In watermelons, solid green rind color (G) is dominant to stripes (g).
stiks02 [169]

There are chances of 75% solid green coloured rind in watermelons.

Explanation:

Dominant trait = Solid Green rind G

Recessive trait= stripes g

Given that both the parent plants are heterozygous so their alleles will be

Gg Gg

From the Punnet square

          G        g

G      GG     Gg

g       Gg     gg

The phenotype ratio is 3:1  ( 3 watermelons with the green colour rind and 1 with striped rind observed)

Genotype ratio is 1:2:1

From the observation, we can say that 75% of the watermelons will have solid green colour rind because G is dominant over g.

Part i
evablogger [386]

Answer:

              1. When a rubbed ruler is brought close to the paper, salt and pepper they are not equally attracted as paper is lighter than pepper and salt, so it takes less effort for paper to overcome the force of gravity.

2. electrostatic induction is a phenomenon in which static electricity is generated in an object by bringing an electrically charged object near it. When a charged object is brought near to an uncharged body it causes electrical charges to redistribute in the body, resulting one side having excess of positive charges and other side having negative charges, as a result body become charged.  Electrostatic interaction also depends upon the nature and mass of body.  

b. the combination of fur cloth and rubbed ruler produce greatest effect. The reason is that when ruler is brought near to fur excess of electron will flow into fur.

Define los tipos de proteínas que conforman la membrana
tensa zangetsu [6.8K]

Membrane proteins can be classified into two broad categories—integral (intrinsic) and peripheral (extrinsic)—based on the nature of the membrane-protein interactions (see Figure 3-32). Most biomembranes contain both types of membrane proteins.

Translate:

Las proteínas de membrana se pueden clasificar en dos categorías amplias: integrales (intrínsecas) y periféricas (extrínsecas), según la naturaleza de las interacciones membrana-proteína (véase la figura 3-32). La mayoría de las biomembranas contienen ambos tipos de proteínas de membrana.
