a. attractive.
b. career oriented.
c. good earners.
d. fond of children.
Answer:
The correct answer will be option-A
Explanation:
The practice of marriage is practised in every culture which is associated with the union of the boy and a girl to which they are committed to spending a life-long relationship.
The studies on the preferences shown by the woman who has to get married have to look for the boys who are career-oriented which could provide a good earning to feed them and their family and fond of children to establish a family which will help develop the stronger relationship between them.
The girls ignored the attractiveness feature of their spouses as in a long term relationship attractiveness does not matter because of the feeling of love and strong bond between them.
Thus, option-A is the correct answer.
A major side effect that stress can cause on the gastrointestinal system is __________. A. Diminished levels of gastrin
Answer:
elevated level of cortisol causing overeating
Explanation:
The stress affects the gastrointestinal system negatively in a number of ways and thus imbalance the normal functions. The low oxygen and flow of blood, cramps can be caused by stress. The stress response allows the signal to adrenal gland by nerves and hormone. The adrenal gland secretes cortisol and adrenaline.
The elevated level of cortisol allows the body to demand for food and fats. Thus, this increases the craving for eating food. So, a major side effect that stress can cause on the gastrointestinal system is elevated level of cortisol causing overeating.

What part of the spinal cord represents an increase in cell body mass for upper limb control?
a. cervical enlargement.
b. lumbar enlargement.
c. conus medullaris.
d. cauda equina.
Answer: a. cervical enlargement.
Explanation:
Cervical enlargement corresponds to the enlargement of the spinal cord. The spinal cord is the origin of the spinal nerves that contribute to an important task of supplying blood to the upper limbs.
The cervical enlargement results in an increase in the volume of the motor cells in the ventral part inside the grey matter. The motor neurons which are sited posteriorly supply to the upper limbs. Those which supply to the distal muscles are situated further posteriorly.
The a. cervical enlargement represents an increase in cell body mass for upper limb control.
Explanation:Cervical enlargement is a region in the spinal cord characterized by an increased concentration of cell bodies of neurons. This enlargement primarily spans the spinal cord segments C4 to T1 and is particularly prominent due to its role in controlling the upper limbs.
Neurons in this area are responsible for transmitting motor signals from the brain to the muscles of the arms and hands. The greater cell body mass in the cervical enlargement reflects the heightened neural complexity required for precise and coordinated control of the upper limbs, facilitating activities like fine motor skills, grasping, and manipulation.

Answer:
A, B, C, D, and E. (all of the above)
Final answer:
DNA contains genetic instructions for traits, encoded by genes. Half of an individual's DNA is inherited from each parent, influencing their unique combination of traits. Proteins, whose blueprints are found in DNA, significantly affect the characteristics of an organism.
Explanation:
DNA is fundamental to all life and contains the genetic instructions that determine traits. A specific section of DNA that codes for a particular trait is referred to as a gene. When it comes to inheritance, each parent contributes half of their DNA to their offspring, resulting in a combination of traits from both parents. Furthermore, DNA serves as a blueprint for proteins, which are crucial for numerous bodily functions. Lastly, due to variations in DNA among different organisms, proteins can vary greatly in their sequence of amino acids, which can lead to differences in traits across individuals.
Genes, Alleles, and Phenotypes
Each gene can exist in different versions, which are known as alleles. These alleles determine the genotype of an individual and, consequently, their phenotype, which encompasses all observable characteristics. An individual receives one allele from each parent, resulting in a unique combination that contributes to their individual traits.

Sudden change in environments that alters gene frequency of a population
Explanation:
The bottleneck effect is a genetic drift that happens when the size of a population is suddenly reduced for at least one generation, this can be triggered by a natural disaster. This sudden change leads to a decrease in genetic variation, as the population decreases the frequency of different alleles changes leading to a completely new population that may or may not be able to adapt. In the image, I added you can observe how the bottleneck effect works.
Considering this information we can conclude that the correct answer is "sudden change in environments that alters gene frequency of a population".
I hope you find this information useful and interesting! Good luck!
The correct answer is d) chance events that change allele frequency is bottleneck effect.
Genetic drift is a population's random variation in the frequency of a gene variant that already exists. The bottleneck and founder effects are the two types of genetic drift.
The bottleneck effect occurs when the population is significantly reduced as a result of earthquakes, floods, and other natural calamities.
The species that were resilient enough to survive the catastrophes make up the new population. The allele frequency and the this new population's allele frequency will not be similar.
Sudden change in environments that alters gene frequency of a population is natural selection.
Alleles transferred to the next generation in portions that differ from previous generation is genetic drift.
Transfer of alleles in and out of a population due to movement of fertile individuals is gene flow.

A conditional mutation is one that allows a mutant gene product to function normally under the ________ condition, but to function abnormally under the ________ condition. Such mutations are especially useful for the study of ________ mutations.
Answer:
A conditional mutation is one that allows a mutant gene product to function normally under the permissive condition, but to function abnormally under the restrictive condition. Such mutations are especially useful for the study of lethal mutations.
Explanation:
A conditional mutation can be described as a form of a lethal mutation as it's effects can be devastating. This type of mutation functions like a wild type mutation under the normal conditions. When the condition becomes restrictive, these kind of mutations start to show their effect on the phenotype of the organism. The conditional mutations can cause an organism to not be able to survive under certain conditions, which eventually leads to the death of the organism.
A conditional mutation functions normally under permissive conditions and abnormally under restrictive conditions, aiding in the study of lethal mutations. Dominant negative mutations are gain-of-function mutations that affect the normal gene product, used in studying genetic diseases.
Explanation:A conditional mutation is one that allows a mutant gene product to function normally under the permissive condition, but to function abnormally under the restrictive condition. Such mutations are especially useful for the study of lethal mutations.
Conditional mutations can be crucial in the study of essential genes that are required for survival. These mutations can allow an organism to grow normally under the permissive condition, which is typically at a lower temperature, while causing the phenotype associated with the mutation to be expressed under a restrictive condition, usually at a higher temperature. This technique enables researchers to switch the mutant phenotype on and off and study the gene's function.
A dominant negative mutation is a type of gain-of-function mutation where the mutated gene product interferes with the normal, wild-type gene product, often leading to a nonfunctional protein or altered cellular function. Such a mutation can be particularly informative when studying genetic disorders, syndromes, or genetic diseases like cancer, where mutations lead to uncontrolled cell growth and may arise from damaged DNA that fails to repair itself correctly.

What unit of light stimulates photoreceptor cells in the retina?
Answer:
Photons
Explanation:
The retina is a thin layer (membrane) in the eye that receives light through photoreceptor cells that convert this light into chemical and nervous signals transported to the brain's visual center.
The photoreceptors in the retina are known as rods and cones. Rods detect motion and sare responsible for black and white vision, they are present in the macula. Cones on the other and, are responsible for central and color vision. These photoreceptors absorb photons that trigger the membrane's potential of the cells.
I hope you find this information useful and interesting! Good luck!
A photon, which is a unit of light with properties of both a particle and a wave, stimulates the photoreceptor cells in the retina. These cells, rods, and cones, contain pigments that change in response to light, triggering visual perception.
Explanation:The unit of light that stimulates the photoreceptor cells in the retina is called a photon. A photon is a packet of energy that acts as both a particle and a wave. In the retina, photoreceptors such as rods and cones contain photosensitive pigments that undergo chemical changes when exposed to light. The two types of photoreceptor cells, rods and cones, perform different functions. Rods are responsible for vision in low-light conditions and do not mediate color vision, while cones are less sensitive but responsible for color vision and function well in brighter light. Each photoreceptor cell contains a pigment, and when exposed to light, the pigment undergoes a conformational change that ultimately leads to a change in the cell's membrane potential. This change in potential triggers a cascade of events that result in the perception of light.

Which of the following is NOT a function of the CSF?a.nourishment of the brainb.protection from blowsc.initiation of some nerve impulsesd.reduction of brain weight
Answer: c.initiation of some nerve impulses
Explanation:
Cerebrospinal fluid is a clear, colorless fluid that can be found in the brain and spinal cord. It is secreted by meninges and choroid plexus. It is absorbed by the arachnoid granulations.
The primary function of the CSF is to act as a cushion to the brain within the skull to serve as a shock absorber and prevents the injury from the blow. It also circulates the chemicals and nutrients filtered from the nerves and also removes the waste from the brain produced by the cerebral metabolism hence reduces the wastes from the brain.
The cerebrospinal fluid does not function in the initiation of the nerve impulses.
The cerebrospinal fluid (CSF) does not initiate nerve impulses. Its primary roles are to act as a cushion, reducing the weight of the brain, and to nourish the brain by transporting substances and removing waste, not to initiate nerve impulses.
Explanation:The function that is NOT attributed to the cerebrospinal fluid (CSF) among the options is the initiation of some nerve impulses. CSF primarily has two main roles in the Central Nervous System (CNS). First, it acts as a cushion for the brain and spinal cord, protecting these sensitive structures from shock or injury.

In C3 plants the conservation of water promotes _____.
a.photosynthesis
b.a shift to C4 photosynthesis
c.the opening of stomata
d.photorespiration
e.the light reactions
Answer:
The correct answer is d. photorespiration
Explanation:
In the C3 plant, the Rubisco enzyme is important that fix CO2 into organic molecule by binding with CO2. Rubisco can also bind to oxygen when the oxygen concentration increases in cells which leads to the loss of fixed CO2 and waste of energy which is called photorespiration.
So when stomata are open CO2 comes in and O2 goes out of the cell which maintains the high CO2 concentration in the cell but during hot days C3 plants close stomata to prevent water loss.
So closing of stomata decrease the intake of CO2 and increase the oxygen concentration inside the cell. So in increased temperature and high oxygen concentration, the rubisco enzymes bind to O2 and promote photorespiration.
In C3 plants, the conservation of water leads to photorespiration because in conditions where plants close their stomata to save water, CO2 cannot be utilized effectively, and plants begin to fix oxygen instead, initiating photorespiration.
Explanation:In C3 plants, the conservation of water promotes photorespiration. This is because during periods of drought or high temperatures, plants close their stomata to conserve water. However, when the stomata are closed to save water, CO2 levels within the leaf drop, and O2 levels rise. As a result, the enzyme Rubisco begins to fix O2 instead of CO2, initiating photorespiration instead of the normal photosynthesis process. Moreover, plants have developed adaptations to conserve water; for example, desert plants like cacti can fix CO2 at night when temperatures are lower, reducing water loss through transpiration. Overall, conserving water is critical in harsh environments to help the plants survive extreme conditions.
We think of termites as insects that eat wood. However, termites cannot digest the wood and rely on a variety of eukaryotic and prokaryotic gut microbes to digest cellulose. Without the microbes, the termites will still ingest wood but will starve. This, then, is an example of a(n); obligate mutualism. obligate antagonism. facultative mutualism. facultative antagonism. None of the answer options is correct.
Answer:
Obligate mutualism.
Explanation:
Obligate mutualism: It is defined as each organisms are obligated to each other, they rely on one another, means one species cannot survive without the other species. It may involve the interchange of resources, for example food, shelter, and nutrients or may interchange services like transportation, and protection.
Termites are mutualistic related to protozoa which lives inside the insects gut. Termite gets benefits from the bacterial symbiont ability which is present in the protozoa to digest the cellulose. The termites do not have this ability to do this, without the help of protozoa. They are not able to use their energy from the food which is wood, cellulose comes from wood it chews.
So, termites are mutualistic related to protozoans and showing obligate mutualism.
True or False: The arrows on a motion map must be connected to the dots on a motion map.
True. The arrows on a motion map must be connected to the dots on a motion map.
Explanation:
A motion map represents the movement of an object. The dots used in a motion map represent the position of an object and its displacement is represented by arrows. The dots come at the tail end of the arrows.
The direction of the arrows denotes the direction of displacement vector of the object. Thus reversing the direction of the object reverses the direction of arrows in a motion map. The length of the arrow represents the magnitude of the velocity vector which is the speed of the object.

b. Match tRNA anticodons and mRNA codons at the ribosome
c. Attach amino acids to tRNAs
d. Form the peptide bonds between amino acids at the ribosome
Answer:
Option c. Attach amino acids to tRNAs
Explanation:
The aminoacylation is the process of charging a tRNA molecule. The reaction is catalyzed by enzymes called AARSs (Aminoacyl-tRNA synthetases).
The reaction occurs during the process of translation. The first step is involved in using a ATP molecule amino acid activation, thus forming AARSs-aminoacyl adenylate complex. The amino acid (active) is transferred to tRNA in the second step of aminoacylation process. Thus, the function of aminoacyl-tRNA synthetases is to attach amino acids to tRNAs
Aminoacyl-tRNA synthetases link tRNA molecules to amino acids, enabling the correct amino acid to be added to the growing polypeptide chain. They first bind and hydrolyze ATP to form a high-energy bond between the amino acid and adenosine monophosphate (AMP), which is transferred to the tRNA. Charged tRNA molecules can then match their anticodons with the mRNA codons at the ribosome.
Explanation:Aminoacyl-tRNA synthetases are enzymes that link tRNA molecules to their corresponding amino acids, a process known as 'charging' the tRNA. Each of the 20 amino acids is linked to a specific synthetase. These enzymes first bind and hydrolyze ATP to form a high-energy bond between an amino acid and adenosine monophosphate (AMP), which is then transferred to the tRNA.
