Why do scientist use different units than the si base unit?

1 answer:

6 0

Scientists use different units than the si base unit for communication among scientists all over the world to be efficient and perpsicuous. In other words, scientific data and thoughts can easily be communicated through the same units other than the si unit.

Hope this helps.

Describe how oxygen and carbon dioxide diffuse both between the 1) alveoli and the blood, and 2) blood and the body tissues. Inc

sukhopar [10]

The change in partial pressure from the alveoli (high concentration) to the capillaries (low concentration) drives the oxygen into the tissue and the carbon dioxide into the blood (high concentration) from the tissues (low concentration), which is then returned to the lungs and exhaled.
Once in the blood of the capillaries, the O2 binds to the hemoglobin in red blood cells which carry it to the tissues where it dissociates to enter the cells of the tissues.
The lungs never fully deflate, so air that is inhaled mixes with the residual air left from the previous respiration, resulting in a lower partial pressure of oxygen within the alveoli.

The correct answer is : Non-native species is the example that affects biodiversity.

These species can be an agent of unacceptable economic, biological or social aftermath.

However, these species still provides in the regional biodiversity like biotic interactions and species richness and ecosystem services.

What are the genotypic and phenotypic distributions for the F1 and F2 generations from a cross between a chick with black (BB) f

lord [1]

Answer:

Please find the punnet square to this question as an attachment

F1 generation:

genotype = BW

Phenotype = Erminette offsprings

F2 generation:

genotype = BB (1): BW(2): WW(1)

Phenotype = 1 Black, 2 Erminette, 1White

Explanation:

This question involves a gene coding for feather color in chickens. The allele for black feathers (B) is codominant with the allele for white feathers (W) to form an erminette chicken (black and white speckles).

According to this question, a cross between a chick with black (BB) feathers and chicken with white (WW) feathers will result in an all erminette chicken (BW) in the F1 generation (see attached image)

Also, in the F2 generation got by self-crossing the Erminette genotype in the F1 generation (BW), the following genotypic and phenotypic ratios are observed:

Genotypic ratio = BB (1): BW(2): WW(1)

Phenotypic ratio = 1 Black, 2 Erminette, 1White
