Crude birth rate decreases when literacy rates go up.

Explanation:

  • Overpopulation is a major problem of many developing countries.one of the major reason for overpopulation is the improper family planning and unwanted child birth.
  • With increasing literacy people of the society will start understanding the adverse effect of overpopulation on the over all development of the country.
  • Increasing literacy will make people aware of contraceptives and other safety measure. Thus, preventing unwanted child birth and improper family planning.

Answer:

When literacy rates goes up then crude birth rates will automatically be decline

Explanation:

Crude birth rate refers to the number of births /1000 in a population. It doesn’t count the age and sex in a population.

General fertility corresponds to number birth of a women age between 15- 49 in a year.

Factors Affecting fertility Rates: Healthcare,Education

Healthcare: Improvement in  healthcare leads to drop infant mortality rate , knowledge of birth control measures and economic status have an impact on birth rates.

Education: Female literacy rate and knowledge of birth control and employment opportunities also decline crude birth rate.

What are 3 major pieces of evidence that prove different species are related?
Julli [10]

Three different ways the relatedness of species could be assessed is through:

<span>1.    </span>Their genotype. Similarity in DNA between the species is a good indication of their relatedness.

<span>2.    </span>Their phenotype. If the two species have similar body form and function, then there is a good possibility that they are related.

<span>The presence of intermediates, either living or in the fossil record, can show relatedness between two species.</span>

There is a healthy bacterial culture growing in the exponential phase . A technician wants to make a growth curve by making cell
emmainna [20.7K]

A) WHAT IS THE PROBLEM WITH HER PLAN?

Binary fission is one of the asexual process by which most bacteria reproduce, the binary fission brings about a doubling of the number in bacterial cells that are viable.

Generation time is that time that it will require for a cell population to divide and double, it is also known as doubling time. This Generation time varies among distinct organisms and also varies among culture conditions.

Take for instance,a fast growing bacterium that is under an ideal culture conditions has a doubling time of 20minutes and for the bacteria that is grown in a condition that is not so ideal,may have a doubling time of hours.

The major challenge/ problem with her plan is that as she takes the bacterial sample every 30minutes, and then hold the sample till the last sampling is done in the day,those bacterial cells that are collected in the initial intervals will then get divided and further gives a result that is false.

However,if those bacteria that are collected aren't stored in a culture environment that is standard,the bacterial cells may die off and thus will further bring about a false result.

2) CAN SHE DO ANYTHING TO IMPROVE THE ACCURACY OF HER RESULT?

Solution for rectifying the error in her plan;

She can go ahead and add 50-100 μl of formaldehyde to all the culture suspensions that she has and has taken every 30minutes.

As the formaldehyde will fix the bacterial cells,The optical density present in all those aliquots can then be retrieved/taken at the end of the day.

Looking at it alternatively, aliquot 1ml of the culture suspension at an interval of every 30 minutes,and then take the optical density that is OD at a wavelength of 600nm making use of spectrophotometer until the reason you get becomes static.

Which of the following types of models could be used to represent a cell?
hodyreva [135]

Answer: The answer is Computer Model

Many researchers have suggested that using computer models would be more advisable to use to predict the earthquake. Researchers believe that it would be easier to tell the reaction of many nuclear power plants. They want to reassess the safety measures that are being implemented by many nuclear power plants.
