What can dried blood tell an expert?

Biology

Blood dries over time. How quickly this happens depends on the surface on which the blood landed, how much blood the spatter contains, and the heat and humidity at the crime scene, but as a rule the outer edges of the stain dry first. Consequently, after the interior portion flakes off or is smeared by an object, a dry blood spatter can skeletonize, that is, leave behind a ring similar in appearance (if not color) to a water ring on a coffee table. Patterns of drying help analysts determine how long an assault went on, detect whether it took place all at once or in stages, and nail down possible crime scene contamination. Clotting patterns in blood provide similar information and can help nail down the time factor if analysts arrive at the scene before blood can dry. Clotting begins within 3 to 15 minutes, but actual times vary by amount, surface type and environment. Mixed levels of clotting can indicate that multiple blows or gunshots occurred over time

Answer:

Making a dry blood test can diagnose hepatitis C

Dry blood samples can detect both antibodies and hepatitis virus RNA successfully. It involves obtaining a few drops of blood by fingerprinting, and letting them dry on a specially specific absorbent paper card.

If I breed a short for FF female with a short for Ff male then I will expect to see what type of offspring
Usimov [2.4K]
If being short is the dominant trait, then you should expect the offspring to also be short.

This is because the traits are spread out as four different possibilities. Either FF, FF, Ff, or Ff. If the dominant trait is being short, “F” then this would mask the recessive trait “f”.

How do the main sequence stages of these two sizes of stars differ?
xxTIMURxx [149]
Stellar evolution is the process by which a star undergoes a sequence of radical changes during its lifetime. Depending on the mass of the star, this lifetime ranges from only a few million years (for the most massive) to trillions of years (for the less massive), considerably more than the age of the universe. ^ 

Small, relatively cold, low mass red dwarfs burn hydrogen slowly and will burn for hundreds of billions of years 

Massive hot supergiants will live for just a few million years. 

A mid-sized star like the Sun will remain on the main sequence for about 10 billion years. Hope tis helps!!

I believe your Answer would be:

A: Sister Chromatids.

Explanation:

A sister chromatid refers to the identical copies (chromatids) formed by the DNA replication of a chromosome, with both copies joined together by a common centromere. In other words, a sister chromatid may also be said to be 'one-half' of the duplicated chromosome.
