Answer:

The correct answer is "natural selection in Staphylococcus aureus populations".

Explanation:

Natural selection is a process at which populations of organisms develop advantageous traits under the premise of survival of the fittest. In this case, the continuous exposure to penicillin and other antibiotics since 1940s have a natural selection effect in Staphylococcus aureus populations, allowing an increase in antibiotic-resistant alleles in the bacteria, which acts as an advantageous trait for them. Antibiotic resistance is a serious medical concern that has been addressed by a culture of responsible use of antibiotics and development of novel treatments for infections.

Answer: b) to understand the interaction between the human user and the mechanics of equipment or devices

Explanation:

To understand the interaction between the human user and the mechanics of equipment or devices is NOT a goal of biomechanics.

Biomechanics by definition in dictionaries is the branch of biophysics that deals with the mechanics of the human or animal body; especially concerned with muscles and the skeleton.To study  the mechanics of a living body it is necessary to understand  the forces exerted by muscles and gravity on the skeletal structure, as well as the mechanics of a part or function of a living body, for example  the heart or of locomotion.

The answer is d) to understand the relationship between mechanical laws and movement techniques of specific movements to improve the outcome or effectiveness of movements.

The correct answer is d) to understand the relationship between mechanical laws and movement techniques of specific movements to improve the outcome or effectiveness of movements. The field of biomechanics aims to understand the mechanical principles behind human movement and the structure and function of the human body. It involves analyzing the physics of motion, the interaction between humans and equipment, and identifying solutions to improve performance and well-being. However, it does not focus solely on the relationship between mechanical laws and movement techniques of specific movements.

Answer:

The correct answer is amino acids.

Explanation:

When food is consumed it contains nutrients in the form of polymers like starch, proteins, lipids and nucleic acids(DNA). These polymers can not be absorbed directly by the body because of their complexity and larger structures.  

Therefore they must be broken down into smaller forms by digestive enzymes. After digestion, they are broken into smaller and simpler forms like amino acids, glucose, fatty acids, etc. Then these simpler forms are absorbed through the digestive tract in the body.  

So as amino acid is the simpler form of proteins so it can be absorbed by cells lining the digestive tract.

The use of Punnett square in Mendel’s law helps in predicting the phenotype and genotypes from genetic crosses of offspring.

Explanation:

The study of trait inheritance in pea plants is performed by Gregor Mendel. He developed a model of pair of genes that specify the traits. There are different alleles of genes in a population of living organisms. His law of segregation states that one of the two copies of gene that is present in a specific organism gets distributed to gametes produced by it.

The F2 generation of gene is represented by Punnett model and by counting the squares of this model the genotype and the phenotype ratio can be predicted.

Answer:

Control of both RNA splicing and chromatin remodeling control of RNA splicing.

Explanation:

RNA is present as genetic material but in case of some viruses only. RNA contains the nitrogenous base ( adenine, guanine, uracil and cytosine), oxyribose sugar and phosphate group.

The bacteria do not have well developed nucleus so no chromatin remodification occurs in case of bacteria. Bacteria is devoid of introns and contains only exons in its RNA structure. The splicing process is not required in case of bacteria.

Thus, the correct answer is option (4).

Explanation:

Answer: There will be no genetic variability in the gametes produced.

Explanation:

Meiosis is a type of cell division to form gametes, which are haploid cells and genetically distinct from the cell that gave them their origin.

During the interphases of meiosis I, each chromosome is duplicated. And after that, during prophase I, the phenomenon of crossing over occurs which is the exchange of genetic material between male and female chromosomes.

In metaphase I, the homologous pairs of chromosomes align on the equatorial plate; and during anaphase I the spindle fibers pull them away and toward each pole of the cell. At the end, in telophase I, the chromosomes are enclosed in nuclei and the nuclear membrane is formed.

If the maternal chromosomes are aligned on one side and the paternal ones on the other, without crossing over having occurred, then the new formed gametes will have the same maternal or paternal genetic material according to which chromosomes they receive. This means that there will be no genetic variability in the gametes produced.

Explanation:

A must be two amino acids longer -each codon encodes one amino acid.

Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.

Further Explanation:

The nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and protein synthesis.

Basic makeup: C, H, O, P... life on Earth is Carbon based nucleotides contain 5-carbon sugars, and  nitrogen; the bases may contain single to double bond rings

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes.  Codons are three nucleotide bases encoding an amino acid or signal at the beginning or end of protein synthesis.

RNA codons determine certain amino acids so the order in which the bases occur within in the codon sequence designates which amino acid is to be made bus with the four RNA nucleotides (Adenine, Cysteine and Uracil) Up to 64 codons (with 3 as stop codons) determine amino acid synthesis. The stop codons ( UAG UGA UAA) terminate amino acid/ protein synthesis while the start codon AUG begins protein synthesis.

A

Explanation:

Golgi apparatus is an organelle in eukaryotic cells that stores and modifies (might include addition of sugar groups) proteins and lipids for certain functions and prepare them for transport to other parts of the cell.

In the Endoplasmic reticulum, proteins fold into into their correct shape. Some of them are transported to the Golgi apparatus in membrane vesicles. Some proteins need to do their jobs in the Golgi (they are said to be Golgi-resident). They are transported from the golgi appratus to their final destinations through a secretory pathway. It involves sorting proteins into different kinds of transport vesicles, which emanate from the trans Golgi network and deliver their contents to the appropriate cellular locations.

Proteins that are membrane embedded are conveyed to the plasma membrane (integral membrane proteins) by constitutive secretion. Proteins can divert from constitutive secretion pathway and be targeted towards other destinations such as lysosomes (as lysosomal proteins) and regulated secretion from cells (to the cell exterior).

Proteins destined for the lysosome, plasma membrane, and secretion are sorted in the trans-Golgi network. This part of the Golgi apparatus acts as a crossroads for protein traffic, sending proteins to their correct destinations.

The answer to the question is Proteins destined for locations such as the lysosome, plasma membrane, and for secretion are sorted in the trans-Golgi network. The trans-Golgi network (TGN) is the part of the Golgi apparatus involved in sorting proteins to their correct destinations. It effectively acts as a crossroads for protein traffic, sending proteins to the right places based on specific sorting signals contained within the proteins themselves.

For example, proteins that will end up in the lysosome (which serves as the cell's waste disposal and recycling center) have a specific marker that the TGN recognizes. The TGN then sends these proteins to the lysosome. Likewise, proteins destined for the plasma membrane (which controls what enters and leaves the cell) and those destined for secretion (sent out of the cell to perform various functions) are recognized by the TGN and sent to their respective locations.

Answer:

Towards the right

Explanation:

The Coriolis force is usually defined as the force that acts on the global wind and ocean currents and allows them to move in a clockwise and anticlockwise manner, in the northern and southern hemispheres respectively. This force occurs due to the rotation of the earth.

The strength of this Coriolis force gradually increases with the increasing latitudes and also increases with the gradually decreasing speed of the earth's rotation. So, the value of this force is observed to be highest at the poles and is absent at the equator.  

Thus, in the northern hemisphere, the Coriolis force deflects the wind to the right side.

Answer:

The correct answer is The cells do not have proper receptor.

Explanation:

During paracrine signaling a signaling molecules are generated from one cell.The generated signaling molecule then binds to the receptor of neighboring cell to carry specific signal from donor cell to the acceptor cell.

  But the signaling molecules will not bind to the cell that is producing it because that producing cell do not contain proper receptor to bind that signaling molecule.

 The binding of signaling molecule to the receptor of its producing cell occur during autocrine signaling.

Final answer:

The most likely reason paracrine signaling does not activate the signaling cell is that the cell lacks suitable receptors for that signal, ensuring signals are directed to and activate neighboring cells instead.

Explanation:

The most likely reason that paracrine signaling does not activate the cell producing the signaling molecule is that the cell does not have the proper receptor for that signal. Paracrine signals are those that are released by cells and act on adjacent nearby cells. For the signaling to be effective, the receiving cells must have appropriate receptors specific to the signaling molecules. Since the cell producing the signal is releasing it for neighbouring cells, it typically lacks receptors to respond to that specific signal or the receptors that are present don't bind to the cell's own signaling molecules as effectively. This specialization of cells ensures that signals are directed and that cells can coordinate behaviors in a localized manner without being activated by the signals they produce themselves.

In contrast, autocrine signaling involves cells that have receptors for the signals they produce, and thus, they can indeed activate themselves. However, in paracrine signaling, the signals move through the extracellular matrix and elicit quick responses. To ensure the response is localized, these signaling molecules are quickly degraded or removed, thereby preventing their activation of the producing cell and establishing a concentration gradient for efficient diffusion when released again.

Answer & explanation:

Channel proteins are specific types of proteins that have aqueous channels along their molecules and are associated with substance transport.

These proteins act passively because they are part of the passive transport of cells, since there is no energy expenditure to internalize the substances, they enter the protein channels requiring a favorable concentration gradient for this process to occur.

Channel proteins may have gated or non-gated channels.

Answer:

b. intracellular fluid moves to the outside of cells

Explanation:

The presence of an excess of sodium ions in the extracellular fluid would make it hypertonic with respect to the intracellular fluid. The concentration gradient would drive the intracellular fluid towards the outside of the cell to balance the concentration of the fluids on either side. The passive movement of fluids occurs across the cells and is driven by the concentration gradient only. The biological membranes are permeable for fluid movement such as the movement of water across it.

Final answer:

Furosemide is a loop diuretic that inhibits Na+ and Cl- reabsorption in the nephron loop, leading to a decrease in water reabsorption and thus a larger amount of urine produced.

Explanation:

The drug in question, furosemide, is a loop diuretic that targets the nephron, specifically the ascending limb of the loop of Henle, which is crucial for the reabsorption of sodium (Na+) and chloride (Cl-) ions. This reabsorption is important for the concentration of urine, as it allows for water to be reabsorbed in subsequent parts of the nephron. When furosemide inhibits this process, it prevents Na+ and Cl- reabsorption, which in turn leads to less water being reabsorbed. This results in more water remaining in the urinary system, thus increasing the volume of urine produced. Therefore, the predicted effect of furosemide on the quantity of urine produced is that there will be a large amount of urine produced.

Answer:

1. XaY,BB and XaY,Bb

2. Father: XaY,Bb

Mother: XAXa,bb

Son: XaY,Bb

Daughter: XaXa,bb

Explanation:

1. Gender: Male --> XY, Color-blind male: XaY, Brown-eyed: BB or Bb. Combine the aforementioned, the gametes can be formed with respect to these genes by a heterozygous, brown-eyed, color-blind male are: XaY,BB and XaY,Bb

2.  MOTHER: Blue-eyed female with normal vision : XAXA,bb or XAXa,bb

SON: brown-eyed male, color-blind:  XaY,BB or XaY,Bb

DAUGHTER: blue- eyed female, color-blind: XaXa,bb

From the genotype of the son, we can assume that the father must has brown eyes: BB or Bb. Besides, the daughter has blue eyes. Thus, the daughter received the autosomal gene "b" from her parents. At the conclusion, the father eyes color genes is Bb. We can assume that Father genre can be XAY,Bb or XaY,Bb.

Both of son and daughter are color-blind. Thus, Mother genotypes should have Xa. Finally, Mother Genotypes is: XAXa,bb.

Because both children are color-blind, the father genre is: XaY,Bb, brown eyes and color-blind male

Mother (XAXa,bb) × Father (XaY,Bb)

Final answer:

A heterozygous, brown-eyed, color-blind male can produce gametes with two possible combinations: XaB and XaB. If a blue-eyed mother with normal vision has a brown-eyed, color-blind son and a blue-eyed, color-blind daughter, the mother must be a carrier for color blindness, and the son and daughter inherited the recessive colorblind allele from their parents.

Explanation:

In humans, red-green color blindness is determined by an X-linked recessive allele (a), whereas eye color is determined by an autosomal gene. A heterozygous, brown-eyed, color-blind male can produce gametes with two possible combinations: XaB and XaB. The XaB gamete is color-blind and has brown eye color, while the XaB gamete is color-blind and has blue eye color.

If a blue-eyed mother with normal vision has a brown-eyed, color-blind son and a blue-eyed, color-blind daughter, the genotypes of both parents and children can be deduced. The mother must be a carrier for color blindness, with the genotype XaX. The son inherited the X chromosome with the recessive colorblind allele (Xa) from the mother, and the daughter inherited the X chromosome with the recessive colorblind allele (Xa) from the father.

Final answer:

Rocky Mountain juniper and one-seeded juniper are kept separate by gametic isolation, preventing their pollen and ovules from successfully interacting and fertilizing.

Explanation:

The Rocky Mountain juniper (Juniperus scopulorum) and one-seeded juniper (J. monosperma) are kept separate by a process known as gametic isolation. This type of reproductive isolation occurs when pollen grains from one species (which contain the sperm cells) are not able to germinate and create pollen tubes on the female ovules (which contain the egg cells) of another species. Since these two juniper species have pollen and ovules that do not interact successfully to allow fertilization, they are unable to produce viable offspring together. This mechanism prevents the gene pools of the two species from mixing, thereby maintaining them as separate species despite their overlapping ranges.

Answer:

Proventriculum and gizzard

Explanation:

In birds, the stomach is divided into two compartments: the proventriculum and the gizzard. These structures are less distinct in carnivorous species, and well-prominent in grain and seed-feeding species.

The proventriculum is a structure located between the lower esophagus and the gizzard. It is covered by a glanular mucous layer with secretory function and is therefore responsible for the secretion of enzymes and hydrochloric acid for digestion.

The gizzard is considered a muscular stomach, responsible for crushing and macerating food (as in chewing). It has a highly developed and strong musculature, resistant to the action of hydrochloric acid.

Answer:

B) remove contaminating microorganisms and initiate repair of damaged tissues.

Explanation:

Schematically we can divide the inflammation into five stages:

1- Release of mediators. They are molecules, most of them, of elementary structure that are released or

synthesized by the mast cell under the action of certain stimuli.

2- Effect of mediators. Once released, these molecules produce vascular alterations and effects

Chemotactics that favor the arrival of molecules and immune cells to the inflammatory focus.

3- Arrival of molecules and immune cells to the inflammatory focus. They come mostly from the blood, but

also from the areas surrounding the focus.

4- Regulation of the inflammatory process. Like most of the immune responses, the inflammatory phenomenon

It also integrates a series of inhibitory mechanisms aimed at finalizing or balancing the process.

5- Repair. Phase consisting of phenomena that will determine the total or partial repair of tissues

damaged by the aggressor or by the inflammatory response itself.
