What type of rock is formed when hot lava is cool and hardened

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.

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.

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.

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

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.

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.

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.

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.
