If you combined these eggs with normal sperm, you would expect to see lower fertilization rates and lower embryonic development rates.
The vitelline envelope is a membrane that surrounds the egg and provides nutrients and protection. If the envelope is too dense, it will be more difficult for sperm to penetrate and fertilize the egg. Additionally, the embryo may have difficulty developing properly if the envelope is too dense.
The dense vitelline envelope would make it more difficult for the sperm to penetrate the egg and fertilize it. Even if fertilization did occur, the dense vitelline envelope would make it more difficult for the embryo to develop and survive.

When you drink too much water and get water intoxication why would doctors give you a sodium IV solution? (explain scientifically)
Answer:
Let me attempt to answer your question
Drinking too much water would mean that more water would be absorbed and end up in the intracellular compartment. The chief ion extracellularly is Sodium,which is "water-loving"
The doctors give a sodium IV solution (hypertonic) so that there would be more sodium extracellularly to extract water from the intracellular compartment from where water can be more easily excreted.

What is a dihybrid cross?The two features of two people regulated by two different genes are called a dihybrid cross. A dihybrid cross is made up of two people who have two features that are regulated by two different genes. Gregor Mendel's observation of pea plants that were either round or wrinkled, yellow or green, gave rise to the concept of a dihybrid cross. When On the cross of two heterozygous people we can predict the genotypic and phenotypic ratios of the offspring’s . Crossing heterozygous parents would result in an estimated phenotypic ratio of 9:3:3:1, meaning that 9/16 of the individuals have the dominant phenotype for both traits, 3/16 have the dominant phenotype for one trait, 3/16 have the dominant phenotype for the other trait, and 1/16 have the recessive phenotype for both traits,Only applies to sexually reproducing organisms like angiosperms. The components of the predicted phenotypic ratio of 9:3:3:1 are as follows:
The number 9 denotes the percentage of people who exhibit both dominant traits: 1 RRYY, 2 RRYY, 2 RrYY, and 4 RRYY The first three people are those who exhibit the first dominant trait and the second recessive trait, respectively: 1 RRyy plus 2 RRyythe second three are those who exhibit both the first dominant and second recessive traits: 1xrrYY plus 2xrrYyThe homozygote, represented by the number 1, exhibits both recessive traits: 1 x rryyIn the illustration on the right, heterozygous F1 offspring for both R and Y are produced by the RRYY/rryy parents (RrYy).

If it is desired to decrease the volume of the gas sample to 6.23 L, while increasing its pressure to 0.647 atm, the temperature of the gas sample at the new volume and pressure must be
The temperature of the gas sample at the new volume and pressure must be 65.74 T
What do you mean by volume and pressure?
Pressure is force (in newtons, N) divided by the area ( in square meters, m2 ) over which it acts (P = F/A). Volume is the amount of space is taken up by an object or, in our case, a parcel of gas.
The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law). Under the same conditions of temperature and pressure, equal volumes of all gases contain the same number of molecules (Avogadro's law).
Hence, for a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant.

A cell containing 12 replicated chromosomes at the beginning of mitosis will have how many chromosomes after the completion of mitosis?.
Cell containing 12 replicated chromosomes in beginning of mitosis. There are 12 chromosomes after the completion of mitosis.
What is Mitosis?Two genetically identical daughter cells are created during mitosis, along with the original cell. A diploid cell has 2X DNA and 2N chromosomes at birth. The cells are still genetically diploid (2N chromosomal number) after DNA replication, but they contain 4X as much DNA because each chromosome has done so. A united pair of identical sister chromatids make up each chromosome today. Two identical cells with 2N chromosomes and 2X DNA each emerge from mitosis.
Chromosomes condense during prophase; each chromosome is made up of two identical sister chromatids that are linked at the centromere.In the metaphase, the spindle apparatus' microtubules push and tug the chromosomes into alignment along the plane of cell division in the center of the cell.Chromatids start to decondense and congregate at the opposing ends of the cell during telophase.The membrane pinches in during cytokinesis to split the two daughter cells.To know more about mitosis, visit:

Small hydrophobic molecules and gases such as oxygen and carbon dioxide pass quickly through the membrane. Small polar molecules like water and ethanol can also pass through the membrane, but more slowly.
A conformational change in the channel moves the second-site potassium ion away from the protein.
