Genetically modified foods are foods that have been engineered (changed/altered) to produce from the original food to have a change in DNA using genetic engineering. For example cotton candy grapes, there isn’t such thing as a real cotton candy grape, the flavor of the grape been modified to taste like cotton candy.

Answer: DESERT
Explanation:
Adaptation can be defined as the modification in the form, structure, function and behaviour of organisms in a habitat which enables them to live successfully and reproduce.
Desert is one of the types of the world biomes that is characterized with little or no rain and to extreme temperatures. Organisms, which includes plants and animals, must show some level of adaptation to able to survive the harsh environment.
The type of PLANTS which can survive in desert environment are called the XEROPHYTES. They show the following adaptations:
--> The roots are well developed: they grow down to great depths and branch extensively in order to absorb water
--> they possess swollen stems which contains water storage cells.
--> they have reduced leaves, for example in cacti in the form of spines, which helps to reduce water loss through transpiration.
The type of animal that survive in desert environment spend the hot dry seasons in a sleep-like torpid state called aestivation. This is so in order to avoid the heat. Their body size is usually small and less bulky: greater surface area in relation to body volume, thus enhancing heat loss from the body.
Organisms that live in the _________ must be adapted to little or no rain and to extreme temperatures.
Answer:
The Excretory System, The Reproductive System and The Endocrine System.
Explanation:
The Excretory System includes your bladder, uterus, and some of your organs. It is also called the "Urinary System". The Reproductive System includes your birth canal. This system helps to reproduce the body to have babies. The Endocrine System includes your hormones. It helps the body to depend on growth development or mood.
I hope this answers your question! :)
Answer: The genotype ratio of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant is 2TT:2Tt
The phenotype ratio is that all offsprings will be tall.
The genotype ratio of a cross between two heterozygous red flowers is 1RR:2Rr:2rr. The phenotype ratio is 3 Red flowers: 1 white flower.
Explanation: From the information given, tall is dominant and short is recessive while red is dominant and white is recessive.
Let T represent the allele for tall height, t represent the allele for short height, R represent allele for red flowers and r represent allele for white flowers.
The genotype of a homozygous tall plant is TT, the genotype of a heterozygous tall plant is Tt, the genotype of a heterozygous red flowered plant is Rr.
The possible genotypes of offsprings of a cross between one homozygous tall plant and one heterozygous tall plant are TT and Tt.
Tt will manifest outwardly as tall because T is dominant over t. Therefore, all the offsprings will be tall.
The possible genotypes of a cross between two heterozygous red flowers are RR, Rr and rr. RR will manifest as red, Rr will also manifest as red because R is dominant to r while rr will manifest as white because white allele (r) is recessive. Therefore 3 plants will be red-flowered while 1 plant will be white flowered.
See the attached punnet squares for details of the cross.
