a) type A
b) type B
c) type O
d) typre AB
Answers
Answer:
c) type O
The woman has AB type blood group which means, gametes will be carrying the alleles of type A or B blood group and if the father has type O blood group the gametes will be carrying the gene which is recessive to both A and B.
It clearly refers to the child's blood group being either A or B.
Hence, c) type O is the correct option.

1. Glucose will react with oxygen in a laboratory setting using a combustion chamber. The reaction is exergonic, with the release of a large amount of energy in the form of heat and the production of carbon dioxide and water according to the following chemical equation:
C₂H₁2O6 + 60₂-6CO₂ + 6H₂O G = -686 kcal/mol
Glucose can also be incubated with cells that completely oxidize glucose, according to the same net chemical equation and with the same quantity of energy release. However, glucose oxidation in cells occurs during a series of steps, rather than in one step like the combustion reaction taking place in a lab. The diagram below shows these steps in terms of the free energy change at each step, as well as the input and output of ATP, NADH, and FADH, at different stages of the process. Free energy change and input/output during glucose oxidationa. A coupled reaction is a pair of reactions occurring together in which the energy released by one reaction is used in bond formation in the second reaction. For example, glycolysis and pyruvate processing form a coupled reaction.
Explain how coupling reactions allows a cell to capture the free energy of glucose oxidation rather than allow it to escape to the environment in the form of heat. Describe how this process affects other reactions in the cell. (3 points)

Answers
a. Coupling reactions capture energy of glucose oxidation for ATP production, preventing energy loss as heat. This process affects other reactions by supplying ATP, a universal energy currency, to drive cellular processes.
b. How are the enzymes and regulatory mechanisms involved in glucose oxidation conserved across different species, and what adaptations exist for energy metabolism variations?
In a laboratory setting, glucose reacts with oxygen in a combustion chamber. The reaction is exergonic and results in the release of a significant amount of energy in the form of heat, with the production of carbon dioxide and water according to the given chemical equation. A scientific question that a scientist might ask about how these processes are conserved across phyla is how the enzymes involved in these reactions are conserved across different phyla.Given that the process of cellular respiration is conserved across phyla, it follows that the enzymes involved in the reactions are conserved as well. Enzymes are proteins that catalyze chemical reactions, making them occur more quickly and with a lower activation energy than they would otherwise. Given the importance of these reactions, it is likely that the enzymes involved in the reaction are conserved across different phyla of organisms. For instance, the enzyme glucose oxidase is present in many different phyla and is responsible for the breakdown of glucose into carbon dioxide and water.For more such questions on Glucose:

Answers
Lacy wants to design an experiment that will show ovary part of a tomato flower grows into the tomato fruit.
What is ovary for plant?The female reproductive organ present in flowering plants is the ovary. It is present in the flower's gynoecium. It is a portion of the pistil that holds the ovules and is located near the base of the sepals and petals. A single carpel or numerous carpels joined together can form the pistil.
Ovaries, as we know, are an essential component of the plant's female reproductive system. Well, the ovaries are where pollen is kept before developing into ovules and ultimately seeds. These seeds then germinate, causing the ovaries to grow and convert into fruits.
Even though the blooms are self-fertile, the pollen is nevertheless moved to the female half of the blossom by wind and the buzzing of bees' wings. The young tomato grows after fertilization, when the petals and stamens fall off.
So, Lacy will show ovary part of a tomato flower grows into the tomato fruit.

Explanation:
For example:
Let us take an expression y=3x+1, where x has some given values { let's assume x lies between 0 to 100}
so we can see that the value of y is depending upon the value of x ,as for every different value of x we will get a different value of y. So we can say that y is a dependent variable.
On the other hand, x doesn't depend on y as its values are already mentioned or specified so it's an independent variable.

Molecular clocks are another source of empirical evidence that scientists collect to support evolutionary theories. Explain why it is necessary to usemultiple lines of empirical evidence to support theories of common ancestry and biological evolution. Include information from the reading, previouslessons, and scientific reasoning to support your claim.
Answers
Evolutionary theories are the flexible equivalent of species variability. To evaluate and support these theories, certain molecular clocks are used to know the relationship of species. These are done by considering the variations of every species' sequences of DNA. It is relevant to know the evidence that all living things contribute identical biochemical building blocks. Common ancestry and biological evolution is thereby supported by evidence regarding differences of structures. Homologous structures explains the same ancestry. Analogous structures, on the other hand, explains that the presence of identical features is the outcome of identical selective pressures.

Phenotypic ratio of di-hybrid cross is as follows:
Tall/Green : Tall/Yellow : Short/Green : Short/Yellow = 9 : 3 : 3 : 1
What is a dihybrid cross?A Dihybrid cross is a cross between two individuals with two observed traits controlled by two different genes. This describes a mating experiment between two organisms that are identical hybrids for two traits. Hybrid organisms are heterozygous, meaning they have two different alleles at a particular genetic position or locus. Dihybridization was initially valuable as an experimental test of Mendelian laws, showing that each trait can be inherited independently according to Mendelian rules. It has since become an important tool for mapping genes to chromosomes and elucidating how genes can interact to determine phenotypes.
The phenotypic ratio of a dicross in a standard Mendelian experiment is 9:3:3:1. In this case, her two pairs of alleles are grouped separately into gametes.

Heart cells produce the protein cardiac myosin, which is critical in allowing for muscle contractions of the heart. Liver cells do not produce cardiac myosin.
Which statement explains this difference between heart cells and liver cells?
Heart and liver cells express different genes.
Heart cells rely on , R N A, , while liver cells rely on , D N A, .
Heart cells contain different genes from liver cells.
Liver cells destroyed the gene for myosin, but heart cells did not.
Answers
The most accurate statement that explains the difference between heart cells and liver cells in terms of their production of the protein cardiac myosin is "Heart and liver cells express different genes."
In multicellular organisms, different cell types have specific functions and characteristics that are determined by the genes they express. Genes are segments of DNA that contain the instructions for producing specific proteins. Each cell type expresses a unique set of genes that enable them to carry out their specialized functions.
In the case of heart cells and liver cells, they have different gene expression profiles. Heart cells specifically express the genes responsible for producing cardiac myosin, a protein essential for the contraction of the heart muscle. This allows the heart to effectively pump blood throughout the body.
On the other hand, liver cells do not express the genes for cardiac myosin production, as the liver has different functions unrelated to heart muscle contraction. The statement that heart cells contain different genes from liver cells is essentially expressing the same idea. Heart cells and liver cells have distinct gene expression patterns, leading to the production of different proteins and ultimately different cellular functions.
Both heart cells and liver cells utilize DNA as the genetic material that contains the genes responsible for protein production. RNA molecules are transcribed from DNA and play a crucial role in protein synthesis, but the distinction between heart and liver cells lies in the specific genes they express, not the reliance on different genetic materials.

How would transcription be affected if a gene that needed to be expressed was missing its promotor?
Answers
Answer:
it can't be used to make a protein in that cell.
Explanation:
If a gene is not transcribed in a cell, it can't be used to make a protein in that cell. If a gene does get transcribed, it is likely going to be used to make a protein (expressed). In general, the more a gene is transcribed, the more protein that will be made.
The transcription is affected as when the gene has not been transcribed the protein will not make. When a gene is transcribed, protein synthesis can happen.
What is gene transcription?Gene expression begins with transcription. To create an RNA molecule, the DNA sequence of a gene must be copied. RNA polymerases, which join nucleotides to create an RNA strand, carry out transcription (using a DNA strand as a template).
A gene cannot be used to produce a protein in a cell if it is not transcribed there. If a gene gets transcribed, it will probably be used to produce a protein (expressed). In general, more protein will be produced the more a gene is transcribed.
Therefore, the transcription is impacted since the protein cannot be produced if the gene is not transcribed. Protein synthesis can take place when a gene is transcribed.

In the graph above, which letter represents the activation energy (EA) of a reaction without an enzyme and why?
ANSWER: CORRECT (SELECTED)
X; the activation energy (EA) is greater in an uncatalyzed reaction
EXPLANATION:
The X label on the graph represents a larger EA "hump" (as compared to Y). The increased steepness of this hump is due to the lack of an enzyme, making this an uncatalyzed reaction.
Answers
The activation energy of the reaction without an enzyme is represented as X.
What is activation energy of a reaction?Activation energy of a reaction is the minimum energy that reactant molecules must possess in order to effectively collide to form products,
The activation energy of a reaction depends on the bond energies of the reactants.
Given an energy profile diagram, the activation energy is represented as EA.
In the diagram, the activation of the reaction without an enzyme is X because it the activation energy of an uncatalyzed reaction is greater than the activation energy of a catalyzed reaction.
