Answer:

Commensalism

Explanation:

Commensalism is when one organism benefits and the other doesn't benefit and is also not harmed. The tree is helping the orchid and the orchid isn't benefiting or harming the tree.

When a singly ionized potassium ion moves through a channel in the membrane passing from the outside to the inside, what is the
Korolek [52]

The magnitude of the work done by the electric field of the membrane is <u>W = 1.28 × 10⁻²⁰ Joules</u>.

We start with the necessity to take into account a value for the voltage present there in order to solve this problem by first considering that the membranes have two layers, one internal and one external, each responsible for producing a potential difference between the two levels.

As a result, in order to find a solution, it is necessary to take into account the potential difference between the two surfaces. In this instance, we'll assume a particular value for the load, but the recipient is free to substitute a different value if they prefer.

The product of the potential difference and the charge is used to define the work that an electric field performs. The charge of the potassium ion will be equal to that of its electron, so,

q = 1.6 × 10⁻¹⁹ Coulombs

Then the Work would be:

W = Vq

Here,

v = Potential difference

q = Charge

The 80mV potential difference we will have is quantified as follows:

W = (80mV (1V/1000mV))( 1.6 × 10⁻¹⁹ C)

W = 1.28 × 10⁻²⁰ Joules is the amount of work that the membrane's electric field has produced.

m_a_m_a [10]

Answer:

12 : 3 : 1

Explanation:

According to Mendel's principles, a dihybrid cross between two heterozygous summer squash parents (WwGg X WwGg) should yield offsprings, 12 with white, 3 with yellow and  1 with green color phenotype. The classic Mendelian phenotypic ratio for dihybrid cross is 9:3:3:1. In this case, genotypes W- G- and W- gg produce white color phenotype. This is because we have 12: 3: 1 phenotypic ratio in which the alleles of two different genes assort independently into gametes.

<em>Dihybrid cross for heterozygous summer squash:</em>

                    WG         Wg            wG            wg          

    WG      WWGG   WWGg     WwGG     WwGg

    Wg       WWGg   WWgg     WwGg      Wwgg

    wG        WwGG    WwGg     wwGG      wwGg

      wg       WwGg    Wwgg     wwGg        wwgg

   Genotypes:

   W-G-  and W- gg  = white = 12

    ww G- = yellow = 3

     ww gg = green = 1
