Roller coasters, with their twists, turns, and loops, seem to defy everything we know about how objects move. Roller coaster designers use Newton's laws to
push people past their usual limits. Which statement identifies Newton's Law of Motion with the correct justification of that law? (DOK 2, AKS 8b)
OA Newton's first law is the law of inertia. Since an object at rest stays at rest, all roller coasters have to be pushed or pulled to get started.
OB. Newton's first law is the law of force and acceleration. Since the rollercoaster is so massive, it will require more force to accelerate
OC. Newton's third law of action-reaction states that for every action, there is an equal and opposite reaction. This means that as you push down on the
seat, the seat does not push back on you with an equal force.
OD. Newton's second law is the law of force and acceleration. Since the rollercoaster is so massive, it will require less force to accelerate.

A graph of KE vs the mass of an object is ___
Answer:
A non linear relationship
Explanation:
hope this helps.
A graph of KE vs the mass of an object is a non-linear relationship.
What are graphs?Graphs are the mathematical representations of numbers and data on graph paper. They are an easy way to see the changes in the data over time.
In nonlinear relationships, changes in any of the inputs are not proportionate to changes in the output. A nonlinear relationship produces a curve when it is plotted on a graph, whereas a linear relationship results in a straight line.
On a graph, kinetic energy has a linear relationship with respect to the mass of the moving object and a non-linear relationship with respect to how fast the object is moving.
Thus, the graph of KE will be a non-linear relationship.

Explanation:
2. Polar molecules and ions need a transport protein to
diffuse across the cell membrane.
TRUE
FALSE
Answer:
True
Explanation:
Only small hydrophobic nonplar molecules can go through the hydrophobic interior of the phospholipid bilayer. Therefore, polar molecules and ions need transport proteins to diffuse across the cell membrane, also called facilitated diffusion. An example is water, which is polar, and through osmosis diffuses through transport proteins called aquaporins.

28. Which statement best explains why cellular respiration in plants and
other organisms is dependent on photosynthesis?
Photosynthesis is one of the final steps in cellular respiration,
Photosynthesis absorbs materials that are catalyzed during cellular respiration.
Photosynthesis absorbs excess energy produced by cellular respiration.
Photosynthesis provides the materials that fuel cellular respiration.
Answer: Photosynthesis provides the materials that fuel cellular respiration.
Explanation:
Photosynthesis, the process through which green plants convert light to chemical energy. The energy that is gotten from sunlight by green plants, some protistans, and bacteria is used to produce sugar which is then converted to ATP by cellular respiration which is regarded to as the fuel that living things use.
Therefore, the statement that best explains why cellular respiration in plants and other organisms is dependent on photosynthesis is that photosynthesis provides the materials that fuel cellular respiration.
Answer:
Photosynthesis provides the materials that fuel cellular respiration.
Explanation:
A population of the Galapagos finch Geospiza fortis undergoes directional selection for larger bill size after Geospiza fuliginosa colonizes the same island. This is an example of:
Answer: character displacement
Explanation:
Character displacement is an evolutionary change which happens in a scenario whereby two identical species live in same environment. When this occurs, natural selection takes place which then favors a divergence based on the characters that the organisms possess.
Therefore, when a population of the Galapagos finch Geospiza fortis undergoes directional selection for larger bill size after Geospiza fuliginosa colonizes the same island is an example of character displacement.
What likely occurred in the nebula as a result of these changes?
Answer:
In the solar nebula, this likely grew out of inhomogeneties in the initial contraction. ... After this, the nebula became more transparent to solar radiation, and the nebula would have begun to cool. This would have allowed new compounds to form, growing as dust grains by condensation. Explanation:

In what way do two alleles for the some trait differ?
A. The are found on different chromosomes.
B. They consist of different sequences of DNA
C. They are produced by two different people.
D. They are complementary.
Answer:
B. They consist of different sequences of DNA
Explanation:
Alleles are contrasting or alternative forms of a gene. A diploid organism i.e an organism with two sets of homologous chromosome, contains two alleles for each gene that encodes a trait. Although the two alleles of that particular gene encodes the same trait, they can encode different phenotypes i.e way it is expressed because they contain different sequences of DNA.
For example, in a gene coding for height in pea plants, two alleles, T and t are responsible. Allele T codes for tall height (phenotype) while allele t codes for short height (phenotype). Although the two alleles are for the same trait, they differ in the content of their DNA sequence, hence, are expressed differently or variably.
Is hemoglobin a hormone?
Answer:
I'm really sorry it is not.
A new hormone called erythroferrone, which regulates the iron supply needed for red blood-cell production, has been discovered by researchers. Iron is an essential functional component of hemoglobin.
Hemoglobin is the iron-containing protein compound within red blood cells that carries oxygen throughout the body. It is made up of heme, which is the iron-containing portion, and globin chains, which are proteins. The globin protein consists of chains of amino acids, the "building blocks" of proteins.

Explanation:
Use your completed Fossil Primate Chart (on pp. 393–394) to answer the following questions. What geographic region(s) have numerous fossil primate discoveries? Why might fossil primates be common in these places? Identify one geographic region that has few or no fossil primates. Why might fossil primates be rare here? Choose one strepsirhine-like fossil primate and one haplorhine-like fossil primate, and list at least two traits that distinguish them. What do these traits suggest about their classification and relationship to living primates? Choose any two haplorhine-like fossil primates and list at least two traits that distinguish them. What do these traits suggest about their classification and relationship to living primates?
Answer:
Africa, Madagascar, Asia, and the New World.
Explanation:
Africa, Madagascar, Asia, and the New World are the geographic regions have numerous fossil primate discoveries. Fossil primates to be rare in the temperate regions because only a small fraction of the primates that have ever lived has been preserved as fossils due to of climatic and geological conditions of the region. The strepsirhines like fossil primate containing wet-nosed primates, whereas haplorhines like fossil primate containing dry-nosed primates. These traits suggest that the living primates are evolved from these extent primates so that's why they are classified in the same phylum.
