<h2>Answer:</h2>

The substances which cannot be separated are called elements.

<h2>Explanation:</h2>

An element is a type of particle having a similar number of protons in their nuclear cores. For instance, the nuclear number of oxygen is 8, so the component oxygen comprises all iotas which have 8 protons.  

One hundred eighteen elements have been recognized: the initial 94 happen normally on Earth, and the rest 24 are manufactured ones. There are 80 components that have at any rate one stable isotope and 38 that have solely radionuclide, which rot after some time into different components.

In maize (corn), assume that the genes A and B are linked and 30 map units apart. If a plant of Ab/aB is selfed, what proportion
Marat540 [252]

Answer:

2.25%.

Explanation:

The recombination progeny occur due to the crossing over of the homologous chromosomes. The linked gene is 30 map units apart and the recombination frequency is 30.

If a plant of Ab/aB is selfed then the progeny obtained is as follows: Ab – parental – 35%, aB – parental – 35%, AB – recombinant – 15%  and ab – recombinant – 15%. The cross between the F2 progeny with aabb is ( 0.15 × 0.15) = 0.0225 or 2.25%.

Thus, the answer is option (A).

Is extensive loss of hair observed in humans and whales an example of homoplasy or homology? see section 25.1 (page 497) ?
marin [14]
I believe that hair and limbs are homology because all mammals have hair and similar limb structure. Hair loss and social behavior on the other hand are homolasy because not all mammals have them. Homology is the similar traits due to common ancestry while homoplasy is similar traits for other reasons other than common ancestry.
