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:
extreme heat intolerance

Answer the following question given this paragraph: As you can see in this NASA photo, Earth is tiny compared with the massive sun. The sun's gravity is relatively strong because the force of gravity between two objects is directly proportional to their masses. Gravity between the sun and Earth pulls Earth toward the sun, but Earth never falls into the sun. Instead, it constantly revolves around the sun, making one complete revolution every 365 days. Q: The sun's gravity is relatively strong because the force of gravity between two objects is directly proportional to their what? Choices: - tissues - Liquids - rocks - masses A:
(Answer)
masses
Ques: Answer the following question given this paragraph: In this lesson, you learned some of the ways that humans differ from other mammals. For example, humans have a larger and more complex brain than other mammals. That's why they are also the most intelligent mammals. The next chapter introduces the biology of the human animal. Q: What mammal is the most intelligent? Choices: - dog - monkey - lion - humans A:
Ans: humans

(A).
carbon and hydrogen
Ques:Answer the following question given this paragraph: Q: What controls every aspect of plant growth and development to some degree? Choices: - chlorophyll - pesticides - acids - hormones A:

Ans:hormones
Ques:Answer the following question given this paragraph: Symbiosis Symbiotic relationships, or symbioses (plural), are close interactions between individuals of different species over an extended period of time which impact the abundance and distribution of the associating populations. Most scientists accept this definition, but some restrict the term to only those species that are mutualistic, where both individuals benefit from the interaction. In this discussion, the broader definition will be used. Commensalism A commensal relationship occurs when one species benefits from the close, prolonged interaction, while the other neither benefits nor is harmed. Birds nesting in trees provide an example of a commensal relationship (Figure 45.25). The tree is not harmed by the presence of the nest among its branches. The nests are light and produce little strain on the structural integrity of the branch, and most of the leaves, which the tree uses to get energy by photosynthesis, are above the nest so they are unaffected. The bird, on the other hand, benefits greatly. If the bird had to nest in the open, its eggs and young would be vulnerable to predators. Another example of a commensal relationship is the clown fish and the sea anemone. The sea anemone is not harmed by the fish, and the fish benefits with protection from predators who would be stung upon nearing the sea anemone. Q: What is the term for interactions between individuals of different species over an extended period of time which impact the abundance and distribution of the associating populations? Choices: - parasitic relationships - cooperative evolution - food chain - symbiotic relationships A:

Ans:
symbiotic relationships
