What we eat, and how we move our bodies, effects our blood. How does that end up affecting our other organs in the body
Answers
Answer:
The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.
Answer:
The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.
The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.

The substances did not change into different substances.
Based on the information provided in the question, there is no evidence or indication of any chemical reaction or change in the substances when they were combined in the cup. The question does not mention any observations or effects that would suggest a chemical transformation.
If there were a chemical reaction or change, it would typically be accompanied by observable signs such as color change, gas production, temperature change, or formation of a precipitate. However, since the question does not provide any evidence or observations of such changes, we can conclude that the substances did not undergo any chemical transformation when combined.
It is important to note that without additional information or details about the substances and their behavior, it is not possible to make definitive conclusions. However, based on the given information, the most reasonable conclusion is that the substances remained unchanged when combined in the cup.

Answers
Answer:
Image result for explain how the burning of fossil fuels causes climate change
When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.
Explanation:
Answer:
Correct answer: B). Global climate is changing due to burning of fossil fuels and deforestation.
Forest holds a large amount of carbon, plants are known to absorb carbon dioxide from the atmosphere as they grow, that carbon dioxide is stored in plants in the form of carbon in plant's roots, leaves and in the soil. When trees are cut down, that stored carbon is released in the environment in the form of carbon dioxide, which accounts for approximately 18% of global greenhouse gas emission.
The burning of fossil fuel like coal, petroleum, oil, gas for the energy purpose is one of the major contributors for the rising level of carbon dioxide in the atmosphere, which leads to global warming and affect the climate.
Hence, the correct answer would be option B.

The period of time when sexual intercourse takes place between two organisms is called mating. However, all the matings need not end in fertilization.
The gestation period is a time when the embryo develops completely into a fetus. This is usually from the time of fertilization to the time of giving birth.
Let us take the comparison of the gestation period of 3 mammals.
The gestation period of a cow varies from 279- 287 days. The mating between the bull and cow occurs during the heat or oestrus period of the cow. At that time the bull mounts on the cow or vice-versa may happen during the mating period. This is termed bulling.
In the case of horses, the gestation period is 320-380days. The mating ritual in a horse is a bit different than in a cow. It usually has three phases of sexual behavior which includes: courtship, mating, and post mating behavior. During courtship, the stallion which is the male horse will approach the mare, prance, sniff her, nuzzle her, and groom her. The mare which is the female horse may squeal, kick, or move away to show the stallion that she is not ready. When the mare is receptive to breeding, she may stand still, deviate her tail, and urinate, leading the stallion to mount her. It usually breeds well in pastures than in controlled environmental breeding conditions.
Whereas in camels, the gestation period is far longer than in cows and horses. It is about 360-440days. The male camel displays its organ called a dulla to show out is ready for mating. The male camel Urinates on its own tail and swishes it over its back so that the Urine contains female-attracting pheromones. It shows distinct violent behavior towards other male camels. The female camel undergoes an estrous cycle in the breeding season which lasts receptive for 3-4 days, and non-receptive following the other 10 days. In the receptive period, the camel sits down and exposes its genitalia for the male camel to copulate. The whole mating takes about 20 minutes and is accompanied by gurgling and frothing by the male and bleating by the females.
It should be noted that African elephants have longer gestation periods like Asian elephants whereas no other animal has a longer gestation period than an elephant or a shorter gestation period than mice.

In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answers
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

Answers
The Answer is 0.001156.
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.

What happens to the atoms that make up hydrogen fuel as it burns?
Answers
Answer:
When hydrogen fuel burns, its atoms combine with oxygen atoms in the air, which creates a chemical reaction that releases energy in the form of heat and light. The hydrogen atoms lose their outermost electrons, becoming positively charged ions (protons). These ions combine with the oxygen atoms to form water molecules (H2O), which evaporate into the air as steam. Therefore, the atoms that make up hydrogen fuel ultimately become part of water molecules during the process of combustion.
