Answer:

A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner. Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus.

Answer:

The first principle you need to understand about geologic time is that the laws of nature are always the same. This means that the laws describing how things work are the same today as they were billions of years ago. For example, water freezes at 0°C. This law has always been true and always will be true. Knowing the natural laws helps you think about Earth’s past, because it gives you clues about how things happened very long ago. It means that we can use present-day processes to interpret the past. Imagine you find fossils of sea animals in a rock. The laws of nature say that sea animals must live in the sea. That law has never changed, so the rock must have formed near the sea. The rock may be millions of years old, but the fossils in it are a clue for us today about how it formed.

Now imagine that you find that same rock with fossils of a sea animal in a place that is very dry and nowhere near the sea. How could that be? Remember that the laws of nature never change. Therefore, the fossil means that the rock definitely formed by the sea. This tells you that even though the area is now dry, it must have once been underwater. Clues like this have helped scientists learn that Earth’s surface features have changed many times. Spots that were once covered by warm seas may now be cool and dry. Places that now have tall mountains may have once been low, flat ground. These kinds of changes take place over many millions of years, but they are still slowly going on today. The place where you live right now may look very different in the far future.

The first principle you need to understand about geologic time is that the laws of nature are always the same.

Water, for instance, freezes at 0°C. This rule has held and will continue to hold forever.

Understanding natural principles facilitate historical thinking because it provides hints about how things were very long ago. It implies that we can interpret the past using current methods.

The rock must have formed close to the sea because this law has never changed.

Therefore, The first principle you need to understand about geologic time is that the laws of nature are always the same.

Answer:

Fragments of rock or lava that are sent into the air in a volcanic explosion are called tephra.

Explanation:

The volcanoes come in different shapes and sizes, and with them come different types of eruptions as well. Some volcanoes have explosive eruptions, some mainly release ashes and gasses, while some erupt with lava flows. The volcanoes that have explosive eruptions release a lot of pyroclastic material often propelled high and wide around them.

Part of the pyroclastic material that is released is the tephra. Tephra is basically represented by fragments of very hot rock and lava that are shoot into the air during a volcanic eruption. The tephra is extremely dangerous, as it can be shoot out over a distance of several km, and being very heavy, very hot, and moving at very high speed, when it hits something it manages to destroy it or cause enormous damage, and if it is a living organism that is hot it will mean the end of it for sure.

Answer:

Tephra

Explanation:

Definition: rock fragments and particles ejected by a volcanic eruption.

Answer:

The correct answer is - increase in frequency.

Explanation:

According to the theory of Darwin, organisms most likely survive and reproduce in an ecosystem that is able to change or adapt to the changes in the ecosystem.

According to the modern evolutionary theory that the genes that are responsible for new changes or traits that help a species to reproduce and survive in a particular environment increase in frequency and the genes do not helps decrease in frequency.

Answer:

diffusion, osmosis and facilitated diffusion

Answer:

B. It shows offspring that have the same genes as the parent.

C. It shows asexual reproduction.

Explanation:

Hydra reproduces by budding​ which is kind of asexual reproduction. In budding, a small bud appears on the body of that organism and grow in size with the passage of time and finally detached from the parent body. so no fusion of gametes occurs so no chance of genetic variation. The offspring have the same genes as the parent because it forms from one parent.

Answer: Parasitism, Predator-Prey, Competition

Explanation:

The symbiotic relationship is the relationship in which two distinct species are associated with each other. In the symbiotic relation the species may get harm or benefit of association. Parasitism can be defined as the symbiotic relationship in which one species get harmed and other one receives the benefit. For example, malarial parasite plasmodium derives the nourishment from the host body (human). Predator-prey relationship is also harmful as the predator kills the prey to obtain it as food. Competition is harmful in the sense two or more organisms of the same or different species compete for the same resource, the most dominant receives the resource the inferior organism is either killed or harmed in the fight for resources.

Examples of greenhouses gases are water vapor, carbon dioxide. methane, nitrous oxide and ozone (O3). Lightning produces ozone as does UV light at high altitudes, methane is produced biologically and in volcanoes (but doesn’t last long in the atmosphere). Carbon Dioxide is also produced biologically and in volcanoes. Water vapour is most from ocean evaporation, which is bad news if the Earth gets hotter because that leads to more Water vapour.

Explanation:

You subtract 499-473. That shows how much water is displaced and the volume of the stone. Hope this helps and have a great day!

Frida wants to measure the volume of a stone. The correct volume is B

The volume of the stone is 26 mL.

What is volume?

The initial volume = 473 mL

The final volume = 499 mL.

The final volume   − Initial volume

= 499 −  473

= 26 mL.

Therefore, Frida wants to measure the volume of a stone. The correct volume is B .The volume of the stone is 26 mL.

Adaptations. Deciduous plants handle the lack of water by shedding their leaves, which tend to evaporate water into the air. During cold winter months, most deciduous plants drop their leaves and go dormant. Plants may hold onto dead leaves for insulation, or use deep snow like a blanket to protect against the cold.

Guard cells close openings in the leaves slowing down water loss.

Answer:

True

Explanation:

Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease. So when it is opened the water vapor depletes quicker but when its closed it slows down the process of depletion.
