Imagine a newly discovered biological molecule that is mostly hydrophobic in its structure. This new molecule will most likely be classified as a___________.

Answer:

Archaea

Explanation:

Three main domains exist according to classification, two of these domains are characterized to contain organisms that do not have a membrane bound nucleus, in other words, their single circular genetic material (DNA) is not housed by a nucleus. Instead, the naked DNA is found localized to a central region in the cytoplasm called NUCLEOID. These domains are bacteria and archaea domains and they are termed to be PROKARYOTIC.

These domains also lack membrane bound organnelles i.e their few present organnelles are not bounded by lipid layer. Archaea and Bacteria both have cell walls but what makes up the cell wall is different in both organisms. The organism will most likely be an archaea because it portrays its characteristics being that, an archaea is a unicellular prokaryotic organism with a cell wall. It also has the ability to thrive in extremely harsh conditions like the hot thermal vent described in the question.

The single-celled organism described is most likely a member of the Archaea domain due to its lack of a nucleus and the presence of a cell wall. Archaeans are known to thrive in extreme environments.

The single-celled organism you described, that has been isolated from a hot thermal vent in the deep sea and possesses a cell wall but lacks a nucleus, is most likely a member of the Archaea domain. The major characteristics of the Archaea include a lack of nucleus or other membrane-bound organelles, presence of unique lipids in their cell membrane, a distinctive cell wall, and their ability to thrive in extreme conditions, like high temperatures.

Answer:

d. helps regulate blood glucose

Explanation:

The insulin hormone is secreted by beta cells of the endocrine portion of the pancreas. Insulin is released in response to raised blood glucose levels. The function of this hormone is to make the body cells to take up the glucose from the blood. It specifically targets the liver and muscle cells and makes them absorb glucose from the blood. The absorbed glucose is stored in the form of glycogen in these cells and the blood glucose levels are restored to the normal range.

Answer:

High specific heat.

Explanation:

Water is able to maintain the temperature of living organisms because it has highest specific heat. Specific heat is a physical property of matter. If specific heat is high then the matter does not get heated easily but once it is heated it does not cool down easily either. In short we can say that water can easily resist temperature changes because it has very high specific heat.   This property plays a great role in maintaining the temperature of a living organism's body because all organisms have water in their body. When heat is generated within the body, it is unable to disrupt internal temperature of the organism's body because the water does not get heated easily as a result of which the temperature of the body does not rise. On the other hand, the internal temperature of the body remains the same with slight decrease in the temperature outside because water does not radiate heat easily either. This is how high specific heat of water helps in maintaining a constant temperature in the body of organisms.

Answer:

"76 mmHg" is the partial pressure of oxygen on this new planet.

Explanation:

Atmospheric pressure on air on earth = 760 mmHg

On an unknown planet :

Oxygen makes up 10% of the atmosphere.

The mole fraction of oxygen gas can be written as [tex]x_1 = \frac{10}{100} = 0.1[/tex]

Carbon dioxide makes up 15% of the atmosphere.

The mole fraction of carbon dioxide gas can be written as [tex]x_2 = \frac{15}{100} = 0.15[/tex]

Nitrogen makes up the remaining 75% of the atmosphere.

The mole fraction of nitrogen gas can be written as [tex]x_3 = \frac{75}{100} =0.75[/tex]

Atmospheric pressure of air on unknown planet,p= 760 mmHg (given)

Partial pressure of gases can be calculated by the help of Dalton's law of partial pressure:

Partial pressure of oxygen gas :

                                       [tex]p_1 = p \times x_1[/tex]

                                           [tex]= 760mmHg \times 0.1\\=76mmHg[/tex]

Partial pressure of carbon dioxide gas :

                                      [tex]p_2 = p \times x_2[/tex]

                                          [tex]= 760mmHg \times 0.15\\= 114mmHg[/tex]

Partial pressure of nitrogen gas :

                                      [tex]p_3 = p \times x_3[/tex]

                                          [tex]= 760mmHg \times 0.75\\=570mmHg[/tex]

"76 mmHg" is the partial pressure of oxygen on this new planet.

Body-centered sex

MEN

Explanation:

Sex is defined in various way and portrays different meaning. Some define Sex as always a means of closeness for procreation, or  a way of showing love and feeling good(pleasure). To some, it is a sense of duty in fulfilling other partner's wish.  

Body-centered sex is a kind of sexual expression where the emphasis is placed on physical pleasure. it focus and draw attention of having sex for pleasure rather than emotion. An old adage once say and i quote "women fall in love with people; men fall in love with genitals." Hence,  Body-centered sex  is common in MEN

Answer:

1. Kreb's cycle breakdown the acetyl CoA into CO2 and H2O. The energy released is stored in the reducing powers (NADH and FADH2).

2. The electron transport chain oxidized the reducing powers into their oxidized forms. During this electron transport, the proton concentration gradient is produced across the inner mitochondrial membrane that drives ATP synthesis.

Explanation:

Kreb's cycle and electron transport chain (ETC) are the aerobic phases of cellular respiration. The carbon skeleton glucose enters Kreb's cycle in the form of acetyl CoA and is completely oxidized into CO2 and H2O. For one molecule of glucose, Kreb's cycle produces four molecules of CO2, 6 NADH, and 2 FADH2. In addition, two ATP are also formed by substrate-level phosphorylation.

The NADH and FADH2 enter ETC and are oxidized by giving their electrons to the molecular oxygen. Here, some of the energy of electrons is used to pump the protons from the matrix to intermembrane space. The resultant proton concentration gradient drives ATP synthesis. NADH produces the proton gradient enough to drive around 3 ATPs while FADH2 supports the formation of around 2 ATPs by oxidative phosphorylation.

Answer:

b) Systematics

Explanation:

Darwin presented the theory of evolution and explained that the process of evolution occured because of natural selection which further explains that offsprings are produced from organisms and these organisms are able to survive in their environment.

As systematics is the branch of biology, which basically deals with evolutionary relationships of the organisms .Thus the darwin theory of evolution will be considered in the field of systematics.

Hence the option B) Systematics is the right option.

Darwin's theory of evolution was largely based on concepts and data derived from the fields of demography, paleontology, and geology.

Charles Darwin, the founder of evolutionary biology, drew upon multiple academic disciplines to develop his groundbreaking theories. Particularly, he relied heavily upon concepts and data from demography, paleontology, and geology.

Demography provided him with insights into population dynamics, which formed the foundation of natural selection. Paleontology offered archaeological evidence of evolution over time through fossil records, proving the concept of 'descent with modification'. Geology made him understand that Earth's surface itself evolves, changing over very long timescales, which gave him a sense of the vast span of geological time during which evolution could occur.

Answer:

Dartos muscle.

Explanation:

The dartos muscle is responsible for the contraction and relaxation of the scrotum, adjusting the distance of the testicles from the body to maintain the ideal temperature for sperm production.

The muscle responsible for lowering and raising the testicles to regulate temperature for optimal sperm production is the dartos muscle. Sperm are produced in a temperature-regulated process that works best when the scrotal temperature is around 2 to 4°C cooler than the core body temperature. The dartos muscle, along with the cremaster muscle, contracts when cold to pull the testicles closer to the body, warming them, and relaxes when warm to allow the testicles to hang farther from the body, cooling them. This action is essential for maintaining the right temperature, which is on average 91 degrees Fahrenheit, as opposed to the normal core body temperature of most males, which averages at about 98 degrees.

Together, these muscles can elevate the testes in cold weather, moving them closer to the body and decreasing the surface area of the scrotum to retain heat. Alternatively, as the environmental temperature increases, the scrotum relaxes, moving the testes farther from the body core and increasing scrotal surface area, which promotes heat loss.

c. The harmless bacteria had been transformed.  

Explanation:

Fredrick Griffith carried out the first experiment that showed bacteria can get DNA by transformation in 1928.

He used two different strains of the bacteria Streptococcus pneumoniae a)type-III-S or smooth strain-Covered by a protective polysaccharide capsule hence lethal

b) type II-R or rough strain-Lacked the polysaccharide hence non-lethal

In his experiment he observed heat killed Type-III-S strain was not able to kill the mice. However, when its remains was added with rough strain then the blend was able to kill the mice.

When he collected blood  from the dead mice it had live strains of both smooth and rough type.

He came to a conclusion that non-lethal type II-R strain was transformed into lethal type II-S strain by a "transforming principle"  that was supposed to be the part of dead III-S strain bacteria.

The correct answer is: C. the harmless bacteria had been transformed.

Griffith called the process he observed transformation because the harmless bacteria used in his experiment had been transformed into a harmful form. In his famous experiment, Griffith worked with two types of bacteria: a harmless strain and a harmful strain.

He observed that when he injected mice with a mixture of heat-killed harmful bacteria and live harmless bacteria, the mice died. Upon further investigation, he found that the harmless bacteria had somehow taken up genetic material from the heat-killed bacteria and had been transformed into a harmful form.

Answer:

Biodiesel can be defined as an alternative fuel that is obtained from animal fats, vegetable oils, whether unused or burned. It is done by a chemical reaction called transesterification or another process called esterification. The final product is mixed with alcohol (usually methanol) and can be used in vehicles, either in certain diesel-biodiesel ratios or some engine modifications if it is desired to use alone.

Explanation:

Biodiesel is an important source of alternative energy, since it is a renewable fuel that can be obtained from a wide variety of vegetable and animal fats. It is less harmful to the environment by not generating the same levels of toxic gases that cause the greenhouse effect. On the other hand, glycerin, as a obtained by-product, can be used in applications such as detergents, food additives, cosmetic products, lubricants, etc. Characterizing animal fat may require a high degree of transesterification, producing a high quality biodiesel, which is currently used to recover the organic waste produced by the livestock industry.

According to law of segregation, the ratio of yellow peas to green peas at F2 should be 3:1.

                                             yellow                    green

Observed frequencies          5920                      2103

Expected frequency        [tex]\frac{3}{4}*8023[/tex] = 6017.25        [tex]\frac{1}{4} * 8023[/tex] = 2005.75

Using Chi square([tex]X^2[/tex]):

   [tex]X^2[/tex] yellow = [tex]\frac{(observed frequency - expected frequency)^2}{expected frequency}[/tex]

                        = [tex]\frac{(5920 - 6017.25)^2}{6017.25}[/tex]

                                   = 1.57

    [tex]X^2[/tex] green =  [tex]\frac{(2103 - 2005.75 )^2}{2005.75 }[/tex]

                        =   4.72

[tex]X^2[/tex] total = 1.57 + 4.72 = 6.29

Degree of freedom = 2 - 1 = 1

[tex]X^2[/tex] tabulated (α = 0.05) = 3.841

The calculated Chi square value is more than the tabulated Chi square value, hence, the conclusion is that the data are not consistent with law of segregation.

The process maintaining blood sugar level within a narrow range is homeostasis. It's primarily controlled by insulin, which reduces blood glucose by promoting its utilization, and glucagon, which increases blood glucose by stimulating glycogen breakdown during fasting or the postabsorptive state.

The bodily process that maintains blood sugar level within a fairly narrow range, despite uneven intake of sugar, is called homeostasis. This process is primarily controlled by two hormones, insulin and glucagon. Blood glucose levels tend to rise after a meal, and especially high-carbohydrate meals which would trigger the release of insulin from the beta cells of the pancreas. Insulin facilitates the uptake of glucose by the body cells and its utilization for energy production, thereby lowering blood glucose level.

On the other hand, during periods of fasting or the postabsorptive state, when glucose levels drop, glucagon is released from the alpha cells of the pancreas. Glucagon stimulates the breakdown of stored glycogen in the liver into glucose and its release into the blood, thus increasing blood glucose level. This process of regulation ensures that blood glucose is maintained within the optimal range for the body's function.

The typical American diet is high in sodium and low in fiber, vitamin D, and calcium, and lacks an emphasis on nutrient-dense foods. It is not high in fiber, contrary to one of the options provided.

Explanation:

The typical American diet is often criticized for its nutritional imbalances. Among the concerns is that the diet is generally high in sodium and low in essential nutrients such as dietary fiber, vitamin D, and calcium. Moreover, the diet tends to be heavy in calories from solid fats, added sugars, and refined grains, which can displace more nutrient-dense food options. In contrast, a healthier eating pattern would emphasize the consumption of vegetables, fruits, whole grains, and dairy products that are fortified or in their low-fat or fat-free forms to provide these essential nutrients while controlling calorie and sodium intake.

The correct answer to the question is that the typical American diet is not high in fiber; it is actually low in fiber. Over the decades, Americans have increased their consumption of foods high in sugar, which are low in fiber, thereby affecting overall health and nutrition adversely.

Covalent bonds are the ones that are formed by the sharing of electrons between the bonded atoms. Polysaccharides are the carbohydrates that have simple sugars bonded together by covalent bonds. Glycosidic linkage joins glucose residues of the starch together. Similarly, peptide bonds join the amino acids together to form proteins. Glycosidic bonds and peptide bonds are formed by sharing of electrons and are covalent bonds.

Monomers such as sugars and amino acids form polymers such as starch and proteins through covalent bonds. In specific terms, sugar monomers are joined via glycosidic bonds and amino acids are joined by peptide bonds - both are types of covalent bonds.

The type of bond that forms to join monomers (such as sugars and amino acids) into polymers (such as starch and proteins) is a covalent bond

These covalent bonds form when two atoms share one or more pairs of electrons. In the case of forming complex carbohydrates like starch - mono-saccharides (sugar monomers) are joined together via glycosidic bonds - a type of covalent bond.
