2.) 19. Which of these processes is important in increasing genetic diversity in
organisms?


Answers

Answer:

its either meiosis or mitosis i cannot remember which though

Explanation:

The process that is important in increasing genetic diversity in organisms is meiosis, and in this process, the genetic diversity is seen due to the genetic crossing over and the recombination.

What makes meiosis important for the organism?

Meiosis is the process in which the parent cell makes the gametes that are haploid in nature; the male makes the sperm and the female makes the ovum in this process, and each of these gametes contains half of the genetic materials of the parent. Because meiosis results in genetic diversity in nature, it is important for the organism that produces offspring through sexual reproduction, and genetic diversity is seen in animals due to this process.

As a result, meiosis is an important process for increasing genetic diversity in organisms, and genetic diversity is visible during this process.

Which of the following is NOT true of Chlorophyll?
A) It reflects all the colors of light but absorbs the green.
B) It reflects the green wavelengths of light and absorbs all the rest.
C) It is essential for photosynthesis?

Answers

Answer: A.It reflects all the colors of light but absorbs the green.

Explanation:

Photosynthesis, which gives plants their green hue, requires chlorophyll. Therefore, option (A) is not true.

What is chlorophyll?

Chlorophyll, the pigment that gives plants their distinctive green hue, is crucial to the process of photosynthesis, which provides energy for a plant's metabolism, growth, and reproduction. Because chlorophyll does not absorb the green wavelengths of white light, it is chlorophyll that gives plants their green hue. The plant appears green because it reflects that particular light wavelength. Autotrophs are plants that produce their own sustenance through photosynthesis.

The stroma, which is the area between the thylakoid and chloroplast membranes, is where the chlorophyll, the green pigment, is found.

The Gulf of Mexico dead zone that forms each summer at the mouth of the Mississippi River is caused largely by the input of agricultural fertilizers that stimulate phytoplankton blooms, which die, and are subsequently consumed through bacterial decomposition. Decomposition consumes oxygen, leading to very low dissolved oxygen levels and subsequent death or emigration (i.e. leaving the area) of fish and other marine life. Many scientists advocate creating wetlands (as well as restoring them) as a strategy to reduce the severity and extent of the dead zone. The idea is that the plants in the wetlands will remove these nutrients from the water (during growth) and prevent their washing into the river and the Gulf of Mexico. Would the use of created wetlands be considered biotechnology

Answers

Answer:

Yes; the use of created wetlands would be considered biotechnology.

Explanation:

The created wetlands will employ the use of scientific tools and techniques, which will largely modify the plants, animals, and microorganisms in the Gulf of Mexico's dead zone.  Generally, it has been established that biotechnology allows farmers to grow more food with environmentally sustainable farming techniques, which also improve soil conservation.

Answer:

Yes, the use of created wetlands would be considered biotechnology.

Explanation:

Biotechnology uses biological systems and living organisms to develop and create different products. The new wetland that they create will be made with the usage of scientific tools and techniques in order to replicate an already existing biological system. It will have very modified plants, animals and other organisms in the Gulf of Mexico's dead zone.

is the energy an object has because of the movement of its molecules.
A. Heat
B. Thermometer
C. Particles
D. Temperature

Answers

The answer is temperature.

Molecular movement is considered kinetic energy, and temperature measures kinetic energy.

Temperature is a measure of kinetic energy because molecular motion is regarded as kinetic energy. The average kinetic energy of the molecules in a gas increases as its temperature rises, resulting in more motion. Thus option D is correct.

What is  kinetic energy?

A particle or an item that is in motion has a sort of energy called kinetic energy. An item accumulates kinetic energy when work, which involves the transfer of energy, is done on it by exerting a net force.

The molecular kinetic energy rises and the molecules start to move faster when heat energy is added to a system.

By increasing the temperature, the velocity of the particles is accelerated.

In contrast, lowering the temperature slows down the motion of the particles until it eventually stops entirely at absolute zero (0 K). The particles will have kinetic energy since they are moving.

Therefore, Temperature is the energy an object has because of the movement of its molecules.
