Evaporation of the water is the process that exerts the pull on water molecules that is relayed from leaf to root via cohesion. The pressure of the water present in the leaves becomes less due to evaporation of water. The pressure of water in the roots and lower part of the shoot is high. This gradient of pressure creates a pull on the water molecules present in the roots to move upwards to the leaves to occupy the vacant space. The whole process is called transpiration.

Answer:

The right answers are mentioned in the picture.

A base pair (bp) is the pairing of two nucleobases located on two complementary strands of DNA or RNA. This pairing is carried out by hydrogen bridges. There are four types of nucleic bases: A-T-C-G, these letters Adenine, Thymine, Cytosine, and Guanine. A with T and C with G.

It is also necessary to take into account the antiparallel character of the DNA strands. If a strand is in the 5 '3' direction, its complete strand is in the 3 '5' direction.

The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to
Zinaida [17]

Answer:

The total length will be "10 units". A further explanation is given below.

Explanation:

The given points are:

R(−2, 4)

S(3, 4)

T(3, −1)

On applying the distance formula,

⇒ RS=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

⇒       =\sqrt{(3-(-2))^2+(4-4)^2}

⇒       =\sqrt{(3+2)^2+(0)^2}

⇒       =\sqrt{25}

⇒       =5 \ units

and,

⇒ ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

⇒       =\sqrt{(3-3)^2+(-1-4)^2}

⇒       =\sqrt{0+(-5)^2}

⇒       =5 \ units

Now,

The total trail length will be:

= RS+ST

= 5+5

= 10 \ units

when discussing acids and bases a solution containing a large number of hydroxide ions, by definition, is considered?
PSYCHO15rus [73]
Acids are solutions/substances that tend to break off to make a hydrogen (H+) ion when placed in an aqueous solution; i.e. solution with water as its solvent.

Bases, on the other hand, produce a hydroxide ion (OH-) when placed in an aqueous solution. 

Thus, by definition, we can safely assume that a solution containing a large number of hydroxide ions is considered a base.

If you are unclear about this, or still need help, please feel free to ask me further. Thank you.
