Answer:

Homologous structure

Explanation:

Homologous structures refers to organs or bones that have similar anatomical features found in different animals that are suggested to have the same common ancestor and serves as an evidence of evolution.

Whakes, humans and cats have similar bones in the same order but different in function.

Answer and Explanation:

The fact that whales, humans, and cats all have the same bones in the same order, but they matured differently in later embryological development, is an example of homologous characters or homologous structures.

Homologous characters have the same fundamental structures. They also share the same relations with adjacent structures, and they have the same embryological development.

These structures might show variations between organisms exhibiting them, according to their function and to the environment in which the organism lives.  

These homologous characters are common in organisms related and that share a common ancestor.

Answer:

The fossil of the dinosaur looked like it was a combination of two different types of extinct organisms: the meat-eating Tyrannosaurus rex and the Brontosaurus, which was an herbivore. Frankenstein was the name of a monster in a popular story about a scientist who built a monster in a lab. However, this species of dinosaurs evolved naturally. So, calling this species “Frankenstein” wouldn’t be completely accurate.

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.

California is home to the largest, tallest, and oldest trees on earth, all of which are
zhuklara [117]
California is home to the largest, tallest, and oldest trees on earth, all of which are gymnosperms.
Gymnosperms are plants that have seeds and are usually coniferous trees. Given that those largest, tallest, and oldest trees are sequoias, this seems to be the correct answer.
Nonvascular plants are quite small. Seedless vascular plants is also incorrect, because sequoias have seeds. Angiosperms are flowers.
