Answer:
5. All magnesium atoms have the same number of neutrons
Explanation:
Magnesium (Mg) is a chemical element. Its atomic number (Z) is 12 (number of protons in the nucleus of the Mg atom).
The Magnesium has three stable isotopes: 24Mg, 25Mg and 26Mg. All these isoforms have 12 protons in their atoms (same atomic number), however they vary in the mass number of the atom (M).
The mass number of the atom (M) is equal to the sum of protons and neutrons in the nucleus.
Based on this information we can know how many neutrons each isotope has
24 Mg = 12 protones + 12 neutrons
25Mg = 12 protones + 13 neutrons
26Mg = 12 protones + 14 neutrons
In this way we conclude that <u>not all magnesium atoms have the same number of neutrons</u>
The symptoms given may be a manifestation of Polycystic
Ovary Syndrome (PCOS), which is a common endocrine system disease among
females.
Symptoms are the following:
<span>1. </span>Menstrual disorders: oligomenorrhea (irregular
period) or amenorrhea (cessation of period), which start around the time of the
first period (menarche)
<span>2. </span>Infertility: which results from anovulation
(ovaries are unable to release an egg cell during ovulation)
<span>3. </span>Obesity: at least 40% of females with PCOS are
obese
<span>4. </span>Hirsutism (excessive body hair where hair is usually
minimal or absent): big amount of
masculinizing hormones in women with PCOS may cause hirsutism

Answer:
r-selected species (e.g., American bullfrog)
Explanation:
The r-selected species (r-strategists) are those species in which their populations oscillate near the carrying capacity, i.e., the maximum population size sustained by a particular environment. These species are generally located in low-quality (less competitive) ecological niches and produce many offsprings that grow rapidly and have low chances of surviving to adulthood. Some examples of r-strategists include amphibians, fish, small mammals, etc. Conversely, K-selected species have more stable populations and produce a low amount of offspring (e.g., large mammals such as elephants).
