Answer:

Lakes and rivers

Explanation:

Lago is the name used to designate a naturally formed depression that constantly stores a large amount of water. The water contained in a lake can have several origins, such as: own spring, rainwater, salt water from ancient seas, rivers and melting glaciers. The salt concentration in the lakes is greater than the concentration that allows the tench fish to survive. The same happens with the concentration of salt in rivers.

A river is a watercourse that flows naturally from a higher area to a lower one of the relief, usually flows into another river, lake or sea. These water courses are formed from rain, which is absorbed by the soil until it reaches impermeable areas in the subsoil where it accumulates, constituting what we call groundwater.

9. Consider the below Punnett square cross. Explain how you could use it to determine which parent

kogti [31]

Answer: The father determines the biological sex of a baby

Explanation: Human beings have two sex chromosomes, males have XY chromosomes whereas females have XX chromosomes. During fertilization, an egg from a woman fuses with a sperm cell from a man to form a zygote. Women have two X chromosomes (XX) and any point in time they can only release an egg bearing an X chromosome but males have one X and one Y chromosome, therefore they can either release a sperm cell with an X chromosome or a sperm cell with a Y chromosome. When an egg with X-chromosome fuses with a sperm cell with an X chromosome, the resulting baby is a female but when an egg with an X chromosome fuses with a sperm cell with a Y chromosome, the resulting baby is a male.

What makes the difference in both sexes is the Y chromosome from the man, therefore the father determines the biological sex of a baby.
