Hemophilia is an X-linked recessive condition in which blood does not clot properly. Queen Victoria of England had one allele for hemophilia. Most of her male descendants had the disorder, but few females had it. Why did hemophilia occur more frequently in Queen Victoria’s male descendants?

Answers

Answer 1

Answer:

Because hemophilia is an X-linked recessive condition.

Explanation:

As the problem states, hemophilia is an X-linked recessive condition.

Meaning that in Queen Victoria's female descendants (coded XX) which inherited the Queen's one allele, for hemophilia to appear in them it would be necessary to inherit another hemophillia-carrying allele from the father.The Queen's male descendants (coded XY) would always manifest hemophilia if they inherited the Queen's hemophilia allele, as they possesed only one X gene.

C. y + 5 = 3(x+3)
O D. Y-3 - (x+5)

Answers

Answer:

A. y + 5 = -3(x - 3)

Explanation:

Given the following data;

Points on the graph (x1, y1) = (3, -5)

Points on the graph (x2, y2) = (0, 4)

First of all, we would determine the slope of the equation of line;

Mathematically, the slope of a line is given by the formula;

[tex] Slope, \ m = \frac {Change \; in \; y-axis}{Change \; in \; x-axis} [/tex]

[tex] Slope, \ m = \frac {y_{2} - y_{1}}{x_{2} - x_{1}} [/tex]

Substituting into the formula, we have;

[tex] Slope, \ m = \frac {4 - (-5)}{0 - 3} [/tex]

[tex] Slope, \ m = \frac {4 + 5}{0 - 3} [/tex]

[tex] Slope, \ m = \frac {9}{-3} [/tex]

Slope, m = -3

Next, to find the point-slope equation of the line, we would use the following formula;

y - y1 = m(x - x1)

y - (-5) = -3(x - 3)

y + 5 = -3x + 9

y = -3x + 9 - 5

y = -3x + 4 = mx + c

What are three techniques that can be used to show that the electron transport chain is found on the matrix side of the inner mitochondrial membrane. Select all that apply.

Answers

Answer:

Explanation:

Step 1: Generating a Proton Motive Force

The hydrogen carriers (NADH and FADH2) are oxidised and release high energy electrons and protons

The electrons are transferred to the electron transport chain, which consists of several transmembrane carrier proteins

As electrons pass through the chain, they lose energy – which is used by the chain to pump protons (H+ ions) from the matrix

The accumulation of H+ ions within the intermembrane space creates an electrochemical gradient (or a proton motive force)

Step Two: ATP Synthesis via Chemiosmosis

The proton motive force will cause H+ ions to move down their electrochemical gradient and diffuse back into matrix

This diffusion of protons is called chemiosmosis and is facilitated by the transmembrane enzyme ATP synthase

As the H+ ions move through ATP synthase they trigger the molecular rotation of the enzyme, synthesising ATP

Step Three: Reduction of Oxygen

In order for the electron transport chain to continue functioning, the de-energised electrons must be removed

Oxygen acts as the final electron acceptor, removing the de-energised electrons to prevent the chain from becoming blocked

Oxygen also binds with free protons in the matrix to form water – removing matrix protons maintains the hydrogen gradient

In the absence of oxygen, hydrogen carriers cannot transfer energised electrons to the chain and ATP production is halted

Modelizar un ecosistema colocando los niveles tróficos y las relaciones en la red alimentaria

Answers

Answer:

Ejemplo ecosistema y su cadena trófica:  

- Ecosistema: llanura (campo de maíz)  

- Productor primario: plantas de maíz  

- Consumidor primario: Ratones

- Consumidor secundario: Aves rapaces

- Microorganismo descomponedor: bacterias  

Explanation:

En una cadena trófica o cadena alimentaria de un ecosistema, cada nivel obtiene la energía necesaria para sustentar la vida a partir del nivel inmediatamente anterior, mientras que los productores primarios son aquellos organismos que hacen ingresar la energía al ecosistema. Por otra parte, los descomponedores son organismos que se alimentan de los restos de animales y plantas, mediante su descomposición, obteniendo de ellos energía y materia hasta transformarlos en materia inorgánica. En el ejemplo arriba citado, las plantas de maíz representan los productores primarios los cuales producen energía y materia orgánica requerida para sustentar el ecosistema mediante el proceso de fotosíntesis. En segundo lugar, los ratones, como así también otros organismos herbívoros, representan los consumidores primarios los cuales conforman el segundo nivel trófico de la cadena alimentaria. En tercer lugar, los animales carnívoros que se alimentan de consumidores primarios (como por ejemplo, aves rapaces) representan el tercer nivel trófico, y así sucesivamente niveles superiores en el caso que existan depredadores mayores en el ecosistema. Finalmente, bacterias y otros organismos (por ejemplo, hongos, lombrices, algunos insectos, etc) representan los descomponedores los cuales se alimentan de restos orgánicos en descomposición, transformándolos de este modo en compuestos inorgánicos que ingresan nuevamente al ecosistema.

Why Darwin is known as father of evolution? Discuss how evidences against Darwinism led to formulation of modern evolutionary theory. Interpret its postulates in your words with relevant examples. (10 marks)

Answers

Answer:

Darwin was one of the greatest scientists who ever lived. He wrote the book 'The origin of species'. Darwin was known not only for the theory of evolution as we know it today, but also the foundation that biological sciences are based on. Darwin was very worried that people would reject his theory, so he collected a huge amount of evidence. He took evidence from the fossil record and from his own collections. He talked to animal breeders and animal collectors. He proved that the theory of evolution is based on the idea that all species are related and gradually change over time. His postulates is what gave him the title father of evolution

Postulates of evolution:-

1) Individuals within species are variable

2)Some of these variations are passed on to offspring

3)In every generation, more offspring are produced than can survive

4) The survival and reproduction of individuals are not random

The individuals who survive and go on to reproduce the most are those with the most favorable variation, and they are naturally selected.

Example:-

If an animal has to do the same task over and over again, it's body gradually changes to make the task easier. So if a deer reaches higher and higher into trees for food, day after day, it's neck will gradually stretch as it gets older.

If a deer's neck grows longer during it's lifetime, all it's babies will be born with long necks too.

A penicillin reaction is a life-threatening event. In those who are allergic to penicillin, the drug acts as a __________ that binds to blood proteins, causing a strong immune response.

Answers

Answer:

A penicillin reaction is a life-threatening event. In those who are allergic to penicillin, the drug acts as a hapten that binds to blood proteins, causing a strong immune response.

Explanation:

Low molecular weight chemicals can bind to antibodies, but cannot activate B lymphocytes by themselves (they are not immunogenic). To generate specific antibodies to these small chemicals, immunologists typically bind them to macromolecules prior to immunization. In these cases, the chemical is called a hapten. Penicillin G is a typical hapten that tends to covalently bind to lysine residues both in solution and in protein-bound cells. Penicillin is a drug that behaves as a hapten, since the beta-lactam ring under physiological conditions opens and reacts with the lysine residues of proteins, forming a complex that is the main antigenic determinant of penicillin and other beta-lactams and is capable of to stimulate responses mediated by antibodies or by T cells.

Warfarin acts by inhibiting the activity of the VKORC1 protein, which helps to produce functional clotting factors. There is a variant in the VKORC1 gene that lowers the dose of warfarin required for treatment, and individuals with this variant have increased risk of bleeding when they are treated with warfarin. This variant is found 1639 base pairs upstream of the translational start site. This variant likely:______.
a. decreases the activity of the VKORC1 protein.b. increases the activity of the VKORC1 protein.c. decreases expression of the VKORC1 gene.d. increases expression of the VKORC1 gene.

Answers

Answer:

The correct answer - c. decreases expression of the VKORC1 gene.

Explanation:

Mutation of Guanine nucleotide into Adenosine is the reason for this particular type of mutation. This mutation expresses the less expression of the VKORC1 protein.

The mutation results in a decrease in the affinity of the binding site of the transcription factor which causes less expression. Since the VKORC1 protein is less in the body so Warfarin doses are decreased  

Thus, the correct answer is - decreases expression of the VKORC1 gene.

which fundamental units are involved in force do step Wise ​

Answers

Force = ma

We know, the unit that the S.I. unit of mass is Kg.

We also know that a = (v - u)/t.

We know that v = d/t and u = d/t and the S.I. unit of t(time) is s.

We know that the S.I. unit of d(displacement) is m.

So, the S.I. unit of v is m/s and the S.I. unit of u is m/s and the S.I. unit of t is s.

So, the S.I. unit of a is m/s×s or m/s²

So, the unit of force is

(unit of m) × (unit of a)

= kg × (m/s²)

= kg.m/s²

=

[tex]kg \: m \: {s}^{ - 2} [/tex]

Or more simply,

F = ma

=> F = m{(v-u)/t}

Putting units,

Newton = kg[{(m/s) - (m/s)}/s]

=> Newton = kg{(m/s)/s}

=> Newton = kg(m/s²)

=> Newton = kg.m/s²

=> Newton = kg.m.(s^-2)
