolecules composed of amino acid chains joined through peptide bonds. A denatured protein molecule has changed its shape. Thus, option c is correct.
What is protein denaturation?Protein denaturation is a process where the proteins under unfavorable conditions like temperature, chemicals, and pressure result in an alteration in their functions.
The basic structural organization of the proteins contains primary, secondary, and tertiary formation that gets altered at high temperatures resulting in the breaking of the covalent bonds and disruption of the amino acid chain.
This results in the protein breaking and forming the primary structure that leads to alteration of the shape and conformation. This change results in loss of the function and activity of the protein.
Therefore, option c. the denatured proteins result in alteration in shape.

Explain three cause and effect relationships between the human activities and the measurable changes in the Earth system represented in the Understanding Global Change model
Answer:
Humans are gradually altering the climate and the earth's temperature through burning fossil fuels, destroying forests, and rearing animals.
Explanation:
This significantly increases the amount of greenhouse gases already present in the atmosphere, increasing the greenhouse effect and contributing to global warming.
Climate change is mostly caused by the greenhouse effect. Some gases in the Earth's atmosphere act as greenhouse glass, trapping heat from the sun and preventing it from escaping into space, causing global warming.

How are water molecules able to bond to each other?
Water has a remarkable ability to cling to itself and other substances. The propensity of water molecules to be attracted to other water molecules, allowing water to be a "sticky" liquid, is described by the property of cohesion.
Which bond is present between water?The difference in charge between slightly positive hydrogen ions and other, slightly negative ions causes hydrogen bonds, which are electrostatic forces.
Hydrogen bonds form between adjoining hydrogen and oxygen atoms of adjacent water molecules in the case of water. A hydrogen bond is formed when individual water molecules attract each other.

Answer:
Radiocarbon dating
Explanation:
Radiocarbon dating is a technique for determining the age of carbon-based materials derived from live beings. By measuring the quantity of carbon-14 in a sample and comparing it to an internationally accepted reference standard, an age may be determined. Radiocarbon dating is based on the basic principle that all living organisms absorb carbon from the atmosphere and food sources around them, including a small quantity of naturally radioactive carbon-14. When a plant or animal dies, it stops absorbing carbon, but the radioactive carbon it has stored decays.
This technique allowed multiple peoples DNA to be compared to look for similarities and differences in order to solve crime

Changes in environmental conditions always result in new ecosystems and loss of biodiversity characterized by an increase in the number of some species, the evolution of new species, and the extinction of some species.
Changes to the environmental conditions can indeed result in new ecosystems and a change in the species equilibrium.
Ecosystem disruptionThe abiotic conditions of an ecosystem determine the kind of species that will inhabit the ecosystem
A change to the abiotic or environmental conditions will likely result in a new ecosystem entirely. Organisms that are able to adapt to the changes will gradually fade off the ecosystem while those that are able to withstand the changes will proliferate and dominate the populations of organisms in the ecosystem.
