Light and dark moth natural selection experiment

Biology
1 answer:
S_A_V [24]3 years ago
3 0

Answer:

The evolution of the peppered moth is an evolutionary instance of directional colour change in the moth population as a consequence of air pollution during the Industrial Revolution. The frequency of dark-coloured moths increased at that time, an example of industrial melanism. Later, when pollution was reduced, the light-coloured form again predominated. Industrial melanism in the peppered moth was an early test of Charles Darwin's natural selection in action, and remains as a classic example in the teaching of evolution.[1][2] In 1978 Sewall Wright described it as "the clearest case in which a conspicuous evolutionary process has actually been observed."[3][4]

The dark-coloured or melanic form of the peppered moth (var. carbonaria) was not known before 1811. After field collection in 1848 from Manchester, an industrial city in England, the frequency of the variety was found to have increased drastically. By the end of the 19th century it almost completely outnumbered the original light-coloured type (var. typica), with a record of 98% in 1895.[5] The evolutionary importance of the moth was only speculated upon during Darwin's lifetime. It was 14 years after Darwin's death, in 1896, that J.W. Tutt presented it as a case of natural selection.[6] Due to this, the idea widely spread, and more people believed in Darwin's theory.

Which of these ideas correctly states a relationship between the practice of conserving energy and the effect that it has on peo
Bess [88]

The idea that correctly states a relationship between the practice of conserving energy and the effect that it has on people's health is: Energy conservation promotes less air conditioner use and warmer homes (option B).

<h3>How is energy conserved?</h3>

To conserve means to use judiciously or wisely, therefore, energy conservation refers to the effort made to reduce the consumption of energy by using less of an energy service.

The conservation of energy helps to reduce workload on mechanical devices such as air conditioner, cooker etc.

Therefore, the idea that correctly states a relationship between the practice of conserving energy and the effect that it has on people's health is: Energy conservation promotes less air conditioner use and warmer homes.

Please place the following vessels in the correct order to represent the arterial circulation leading up to the glomerulus.
Ymorist [56]

The following vessels are connected as below:

aorta ->renal arteries ->segmental arteries ->interlobular arteries ->arcuate arteries ->cortical radiata ->afferent arteries ->glomerulus.

1) aorta : arises from heart which carry blood from heart to the rest of the body

2) renal artery :it arises from the aorta which carry blood to kidney .it carry unfiltered blood .

3)segmental arteries : it arises from renal artery .it has  5 branches or segments.

4)interlobular arteries : it arises from segmental arteries. the interlobular arteries pass directly outward between the medullary rays to reach the fibrous tunic ,where they end in the capillary network of this part.

5)Arcuate arteries: it arises from interlobular arteries .it is also known as arciform arteries, are vessels of the renal circulation. they are located at the border of the renal cortex and renal medulla.

6) cortical radiata: it arises  from arcuate arteries.

7) afferent arteries: it arises from interlobular arteries and also connects to glomerulus. they are a group of blood vessels that supply the nephrons in many excretory systems .they play a important role in regulation of blood vessels.

8) glomerulus : it connects from afferent arteries.it is the filtering unit of kidney ,is a specialised bundle of capillaries that are uniquely situated between two resistance vessels.

Disclaimer: the given question is incomplete means it contains incomplete data .the correct question is given below.

Question: Please Place The Following Vessels In The Correct Order To Represent The Arterial Circulation Leading Up To The Glomerulus. Aorta Interlobar Artery Segmental Artery Afferent Arteriole Cortical Radiate Renal Artery Arcuate Artery Glomerulus

Please place the following vessels in the correct order to represent the arterial circulation leading up to the glomerulus.

Aorta

Interlobar artery

Segmental artery

Afferent arteriole

Cortical radiate
