It is to be noted that the current rates of extinction as relates to certain animals and plants species show the rates to be higher than the mass extinctions at the end of the Cretaceous Period.
<h3>What is the rate of extinction?</h3>
Rates of extinction simply refer to how quickly species are becoming non-existent.
The rates are said to be on the average of 100 E/MSY. In 2020 for instance about 15 species (according to IUC) were declared extinct.
E/MSY is Extinctions per Million Species-Years. The correct answer, thus, is C.

Answer:
<em>C. The individual unit owner</em>
Explanation:
Based on what you actually own, your maintenance responsibilities for the property – and therefore your repair costs, and so on – will vary.
Normally, a unit owner is made responsible for managing all that is a part of his unit system.
For instance, if you identify a "unit" in your condominium complex to include the outside shutters on your windows, it will be your responsibility to maintain that.
If they collapse off from each other a few years after you move in, you probably won't be able to get help from the home owners association (excluding proof that they were defective at first).
Answer:
a. increasing job enrichment by establishing client relationships
Explanation:
The job enrichment is the technique for motivation which is given by the business organization with the view that the employee performs his best by giving him additional responsibilities so that the organization can achieve its targets in an efficient and effective manner.
The self -reinforcement is that technique for motivation in which the employee motivates himself so that he is able to work in the best manner.
The job rotation is that technique for motivation in which the employee assigned the two or more tasks in different rotations
Job specialization means that the person who has the interest will take that department. Example - marketing, finance, human resource
The job feedback is given by the employee regarding the salary package, working environment, benefits, etc
Hence, in the given situation the most appropriate option is a.
Answer:
A. Review the budget to identify other areas where costs can be cut.
Explanation:
In the case when the vendor increased the material cost that planned and the increased cost would also be placed in your project i.e. over budgeted so the first thing you should do is review the budget by identifying the areas where the cost cutting to be done
Therefore as per the given situation, the option A is correct
And, the rest of the options are incorrect
Answer:
a. radius = 0.0006m = 0.6mm and length =0.393m = 393mm
b. frequency =377.86Hz
Explanation:
Given:
mass of steel= 4g = 0.004kg
density of steel = 7890kg/m3
tensile stress of steel 7.0x10⁸
tension load =900N
from the density, we will calculate for the Volume of the steel string
density = mass/volume
volume = mass/density = 0.004/7890 = 5.07 x 10⁻⁷ m³
from the tensile stress will can get the maximum base Area of the string ,
tensile stress = load/area =
7x10⁸ = 900/A
A = 900/7x10⁸ = 1.29x10⁻⁶ m²
Area = πr²
area/pi = 4.105x10-7
radius = 0.0006m = 0.6mm
volume = Area x length
length = vol/area =(5.07 x 10⁻⁷ m³)/1.29x10⁻⁶ m² = 0.393m
b. the highest possible frequency is given by:
F = 
where T= tension, m=mass, L=length
F = 
= 297.04/0.786
frequency =377.86Hz
