The human reproductive system is different in males and females. When a sperm and egg join, the egg is fertilised and a baby starts to develop. Its mother provides all a baby’s needs until it is born.Fertilisation happens when an egg cell meets with a sperm cell and joins with it. The fertilised egg divides to form a ball of cells called an embryo. The embryo attaches to the lining of the uterus. It begins to develop into a fetus and finally into a baby.The mother’s lifestyle can affect the developing fetus. For example, smoking reduces the amount of oxygen in the bloodstream. This can lead to low birth weight and premature birth (when a baby is born too soon). Drinking alcohol during pregnancy can harm the developing baby’s nervous system, especially its brain.

Birth

It takes about 40 weeks for a baby to develop in the uterus. This time is called gestation. After this, the baby is ready to be born. The cervix relaxes and muscles in the wall of the uterus contract. Waves of muscle contraction push the baby out of the mother's body through the vagina.

How does biodiversity support healthy ecosystems
pav-90 [236]

ANSWER: Biological biodiversity refers to all the different kinds of life that are obtainable in a particular ecosystem, this include all the plants and animal populations that are found in a particular geographical area.

Biodiversity supports healthy ecosystem because it enhances the productivity and the survival of the ecosystem. For instance, in a situation where there are large number of different plant population in an ecosystem, such population will present variability in genetic make up. If a negative event occur in the ecosystem, it will be possible for some plants to survive. But, in a situation where it is only one type of plant that is obtainable in the ecosystem, it will be quite easy to wipe all of them out at once. For instance, a disease outbreak can easily destroy all the plants.

Drinking too much water during exercise can cause a condition in which the concentration of sodium in the blood is lower than no
OlgaM077 [116]

The right answer is Cells shrivel as water moves out of them.

Water intoxication (hyperhydration) occurs when too much water consumption causes a decrease in the concentration of electrolytes in the blood, partly because the electrolytes are eliminated in excessive amounts, on the other hand by increasing blood volume without sufficient electrolytes. When the intercellular (extracellular) medium is too diluted relative to the intracellular medium, the osmotic pressure induced by this difference can cause the cells concerned to explode (the cell wall ruptures under pressure), in the first place the nerve cells, which causes disorders brain that can be severe or even fatal.
