A karyotype is used to track the occurrence of a trait in a family

Answer:

False

Explanation:

A karyotype is the collection of all the chromosomes in an individual. Chromosomes can be isolated from cells and visualised by microscopy following the use of a stain to highlight the structural features of the chromosomes.

Karyotyping is used to assess structural or numerical aberrations in chromosomes that could cause genetic disease. For example is is often used to look for Down's syndrome, Turner's syndrome, or Cri du chat syndrome.

To track the occurrence of a trait in a family, a pedigree analysis is used. This is where the family tree is drawn out and individuals with a trait are marked in order to assess the prevalence of the trait in the family, and track it through generations.

Can you solve it descriptively . thanks

Answer:

|M_y| = 170.82 \ N.mm

Explanation:

From the diagram affixed below completes the question

Now from the diagram; We need to resolve the force at point  A into (3) components ; i.e x.y. & z directions which are equivalent to F_x \ , F_y \ ,  F_z

So;

F_x = positive x axis

F_y = Negative y axis

F_z = positive z axis

Then;

|M_x| = F_y *27-F_z*11 = 77 ----- equation(1) \\ \\ |M_z| = F_y*4 - F_x*11 = 81 ---- equation (2) \\ \\ |M_y| = F_x *27 - F_z *4 = ?  ---- equation (3)

From equation (1); Let's make F_y the subject of the formula ; then :

F_y = \frac{77+11F_z}{27}

Substituting  the value for F_y into equation (2) ; we have:

(\frac{77+11F_z}{27})4-F_x*11=81 \\ \\ 11(\frac{7+F_z}{27} ) 4- F_x -11 =81 \\ \\ 28+4 F_z - 27F_x = \frac{81*27}{11} \\ \\ 4F_z - 27F_x = 198.82 -28 \\ \\ 4F_z - 27F_x = 170.82 \\ \\ Since  \ |M_y| = 4F_z-27F_x \\ \\ Then: \\ \\ \\ |M_y| = 170.82 \ N.mm

How far does a 1,300-kg race car travel if it accelerates from rest at a rate of 14 m/s/s for 10
muminat

Answer:

700 m

Explanation:

Given:

v₀ = 0 m/s

a = 14 m/s²

t = 10 s

Find: Δx

Δx = v₀ t + ½ at²

Δx = (0 m/s) (10 s) + ½ (14 m/s²) (10 s)²

Δx = 700 m
