Q: Answer the following question given this paragraph: Humans need lipids for many vital functions such as storing energy and forming cell membranes. Lipids can also supply cells with energy. In fact, a gram of lipids supplies more than twice as much energy as a gram of carbohydrates or proteins. Lipids are necessary in the diet for most of these functions. Although the human body can manufacture most of the lipids it needs, there are others, called essential fatty acids , that must be consumed in food. Essential fatty acids include omega-3 and omega-6 fatty acids. Both of these fatty acids are needed for important biological processes, not just for energy. Q: Humans need lipids for many vital functions such as storing energy and forming what? Choices: - ionic bonds - zygotes - enzymes - cell membranes A:
A: cell membranes
Question: Answer the following question given this paragraph: Some bacterial autotrophs make food using chemosynthesis. This process uses chemical energy instead of light energy to produce food.

Answer the following question given this paragraph: The accessory structures also have lowered activity, generating thinner hair and nails, and reduced amounts of sebum and sweat. A reduced sweating ability can cause some elderly to be intolerant to extreme heat. Other cells in the skin, such as melanocytes and dendritic cells, also become less active, leading to a paler skin tone and lowered immunity. Wrinkling of the skin occurs due to breakdown of its structure, which results from decreased collagen and elastin production in the dermis, weakening of muscles lying under the skin, and the inability of the skin to retain adequate moisture. Many anti-aging products can be found in stores today. In general, these products try to rehydrate the skin and thereby fill out the wrinkles, and some stimulate skin growth using hormones and growth factors. Additionally, invasive techniques include collagen injections to plump the tissue and injections of BOTOX®️ (the name brand of the botulinum neurotoxin) that paralyze the muscles that crease the skin and cause wrinkling. Q: How does a reduced sweating ability affect elderly people? Choices: - loss of mental ability - extreme tiredness - less energy - extreme heat intolerance A:
**Answer**
extreme heat intolerance
