If you look at site 23 of the chromosomes, you can see whether the person is male of female:
Male: XY
Female: XX
The correct answer is A.
Oswald Avery applied several biochemical techniques to large cultures of bacteria in order to extract and purify the "transforming principle". Their experiments showed that most probably the "transforming principle" was DNA. One of the observations leading to this conclusion was that enzymes that degrade proteins or RNA (such ribonucleases) had no effect on the "transforming principle". On the contrary, enzymes degrading the DNA destroyed the extract's transforming capacity.
Answer:
Classification of biological organisms from most general to most specific is -
Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species
Explanation:
A hierarchy system of taxa or ranks of living organisms up to species level is known as taxonomic classification. It includes a higher and most generalized rank domain consist of archaea, bacteria, and eukarya. Second most generalized ranks kingdom that consist of various kingdoms.
Less generalized ranks are in order of a decrease in general and an increase in specificity are phylum, class, order, and family and the most specific ranks are genus and species.
1-refraction
2-transmission
3-reflection
4-diffraction
<u>Explanation:</u>
Refraction is the bending of a wave when it enters a medium where its speed is different.Refraction is responsible for image formation by lenses and the eye.
Transmission of light is the moving of electromagnetic waves through a material. This transmission can be reduced, or stopped, when light is reflected off the surface or absorbed by the molecules in the material.
Reflection is when light bounces off an object.Light is reflected when there is a mismatch between materials through which the light is travelling.
Diffraction is the slight bending of light. The amount of bending depends on the relative size of the wavelength of light to the size of the opening.
