Cell Membrane Semi-permeable membrane made of phospholipids that acts as a barrier between inside and outside of the cell.
Cytoplasm The fluid, cytoskeleton, and organelles inside a cell.
Nucleus Contains DNA and control's the cell's activity.
1. Passage of a sperm through the corona radiata of the oocyte.
2. Penetration of the zona pellucida.
3.Fusion of the plasma cell membranes of the oocyte and sperm. after fusion the sperm head and tail enters the oocyte but plasma membrane of sperm doesn't.
4. Completion of the second meiotic division of the oocyte. this creates female pronucleus and polar body 2.
5. Formation of the male pronucleus (nucleus of sperm enlarges)
6. Breakdown of the pronuclear membranes and restoration of diploid number of chromosomes.
You could also say that the neutron is the odd man out because the number of protons and electrons are the same because the negative charge from the electronics attracted to the positive charge from the proton.
On the next line you could say the election is the odd man out because the protons and neutrons reside in the nucleus and the electrons fly at high speeds in the electron cloud.
To begin, you have to know what meiosis is. Meiosis is when a cell breaks into four daughter cells (like mitosis but with two extra daughter cells). Those four cells are still part of the parent cell, so they retain the genetics of the parent cell but split-up. So those cells are part of the foundations of the genetic build-up of the offspring.
Answer:
The correct answer is paired sample t-test.
Explanation:
Based on the given information, the mothers living in poverty in the United States give birth to underweight babies. The average weight of the babies given birth by women living in poverty is 2.8 kg. To examine the efficacy of a novel prenatal care program, a test was conducted by the CDC in which 30 mothers living in poverty and the weights of their babies were recorded.
As the test is conducted in pairs, thus, paired sample t-test would be the appropriate hypothesis test. The paired t-test is performed when the dependent variable is measure spontaneously. In the given case, the women participating in the program and the number of babies with less birth weight are examined in pairs. Thus, as the sample are paired together, the correct answer would be paired sample t-test.
