blood flows more slowly in the capillaries than in the aorta. why?

Answers

Answer 1

Answer:

because it a smaller part

Explanation:

Answer 2

Due to the capillaries' large overall cross-sectional area, blood flow there is slow, allowing for adequate nutrition exchange.

How blood flows through blood vessels?

The rate of blood flow dramatically decreases as it enters arteries, arterioles, and eventually, capillary beds, slowing to roughly 0.026 cm/sec, or 1,000 times slower than the aorta.

The capillaries, where blood flow is the slowest, provide time for the exchange of gases and nutrients. A force that opposes a fluid's flow is called resistance.

The majority of blood vessel resistance is caused by the size of the vessel. Blood flow reduces as vessel diameter shrinks due to an increase in resistance.

Therefore, the high total cross-sectional area capillaries blood flows more slowly.

•Flood plain

Answers

Deposition by rivers generates alluvial fans and deltas. Moreover, erosion by rivers generates waterfalls, flood plains, oxbow lakes and meanders.

An oxbow lake is a lake located in a meandering channel, and therefore on a floodplain.

Alluvial fans are accumulations of sediments created as flowing water bodies interact with mountains or hills.

A delta is a formation of land composed of sediments located in the mouth of the river.

A waterfall is a point in a river where water spills suddenly downward.

A growing community considers building a new hospital closer to residential neighborhoods. This will get residents to emergency care faster and save lives when it is
needed. The only land available near residential areas is a forested wetland that supports a variety of species. What is a social consequence of not using the land
for a new hospital?
Emergency care is farther away, risking the health and well-being of a growing community
Preserving the ecosystem may upset residents in a community with a hospital shortage.
O If the wetland is protected, residents have fewer environmental concerns about the area.
It protects the lives of species and prevents a reduction in carbon sequestering by the trees.

Answers

The social consequence of not using the land is that it will protect the lives of species and prevents a reduction in carbon sequestering by the trees.

A social consequence refers to any unforeseen event which can be positive or negative, experienced by a society and has an effect on them.

A positive social consequence benefits a group of the socially connected group and can also stimulate future purpose.

A negative social consequence has its repercussions and can be attributed to negligence and bad factors.

Conservation of the ecosystem is paramount as well as the survival of the community.

A positive social consequence from the given information is that if the forested wetland is preserved to support a variety of species, It will protect the lives of the species and prevent a reduction in carbon sequestering by the trees.

The community could have emergency ambulances to cater for the movement of patients in case of emergency to the hospitals or educate them on how to take good care of their health and how to minimize hazards at home and offices.

Answers

Answer: Hey! its a fellow classmate from K-12! Alright so what I put for the lab report question is :  The properties used to identify the metals were mass, length, and volume. These were the extensive properties that I used. I would propose to test color, malleability, melting points, and to test how shiny or dull it is. I would propose these to increase the certainty in the identity of the metals.  Btw, please mark me brainliest.

Explanation: When it says evaluate It pretty much means " tell me what you used to figure out the identity of the unknown metals".

The part where it says " propose, revise...blah...blah blah means " How could you increase your chance to get the right metal identity, henceforth saying what properties and tools could we use to make this experiment more better; better chances of getting the right identity of metal.

Neural impulses are transmitted to bipolar cells when light energy enters the eye and triggers ________ in the rods and cones.

Answers

Neural impulses are transmitted to bipolar cells when light energy enters the eye and triggers CHEMICAL CHANGES in the rods and cones. This process is known as phototransduction.

Phototransduction refers to the process by which photoreceptors convert light into electrical signals.

Photoreceptors (i.e., rod and cone cells) are specialized cells in the retina of the eye which are capable of converting light into electrical signals and thus trigger different physiological processes.

Phototransduction is triggered by the activation of signaling proteins, that open or close ion membrane channels in photoreceptor cells.

in cells regulation allows rapid response to changes in the environment; in cells, gene regulation is critical for maintaining homeostasis.

Answers

Given what we know about biological mechanisms, we can confirm that both of these statements are in fact true in regards to regulation and gene expression.

Homeostasis is the body's ability to maintain constant a series of processes and values that we need in order to survive. To do this, regulation in cells is essential. Regulation allows us to respond rapidly to changes in the environment by regulating the processes which control the homeostasis for that environmental change.

Gene regulation or expression is another way in which the body maintains homeostasis. For example, in the presence of too much substrate, the gene encoding a specific enzyme might activate, causing the creation of the enzyme and getting substrate levels back to normal.

Inversely, if the body detects that substrate levels may be too low, the expression of any gene that may consume that substrate can be silenced, therefore maintaining a balanced level.

What are some geological characteristics of glaciers in Glacier National Park?

Answers

Answer:

The minimum size criterion for a glacier is 0 .1 km², or about 25 acres. Below this size, the accumulated ice generally does not move and is stagnant. Many years of snow accumulation compacts the bottom layers of snow into ice. Under the huge weight of the snowpack (usually 100ft/30.5m thick or more), the ice becomes viscous and allows the mass to slide downhill. The appearance of crevasses and cracks attest to a glacier’s movement. Glaciers don't "bulldoze" landscape as much as they melt and re-freeze, plucking material from areas of snow deposition and moving it to other areas, like downhill conveyor belts.
