Answer:
Oxygen
Explanation:
Reactants are used to make the products.
The cellular respiration formula is:
oxygen+glucose--> ATP + water +carbon dioxide
The reactants are oxygen and glucose. The products are ATP, water and carbon dioxide.
The gas reactant is oxygen.
Hope this helps! :)
Answer:
Strisores — nightjars, frogmouths, and other nocturnal birds, along with diurnal swifts and hummingbirds.
Columbaves — turacos, bustards, cuckoos, pigeons, sandgrouse, and mesites.
Gruiformes — cranes, rails, crakes, Sungrebe, flufftails, and others.
Aequorlitornithes — shorebirds, flamingos, grebes, gulls, tropicbirds, penguins, and other waterbirds.
Explanation:
1. Placental mammals are those mammals who pregnancy forms in the womb of the mother and forming a placenta between the embryo and the lining of the uterus. This is unlike other categories called marsupials and monotremes that raise their offspring on a pouch and lay eggs respectively.
2. The human's female reproductive duct is composed of the ovaries that release eggs regularly and fallopian tubes that connect the ovaries and the uterus. These eggs travel through the fallopian tube and get to the uterus. The uterus then descended and narrows down into the vagina.
3. The male reproductive system is composed of the testes that produce sperm (they are formed in the epididymis). The sperm travels through the epididymis and through the duct of the penis. The male reproductive system is mostly found ‘outside’ of the body, unlike the female’s.
4. The zygote is formed when a sperm and an egg meet and fuse. This process is called fertilization. The sperm and egg are haploid and fuse to form a diploid zygote. The zygote begins to divide to develops into an embryo.
Answer:
Lets be clear, in an inertial frame of reference it will take 1 newton to move 1 kilogram 1 meter in one second(roughly). 1 joule in that newton, 1/speed of light = incremental mass increase( irrelevant) . So, to move 1 kg of mass 1 meter in 0.00000003 seconds would take 300,000,000 joules(fun).
That divided by speed of light again and your 1kg mass is now 2 kg. Now to move 2 kg 1 meter would take more energy than previously. More energy (newtons) the more relativistic mass gained and thus more energy required to move faster. This is why we cant reach the speed of light - infinite energy. ( again irrelevent to the Question).
But in your question you said lift. Lift is a term that I would find on earth, in a gravity well, so moving that same 1kg of mass wouldn't take 1 newton because the gravitational force pulls the mass down, causing a force called weight - this would be 9.8 N x Mass at sea level. So to lift this 1kg mass will take more than 9.8 N. 10 newtons of life would create a net force of 0.2 N so 0.2/1 = 0.2 meters acceleration.
Note that, gravitational force is one side of the same coin, with acceleration on the other. We talk of gravitation in terms of acceleration, as two masses that are not identical will always fall at the same acceleration. Gravity isn't a force, its a four dimensional field that curves linear paths toward attracting bodies - this is how we are able to orbit objects in space.
Ptolemy was an astronomer and mathematician. He believed that the Earth was the center of the Universe. The word for earth in Greek is geo, so we call this idea a "geocentric" theory.With the development of the heliocentric model by Nicolaus Copernicus in the 16th century, the Sun was believed to be the center of the Universe, with the planets (including Earth) and stars orbiting it.
