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

Which chromosomal defect is caused when part of a chromosome breaks off and reattaches backward on the same chromosome?
LiRa [457]

The right answer is inversion.

Inversion is a genetic mutation characterized by the end-to-end reversal of a portion of chromatid on a chromosome.

In other words, it is a double break then it is replaced after rotation of 180 ° of a chromosome segment (backward insertion).

We distinguish :

Paracentric inversions:  The centromere in the chromosome is not included in the inversion.

Pericentric inversions:  The centromere is included in the inversion which transforms a metacentric chromosome into an acrocentric chromosome.
