In 1918, the tsar (king) and tsarina (queen) of Russia and their five children were presumably assassinated and buried in an unmarked grave. Later, several women came forward and claimed that they were in fact Anastasia, one of the daughters whose bones had not been found. More recently, forensic scientists have extracted DNA, including mtDNA, from the skeletal remains of the tsar (father), tsarina (mother), and children. Which of the following samples of mtDNA would NOT be helpful in confirming that a woman is Anastasia?
a. the tsar and tsarina and living relatives of each of them.
b. each of the claimants or their living children.
c. the tsar, tsarina, and the other assassinated children.
d. the tsar and tsarina only.
e. the tsarina and the claimants.
The correct answer is B. Each of the claimants or their living children.
Explanation:
One of the basic principles in genetics establishes genes are passed from the parents to their offspring. Indeed, children receive 50% of genes from each parent. This implies the daughter of the tsar and tsarina will have share part of the DNA including mtDNA (mitochondrial DNA) of her mother, father, and siblings.
According to this, to prove if someone is Anastasia or not, it is possible to use the mtDNA sample from the tsar, tsarina, or death children but not from the claimants. This is because the claimants are not confirmed relatives of the tsar or the tsarina, and therefore their DNA cannot be used to determine if a woman is the daughter of the tsar and tsarina. Indeed, a woman claiming to be Anastasia can share DNA with another claimant and this does not prove they are related to the tsar and tsarina or that the woman is the real Anastasia.

how does pinocytosis work
Answer:
In cellular biology, pinocytosis is a type of endocytosis that involves the taking in of extracellular fluid into the cell. By utilizing this process, the cell can draw fluids and even solutes (as long as they are dissolved in fluids) into the cell with only a small amount of energy (ATP) needed.

The ability to carry out photosynthesis (using the energy in sunlight to make sugar)...
A. would be a good item to add to the list of characteristics of life since there aren't any
non-living things that can do photosynthesis.
B. would be a good item to add to the list of characteristics of life because all life either
directly or indirectly gets its energy from the sun.
C. would not be a good item to add to the list of characteristics of life because not all
living organisms can conduct photosynthesis.
D. would not be a good item to add to the list of characteristics of life because someday in
the future, a non-living thing may be able to conduct photsynthesis.
E. Is currently one of the characteristics of life
Answer:
Is currently one of the characteristics of life
Explanation:
One major characteristic of life is nutrition. Nutrition refers to the process by which a living organism obtains its food.
Photosynthesis belongs to the kind of nutrition called autotrophic nutrition. Autotrophs are living organisms that produce their own food from simple inorganic chemicals.
Hence, only living organisms can undergo nutrition and it is already one of the characteristics of life.
How are proteins and carbohydrates similar?
Answer:
Proteins consist of units called amino acids, strung together in complex formations. Because proteins are complex molecules, the body takes longer to break them down. As a result, they are a much slower and longer-lasting source of energy than carbohydrates. There are 20 amino acids.

Consider a population of Clostridium difficile living in the human gut. Regular ingestion of an antibiotic is a selective process on the gut ecosystem. Which of the following events could be considered adaptive mutations for C. difficile in this environment? A. Acquisition of a plasmid with a gene encoding an enzyme to inactivate the antibiotic B. Deletion of the gene encoding a restriction endonuclease C. Duplication of the gene encoding flagellin D. Point mutation changing a single amino acid in a membrane transporter
Answer:Acquisition of a plasmid with a gene encoding an enzyme to inactivate the antibiotic
Explanation:
Clostridium difficile is a Gram-positive gastroimtestinal bacteria that forms spore it cause a range of diseases like antibiotic-associated diarrhea (AAD).
C. difficile genome harbors a variety of resistance genes that makes it resistance to different classes of antibiotics. Analysis conducted on C. difficile 630 genome identified genes encoding β-lactamase-like proteins and penicillin-binding proteins (PBPs) as one that mediate the resistance to the β-lactam antibiotics such as penicillin and cephalosporins this is done by an enzymes that unlocks the drug active site making the bacteria resistance to it.
A specific ligand is polar in nature. Where is the ligand-binding portion of the receptor most likely to be located?
Answer:
on the extracellular side of the cell membrane
Explanation:
Ligands can be defined as signaling molecules that interact with receptors localized on target cells. Protein ligands are generally polar and soluble in water. In consequence, they tend to bind with extracellular domain receptors localized on the cell surface, on the outside surface of the cell. Some examples of protein ligands include, among others, hormones (e.g., insulin), growth factors, neurotransmitters, etc.

What is the name of the solid part of Earth, including rock, minerals, and metals?
Answer:
Lithosphere is the name of the solid part of Earth, including rock, minerals, and metals.
Answer:
Geosphere/Lithosphere
Explanation:
The answer would be lithosphere but for this question it wouldn't' be because I took the test.So another word for lithosphere would be geosphere.These answers are both correct just that sometimes the test would only show one of these.

Answer:
uhm this is true is that is what your asking?
Explanation:
Lipids such as fats serve as a stored form of energy and are required for various functions of the body. The body needs to digest and absorb the fats we consume so that it can accomplish these functions.
Explain how available energy changes at each trophic level. What happens to the energy that is lost?
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. Trophic level transfer efficiency (TLTE) measures the amount of energy that is transferred between trophic levels

While monosaccharides typically all have a molecular formula that is a multiple of CH20, they differ in factors such as the length of the carbon skeleton or the orientation of their atoms around asymmetric carbon atoms. What is the impact of this variation in molecular structure? 1.) Different monosaccharides will form disaccharides with the same properties. 2.) Cells will use more energy to metabolize a wider variety of polysaccharides. 3.) Molecules that all share the same bonding pattern but have different properties will be produced. 4.) Sugars with different properties that can build a wide variety of carbohydrates will result.
Answer:
Sugars with different properties that can build a wide variety of carbohydrates will result.
Explanation:
This is the correct answer.This is because the arrangement of the monosaccharides units though the linking of the monomers with the glycosidic bonds via condensation reaction goes a long way to determine the orientation of the monosccharides and therefore the chemical properties displays.
Therefore when monosaccharides are linked by glycosidic bonds in different ways to form diasaccharidesa and polysacharrides,these macromolecueles display different chemical properties and physical properties from one another.
This is evident in cellulose((beta-glucose) whose 3-helix structure strengthened the wall of green plants.This orientation ensures that the hydrogen of -OH group is attached to the Oxygen of the same OH in the same molecule,or to that of another molecule.This formed hydrogen bond strong enough to form microfibrils which are held by fibres.
This is different from the structure of glycogen(from alpha 1,4 and 1,6-glycosidic bonds) despite the two been formed from monoscacharides. This is also evident in the structure of starch formed by alpha glucose
It is the orientation of the monomoers of the monosccharides in space that determines this different properties

Which of the following performs the phosphorus cycle A) Autotrophs C) Carnivore B)Heterotrophs D) Herbivore
Answer:
The autotrophs are the ones that perform the phosphorus cycle.
Explanation:
A is correct because the autotrophs are the organisms that are able to consume the inorganic phosphates, use them, and release parts of them in the other spheres, thus contributing to the phosphorus cycle.
B is not correct because the heterotrophs are not organisms that can process inorganic matter and produce their own food, instead, they are dependent on the autotrophs to do that.
C is not correct because the carnivores are not able to consume and process inorganic phosphates, with their food sources being based around the primary and secondary consumers.
D is not correct because the herbivores use the producers (autotrophs) as their food source, and they are not able to process inorganic phosphates on their own.
