Usually static electricity is present in balloons when rubbing them together. There is often an imbalance of positive and negative charges in the balloons which causes the static electricity.
Answer:
C
Explanation:
The DNA in all the cells of an organism are the same. The reason there are different types of cells in the organism even through their DNA is the same is because genes are deferentially expressed in the cell types. The genes that are expressed in the brain cells are different from those expressed in the liver. The rest of the genes that are not being expressed are silenced through folding by histones – so they are not exposed to DNA polymerase.
Answer:
Option (B)
Explanation:
The equator is the imaginary line that divides the earth into two equal halves, The distance from the equator to both the poles are equal. The equator passes through the 0° latitude. The region in and around the equator receives the maximum amount of sunlight emitted from the sun.
This equator is the line of longest latitude and its total length is nearly 24,901.6 miles.
Hence, the correct answer is option (B).
Answer:a hydrocarbon reacts with oxygen
Explanation:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. During reproduction, when the sperm and egg unit to form single cell for sexual reproduction. During reproduction, when the sperm and egg unit to form a single cell, the number of chromosome is restored in the offspring.
Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome. The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
