Mucous membrane, membrane lining body cavities and canals that lead to the outside, chiefly the respiratory, digestive, and urogenital tracts. Mucous membranes line many tracts and structures of the body, including the mouth, nose, eyelids, trachea (windpipe) and lungs, stomach and intestines, and the ureters, urethra, and urinary bladder.

Color in McIver beetles is determined by two alleles at one gene locus. McIver beetles must have a heterzygous genotype (genotyp
seraphim [82]

Answer: The frequency of brown beetles is 0.32.

Explanation: The frequency of A1 allele is 0.8. As p+q=1, or the sum of dominant and recessive frequencies equals 1 or 100%:

1 - 0.8 = 0.2

In Hardy-Weinberg principle,

p^{2} + 2pq + q^{2} = 1

2pq represents the frequency of heterozygote individuals, so:

genotype A1A2 = 2*0.8*0.2 = 0.32.

Thus, the frequency of brown beetles (A1A2) in the population is 0.32.

The inability of organisms to evolve anything that could be an advantage reflects _____.
sergey [27]

The inability of organisms to evolve anything that could be an advantage reflects "the limit of historical constraints".

<h3>What is the limit of historical constraints of evolution?</h3>

Although evolution is a powerful process that leads to

rapid changes in the characteristics of organisms, limits

to evolution arise from a lack of genetic variation, a

loss of well-adapted genotypes in populations due to

gene flow, trait interactions leading to trade-offs, and/

or the difficulty of evolving simultaneous changes in a

number of traits. This is the limit of historical constraints of evolution.

<h3>What are the factors that can cause an organism to evolve?</h3>

Four main factors lead to evolution:

(1) the potential for a species to diversify;

(2) heritable genetic variation among individuals within a species as a result of mutation and sexual reproduction;

(3) competition for scarce resources; and

(4) the spread of organisms that are better able to endure and procreate in the environment.

How does variation of beak type affect a birds ability to survive?
Blababa [14]
The variation in beak type enables the different individuals in a population to feed on different food sources.

The shape of the beak is key to determining the primary food source of the bird. Certain birds species have specialized beaks, but within populations of those species, there is a variation in beak shape.
This gives the population the ability to respond to changes in the environment and availability of different food sources.
For example, if because of a dry period there is a shortage of fruit, some individuals in the population have the beaks that enable them to feed on other things, survive and leave offspring.
