Answer:
Motor nerves
Explanation:
Pulling the leg quickly from the sharp object is an example of reflex action. It includes sensory receptors, sensory neurons, interneurons, the control center (spinal cord), motor neurons and effector.
As soon as she steps on the glass piece, the receptors present in the skin of her foot sole sense it and send the information to the control center via sensory neurons. The spinal cord commands the muscles of the effector organ (leg) via motor neurons to move to step away from the glass piece.
Explanation:
Replication is the way to perpetuate genetic information, and ensure a faithful copy of the information in each of the cells produced by division. Regarding the transmission of information within the cell, the fundamental steps are two.
The first step, transcription, consists of the exact copy of one of the strands of DNA to RNA; the RNA sequence will be exactly the same as that of the copied DNA, except for the presence of uracil (U) instead of thymine (T).
The second step, translation, involves the synthesis of proteins using the genetic code, which identifies specific amino acids from a set of three bases.
The three processes mentioned are polymerization processes, which can be divided into three stages: Initiation, elongation and termination, defined in each case by specific events.
Between transcription and translation, in some cases there is a processing of transcripts in order to obtain mature messenger RNA (mRNA). Translation products are also processed. In each case, signaling elements are involved in the molecule that carries the information (DNA, RNA or protein) to give rise to a correct copying or processing.
Answer:
If there is no atmosphere the sun rays will directly come to us and it will damage our eyes. and we cannot fly rockets also..
Occasionally, chromosomes fail to separate during meiosis, leading to aneuploidy. It is an aberration in the number of chromosomes.
<h3>What is aneuploidy?</h3>
Aneuploidy can be defined as an aberration in the number of chromosomes in a given cell.
Aneuploidy occurs when chromosomes are not correctly separated during cell division (either mitosis or meiosis).
A common aneuploidy is a trisomy, where a diploid cell has three homo-logous chromosomes instead of two.
