Answer:
GM crops can be described as the variety of crop plants which have been modified through the recombinant DNA technology.
GMO'S are used in agricultural crops to :
1) Increase the amount of nutrients in a crop plant: As the population of humans is rising enormously, we need more food to survive on. The production of GM crops allows more food with better nutrition quality to be produced in a shorter time. For example, Golden rice is a GM crop which has increased levels of Vitamin A in it to meet the needs of Vitamin A in under-developed countries.
2) Produce Disease Resistant Crops: GM crops are a way to produce disease-resistant crops which will be disease-free and hence help in raising the economy. For example, orange trees are being produced by this method which is resistant to citrus greening disease.
3) Pest Resistant crops: Growing pests resistant plants are one of the major concerns of recombinant crops as a wide variety of pests infect the natural plants. For example, BT cotton is being produced which is resistant to the combat bollworm pest.
Answer:
Al
Explanation:
To survive, plants and animals carry out cellular respiration to break down sugar in the presence of oxygen to release energy in form of ATP. But they also use photosynthesis to make their own food.
Between the vertebrae are small spaces known as intervertebral canals that allow spinal nerves to exit the spinal cord and connect to the various regions of the body. There are 5 major regions of the spine: Cervical: The 7 vertebrae in the neck form the cervical region of the spine.

sorry if I'm wrong but I hope it helps!
please make my answer brainliest!!
Thanks!!
Answer:
Chemical digestion
Explanation:
Mechanical digestion can only break up the food particles into smaller pieces. A chemical digestion process called enzymatic hydrolysis can break the bonds holding the molecular 'building blocks' within the food together.
