Which of the following is false about DNA?

A. DNA is made up of units called nucleotides.

B. Any base can pair to any other base.

C. DNA contains the instructions to make proteins.

D. DNA is found in a cell's nucleus.

Answers

Answer 1

Answer:

b. any base pair can pair to any other base

Explanation:

Answer 2

Any base pair cannot pair with any other base, Adenine pairs with thymine and cytosine pairs with guanine.  

• The hereditary material in humans and almost all of the living species is known as DNA or deoxyribonucleic acid.  

• The majority of the DNA is present within the nucleus of the cell.

• DNA comprises the instructions to make proteins that helps to perform essential functions within the body of an organism.  

• Within the DNA, information is stored in the form of a code formed of four chemical bases, that is, Adenine, guanine, cytosine, and thymine.  

• The base pairs present within the DNA pairs up with each other, that is, adenine pairs with thymine only, and guanine pairs with cytosine, no other kind of pairing is found within the DNA. Each base of also attached with a molecule of phosphate  and sugar.  

• Together, a phosphate, base, and sugar are known as a nucleotide.  

Thus, statement B is incorrect.

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:

Invasive speciesHabitat lossOverexploitationClimate changePollution

A reduction in biodiversity results in a decrease in the stability of the ecosystem. As a change to one organism will exhibit a greater influence on the entire ecosystem.

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.

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.

Answers

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 capita

When 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

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.
