Answer:
The correct answer is: exonuclease activity.
Explanation:
DNA Polymerase is an enzyme of critical importance for the replication of the DNA. DNA needs to be replicated so, when entering Mitosis, each daughter cell can have a copy of the genetic material they need.
DNA Polymerase has an exonuclease activity in which mismatched nucleotides are removed from the newly replicated DNA strand in order to prevent mutations that can lead to malfunctioning or harmful proteins.
It is a tectonic plate, it is constantly moving and shaping the Earth's crust.
Answer:A. the same number of chromosomes as was contained in the zygote.
Explanation:a zygote is formed when the sperm fertilize the egg .
After fertilization,the zygote undergoes cleavage.cleavage is the mitotic Division of the cells of a zygote to produce daughter cells.
These daughter cells are called blastomere,which contains the same number of chromosomes as the parent cells.the cells formed do not grow in size but continues to divide, forming a mass of cells.
This mass may be solid at first but as cleavage continues,the cells move away from the center,leaving a fluid filled cavity in the middle (blastocoel).
The mass of cells are called blastula.
Answer:
Energy is transferred from the sun to Earth via electromagnetic waves, or radiation. The heat you feel in your body is the suns energy entering your body from the energy transfers that happen when you move.
Explanation:
Most of the energy that passes through the upper atmosphere and reaches Earth's surface is in two forms, visible and infrared light. The heat you feel in your body results from the energy transfers that happen when you move. When you sweat, your body expends energy to cool itself down. A food chain shows how energy flows from one organism to another. In general, energy flows from the Sun to producers and then to consumers.
