3. An agriculture specialist is hired by the U. S. government to help develop a new species of
carrot. The government would like a carrot that can be farmed and sold across the country
in an effort to help boost the economy. They provide him with a species of carrot from the
South that is popular because of its sweet taste and a species from the North that can
survive in cold temperatures. Describe one way the ecologist could develop carrot that is both sweet and resistant to the cold.

The ecologist can develop a sweet, cold-resistant carrot through genetic engineering.

Explanation:

To create a sweet and cold-resistant carrot, it will be necessary for the ecologist to extract the DNA from the southern carrot and the northern carrot, then it is necessary to do a sequence of the two DNAs, so that the ecologist identifies the region of the DNA , responsible for the genes that determine the characteristics that make one carrot sweet and the other resistant to cold.

Once these genes are found, it is necessary that there is a cut in the DNA of the genaras, in the regions where these genes are found. After that, it is necessary for these genes to be introduced into the DNA of a carrot plant. This introduction is made through Genetic Transformation Techniques, where the isolated genes are inserted into cells of this plant.

This cell (which contains the "sweet" and "cold resistant" genes) will be given all the requirements for it to multiply, giving rise to other cells with these genes, which will give rise to other cells that will continue to multiply until originate a carrot plant with the genes "cold resistant" and "sweet" and will form carrots with these genes.

economic impact of malaria is estimated to cost africa $12 billion every year. this figure factors in costs of health care, absenteeism, days lost in education, decreased productivity due to brain damage from cerebral malaria, and loss of investment and tourism.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
