olecular diagnostic techniques that can help diagnose hemoglobin disorders such as hemoglobinopathies and thalassemias include a) biochemical separation, identification, and quantification of mixture components b) separation of macromolecules and their fragments, based on their size and charge c) DNA amplification, hybridization, and nucleotide sequencing d) The use of specific monoclonal antibodies
Answer:
The correct answer is - a) biochemical separation, identification, and quantification of mixture components.
Explanation:
Most hemoglobin disorders can be diagnosed by molecular diagnostic techniques such as protein-based techniques like electrophoresis and chromatography. Protein-based methods can diagnose early thalassemia disorders and hemoglobinopathies but in the case of α-thalassemia may be masked in the presence of β-thalassemia.
Molecular genetic testing plays a very important role in the biochemical separation of molecules or components, identification, and quantification of individuals carrying thalassemia and hemoglobinopathies traits and other hemoglobin disorders.

An organism that creates its own food is called:
A) a producer
B)a consumer
C)a carnivore
D) a decomposer
Answer:
a
Explanation:
Answer:
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria.
Of the 23 pairs of chromosomes in any normal human cell, the first ____ pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's _____________ can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.
Answer:
Of the 23 pairs of chromosomes in any normal human cell, the first 22 pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's personality traits and cognitive abilities can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.
Explanation:
Chromosomes are small molecules that have the ability to carry all the genetic information needed to form a living being. These chromosomes are donated by an individual's parents and are used to form 23 pairs that determine all the internal and external characteristics of an organism. Among these 23 pairs, one pair will be responsible for determining the individual's gender, and the other 22 pairs will be responsible for the instructions that will make up the entire body and brain of the individual. Many scientists believe that chromosomes are responsible for even a part of a person's personality traits and that the genes they carry are directly related to the existence of psychological disorders.
The correct fillers for the given statements are: "22" and "personality and cognitive abilities"
Chromosomes are thread-like minute structures found in the nucleus of the plant and animal cells. These are the structures that help in transferring genetic information from one generation to another. Half chromosomes come from the mother and half come from the father's reproductive cells.
Humans have 23 chromosome pairs in their cells, one out of 23 pairs is responsible for the gender of the human embryo or child.the other initial 22 pairs are responsible for providing directions for an individual's body and brain development.On the basis of studies, many scientists say that almost half of the traits of personality and cognitive activities or mental processes to learn or acquire activities are due to chromosomes.Thus, the correct answers are : "22" and "personality and cognitive abilities"

DDT is an insecticide that accumulates in the fatty tissues of animals whose concentration increases with each link of the food chain. Which group of organisms is most likely to accumulate the highest concentration of DDT?
The question is incomplete, the complete question is shown in the image attached
Answer:
D
Explanation:
Pollutants tend to an increase in concentration in the fatty tissues of animals compared to the concentration of the same pollutant in the environment.
Also, tend to increase in the fatty tissues of organisms at each trophic level.
Hence, as a result of this, the highest concentration of the insecticide is accumulated by the organisms at the highest level of the food chain. So, the tertiary consumers accumulate the highest concentration of the insecticide.

DNA and RNA both use the same 4 types of nucleotides. Group of answer choices
True False
Answer:
Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are composed of nucleotides. A nucleotide is composed of three smaller molecules; a five-carbon, a phosphate group, and a nitrogenous base.
A DNA nucleotide contains the five-carbon sugar deoxyribose, a phosphate group, and one of four nitrogenous bases; adenine (A), guanine (G), cytosine (C), and thymine (T).
RNA contains the five-carbon sugar ribose, a phosphate group, and one of four nitrogenous bases; adenine (A), guanine (G), cytosine (C), and uracil (U). Uracil takes the place of thymine (T).
Both thymine and uracil pair with adenine.
So DNA and RNA nucleotides differ according to which five-carbon sugar is present, and whether the nitrogenous base thymine or uracil is present. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the nitrogenous base thymine, while RNA contains the nitrogenous base uracil.

Answer:
Explanation:
Gandhi who was assassinated about 20 years before King, is telling King all that happens when they kill your body is that what you have stood for and what you have left behind for your followers lives long after your death. Not to worry is the message: all will come out well when the methods you have used sink in to the leaders and followers you have left behind.
All that happens is that those who oppose you enough to kill you will think you are dead: you are not. Your legacy becomes stronger and stronger.

How does carbon dioxide travel in blood via dissolved form
Answer:
carbon dioxide is more soluble in water than oxygen and hence is mostly transported in the dissolved form in our blood.
Carbon dioxide can be transported through the blood via three methods. It is dissolved directly in the blood, bound to plasma proteins or hemoglobin, or converted into bicarbonate.
The majority of carbon dioxide is transported as part of the bicarbonate system.

The Osmosis Gizmo portrays a cell (red square) in a solution of purple solute particles dissolved in green solvent particles. Press Play ( ) and observe. Which particles can pass through the cell membrane
Answer: The particles that can pass through the cell membrane are the GREEN SOLVENT PARTICLES.
Explanation:
OSMOSIS can be defined as the thermal movement of solvent (water molecules) through a selectively permeable or semi-permeable membrane from a region of high concentration of the solvent to one where they are in low concentration.
The cell is bound by a membrane called plasma membrane. This membrane is selectively permeable and allows water and certain dissolved solvents to pass through it. As a result, the plasma membrane of the cell regulates the movement of materials between the cell and it's environment.
From the osmosis gizmo, it portrays a typical example of osmotic reaction occuring between a cell immersed in a solution of purple solute particles dissolved in green solvent particles. In order to maintain an osmotic balance between the cell and the solution surrounding it, the solvent (which is the green solvent particles) will move from the region of higher concentration to a lower region through the cell membrane

a.
nuclear fission
b.
photosynthesis
c.
oxidation of substances organic
d.
crossing-ove
Answer:
The correct answer is - C. oxidation of substances organic.
Explanation:
The major function of the mitochondria is to perform cellular respiration and produce energy in the form of ATP by oxidating organic molecules. All the process requires energy to be processed, however, the main and primary process that would disturb if by the destruction of the mitochondria occur which is the oxidation of glucose to convert it to pyruvic acid to generate energy.
The Krebs cycle that takes place in mitochondria and performs oxidation of organic molecules will also be disturbed and there will be no energy for any process.
