If a substance can be separated by physical means and it is not the same throughout, what is it? a heterogeneous mixture a homog

GenaCL600 [577]

<h2>answer:</h2>

a heterogeneous mixture

<h2>explanation:</h2>

A heterogeneous mixture is commonly any mixture that is not uniform in combination - it's a non-uniform mixture of smaller fundamental particles. Using different means, the particles in the mixture can be separated from one another. In a heterogeneous mixture, the elements do not mix completely, and the individual items that form the mixture can be identified. Heterogeneous mixtures can typically be separated back into their original components by chemical or physical means.

The phenomenon of multiple, overlapping action potentials gradually building muscle tension is called:

rewona [7]

The answer is graded potential<span>. Its made of various action potentials that depolarise the neuron incrementaly, in short interspersed intervals that do not give time for the neurons to return to resting potential. Therefore, the actions potentials, of varying sizes, grade up in sum and when they cumulatively reach the threshold level, they invoke an impulse in the nerve</span>

A gene for the MN blood group has codominant alleles M and N. If both children are of blood type M, which of the following is po

fgiga [73]

Answer:

The correct answer would be "Each parent is either M or MN".

Co-dominance is the condition in which both the alleles express themselves completely when present in the heterozygous condition.

The blood group of the offspring can be of M type in two conditions:

1. When both the parents are of M blood group

2. When both the parents are heterozygous for the blood group that is, they both are MN.
