Answer AND Explanation:
The fact that the father has blood group A with rhesus factor positive and mother blood group B with rhesus factor, provides a possible scenario for Tamari to both the genes from the parents thus her blood is AB. Since both parents are rhesus positive, then Tamari's rhesus is likely to be positive. Gene A and B have equal degrees of dominance that is they are codominant and will both express themselves when present together as in both AB blood group.
Final answer:
Tamari's AB+ blood type comes from inheriting an A allele from her father and a B allele from her mother, given her mother's B+ blood type. Her father also contributes the Rh factor, making Tamari Rh positive (Rh+). This explains the AB+ blood type through the principle of codominance in the ABO blood group system.
Explanation:
The blood type of an individual is determined by the type of antigens present on the surface of their red blood cells. We can explain Tamari's blood type AB+ in the context of Mendelian genetics. The ABO blood group system is based on codominance, where two different alleles can be expressed at the same time.
According to the problem, Tamari has blood type AB+, and her mother has blood type B+. For Tamari to have an AB blood type, she must have inherited one A allele from one parent and one B allele from another. Since Tamari's mother has blood type B+, she would have either the genotype IBIB or IBi (where "i" stands for the O allele).
Tamari's AB+ blood type suggests one of her parents must have an A allele to contribute. This implies her father must provide the A allele, as well as the Rh positive factor since Tamari is Rh positive (Rh+).
Thus, Tamari's mother could be either genotype IBi or IBIB, and her father must have an A allele (either IAIA, IAi, or IAIB if he is type AB) and an Rh positive allele.
Lastly, for a type AB individual such as Tamari, she can only donate blood to others who are type AB, making her a universal recipient but not a universal donor. She has both A and B antigens
in the early days of the solar system, many planetesimals orbited the Sun. Theory has it that one large planetesimal the
size of Mars struck a glancing blow to the molten Earth. How did this event contribute to the formation of the Moon?
This event led to the breaking away of a part of earth and the part was held on by earth’s gravity and this part became the moon.
Explanation:
The formation of moon was after the formation of the earth. In the initial years of the formation of earth it was affected by several asteroid hits and comets. Small planets referred to as planetesimals also kept continuously affecting the earth. Before 4.5 billion years ago a planetesimal which was about the size of Mars hit earth.
This hit led to the breaking away of a part of earth. The part which was sent to space by the hit was caught by the gravity of the earth and the part started orbiting around the earth. The similarity of the rocks in moon to that of earth is attributed to the fact that moon was actually formed from earth.
The moon and earth keeps influencing each other. The moon’s effect reduced the speed of earth’s rotation and the moon keeps moving away from the earth due to the influence of earth.
Answer:
Molten rock broke off from Earth following the impact. The rock coalesced (gathered) into a ball, which formed the Moon.

Final answer:
DNA fingerprinting is the technology used to identify individuals for paternity testing, criminal investigations, and missing person identification by analyzing variations in DNA sequences.
Explanation:
The DNA technology used to identify a correct father, a suspect using a small sample of evidence, and a missing person is commonly known as DNA fingerprinting or genetic fingerprinting. This technology analyses the variability in DNA sequences to match individuals with biological samples. For paternity tests, technicians compare DNA sequences from the mother, child, and potential father. In forensic cases, geneticists compare the DNA from crime scene evidence to that of suspects to find a match.
DNA fingerprinting is incredibly powerful because it utilizes the parts of human DNA that show high variability, meaning those sequences that are likely to be different in each individual, except for identical twins. The process typically involves amplifying a specific region of DNA, often using a method called Polymerase Chain Reaction (PCR), and then separating and analyzing the DNA fragments by gel electrophoresis.
Furthermore, the use of restriction enzymes allows DNA molecules to be cleaved at specific points, making the analysis more precise. DNA collected from various sources such as hair, blood, or saliva, can uniquely identify individuals, establishing relationships or linking suspects to crime scenes based on their unique genetic makeup.

How does the conservation of matter relate to the process of digestion?
The conservation of matter is related to the process of digestion in the following way:
When food is eaten it is digested by converting it into smaller particles. These smaller particles are then digest and gives the energy to our body. Thus, we get energy by eating or digesting the food. Hence, we can say that mass neither created nor destroyed but it change one form to another, just like the form from food to energy.
Law of Conservation of Matter:It states that matter cannot be created or destroyed. In a physical change, substances can change form, but the total mass remains the same.
Find more information about Digestion here: brainly.com/question/17069676
The conservation of matter relates to the process of digestion in that the mass of the food ingested is equal to the mass of the substances produced after digestion, which include waste products and the nutrients absorbed by the body. This principle is a demonstration of the law of conservation of mass, which states that matter cannot be created or destroyed in an isolated system.
During digestion, the food we consume is broken down into smaller molecules that can be absorbed by the body. These molecules include carbohydrates, proteins, fats, vitamins, and minerals. The digestive system uses mechanical and chemical processes to convert the food into a form that can be absorbed into the bloodstream.
The mass of the food ingested is conserved throughout the digestive process. The nutrients absorbed by the body contribute to growth, repair, and energy production. The waste products, which include undigested parts of the food and substances produced during the digestive process, are eliminated from the body.
If we were to account for all the matter that enters the digestive system and compare it to all the matter that leaves it (either as absorbed nutrients or as waste), we would find that the total mass remains constant. This is a practical application of the conservation of matter in a biological context.
In summary, the conservation of matter in the context of digestion means that the total mass of ingested food equals the sum of the mass of the nutrients absorbed into the body and the mass of the waste products excreted. This is a clear example of how the law of conservation of mass applies to living organisms and their metabolic processes.

Why is anaerobic respiration energetically less efficient than aerobic respiration?
The aerobic respiration process uses a respiratory electron transport chain, while anaerobic respiration uses a molecular electron transport chain.
Anaerobes use less oxidizing substances like sulfate or nitrate during the electron transport chain so less energy is released per oxidized molecule.
Anaerobes use only oxygen during the electron transport chain, while aerobes use both oxygen and carbon dioxide which results in a more efficient process.
Anaerobes' terminal electron receptors have larger reduction potentials than O2 meaning that more energy is released per oxidized molecule.
Answer:
Anaerobes use less oxidizing substances like sulfate or nitrate during the electron transport chain so less energy is released per oxidized molecule.
Explanation:
Anaerobes use fewer oxidizing substances such as sulfate or nitrate during the electron transport chain, so less energy is released per oxidized molecule. This is because unlike aerobic respiration, in the anaerobic process there is no need for oxygen and glucose will be formed from the body's own food or reserves.
In this process of metabolic function there is no presence of oxygen and the energy comes from the ATP molecule, formed by the adenine nitrogen base, sugar, and three phosphates. This connection, when necessary, is broken for the release of energy.
In this case, glucose will originate from food or reserves created by the body itself. Thus, in the cell cytosol, this substance undergoes several reactions, caused by various enzymes, and then pyruvate, also used in aerobic respiration, will be generated. During the anaerobic respiration process, the ADP (adenosine phosphate) molecule receives a phosphate. After this, ATP formation occurs.
Final answer:
Anaerobic respiration produces only 2 ATP per glucose molecule due to the use of less efficient final electron acceptors, such as sulfate or nitrate, compared to oxygen used in aerobic respiration, which can yield up to 38 ATP. This makes anaerobic respiration significantly less efficient in energy production.
Explanation:
Anaerobic respiration is energetically less efficient than aerobic respiration because it yields far less ATP per glucose molecule. Anaerobic respiration produces only 2 ATP molecules, whereas aerobic respiration can produce up to 38 ATP molecules. The key difference is the presence of oxygen. In aerobic respiration, oxygen serves as the final electron acceptor in the electron transport chain and allows for a more complete oxidation of glucose, leading to the production of a larger amount of ATP through oxidative phosphorylation.
During anaerobic respiration, the lack of oxygen means that alternative less oxidizing substances like sulfate or nitrate serve as the final electron acceptors. These have lesser reduction potentials compared to oxygen, which results in far less energy being released during their reduction. The result is a significantly decreased yield of ATP from the process of electron transport and phosphorylation. Additionally, the electron transport chain in anaerobes can be less efficient due to different electron carriers that produce smaller electrochemical gradients.
The inefficiency of anaerobic respiration impacts organisms heavily; to obtain the same amount of energy as aerobic respiration, a much larger quantity of glucose must be metabolized. This is a critical limitation for anaerobic organisms and is a significant factor in the dominance of aerobic organisms in most environments on Earth.

Explanation:
- Proteins
The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell. Sequences of DNA make up genes which can have different forms called alleles and comprise the genotype. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins. These proteins, when expressed, are referred to as an organism's phenotype.
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.
Large chains of monomers form biological macromolecules which carry out many essential functions in the body these can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P).
Proteins are structural support molecules comprised of long chains of amino acids joined via peptide (CONH) bonds; these are 20 specific units that are arranged into several macromolecules. Amino acids are absorbed through digestion and are incorporated into the body’s cells to make up organs muscles signal molecules and an alternative energy source.

Explain how an Enzyme works using the terms from 1-5
The enzyme grabs onto the substrate in a special area called the active site.
The active site is an area of the enzyme that fits around the substrate.
Catalysis is when the substrate is changed.
The enzyme lets go, returns to normal and is ready to do another reaction.
The substrate is no longer the same, it is now called the product.
How does enzyme work?
An enzyme functions through a process called catalysis, where it facilitates chemical reactions in living organisms. The enzyme's active site, a specific region with a unique three-dimensional shape, binds to a substrate, which is the molecule the enzyme acts upon.
This binding creates an enzyme-substrate complex, allowing the enzyme to catalyze the conversion of the substrate into a product. The active site provides a specialized area for the substrate to undergo the chemical changes, ensuring specificity and efficiency in the reaction. Ultimately, the enzyme remains unchanged after the reaction.

How many chromatids are there in one duplicated chromosome
Answer:
There are two chromatids in one duplicated chromosome.
Explanation:
Before any cell undergoes the process of cell division, the chromosomes of the cell duplicate themselves. This results in the formation of two chromatids which are known as the sister chromatids. The chromatids are joined together from the centre at a position called the centromere. The chromatids contain the same kind of DNA in them. Chromatids are often confused with homologous chromosomes. They are not homologous chromosomes, they are the copy of a chromosome.
In biology, a duplicated chromosome contains two identical copies (chromatids) that are attached via a structure known as the centromere.
Explanation:In biology, a duplicated chromosome has two identical copies (chromatids) attached to each other by a structure called the centromere. Hence, we can say that in one duplicated chromosome, there are two chromatids. This state typically exists after DNA replication, a process during the S phase of the cell cycle, and before cell division, when chromatids separate into each new cell.

Cell theory explains the main parts of a cell and how cells reproduce.
Cell theory states that non-living matter can make cells that becoming living things.
The answer is the 2nd sentence. This is because all living things come from other living things, due to reproduction, which is what the cell theory is based off of.
Cell theory states that all living things are made of cells that come from other living cells is statement that best describes cell theory.
The cell theory, applied to biology, is responsible for identifying and describing the properties of cells, holding that all living things can be made up of a single cell or several.
The cell is considered the basic unit of life, which through a process in which cells are split or divided, gives way to the existence of new cells.
This indicates that every cell originates from the division of another cell and therefore contains the necessary genetic information within themselves.
Therefore, we can conclude that the cell theory indicates the cell as a unit of origin, being the basic unit of life, the only unit from which others can be born and being necessarily from a pre-existing one.

Monosaccharides such as glucose, fructose, and galactose are all hexose sugars with six carbon atoms, and both ribose and deoxyribose are pentose sugars with five carbon atoms, making all of them simple sugars.
Monosaccharides are simple sugars and the most common types are glucose, fructose, and galactose. These are all hexose sugars because they contain six atoms of carbon. Other important monosaccharides in the body are ribose and deoxyribose, which are pentose sugars having five atoms of carbon. The structural difference between glucose and galactose is highlighted by the position of the hydroxyl (OH) group.
Referring to the review question, fructose, glucose, and galactose are monosaccharide. All three are monosaccharides with six carbon atoms (C₆H₁₂O₆) and abide by the general formula for carbohydrates, which often have multiple hydroxyl (-OH) functional groups. Note that ribose (C₅H₁₀O₅) and deoxyribose (C₅H₁₀O₄) are also monosaccharides but contain five carbon atoms.

Animal feces would be classified as which type of water pollutant?
Answer:
waste contamination
Explanation:
dont cheat or i will hunt you down with my pack of wolves
Final answer:
Animal feces is a biological water pollutant that can introduce infectious agents into water bodies, leading to diseases such as typhoid fever and hepatitis. It is a significant concern when waste management systems are inadequate, especially in areas with large livestock farms.
Explanation:
Classification of Animal Feces as a Water Pollutant
Animal feces is classified as a biological pollutant when considering the types of water pollutants. These pollutants primarily consist of pathogens such as bacteria, viruses, and parasitic worms, which can originate from the improper treatment and disposal of human and animal waste. As a biological water pollutant, animal feces contributes to the contamination of water resources by introducing infectious agents into water bodies.
Moreover, the waste from animal feces can lead to diseases in humans, such as typhoid fever, cholera, and hepatitis. The presence of such biological materials in water can be mitigated through methods such as chlorination, ozonation, and by improving the treatment of sewage before it is discharged into water bodies. In cases where animal feces from livestock farms are not managed correctly, it can add to the issue of water pollution, especially if waste is stored in lagoons that may leak, contaminating surrounding water resources.
An injury to which region would interfere with the sleep-wake cycle?
An injury to the suprachiasmatic nucleus (SCN) in the hypothalamus would disrupt the sleep-wake cycle, as it regulates circadian rhythms by controlling melatonin secretion in response to light and darkness.
Explanation:An injury to the suprachiasmatic nucleus (SCN) within the hypothalamus would interfere with the sleep-wake cycle. The SCN acts as the body's biological clock, influencing circadian rhythms by responding to light cues and regulating the secretion of melatonin. Melatonin levels are increased by darkness, promoting sleep, and decreased by light, promoting wakefulness. Disruptions in these processes can lead to difficulties with sleeping patterns such as insomnia or excessive sleepiness during the day.
Additionally, other brain areas that regulate sleep, such as the thalamus and pons, also contribute to maintaining normal sleep-wake cycles. Therefore, injuries to these areas might result in sleep disorders or disturbances in circadian rhythms.
Final answer:
An injury to the hypothalamus or the pons could interfere with the sleep-wake cycle.
Explanation:
The sleep-wake cycle is controlled by multiple brain areas, including the thalamus, the hypothalamus, and the pons. An injury to any of these regions can interfere with the sleep-wake cycle. For example, damage to the hypothalamus, which contains the suprachiasmatic nucleus (SCN) - the biological clock of the body - can disrupt the circadian rhythms that regulate sleep. Damage to the pons can interfere with the regulation of rapid eye movement (REM) sleep. Therefore, an injury to either the hypothalamus or the pons could interfere with the sleep-wake cycle.
