Menstruation occurs when.
an unfertilized egg is expelled from the body
a fertilized egg is nonviable and is expelled from the body
a fertilized egg moves to the uterus.
the lining of the uterus is shed because an ovum has not been fertilized
The menstrual cycle is referred to as a natural transition that takes place in a female's reproductive system, due to the lining of the uterus being shed because an ovum has not been fertilized, hence option D is correct.
What is menstruation?Specifically in the uterus and ovaries, which enable conception. This cycle, which is controlled by hormonal changes, is crucial for producing oocytes and preparing the uterus to carry a fetus.
The follicular phase, ovulation, and luteal phases are the three phases that make up the menstrual cycle.
The uterus builds a wall on the uterus each month to protect and feed the fertilized egg as the body gets ready for pregnancy.
Therefore, in order to rid the uterus of any potential infections, the body will remove the accumulation in the lining when an ovum is not fertilized during monthly menstruation.

En una botella metálica tenemos un gas a 15°C y una presión de 7.5 atmósferas. Si la presión máxima que aguanta la botella es de 12.5 atm, calcular cuál es la temperatura máxima a la que se puede calentar el gas de su interior. Actividad
Answer:
207 ° C
Explanation:
De;
P1 / T1 = P2 / T2
Luego;
P1T2 = P2T1
P1 = I presión inicial = 7.5 atmósferas
T1 = temperatura inicial = 15 ° C + 273 = 288K
P2 = presión final = 12,5 atm
T2 = temperatura final =?
T2 = P2T1 / P1
T2 = 12,5 * 288 / 7,5
T2 = 480 K -273
T2 = 207 ° C

B. Because the blue color wave is being absorbed, and all the other colors are being reflected.
C. Because the blue color wave is being transmitted, and the others are not.
Answer:
A
Explanation:
because blue is being reflected, all other colors of light are being absorbed by the car.
Answer:
A: Because the blue color wave is being reflected, and all other colors are being absorbed.
Explanation:
Bright colors reflect light. Dark absorb. So white would reflect and black would absorb. Blue is bright, so it would reflect.

Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs and homozygous.
Thus, Despite the fact that fire, flooding, and other disturbances can leave a landscape in ruins, drive many animals and plants away, and bring the biological community back to an earlier stage, the habitat is still alive because the soil still contains nutrients and seeds that were sown before the disturbance.
The homozygous genotypes' two alleles are not expressed over one another in incomplete dominance; instead, an intermediate heterozygote is created.
A significant contributing factor to the variety in the traits or properties of an organism is incomplete dominance.
Thus, Where a disturbance did not completely wipe out all life and nutrients from the environment, secondary succession occurs and homozygous.

1- How could you tell whether a given sequence was DNA or mRNA?
2- Was it easier to decode messages written in DNA or in mRNA sequences?
3- Which cellular enzymes or machines are you imitating when you "transcribe" DNA into mRNA?
4- Which cellular enzymes or machines are you imitating when you "translate" mRNA into a chain of amino acids?
5- What else needs to happen in a eukaryotic cell between the processes of transcription and translation?
6- In step 5, how did different mutations affect the amino acid sequence that was encoded?
7- Explain why some single nucleotide mutations affect an amino acid sequence and some single nucleotide mutations do not.
8- Explain why nucleotide insertions and deletions affect the amino acid sequence so profoundly.
9- Why could your secret message include only 20 of the 26 letters of the alphabet?
10- Did you find that it was difficult to work with only these letters?
Answer:
DNA sequences use the nucleotides A, T, G, and C, while mRNA sequences use the nucleotides A, U, G, and C.
It was easier to decode the messages written in mRNA sequences because these sequences could be translated directly into the amino acid sequence.
The cellular enzyme that carries out transcription is RNA polymerase.
The cellular machine that carries out translation is the ribosome, which is composed of both rRNA and ribosomal proteins.
In a eukaryotic cell, an mRNA transcript often has additional untranslated regions and a poly-A tail. A eukaryotic mRNA transcript would need to be transported from the nucleus to the cytoplasm before it could be translated.
Some amino acids are encoded by several codons. If a single nucleotide mutation still encodes for the same amino acid, the resulting amino acid sequence would not be affected. This happens most often with nucleotides in the third position of a codon.
If a single nucleotide mutation changes the amino acid encoded, the resulting amino acid sequence would be affected. This happens most often with nucleotides in the first and second positions of a codon.
Nucleotide insertions and deletions cause frameshift mutations, which change the reading frame of translation and will encode completely different amino acids from that point forward.
There are only 20 canonical amino acids, so the letters B, J, O, U, X, and Z are not used as one-letter codes.
It was a little difficult to not use the letters B, J, O, U, X, and Z at first, but there are messages to write without these six letters.

What is one hypothesis to explain the diversity of life (especially the honeycreepers) on the Islands?
Isolation from parent population and random mutation caused the populations of honeycreepers to evolve and become different enough to be considered a new species.
Isolation and lots of predators played a major role in creating new species of honeycreepers
The islands started out extremely bare, so it was really hard for any mammals to get to the island.
All of the above

Isolation from parent population and random mutation caused the populations of honeycreepers to evolve and become different enough to be considered a new species.
