It’s a sugar found in RNA but not in DNA
B. They vary in their distance from each other.
C. They are oriented perpendicular to each other.
D. The bases face each other rather than the backbones.
B. magnetic and gravitational fields
C. gravitational, electric, and magnetic fields
D. electric field only
Answer:Option C. gravitational, electric, and magnetic fields
Explanation:
An electron is a negatively charged particle having mass, m = 9.1 × 10⁻³¹ kg and charge, q = -1.602 × 10⁻¹⁹ C. Gravitational field is created all bodies having mass. Hence, a moving electron also creates gravitational field.
A charged body creates electric field around it. And when the charged body moves, it also creates magnetic field. Hence, a moving electron creates gravitational field, electric field and magnetic field.
Therefore, the correct answer is option C.
Answer:
Transposon is a fragment or sequence of DNA that can move unregulated to any point in the cell genome, leading to a phenomenon called transposition.
Explanation:
Transposon is the name of what was previously known as jumping genes, being a DNA sequence capable of moving freely within a DNA molecule. A transposon can produce mutations by translocation, altering the total amount of nucleotide in DNA molecule.
Genetic changes that are linked to evolutionary processes can be due to the existence of transposons, since they can even induce chromosomal changes.
Answer:
alveoli
Explanation:
The alveoli are small pockets present in the lungs. They are extremely important in the living organism, because the carbon dioxide that is excreted passes directly from the blood to the alveoli. These pulmonary pockets are located inside the lungs and originate through the bronchial branches, have a spongy appearance and vascularized walls.
It is in the alveoli that the gas exchange essential for living organisms occurs. The alveoli have a very thin membrane that separates air from blood, it is because of this membrane that carbon dioxide is excreted.
