If a Cod Fish Parent has 82 Chromosomes in its Body Cells, how many

Chemistry

MakcuM [25]3 years ago

7 0

Answer:

41 chromosomes each

Explanation:

Meiosis is the means by which sexually-reproducing organisms produce gametes /sex cells used during reproduction. Meiosis is a kind of cell division that results in daughter cells (gametes) with a reduced number of chromosomes (by half). This means that meiosis reduces the chromosomal number of parents cell in the gametes.

Based on this, if a cod fish that possesses 82 chromosomes in Its somatic or body cells undergo meiotic division in order to produce gametes. The chromosome number of the sex cells will be reduced by half i.e. from 82 chromosomes (diploid, 2n) to 41 chromosomes (haploid, n)

Four springs are stretched to the same distance from the equilibrium position. The spring constants are listed in the table. A 2

svp [43]

Answer:

The correct option is;

X, W, Y, Z

Explanation:

The parameters given are;

Spring (S), Spring Constant (N/m)

W, 24

X, 35

Y, 22

Z, 15

The equation for elastic potential energy, $E_e$ , is $E_e = 0.5 \times k \times x^2$

The above equation can also be written as $E_e =\dfrac{1}{2} \times k \times x^2$

Where:

k = The spring constant in (N/m)

x = The spring extension

Therefore, since the elastic potential energy, $E_e$ , of the spring is directly proportional to the spring constant, k, we have the springs with higher spring constant will have higher elastic potential energy, $E_e$ , therefore the correct order is as follows;

X > W > Y > Z
