The correct answer is option D, difficulty of redesigning workable ecosystems
Reason -
The area that was redesigned into an ecosystem actually failed to attract the endangered species of clapper rails in California because of the following two reasons –
a) Failed attempt of restoration of Cord grass ( a tree which is a dominant tree in the nesting habitat of clapper rail) . Even if few such trees were there they could not grow to their full height and thus were incapable of providing adequate nesting cover
b) Due to the lack of predatory insect, some herbivore insect in the ecosystem attacked the green grasses thereby making the nesting inadequate.
<u>Answer</u>: Cystic fibrosis is a genetic disorder that causes thick mucus secretions.
<u>Explanation</u>:
<em>Cystic fibrosis</em> is a genetic disorder caused by mutations in a gene that makes a protein called CFTR (cystic fibrosis transmembrane regulator).
The CFTR protein normally functions as a channel for transport of chloride ions in cells responsible for mucus production.
A person suffering from cystic fibrosis produces abnormal CFTR protein or no CFTR protein at all.
This is the reason that thick, sticky mucus is produced instead of the thin, watery kind.
For you to understand the process we can say that the weak will die. If the animal or organism can't get food or find any it is naturally "selected" to die.So a Cuticle could have evolved like that. Hope tgis is useful
This process helps the necessary areas in the body to get the nutrients the blood carries. this is the curculatory system included with the other systems that creates a type of substance or nutrient the body needs.
<u>There are five groups of factors responsible for the kind, rate and extent of soil development. They are: Climate, organisms, parent material, topography and time. Soil from one place is different from another because of the differences in the influence of these factors.</u>
no They exhibit the highest per capita resource consumption................................... Overpopulation is more common in LDCs, but typically per capita resource consumption is higher in MDCs
