Comparative embryology is the branch of embryology that compares and contrasts embryos of different species. It is used to show how all animals are related.
Answer:
The answer is spongy mesophyll.
Explanation:
Between the upper and lower epidermis of a leave, you can find the so called mesophyll tissue which is rich in chloroplasts. There are two types of mesophyll tissue: the palisade and the spongy mesophyll. Whereas the cells of the palisade mesophyll are tightly packed, the cells of the spongy mesophyll are loosely packed.
Answer:
A protein that is destined to be secreted from the cell:
- is targeted to the RER as a soluble protein.
Explanation:
The main function of the RER is the synthesis and transport of secretion or membrane proteins.
If you are looking for the RER you could fount it on eukaryotic cells, side by side of the nucleus, and cover in ribosomes.
Answer:
The electrical signal will not be converted into chemical signal.
Explanation:
The synaptic knob is the bulbous enlargement also called synaptic terminal preset at the end of the axon.
The synaptic knob is a living cell and thus contains all the living features but they also contain the vesicles which store the neurotransmitters, therefore, synaptic knob acts as a site which converts the electrical signal into a chemical signal. The released neurotransmitter from the synaptic knob interacts with the post neuron or recipient neuron.
If the mutation develops in the neurons which result in the formation of neurons without synaptic knob therefore the electrical signal will not be converted into a chemical signal and thus signal will stop.
Answer:
The phosphorus in all biological tissues can be traced back to phosphorus weathered from rock.
