Answer:

m=(y2-y1)/(x2-x1)

m=(2-0)/(0-(-2))

m=2/(0+2)

m=2/2

m=1 ==> Gradient of graph

x-int: (-2, 0)

y-int: (0, 2)

Explanation:

m=(y2-y1)/(x2-x1)

m=(2-0)/(0-(-2))

m=2/(0+2)

m=2/2

m=1 ==> Gradient of graph

x-int: (-2, 0) ==> When y=0

y-int: (0, 2) ==> When x=0

Design an experiment that answers this question: "how is stomach acid neutralized in the small intestine?"
Lelechka [254]
The stomach normally secretes acid that is essential in the digestive process and this helps in the breaking down of food during digestion. Acidity is responsible for ulcer, dyspepsia, heartburn and the formulation of the ulcer. One way to experiment on how the acid is neutralized is by using vinegar and starch.

What is the correct sentence?
lorasvet [3.4K]

Answer: The correct sequence in the expression of a trait is gene > protein > trait (Option B).

Explanation:

During gene transcription, a linear fragment of DNA referred to as a 'gene' is used as template to synthesize a complementary messenger RNA (mRNA) sequence.

Subsequently, this mRNA is then used as template to create a protein by a process called translation.

Moreover, phenotypic traits can be defined as all observable characteristics that an organism has.

The phenotypic traits are largely determined by the expression of either enzymatic or structural proteins, which interact to shape the phenotype of an organism.

In conclusion, the correct sequence in the expression of a trait is gene > protein > trait (Option B).
