Explain why blood type data cannot prove who the father of a baby is, and can only prove

Biology
1 answer:
Akimi4 [234]3 years ago
4 0

Explanation:

Although blood group studies cannot be used to prove paternity, they can provide unequivocal evidence that a male is not the father of a particular child. Since the red cell antigens are inherited as dominant traits, a child cannot have a blood group antigen that is not present in one or both parents.

One of the factored that contributed to the movement of plants from the water to the land is increased exposure to sunlight. Why
nevsk [136]

The correct answer is - because it increases production of glucose, which is the plants' food.

The main reason why the plants started to move from the water towards the land was that on the land they were able to produce more glucose, and the glucose is the food that the plants produce for themselves.

The increase of glucose production on the land was possible because the plants received more sunlight. The sunlight is crucial for the process of photosynthesis, in fact this process is not possible if there isn't sunlight. By using the sunlight, as well as gases from the atmosphere, the plants manage to create their own food, glucose, and the more they produce of it, the better for them, as they can grow more, live longer, and be in better condition.

A bacterium, containing one circular DNA chromosome, undergoes four rounds of replication. How many new strands of DNA would res
iVinArrow [24]

Answer:

The correct answer is 32 strands.

Explanation:

In bacterium, DNA replication is bidirectional which means it takes place in both directions. The origin of replication starts the replication, it is a specific sequence of nucleotides. Each strand of circular DNA acts as a parent strand to replicate its complementary new strand, resulting in two new DNA strands, one parent strand, and one new synthesized strand. So after the first round of replication, there are 4 strands formed.

Similarly, during the second round of replication each of the four strands will be synthesized lead to a total of 8 strands in the same manner. So by the same process in 3rd round will lead to 16 new strands and by the fourth round of replication 32 strands will be synthesized.

Thus, the correct answer is 32 strands.
