Describe the famous experiment related to gravity that Galileo may have performed. Include the results. Also, state whether the results support the law of gravity. Explain your answer
Answer:
Galileo performed a famous experiment where he used a ball rolling on a ramp (inclined plane) to study the motion of objects under the influence of gravity. The ramp allowed him to make more precise measurements because the ball moved more slowly along the ramp than if it were simply dropped. Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass). Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. Newton took this as his first law of motion. One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him. According to history, Galileo’s experiment on falling bodies largely contributed to Isaac Newton’s Law of Gravity. In Galileo’s experiment, he is said to have dropped balls from the Leaning Tower of Pisa. The balls were made of the same material but had different masses. Galileo set out to prove that the time it took for these objects to reach the ground would be the same. Galileo proved that objects reached the ground at the same time

True or false, the more lean muscle mass, the more responsive your body will be to insulin.
Answer:
True
Explanation:
A general misconception is that insulin is only involved in energy and fat metabolism. When energy needs are high, insulin transports sugar from the blood into the muscle where it can be converted into energy. When energy needs are low, insulin facilitates the conversion of excess sugar into fat where it can be stored for future use.
What is often overlooked is the powerful effect of insulin on stimulating muscle protein growth and repair. An essential action of insulin is to increase the transport into muscle of amino acids, the building blocks of protein, where they can be used for rebuilding and repair. Insulin’s anabolic effects do not end there. Insulin also plays an important role in turning on one of the metabolic switches that control protein synthesis.
This action explains why combinations of carbohydrate and protein are far more effective in stimulating protein synthesis than protein alone. Two switches are responsible for turning on protein synthesis. One is activated by protein, specifically amino acid levels in the blood, and the second by insulin. Consuming carbohydrate (which raises insulin levels) and protein in your recovery drink gives you a dual benefit. In fact, research has shown that a carbohydrate protein drink is 38% more effective than a protein drink in stimulating muscle protein synthesis post exercise.
Another important effect of insulin is inhibition of protein breakdown. At any given time, muscle protein is in a state of flux – it is being synthesized and broken down. When more protein is synthesized than broken down, you have a net gain in lean body mass. After exercise, protein degradation is higher, primarily because during extended endurance activity up to 20% of the working muscle’s energy is derived from protein. That’s why consuming protein in your sports drink offers significant advantages. It reduces the amount of muscle protein used for energy. Higher breakdown rates of protein after exercise increases muscle soreness and slows the overall recovery process. By inhibiting protein breakdown, insulin mediates a faster recovery.
The bottom line – by taking advantage of how and when insulin works and how nutrition can affect insulin activity, endurance athletes can optimize muscle recovery and achieve significant improvements in endurance performance.

1. Clasifica las siguientes sustancias según se trate de nutrientes o productos resultado de la nutrición animal. Razona tu respuesta. residuos orgánicos - alimento - O2 - CO2 2.
Answer:
1. Nutrientes:
- alimento
- oxígeno (O2)
2. Productos de la nutrición animal:
- residuos orgánicos
- dióxido de carbono (CO2)
Explanation:
Los alimentos son sustancias químicas que los animales ingieren a fin de que el organismo transforme dichos compuestos en nutrientes los cuales son requieridos para la generación, el crecimiento y la reconstrucción de células y tejidos.
El oxígeno (O2) es un nutriente escencial para la vida el cual se absorbe mediante el proceso de respiración. Este proceso posibilita la absorción de otros nutrientes obtenidos a través de la alimentación.
Los residuos orgánicos representan productos de la nutrición animal los cuales se descomponen naturalmente para formar parte de la materia orgánica. En animales, los desechos órganicos son eliminados a través de los excrementos o en la orina.
El dióxido de Carbono (CO2) es un producto de la respiración. En animales, la respiración celular consume oxígeno y compuestos orgánicos con el objetivo de producir energía en forma de ATP. Como concecuencia del proceso de respiración, los animales liberan CO2 al medio ambiente.

Which is not a type of plant tissue
A) dermal
B) ground
C) connective
D) vascular
Answer:
C
Explanation:
Plants have only three tissue types: 1) Dermal; 2) Ground; and 3) Vascular. Dermal tissue covers the outer surface of herbaceous plants. Dermal tissue is composed of epidermal cells, closely packed cells that secrete a waxy cuticle that aids in the prevention of water loss.
Connective IS NOT a type of plant tissue (Option C).
Connective tissue is a type of tissue that supports the internal organs in the body of animals.
The dermal plant tissue is a protective layer known as the epidermis.
Xylem and phloem are plant vascular tissues that transport nutrients and waste products in the plant.
Ground plant tissue refers to all the other plant tissue that isn't dermal tissue or vascular tissue.
In conclusion, connective IS NOT a type of plant tissue (Option C).

How many molecules of glucose is needed to undergo cell respiration?
Answer:
One molecule of glucose is needed to produce approximately 38 molecules of ATP in each round of aerobic respiration.
Explanation:
In respiration, organisms use food, or glucose made in photosynthesis to obtain energy. Photosynthesizing organisms use light to synthesize chemical energy.
Mitochondria in some organisms provide the most favorable environment for energy metabolism, glucose undergoes a form of combustion, this results in carbon dioxide and water production, together with energy as ATP or adenosine triphosphate.
C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≅38 ATPglucose+ oxygen → carbon dioxide+ water+ energy
Thus, only one molecule of glucose is needed to produce approximately 38 molecules of ATP.

what are two organisms in the food web that have a predator-prey relationship? i need examples
Answer:
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit. The words "predator" and "prey" are almost always used to mean only animals that eat animals, but the same concept also applies to plants: Bear and berry, rabbit and lettuce, grasshopper and leaf.
Some examples of predator and prey are lion and zebra, bear and fish, and fox and rabbit.
What do you mean by predator-prey relationship?In the predator prey relationship, one species is feeding on the other species. The prey species is the animal being fed on, and the predator is the animal being fed. The predator prey relationship develops over time as many generations of each species interact.
Predator and prey populations cycle through time, as predators decrease numbers of prey. Lack of food resources in turn decrease predator abundance, and the lack of predation pressure allows prey populations to rebound.
The relationships between predators and prey play an important role in structuring ecological communities, with predators influencing the dynamics of their prey in ways that cascade through ecosystems.

Answer:
DNA to DNA: A, T, C, G
DNA to RNA: A, U, C, G
Explanation:
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. In this process, adenine (A) pairs with thymine (T), while cytosine (C) pairs with guanine (G).
Transcription involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand. In this strand, adenine (A) pairs with uracil (U) instead of thymine, but thymine (T) still pairs with adenine (A). Cytosine (C) and guanine (G) still pair to each other.
