A dominant gene is a type of gene which dominates in the inheritance pattern and masks the other one, on the other hand, a recessive gene is that which does not show its trait in inheritance pattern and hidden by the dominant one. A dominant gene is stronger gene while the recessive gene is a week gene. Dominant gene is always expressed in the upper case letters like A, F, V whereas recessive gene is always denoted by the lower case letters like a, f and v. dominant gene show in the inheritance when one of the two genes is dominant but in case of recessive gene both the genes of a trait should be recessive.
Traits you get from your parents. Inherited features evolve due to genetic material rearrangement and mutation. The parents transfer those traits (inherited) to their offspring. These aren't dying but passed on to the next generation. Example: earlobe attached or free, and curly hair.
An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence. Acquired traits are synonymous with acquired characteristics. They are not passed on to offspring through reproduction.

E. The inducer does not combine with repressor but functions as a chaperone molecule for the enzyme-substrate complex
The correct option is C.
The inducer combines with the substrate and blocks induction
Explanation:
Enzymes inducers are drugs or enzymes that Induces or bring out the activity of enzymes been expressed.
This drug increases the metabolic activity of an enzyme either it binded to the enzymes or in a away cause an increase gene code of an enzyme to be expressed.
When an inducer is added to a medium containing an organism with metabolic pathway controller by a repressor it will combine with the repressor and block induction because an enzyme repressor regulate enzyme activity in a negative way by reducing it's synthesis rate.

why carbohydrate digestion occurs first in mouth?
Answers
The digestion of starch carbohydrate is initiated in mouth due to the action of starch digesting enzyme ptyalin or salivary amylase present in saliva secreted by salivary glands. Enzymatic hydrolysis helps in the partial breakdown of starch (polysaccharide) into maltose and isomaltose (disaccharides) and small dextrins called 'limit' dextrins. Nearly 30% of the starch is hydrolysed in the oral cavity because of the shorter time the food is retained here

you decide to halve the time you spend in the shower each day and to turn off the water while you're brushing your teeth and washing your face at the sink. Evaluate the effect that these actions might have on two different aspects of the water cycle if every person in your neighborhood also performed them
Answers
Answer:
If every person in your neighborhood decided to cut the amount of water they use in half, that would have a tremendous positive effect on the water.
Explanation:
Reducing shower time and turning off water while brushing teeth conserves water, benefiting both water supply by preserving sources and reducing demand on treatment facilities.
By halving the time spent in the shower and turning off the water while brushing teeth and washing faces, individuals in the neighborhood can significantly reduce their water consumption. This would have a positive effect on both the supply and demand aspects of the water cycle. On the supply side, the reduced usage would decrease the strain on local water sources such as rivers, lakes, and underground aquifers. It would contribute to the conservation of these resources, promoting their sustainability and maintaining ecological balance.
On the demand side, the reduced water consumption would alleviate the pressure on wastewater treatment facilities, reducing energy requirements for water treatment and decreasing the discharge of treated water back into the environment. Overall, these actions would promote water conservation, help preserve natural water sources, and contribute to a more sustainable water cycle in the neighborhood.

Ductus arteriosus; right ventricle; aorta
Ductus arteriosus; aorta; right ventricle
Answers
A red blood cell in the umbilical vein of a fetus will flow next in the proper order as follows: Ductus venosus; vena cava; right atrium.The ductus venosus is a blood vessel that connects the umbilical vein to the inferior vena cava.
It allows oxygenated blood from the placenta to bypass the liver and enter the systemic circulation of the fetus. The red blood cell will pass through the ductus venosus, which acts as a shunt, directing the oxygenated blood towards the vena cava.
From the vena cava, the blood will enter the right atrium, which is one of the four chambers of the fetal heart. The right atrium receives deoxygenated blood from the body and the oxygenated blood from the umbilical vein.Finally, the blood will leave the right atrium and continue its circulation through the fetal heart, where it will be pumped to the lungs for oxygenation.
However, since the lungs are not fully functional in the womb, the blood is redirected through the foramen ovale and ductus arteriosus to bypass the pulmonary circulation.In summary, the correct order of flow for the red blood cell in the umbilical vein of a fetus is: Ductus venosus; vena cava; right atrium.

Is it a scientific theory or a scientific law that the characteristics of living things change over time?
Answers
Answer:
Scientific Theory
Explanation:
The statement "the characteristics of living things change over time" refers to the concept of biological evolution, which is widely accepted as a scientific theory in the field of biology. In scientific terms, a theory is a well-substantiated explanation of a natural phenomenon that is supported by extensive evidence, experimentation, and scientific consensus. The theory of evolution, proposed by Charles Darwin and further developed over time, provides a comprehensive explanation for the diversity and change in the characteristics of living organisms. It is supported by a vast body of evidence from various scientific disciplines, including genetics, paleontology, comparative anatomy, and molecular biology.
In contrast, scientific laws describe observable patterns or regularities in nature that are often expressed as mathematical equations or principles. Laws, such as Newton's laws of motion or the laws of thermodynamics, describe specific relationships or behaviors in the physical world.
Therefore, the statement about the characteristics of living things changing over time aligns with the theory of evolution, rather than being described by a scientific law.

Two locations have different water vapor Contant in the atmosphere which of this is likely to be recorded
Answers
Answer:
The water vapor content in the atmosphere is typically recorded using a measurement called relative humidity, which represents the amount of water vapor present in the air relative to the maximum amount the air could hold at a given temperature. Therefore, if two locations have different water vapor content in the atmosphere, it is likely that they would have different relative humidity readings.
For example, if one location has a higher water vapor content in the air, it would have a higher relative humidity measurement than a location with a lower water vapor content. Conversely, if one location has a lower water vapor content in the air, it would have a lower relative humidity measurement than a location with a higher water vapor content.
It is important to note that other factors can also influence relative humidity measurements, such as temperature and atmospheric pressure, so a direct comparison of relative humidity readings between two locations should take these factors into account.

Suppose in a strain of soybeans, high oil (H) content in the seeds is dominant to low oil content and four seeds (E) in a pod is dominant to two seeds in a pod. A farmer crosses two soybean plants, both with (High oil / four seeds: High oil / two seeds: Low oil / four seeds: Low oil / two seeds). What genotype were the parent plants?
Answers
The genotype of the parent plants in this cross is HhEe.
Based on the given information, we can determine the genotypes of the parent plants by examining the phenotypes of their offspring.
Let's denote the high oil content allele as H and the low oil content allele as h. Similarly, let's denote the four seeds allele as E and the two seeds allele as e.
The given parent plants have the following phenotypes:
- High oil / four seeds (unknown genotype)
- High oil / two seeds (unknown genotype)
- Low oil / four seeds (unknown genotype)
- Low oil / two seeds (unknown genotype)
From this information, we can deduce the possible genotypes of the parent plants by analyzing the inheritance patterns observed in their offspring.
If we cross two plants with the genotype HhEe (High oil / four seeds), we would expect the following ratios in their offspring:
- High oil / four seeds: 9/16
- High oil / two seeds: 3/16
- Low oil / four seeds: 3/16
- Low oil / two seeds: 1/16
Since the observed ratio matches the given phenotypes of the parent plants, it is likely that both parent plants have the genotype HhEe (High oil / four seeds).
Therefore, the genotype of the parent plants in this cross is HhEe.

Which statement correctly describes the bars on a bar graph representing the data?
The graph has five bars of equal height.
The bars range from tallest for very high concentration to shortest for very low concentration.
The bar for very low concentration is twice the height of the bar for medium concentration.
The bar for very high concentration is five times the height of the bar for very low concentration.
Answers
The table Paramecium Contractile Vacuole Contractions which correctly describes the bars on a bar graph representing the data is the bars range from tallest for very high concentration to shortest for very low concentration.
The data in the table records the number of contractions per minute of a paramecium's contractile vacuole in response to different salt concentrations in the surrounding environment.
A bar graph representing this data would have five bars, one for each level of salt concentration.
The bars would vary in height according to the number of contractions per minute, with the tallest bar representing the highest salt concentration and the shortest bar representing the lowest salt concentration.
Therefore, the correct statement describing the bars on the bar graph would be: "The bars range from tallest for very high concentration to shortest for very low concentration."
This statement accurately describes how the height of the bars would vary based on the data in the table.
The other statements do not accurately represent the data or the trends observed in the table.

Why does natural selection occur more when there is competition for resources?
Answers
Natural selection occurs more prominently when there is competition for resources because competition creates selective pressures that drive adaptations and favor certain traits over others.
In any given environment, resources necessary for survival and reproduction, such as food, water, and shelter, are limited. As a result, individuals within a population must compete with one another to obtain these resources.
Competition leads to differential survival and reproductive success among individuals.
Those individuals with advantageous traits or variations that enable them to more effectively acquire and utilize resources have a higher likelihood of survival and producing offspring.
These advantageous traits can be physical characteristics, physiological adaptations, or behavioral strategies that provide a competitive edge.
Through natural selection, individuals possessing beneficial traits are more likely to pass on their genes to the next generation, while individuals with less favorable traits are at a disadvantage.
Over time, this process results in the accumulation of beneficial traits within the population, enhancing their overall fitness and adaptation to the specific environment.
Therefore, competition for resources acts as a driving force for natural selection by selecting for traits that enhance an individual's ability to secure limited resources, survive, and reproduce successfully.
