Answer:
The answer is "they undergo capacitation"
Explanation:
Sperm migrate through uterine contractions and the energies of its flagella to the uterine tube. In sperm motility, reverse peristalsis is engaged in the uterus and uterine tubes. For a sperm cell to fertilize an egg, it takes approximately 24 hours. The surface of the egg changes as the sperm penetrates the egg, therefore no sperm is allowed within. The kid is fully genetic, including whether it's a boy or a girl at the time of fertilization. Until they are trained it is difficult for sperm to be working.
Answer:
Sometimes molecules cannot move through the cell membrane on their own. These molecules need special transport proteins to help them move across the membrane. Facilitated diffusion is the diffusion of substances with the help of transport proteins in the plasma membrane. These special proteins are called channel proteins or carrier proteins, and they are attached to the cell membrane. In fact, they go through the cell membrane, from the inside of the cell to the outside. Facilitated diffusion is used for molecules that cannot diffuse rapidly through cell membranes on their own, even when the molecules are moving from high to low concentration areas. An example is the sugar plants and animals use for energy, called glucose. Even though facilitated diffusion involves transport proteins, it is still passive transport because the solute is moving down the concentration gradient so it does not require the use of cellular energy.
Hey this is late, but if an organ fails, like for example the kidney fails right? So then it affects the heart. and so on, because the kidney helps clean the blood and your body needs blood.
Sea levels would rise.
Increase in temperature (for example due to global warming) increases the rate of melting of polar ice.
Consequently, the sea levels of the polar ecosystem would increase.
In addition, the melting of the ice caps also increases the temperature of the water in the oceans. As a result, the water expands which also increases the sea levels.
