Explain how a crime lab could use paper chromatography to determine if lipstick found at a crime scene matched the lipstick of a
FromTheMoon [43]

Explanation:

The lipstick from the crime would be crushed and dissolved in an appropriate liquid solvent. The lipstick would then be placed in one of the ink spots on the starting / base line of the paper. Another spot would be created for the lipstick with which it is being compared with.

The paper chromatogram would then be placed vertically on a solvent that acts as the mobile phase. After some time, when the solvent reaches the solvent front  of the paper chromatography, by capillary action, the chromatogram can be removed and left to dry.

Bands will have appeared on the chromatography paper formed from the different components of the lipstick. The bands of the lipstick from the crime scene and that with which it is being compared to are observed. If the bands are all aligned, horizontally, then this means it is a complete match. The lipstick must have been the same used at the crime scene.

  An organism takes care of its young and produces few offspring. What type of organism is this? 
erma4kov [3.2K]

Answer:

K-strategists

Explanation:

Reproductive pattern in organisms can be typically categorised into two:

1. K- Strategy

2. R- Strategy

K-strategists are organisms that lives in very stable environments and gives birth to fewer organisms. Most of these organisms reproduce close the carrying capacity of their habitat. They offer support and protection to their progeny to the points where they become indepedent. The mortality rate is very low in such organisms and so is the birth rate too.

R-strategists are organisms whose main aim is to populate and dominate an environment. They reproduce exponentially and offers no life support to their progeny in their early developmental stage. They often occupy unstable and highly unpredictable environments. Most R organisms have a very low and short life expectancy. Since they produce more offspring and they live under adverse environments, mortality rate is high.

Examples of K-strategists are elephants and man

Examples of R-stategists are grasses and microbes.
