Answer:does anyone know the answer
Explanation:
Answer:
a) interphase(G2)
Explanation:
<em>The nucleus would contain 6 pg of DNA at the interphase (G2) phase of the cell cycle.</em>
The cell cycle is characterized by tow main phases, namely;
- The interphase
- The m phase
The interphase is divided into G0, G1, S, and G2 phase respectively while the m phase is divided into prophase, metaphase, anaphase and telophase respectively.
At the S phase of the interphase specifically, DNA is replicated and the amount of DNA in the cell becomes double.
<u>Hence, a cell whose DNA amount ranges from 3 - 6 pg will have exactly 6 pg after the S phase of the interphase, which is G2 phase.</u>
The correct option id a.
Cerebellum smoothes and coordinates the movement of skeletal muscle.
In the area of tissue and organ bio-engineering, scientist have been able to create simple tissues like cartilage. However, they are yet to accomplish in creating complex organs such as heart and lungs. There are many complications while creating heart, lungs and kidney because they have complex structure, different types of cells and also varied functions.
However, creation of windpipe is an achievement as many infections can be cured. Thus, tissue engineering is an emerging branch of science which also needs advanced technology and huge investment.
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
