The question is incomplete as it does not have the option which are:
A) 100, 7
B) 100, 14
C) 200, 7
D) 200, 14
E) 400, 14
Answer:
A) 100, 7
Explanation:
The ascomycetes reproduce by the forming ascospores which are formed by the process of meiosis thus from 1 Parent cell, 4 daughter cells are reproduced. The 4 ascospores then undergo the mitosis and 4 daughter ascospores form 8 ascospores.
If the parent cell of an ascospore contains
1. Ploidy- 2n=14 chromosomes, therefore, Meiosis process will reduce the number to half and will form the n=7 in daughter cells.
2. The DNA amount- in G2 stage will be 400 ng therefore during meiosis I, two cells with 200 ng DNA and then two more cells with 100 ng will be formed after meiosis II.
Thus, A) 100, 7 is correct.
Answer:
Soma or cell body
Explanation:
The cell body of a neuron is also called soma. Soma contains a nucleus surrounded by cytoplasm. Several cellular organelles such as lysosomes, mitochondria, and a Golgi complex are present in it. The presence of free and ER bound ribosomes allows cell bodies of neurons to form proteins for growth and regeneration of the damaged axons. Therefore, cell bodies serve as metabolic centers of neurons.
Dendrites of postsynaptic neurons obtain the nerve impulse from the axon of the presynaptic neurons and deliver it to the cell body. Axon of a neuron carries the nerve signals away from the cell body towards the dendrites or the cell bodies of the other neurons.
Answer: Large intestine
The lowest portion of the GI tract, where water and electrolytes are absorbed and waste is eliminated, is the large intestine.
Explanation:
The large intestine is the lowest portion of the gastrointestinal tract (GI), where the following occurs:
- water is absorbed
- undigested food is passed into, and watet concentrates the waste products, turning them into faeces. This faeces is finally ejected out of the body through the anus.
Thus, large intestine is the answer
The main difference would be that prokaryotic cells are thought to not have a "true nucleus", as well as only having one single floating strand of DNA/Chromatid. Eukaryotic cells have a nucleus as well as a nucleolus, and many strands of chromatid and DNA.
