2a. Which curve was generated using an enzyme taken from a bacteria that lives in hot springs at temperatures of 70OC or higher and explain why? b. The optimum temperature for enzyme 1 (curve 1) is approximately?c. Which curve was most likely generated from an analysis of an enzyme from a human stomach where conditions are strongly acidic and explain why?
Answers
In this case, we need to remember how we detect an optimum in enzyme activity. As the reaction accelerates and reaches the slope the optimum has been reached, when conditions keep changing after the optimum, the curve descends.
2a, here we have a thermophilous bacteria that lives at a high temperature so is natural that the optimum of an enzyme of this bacteria be at high temperatures as is the case of curve 3.
b. For this curve we have a slope around 30°C so this is the optimum temperature.
c. Here the curve is generated with a pH range, and the dynamics is the same that with temperature. The human stomach has a pH around 2, so the most likely slope that corresponds with human enzyme is curve 4.

In order for lactose to be digested to produce the two monomers that can be digested bythe human body, the molecule has to undergo a hydrolysis reaction. During this processwhat occurs to this disaccharide?
Answers
Lactose is a disaccharide, which means that it is formed by two carbohydrate or sugar monomers. In this case, the two monomers that form lactose are glucose and galactose.
When lactose is digested by the human body, what happens is that the bond between the monomers is broken, releasing glucose and galactose which can be absorbed by the human body.

Blood type in humans contains multiple alleles.A male with type A blood and the genotype AO mates with a female with type B blood and thegenotype BO. What are the possible blood types of their offspring?
Answers
To determine the possible blood types of the offspring you have to create a Punnet square crossing the genotypes of the parents.
The male parent has a blood type A, his genotype is AO, which means that his gametes can carry the alleles "A" or "O"
The female parent has a blood type B, his genotype is BO, which means that her gametes can carry the alleles "B" or "O"
Cross the alleles of the parents to determine the possible genotypes of their offspring:
The genotypes of the offspring and their phenotypes are:
AB → Blood type AB
AO → Blood type A
BO → Blood type B
OO → Blood type O
All of the given options are possible blood types of the offspring so the correct answer is All of these.

Answers
To answer this we need to remember the pH scale, as lower is the numbe the compound is more acid, mmeanwhile, if the number ishigher wweare talking of a base, it ranges from 10to 14, being l0 the most acid, 7 neutral and 14 strongest base. Also, we must not forget that the pH scale is on a logarithmic scale (base 10) which means that each level is 10 timeshhigherthatn the previous level, so if we have a 13 pH level we are talking of a very strong base, therefore, the correct answer is option e.

68% Baryonic Matter, 5% Dark Matter, 27% Dark Energy
95% Baryonic Matter, 2% Dark Matter, 3% Dark Energy
5% Baryonic Matter, 27% Dark Matter, 68% Dark Energy
0% Baryonic Matter, 0% Dark Matter, 100% Dark Energy
Answers
According to the scientists the correct percentage amount is about ~68% dark energy, ~27% dark matter, ~5% baryonic matter.
What is Dark Energy, Dark Matter and Baryonic Matter?
A hypothesized energy known as dark energy behaves like the antithesis of gravity by exerting a negative, repellent pressure. It has been proposed to explain the observable characteristics of far-off type Ia supernovae, which reveal an accelerated phase of the universe's expansion.Considered to make up about 85% of the universe's matter, dark matter is a hypothesized type of matter. The reason why dark matter is referred to be "dark" is because it does not appear to interact with the electromagnetic field. As a result, it cannot be detected because it does not emit, absorb, or reflect electromagnetic radiation.Dark matter made of baryons is referred to as baryonic dark matter in cosmology and astronomy. It is unlikely that all of the dark matter in the universe is baryonic. Baryonic dark matter is invisible through its radiation emissions, but its presence can be inferred from the gravitational effects on visible matter.
Scientists have calculated the universe's makeup as follows: 68% dark energy, 27% dark matter, and 5% normal matter. They did this by fitting a theoretical model of the universe's composition to the total set of cosmological observations.

if a diploid cell contains 14 pairs of chromosomes for a total of 2n=28, how many chromosomes will be in the resulting products of cellular division if the cell undergoes: mitosis?
meiosis?
Answers
The number of chromosomes that will be in the resulting products of cellular division if the cell undergoes mitosis is 28 and 14 for meiosis.
What is mitosis?Mitosis is the division of a cell nucleus in which the genome is copied and separated into two identical halves. It is normally followed by cell division.
Meiosis, on the other hand, is a cell division of a diploid cell into four haploid cells, which develop to produce gametes.
Mitosis is also called duplication division because the number of chromosomes in the parent cell does not change in the daughter cells. However, in meiosis, the chromosome number is reduced by half in the daughter cells.
According to this question, a diploid cell contains 14 pairs of chromosomes for a total of 2n = 28 chromosomes. This means that mitosis will result in 28 chromosomes while meiosis will result in 14 chromosomes.

Answers
Endoplasmic reticulum is a membrane system forming a series of sacs in eukaryotic cells. It has many functions, including the synthesis and transport of proteins. There are two types of endoplasmic reticulum with different structures, as follows:
1) Rough endoplasmic reticulum - its sacs are convoluted but flat, contiguous with the nuclear membrane. Its outer surface is studded with ribosomes, which gives it the rough appearance.
2) Smooth endoplasmic reticulum - its sacs are tube-like structures and they are located near the cell periphery. Sometimes these tubules branch, forming a reticular network wit.

Which of the following is an Incorrect match?a. larynx - containsvocal cordsb. pharynx - connects nasal and oralcavity to larynxc. sinuses - remove dust particles d. glottis - opening to the larynx
Answers
- The larynx is a part of the respiratory system, it connects to the pharynx and the trachea, ait allows the air to pass from the throat through the trachea directly to the lungs.
It is in this structure where the vocal cords are found.
- The pharynx, also called throat, connects the mouth to the esophagus and also contributes to breathing and phonation because it connects the nasal cavity, the Eustachian tubes, and the larynx with the buccal cavity.
- The function of the sinuses is to increase the contact surface of the air with the epithelium of the nasal cavity, which allows it to humidify and warm the inhaled air. They also play a role in phonation.
These structures help reduce the relative mass of the skull, thus decreasing its weight, provide "shock resistance" in case of injury, and isolate sensitive structures from rapid temperature changes occurred during inhalation.
- The glottis is the space between the pharynx and larynx.
The only match that is incorrect is c. sinuses - remove dust particles
