passive immunity - naturally acquired
passive immunity - artificially acquired
Answer:
The correct answer is - passive immunity - artificially acquired.
Explanation:
Passive immunity is the immunity that involves giving or acquiring antibodies from other sources instead of developing them on one's own. This type of immunity can be natural and artificial. Mother breastfeed the babies, is the natural passive immunity example as milk also contain antibodies required for immunity of babies.
Artificial passive immunity is the immunity that comes from injecting the antibodies created in different animals or persons which called antiserum or vaccines such as snake antivenom.

Carbon dioxide is a naturally occurring gas that is vital to plant and animal life, yet carbon dioxide emissions from burning of fossil fuels are expected to result in significant climate change within 100 years. Should carbon dioxide be considered to be a pollutant? Support your position by providing reasons why or why not.
Answer:
Yes, it should be considered a pollutant
Find the reason below
Explanation:
A pollutant is any substance that poses threat or causes harm to the sustainability of the environment. As rightly stated in this question, carbon dioxide (CO2) is a naturally occuring gaseous constituent of our atmosphere. It is vital to both animal and plant life as it is utilized by plants to synthesize their food (glucose), which is the starting point for the flow of energy.
Although CO2 plays a major role in sustaining life, it is also a major cause of GLOBAL WARMING. Carbon dioxide is considered the most important greenhouse gas as it has the ability to trap and emit heat, contributing to the global rise in atmospheric temperature. This causes a lot of harm and environmental disturbance, hence, CO2 despite its beneficial purpose, should be considered a POLLUTANT.

would it be better to mine in a wilderness area than a developed area?
Answer:
Yes.
Explanation:
Mining in a area of wilderness can provide great succes as long as you know the area well and know some things about where to mine and not.
Answer: Yes, it is better to mine in a wilderness area than a developed area.
Explanation: Mining is carried out to gather raw materials that serve as the foundation for any country's or region's growth. It is more likely to occur in a wilderness area than in a developed area because mining usually has a negative impact on the environment.
The ores recovered by mining, such as oil, coal, metals, and others, cannot be obtained from any developed location, and the mining process destroys settlements in developed areas.

The disorder known as cystic fibrosis (CF) is inherited in a recessive autosomal manner. In populations of Northern European descent, the frequency of people with CF is about 1 in 2,500. Assuming Hardy-Weinberg equilibrium for this disorder, answer the following: A. Assuming Hardy-Weinberg equilibrium, what percentage of people in the population would be expected to be heterozygous carriers
Answer:
The correct answer is -
A. 3.9% people in the population would be expected to be heterozygous carriers
Explanation:
The genotype frequency for the CF affected is 1/2,500,
= 1/2500
= 0.004. This is equal to q^2
here q = frequency of recessive alleles combination or CF people. (H-W equation => p^2+q^2+2pq=1)
The allele frequency is the square root of q^2 value, which equals 0.02. The frequency of the dominant allele or p would be
1 - 0.02 = 0.98 (p+q = 1)
The frequency for the CF combinantion =0.004
the dominant or unaffected people genotype
= (098)^2
= 0.96;
and for the heterozygote, it is
= 2pq
=2(0.98)(0.02)
= 0.039 or 3.9%

→X x K i m 0 2 x XDescribe how climate change will impact the human population.
*5 sentences or more*
Answer:
the answer is in the picture.
Answer: Climate change will likely increase the frequency and strength of extreme events (such as floods, droughts, and storms) that threaten human health and safety. Climate changes may expose more people to diseases. Some groups of people (e.g., the very young and the very old) are especially vulnerable to health impacts. First, older people are physically more vulnerable to extreme heat, so population aging could exacerbate increases in heat-stress mortality brought on by climate change. Higher temperatures also exacerbate outdoor air pollution such as ozone, which also disproportionately affects older people. Human health is vulnerable to climate change. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats. Climate affects population distribution both directly as well as indirectly through its effects on soil, vegetation and agriculture that have direct bearings on the pattern of population distribution. ... This explains a high density in the tropics, which are otherwise marked with extremes of climatic conditions.

Which component of milk causes caramelization when heated?
Answer:
i think its carbohydrates
Explanation:
As the carbohydrates are heated, the molecules break down and reform into compounds with a characteristic brown colour and flavour.
hope this helps
The component of milk that causes caramelization when heated is lactose, as it is a disaccharide sugar that is present inside milk and consists of monosaccharides such as galactose and lactoses.
During the caramelization process in milk, heat causes the lactose molecules to undergo thermal decomposition due to the heat, resulting in the formation of various compounds, such as caramelan, caramelene, and carameline, etc. These compounds are the major factors for browning and flavor development of milk when it is heated. At a high temperature, the caramelization process is done.

Self-portraits can help you learn about positioning people in a photograph.
True
False
A camera's self-timer takes a picture after a certain amount of time has passed.
True
False
1.) True
The reason this is true is because adjusting the camera allows you to get an understanding of how someone else should look or how they would likely look best when photographed. It also gives an understanding of how a camera should be aimed to get the best result.
2.) True
While many cameras have this feature, most are configured to only use this feature when the photographer selects it. This feature allows the photographer to adjust the camera in case they feel something isn't quite right with it, and it also allows them to get into the picture themselves if they feel they want to.
Hope this helps you, and have fun with whatever it is you are doing with your camera.

Explanation:
A possible consequence of staphylococcal infections is glomerulonephritis. Glomerulonephritis affects the filtration membrane by causing the basement membrane underlying the glomerular endothelium to lose its negative charge. The negative charge on the basement membrane is what prevents plasma proteins from entering the filtrate. Thus, with this condition, proteins can enter the urine (proteinuria). What effect will this have on the glomerular filtration rate
Answer:
Proteinuria is a general characteristic in different types of kidney and renal diseases where different types of proteins come in the filtrate. This causes a diminishing in the glomerular filtration rate due to the reason that proteins in the filtrate cause aggravation and scarring.
Explanation:
The value of Glomerular Filtration Rate or GFR is given as
[tex]GFR=K_f(P_c-P_b)-\pi_c[/tex]
Here
K_f is the Permeability constant of glomerular capillariesP_c is the hydrostatic pressure of the glomerular capillaryP_b is the hydrostatic pressure of the Bowman's spaceπ_c is the oncotic pressure of the glomerular capillaryAs the proteins start to occur in the filtrate, they reduce the [tex]P_c[/tex] and increase the value of [tex]P_b[/tex]. This leads to a reduced difference [tex]P_c-P_b[/tex], which leads to reduced GFR as they are directly proportional.
Severe flooding in an area caused a population of minnows to become split into two separate ponds. Prior to the separation, the male minnows all had a moderate number of spots. Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female minnows in this pond preferred to mate with males that had the most spots. After many generations, the two minnow populations evolved into different species and could no longer interbreed.
Answer:
Geographic isolation
Explanation:
Geographic isolation occurs when a population is split by geographic factors, such as the flood mentioned. They can become separate species over time and will no longer be able to produce viable offspring. Hope it helps :)

Dinosaurs evolved over millions of years and became well-suited to their
environment. Unfortunately, dinosaurs did not have the ability to adapt to the
climatic change that occurred sixty-five million years ago due to the asteroid
collision. Which statement best describes why the dinosaurs were unable to survive
this event?
Answer:
Dinosaurs did not have the ability to adapt to the climatic change that occurred sixty-five million years ago due to the asteroid collision.
Explanation:
The rapid extinction of dinosaurs is believed by many scientists to have been caused by the very powerful meteorite impact on the northern Yucatan Peninsula about 65.5 million years ago, which created the Chicxulub crater. After that event, no dinosaurs have been found other than early birds, suggesting that all died out during or just after this short period.
The event enabled mammals to evolve and fill many of the ecological niches that were liberated since the disappearance of the dinosaurs. Even about a third of all known mammals disappeared in this mass extinction.
