What is a truck's acceleration if the net external force on the truck is 560 N and it has a total of mass of 1000 kg?
Answer:
0.56m/s²
Explanation:
The above is the correct answer.
Force = mass x acceleration = mg
⇒ F = mg
where F = 560 N, m = 1000kg
∴ g = F/m = 560/1000 = 0.56
∴ acceleration, g = 0.56m/s² (answer)
Force is known to be a push or a pull which actually puts a body to motion or brings a body to rest. It has to do with the interaction between bodies.
A common genetic mutation that lowers levels of the enzyme cathepsin C severely reduces a person’s ability to ward off periodontitis, or gum disease. The enzyme triggers immunological reactions that destroy diseased cells and eliminate infections
in the mouth. But researchers are developing ways to restore the enzyme to normal levels. Once that happens, we will be able to eliminate periodontitis.
Which one of the following is an assumption on which the argument depends?
(A) Restoring cathepsin C to normal levels is the only way to eliminate periodontitis.
(B) Genetic mutation is the only cause of lowered levels of cathepsin C.
(C) Researchers will soon succeed in finding means of restoring cathepsin C to normal levels.
(D) Persons who do not have the genetic mutation that lowers levels of cathepsin C do not get gum disease.
(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.
Answer:
(E) A person whose cathepsin C level has been restored to normal will not suffer from periodontitis.
Explanation:
Considering the fact that there may be some other causes of periodontitis aside from the lowered levels of the enzyme.
Therefore, should there be some other causes of periodontitis, hence, it can be concluded the process of restoring the enzyme to normal levels might not be sufficient for eliminating periodontitis.
Hence, the author's argument is solely based on this assumption, and option. Hence, option (E) is the correct answer.

What are seasons?A season exists the year that stands determined by particular climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly. Each includes its light, temperature, and weather designs that repeat yearly.
Summer exists the hottest of the four temperate seasons, happening after spring and before autumn. At or centered on the summer solstice, the earlier sunrise and latest sunset happen, daylight hours exist longest and dark hours exist shortest, with day length falling as the season progresses after the solstice.
Winter, the coldest season of the year, between autumn and spring; the name arrives from an old Germanic word that represents “time of water” and guides to the rain and snow of winter in middle and increased latitudes.

Musculo que tiene las características tanto de musculo esquelético como de musculo liso. Se encuentra en el corazón y sus contracciones son involuntarias
Answer:
músculo cardíaco
Explanation:
Los 3 tipos de tejido muscular son 1-músculo cardíaco o miocardio (involuntario), 2-músculo liso (involuntario) y 3-músculo esquelético (voluntario). Las células del músculo cardíaco, las cuales son conocidas como 'miocardiocitos', poseen una apariencia estriada y forman la pared del corazón. Los miocardiocitos son alargados, ramificados, y poseen un núcleo central (son células uninucleadas, a diferencia de las células del músculo esquelético, las cuales son multinucleadas). Además, los micardicitos son más cortos (80 a 100 µm) y más anchos (aprox. 15 µm) que las células del músculo esquelético. Los miocardiocitos presentan uniones especializadas conocidas como discos intercalares, los cuales son un tipo de complejo de unión entre los límites de dos cardiomiocitos. En el citoplasma de los cardiomiocitos se encuentran las miofibrillas, las cuales son estructuras contráctililes que les confieren a las células musculares sus propiedades características de contracción y de elasticidad. En estas células (cardiomiocitos) las miofibrillas se disponen de manera longitudininal con un patrón estriado.

b. diffusion and osmosis across semi-permeable membranes
c. the movement of the flagella of sperm for motility
d. exocytosis of waste substances across a semi-permeable membrane
Answer:
b. diffusion and osmosis across semi-permeable membranes
Explanation:
ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.
In the above options, the processes listed as follows require ATP to occur:
- The active transport of glucose from the small intestine to the blood
- The movement of the flagella of sperm for motility
- Exocytosis of waste substances across a semi-permeable membrane
However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.

Match the surface to its respective albedo score. fresh snow soil ocean (high-angle sun) ocean (low-angle sun) 0.95 arrowRight 0.2 arrowRight 0.9 arrowRight 0.05 arrowRight Reset Next
Answer:
fresh snow → 0.9soil → 0.2ocean (high-angle sun) → 0.05ocean (low-angle sun → 0.95Explanation:
Albedo is the radiation reflected by the earth´s surface to the universe.
Albedo might be defined as a relation between reflected light from a particle and the incident light. It is the fraction of the incident radiation that is reflected by any object. If the surface is mostly clear and clean, most of the incident radiation is reflected. But if the surface is dark and rugose, most of the incident radiation is absorbed, and the temperature of the absorbing object will increase.
Albedo value is always inferior or equal to one and can be expressed as a percentage. The surface that reflects 100% of the incident light will have an albedo value = 1. But if the surface absorbs all the radiation and does not reflect any percentage, the albedo value = 0. Note: there is no real object that might reflect or absorb 100% of the incident radiation.
The importance of albedo is that it avoids high temperatures on the earth. There are many different surfaces with different albedo values. Global variations in albedo are natural processes due to exogenic and endogenic variations. But to these natural events, we must add all the variations caused by human beings´ actions, which increase greenhouse gases, decreasing albedo, and increasing global warming. The increase of greenhouse gases, such as CO₂, decreases albedo. The same occurs with atmospheric dust due to volcanic eruptions. Additional material interposes between the earth´s surface and the universe, decreasing the energy return to the universe.

Why did heating the water affect the surface? I need help my mother is making me di science and im so confused :( I doubt this is biology..
Changes in the surface temperature heat or cool the air above, which leads to air movement (wind). Solar heating of the Earth's surface is uneven because land heats faster than water, and this causes air to warm, expand and rise over land while it cools and sinks over the cooler surfaces.
An individual with two different versions of a gene is genetically ____________ . In traits with a simple pattern of inheritance, only the trait conferred by the ____________ form of the gene will be visible. The other form of the gene is ____________ : it confers a trait that is only visible when the individual is genetically ____________ , or has two identical copies of the gene.
Answer:
heterozygous; dominant; recessive; h.o.mo-zygous
Explanation:
Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.
In Genetics, co-dominance can be defined as a phenomenon in which two (2) alleles of the same gene are present in a living organism and both are equally expressed to a degree or simultaneously.
This ultimately implies that, co-dominance is a phenomenon that typically involves the relationship between alleles i.e the two (2) versions of a gene present in living organisms. Also, a single version of a gene expressed by a living organism is referred to as an allele.
Trait can be defined as a distinguishing quality or characteristic of a living thing.
Simply stated, a trait refers to the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.
Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.
In Genetics, when an individual has two (2) different versions of a gene, he or she is said to be genetically heterozygous.
In traits with a simple pattern of inheritance, only the trait conferred by the dominant form of the gene from the parent organism will be visible in the offspring of a living organism. The other form of the gene is recessive : it confers a trait that is only visible when the individual is genetically , or has two identical copies of the gene.
