Answer:
The daughter cells have different DNA than their parents.
Answer:
The correct answer will be option A.
Explanation:
The electrical impulses are generated in the sino-atrial node or SA node, a mass of cells which generates impulse in the upper atrium.
This electrical impulse transmits from the sino-atrial node to the atrio-ventricular node in the lower portion of the upper atrium through the internodal pathway- the pathway composed of atrial cells.
Once the impulse reaches the AV node, it is transferred to the ventricular portion of the heart through Bundle of His presence in the ventricular septum. This bundle of his divides into left and right ventricles through bundle branches and stimulates both the ventricles.
Thus, option-A is the correct answer.
False, because most organisms decompose fairly quickly after they die. For an organism to be fossilized, the remains usually need to be covered by sediment soon after death. hope this helps :))

Answer:
Translocation
Explanation:
Translocation is a chromosomal defect in which part of a chromosome breaks off and reattaches backward on the same chromosome.
Translocation can happen due to many reasons like:
A) Some of the changes that arise around the time of conception or production of sperm or egg.
B) The inheritance of altered chromosome from father or mother.
Translocations can be divided into two forms:
- Reciprocal translocation
- Robertsonian translocation.
In reciprocal translocations, fragments of two chromosomes break off from two different places, break and swap each other's segments. While in Robertsonian translocation one chromosome attached with other.
Hope it help!
