Answer:To increase self-production of food and enhance its food security, Singapore has employed the use of technologies such as vertical farming and aquaponics in urban farming, nutrient recovery from food waste, biodegradable food packaging from durian rinds, natural preservatives, insect farming, microalgae and cultivated.
Many other herbicide resistant transgenic crops are currently under development (e.g., Roundup Ready alfalfa, Roundup Ready lettuce, Roundup Ready rice, Roundup Ready wheat and imidazolinone resistant wheat). ... Crops used for livestock and dairy feed will also be modified for improved utilization by animals.
If biofuels are produced from feedstocks that would have been used for food, then biofuels directly reduce potential food supplies. This reduction occurs even if feedstock price increases result in an expansion of supply because the expanded feedstock supply will typically reduce the supply of other food crops.
Increasing numbers of people often drive up demand for food, which typically results in additional use of arable land and water. This is especially true in the absence of adequate food production technology and integrated programs that simultaneously address community needs for food and reproductive health.

How does the flu vaccine, an injection usually composed of a small amount of live but not harmlul
viral cells, prevent a person from getting sick with the flu virus?
It stimulates the host cell to produce antiviral toxins, which are released
continually into the respiratory tract, to destroy the viral cells even before they
are recognized by white blood cells.
А
B
It prevents the flu virus from converting host cells into pathogenic bacterial cells,
which are the source of a person's symptoms, as it is the bacterial cells that
damage the respiratory tract.
Ос
It initiates the production of memory cells specific for that year's predicted flu
virus. When the flu virus is inhaled, it is recognized quickly by memory cells and
destroyed.
D
It gives a person a mild case of the flu all year long. Since the person already
has an active form of the flu virus, it is impossible to infect that person again
with another flu virus.
Answer:
It stimulates the host cell to produce antiviral toxins, which are released continually into respiratory tract, to destroy the viral cells before they are recognized by the white blood cells.

In the photograph below, two fish are displaying a behavior commonly observed among pairs of rabbitfish. While one has its head down feeding on coral, the other remains upright, alert for predators. This behavior continues to be present in the rabbitfish population because A) this behavior was learned by observing other fish species B) both fish could not fit into the small spaces in the coral C) this behavior increases their chance of survival D) the fish species needed to become alert to survive
D. because if they're not careful they become extinct by predators, then they have to be careful to survive by staying alert.

How would an increase in nest sites affect a population of pigeons?
The population would decrease.
The population would increase.
The population would remain almost the same.
The population would be reduced the next year.
Answer:
B. The population would increase.
Explanation:
The population would increase because the more spaces for the pigeons to breed and raise their offsprings.
The population will increase if there is an increase in nest sites which affect the population of pigeons. So, the correct option is B.
What is Population?The population is the overall amount of people residing in a certain area. Estimating the population enables us to determine how many beings there are and how best to respond. For instance, we can determine how many resources a city will require if we know the specific population of that city.
A population is the entire set of people in a group, whether that group is a country or a collection of people who share a certain trait. A population is the group of individuals that are selected when a statistical sample is taken in statistics. If there is an increase in nesting locations, which has an impact on pigeon population, the population will grow.
Therefore, the correct option is B.

Animals that have a complete
tube-like gut with two openings
Answer:
All mammals, like dogs, cats, and humans; reptiles, amphibians, fish, birds, and even insects.
Explanation:
All mammals, like dogs, cats, and humans; reptiles, amphibians, fish, birds, and even insects are the animals that have a complete tube-like gut with two openings. A system having a tube with two openings i.e. mouth and an anus is called tubular system. In this tubular system, the animals eat with one opening and the other opening is used for excretion of waste and nitrogenous materials from the body so that's why most of the animals have two openings.

1. What makes the problem of famine in Third World countries so difficult to solve? 2. What happens to the overproduced food in wealthy countries?
3. If genetic engineering fails, what other solutions can there be to global starvation?
4. Why may genetically engineered foods be considered dangerous to humans?
5. Do you make a point of reading labels on food packages? Does it make sense?
Answer:
1) Markets need to be better integrated on a local, provincial, and national level to avoid an accumulation of surpluses, which depresses prices and leads to a poverty trap for farmers.
2)Food too expensive to be purchased will rot in the warehouse. Food too unprofitable to harvest will be lost in the field. Meal servings that are twice what a person can eat will be partially discarded. A perfectly edible apple with harmless spots or a misshapen carrot might be tossed in a landfill.
3)The world's food supply is abundant, not scarce. The world's production of grain and other foods is sufficient to provide at least 4.3 pounds of food per person, per day. The real reason for hunger in the world is poverty, which often strikes women--the nutritional gatekeepers in many families--the hardest. Economists argue that resolving hunger requires political solutions and not just agro-technical solutions. According to them, instead of looking at biotechnology as a yet unproven and non-existent breakthrough, decision makers should look at the full body of research that shows that solutions to eliminate hunger are not technological in nature, but rooted in basic socio-economic realities.
4)genetic-engineering process could cause “unnatural” changes in a plant's own naturally occurring proteins or metabolic pathways and result in the unexpected production of toxins or allergens in food

7. The diagrams show stages in the passage of water through a plant,
The circles are the starting points for arrows to show the direction in which the water moves.
Which circle must have an arrow pointing downwards only?
From the understanding of how water moves through plants, the only circle that can have a downward pointing arrow only is A.
Water moves through a plant in the following direction:
Soil ----> root -----> stem ----> leaves
Once water gets into the root from the soil, a conducting tissue known as xylem conducts the water upward through the stem of the plant branching off into the leaves through the petiole. from the petiole, water is then conducted to the mesophyll cells.
Circle D represents the root, so the arrow must be upward.
Circle C represents the stem, the arrow continues upward towards the leaves
Circle A and B represent the leaf. The movement of water within the leaf might requires that it is from circle A to circle B. Hence, the only circle that must have an arrow pointing downward only can only be A.

In a batch culture, bacterial cultures typically exhibit four different phases of growth. In which phase are the cells rapidly synthesizing proteins, but cell numbers are not changing
Answer:
Lag phase
Explanation:
The lag phase is the first phase of bacteria growth and it is refer to period when bacteria is first introduced to the culture and the time it started increasing. The lag phase is the phase bacteria adapt to growth conditions and start surviving in the environment. It is the time bacteria start growing and cannot divide. In this phase , RNA and enzymes are synthesized.
