Answer:
I think the answer would be lichens, because lichens are formed during primary succession as a pioneer species. During secondary succession, grasses are usually the pioneer species.
Answer:
Pyruvate kinase
Explanation:
Yeasts convert glycerol and sugars into glyceraldehyde 3-phosphate (G3P) through independent pathways. Then, G3P forms pyruvate and, in some circumstances, pyruvate is converted in ethanol, which can be used as energy sources. If the mutation affects any reaction before G3P formation, it will only affect yeast growing either on sugar or pyruvate but not both.
Pyruvate kinase is the only enzyme on the list acting after G3P is formed and before pyruvate is formed. All other options are enzymes acting only in the formation of G3P from sugars. Meaning that only pyruvate kinase mutants will lack the ability to grow on both sugars and glycerol.
Answer:
this is just evolution like the birds on the Galapagos islands also I don't see the question
DNA isolation is a process of purification of DNA from sample using a combination of physical and chemical method while on the other hand, Polymerase chain reaction (PCR<span>) is a technique used in molecular biology to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence.</span>
Answer choice: [C]:
_________________________________________
V = d / t = 1800 mi / 40 min = 180 mi / 40 min = 45 mi / min .
Which very well could be "Answer choice: [C]: 45 m/min" ; except, this answer choice may have been written incorrectly—and should read:
"45 m/min."
________________________________________________________
Now, notice that all the answer choices given are in "meters" per (unit time—seconds or mins.
So, we need to convert:
45 mi. to "meters", or "m".
______________________________________
Note the following conversions:
_______________________________________
1 mi. = 1750 yd
______________________________________
3 ft. = 1 yd.
____________________________________
1 m = 3.2 ft.
_____________________
So, 1 mi. = ? m ;
_____________________
1 mi * ( 1760 yd/ mi) * (3 ft / 1 yd) * ( 1m / 3.2 ft) = _?_ m ?
_____________________________________________________
On the "left hand side" , the units of "mi", "yd", and "ft" ; cancel to "1" ;
____________________________________________________
and we are left with:
______________________________________
[(1760 * 3)] / [(3)*(3.2)] m = (5280 / 9.6) m = 550 m .
______________________________________________
So, we have: 550 m / min ; which match NONE of the answer choices.
However, it is possible that choices A or B, which are given in "m/sec" (meters per second); are among the correct choices.
____________________________________________
So, we convert: 550 m / min to: "m / sec " ;
______________________________________
( 550 m/ min)*(1 min/ 60 sec) = (550/60) m/sec = (55/6) m/ sec
= 9 1/6 m / sec .
_____________________________________________________
which is: None of the above.
______________________________________________________
Unless the answer choices were written incorrectly.
