Rainbows, like the one shown below, form when sunlight passes through raindrops and is separated into different colors.
What happens to the sunlight when it passes through the raindrops that causes the rainbow to form?
A.
The sunlight travels in a straight line through the raindrops.
B. The sunlight is absorbed by the raindrops.
OC.
The sunlight is reflected off of the raindrops.
D.
The sunlight is bent and redirected by the raindrops.

Answer:

D. The sunlight is bent and redirected by the raindrops

Explanation:

This is refraction of light.Understand clearly the difference between reflection which is the bouncing back of light on shiny smooth surfaces and refraction is the bending of light therefore when the sun rays hit the raindrops it is bent and the light is split from a white colour to seven colours known as spectrum

How can I get my own karyotype?

If you guys don't know what karyotype is, it's a photo of person's full set of chromosomes. So basically my crush keeps making fun of me and said "You're so d*mb, you probably lost a chromosome" but I didn't lose any. So I want to sign up to get my own karyotype to prove I have a full set of chromosomes. Do you guys know which site I can sign up and pay to get my karyotype done? Thx

what is liver in mammalian body​

Phage are viruses that must infect bacteria to reproduce. Viral genomes do not contain all the genes needed to produce all proteins necessary for DNA replication, RNA transcription, and protein translation; instead the viruses force bacterial proteins and enzymes to express phage genes instead of bacterial genes.
Phage are very adaptable, and their behavior depends on whether conditions are favorable or unfavorable for making more phage.
When bacteria are plentiful (favorable conditions), viral DNA within the bacteria remains separate from the bacterial chromosome, and the virus forces the bacteria to make more virus. When the amount of virus becomes too much for the cell to hold, the membrane ruptures, and viruses are released to infect surrounding bacteria. This is known as the lytic cycle.
When bacteria are scarce (unfavorable conditions), the viral DNA within the bacteria becomes integrated into the bacterial chromosome. The bacteria survive and are still able to reproduce; viral DNA is transmitted to daughter cells when the bacteria reproduces. This is known as the lysogenic cycle.
As you just read, phage depend on bacteria to reproduce. Phage can be maintained by infecting a culture of bacteria with a strain of phage, and then plating the bacteria on an agar plate to grow.
Suppose that you isolate two mutant strains of phage - one strain cannot enter the lytic cycle and the other strain cannot enter the lysogenic cycle. You also grow wild-type phage as a control. You see three different phenotypes:
A plate with no missing bacteria- the lawn of bacteria is intact
A plate with spots/circles (called plaques) where there are absolutely no bacteria in the circles
A plate with spots/circles (called plaques) where there are some bacteria in the center of the circles.
Based on what you know about what happens in each cycle, match the plating results with the identity of the strain.
Drag each plate into the correct category.

Heparin, a highly negatively charged glycosaminoglycan, is used clinically as an anticoagulant. It acts by binding several plasma proteins, including antithrombin III, an inhibitor of blood clotting. The 1:1 binding of heparin to antithrombin III seems to cause a conformational change in the protein that greatly increases its ability to inhibit clotting. What amino acid residues of antithrombin III are likely to interact with heparin

Sinkholes are extremely dangerous because they occur quickly and without warning. Sinkholes are a result of both mechanical and chemical
weathering.
