Answer: Chromosomes
Explanation: Chromosomes contain a cell's DNA. When a cell divides, the chromosomes must replicate. There are two types of cell division. Chromosomes undergo a different process depending on the type of cell division. It is important that chromosomes replicate properly so that each resulting cell has the correct amount of DNA after division.
Answer:
3 is appropriate statement that describes photosynthesis
Animal cells each have a centrosome and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.
Genetically modified crops are produced through an organism that undergone changes in its DNA using the process of Genetic Engineering. Genetically foods are being generated and tested inside a laboratory. A natural tastes and feature of a food is being change into something different in tastes and feature.
Similarities and differences are explained below
Explanation:
Differences:
somatic nervous system:
- It is part of the peripheral nervous system associated with the voluntary control of body movements through the skeletal muscles and mediation of involuntary reflex arcs.
- It has sensory and motor pathways.
- It controls muscles and movement.
- System responses are based on skeletal muscle contraction.
Autonomic nervous system:
- The autonomic nervous system is subdivided into the sympathetic nervous system and parasympathetic nervous system
- It possesses only motor pathways.
- It controls glands and internal organs.
- This system works automatically, without a person's conscious effort.
Similarities between the somatic nervous system and the autonomic nervous system:
Both have motor pathways
Both the system use nerve impulse
Both the system Weaken Myocytes
Both the system use glucose as an energy source for the muscles that they control
Both the system are controlled by the CNS
Both possess neurons
