3. What is the difference between the environmental impacts of particles, such as dust and

Minchanka [31]

Answer:

Environmental impacts of particles, such as dust and smoke, released from livestock production - impair the visibility, can lead to acid rain, degrade the ecosystem

Environmental impacts of greenhouse gases released from livestock production - increase in atmospheric temperature

Explanation:

Environmental impacts of particles, such as dust and smoke, released from livestock production -

Release of particles such as dust and smoke is referred to as particulate pollution. These particle makes the air unfit for .breathing. If humans inhale it, it will adversely affect the heart and lungs.

These particle impair the visibility, can lead to acid rain, degrade the ecosystem etc.

Environmental impacts of greenhouse gases released from livestock production -

Green house gases will lead to increase in atmospheric temperature

) Consider a pea plant- it has a gene controlling seed color- yellow Vs green; another gene controlling seed texture-smooth Vs w

lana [24]

Answer:

Yellow smooth - 9

Yellow wrinkle - 3

Green smooth- 3

Green Wrinkle - 1

Explanation:

Let the green color of the seed be depicted by "G" and the yellow color of the seed be depicted by "g"

Let the smooth the seed be depicted by "R" and wrinkled seed be depicted by "r"

F1 cross -

true breeding smooth green plant ( RRGG) and true breeding wrinkled yellow (rrgg)

F1 gamete will be RG, RG, rg, rg

F1 offspring will be RrGg , Thus all F1 offspring will be heterozygous smooth and yellow.

Thus, R is dominant over r and g is dominant over G

F2 Generation –

RrGg x RrGg

Gametes will be RG, Rg, rG, rg

RG Rg rG rg

RG RRGG RRGg RrGG RrGg

Rg RRGg RRgg RrGg Rrgg

rG RrGG RrGg rrGG rrGg

rg RrGg Rrgg rrGg rrgg

R is dominant over r and g is dominant over G

Genotypes are –

RRGG - 1 (Smooth Green)

RRGg-2 (Smooth yellow)

RrGG-2 (Smooth Green)

RrGg-4 (Smooth yellow)

RRgg- 1 (smooth yellow)

Rrgg – 2 (Smooth yellow)

rrGG – 1 (wrinkled Green)

rrGg – 2 (Wrinkled yellow)

rrgg – 1 (wrinkled yellow)

Yellow smooth - 9

Yellow wrinkle - 3

Green smooth- 3

Green Wrinkle - 1
