The risk of lung cancer death is no different between medium, low, and very low-tar cigarettes.

People who smoke low-tar cigarettes compensate the lack of tar by changing their breathing habits, for example, they will take deeper drags or hold the smoke in for a longer period of time,  basically negating the supposed " low-tar" effect.

which are structures of the excretory system? check all that apply. kidney, spleen, bladder, esophagus, ureter, urethra
Rashid [163]

The right answer is kidney, bladder, ureter, urethra.

The urinary tract is the device that allows the evacuation of catabolism products from the human body in a liquid form, the urine, and thus ensures the purification of blood and the maintenance of homeostasis within the body. organization. Also, it maintains the blood balance, the volume and the chemical composition of the blood. To do this it eliminates, among other things, the surpluses of certain minerals, called electrolytes, and returns to the blood the substances that are useful for the proper functioning of the organism (reabsorption).

Every day, a human being produces 800 to 2,000 milliliters of urine. The urinary tract is included in the excretory system (as the large intestine and the lungs).

This apparatus is a succession of retro- and subperitoneal organs: the two kidneys, the two ureters, the bladder and the urethra.

The general formula for an aldehyde is _____. rcooh rcho rcor r2co rch2oh
Musya8 [376]

The correct option is (b) RCHO

The general formula for an aldehyde is RCHO.

<h3>What is an aldehyde?</h3>
  • An organic molecule with the functional group RCH=O is known as an aldehyde. The functional group alone (without the "R" side chain) can be categorized as a formyl group or as an aldehyde.
  • Aldehydes are widespread and have significant functions in both the technological and biological worlds.
  • Aldehydes have a carbon center attached to oxygen via a double bond, hydrogen via a single bond, and a third substituent—usually carbon or, in the case of formaldehyde, hydrogen—by a single bond. It's common to refer to the center carbon as being sp2-hybridized. Aldehydes belong to a polar category.
