This phenomenon might increase sperm production in males
Explanation:
The most common androgen is testosterone, a hormone produced in the animal male gonads.
In the male gonads, testosterone binds to androgen receptors to activate transcription of genes involved in spermatogenesis
Answer:
C Halobacterium species
Explanation:
ThIs is because this species of bacteria thrive well in high salt concentrations; and will be inactive in a low salt concentration medium.They are known as Hallophilic Organisms. (salt organism)s
They are rod-shaped, motile organisms , which reproduced by binary fission,live in saline lakes, with the cell bounded by a single layer of plasma membranes.They contain beta-caroteen pigments. it is this that is responsible for their red coloration.When this pigment is extracted, is used in food dye. giving food red coloration.
In addition, Halo. Bacteria contain some enzymes that can break dowm organic molecules to simplest forms. These are Degredative enzymes.(e.g Lipase , Amylases). it is this feature that aids their application for aiding the process of fermentatio<u>n of salty foods</u>, and also aiding of <u>coffee processing during production. </u>
<u>Since this is called a salty bacterium, and its enzymes will be most active in high salty concentrations, then option C is the correct answer.</u>
Answer: Dendrites are projections of a neuron (nerve cell) that receive signals (information) from other neurons. The transfer of information from one neuron to another is achieved through chemical signals and electric impulses, that is, electrochemical signals.
