Answer:
A white-eyed fly is born into a population of brown-eyed flies.
Explanation:
In the example, a new mutation (i.e., white-eyes) has appeared in the progeny. In the case that this new mutation has adaptive value, it will be transmitted across generations and therefore will increase its frequency in the population
Answer:
Option-2
Explanation:
Paleoanthropology is interdisciplinary of broad studies called anthropology. Paleoanthropology refers to the study of ancient humans through fossil evidence.
Paleoanthropology involves the studies of fossils which allows associating the ancient life of humans and their forms. The scientist collect the fossils and look for the life style of humans in the primitive time and also studies how they evolved into modern humans.
Therefore, the Paleoanthropology deals with the identification of the ancestors of humans that once lived on the Earth.
Thus, Option-2 is the correct answer.
Answer: B. They allow for specific substance to travel throughout the cell.
Explanation: I know this because carrier proteins and channel proteins are some types of embedded proteins.
The mass of 3.41×10²⁴molecules of propylamine is 33.45 gms.
<h3>What is avogador's no. ?</h3>
Avogadro's number, the number of units in one mole of any substance (defined as its molecular weight in grams), is equal to 6.02214076 × 10²³.
<h3>How to determine the molar mass of compound ? </h3>
To this problem we first need to calculate the molar mass of the given compound. as follows:
3×12+1×9+1×14 = 59
In the next step, we simply apply the formula to calculate the mass of the compound. it is
No. of molecules ÷ Avogadro's no. × molar mass of the compound
3.41 x 10²⁴÷6.02×10²³×54= 33.43gms
Hence, the mass of 3.41×10²⁴molecules of propylamine is 33.45 gms.
