<span>The first desirable trait that is being engineered into our crops is sustainability. This means that crops are being bred to be able to grow in adverse conditions, ensuring the ability to sustain our food supply as humans. The second, are the alterations being genetically done to crops to eliminate the need for pesticides. By heightening the crops natural ability to eliminate and deter pests, there are higher yields and the elimination of pesticides seeping into and poisoning the human consumer. And, finally an ability to eliminate the need for traditional breeding in crops. By genetically replicating plants, we are eliminating the chance that the human race may "run out", of seeds, of starts, of the need for pollination. This basically ensures us an unlimited food supply, just in these three traits being bred into our crops.</span>
Answer: Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
Explanation:
The phase in the cardiac cycle when the mitral valve is closed and the aortic valve is open is the systolic ejection phase (Option D). It is the second phase of the ventricular systole.
The cardiac cycle is a sequence of contraction and relaxation of the atria and ventricles to pump blood throughout the body.
This cycle (cardiac cycle) can be divided into two major periods: diastole and systole.
The diastole is when the heart relaxes and refills with blood, while the systole is when the heart contracts and pumps blood.
The systolic ejection phase is the second phase of the ventricular systole where blood is pumped from the ventricle.

Answer:
The annual average CO2 concentration for 2021 could be around 416.3ppm, according to Meteorological Office estimates. An annual rise of about 2.5 ppm is possible, which can potentially make 2021 the first year with the annual average CO2 at 50 per cent above pre-industrial levels, the estimates noted
