The table shows the minimum pH that some common freshwater organisms can survive in water. Which organism would be MOST sensitiv
JulijaS [17]

The correct answer is option B- Clams

It is very clear how acid rain is affecting our ecosystem. Plants, animals and other living organisms are effected including their habitat.  

When acid rain enters soil, it leaches aluminium from soil particles and mixes it with soil. Aluminium level in water intoxicates the water content which is critical for the survival of water animals.  

The critical PH level for clams is 6.

How can the allele be recessive when three children have the disease ?<br>(the answer is C )
Fed [463]
Both parents are normal. But, some of the kids have the disease. This indicates that the parents are heterozygous for the disease (let's use Dd). They are phenotypically fine because D is normal. But we know they must both carry the diseased d allele because their kids have the disease.
If you cross Dd x Dd you get DD, Dd, Dd and dd as the possible outcomes. But because each time they have a child they roll the dice as to which of the 4 above happens, they were unlucky as 3 of those times they got dd for their child...so 3 of them have the disease (and are dd). One is phenotypically normal but could still be Dd or DD.

Construction workers attach ropes and pulleys to wooden timbers on an old bridge.
balu736 [363]

Answer:

It is a safe and efficient method.

Explanation:

This method of dismantle the bridge is also a good one but there are some other methods also that are used instead of rope and pulley system such as destroy the bridge by using bombs at the base of pillars and cutting of each part in order to dismantle the bridge. This rope and pulley system is also an efficient way to dismantle the bridge so that's why the engineers used this method instead of other methods due to its safe method.

True or False? Understanding what motivates employees in different generations is becoming increasingly important for healthcare
JulsSmile [24]

Answer:

Yes it is true that understanding what motivates employees in different generations is becoming increasingly important for healthcare managers.

Explanation:

  • It is absolutely a wrong concept that employees are motivated by their salary or amount of money.
  • The motivation differs from person's personality, their age generation and many other factors.
  • An employee's motivation is dependent upon believe that they can execute the task and they will receive the valued outcomes.
  • So, heath care managers must be highly conscious about knowing their employee in term of their motivations and self satisfaction.
