Answer – B (Electrons)
When atoms combine, their nucleons fuse to produce a new nucleus and interactions occur between their electrons, particularly the outer valence electrons. The interaction between the outer valence electrons of the combining atoms forms bonds between them.
Answer:
20 million years
Explanation:
If we have a neutral mutation rate of one mutation per 5 million years, then the total of eight mutation between the two different species would be 20 million years. This is because both species will have 4 mutations in those 20 million years, so combined, both by 4, will have 8 mutations between them. So few mutations on so much time will result in two species that are very similar to each other even after 20 million years of evolution, even making them hardly distinguishable, especially if it comes to defining fossil records from them both. A nice example of this are the members of the felidae (cat) family, which are all very closely related, and are almost identical, thus making it extremely hard to distinguish two species of the same or similar size by their fossils.

Answer:
1250 g=1.25 Kg
Explanation:
We are given that Jason has five fishes of equally massed lead fish weights.
Weigh of each fish =250 grams
We have to find the value of total mass of the five lead fishing weights
Total number of fishes=5
In order to find the total mass we will use unitary method
Total mass is obtained by multiplying the total number of fishes with weight of one fish
Total mass=
Total mass of five fishes=1250 g
1 kg =1000g
Then 1250 g=
Hence, total mass of five lead fishing weights=1250 g=1.25 Kg
