Hello :)

Monoculture is the agricultural practice of producing a single crop, plant, or livestock species, variety, or breed in a field or farming system at a time.

Hope this helps some, good luck!! ;)

Blood flow is regulated in all three types of blood vessels through ____________ and dilation.

IrinaK [193]

*Blood flow is regulated in all three types of blood vessels through constriction and dilation.

*Contraction of blood vessels slows blood flow, while relaxation of blood vessels, or dilation, allows free flow of blood.

*Muscle fibers control the constriction and dilation of vessels. In the capillaries, rings of muscle called capillary sphincters control blood flow.

*The directional flow of blood in the veins is controlled with valves , which prevent backward blood flow when closed, and allow blood to flow only toward the heart when open.

Vasoconstriction and vasodilatation allow blood vessels (arteries and veins) to control blood flow and thus control the blood pressure. This is possible because of the smooth muscle cells that surround the vessels. The contraction and dilatation of those muscles is controlled by chemical signals (e.g. norepinephrine constricts the vessels, while NO dilates them).

Dominik [7]

Answer:

As sediment increases, reproductive success in corals declines.

Explanation:

As species are shifting, biodiversity is declining and ecosystems are losing,
Marine heatwaves are causing coral reefs to bleach and mass die-offs of fish and other wildlife,
Swamps can retain sediments and can grow vertically at rates equal to where trees are grown around crops to increase biodiversity.

Two species of tree frogs that live sympatrically in the northeastern United States differ in ploidy: Hyla chrysoscelis is diplo

Artist 52 [7]

Answer:

The correct answer is - polyploidy.

Explanation:

Speciation can be two types allopatric and sympatric speciation. Sympatric speciation is the process of speciation is developing the new species that diverged from the common ancestral species while the ancestral and developed species both can share the same place or geological area. The main cause of such speciation is due to the change in their genetic level more than environmental conditions.

In this case, the frog's species show differences in their ploidy level as well as their mating call but polyploidy is the most likely the difference that evolved first rather than females call for mating.

Thus, the correct answer is - polyploidy.
