Explain how baking soda and vinegar is a chemical reaction
Answer:
Explanation:
Baking soda and vinegar react chemically because one is a base and the other is an acid. ... The first reaction is the acid-base reaction. When vinegar and baking soda are first mixed together, hydrogen ions in the vinegar react with the sodium and bicarbonate ions in the baking soda.
As a frog develops from a tadpole into an adult frog, it goes through changes that are signaled by hormones within the body. Which best describes the role hormones play in changing a tadpole to a frog?
Answer: In amphibians, metamorphosis is generally associated with the changes that prepare an aquatic organism for a primarily terrestrial existence In (frogs and toads), the metamorphic changes are more dramatic, and almost every organ is subject to modification Regressive changes include the loss of the tadpole's teeth and internal gills, as well as the destruction of the tail. At the same time, constructive processes such as limb development are also evident. The means of locomotion changes as the paddle tail recedes while the hind limbs and forelimbs develop. The tadpole's cartilaginous skull is replaced by the predominantly bony skull of the frog. The teeth used for tearing pond plants disappear as the mouth and jaw take a new shape, and the tongue muscle develops. Meanwhile, the large intestine characteristic of herbivores shortens to suit the more carnivorous diet of the adult frog. The gills regress, and the gill arches degenerate. The lungs enlarge, and muscles and cartilage develop for pumping air in and out of the lungs. The sensory apparatus changes, too, as the lateral line system of the tadpole degenerates, and the eye and ear undergo further differentiation The middle ear develops, as does the tympanic membrane characteristic of frog and toad outer ears. In the eye, both ingratiating membranes and eyelids emerge.

When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between which two reservoirs of the carbon cycle? * A. Hydrosphere and biosphere B. Geosphere/lithosphere and atmosphere C. Atmosphere and biosphere D. Hydrosphere and geosphere/lithosphere
Answer:
B
Explanation:
When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between the Geosphere/lithosphere and the atmosphere.
Both the geosphere and the atmosphere represent important reservoirs of carbon. The digging-up of fossil fuels, otherwise known as exploration, is carried out in the geosphere or the lithosphere part of the earth. For example, crude oil is obtained deep from the ground. When the fuels are burned, they release carbon in the form of carbon dioxide into the atmosphere.
Hence, it can be concluded that carbon flows from the geosphere/lithosphere part of the earth to the atmospheric portion of the earth when fossil fuels are burned.
The correct option is B.

A scientist is studying a species of mouse living in a field. She observes that the mouse nests are mostly made from cogongrass, a type of grass that is common in the field. After doing some research, she creates the hypothesis that the mice make their nests out of materials that are easy to find.
What would be the scientist's next step in gaining knowledge about how the mice choose their nesting materials?
A.
coming up with more questions about the mice
B.
creating other possible hypotheses about the nests
C.
performing an experiment to test her hypothesis
D.
publishing her hypothesis in a scientific journal
Answer:
B
Explanation:
Creating other possible hypotheses about the nests.
What is Nesting material?
Everything birds may use to build a nest is referred to as "nesting material."
All birds require suitable materials for their nests, regardless of whether they build a straightforward depression out of wood and straw or a more complex nest structure with complicated construction.
Depending on the size of the nest, where it is built, and how it will be utilized in terms of the number of eggs, several broods, and yearly reuse, different birds will use different materials to build their nests.
Several birds gravitate toward fluffy material, such as seeds with silky attachments designed to blow them on the wind or seed pods with a soft, hair-like covering.
Therefore, Creating other possible hypotheses about the nests.

Our Sun has a surface temperature of about 9000 degrees Celsius, and is G2 Star.
Answer:
Sun is classified as a G2 V star, with G2 standing for the second hottest stars of the yellow G class of surface temperature about 5,800 kelvins (K) and the V representing a main sequence, or dwarf, star, the typical star for this temperature class.
Answer:
According to NASA, the sun's temperature ranges from roughly 27 million degrees Fahrenheit (15 million degrees Celsius) in its core to just around 10,000 degrees Fahrenheit (5,500 degrees Celsius) at its surface.
The Sun is classed as a G2 V star, with G2 denoting the second hottest stars in the yellow G class—surface temperatures of roughly 5,800 kelvins (K)—and the V denoting a main sequence, or dwarf, star, which is the most common star in this temperature range.
