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.

What is cyclin dependent kinase?​
Bezzdna [24]

Answer:

please mark as brainliest answer as it will also give you 3 points

Explanation:

Cyclin-dependent kinases (CDKs) are the families of protein kinases first discovered for their role in regulating the cell cycle. They are also involved in regulating transcription, mRNA processing, and the differentiation of nerve cells.[1] They are present in all known eukaryotes, and their regulatory function in the cell cycle has been evolutionarily conserved. In fact, yeast cells can proliferate normally when their CDK gene has been replaced with the homologous human gene.[1][2] CDKs are relatively small proteins, with molecular weights ranging from 34 to 40 kDa, and contain little more than the kinase domain.[1] By definition, a CDK binds a regulatory protein called a cyclin. Without cyclin, CDK has little kinase activity; only the cyclin-CDK complex is an active kinase but its activity can be typically further modulated by phosphorylation and other binding proteins, like p27. CDKs phosphorylate their substrates on serines and threonines, so they are serine-threonine kinases.[1] The consensus sequence for the phosphorylation site in the amino acid sequence of a CDK substrate is [S/T*]PX[K/R], where S/T* is the phosphorylated serine or threonine, P is proline, X is any amino acid, K is lysine, and R is arginine.[1]

Can you recognize the eight stages of meiosis based on the location and behavior of the chromosomes? drag the diagrams of the st
Paul [167]
In meiosis, cell division will occur two times. It shall be called Meiosis I and Meiosis II. And Meiosis happens to our sex cells, egg for female and sperm cells for the male. There four stages in Meiosis I, Prophase I will happen when who homologous chromosomes exchange DNA. Metaphase I will happen when the pair move together in the center. Anaphase I is when the who homologous chromosomes are pulled apart to opposite poles. Telophase I is when the the first division of the chromosomes happen. Producing two 24 chromosomes cells. The nest division will produce haploid or 12 chromosome cells. In Propase II, the nuclear walls will disappear once again, in the Metaphase II the cells will meet again in the center. In Anaphase II the chromatids will be pulled apart. And then lastly in the Telophase II, the chromatids will not be 2 haploids. So in Meiosis, 4 sex cells are produced.

Which of the following is an example of genetic discrimination?
Rudiy27

Timothy does not get a promotion at work because he has cancer is an example of genetic discrimination.

Explanation:

Genetic discrimination is termed so when an employer or an insurance company treats indifferently an individual with gene mutation or heritable diseases.

The act of not giving promotion and using the genetic information for the reason by the employer is indifferent and termed genetic discrimination as in case of cancer where life expectancy and large insurance claim is the reason.

Insurance companies do not give benefits or insurance to potential people having or prone for having the mutation and heredity disease.

To help overcome this discrimination federal level laws have been implemented as Genetic information non discrimination act. It strictly prohibits the indifferent behaviour of the employers and insurance companies.
