<h2>Competitive exclusion principle.</h2>
Explanation:
The fundamental and realized niches of B. balanoides are identical, but the fundamental and realized niches of C. stellatus are different.
All the possible combination of resources and condition under which a species can grow, survive and reproduce is called its fundamental niche. Whereas, the more limited set of resources and condition under which a species can grow, survive and reproduce in the presence of competitors and predators is termed as its realized niche.
Competitive exclusion principle states that if two competing species coexist in a stable, homogeneous environment, then they do so as a result of differentiation in their realized niche.
<em>B. balanoides</em> can use a wider range of resources than<em> C. stellatus </em>because its fundamental and realized niches are identical . Hence thrives to exclude C.stellatus.

X-linked dominant disorders are not very common in females because it has to be on BOTH of their alleles in order to occur phenotypically.
Because you get one chromosome from your mom and another one from your dad, it would be impossible for the daughter to get the disorder because the dad doesn’t have it on his X chromosome to pass on to her.
In the case of the daughter, the focus is whether or not the dad has the disorder, the mom isn’t as relevant. However, if you were talking about a son, it would be a different story.
Hope this helps :)
<span>Water has a pH of 7. If it was 0, it would be a strong acidic acid
Water can dissolve most substances due to its polarity and hydrogen bonds
Water can dissolve minerals due to it polarity and hydrogen bonds
Water expands when it freezes because it it able to create my tetrahedron structures in solid form and this structures are broken and it melts
When water infiltrates something it seeps into the ground and becomes part of the water table.
2, 3, 4 are true. 1 and 5 are false.</span>
About the question:
I failed to find the complete question with the Punnett square, so in the answer and explanation I will propose five options for crosses between dogs with different genotypes, and for each option, I will remark the percent of the offspring that is expected to have wirehair. You just need to look for the option that matches your Punnett Square.
Answer:
- Option 1: HH x HH ----> 100% of the progeny is wire-haired, HH
- Option 2: HH x Hh---> 100% of the progeny is wire-haired, HH + Hh
- Option 3: Hh x Hh --->75% of the progeny is wire-haired, 25% HH + 75% Hh
- Option 4: Hh x hh ---> 50% of the progeny is wire-haired, Hh
- Option 5: hh x hh ----> 0% of the progeny is wire-haired
Explanation:
You will find the complete explanation in the attached files due to technical problems
There are two ways of working out the phylogeny (family tree) of living
animals. One is by analyzing their genes; the other is to analyze the
extent to which they are similar in form. In either case. the results can
then be integrated with the fossil record. In principle, the two
approaches should be complementary. Both should lead to a consistent
account of how snake and lizard families descended from a single stem. More or less a greater number of shared traits would mean they recently diverged from a common ancestor.
