Answer:
Less susceptible.
Explanation:
This organism would be less susceptible to the various germicides than a prokaryotic organism, such as bacteria because the form and structure of eukaryotic organism is different from the prokaryotic organism so the germicides no or less affected the eukaryotic organism so we can say that the the eukaryotic organism which is used in baking would be less susceptible to the various germicides than a prokaryotic organism.

True
False
Answer:
True
Explanation:
Meiotic recombination produces new genetic information in sister chromatids.This Happens During prophase I. Order the stages of prophase I chronologically: ____ Diplotene.-The synaptonemal complex dissociates; homologous pairs remain attached (chiasmata).
Answer:
See the answer below
Explanation:
The various stages of propase I of meiosis I in chronological order would be
1. Leptotene
2. Zygotene
3. Pachytene
4. Diplotene
5. Diakinesis
The leptotene stage is characterized by the thickening or condensation of the genetic material in the nucleus such that 'thick thread' structures is formed.
At the zygotene stage, the thickness advances and structures can be seen as chromosomes under the microscope. Homologous chromosomes are seen pairing up (synapsis) through the formation of synaptonemal complex to form tetrads or bivalents.
At pachytene, an exchange of chromosomal segments between synapsed homologous chromosomes occur in a process known as crossing over. The exchange point along the synapsed chromosomes are known as the chiasmata. After the crossing over, homologous chromosomes begin to separate but remains joined at the chiasmata.
At diplotene, the dissolution of the synaptonemal complex occur and homologous chromosomes still held together by the chiasmata begin to repel one another. The chiasmata becomes terminalized.
At Diakinesis, chromosomal condensation is completed and the cell is conditioned to progress to metaphase I of meiosis I.

Humans are know to have 46 chromosomes in each somatic cell. The domesticated cat, on the other hand, has 38 chromosomes in somatic cells. Given this predict the number of chromosomes found in the following cat cells:
Sperm cell:
Egg cell:
Daughter cell from mitosis:
Daughter cell from meiosis 1:
Daughter cell from meiosis 2:
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.
name two types of vaporization
Answer:
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.
Explanation:
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.
Identify two means by which meiosis results in genetically unique gametes, and explain why this is important.
Explanation:
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.

Describe how oxygen is transported in blood, and explain how temperature, pH, BPG, and affect oxygen loading and unloading.
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.
The kinetics analyses of an enzyme are measured as a function of substrate concentration in the presence and in the absence of 2mM inhibitor
[S] (microM): 3, 5, 10, 30, 90
Velocity (micromol/min) No Inhibitor: 10.4, 14.5, 22.5, 33.8, 40.5
Velocity (micromol/min) With Inhibitor: 4.1, 6.4, 11.3, 22.6, 33.8
Required:
What are the values of Vmax and Km in the absence of inhibitor? In its presence?
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.

Imagine that there is a mutation in the cyclin gene such that its gene product is nonfunctional. What kind of effect would this mutation have on a skin cell in the area of a cut
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.

Group of answer choices
perfusion

ventilation
diffusion
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.
