<span>overall, around twenty million teenagers contract an STI (sexually transmitted infection) each year. </span>(The half of them are from U.S.)<span>
A sexually transmitted infection (STI) is an infection that is transmitted between partners during different forms of sexual intercourse. This infection can lead to an infectious disease, formerly called venereal disease (the name comes from Venus, goddess of love)All sexual practices that involve mutual genital or oro-genital contact with another person, or genital fluids, are considered to carry a risk of transmitting an STI. Each STI has a different risk and severity.

During forced <span>exhalation</span>, as when blowing out a candle, expiratory muscles including the abdominal muscles and internal intercostal muscles generate abdominal and thoracic pressure, which forces air out of the lungs.

Most prokaryotes with circular genome do not have telomeres.
Answer:
The correct answer is 0.26 M
Explanation:
The initial concentration of NaCl solution (Ci) is 5.0 M. The initial volume of the solution (Vi) is 13 mL. The final volume is the addition of 240 mL to 13 mL (Vf= 13 mL + 240 mL= 253 mL).
In order to calculate the final concentration of the solution (Cf) we can use the following expression:
Ci x Vi= Cf x Vf
This mathematical expression is often used to calculate concentrations in dilution procedures. So, we introduce Ci, Vi an Vf in the expression and we calculate Cf:
Cf= (Ci x Vi)/Vf= (5.0 M x 13 mL)/253 mL= 0.257 M ≅ 0.26 M
The answer is ATP production glycolysis, Krebs cycle, and electron transport aerobic in that order. Glycolysis occurs in the cytoplasm while the other two stages occur in the mitochondria (Krebs cycle in the mitochondrial matrix and the electron transport chain in the mitochondria membrane).
The answer is Autotrophs. Examples of autotrophs are plants and photosynthetic bacteria (photoautotrophs). They convert abiotic factors such as light to organic molecules. These also include chemosynthetic bacteria (chemoautotrophs) that elements such as sulfur dioxide and methane in hydrothermal vents to organic molecules.
