Answer:
a. The substance is from an animal source.
Explanation:
Glycogen is a carbohydrate polymer in which animals store their excess glucose as. When animals digest their ingested food, it gets broken down into GLUCOSE. This glucose, when in excess, gets stored as GLYCOGEN.
According to this question, a substance found at a crime scene is being examined using chemical tests. The test revealed that glycogen is present in the substance. This can mean that the substance is from an ANIMAL source because GLYCOGEN is only present in animals.
Answer:
a. The substance is from an animal source.
Explanation:
I, myself, took the exam, but also glycogen is found in animals cells. It is a branch of glucose that is usually stored in liver and the skeletal muscle.
Which of the following are pyrimidine?
A. Guanine and cytosine
B. Thymine and Guanine
C. Cytosine and uracil
D. Guanine and adenine
E. Adenine and thymine
Answer:
c.Cytosine and uracil
Explanation:
Two types of Nitrogenous bases(heterocyclic aromatic molecules) are found in DNA and RNA: 1.Pyrimidines and 2.Purines
Pyrimidines:Thymine(5-methyl-2,4-dioxypyrimidine) and Cytosine(2-oxy-4-aminopyrimidine) are found in DNA . Uracil (2,4-dioxypyrimidine) and Cytosine (2-oxy-4-aminopyrimidine) are found in RNA.
Purines:Adenine (6-aminopurine) and Guanine(6-oxy-2-aminopurine) are the two purine bases that are found in both DNA and RNA.

(JUST GIVE ME THE 2 REASONS GOOD AND BAD NO NEED FOR A PARAGRAPH ILL DO IT) Since we can use DNA fingerprinting to catch criminas, why not have every American give a DNA sample so everyone is on file to make it easier to catch criminals . write 1 paragraph supporting this and 1 paragraph explaining why it would be a bad idea .
Answer:
(Bad idea)
Many people are against the idea of extending the DNA database because of the potential threat it has to our privacy. While a DNA profile provides very little information about someone, their DNA sample contains information that can reveal their ethnicity or how susceptible they are to disease. The risk of data abuse is therefore potentially high.
(Good idea)
A DNA database of everyone may make it easier for police to identify missing people and unidentified remains.
I found a good article that is helpful for your paragraph. It supports both sides. It wont let me link so just type in :
"Is it ethical to have a national DNA database?" and it should be the first article that pops up
Answer:
why we should
Every American should give their DNA sample so then its easier, takes less time and so police can move on to other more important cases. Taking samples of DNA from all Americans would dramatically improve law enforcement's efficiency. Thousands of people have been convicted because suspects can be searched out across space and time based on DNA evidence. Hundreds of innocent people have also been freed, often after years behind bars, sometimes just short of the death penalty.
Why we shouldnt
Taking every single american dna will take a long time and will take alot of money and resources. And sometimes your genetic information could be sold to the highest bidder. And sometimes The results are often inaccurate.
i couldnt find more reasons why we shouldnt so you should go over why we should section more

Which statement describes the wave interactions in sound navigation and ranging (SONAR)?
O A. Sound is transmitted through the water and diffracted by hard surfaces.
o
B. Sound is transmitted through the water and reflected by hard surfaces.
о
C. Sound is diffracted through the water and transmitted by hard surfaces.
о
D. Sound is diffracted through the water and reflected by hard surfaces.
Answer:
B
Explanation:
In sound navigation and ranging (SONAR) the sound wave is transmitted through water and it will reflect by hard surfaces, hence option b is correct.
What is sound navigation and ranging (SONAR)?Sonar is used to create nautical charts, find underwater navigation hazards, search for and map things on the seafloor such as shipwrecks, and map the seafloor itself, waves are transmitted into the water and reflected by hard surfaces.
The transmission and receiving of sound waves are involved in active sonar. For example, when a submarine is used to map the topography of the ocean floor.
it emits sound pulses, known as pings, towards the bottom of the ocean in its area Sound is transmitted through the water and hard surface reflection.
Therefore wave interaction in sonar is sound is transmitted in water and reflected by hard surface, hence option b is correct.

4. All the following impact water clarity except for
O A. light penetration
B. phytoplankton
C. suspended sediments
D. nutrients
Answer:
A. light penetration
Explanation:
Water clarity refers to how clear a water is, and it is a measure of how far/deep light can penetrate into such a water body. A water that is not clear is said to be TURBID. Several factors affect the clarity of a water body and they include;
- Phytoplankton, which refers to floating algae on the water body. An accumulated growth of phytoplankton can affect the penetration of light into the water, hence, making the water unclear.
- Suspended sediments can also block the penetration of light into the water, reducing water clarity.
- Nutrients in form of fertilizer or waste materials can also make water unclear.
Therefore, LIGHT PENETRATION DOES NOT IMPACT WATER CLARITY, rather it is dependent on water clarity.
Consider an organism that has a dominant phenotype, is it possible to determine its genotype? explain your answer
Answer:
Yes, it is possible via testcrossing
Explanation:
The law of dominance has made it possible that a phenotype may be expressed without knowing the actual genotype (allele combination). This occurs when an allele is dominant over another allele (recessive), hence, the dominant phenotype can either be in a heterozygous or purebred state.
However, a way to discover the genotype of an organism that is portraying dominant phenotype is TEST CROSS. Test cross is the crossing of the unknown genotype with a recessive condition (will contain same recessive alleles).
After crossing, the offsprings will be used to determine whether the parent with unknown genotype is heterozygous or not.
- If the offsprings all exhibit the dominant phenotype, the unknown genotype contains the same dominant alleles e.g DD.
- If 50% of the offsprings exhibit a recessive phenotype, the unknown genotype is heterozygous e.g Dd.

what conditions can cause a population to decrease?
Answer:
if the population is too high and food is scarce.
high population attract predators.
high competition for food.
mutations.
Answer:
A reduction over time in a region's population can be caused by sudden adverse events such as outbursts of infectious disease, famine, and war or by long-term trends, for example sub-replacement fertility, persistently low birth rates, high mortality rates, and continued emigration.
Which best explains why a decrease in the types of insects in an ecosystem reduces the sustainability of the
ecosystem?
O Organisms that depend on insects may not survive, eventually harming all the organisms that are interconnected.
O The biodiversity of the ecosystem cannot be protected by laws unless there are a certain number of insect
species.
O There will likely be fewer insects that harm plants, causing an increase in plant diversity.
O Having fewer insects allows other organisms to use the resources that the insects were using.

The mosquitos have different traits because they have different proteins for body size feature in their cells. Differences in the structure of protein molecules affect how they interact with other protein molecules. A gene version provides instructions for making a specific protein, so mosquitos with different combinations of gene versions will have different proteins in their cells that result in small, medium, or large body sizes. Each parent randomly passes on one of its two copies of a gene for a feature, which is why each mosquito offspring can have a different combination of gene versions even though they have the same parents.
Answer:
The mosquitos have distinctive characteristics since they have diverse proteins for body measure highlight in their cells. Contrasts within the structure of protein atoms influence how they associated with other protein atoms. A quality form gives enlightening for making a particular protein, so mosquitos with distinctive combinations of quality adaptations will have distinctive proteins in their cells that result in little, medium, or huge body sizes. Each parent haphazardly passes on one of its two duplicates of quality for a include, which is why each mosquito sibling can have a diverse combination of quality forms indeed in spite of the fact that they have the same guardians.
