Irregular periods.
Hot flashes and sleep problems. Hot flashes are common during perimenopause. The intensity, length and frequency vary. Sleep problems are often due to hot flashes or night sweats, but sometimes sleep becomes unpredictable even without them
.Mood changes. Mood swings, irritability or increased risk of depression may happen during perimenopause. The cause of these symptoms may be sleep disruption associated with hot flashes. Mood changes may also be caused by factors not related to the hormonal changes of perimenopause.
Vaginal and bladder problems. When estrogen levels diminish, vaginal tissues may lose lubrication and elasticity, making intercourse painful. Low estrogen may also make vagina vulnerable to urinary or vaginal infections. Loss of tissue tone may contribute to urinary incontinence.
Decreasing fertility. As ovulation becomes irregular, the ability to conceive decreases.
Changes in sexual function. During perimenopause, sexual arousal and desire may change.
Loss of bone.
changes in cholesterol level
Here is a short explaination for you.
the moon is not really shining becuase the sun is behind it producing the light we see at night. So the moon is just a rock floating in space and when time is right the moon aligns with the sun producing what we know as moonlight.
i hope this gives an idea as to why the moon is not really shining. :)
Answer:
1 in 16
Explanation:
When two heterozygotes (AaBb x AaBb) for two autosomal genes are crossed the expected probability for the offspring is 9 A-B-, 3 A-bb, 3 aaB- and 1 aabb. In other words, out of sixteen offspring, 9 are expected to be dominant on both genes (either homozygous AA or BB or heterozygous Aa or Bb), 3 are expected to be dominant on the A gene but recessive on the b gene, 3 are expected to be recessive on the a gene but dominant on the A gene, and only 1 is expected to be recessive on both genes aabb.
Answer: Human activities is the most likely reason for it
Explanation:
A species is said to be extinct when there are no more individuals in that group, i.e, when a certain species of living beings definitively disappears from the planet. Since the emergence of the Earth, several species have disappeared and these extinctions happened for several reasons. Among the reasons, there are those caused by forces of nature such as earthquakes, volcanoes, changes in the planet's climate, such as glaciations - periods when certain parts of the planet were covered with ice, which caused the death of many beings that lived in those environments. However, in the modern society in which we live, the human being has been the biggest cause of the extinction of species.
The big problem is that the action of human beings has caused great environmental changes, altering the planet's climate, destroying habitats of several species. Human activities have a greater impact on terrestrial and freshwater ecosystems and for this reason the rate of extinction of terrestrial and freshwater species is higher than the rate of extinction of marine species
Answer:
See the answer below
Explanation:
<em>The best explanation would be that both Na and the amino acid lycine are simultaneously diffusing (in bound form) from the outside to the inside of the cell. </em>
Considering the Na alone, one would see that the concentration outside the cell decreased in equal amount (15 mM) as the increase in the intracellular concentration of the same molecule.
Also considering the amino acid alone, the extracellular concentration increased by the same magnitude (5 mM) as the decrease in the intracellular concentration of the same molecule.
<u>Hence, it could only be that both molecules bind together and diffused from the region of higher concentration (outside of the cell) to the region of lower concentration (inside).</u>
