When ice freezes, the water around it becomes saltier and colder. _______, it's density increases.

A Therefore
B On the other hand
С In contrast
D Especially

Answers

Answer A seems like the best choice for this question. Just think about some of the synonyms for therefore—”hence,” “consequently,” and “thus.” Because the adverb therefore often plays the role of a conjunction, it's sometimes called a conjunctive adverb.

B isn’t the correct answer to this question because you use “On the other hand” to introduce two contrasting points, facts, or ways of looking at something.

C isn’t the correct answer because we are not comparing or contrasting anything in this sentence.

D isn’t the correct answer because “Especially” is used in a formal sentence example: She can't be sure she will win, especially at this early stage of the campaign.

When ice freezes, the water around it becomes more saline and colder. Therefore, its density increases. Hence, the correct option is (A).

What is Density?

Density is defined as the mass per unit volume of a substance and is denoted by ρ, although the Latin letter D may also be used.

Density is defined as mass divided by volume: [tex]{\displaystyle \rho ={\frac {m}{V}}}[/tex]

where ρ is density, m is mass, and V is volume. It has the units of mass divided by volume such as grams per centimeters cube [tex](g/cm^3)[/tex] or kilograms per liter (kg/l).

When water changes from a liquid to a solid state that is liquid in the form of ice, its density will increase as it becomes saltier and colder.

Thus, when ice freezes, the water around it becomes more saline and colder. Therefore, its density increases. Hence, the correct option is (A).

The harmless scarlet king snake and the venomous eastern coral snake have similar band patterns
and are the same color and size. For the scarlet king snake, the adaptation of having a banding
pattern like the eastern coral snake's is known as mimicry.
The outcome of this adaptation in the scarlet king snake is to -
A. Protect the scarlet king snake from its predators
B. Allow the scarlet king snake to interbreed with other snake
C. Make it easier for the scarlet king snake to attract prey
D. Allow the scarlet king snake to blend in with its environment

Answers

Answer: A. Protect the scarlet king snake from its predators

Explanation: Good luck! :D

Protect the scarlet king snake from its predators. Therefore, option (B) is correct.

What is adaptation?

The adaptation of mimicry in the scarlet king snake allows it to resemble the venomous eastern coral snake, which predators may recognize as a warning signal to stay away. This is known as Batesian mimicry, where a harmless species evolves to resemble a dangerous or unpalatable species as a means of protection.

By mimicking the appearance of the venomous coral snake, the scarlet king snake gains protection from predators that have learned to avoid the coral snake due to its venomous nature. Therefore, the outcome of this adaptation in the scarlet king snake is to protect it from its predators.

The energy from the sun is produced in the core through the process of nuclear fusion. The photons travel through the sun and are released as radiation which travels to the earth. How long does it take to reach the earth?

Answers

Answer:

8 min 20 seconds

Explanation:

Radiation from the sun travels as light through the vacuum of space. Therefore, it is travelling at the speed of light which is roughly 300,000 km/s. If we divide this speed by the average distance between the Sun and the Earth (150,000,000 km) we would get a total of 500 seconds. We can now turn this total time into minutes which would be roughly 8 min and 20 seconds. Therefore, it would take a total of 8 min 20 seconds for radiation from the Sun to reach Earth.

22 Y cuando se cumplieron los días de la purificación de ella, conforme a la ley de Moisés, le trajeron a Jerusalén para presentarlo al Señor

23 (como está escrito en la ley del Señor: Todo varón que abra la matriz será llamado santo para el Señor),

24 y para dar la ofrenda conforme a lo que está dicho en la ley del Señor: un par de tórtolas o dos pichones.

25 Y he aquí, había un hombre en Jerusalén llamado Simeón, y este hombre, justo y piadoso, esperaba la consolación de Israel; y el Espíritu Santo estaba sobre él.

26 Y había recibido revelación del Espíritu Santo que no vería la muerte antes que viese al Cristo del Señor.

27 Y movido por el Espíritu, vino al templo. Y cuando los padres llevaron al niño Jesús al templo, para hacer por él conforme a la costumbre de la ley,

28 entonces él lo tomó en sus brazos, y bendijo a Dios y dijo:

29 Ahora, Señor, despides a tu siervo en paz,conforme a tu palabra,

30 porque han visto mis ojos tu salvación,

31 la cual has preparado en presencia de todos los pueblos;

32 luz para revelación a los gentilesy gloria de tu pueblo Israel.

33 Y José y su madre estaban maravillados de las cosas que se decían de él.

34 Y los bendijo Simeón y dijo a su madre María: He aquí, este niño ha sido puesto para caída y para levantamiento de muchos en Israel, y para señal que será contradicha;

35 y una espada traspasará tu alma misma, para que sean revelados los pensamientos de muchos corazones.

36 Estaba también allí Ana, profetisa, hija de Fanuel, de la tribu de Aser, de edad muy avanzada, y había vivido con su marido siete años desde su virginidad;

37 y era viuda hacía ochenta y cuatro años, y no se apartaba del templo, sirviendo de noche y de día con ayunos y oraciones.

38 Y esta, llegando en la misma hora, daba gracias al Señor y hablaba del niño a todos los que esperaban la redención en Jerusalén.
