Disparities in mate attraction that alone account for differences in reproductive success An important aspect of evolutionary biology is sexual selection. The nature and scope of sexual selection, however, have been debatable since Darwin first proposed the idea of it.

Recent debate has brought the fundamental topic of what sexual selection actually is back into focus. Incorporating female-female reproductive rivalry into sexual or natural selection is one example of this.

Sex roles are determined by differences in gametes: men generate significantly more plentiful, smaller, motile gametes whereas females produce relatively fewer, more nutritious, often non-motile gametes. There will be an excess of male gametes that will not fertilize any eggs since just one gamete of each kind is necessary to generate a child.

Iron reacts with atmospheric oxygen to form iron oxide or ferric oxide. Look at the chemical equation for this reaction:
kondaur [170]

Answer:

4 Fe + 3 O₂ → 2 Fe₂O₃

Explanation:

Let's start with the oxygen.

Reactants - 2

Products - 3

What number do 2 and 3 have in common? 6.

Put a 3 in the reactants and a 2 in the products to balance the oxygen.

Fe + 3 O₂ → 2 Fe₂O₃

Now let's look at the iron.

Reactants - 1

Products - 4

Put a 4 in the reactants to balance the iron.

4 Fe + 3 O₂ → 2 Fe₂O₃

The equation is balanced. Hope that helps.

There are two different species of finch that live on the same small island, species A andspecies
frosja888 [35]

On the islands of the Galapagos lives a group of birds called finches. There are 13 species in this group. These species have diverse ecologies--some eat seeds, some eat insects, some eat fruit, and some even eat cactus. Although the bodies of these species look fairly similar, their beaks are very different. That is because it is their beak that is adapted to these diverse ways of feeding (Figure 8.14).
