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.
Answer: Uses glucose ;produces carbon dioxide
Explanation:
Cellular respiration can be defined as the process by which the chemical energy in the body is transferred into ATP and some of it is released in the form of heat.
During this process the glucose that is broken down and the energy released is converted into ATP.
Carbon dioxide is released as a by-product of this process.
Hence, the correct answer is option C and D
Answer:
The most interesting thing about DNA is all the information that is found in these very small molecules, capable of directing how will be the physical aspect and all the functions of a living being.
Explanation:
Deoxyribonucleic acid or DNA is a macromolecule that contains all the genetic information of living beings, directing the synthesis of compounds that determine their physical appearance and functions.
The most interesting aspect of DNA is that it is a molecule —with a tiny size compared to the size of an organism— that is found inside the nucleus of a cell and whose information defines the complete life of individuals.
A DNA molecule forms a chromosome, which contains genes that determine specific traits. Genes are also fragments of the DNA in the chromosome they form, whose specific sequence is translated into characteristics expressed in the phenotype.
A molecule as small as DNA contains a great deal of information. The human genome, for example, contains about 3,200,000,000 base pairs, information that could be transcribed into 3,000 textbooks.
It is the Hypertonic Side. Osmosis applies a weight known as osmotic weight on the hypertonic side of a specifically porous film.
This implies osmotic weight should deliver a net development of water into a run of the mill cell that is encompassed by new water. On the off chance that that happens, the volume of a cell will increment until the point when the cell ends up plainly swollen. In the end, the cell may blast like an overinflated expand.
Answer:
protists
Many diverse organisms including algae, amoebas, ciliates (such as paramecium) fit the general moniker of protist. "The simplest definition is that protists are all the eukaryotic organisms that are not animals, plants or fungi," said Alastair Simpson, a professor in the department of biology at Dalhousie University.
