As part of a forensic analysis, you have been asked to determine an individual's ancestry using skeletal indicators. The metric measurements you collect indicate that the individual is of European ancestry, but you see several nonmetric traits in the cranium that are typically found in individuals of Asian ancestry. Why might the two methods give different results
Answer:
Due to difference in the methods that is used for analysis.
Explanation:
The two methods give different results because we used two different types of measurements i. e. metric measurement and nonmetric traits. In the metric measurement, we calculate the quantitative character of an individual that gives information about the current status of an individual, while on the other hand, in non-metric traits refers to the method which is used to evaluate genetic connections within and between populations that were present in the past.

Rosa eats a peanut butter sandwich for lunch. Peanut butter contains a lot of protein, and bread is mostly starch. Rosa plans to go for a run later this afternoon. Rosa is breathing normally.
What does she need from the food she ate and the air she breathes so that she can go on her run? How do Rosa’s body systems work together to get the molecules she needs into her cells? How do her cells use these molecules to release energy for her body to run?

3. There are multiple types of mutations in DNA.
mutations occur when a single base is
changed to a different base pair.
mutations remove one or more bases from a segment of DNA,
resulting in a frameshift mutation.
mutations are also considered frameshift mutations, and occur when
one or more extra bases are added to a segment of DNA.
Check Answer
Answer:
substitution, deletion, insertion (in that order)
Explanation:
I did the assignment-
Mutations occur when a single base is changed to a different base pair; mutations remove one or more bases from a segment of DNA, resulting in a frameshift mutation, so this is also correct in other statements.
What is the significance of the DNA mutation?Mutations in DNA lie in their ability to alter the genetic information, and that altered information is passed on to next generations while Some mutations have no effect on the function of the proteins, but some have serious effects. It helps in the evolution process by providing a mechanism for the development of new traits, etc., in nature, so it has a significant role in it.
Hence, mutations occur when a single base is changed to a different base pair; mutations remove one or more bases from a segment of DNA, resulting in a frameshift mutation, so this is also correct in other statements.

Adult sponges a. have body walls with many pores. c. are active swimmers. b. possess true tissues. d. use stinging cells to capture prey.
Answer:
A
Explanation:
Chromosomal mutations are changes in the normal structure or number of chromosomes. Changes in chromosome structure can result from errors in meiosis or from exposure to radiation or other damaging agents. Certain changes in chromosome number can result from nondisjunction during either meiosis or mitosis. Both structural mutations and nondisjunction can play a role in trisomy 21, commonly known as Down syndrome.
Answer:
Yes.
Explanation:
Yes, both structural mutations and nondisjunction can play an important role in trisomy 21 which also called down syndrome. In this type of syndrome, extra copy of chromosomes is present in the cell. Down syndrome is a genetic disorder that causes various defects in the children such as learning problems, facial features, vision and hearing problems.

20. Allosteric effectors: a. can cause large changes in enzymatic activity. b. can lead to a decrease in the availability of a protein. c. do not alter the sensitivity of a metabolic pathway. d. decrease the sensitivity of the enzyme at nearly all concentrations of substrate. e. alter enzyme activity by binding to the active site of an enzyme.
Answer:
a. can cause large changes in enzymatic activity.
Explanation:
An enzyme refers to a biological catalyst that is typically used to speed up (accelerate) the rate of a chemical reaction by lowering the activation energy of its reactants.
When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy. Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
An allosteric effector can be defined as an agent, organ or molecule that is being binded to an enzyme at a site, thereby causing a reduction (negative effect) or an increase (positive effect) in an enzyme activity.
Hence, an allosteric effector can cause large changes in enzymatic activity because it acts as an intermediary and mediates specific effect in a metabolic pathway.

Using the concepts of chain of custody it is important to (multiple answer) A. document everyone who has handled the evidence prior to a trial B. record the dates and times of the possession of the evidence C. have a complete inventory of the evidence D. weight all of the evidence E. seal all of the evidence in air tight bags
Answer:
A. document everyone who has handled the evidence prior to a trial
Explanation:
A chain of custody can be defined as a paper trail containing the chronological order of items of evidence and how they have been handled, controlled, transferred, analyzed, and disposed during the investigation of a case.
This ultimately implies that, a chain of custody contains all the details or informations regarding the investigators (people) who handled, controlled, transferred, analyzed, and disposed an evidence in the course of carrying out investigations on a particular case. The most important and significant part of an investigation is the evidence because it helps to unravel the truth and facts relating to a case. Therefore, it is very important and essential to document and maintain a chain of custody so as to preserve the evidence.
Hence, using the concepts of chain of custody it is important to document everyone who has handled the evidence prior to a trial.
