Kim and jullio go to a raceway to watch Julio's older brother, Raul compete. Raul's car cover 2.5km in 12 seconds and reaching a speed of 180km/hr.
Let us assume that following:
S=distance
U=initial velocity
V=final velocity
A=acceleration
T=time taken
Given that:-
S=2.5 km
S=2.5×1000 mtr
S=2500 mtr
T=12 seconds
V=180km/hr
=180×1000/3600 m/sec
V=50 mtr/sec
U=0 because in starting his car in rest position
Equation which use for calculations of acceleration,
S = UT + 1/2AT^2
2500 = 0×12 + 1/2A(12)^2
2500 = 0 + 1/2×A×144
2500 = 72×A
A = 2500/72
A = 34.72 m/sec^2
It means when rauls starts the race it's car is in rest position and after that it accelerate at the rate of 34.72 m/sec^2

please help I'm listing my whole file in parts, Explain the different steps involved in cellular respiration. (Focus on glucose and oxygen)
one sentence will do.
Answer:
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.
Explanation:
Energy Storage in Humans Free glucose in blood has 4 kilocalories per gram, 40 kilocalories of energy storage, and a few minutes of life support time. Glycogen has 4 kilocalories per gram, 600 to 1600 kilocalories of energy storage, and 1 day of life support time. Lipids have 9 kilocalories per gram, 100,000 kilocalories of energy storage, and 30 to 40 days of life support time. What is the best conclusion based on this data? Blood is a primary location for energy storage. Fat molecules contain more energy-containing bonds than simple sugars. A gram of glycogen has twice as much energy as a gram of fat. The human body stores approximately 1,000 kcal of glucose.
Answer:
Fat molecules contain more energy-containing bonds than simple sugars.
Explanation:
Lipids are a large group of mostly non-polar hydrophobic hydrocarbons. They include fats and oils, waxes, phospholipids and steroids. They serve many functions in living organisms such as energy storage molecules, information molecules, insulation against cold in some animals etc.
From the information provided above, lipids have 9 kilocalories per gram, 100,000 kilocalories of energy storage, and 30 to 40 days of life support time. When energy provided per gram by lipids is compared with that of either glucose or glycogen, lipids provide more than twice the energy of that of glucose or glycogen. Similarly, the energy storage capacity of lipids over 1000 times that of glucose and 50 times that of glycogen. Therefore, fat molecules (an example of lipids) contain more energy-containing bonds than simple sugars (e.g. glucose)

A student likes to attend football games, no matter how cold and snowy the weather becomes. She is going to a game on a very cold day and takes along a hand warmer. She activates it and tucks it into the glove she is wearing. She holds her hands together, and before long, her hands are warm. Which best describes how her hands were warmed?
a: Heat was transferred by conduction, resulting in an increase in kinetic energy.
b: Heat was transformed by convection, resulting in the conservation of energy
c: Thermal energy was transferred by currents, resulting in an increase in kinetic energy.
d: Heat was transformed by radiation, resulting in an increase in kinetic energy.
Answer:
The correct answer is - a: Heat was transferred by conduction, resulting in an increase in kinetic energy.
Explanation:
Conduction is ne of the het transfer method where particular substance is heated and increase the kinetic energy which leads to the molecules to vibrate more and move or jump to the particles present in neughbouring substance and transfer some part of the enrgy.
This transfer is a continuous process untill both end become of same temperature of have same kinetic energy, In this case, heat is tranfer ffrom hand to gloves and to the other hand which are hold together after activating them.

5. It is winter and everyone in your family has the flu virus but you. Which 10 points
body systems work together to help prevent you from catching the flu?
The cardiovascular system transports the disease fighting cells around the body, the
respiratory system warms the air and weakens the flu virus.
The cardiovascular system transports the disease fighting cells around the body, the
immune system recognizes and kills the pathogen before it can make you sick.
The muscular system creates the disease fighting cells responsible for fighting off
diseases; the excretory system removes pathogens along with liquid waste before it
can make you sick.
The respiratory system warms the air and weakens the flu virus; the immune system
recognizes and kills the pathogen before it can make you sick
Answer:
immune system recognizes and kills the pathogen before it can make you sick
Explanation:
the respiratory and cardiovascular system mostly just spread the disease
the muscular and excretory system have no part in fighting the disease
so the only logical answer left would be the immune system
Which statements describe incomplete dominance? Select three options. Traits are usually dominant. Traits are neither dominant nor recessive. Offspring exhibit an intermediate form of alleles from the parents. Both alleles, one from each parent, are expressed in offspring. Incomplete dominance involves the interaction of two alleles. which ones are right?
Answer:
Traits are neither dominant nor recessive.
Offspring exhibit an intermediate form of alleles from the parents.
Incomplete dominance involves the interaction of two alleles.
Explanation:
In genetics, incomplete dominance (also known as partial dominance) is produced when the dominant allele doesn't mask the effects of the recessive allele, which is also expressed in the phenotype. In consequence, heterozygous organisms for a gene exhibiting incomplete dominance will be a mix (or blend) as a result of the expression of both characters. In humans, for example, Tay-Sachs disease is a genetic disorder characterized by a gene that exhibits incomplete dominance, where heterozygous individuals are still able to produce a key enzyme (hexosaminidase A) due to expression of the wild-type allele, while homo-zygous individuals for Tay Sachs recessive mutation usually die by the age of 4.

Explanation:
A plant's life cycle has two main parts, so it is called the _____.
A.alternation of generations
B.meiosis
C.pollination
D.fertilization
Answer:
A. alternation of generations
Explanation:
Basically, a plant's life cycle has two main parts, namely a diploid and a haploid phase. Since the plant alternates between these two phases in its life cycle, the alternation is typically called the alternation of generations.
Hope this helped!
A. alternation of generations
Alternation of generations (also known as metagenesis) is the type of life cycle that occurs in those plants and algae in the Archaeplastida and the Heterokontophyta that have distinct haploid sexual and diploid asexual stages.
How would the cycle be different if there were no water on earth?
Answer:
What I expect would happen: First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.
Explanation:
The water cycle is the process where water falls as rain, is transported via rivers and streams to lakes and oceans, evaporates into the sky, condenses into clouds, and falls as rain again. Here's a diagram:
water.usgs.gov
water.usgs.gov
So what would happen if there were no condensation stage?
The condensation stage is the one where water vapour gathers together into clouds (and when the clouds become heavy enough with vapour, release water as rain). So the first answer is that there would be no clouds.
Without clouds, I foresee a few things happening:
From clouds come rain. With no clouds, there would be no rain.
Clouds move moisture from lakes and oceans (where it evaporates up) to mountains and other places inland that spark rainfall. And so vast stretches of land would become desert.
Clouds reflect sunlight and help cool the Earth. With no clouds, the average temperature of the Earth would increase significantly.
And so to summarize what I expect would happen. First, there would be no clouds. Lack of clouds would mean there would be no rain and the average temperature of the Earth would increase, resulting in large areas of land becoming desert.

Marine biotechnology can be used to produce genetically modified (GM) fish with preferred traits. Some opponents of genetic modification argue that the release of these fish can have a negative impact on natural ecosystems. Is this a valid concern, and can anything be done to minimize the impact on nature
Incomplete question. The options;
a) yes, gm fish could alter biodiversity if they mate with fish in the wild. This impact is best minimized by producing gm fish that are sterile.
b) yes, gm fish can alter biodiversity if they mate with fish in the wild. This impact is best minimized by tracking the released fish and capturing them.
c) no, gm fish cannot impact natural ecosystems because they are likely to die in the wild. There is no need to be concerned about the impact to nature.
d) no, gm fish cannot impact natural ecosystems because they are designed.
e) there is no need to be concerned about the impact to nature.
Answer:
a) yes, gm fish could alter biodiversity if they mate with fish in the wild. This impact is best minimized by producing gm fish that are sterile.
Explanation:
Indeed, genetically modified (GM) fish basically refers to fish whose natural traits have been edited or adjusted by scientists. For example, they may be modified in such a way that they feed more and grow faster than is usual for wild fish. Biodiversity is altered when these GM fish begin to consume more food and also producing offsprings with similar traits, over time this would make it difficult for natural wild fishes to find food; reducing their population, thereby impacting nature.
However, if GM fish are produced to be sterile (ie cannot reproduce offsprings), it could easily lead to a balance in the population of the natural ecosystem.
The cycling of matter through all of the organisms, populations, and ecosystems of earth
is ultimately powered by what form of energy?
A. Nuclear
B. Light
C. Chemical
D. Kinetic
Answer:
B. Light
Explanation:
The cycling of matter through all of the organisms, populations and ecosystems of the earth is ultimately powered by the light energy from the sun.
All organisms uses the light energy from the sun to derive other forms of energy for their own use.
Light energy is taken into the ecosystem by plants by the process of photosynthesis. During this process, light energy is converted to chemical energy which is stored in organic molecules. This chemical energy is therefore transformed into other forms of energy available in the ecosystem.A new microbe has been discovered in the rumen of sheep. Microscopy shows no evidence of a nuclear membrane and biochemical studies of the cell wall demonstrate the lack of peptidoglycan. Metabolic studies show that this microbe generates methane. This microbe would most likely be classified in ______.
Since it has no nucleus it's most likely a prokaryote
A new microbe discovered in the rumen of sheep that generates methane, shows no evidence of a nuclear membrane, and biochemical studies demonstrate the lack of peptidoglycan. Such type of microbes is likely to be classified in Archaea.
Archaea is a group of single-celled microorganisms that were first discovered in 1977. Archaea are similar to bacteria and eukaryotes, but they are unique in that they thrive in harsh environmental conditions like extreme heat, high salt levels, and acid environments.
Some archaea can also generate methane gas, similar to the microbe in the given description. Hence, the given microbe that generates methane, shows no evidence of a nuclear membrane, and biochemical studies demonstrate the lack of peptidoglycan would most likely be classified in Archaea.

Yeasts are unicellular microorganisms of the fungi kingdom that can digest sugars using both aerobic and anaerobic cellular respiration. In the below experiment, what by-product of this reaction causes the balloons to expand?
Answer:
This question is incomplete as it does not contain the representation of the experiment, however, based on general understanding, the answer is:
Carbon dioxide (CO2)
Explanation:
Yeasts, as stated in this question, are living unicellular organisms that belong to the KINGDOM FUNGI. They employ both the aerobic (with oxygen) and anaerobic respiration (without oxygen) in breaking down sugars. However, both methods of cellular respiration gives off CARBON DIOXIDE (CO2) as a byproduct.
Therefore, when a yeast is placed in a balloon in accordance to this experiment and is allowed to perform respiration either aerobically or anaerobically, it gives off CO2 gas, which causes the balloon to expand.

Very dense particles settle faster than low-density particles.
Large particles are carried away to a new location by ice and glaciers.
Round particles form new landforms more slowly than flat particles do.
Answer:
Very dense particles settle faster than low-density particles.
Explanation:
Erosion is the process of destroying and destroying existing forms in relief.
Erosion is the destruction of the existing structural connections of the rock mass due to the action of exogenous forces and the change of its shape.
The term erosion in the elementary sense should mean changes in the surface layer of the soil relief, which occur as a result of rain, snow, frost, temperature differences, wind, and running water, or due to the work of anthropogenic factors.
