How dose the force of the car change as the mas of the car increases
Answer:
Increases.
Explanation:
According to Newton's Second Law of Motion:
F = ma
So, if we keep the acceleration constant:
F ∝ m
F is directly proportional to m, which means if we increase the mass, the force will also increase and vice versa.
Hence, If the mass of the car increases, Force acting on it also increases.

what is the historical evidence on file for fossils
Answer:
Fossils are crucial evidence for evolution because they demonstrate how life on Earth used to be different from how it is now. Paleontologists can use radiometric dating to estimate the age of fossils and categorize them to discover the evolutionary connections between creatures.
How does the friction affect the total time a pendulum is in motion? And what could cause this friction in the real world?
Answer:
Without friction, the equation of motion for a pendulum of length L is,
md2θdt2+mgsin(θ)L=0.
Or for small oscillations, (i.e., sin(θ)≈θ),
md2θdt2+mgθL=0.
Assuming an initial angle θ0 and a pendulum that starts at rest, the solution to this differential equation is,
θ(t)=θ0cos(gL−−√t).
Frictional force adds an additional damping term into the equation of motion,
md2θdt2+λdθdt+mgθL=0,
where λ is a coefficient of kinetic friction.
Assuming an initial angle θ0 and a pendulum that starts at rest, the solution to the damped differential equation is,
θ(t)=θ0e−12λmtcos((gL−λ24m2−−−−−−−−√)t).
(Note: If you would like to consider closed form solutions for large angles, I would recommend consulting the mathematics section. The solutions to that problem are called elliptic integrals of the first kind.)
Friction decreases the total time that a pendulum is in motion.
If we consider a pendulum in motion, in accordance with Newton's law, the pendulum will continue moving unless it is acted upon by an external force.
In the case of the pendulum, the external force that acts on it is the air resistance or friction. As a result of this friction, the pendulum will eventually come to a stop.
In the real world, the surface of objects cause friction which causes moving objects to stop.

2. Explain why glucose continues to enter a cell, even when the concentration inside the cell might be higher than outside.
Answer:
Both diffusion and facilitated diffusion are driven by the potential energy differences of a concentration gradient. Glucose enters most cells by facilitated diffusion. ... Na+ is maintained at low concentrations inside the cell and K+ is at higher concentrations. The reverse is the case on the outside of the cell
Glucose continues to enter a cell, even when the concentration inside the
cell might be higher than outside as a result of the process known as active
transport.
Active transport involves the movement of molecules through a
cell membrane against the concentration gradient. Examples include:
Antiport Pumps.Symport Pumps.This type of transport requires the use of energy such as ATP to move the
glucose molecules into the cell.

Which of the following evidence supports the theory of plate tectonics?
The age of rocks and mountains on the edge of neighboring continents varies.
Fossils from the same species are found on only one continent.
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
Grooves created from glacier movement travel in opposite directions on each continent.
The characteristics of the tectonic plates allows to find the result for the correct statement is:
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.
The tectonic plate model establishes that by the hot magma convection currents the solid crust breaks in the weakest areas, forming plates that move floating on this, hot magna that can rise through the cracks and separate these plates.
In the attached we see a diagram of the magnetic alignments in the rocks from a tectonic plate, we can see that the alignment changes due to the inversion of the earth's magnetic field in such a way that we can appreciate the separation of the two plates.
Another proof is that other similar animals are on continents separated by great distances.
Let's analyze the different claims:
a. False. Radioactive dating evidence gives that the rocks give that the rocks on the two continents are the same age.
b. False. Fossils of the same spice are found on several continents.
c. True. These rocks when they emerged were aligned and when moving and the magnetic field reversed the rocks are no longer aligned, this is one of the greatest proof of the separation of tectonic plates.
d. False. The furrows of the glaciers go from the North to the South, it does not have the direction of the displacement of the plates.
In consequence of the characteristics of the tectonic plates we can find the result for the correct statement is:
Iron-rich, molten magma rocks no longer align to Earth’s poles in many locations.

Which of the following best describes sickle-cell anemia?
O Caused by environmental factors that an individual was exposed to during pregnancy.
O A hereditary genetic mutation that causes a resistance to malaria.
O An inherited disorder that increases the risk of contracting malaria from mosquitos.
O A genetic mutation that is inherited from a dominant allele of one parent.
Answer: The answer should be B "O A hereditary genetic mutation that causes a resistance to malaria."
Explanation:
I do FLVS also you can find this out in your lesson 3.04 on page 5.
It says, "Sickle-cell disease is a genetic disorder that gives red blood cells a crescent shape instead of the typical disk shape. Sickle cells are stiff and sticky. They tend to block blood flow in the blood vessels of the limbs and organs. Blocked blood flow can cause pain, serious infections, and organ damage. This genetic disease is recessive, meaning the allele must be inherited from both parents to be expressed in a person’s phenotype. It is caused by a mutation in the gene that produces hemoglobin, the blood’s principle oxygen-carrying protein. Sickle-cell disease occurs more commonly in people and descendants from tropical and subtropical regions where malaria is common. Scientists have discovered that individuals with just one allele for sickle-cell disease are not only healthy, but they actually have a high resistance for the parasite that causes malaria. This resistance gives the carriers of one sickle-cell allele a great advantage over malaria, which claims more than a million lives each year, and explains why the allele for this dangerous genetic disease survives to be passed down to future generations."

The sickle cell gene is inherited and results in sickle cell disease. You cannot catch HPV from an infected person because it is not brought on by whatever the parents did either before or during the pregnancy. Thus, option B is correct.
What are the characteristics of sickle-cell anemia?Red blood cells are typically disc-shaped and sufficiently flexible to pass readily through blood arteries.
Red blood cells with sickle cell disease have a crescent or “sickle” shape. Because sickle cells impede blood flow to particular organs, sickle cell disease complications can develop.
The severe side effects include stroke, acute chest syndrome, organ damage, various disabilities, and even early death. Acute chest syndrome lowers the blood's oxygen content.
Therefore, A hereditary genetic mutation that causes a resistance to malaria.

A hormone signals through a G protein-coupled receptor as shown in the diagram. After the production of IP3, which of these events will MOST quickly stop the transduction of the signal?
A. the hydrolysis of IP3
B. the hydrolysis of GTP
C. the hydrolysis of PIP2
D. the hydrolysis of the hormone
Answer: The answer is A
Explanation: Took the test lol
The quickest halt to the signal transduction process after IP3 production occurs through the hydrolysis of IP3 itself, as option A.
The hydrolysis of IP3 results in the quickest termination of the signal transduction pathway among the available alternatives. A series of actions are triggered by IP3, which causes the release of calcium ions from intracellular reserves. IP3 is hydrolyzed by phosphatases, which halts the calcium release and prevents protracted signaling.
Even while the hydrolysis of GTP and PIP2 is a necessary step in the cessation of G protein-coupled receptor signaling, it happens later and does not have the same rapid effects as IP3 hydrolysis. The hormone's own breakdown is not a known mechanism for halting signal transmission.

Answer:
The cell theory states that all living beings are made of cells. There is a debate as to whether or not viruses should be considered to be alive. The debate results from the fact that viruses cannot reproduce on their own. They must invade a host cell and utilize the host’s genetic material in order to reproduce. Viruses are not true cells. They lack the most important part of the cell, the protoplasm. Hence, the cell theory is not applicable to viruses. Hence, the answer is C.

Explanation:
In order to meet the basic needs of increases population, the present society has under taken a series of steps like rapid industrialization, unplanned urbanisation, deforestation, overexploitation of natural sources, etc.
The outcomes of the above human activities have contributed significantly to the degradation of environment around us.
Some important impacts of human activities on environment are outlined below:
1. Deforestation:
In order to provide timber and farm land to increased population, large number of forest trees are cut and forest area is converting to farm lands. The rate of deforestation is so faster that around 1.5 million hectare of forest cover is lost every year is India alone. The process of deforestation results in decreasing rainfall, increasing global temperature, loss of top soil, modification of climatic conditions etc.
2. Industrialization:
Although the industrial activities of man provide basic need of the society, simultaneously the same release a lot of pollutants to the environment. The pollutants in environment cause loss of raw materials, health hazards, increase in death rate, damage to crop, making environment unfit for living organisms etc.
3. Loss of ecological balance:
The excessive use, misuse and mis-management of biosphere resources results in disturbance in ecosystem or ecological imbalance.
4. Air pollution:
The anthropogenic release of various air pollutants to the environment causes a number of dreaded phenomena like green house effect, ozone layer depletion, acid rain and smog formation etc.
5. Water pollution:
Human activities in respect of disposal of sewage wastes, solid wastes, municipal wastes, agricultural and industrial wastes cause the environment unfit for day to day use. Besides, polluted water spreads or leads to different diseases.
6. Increased consumption of natural resources:
Since the starting of industrial era, the natural resources are constantly utilised for the production of one or more products for the day to day use of society.
7. Production of waste:
Rapid industrialization and unplanned urbanization release a lot of toxic waste material either in solid or liquid or gaseous state which induces a number of serious environmental hazards.
8. Extinction of Wildlife:
Since forests are natural habitats of wild life (both plants and animals) deforestation leads to the extinction of valuable wild life and loss of biodiversity.
9. Habitual destruction:
The commercial and industrial activities associated with mining, construction of dams, fishing, agriculture etc. cause habitat destruction which is a pathway to pollution.
10. Noise pollution:
The man-made noise due to mechanized automobile, industries, trains, aero planes, social functions etc. causes noise pollution which has impact on both biotic and a biotic components of environment.
11. Radiation pollution:
The radiations from radioactive substances used in nuclear reactors and nuclear weapons can have significant impact on genetic materials of body (DMA, RHA etc.)
12. Soil erosion:
The anthropogenic processes like deforestation and overgrazing induce soil erosion which causes soil moisture reduction, lowering of productivity, decline in soil fertility etc.
