Approximately 30 - 32 molecules of ATP are produced from the complete oxidation of one molecule ofglucose (C6H12O6) in aerobic cellular respiration. Explain reasons why the number of ATP is not knownexactly
One glucose molecule produces 4 ATP, 2 NADH, and 2 pyruvate molecules during glycolysis. Although 4 ATP molecules are produces in the second half, the net gain of glycosis is only 2 ATP because 2 ATP molecules are used in the first half of glycolysis. If the cell cannot catabolize the pyruvate molecules further via the citric acid cycle, it will harvest only 2 ATP molecules from one molecule of glucose.
Glycolysis is the sole source of ATP. If glycolysis is disrupted, the RBC fail their ability to control their Na-K pumps that need ATP to function, and eventually, they die. If the second half of glycolysis slows or stops in the absence of NAD+ or when NAD+ is unavailable, RBC will not produce a sufficient number of ATP in order to survive.
The number of ATP has been estimated between 35 to 30. The total number of ATP is not known exactly due to variance in the degree of coupling between the flow of protons through the ATPase and electron transport ATP which is the energy currency of the cell.

A football player kicks a ball with a mass of 0.42 kg. The average acceleration of the football was 14.8 m/s².
How much force did the kicker supply to the football?
The kicker supply to the football is 6.22 N.
Solution:
F = m*a - A
F = Force = ?
m = mass = 0.42 kg
a = acceleration = 14.8 m/[tex]s^{2}[/tex]
Plug the values in equation A:
F = 0.42 * 14.8
F = 6.216 N
F = 6.22N.
An NFL kicker's foot average force during a kick is about 450 pounds 2002 N and the ball can even deform on contact so kicking is a large power imbalance. A soccer ball is kicked with the power of the leg muscles. Therefore, the forces exerted are muscle forces. Strength is the force produced by using a body part such as an arm or leg. Since there is contact between surfaces, it is the contact force created by muscle activity. This phenomenon is commonly seen in soccer games when a player tries to catch a ball that has been thrown into the air.

what animals have long lifespan and why
One of the features that can make an animal to have a long lifespan is the size, due to the protection conferred by its size. Also, some animals like the elephant and the whale, have a slow cell replication rate, what reduces the risk of cancer, because the less they replicate, the fewer mutations can be caused.
Moreover, many animals have developted many ways of protecting themselves from mutations, such as having several copies of an important gene.
A list of some animals with long lifespan:
- Bowhead whale: potentially 200+ years old.
- Rougheye rockfish: 200+ years old.
- Freshwater pearl mussel: 250+ years old.
- Greenland shark: 272+ years old.
- Tubeworm: 300+ years old.
- Glass sponge: 10,000+ years old.

Albedo is the reflectivity of a surface. Surfaces that are very reflective, have high albedo. Which BEST describes the historical albedo of the earth?
A. More than 50 percent
B. Less than 50 percent
C. Exactly 100 percent
D. Exactly o percent
The correct answer is option B.
When the light hits the Earth, a particular amount of light is reflected back. This reflected rays of light is called albedo.
There are few places through which the light gets reflected and these are the lighter places.
The surface that reflects the most are lighter places like ice and the places that doesn't reflect are the dark places like soil.
The best historical albedo was seen in 1970s. During that period, the reflection was high and also during winters the amount of ice formation was also good.
After that due to the global warming, the percentage went down. Albedo is the reflecting light and if the light isn't trapped then the temperature tends to come down. We can say, the higher the albedo of the surface, the cooler will be the surroundings.
The best percentage of albedo in 1970s was around 30% which was historical albedo of the Earth.

Which kind of signal is produced by the heart cardiacs and triceps of the arm
Answer:
Bones also protect the organs in our bodies. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column. The ribs form a cage that shelters the heart and lungs, and the pelvis helps protect the bladder, part of the intestines, and in women, the reproductive organs.
Explanation:
Bones are made up of a framework of a protein called collagen , with a mineral called calcium phosphate that makes the framework hard and strong. Bones store calcium and release some into the bloodstream when it's needed by other parts of the body. The amounts of certain vitamins and minerals that you eat, especially vitamin D and calcium, directly affect how much calcium is stored in the bones.

Question: Are there any cells we can see with our unaided eyes? Write a Claim: Evidence:Reasoning:
There are many cells we can see with our unaided eyes in the ovum.
The human eye can see objects as small as 100 microns. Objects below 100 microns cannot be seen with the eye. Cells in our bodies are 10 microns in size and cannot be seen with the eye. Eggs, like single cells, can be seen without a microscope. In all mammals, the egg is the only cell visible to the human eye.
Cells are so small that they are usually invisible to the eye. As we age, the vitreous jelly-like substance in the eye liquefies and shrinks. When this happens, the microscopic collagen fibers within the vitreous tend to clump together. This scattered debris cast small shadows on the retina. The smallest object visible to the human eye is approximately 0.1 mm in length.

• What are some different forms of potential energy?
Answer:
chemical, elastic, electrical (electromagnetic), gravitational, nuclear, and thermal energy.
Explanation:
Science is the use of evidence to construct testable explanations and predictions of natural phenomena, as well as the knowledge generated through this process. Lizards with the longest legs are able to climb in order to reach high sources of food and escape the ground when floods or storms occur. Weather conditions for seven years are shown below.How might natural selection act on the lizard population if this pattern continues over time?
Solution:
Note that according to the table, the rainfall increased each year, which will endanger organisms that are above ground and cannot climb. Now, because the longer-legged lizards can climb to reach high food sources and escape from the ground when floods or storms occur, then these members of the population have better characteristics, depending on the environment they are adapted to (lots of rain ). Therefore, according to natural selection, these lizards will probably have a higher survival rate and therefore will be more likely to prevail and their genes to be inherited from generation to generation.

What is the difference between basidium and paraphrase?
Basidium is a microscopic sporangium found in the ascospore of the fruiting body of Basidiomycetes, also known as the tertiary mycelium, which developed from the secondary mycelium. The tertiary mycelium is the highly coiled secondary mycelium.
The presence of a basidiomycete is one of the most important features of basidiomycetes. Basidium usually has four called basidiospores but can have two or eight. In typical basidia, each basidiospore is born at the tip of a thin prong or horn called a sterigma and is forced out upon maturity.
The basidium genius serves as the site of nuclear fusion and meiosis the function at which gametes fuse exchange nuclear material, and divide to reproduce basidiospores. The fungi of the phylum Basidiomycota are easily recognized under the light microscope by the swollen end cells of the hyphae, club-shaped fruiting bodies called singular. Basidium-producing structures are formed by the fusion of two vegetative/somatic cells of different lineages or genotypes.
