Hey there!
The answer would be ultrasound.
The ultrasound is considered safe because it uses sound waves for the detection of tissue, organ, baby etc. These waves are considered safe and transfer only a small amount of heat to the tissue in which the ultrasound is done. A little amount of heat is not at all harmful to the body in any means. Early defects of baby can be detected through this procedure, the merits of the process is much higher than its demerits.
Hope this helps !
Answer:
However, plants are also able to reproduce asexually
Explanation:
Their purpose is reproduction.
Answer: a) substrate and cofactors b) covalent modification
Explanation:
Metabolic pathways involve all the chemical processes takes place in the enviornment or in an organisms.The metabolic pathways are controlled through the catalytic activities of enzymes.
The availability of enzyme is regulated by substrate and cofactors present in enzyme and enzyme activity is commonly regulated via covalent modification.
Enzymes are highly selective in nature and bind to a specific substarte only. The active site in enzyme binds with the substrate to form enzyme substrate complex. Coactors assist the enzyme activity, without cofactor enzyme can not perform its activity.
Hence enzyme availibility is regulated by substrate and cofactors regulates.
Covalent modifications regulates activity of enzyme as it involves addition and removal of chemical group to synthesis required protein. It can change the chemical properties of the site by targeting one or multiple amino acid.
Thus the correct answer is a) substrate and cofactors b) covalent modification
