Answer:
If your just looking for the "why" then this is what i do know about it.
Explanation:
Changes in pH cause amino acids' component atoms and molecules to ionize. This can make an enzyme change shape. These shapes determine function, so changing the shape can impair the enzyme's function, preventing it from speeding up chemical reactions.
Higher temperatures disrupt the shape of the active site, which will reduce its activity, or prevent it from working. The enzyme will have been denatured . Enzymes therefore work best at a particular temperature.

Signal transduction pathways lead to a cellular response. Which of the potential cellular responses is most likely to occur in response to cortisol?
Familial Down syndrome is similar to primary Down syndrome in that it is caused by trisomy 21. However, in familial Down syndrome, all or part of the third copy of chromosome 21 has translocated onto another autosome, typically chromosome 14. In cases of familial Down syndrome, one of the parents of the affected child is often a carrier of a translocated chromosome. The translocation carrier parent does not have Down syndrome because he or she has a total of two copies of chromosome 21.Suppose that a woman is a translocation carrier of chromosome 21 on chromosome 14. She conceives six zygotes with a normal man who carries no aneuploidies. Match the description of the chromosomes inherited by each zygote with the viability of the zygote.
Viable Normal or Translocation carrier,there are;
- Two normal copies of 14 and two normal copies of 21.
- One normal copy of 14 and one normal copy of 21, then one 14 to 21 translocation.
Then viable with down syndrome will include:
- One 21 to 14 Translocation, two normal copies of 21 and one normal copy of 14.
Then the VIABLE with down syndrome will be:
- One normal copy of 14 with two normal copies of 21
- Two normal copies of 14 with one normal copy of 21
- One 21 to 14 Translocation,a normal copy of 21,then two normal copies of 14.
100 POINTS!!! ANSWER ASAP!! Research a scientific belief that was accepted centuries ago, but has since been
disproved. How does it support the use of the term "scientific theory" instead of
"scientific fact?"
Answer:
A scientific theory is an explanation of an aspect of the natural world that can be repeatedly tested and verified in accordance with the scientific method, using accepted protocols of observation, measurement, and evaluation of results. Where possible, theories are tested under controlled conditions in an experiment.[1][2] In circumstances not amenable to experimental testing, theories are evaluated through principles of abductive reasoning. Established scientific theories have withstood rigorous scrutiny and embody scientific knowledge.[3]
The meaning of the term scientific theory (often contracted to theory for brevity) as used in the disciplines of science is significantly different from the common vernacular usage of theory.[4][note 1] In everyday speech, theory can imply an explanation that represents an unsubstantiated and speculative guess,[4] whereas in science it describes an explanation that has been tested and widely accepted as valid. These different usages are comparable to the opposing usages of prediction in science versus common speech, where it denotes a mere hope.
The strength of a scientific theory is related to the diversity of phenomena it can explain and its simplicity. As additional scientific evidence is gathered, a scientific theory may be modified and ultimately rejected if it cannot be made to fit the new findings; in such circumstances, a more accurate theory is then required. That does not mean that all theories can be fundamentally changed (for example, well established foundational scientific theories such as evolution, heliocentric theory, cell theory, theory of plate tectonics, germ theory of disease, etc.). In certain cases, the less-accurate unmodified scientific theory can still be treated as a theory if it is useful (due to its sheer simplicity) as an approximation under specific conditions. A case in point is Newton's laws of motion, which can serve as an approximation to special relativity at velocities that are small relative to the speed of light.
Scientific theories are testable and make falsifiable predictions.[5] They describe the causes of a particular natural phenomenon and are used to explain and predict aspects of the physical universe or specific areas of inquiry (for example, electricity, chemistry, and astronomy). Scientists use theories to further scientific knowledge, as well as to facilitate advances in technology or medicine.
As with other forms of scientific knowledge, scientific theories are both deductive and inductive,[6] aiming for predictive and explanatory power.
The paleontologist Stephen Jay Gould wrote that "...facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts."[7]

Inez has two beakers that contain ethanol. One beaker contains 150 mL of liquid. The other beaker contains 300 mL of liquid. What can Inez expect to observe when she compares the properties of the liquid in the beakers.
The correct answer is B. The melting point of the liquid in each beaker is the same.
Since both beakers contain ethanol, Inez can expect the liquids in the beakers to have the same chemical properties, such as the molecular structure, boiling point, and density that are present in option A.
What is ethanol?If Inez adds a small object (like a grape or a paper clip) to each beaker, she may observe that the object sinks faster in the beaker with the smaller volume of liquid as there is less liquid to displace, and many factors like density and surface area play an important role in this, as the liquid in the larger beaker will be more massive and may feel heavier than the liquid in the smaller beaker, and if Inez were to leave both beakers out in the open air, the ethanol in both beakers would eventually evaporate, but at different rates.
Hence, Inez can expect the liquids in the beakers to have the same chemical properties, such as the molecular structure, boiling point, and density, that are present in option A.

Ions are
Atoms with more neutrons than protons
Atoms with a positive or negative charge
Atoms with no charge
Atoms with more protons than neutrons
Atoms that are joined together in fixed proportions
Answer:
Ions are atoms with a positive or negative charge.
Explanation:
Ions are atoms or molecules that, when subjected to the phenomenon of ionization, gain or lose electrons, ceasing to be neutral and acquiring an electric charge.
The charge that atoms or molecules possess can be positive —if it has lost electrons— or negative when it acquires electrons. The negatively charged particle is called anion, and when it is positively charged cation.
The other options are not correct because of:
There are usually as many or more neutrons than protons. Uncharged atoms are neutral. The number of protons or neutrons does not affect the electric charge of the atom.Atoms that joined in fixed proportions can form molecules.THIS ORGANELLE IS A VERY IMPORTANT FACTOR FOR MITOSIS AND MEIOSIS
Answer:
One of the characteristics of living things is the ability to replicate and pass on genetic information to the next generation. Cell division in individual bacteria and archaea
usually occurs by binary fission. Mitochondria and chloroplasts also replicate by binary fission, which is evidence of the evolutionary relationship between these organelles and prokaryotes.
Cell division in eukaryotes is more complex. It requires the cell to manage a complicated process of duplicating the nucleus, other organelles, and multiple
chromosomes. This process, called the cell cycle, is divided into three parts: interphase, mitosis, and cytokinesis. Interphase is separated into three functionally
distinct stages. In the first growth phase, the cells grows and prepares to duplicate its DNA. In synthesis, the chromosomes are replicated. The cell prepares to divide. In mitosis, the duplicated chromosomes are separated into two nuclei. In most cases, mitosis is followed by cytokinesis, when the cytoplasm divides and organelles separate into daughter cells. This type of cell division is asexual and important for growth, renewal, and repair of
multicellular organisms.
Cell division is tightly controlled by complexes made of several specific proteins. These complexes contain enzymes called cyclin-dependent kinases (CDKs), which turn on
or off the various processes that take place in cell division. CDK partners with a family of proteins called cyclins. One such complex is mitosis-promoting factor (MPF),
sometimes called maturation-promoting factor, which contains cyclin A or B and cyclin-dependent kinase (CDK). CDK is activated when it is bound to
cyclin, interacting with various other proteins that, in this case, allow the cell to proceed from G2 into mitosis. The levels of cyclin change during the cell cycle. In
most cases, cytokinesis follows mitosis.

Juan and his science class are constructing models of sugar crystals. He wants his model to show how the sugar molecules move in the crystal. He is using plastic foam balls to represent the sugar molecules. How should he put the plastic foam balls together to make his model? O A. Connect them with stiff springs B. Fill a clear cube with them O C. Glue them together D. Place a few of them in a plastic bag
Answer:
The correct answer is option B. "Fill a clear cube with them".
Explanation:
Sugar crystals, colloquially known as "rock candy", are conglomerates of sugar molecules that are formed when sugar-saturated water are cooled. Sugar crystals are arranged in a three dimensional repeating pattern, forming a cube like structure. Therefore, Juan could fill a clear cube with its plastic foam balls to represent sugar crystals. I attached an image of sugar crystals dissolving in water as reference.

that is true.!
the earth is a closed system
Earth is a closed system, therefore, it's true.
A closed system simply means a system where only energy is transferred in the surroundings. On the other hand, an open system is one where matter and energy can be transferred.
It should be noted that Earth is a closed system due to the fact that only energy can be naturally transfered in the atmosphere. In this case, it's neither gaining matter nor losing it.
Therefore, the statement is true.
