Answer:

take the reciprocal of the values as 1/S and 1/V and plot the values on lineweaver-burk plot.

so the re-arranged data is as following

1/S               1/V (no inhibitor)       1/V (with inhibitor)

0.333           0.096                       0.244

0.2              0.068                         0.156

0.1               0.044                         0.088

0.033          0.029                        0.044

0.011            0.024                         0.029

and the plotted lineweaver-burk plot with the equation of straight line would be....

where, first line represents the velocity of reaction with no inhibitor and second line represent the velocity in presence of inhibitor. X-axis has the substrate concentration as 1/S and y-axis has the velocity as 1/V.

as per the plot, equation of line on the lineweaver-burk plot, Y = mx + c, where c = 1/Vmax and m = Km/Vmax.

so solve for the given equations.

First, equation of line in the absence of inhibitor is Y = 0.23x + 0.021

so Vmax = 1/0.021 = 47.6 micromol/min

and Km/Vmax = 0.23, or Km = 0.23 x 47.6

Km = 10.95

Km do not have a unit, so 10.95 x 10-6 or as per your values round it up to 1 decimal point as 1.1 x 10-5

so value of Vmax = 47.6micromol/min and Km = 1.1 x 10-5 in the absence of inhibitor.

similarly, equation of line in the presence of inhibitor is given as Y = 0.67x + 0.021

so Vmax = 1/0.021 = 47.6 micromol/min

and Km/Vmax = 0.67

or Km = 0.67 x Vmax = 0.67 x 47.6 = 31.89

Km do not have a unit, so 31.89 x 10-6 or 3.1 x 10-5

so value of Vmax = 47.6micromol/min and Km = 3.1 x 10-5 in the absence of inhibitor.

Answer:

Sperm cell: 19 chromosomes

Egg cell: 19 chromosomes

Daughter cell from mitosis: 38 chromosomes

Daughter cell from meiosis 1: 19 chromosomes

Daughter cell from meiosis 2: 19 chromosomes

Explanation:

There are two major divisions that occur in living organisms namely: meiosis and mitosis. Meiosis is called a reduction division because it reduces the chromosomal number of offsprings by half while mitosis is called multiplication division because it maintains the same number of chromosome in the parent cell.

According to this question, a cat has 38 chromosomes in its somatic/body cells. It will possess the following chromosome numbers after the type of division:

- Sperm cell: 19 chromosomes because sperm are gametes formed via meiotic division, hence, 38 chromosomes are reduced by half i.e. 38/2 = 19.

- Egg cell: 19 chromosomes because egg cells are gametes formed via meiotic division, hence, 38 chromosomes are reduced by half i.e. 38/2 = 19.

Daughter cell from mitosis: 38 chromosomes because mitosis maintains the number of chromosomes as parent.

Daughter cell from meiosis 1: 19 chromosomes because the actual reduction from diploid (38 chromosomes) to haploid (19 chromosomes) takes place in meiosis 1 due to separation of homologous chromosomes.

Daughter cell from meiosis 2: 19 chromosomes because sister chromatids, which becomes individual chromosomes, are separated at this stage.

Albinism is a recessive trait where an individual does not produce the pigment melanin. Albinism is an autosomal disease where the gene which is expressed here is having albinism which is the cause of heterozygous condition.

What is the heterozygous ?

Heterozygous is the condition where the genes in the alleles are different to each other where one has a dominant character and one has a recessive character. The genotypes of the woman and man decide the genotype of the offspring.

The genotypes of the man and woman is heterozygous where the dominant once out of 3 will have the dominant traits for the albinism. The condition will have to be heterozygous as in the Ia Ii gene where the gene for the albinism   will be i gene.

The same genotype for the male where the Ib i gene in which i i the albinism carrying gene here the ii condition of the gene will express the albinism.

Answer:

Equalized air pressure.

Explanation:

The function of eustachian tube enables air pressure to be equalized between the outside air and the middle ear cavity. The eustachian tube also known as pharyngotympanic tube that connects the middle ear cavity with the nasopharynx. Eustachian tube is responsible for the aeration of the middle ear system as well as clears mucus from the middle ear into the nasopharynx. Opening and closing functions of the eustachian tube are is very important.

Explanation:

Solution :

The flow of oxygen in the blood is been transported by two ways :

1. in plasma 1.5%

2. bound to hemoglobin 98.5%

As the oxygen loads in the body, affinity of the Hb makes the oxygen loading very efficient in the blood. The Hb molecule gets saturated when all the 4 hemes are oxygen binded.

The decreased pH weakens the hemoglobin oxygen binding in the tissues.

Higher temperatures in the oxygen means a lower affinity and thus more oxygen is released and so the oxygen unloads.

Increase in the temperature, the BPG and the modification of the structure in the hemoglobin decreases the affinity for the oxygen and further enhances the unloading of the oxygen in the blood.

Answer:

The correct answer is - The cell would be unable to produce.

Explanation:

Cyclin is a protein that helps in cell division to complete the various stages. It has an essential function, however, cyclin does not play role in enzymatic reactions bit bind with cyclin-dependent kinase enzyme they form maturation promoting factors which can phosphorylate specific proteins and result in many different stages of the cell cycle.

Mutation in cyclin gene that did not allow to produce cyclin protein will cease the cell cycle and there would be no future daughter cell and the cell would not be able to produce.

Vaporization (or vaporisation) of an element or compound is a phase transition from the liquid phase to vapor. There are two types of vaporization: evaporation and boiling.

Answer:

The two types of vaporization are evaporation and boiling.

Evaporation takes place at the surface of a liquid such as a puddle drying up.

Boiling takes place below  the surface of a liquid and causing bubbling like a pot of water on a hot stove.

Meiosis is beneficial as it produces gametes that are genetically different to the parent cell, and when the gametes combine the offspring produced is made from combination of genes from both mother and father. The offspring is genetically unique, there is no other organism on the Earth with the exact same DNA sequences on their chromosomes.

The Milky Way galaxy is part of a group of galaxies called the Local Group. Three characteristics that I learned about our galaxy group is The Milky Way is a large barred spiral galaxy, they come in a variety of shapes and sizes, and  it appears as a milky band of light in the sky when you see it in a really dark area.

Explanation:

Edmentum

The Milky Way galaxy is a member of the Local Group of galaxies named Laniakea . The Milky Way is a massive barred spiral galaxy and  can be seen as a milky band of light.

The Milky Way galaxy is a massive, flat, disk-shaped collection of stars, gas, and dust that spans around 100,000 light-years and is several thousand light-years thick.

The Milky Way galaxy contains every star that we can see with our unaided eyes. The Andromeda Galaxy is the only celestial object visible in the night sky with unaided eyes that is not part of the Milky Way.

It is estimated that the Milky Way is 12 billion years old.

Thus, Milky Way is the galaxy we live in amongst others.

Answer:

ventilation

Explanation:

Breathing, also known as ventilation, is the process of moving air or water in order to facilitate the gas exchange between the external and internal (body) environment, mostly to eliminate carbon dioxide (CO2) and bring in oxygen (O2). For example, fish are aquatic animals that need to run water over their gills to get the O2 that they need to survive (gills are organs that create a large surface area for ventilation). Moreover, insects ventilate their tracheal system to get O2. Finally, terrestrial vertebrates (i.e., amphibians, reptiles, birds, and mammals) use organs called lungs to exchange O2 and CO2 between their cells and the external environment.
