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.
I am not 100% sure but I think it’s A sorry if I am wrong but a answer is batter then no answer lol have a good day
Answer:
a. derivatives of triacylglycerols that contain a polar phosphate head and an amino alcohol at one of the positions of the glycerol group.
Explanation:
Glycerophospholipids consist of glycerophosphate which is an ester of glycerol and phosphoric acid, long-chain fatty acids, and certain alcohols. The glycerophospholipids is responsible for the formation of cellular membranes of organelles within cells of all organisms. The name of Glycerophospholipids indicates the presence of glycerol, phosphorus and lipids so that's why we can say that it is derivatives of triacylglycerol that contain phosphate and an amino alcohol at one of the positions of the glycerol group.
Answer:
It limits the spread of pathogens
Explanation:
Many diseases are contracted byu direct contact with an individual that is a carrier of a disease. The pathogens primarily spread by direct contact includes parasites, certain bacteria, certain viruses. For example, viruses include: Hepatitis A and Hepatitis E and are associated with poor sanitation and hygiene, leading to infection and inflammation of the liver.
Answer:
The collisions release heat, which results in the heating and subsequent melting, sinking, and rising of materials.
Explanation:
The collisions literally release heat (kinetic energy). Energy from collision increased temperature, causing materials to melt.
