Do all eukaryotic cells contain a cell wall
romanna [79]

Many kinds of prokaryotes and eukaryotes contain a structure outside the cell membrane called the cell wall. With only a few exceptions, all prokaryotes have thick, rigid cell walls that give them their shape. Among the eukaryotes, some protists, and all fungi and plants, have cell walls.

What is the probability that the first offspring from the cross listed below will be heterozygous for all loci?
Tanya [424]

Answer and Explanation:

<u>Cross:</u> aa Bb dd Ee x AA bb Dd Ee

We can calculate the probability of getting heterozygous individuals in the progeny by using the <u>product rule</u>. Assuming that these four genes <u>assort independently</u> (<em>events that occur independently from each other</em>), we can infer that the F1 will have the next genotypic proportions for each gene:

1) aa     x     AA

F1) 4/4=1 Aa

2) Bb    x    bb

F1) ½ bb

     ½ Bb

3) dd    x    Dd

F1) ½ dd

     ½ Dd

4) Ee    x    Ee

F1) ¼ EE

    2/4 = ½ Ee

     ¼ ee

So, to know what the probability is that the F1 of being heterozygous for all loci, we must multiply the respective individual probabilities of getting a heterozygous genotype, like this:  

1 Aa   x   ½ Bb   x    ½ Dd    x    ½ Ee = 1/8 AaBbDdEe

wel

<em>Answer:</em>

<em>modulate abiotic forces that, in turn, affect resource use by other organisms.  both negative and positive effects on species richness and abundances at small scales, but things that a tree does than directly use the tree for ... changes in biotic or abiotic materials. in comparison to some of the other examples we discuss.</em>

The scales shown in the introduction measure mass,or the amount of matter in a particular object.The scientific law of conservat
Strike441 [17]

The simulation supports the scientific law : I.e TRUE

<h3>The scientific law of conservation of mass</h3>

The scientific law of conservation of mass states that the mass of a substance remains the same in a closed system  as the substance/matter undergoes a chemical reaction. during chemical reaction the matter changes from one form to another. Therefore measuring the mass of matter in an object before it undergoes a chemical reaction support the scientific law as the mass of reactants is equal to mass of product.

Hence we can conclude that the simulation supports the scientific law : I.e TRUE.
