How could biotechnology lead to a decrease in the use of pesticides?
Plants can be genetically engineered through the use of biotechnology to be less susceptible to insects. This trait will make pesticide use less necessary.
This is the sample answer on edge.
This method combines the genetic productivity enhancement of plants with the management of their hazardous organisms.
How is biotechnology used?Typically, agricultural biotechnology is utilized to boost plant production productivity to reduce the use of pesticides.
In agriculture by applying biotechnology, pest management and the use of pesticides will be reduced for modified plants.
The emergence of insect-resistant plants will be accelerated by technological advancements, and with an improved grasp of biotechnological processes, the acceptance of biotechnology goods might grow.
Therefore to reduce paste management and make crop resisitance for paste biotechnology is used.

Bison in Yellowstone National Park have a food-limited carrying capacity that determines how their population grows. If the population grows too large, some bison will either starve or migrate to search for more food. The park is able to support a maximum population of 4,500 bison. Park conservation officials must watch the population and prevent the bison from overpopulating, since they would migrate to nearby farms, causing agricultural damage and creating hazards to drivers. The bison begin to migrate when the population reaches 4,000 because of competition for food. If the current population size of bison is 3,652 and the maximum growth rate of the population is 0.28, calculate the population size after one year and determine whether the park will need to take measures to control the population.
A. The population will be 3,845 after a year. The bison will not pose a problem until the following year, and no conservation action will need to take place.
B. The population will be 4,675 after a year. Some bison will need to be removed to prevent migration, since they will surpass the resource availability.
C. The population will be 1,023 after a year, since the growth rate is too low. Conservation efforts will need to focus on increasing the bison population.
D. The population will be 4,500 after a year. The bison cannot exceed the carrying capacity, so they will stop reproducing. Some bison will need to be removed.
Answer:
A. The population will be 3,845 after a year. The bison will not pose a problem until the following year, and no conservation action will need to take place.
Explanation:
The exposed example refers to a population that exhibits a logistic growth model, Where the principal limiting factor is food availability
N is the total size of the populationNt the population size after a T timeK the carrying capacityr the population growth rate per capitaWhen N < K the population has not reached the maximum size that can be supported by the environment. It can increase in size.
When N = K the population has reached the maximum size that can be supported by the environment. It can not grow anymore. The population reached a maximum point delimited by available resources, such as food
When N > K the population has supered the maximum size that can be supported by the environment. It must decrease in size. because there are not enough resources.
To calculate the population size after one year, we need to use the following equation.
N t+1= Nt+rN(1-N/K)
Available data:
K = 4500
N = 3652
r = 0.28
Nm= 4000
N/K = 3652/4500 = 0.8115
r.N = 0.28 x 3652 = 1022.56
N t+1= Nt+rN(1-N/K)
N t+1= 3652+1022.56(1-0.8115)
N t+1= 3652+1022.56(0.1885)
N t+1= 3652+192.753
N t+1= 3844.75
rounding up to 3845
What happens in an endothermic reaction?
Answer:
In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products. Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture.

b. a decrease of the biodiversity of an ecosystem
C. the biodiversity of an ecosystem experiencing no change
d. an ecosystem becoming more stable
A decrease of the biodiversity of an ecosystem is one of the prime cause for a reduction in ecosystem productivty.
What is ecosystem productivity?Productivity in ecology signifies towards the rate of generation of biomass in an ecosystem. Generally it is articulated in units of mass per volume per unit time. A decrease in biodiversity is one of the major cause of a decrease in ecosystem productivity.
The loss of biodiversity generally takes place by five prime factors:

Answer:
C
Explanation:

Mediterranean climate has cool and rainy winters. Therefore, option C is correct.
What is the Mediterranean climate?Mediterranean climate, a major Köppen climatic type with hot, dry summers and cool, wet winters, is found on the western sides of the continents between 30° and 45° latitude north and south of the equator. Seasonal changes occur because of changes in ocean currents.
Strong wind systems, severe precipitation, Mediterranean cyclones, and a significant seasonal difference in temperature and rainfall are some of the distinctive regional characteristics of the Mediterranean climate. This climate has only two seasons and that is summer and winter. Winters are shorter than summer.
Thus, the Mediterranean climate has cool and rainy winters. Therefore, option C is correct.

d. Pluripotency markers
Explanation:
Pluripotency can be defined as the capacity of individual cells to differentiate into any cell type. Pluripotent transcription factors are pluripotent proteins that promote the differentiation of embryonic stem cells (ESCs) into stem/progenitor cells by inducing the expression of target genes, which are also capable of maintaining their pluripotent state. For example, SOX2, OCT4 and NANOG are pluripotent transcription factors highly expressed in ESCs in order to maintain the pluripotent state of these cells.
