The bones are: malleus (hammer-shaped) , incus (anvil-shaped) and stapes (stirrup-shaped).

They are together known as ear ossicles.

They transmit the vibrations from the eardrum or tympanum to the inner ear.

It has been stated that “species form a boundary for gene flow”. What does this mean? Are there exceptions to this statement? Ex
maks197457 [2]

Answer:

It means that species are selective when they are on copulation, and try to mix their genes with other individuals of its own population.

Yes, there are some exceptions like when there is not a lot of population and the individuals have to copulate with very close gene individuals to keep the species alive.

Explanation:

Gene flow has 2 important complex states and are: inbreeding and exogamy.

in Inbreeding, very close individuals from an species (Brother and sister, mother and son, father and daughter etc.) coopulate and generate new individuals, this copulation is something that doesn't help the species because stimulates recessive genes, and makes the population more susceptible to diseases.

In exogamy it's the contrary, mix genes from two individuals who are really different genitecally causes that the individuals have no common characteristics and they are more susceptible to the environment.

Which situation describes parasitism?
skad [1K]

Answer:

D. Ticks live on and drink blood from a cow.

This is an example of parasitism, where the ticks (parasite) are living off of the blood of the cow, the host animal.

Explanation:

Parasitism is a relationship between organisms. In this relationship, one organism (parasite) lives on or in another organism (host) and gains benefits from the host, causing it some harm.

Parasites are classified as ectoparasites, which live on the body surface of the host (ticks, fleas, leeches, and lice) and endoparasites, which live in the body of the host. Endoparasites are either intercellular, which live inside the host’s body (round worms, tapeworms) or intracellular, which live inside the cells in the host’s body (bacteria or viruses).

Parasites help to control dominant species and has a role in evolution by transferring genetic material between species.

Aleks [24]

Answer:

Edema occurs when blood pressure exceeds the counteracting force of the vascullar walls in the bloodstream, so fluid remains in the spaces surrounding cells and body tissue swells.

Explanation:

The intravascular hydrostatic pressure increases due to an increase in fluids, therefore the vessel walls begin to perceive this increase in pressure in their walls, generating fluid extravasion to areas of lower pressure.
