Answer: 
4 × 10^0 kg or 4×E0 kg.
Explanation:
Before delving into or solving the Calculation, let us check one or two things about worker bees. 
WHAT IS A WORKER BEE?. 
Bees generally are social insects living in an organized community and they consist of three castes which include; the drone bees, worker bees, and the queen bees. 
The queen bees are the female bees while the drone bees are the male bees.
The WORKER BEES are female bees too, but the only difference between them and the queen bees is that they (worker bees) do not reproduce like the queen bees. They are saddled with the responsibility of looking for food and maintaining the hive temperature.
Now to the question, the mass of a bee= 1 × 10^-4 kg. And there are 4 × 10^4 bees in hive. Therefore, the mass of all the worker bees in the hive together = (1 × 10^-4) × (4×10^4). 
==> 4 × 10^0 kg, or 4E0 kg.
 
        
             
        
        
        
The question is incomplete as it does not have the options which are:
a. The woman with stretch marks has a greater collagen-to-elastic fiber ratio.
b. The woman may have different gender babies.
c. The woman with less stretch marks has larger skin cells.
d. The woman without stretch marks has more cholesterol in her diet, which affects her cell membranes.
Answer:
The woman with stretch marks has a greater collagen-to-elastic fiber ratio.
Explanation:
The stretch marks on the hips, stomach and breast of pregnant women is a very common problem. These stretch marks appear pinkish in color which is very difficult to treat.
These stretch marks are the result of the collagen to elastin ratio which increases and stretches. This stretching happens due to the sudden or rapid increase in the weight of the body or the affected portion.
Thus, the selected option is correct.
 
        
             
        
        
        
The appropriate answer is B. Throughfall. These nutrients are transported via the process of throughfall where rain flows from leaves to the ground. Rainforests receive high annual rainfall. The leaves are also designed to funnel water to the ground soon after a shower. Leaves are equipped with drip tips to allow water to roll of leaves easily. Any particles deposited on leaves are going to be washed to the forest floor by frequent rainfall that occurs here.
