Answer:
The correct answer will be option-B
Explanation:
Locus coeruleus is a nucleus composed of neurons in the pons region of the brainstem. The pons and brainstem are involved in the physiological responses of panic and the stress conditions.
Nor-epinephrine is the hormone which is produced in the stress and fear conditions and produces fight or flight response. The nor-epinephrine is produced from the adrenal medulla in the kidney and the brain. The part of the brain involved in the production of Nor-epinephrine is locus coeruleus.
Thus, Option-B is the correct answer.
Genes provide information for building proteins. They don’t however directly create proteins. The production of proteins is completed through two processes: transcription and translation. Transcription and translation take the information in DNA and use it to produce proteins. Transcription uses a strand of DNA as a template to build a molecule called RNA. The RNA molecule is the link between DNA and the production of proteins. During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein building machines. Through transcription the sequence of bases of the DNA are transcribed into the reciprocal sequence of bases in a strand of RNA. Through transcription the information of the DNA molecule is passed onto the new strand of RNA which can then carry the information to where proteins are produced. RNA molecules used for this purpose are known as messenger RNA (mRNA). A gene is a particular segment of DNA. The sequence of bases in for a gene determines the sequence of nucleotides along an RNA molecule. Only one strand of a DNA double helix is transcribed for each gene. This strand is known as the ‘template strand’. The same template strand of DNA is used every time that particular gene is transcribed. The opposite strand of the DNA double helix may be transcribed for other genes. During translation, the information of the strand of RNA is ‘translated’ from RNA language into polypeptide language i.e. the sequence of nucleotides is translated into a sequence of amino acids.
A lot of informations but I hope this helps ;)
The nervous system<span> is like a highway along which </span>your <span>brain sends and receives information about what is happening in the body and around it. This highway is made up of billions of nerve cells, or neurons (say new-rons) which join together to make </span>nerves<span>. A nerve is a fibre that sends impulses through the body.</span>
Hi friend,
the answer is HYPOTONIC
The as the solvent from the cell will move from hypotonic solution(inside) to hypertonic solution(outside).
AT equilibrium the outside will be hypotonic
HOPE THIS HELPS!!
Abiotic features are not living. they may play a role in helping biotic creatures live, but them theirselves do not live.
