Use the drop-down menus to complete the statements.
Korvikt [17]

Answer:

In the first step of meiosis I, the chromosomes/genetic material of the cell condenses into a visible form, into a form called heterochromatin. The nucleolus also disappears.

In the second step, a process called synapsis occurs. This is when homologous chromosomes align themselves, gene by gene.

In the third step, crossing over occurs. Segments of corresponding DNA are cut and exchanged between non-sister chromatids of the formed tetrads.

In the fourth step, the nucleus fragments, the nuclear envelope fragments, the two centrosomes (if we're talking about an animal cell) separate from each other as their asters and mitotic spindles (mostly microtubules (kinetochore and non-kinetochore) lengthen. The microtubules extending from the centrosomes can now connect to chromosomes.

A bird is flying in the air at a 4 m/s. If the mass of the bird is 7kg what is it’s kinetic energy
yaroslaw [1]

Answer: The kinetic energy of the flying bird is 56 Joules.

Explanation:

Mass of the bird  = 7 kg

Velocity of the flying bird = 4 m/s

Kinetic energy of the bird will be given by :

K.E.=\frac{1}{2}mv^2

K.E.=\frac{1}{2}\times 7 kg\times (4 m/s)^2=56 Joules

The kinetic energy of the flying bird is 56 Joules.
