Explanation

Chymosin is an enzyme used as a clotting agent in the production of GMO cheese, helping to coagulate milk.

It is often produced using genetically modified microorganisms to ensure consistent quality and supply.

Explanation

Let's find the common difference (d) of the arithmetic sequence.

Step 1: Write the formula for the nth term

an = a + (n - 1)d

Step 2: Plug in the values

a = 2, n = 6, an = 27

27 = 2 + (6 - 1)d

27 = 2 + 5d

Step 3: Solve for d

25 = 5d

d = 25/5

d = 5

Explanation

The expression is 2x² + 8x + 8. First, factor out 2:

→ 2(x² + 4x + 4)

Now factor the quadratic:

→ x² + 4x + 4 = (x + 2)(x + 2)

So the full factorization is 2(x + 2)(x + 2).

Explanation

The Hubble Space Telescope is designed specifically for research and observation in space.

It captures images and data about stars, galaxies, and other celestial bodies to support astronomical research.

Explanation

This phenomenon is called persistence of sound or auditory memory.

The human ear retains the sensation of a sound for about 0.1 second (1/10) after the sound stops.

Explanation

To find the total surface area (TSA) of the box:

TSA = 2(lb + bh + hl)

Given length (l) = 5 cm, breadth (b) = 2 cm, and height (h) = 3 cm:

TSA = 2(5_2 + 2_3 + 3*5)

= 2(10 + 6 + 15)

= 2(31)

= 62 cm²

Explanation

A simile compares two unlike things using "like" or "as".

"She ran like the wind" compares her speed to the wind using "like", making it a simile.

Explanation

Oil and petrol form a thin layer on the water surface, blocking sunlight from reaching underwater plants.

This layer also restricts the mixing of oxygen from the air into the water, harming aquatic life.

Explanation

An adjective phrase modifies a noun and consists of an adjective along with its modifiers.

In "She had remarkably bright eyes," the phrase "remarkably bright" modifies the noun "eyes," making it an adjective phrase.
