almost all the countries depend on agricultural and production of crops for their development. they have achieved alots of benefits which couldn't be discribed but due to competition among the countries for development . resources are being exploited haphazardly without focusing in the conservation of natural vegetation.
<h2>Right answer: they are afraid to lose what they have</h2>
According to Suzuki people in northern countries do not share because they are afraid to lose what they have.
This excerpt was part of the speech Severn Cullis-Suzuki gave at the Rio Earth Summit held at Río de Janeiro, Brazil on 1992 when she was only a 12-year old girl.
In this context, Suzuki, being a child, addressed her speech to the adults at the summit, warning about the consequences of climate change and the apathy of people in this regard.
Answer:
All of the above is true about the waxing gibbous and waning gibbous moon.
Explanation:
The first option is correct because the waxing gibbous moon is lit up on the right, with the moon moving into full moon phase next, and then being followed by a phase where it is lit up on the left, known as the gibbous waning moon.
The second option is correct because the moon moves from the waxing gibbous phase toward the full moon phase, it is becoming more and more lit up, thus it gains light, while the waning gibbous moon phase comes after the full moon phase where it is becoming less and less lit up, thus loses light.
The third option is correct because the lit up part of the moon in both of these phases has an elliptical shape, with the elongated part being on the top and bottom side, thus giving it an appearance like a football.
The explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the Redshift- Doppler effect.
<h3>What is the Doppler effect?</h3>
The Doppler effect is the difference that occur between the frequency of a wave in relation to observer from the wave source.
The wavelength changes with change in the frequency.
<h3>How does the Doppler effect explain the redshift?</h3>
As an object moves away from Earth, the waves moves to the red end of the electromagnetic spectrum and becomes elongated. This results to the increase in wavelength.
Therefore, the explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the redshift-Doppler effect.
