Answer:
A. Nuclear reactors increase thermal pollution
Explanation:
From the analogy provided in this context, we can vividly see that the author is suggesting that the use of nuclear energy causes thermal pollution.
- Nuclear energy is an alternate energy source as identified in the text.
- Since a huge amount of heat energy is generated and they are not all used up, they are released into the ecosystem.
- The earth is usually depicted as heat reservoir.
- Increased release of heat to the environment will cause thermal pollution.
- This increases the ambient temperature of water and degrades it.
Answer: Dogs are Biotic factors. They are usually domesticated and are house pets. Dogs are living creatures and need food and water to live. What is the abiotic factors of a dog? Abiotic factors are the nonliving parts of an organism’s habitat. These factors include sunlight, soil, temperature, oxygen, and water.
Explanation: Hope this helps :)
<h2>Gelatin </h2>
Explanation:
Gelatin is a differential medium which tests the ability of an organism to produce an exoenzyme, called gelatinase (this enzyme hydrolyzes gelatin)
When gelatin is at a temperature below 32°C (or within a few degrees thereof), it is a semisolid material and at temperatures above 32°C, it is a viscous liquid
When gelatin is broken down, it can no longer solidify and if an organism can break down gelatin, the areas where the organism has grown will remain liquid even if the gelatin is refrigerated
No the conclusion by student is not right because the tube must be runny after incubation followed by refrigeration to be considered gelatinase positive
Answer:
c) allowing an organism to adjust to changes in environmental conditions
Explanation:
A stimulus can be defined as any change in the external or internal environment that produces a corresponding response in the organism. These responses enable the organism to maintain an internal equilibrium (homeostasis). Gene expression in prokaryotes, which are the simplest forms of life, is highly regulated by environmental stimuli. Some examples of stimuli known to regulate gene expression patterns in prokaryotic organisms are light, water, pressure, temperature, etc.
The answer is palpitation.
