A collection of stars, dust, and gas bound together by gravity is called galaxy.
What is galaxy?A galaxy is a collection of stars, dust, and gas bound together by gravity. Galaxies vary in size and shape, and can contain anywhere from a few hundred million to trillions of stars. They also contain other celestial objects such as planets, asteroids, comets, and nebulas. The Milky Way, in which our solar system is a part of, is an example of a galaxy.
A universe is the entirety of everything that exists, including all matter, energy, space, and time, including all galaxies, stars, and all other forms of matter and energy.
A solar system is a group of celestial bodies that orbit around a star, including planets, moons, comets, and asteroids. The sun and all the objects that orbit it, including Earth, are part of the solar system.
A planet is a celestial body that orbits around a star, is spherical in shape and has cleared its orbit of other debris. They do not emit light and heat like stars do, but rather, reflect the light and heat of their host star.

Which of the following is NOT a form of active transport?
A) cyclosis
B) phagocytosis
C) diffusion
D) pinocytosis
Answer:
B) phagocytosis.
Explanation:
Phagocytosis is a process in which a cell attaches to the element it wishes to enclose on the exterior of the cell and attracts the item within as it encloses it. Phagocytosis is commonly done when the cell, such as a virus or an infected cell, is attempted to destroy things and often is employed by immune cells.
This is quite particular and dependent on the cell being able to bind to an article it wishes to ingest via cell surface receivers.
Phagocytoses differs from other techniques of endocytism. Unless the cell comes in direct contact with the particle it wishes to ingest, Phagocytosis will not occur.
Diffusion is a type of passive transport. It occurs when molecules transfer passively from high concentration to low concentration zones. So, option c is right.
Active transport involves using energy to move molecules across a membrane against a concentration gradient.
Pinocytosis and phagocytosis are both types of endocytosis. Cytosis is the movement of cytoplasm within a cell. Both are examples of active transport since they both require energy.
Diffusion is the passive movement of molecules from a region of high concentration to a region of low concentration across a cell membrane. It's an example of passive transport not active transport.
Therefore, Diffusion is the only option that is not an active transport mechanism. Thus, option C is correct.

Scientists can produce many plants in the lab by cloning; culturing a few plant cells in a test tube of chemical medium. Few cells grow into a new plant. It is easy for scientists to produce many plants from just a few cells. Where would you add "cloning" to the Venn diagr
Answer:
in the epicenter
Explanation:
In a Venn Diagram that compares and contrasts the different characteristics or features of the produced plants, "cloning" would be in the epicenter. This is because through the process of "cloning" you are basically copying the core genetic makeup of the plant and creating a brand new plant that shares all of the exact same characteristics and features as the plant's whose genetic makeup was used as a baseline.

Answer:
b lake your welcome
Explanation:
because lakes have trees that create the fresh water for the fishes to swim in i think?
An example of a freshwater wetland body is a lake. Thus, the correct option is B.
What is a lake?A freshwater wetland is a waterbody which is supplied with water from all the nearby streams and rivers. Freshwater wetlands are the ecosystems which are affected by the permanent or temporary inundation.
A lake is a naturally occurring, relatively very large body of water which is localized in a basin that is surrounded by land, with much slower-moving flow than that of any inflow or outflow streams that serve to feed or drain the lake. Lakes lie completely on the lands and are separate from that of the ocean, however like the much larger oceans, they also form a part of the Earth's water cycle by serving as many large standing water reservoirs as possible. Most of the lakes are freshwater, however some are salt lakes with salinities even higher than that of the seawater.
Therefore, the correct option is B.

Match each example of irony with the type of irony it represents.
1. The reader knows that the boy is about to break up with his girlfriend, but the girlfriend doesn't know.
Dramatic irony
2. Dave's blood pressure medicine game him a heart attack.
Situational irony
3. "Oh, great! I'm so glad it's raining, and I forgot my umbrella."
Verbal irony
ok so...
1. The reader knows that the boy is about to break up with his girlfriend, but the girlfriend doesn't know. That is dramatic irony
because Dramatic Irony appears when the readers know something the character does not know. For example, in scary stories, the reader often knows where the bad guy hides, but the character does not. As the character approaches the hiding spot, the readers may experience heightened suspense due to the dramatic irony.
2.Dave's blood pressure medicine game him a heart attack. That is
Situational irony.
Situational Irony happens when something happens that the reader does not expect to happen. For example, if someone robs a thief in a story, that portrays situational irony. Readers would not expect a thief who robs others to be the one who gets robbed.
3. "Oh, great! I'm so glad it's raining, and I forgot my umbrella." That is Verbal irony
Verbal Irony occurs when a character says one thing but means something else. This type of irony is also known as sarcasm. For example, a parent might reveal verbal irony, or sarcasm, by showing up at the door of an extremely messy room and commenting, "I've never seen your room this clean before! You are grounded." Clearly, the parent revealed sarcasm when commenting about the cleanliness of the room.

The mid-oceanic ridges is a place located in the Atlantic ocean is know for the concept of seafloor spreading. New seafloor is being created on another side of the ridge.
The diagram or illustration represents the mid-Atlantic ridge which is the zone of upwelling of magma. As the magma upwells it gets deposited on both sides. According to paleomagnetism the magma on both left and right sides leads to the creation of plate tectonics. Hence more close they form the more recent or younger rocks/plates as compared to those formed farther away near the continental mass.Thus the correct option is A.
