Answer:
Option c (
) is the correct alternative.
Explanation:
Given:
Common ancestor,
= 50 million years ago
Base differences,
= 92
Now,
The predicted mutation rate will be:
= 
= 
= 
or,
=
Thus the above solution is the right one.
Answer:
During the method of photosynthesis, daylight is employed to convert water and dioxide into aldohexose and gas. light-weight reactions convert the energy in daylight into the energy of ATP and NADPH.
a) In the bright daylight, the Calvin cycle happens within the stroma. throughout the Calvin cycle, the products ATP and NADPH are accustomed convert molecules of carbonic acid gas into high-energy sugars.
b)In the darkness, the Calvin cycle conjointly happens within the stroma. throughout the Calvin cycle, the products ATP and NADPH are used to convert molecules of CO2 into high-energy sugars.
c) There will be a decrease in the products ATP and NADPH if the plants are unbroken within the dark for a protracted time and also the Calvin cycle can't be continued.

Answer:
Joan Walks 
miles farther than maria
Explanation:
Given:
Distance walked by Nicole = 1. 11/12 miles
Distance walked by Tasha= 2. 1/12 miles
Distance walked by Maria = 1. 7 /12 miles
Distance walked by Joan = 2. 2/12 miles
To find:
How much farther Joan walks to school than Maria = ?
Solution:
We can find the distance that Joan walk more than maria by subtraction
Joan distance - maria distance
here the distance are given in mixed fraction , so lets covert them into fraction and perform subtraction
=> 
=>
=>
=>
=>
The answer is A. True.
Plankton includes a diverse group of organisms that live in the water but are not capable of active swimming against the water current. On the contrary, nekton<span> includes a diverse group of organisms that live in the water but are capable of active swimming without the help of the water current. A shark is capable of active swimming, therefore, it is the example of nekton.</span>
