A preganglionic sympathetic fiber traveling to the abdomen would synapse in which structures?
juin [17]

Answer:

Answered below.

Explanation:

The nerve fibres of the autonomic nervous system that connects the ganglia to the the central nervous system are called preganglionic fibres. They are divided into sympathetic preganglionic fibres and parasympathetic preganglionic fibres and both have acetylcholine as their neurotransmitter.

The sympathetic preganglionic is shorter compared to the parasympathetic preganglionic fibres. They originate from the hypothalamus and brainstem and project to the ganglia non the spinal cord. A ganglion is a cluster of nerves outside the central nervous system.

The preganglionic sympathetic fibres originating from T1-T2 innervate the cervical ganglion which innervates the muscles of the pupils (dilators).

The postganglionic fibres originating from the preganglionic fibres of T11-L3 passes through splenic, celiac and mesenteric ganglia to innervate the kidneys and renal vessels.

A tree that has leaves that are shaped to help water drip off them would most likely live where?
Elena-2011 [213]

Answer:

The correct answer is tropical rain forests.

Explanation:

The hot and moist biome witnessed close to the equator of the Earth is the tropical rainforest. The largest tropical rainforests in the world are found in Africa, South America, and Southeast Asia. About 60 to 160 inches of rainfall is witnessed in the tropical rainforests throughout the year. Due to this, the leaves of the trees found in the tropical rainforests possess unique features that help them to survive.  

The leaves of the trees found in the tropical rainforest possess drip tips that help them to cope with the extreme amount of rainfall that takes place throughout the year. The drip tips help the drop of rains to run off briskly from the surface of the leaves. This adaptation helps the plants in the region to prevent the growth of bacteria and fungus.

Drag each label to the correct location on the diagram.
algol13

Diagram found elsewhere attached

Answer:

Clockwise from bottom

3. formation of mRNA in the nucleus

6. secretion of hormone  by tissue

4. initiation of DNA  replication because  of a signal given  by the hormone

2. synthesis of protein  molecule by mRNA  and tRNA

1. secretion of protein  by the cell

5. binding of the  hormone molecule  with its receptor  of the cell

Explanation:

The tissue in the top left releases a hormone. For example, a steroid hormone such as estrogen, which can impact gene expression at the level of transcription. This hormone then travels to a different cell to carry out its function. The hormone is able to enter the cell and binds receptors which recognise it. In this case, these receptors are present in the nuclear envelope. When the hormone has bound the receptor, it initiates a signalling cascade that the cell responds to.

In this case, the effect of the signal from the hormone is to initiate DNA replication. This is a common effect of hormones such as growth factors that signal the cells to proliferate.

The initiation of the signalling can  also affect how genes are expressed. In this case, an mRNA is produced in the nucleus, which is created as a result of transcription. This mRNA molecule then moves to the cytoplasm, where it becomes translated into a polypeptide sequence at a ribosome, with the help from transfer RNAs (tRNAs).

This polypeptide forms a mature protein by progressive folding and potential modifications, and is released by the cell to perform its functions.
