A. in DNA can result in dysfunctional protein productiona. Your answer is Point mutation
The correct answer is - 1,180 km.
North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.
To get to the result we only need to multiply the number of years with the annual movement
2 x 200,000 = 400,000
Than divide the result with 100,000, as that is how much cm are in one km
400,000 / 100,000 = 4
And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.
Mutations can cause instant adaptations, while natural selection is the process by which adaptations occurs over a series of generations. Adaptations are changes or processes of changes by which an organism or species becomes better suited for its environment. A mutation is an alteration of the DNA sequence.
Answer: C. meiosis produces sex cells that are joined during sexual reproduction to produce offspring
Explanation:
Meiosis is also called as reduction division in this the parent diploid cell divides twice to produce four haploid daughter cells. The daughter cells so produce after cell division contain half the number of chromosomes then that of the parent cells. The germ cells in males and females divide twice or meiotic division occurs in them twice to produce four daughter haploid gamete cells that are sperms (male) and ovum (oocyte) (female). These male and female gametes fuse during sexual reproduction. The sperm fertilizes an ovum to produce zygote.
If we have:
m₁ as the mass of the first satellite
m₂ as the mass of the second satellite
v₁ as the velocity of the first satellite before the connection
v₂ as the velocity of the second satellite before the connection
v₁' as the velocity of the first satellite after the connection
v₂' as the velocity of the second satellite after the connection
The momentum is conserved following this equation:
m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'
If the collision is perfectly elastic or the two satellites connect perfectly and move with a single velocity:
m₁v₁ + m₂v₂ = (m₁ + m₂)v'
where v' is the velocity of the two connected satellites
