Why can’t a gamete carry an ""hh"" instead of an ""hs"" or an ""Hh"" instead of a ""HS?

Answer:

HS and hs is more suitable because during reproduction, gametes fuse with another gamete and the sets of alleles from both combines which results in the standard diploidy requirement for growth of an organism.

Supposing the gametes were diploid, the two gametes will fuse to form a zygote which is tetraploidy. This brings about abnormalities most of the time in organisms which don’t support this ploidy system.

Urination is one of the key mechanisms for losing fluid from the human body
morpeh [17]

Answer;

The above statement is true

Urination is one of the key mechanisms for losing fluid from the human body

Explanation;

-The body's homeostatic control mechanisms ensure that a balance between fluid gain and fluid loss is maintained. Water or fluid loss from the body is undertaken by several mechanisms which mainly include urination and sweating. Others include; respiration and through digestive tract.

-The body loses water primarily by excreting it in urine from the kidneys. Depending on the body's needs, the kidneys may excrete less than a pint or up to several gallons of urine a day.

-About 1½ pints (a little less than a liter) of water are lost daily when water evaporates from the skin and is breathed out by the lungs.

-Profuse sweating, which may be caused by vigorous exercise, hot weather, or a high body temperature; can dramatically increase the amount of water lost through evaporation. Normally, little water is lost from the digestive tract.

Compare and contrast smoking vs. smokeless tobacco.
m_a_m_a [10]
Smokeless tobacco is classified as a stimulant
10x the amount of nicotine than cigarettes
harder to quit than cigarette smoking
much more addictive than cigarettes because of the nicotine and the fact it enters the blood stream through the gums makes it worse.

Chewing tobacco and dip is highly addictive because it contains as much nicotine as cigarettes. Once you are addicted to nicotine, you may be more likely to start smoking cigarettes too.
According to the Centers for Disease Control and Prevention, smokeless tobacco contains 30-plus chemicals known to cause cancer, including:
Tobacco-specific nitrosamines, which develop as tobacco is grown and processed.
Polonium-210, a radioactive element in tobacco fertilizer.
Polynuclear aromatic hydrocarbons, which develop when tobacco is heat-cured.
Harmful metals, including arsenic, mercury, nickel and lead.


Health consequences of smokeless tobacco
While it’s true that smokeless tobacco presents slightly fewer health risks than smoking cigarettes, it’s far from safe. Smokeless tobacco is known to cause cancer and other health conditions, including:
Bad breath and stained teeth
Bone loss around the teeth
Cheek, gum, mouth and tongue cancer
Early delivery and stillbirth if used while pregnant
Esophageal cancer
Gum disease
Heart attack
Heart disease
Nicotine poisoning
Pancreatic cancer
Stroke
Tooth decay and tooth loss
Smokeless tobacco can also poison children and pets, in some cases leading to death.
The connection between tobacco and alcohol
“Many people find it especially difficult to quit tobacco products if they use them while drinking alcohol,” says Dr. Prylinski. “We have eight neurotransmitters in our brains. When you drink alcohol, you increase the level of five of those neurotransmitters. When you smoke or use tobacco, you increase the other three. That’s why when you drink, you start craving a cigarette or smokeless tobacco.”
