When a man has an erection does he releases sperm​

Biology
1 answer:
Nastasia [14]3 years ago
8 0

Answer:

Not necessarily.

Explanation:

An erection is caused by blood flow to the penis. A man can get an erection just by seeing a woman or hearing language that turns him on or excites him. A young man who is not experienced in controlling an erection may release sperm in a spontaneous ejaculation but more experienced men would not likely ejaculate without more stimulation, such as masturbation.

What type of solvent would dissolve a nonpolar solute
attashe74 [19]

Answer:

Explanation:

For example, ionic compounds, which are very polar, are often soluble in the polar solvent water. Nonpolar substances are likely to dissolve in nonpolar solvents. For example, nonpolar molecular substances are likely to dissolve in hexane, a common nonpolar solvent.

All cells as we can say they work through their proteins. The work of proteins is being characterized by their sub-atomic capacity, contribution to a specific natural process and limitation inside. Segments of protein work which are being characterized by the correct synthesis, adaptation of proteins and structure which are being scrambled in the DNA area which is another name is called locus encoding the protein.
New proteins are being produced by the procedure of protein combined with organic cells, which are adjusted by the loss of protein cell through corruption. The RNA which is duplicated in protein hereditary data is encoded in DNA atom which is being created in the core known as RNA or mRNA. mRNA encodes data which is for solitary protein and is considered little in estimate by contrasted with DNA atom. This makes work easier for mRNA particles to leave the core passing through some small openings called atomic pores.
It leaves the core and goes straight to the cytoplasm. mRNA interferes with cell structure referred to as ribosome and fills in as cells contrasting agent within the procedure of protein union. Ribosome comprises of ribosome RNA particles or rRNA and proteins which are sorted out into two subunits.
When a small subunit is being accused of tRNA and corrosive amino acid methionine experiences mRNA which begins to begin flag.
When beginning succession AUG is found then the codon for corrosive amino methionine where substantial subunits join the little one to frame and hole ribosome where now protein amalgamation starts.
Following the codon downstream of AUG codon, the elongation of tRNA and amino corrosive enter to the ribosome. tRNA with wrong amino corrosive and wrong anticodon enters ribosome it is rejected because it can not base pair with mRNA.
The ribosome then propels on triplet and amino corrosive and tRNA enters the ribosome and method is then rehashed. In the termination, the ribosome achieves all the stop codons. Post-translation modification alludes to the covalent and leads to large enzymes change of proteins following biosynthesis of protein PTM happens in any progression within the life cycle of protein.
Protein in PTMs can be reversed depending upon the idea of change for example kinases phosphorylate of protein at a certain amino corrosive side chains phosphatases hydrolyzes phosphate where they gather and expel it from protein.

The first stage of neural communication, _____, is the movement of the signal within a single neuron. _____ is the movement of a
9966 [12]

Answer:

The first stage of neural communication, <u>conduction</u>, is the movement of the signal within a single neuron. <u>Transmission</u> is the movement of a signal between neurons.

Explanation:

The neuron is the irreplaceable and highly specialized unit of the Nervous System, since it is the basic element in the conduction of the nerve impulse. The primary function of the neuron, conceived in its uniqueness, is to receive information and transmit it, once it has been processed.

The nerve impulse only spreads in one direction. When a neuron is stimulated, electrical changes originate that begin in the dendrites, pass through the neuronal body, and end in the axon, this is known as conduction. At the point where an axon and a dendrite are associated, it plays a very important role in the transmission of the impulse from one neuron to another and in the functioning and coordination of the nervous system in general, since the neurons do not act in isolation. The neurons are arranged in such a way that the axon endings of one are connected with the dendrites of the next neuron, but there is no physical contact itself, but a microscopic space that separates them, in addition there is a neurotransmitter substance that allows the flow of nerve impulse under those conditions, said substance is acetylcholine. These transmitting molecules diffuse through the synaptic cleft and chemically transfer the signal, from the axon of a neuron to the receptor neuron.
