My 2 cents below, I tried to think through the other ones:
A. Yes, because an amino acid change has occurred.
(A gene mutation occurred, not an amino acid change)
B. Yes, because all mutations change the resulting protein.
(Sounds correct. Gene -> mRNA -> protein)
C. No, because the amino acid sequence has not been changed.
(The gene mutation means the amino acid sequence <em>has</em> changed)
D. No, because mutations in the DNA do not affect the mRNA sequence.
(They do so)
Answer:
a new fossils are constantly being discovered
Explanation:
Answer:
A) Phanerozoic
Explanation:
In the given question, the chart about the evolution of insects has not been provided but based on the previous knowledge, this question can be answered.
The geologists have divided the time scale into many variables in which Eon represent the longest time scale period which has lasted for the millions of year.
The Phanerozoic eon represents the time scale during which first visible life evolved and began around 542 million years ago and is present until today. The insects belong to the arthropod group which evolved during a smaller time scale called Devonian period.
Since the insects evolved around 479 million years ago which falls under the Phanerozoic eon, therefore, phanerozoic is the correct answer.
Thus, Option-A is correct.
Answer:
monosaccharides!
Explanation:
- these are basic unit or simple sugar that make up the more complex sugars such as oligosaccharides and polysaccharides
- monosaccharide is a greek word ,mono meaning singular and sacchar means sugar
general formula:-
(CH2O)n,where n is 3 or greater than 3
- it is the most abundant sugar in nature
- It is present in different fruits and vegetables
In the terms of energy transfer what predator and prey face in there relationship is typically a food chain. Due to the fact that prey get food from the lowest on the food chain which since the prey has eaten it gets "energy" from the food it ate and the predator would eat the prey hence gathering energy from the prey which it gained from a different food source.
Take care and have a wonderful day
