Homologous structures provide evidence for common ancestry, whileanalogous structures show that similar selective pressures can produce similaradaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used todetermine species' relatedness.

Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor. Other evidence for evolution is provided by analogous structures. These are structures that unrelated organisms share because they evolved to do the same job.

How do homologous and analogous structures show evidence for evolution?

Answer:

This is called CODOMINANCE

Explanation:

Codominance is an inheritance pattern that does not conform to Mendel's principle of inheritance i.e. non-mendelian inheritance. Codominance is the process whereby two alleles of a gene are both dominant for their respective traits and hence are simultaneously expressed when in a combined or heterozygous state.

An example is the ABO blood group system in humans. Alleles for A and B are codominant, meaning that, the two traits will be expressed when the two alleles are combined to form AB. Hence, according to this question, when traits are COMBINED together and each are expressed, it is called CODOMINANCE.

Answer:

Cytokinesis, or “cell motion,” is the second main stage of the mitotic phase during which cell division is completed via the physical separation of the cytoplasmic components into two daughter cells. Division is not complete until the cell components have been apportioned and completely separated into the two daughter cells. Although the stages of mitosis are similar for most eukaryotes, the process of cytokinesis is quite different for eukaryotes that have cell walls, such as plant cells.

Answer:

Natural selection

Explanation:

Answer:

The awnser is Natrual Selection :)

Explanation:

Hi here is your awnser: Natural selection is the process by which organisms with variations most suited to their local environment survive and leave more offspring. In natural selection, the environment—not a farmer or animal breeder—influences fitness. Well-adapted individuals survive and reproduce.

The "subduction zone" will not be a type of plate boundary.

A subduction zone occurs when two tectonic plates collide and one plate dives through into the mantle beneath another plate.

The boundary among two plates would be known as a tectonic plate boundary. The plate is moving slowly, continuously, and in a variety of directions.

Therefore, the "subduction zone" will not be a type of plate boundary.

Answer:

Clouds form nuclei of condensation, where partial pressures of water accumulate.

Explanation:

When the partial pressure of water increases, it condenses in large quantities and due to differential pressures with the pressures of the earth's surface, rains or sudden changes are triggered.

Answer:

Normal level of calcium in the blood.

Explanation:

The normal range of PTH levels means that there is normal amount of calcium is present in the blood. If the PTH level is too high it means that the levels of calcium in the blood is very low while on the other hand, if the levels of PTH is low it means that the level of calcium in the blood is too high so that's why normal range of PTH level means normal level of calcium in the blood.

All of the Earth's living organisms can be divided into distinct categories in a variety of ways, but the most popular manner is through the use of a hierarchical classification scheme called taxonomy.

In this hierarchy, organisms are grouped based on shared traits, with each level getting more specialized as you descend.

From the broadest to the narrowest, the main taxonomic levels are:

The domain level of classification divides organisms into different cell types, and it is the widest level of classification. Eukarya, Archaea, and Bacteria are the three domains.

Kingdom: This level of classification divides organisms into groups based on their overarching traits and cellular make-up. Animalia, Plantae, Fungi, Protista, Archaea, and Bacteria are the six kingdoms.

Phylum: This level of classification divides creatures into groups depending on the structure and organization of their bodies.

Class – Based on similar structural, physiological, and behavioral traits, organisms are grouped at the class level.

Order: Organisms are categorized at the order level according to shared traits within a class.

Family: Within an order, organisms are grouped at the family level based on shared traits.

Genus – Based on their evolutionary connections and similar traits, species are grouped at the genus level.

Species - The species level of classification is the most detailed and divides organisms into groups based on their propensity to interbreed and give birth to live offspring.

Based on their traits and evolutionary connections, all species of life on Earth can be divided up into separate groupings using this classification method.

Therefore, all of the Earth's living organisms can be divided into distinct categories in a variety of ways, but the most popular manner is through the use of a hierarchical classification scheme called taxonomy.

Answer:

The second trophic level consists of organisms that eat the producers. These are called primary consumers, or herbivores. Deer, turtles, and many types of birds are herbivores. Secondary consumers eat the herbivores. Tertiary consumers eat the secondary consumers.

Explanation

An animal that eats producers is called herbivore. Therefore, option (D) is correct.

Herbivores eat plant matter such leaves, stems, fruits, and seeds. These organisms get energy and nutrients from producers, the main source of organic matter in ecosystems.

Cows, rabbits, deer, and many insects are herbivores. Herbivores transform plant biomass energy into a form that higher trophic levels can consume, making them vital to ecosystem energy and nutrient cycles. Therefore, option (D) herbivore is the correct option.
