Sedimentary rocks form from rock and mineral fragments, and metamorphic rocks form from existing rock.
True
Or False
Answer:
True
Explanation:
Sedimentary - A rock formed as a result of the weathering process, either by compaction and cementation of rock mineral fragments, or the precipitation of dissolved minerals.
Metamorphic - These rocks form as existing rocks are subjected to intense heat and/or pressure, usually over long periods of time.

What is the ratio of the kinetic energy of the car to the kinetic energy of the boat?
A. 2:1
B. 4:1
C. 9:1
D. 16:1
Answer:
B
Explanation:
Kinetic energy is possesed by a body by virtue of its motion. The ratio of the kinetic energy of the car to the boat is 4:1.
What is Kinetic energy?The term kinetic energy refers to the energy that is possesed by a body by virtue of its motion.
Now;
Kinetic energy of the car = 0.5 * 2000 * v^2
Kinetic energy of the boat = 0.5 * 500 * v^2
The ratio of the kinetic energy of the car to that of te boat is; 0.5 * 2000 * v^2/0.5 * 500 * v^2 = 4:1

r If a mouse population changes color from white to black over many generations, which question should be asked to determine whether the population changes are a result of natural selection or artificial selection?
A.
What do humans need to keep mice healthy as pets?
B.
Was there a change in the genetic traits of the mice?
C.
Were the genes of the mice inherited from their parents?
D.
Was there a change in the environment where the mice live?
Answer:
D if there is a change in environment that would favor black fur you could assume that natural selection caused the fur to change
Explanation:
The question which should be asked to determine whether the population changes are a result of natural selection or artificial selection is that was there a change in the environment where the mice live? Thus, the correct option is D.
Natural selection is the process through which the populations of different living organisms adapt and change with respect to their surrounding environment. Individuals in a population are naturally variable, it means that they are all different in some way or the other. This variation in the population means that some individuals have traits which are better suited to the surrounding environment than others.
If a mouse population changes its color from white to black over many generations, then the question which should be asked is "Was there a change in the environment where the mice live?"
Therefore, the correct option is D.

Show different life cycle patterns with the help of near labelled diagram
Answer:
The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.
This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851).
Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar.
Explanation:
Which of the following sentences BEST explains what happens when puddles evaporate?
A. The water absorbs into the ground.
B. The particles of matter move more slowly.
C. The water changes from one form to another.
D. The particles of matter move closer together.
Help
Answer: The correct option is C.
The water changes from one form to another.
Explanation:
This is evaporation is the process water changes from liquid to gas.
Evaporation normally occur in the presence of heat which could be from sun. When puddles are heated, the water present shrink and the water evaporates and changes into vapor or gas. The water changes into gas or gaseous vapor.

CONSIDERAS QUE ES CORRECTO DECIR QUE LOS ANTIBIOTICOS SON MALOS PARA LAS BACTERIAS? Argumenta tu respuesta
Answer:
Sí, ya que su función es matarlas o impedir que aumente el número de estas.
Explanation:
Los antibióticos actúan sobre las bacterias ya sea matandolas o evitando que la población de un determinado tipo de bacterias se reproduzca haciendo que los mecanismos de defensas presentes en nuestro cuerpo puedan actuar sobre las bacterias ya existentes.
Los antibióticos pueden ser específicos para cierto tipo de bacterias o actuar de forma general afectando a varios tipos de bacterias presentes en nuestro organismo. Si se atacan bacterias que están normalmente en nuestro cuerpo por acción indiscriminada del antibiótico, nuestro organismo sufre un desequilibrio ya que las bacterias que tendrían que estar presentes para procesar ciertos elementos o realizar otras funciones no están.

What is one of the main ways that evolution occurs in prokaryotes?
A. Crossing over during DNA replication
B. Exposure to pathogens that change DNA
C. Mutations that occur during binary fission
D. Exchanging DNA during alternation of generations
E. Decomposing dead organisms
Answer:
answer:
the.answer.is.b
B B B
One of the main ways that evolution occurs in prokaryotes is through mutations that occur during binary fission, which is present in Option C. In prokaryotes, which are single-celled organisms that lack a nucleus, evolution occurs primarily through mutations that occur during binary fission.
What is mutation?Prokaryotes, which include bacteria and archaea, are unicellular organisms that lack a nucleus and other membrane-bound organelles. They are known for their remarkable adaptability and ability to evolve rapidly in response to changing environmental conditions, and beneficial mutations that improve an organism's fitness, such as antibiotic resistance, can quickly spread through a population through natural selection.
Hence, one of the main ways that evolution occurs in prokaryotes is through mutations that occur during binary fission, which is present in Option C.
