Answer:
a. an example of a transgenic tomato (also called GMO tomato)
Explanation:
Genetic modification is the process by which an organim's genome is manipulated in order to achieve a desirable feature in such organism. Also called genetic engineering, genetic modification involves using biotechnology to alter an organims genetic composition. The organism whose genome is manipulated is called GENETICALLY MODIFIED ORGANISM (GMO) or TRANSGENIC ORGANISM.
In this case, a tomato with a gene from a fish that helps the tomato resist frost damage is said to be an example of GMO or transgenic organism because the genome of the tomato plant has been manipulated by inserting a desirable gene (resistance to frost) into it.
Yannick's class measured the width of one leaf serval times the values that the class recorded included 10 mm 8 mm 15 mm 5 mm 13 mm. The several different widths indicate that the class lacked the understanding of the word 'width' of the leaf and a standard procedure to make the measurements. Since leaf has two axis of making measurements, along the vein and across the vein. The measurements made along the vein would be greater than that of the across the leaf stem. Also the point of measurement of the width across the vein would vary as leaf tappers by the tip. Hence they should have been instructed to measure the width across the vein by folding the leaf into two halves, so as to make the readings more relevant.
Answer:
Antibiotics are routinely introduced into the food of cattle, chickens and other livestock, which causes the animals to grow faster but the negative effect of using antibiotics is the development of antibiotic-
resistant bacteria.
When we use antibiotics at large scale some bacteria that live in these cattle become resistance to these antibiotics and then these resistant bacteria are shed in the soil through poop of animals.
Bacteria have the capability to transfer antibiotic-resistant genes to other bacteria by horizontal gene transfer mechanism so it can give rise to more antibiotic-resistant bacteria which can infect humans.
So when these resistant bacteria infect humans then if we take the antibiotics which the bacteria are resistant for then the antibiotic will not able to protect the patient.
Therefore, this practice could affect the probability of developing populations of antibiotic-resistant bacteria that cause human disease.
The desert.
Since the desert is made of sand, wind erosion can move deserts or parts of them entirely.
