Why does the moon turn red during a total lunar eclipse?
vagabundo [1.1K]

Answer:

In the case of a lunar eclipse, red light can pass through the Earth's atmosphere and is refracted - or bent - toward the Moon, while blue light is filtered out. This leaves the moon with a pale reddish hue during an eclipse.

Nonamiya [84]

The provided question is incomplete as it lacks the image required to identify the, however the correct image is attached:

Answer:

B is protein

C is the process of translation

Explanation:

The given image is a flow chart representation of the process of the protein synthesis from the DNA molecule by a two-step process that is combinedly known as the central dogma.

The first step is a transcription in which an RNA molecule (mRNA) is synthesized from the DNA molecule in organism nucleus (in eukaryotes only). The second step is to making a polypeptide chain of amino acid with help of rRNA, tRNA, and mRNA, this process is known as translation and represented in the image as C and B is the protein that formed.

Thus, the correct answer is - B is protein

C is the process of translation

write the order that blood moves through the heart beginning with the return of blood to the heart from the upper and lower port
statuscvo [17]

Answer: circulatory system

Explanation:

Blood that return from the upper and lower parts of the body are deoxygenated hence they are transported to the heart for oxygenation. therefore blood enter the heart through vena cava ( the main vein) to the right auricles and it goes to the lower part of the heart which is the right ventricles which is more muscular. due to this blood is pumped from the right ventricles through pulmonary vein which pumps blood to the left ventricles through pulmonary artery and it is allowed to the left ventricles in the lower part of the heart and it pumped back in the body through the aorta( the main artery) .

Two scientists in British Columbia are counting trout spawning grounds (called redds) along 5 km of a stream. The presence of
Eva8 [605]

The most likely reason for the scientists to count different numbers of redd is the observer’s efficiency.

Explanation:

In a field survey based on visual counting for visual stock assessment, the scientists may count a different number of redds each time in the same area due to the observer’s or the scientist’s efficiency.

The same place may first appear as redd and then later may not and accordingly the scientist's count also varies.

This error happens due observer’s inexperience in surveying, misidentification of redd species, changes or variations each time in the redd habitat, survey life, characteristics, spawning shifts etc., and poor temporal and spatial coverage.
