Populations of the grasshopper Vandiemenella viatica possess different chromosomal fusions and inversions. Grasshoppers that are

svetlana [45]

Answer:

The options

a. New combinations of genes yielding genotypes of greater fitness

b. Few heterozygotes because of underdominance

c. Frequency-dependent selection, leading to fluctuations in fitness

d. Heterozygotes with greater fitness, owing to overdominance

e. A random assortment of genotypes because of genetic drift

The CORRECT ANSWER IS b.

b. Few heterozygotes because of under dominance

Explanation:

In genetics, underdominance (at times called "negative overdominance") is the opposite of overdominance.

It is the selection against the heterozygote, that leads to disruptive selection and divergent genotypes. It occurs in cases of inferior and reduced fitness (As in our case study, it is the different chromosomal fusions and inversions)

of the heterozygotic genotype to the dominant or recessive homozygotic genotype. It is unstable as it causes fixation of either allele.

Another example is the African butterfly species Pseudacraea eurytus, which makes use of Batesian mimicry to avoid predation. This species carries two alleles that gives a coloration that is alike to a different local butterfly species that is harmful to its predator. The butterflies who are heterozygous for this trait are observed to be intermediate in coloration and thus encounter an higher risk of predation and a decrease in the total fitness.

Water leaves the internal cavity of a sponge through the

Trava [24]

If I'm not mistaken, it leaves through the osculum which is a cavity located on the upper part of a sponge.

Sponges feed through a process called filtration, which means that they filter the water in search of nutrients. And after they collect everything they need from the water, they need to let it out somehow; through the osculum.

Hope it helped,

Although they share many of the same methods, forensic anthropologists often analyze the skeletal remains of only a single indiv

-BARSIC- [3]

Answer:

True

Explanation:

True

Forensic Anthropologist determine whether the bones provide evidence of the cause of death, to identify any individualistic features in the skeleton, and to estimate the time since death. The human pelvis provides the most reliable means for determining the sex of skeletal remains.
While bioarchaeologists usually analyze skeletal samples of many individuals. Bioarchaeologists are archaeologists who specialize in the study of skeletal remains at archaeological sites. The physical and chemical inspection of bones have the capacity to reveal a wide range of information about past peoples and societies, such as: Health. Diet. Lifestyle.
