Complete the following sentence. Iron usually forms only an _____
magnet that loses its
magnetism when moved away from a magnetic source. What one word completes the sentence?
Enter your answer

Answers

Answer 1
Answer:

Answer:

Temporary or Induced Magnets.

Explanation:

  • Temporary magnets: These magnets are made of soft iron that has temporary magnetic properties. These magnets behave as permanent magnets when introduced to a magnetic field but lose magnetism when moved away from the magnetic source.
  • Temporary magnets are usually used in radio, electric motors, phones.
  • They are extensively used as electromagnets to produce electricity.
  • The demagnetizing property of electromagnets by altering the intensity of electric current helps in a lot of practical applications based on controlled situations.

Assume that you transform bacteria with a plasmid containing an ampicillin-resistance gene. Instead of directly plating the transformed population as you did in this lab, you set up two liquid cultures of them, one that contains ampicillin and one that does not. You will then assay these cultures on plates at two different times: immediately after you set up the cultures, and then again after the bacteria have been in culture for an extended period. The assays will demonstrate the number of ampicillin-resistant vs. ampicillin-sensitive culture bacteria in each culture at each time. To perform each of the two assays, you prepare serial dilutions of the two cultures and plate them onto LB plates with and without ampicillin (the dilution) is simply to ensure that you will get some plates on which you can distinguish separate colonies).Describe what you expect to observe in the initial assay and in the second assay. What, if any, differences might you expect in terms of the ratios of ampicillin-resistant and nonresistant bacteria?

Answers

The answer is ATP loses one phosphate group and converts to ADP.

ATP stores potential energy in the form of chemical bond. By breaking this bond and removing one phosphate group from ATP, which is then converted to ADP, great amount of energy is released and it is ready to be used.

Select the appropriate statement about healing wounds.A) Cell growth increases both toward the beginning and the end of the healing process.
B) Cell growth increases toward the beginning of the healing process and slows down towards the end of healing process.
C) Cell growth slows down toward the beginning of the healing process and increases towards the end of the healing process.

Answers

The most appropriate statement about healing wounds from the choices given is "cell growth increases both toward the beginning and the end of the healing process." The correct answer is A. 

Answer:

The correct answer is statement A.

Explanation:

At the time of the process of healing, the skin's inner layer gets exposed and can lead to infection, as the microbes like bacteria can invade the wounded region. Thus, in order to cope up with the condition, the body enhances the growth of the cell in that specific region so that the wound get heal quickly.  

However, at the same time, in the end, the body produces various cells in order to seal up the wound. In the end, the formation of scar tissue takes place as the wound gets closed, thus, more tissue formation takes place in comparison to what was present prior to the formation of the wound. Thus, the correct statement is the first one.

_ is a term that describes the number and variety of species that live in an area. a. sustainability
b. ecological footprint
c. agriculture

Answers

Answer:

Biodiversity

Explanation:

The three options given don't seem to be correct...

Sustainability is how biological systems remain diverse and productive.

Ecological Footprint is the impact of human activities measured in terms of the area of biologically productive land and water required to produce the goods consumed and to assimilate the wastes generated.

Agriculture is the science of raising plants and/or animals for food, clothing or other useful products or the practice of cultivating the land or raising stock.

Final answer:

Biodiversity is a term that describes the number and variety of species that live in an area. It contributes to the stability and balance of ecosystems and provides ecosystem services.

Explanation:

Biodiversity is a term that describes the number and variety of species that live in an area. It refers to the variety of life on Earth, including plants, animals, and microorganisms. Biodiversity is important because it contributes to the stability and balance of ecosystems, and provides ecosystem services such as pollination, nutrient recycling, and water purification.

The nitrogen cycle _________. A. indicates the process of uptake of nitrates (NO₃ minus) by plants.
B. marks transformation of ammonium (NH₄ plus) into nitrites (NO₂ minus) by bacteria.
C. marks synthesis of ammonium (NH₄ plus) by decomposers.
D. marks transformation of nitrogen (N₂) from the atmosphere to ammonium (NH₄ plus) by bacteria.
E. marks organisms that take part in transformation of nitrogen from the atmosphere (N₂) into ammonium (NH₄ plus) and are located in the root nodules.

Answers

Answer:

D. marks transformation of nitrogen (N₂) from the atmosphere to ammonium (NH₄ plus) by bacteria.

Explanation:

The nitrogen cycle is a biogeochemical cycle which involves transformation of atmoshperic nitrogen into many chemical forms including nitrite (NO2), nitrates (NO3) and ammonium (NH4).

The process of nitrogen cycle starts with the process of nitrogen fixation. In this process several nitrogen fixation bacteria such as cyno bacteria converts the atmospheric nitrogen into ammonium (NH4) in the soil. The resultant ammonium (NH4) can be directly used by plants or transform into nitrites or nitrates through nitrification process.

Hence, the correct option is D.
