Advances in science and technology have contributed significantly to the production of food in the world. Production capacity in agriculture has grown by 2.5 to 3 times over the past 50 years. This allowed, at a global level, that the increase in food production accompany the population increase.
An example of how technology has contributed to the increase in food production in the world is Transgenia. Through transgenic seeds, it was possible to plant crops that are more resistant to pests and to periods of drought, in addition, the transgenic crop has created crops with greater productivity. This has contributed greatly to the increase in food production.
Another example is the use of increasingly technological agricultural machinery, which can carry out agricultural work faster and more efficiently, reducing agricultural losses and contributing to increased production.

Aline is sitting in a physician's office and has just been told that a nurse will be coming in to measure her bmi. aline is not familiar with the term bmi and starts to panic. how should her mother reassure her about bmi tests?
Aline's mother can reassure her by explaining that BMI, or Body Mass Index, is just a simple way for the nurse to check whether Aline is at a healthy weight for her height.
The nurse will measure Aline's height and weight, and use these numbers to calculate her BMI. This is done by dividing Aline's weight in kilograms by the square of her height in meters:
[tex]BMI = \frac{\text{weight} (kg)}{\text{height}^2 (m^2)}[/tex].
The BMI helps to quickly and inexpensively screen if someone might be underweight, at a healthy weight, or overweight, but it doesn't measure body fat directly.
Aline's mom can also explain that the BMI test is very common and there is nothing to worry about. It's simply a tool that helps doctors and nurses make sure Aline is healthy.
what is the most important factor that determines the rate of diffusion in biological systems
The rate of diffusion in biological systems is most significantly determined by the concentration gradient, with other factors such as molecule mass, temperature, and solvent density also contributing.
The most important factor determining the rate of diffusion in biological systems is the extent of the concentration gradient. The concentration gradient refers to the difference in concentration of a substance across a space or membrane. A larger gradient results in a faster diffusion rate because more molecules will move from an area of high concentration to an area of low concentration. As the process nears equilibrium, where concentrations are equal, the rate of diffusion slows down significantly.
Additionally, other factors such as the mass of the diffusing molecules, temperature, and the solvent density can also influence the rate of diffusion. For instance, heavier molecules will generally diffuse more slowly compared to lighter ones. Higher temperatures typically increase molecular movement, thereby increasing the diffusion rate, while lower temperatures decrease it. Similarly, a denser solvent can slow down diffusion as the molecules find it harder to move through the medium.

What might happen if species A moved into a niche occupied by species B?
Both species would fight to the death.
One species would be forced to leave.
Both species would eventually starve.
The food resource would increase
Answer:
One species would be forced to leave.
Explanation:
If species A moved to the niche occupied by species B, the competition between the two species would be large enough for one species to be able to completely expel the other species from its niche.
The species that would remain in the niche would be the strongest and best adapted, while the species that proved to be weakest would be forced to leave the niche and look elsewhere.

Explain how hyperinflation might lead to a severe decline in total output.
Hyperinflation, often resulting from excessive money printing by governments, disrupts economic balance by triggering a surge in prices, deterring production and investment, and thus leading to a decline in total output. An historical example is post World War I Germany.
Explanation:Hyperinflation, which can be caused by national governments printing excessive amounts of money, often leads to a severe decline in total output. The reason is that with an increasing amount of money chasing the same or fewer goods and services, prices will rise significantly. This surge in prices can disrupt the balance of supply and demand, and deter production or investment, thereby resulting in a overall decrease in economic output. A historical example of hyperinflation is post World War I Germany, where the Weimar Republic resorted to printing money to pay its bills, leading to severe hyperinflation, economic crisis and eventually facilitating Adolf Hitler's rise to power.

What is the bone that forms the superior border of the bony pelvis
Final answer:
The ilium, as part of the hip bone, forms the superior border of the bony pelvis via the pelvic brim, which separates the greater pelvis from the lesser pelvis.
Explanation:
The bone that forms the superior border of the bony pelvis is the ilium, which is part of the hip bone or coxal bone. Specifically, the pelvic brim, also known as the pelvic inlet, includes the arcuate line of the ilium and forms the superior margin of the lesser pelvis, separating it from the greater pelvis.
The hip bone includes three regions: the ilium, ischium, and pubis. The ilium is the large, fan-like portion that creates the broad area of the upper hip bone and contributes to the pelvic brim. Together, the right and left hip bones, the sacrum, and the coccyx form the entire structure of the bony pelvis.

Determine whether a nail would be chiral or achiral.
A nail may be considered as an achiral object because it can be superimposed when it is faced in a mirror image where in it may look exactly the same rather than chiral when they are in a mirror image, it wouldn’t be superimposable.
Final answer:
A nail is considered achiral because it has a plane of symmetry, dividing it into two halves that are mirror images of each other, unlike chiral objects which cannot be superimposed onto their mirror images.
Explanation:
The question 'Determine whether a nail would be chiral or achiral.' touches on the concept of chirality, which is a property of objects where the mirror image cannot be superimposed on the original. Upon examining a nail, we notice it has a plane of symmetry that divides it into two mirror image halves. This means, regardless of any minor irregularities in real-life objects, the idealized version of a nail is symmetric and thus achiral, as it can be divided into two halves that are mirror images of each other.
In contrast, chiral objects do not possess such a plane of symmetry and cannot be superimposed onto their mirror images, like human hands. The importance of understanding chirality extends beyond simple objects into molecules, where chirality can significantly affect the properties and reactions of the molecules.
What are the elements called that have partially filled d sublevels?
If the d subshell has between 1 and 9 electrons, it is said to be partially filled if at least one d orbital is half-filled or vacant and at least one d orbital is full.
What elements called that have partially filled d sublevels?Any metal that produces one or more stable ions with partially filled d orbitals is said to be transitional. An element that has incomplete d subshells on its atoms or that can produce cations with incomplete d subshells is referred to as a transition element.
According to the aufbau principle, an atom's electrons must first occupy its lowest-energy atomic orbitals before moving on to its higher-energy counterparts.
Zn, Cd, and Hg have (n-1) “d(10)ns” electron configurations in their atoms, while their most stable simple ions, “M”(2+), have (n-1) “d (10)ns” electron configurations. So neither their atoms nor their simple ions have partially filled d-orbitals.
Therefore, it is called Transition elements are the elements called that have partially filled d sublevels.

A colorimeter is an instrument used for chemical analysis by comparing a liquid’s color with standard colors. In an experiment, a scientist used two calorimeters and noted the readings. The first colorimeter showed consistent readings that were five points lower than the actual reading. The second colorimeter provided readings that were the same as the actual reading. Which two statements are implications of these readings?
The first colorimeter is consistent but is not accurate; with an error of -5. It cannot be used to provide accurate reading.
U can conclude the second colorimeter to be accurate.
Answer:
Explanation:
The readings from the two colorimeters have the following implications:
1. The first colorimeter consistently showed readings that were five points lower than the actual reading. This suggests that there is a systematic error or calibration issue with this colorimeter. A systematic error is an error that occurs consistently and affects all measurements in the same way. In this case, the colorimeter consistently underestimates the color intensity by five points. To obtain accurate results, the scientist should adjust the readings from this colorimeter by adding five points to compensate for the systematic error.
2. The second colorimeter provided readings that were the same as the actual reading. This implies that the second colorimeter is properly calibrated and does not have any systematic errors. It provides accurate readings without any need for adjustments.
In summary, the first colorimeter consistently underestimates the color intensity by five points, while the second colorimeter provides accurate readings. To obtain accurate results, the scientist should adjust the readings from the first colorimeter by adding five points.
