PLEASE HELPPPPP!!!!! The law of conservation of mass states that the mass of all the substances present before a chemical change equals the mass of all the substances remaining after the change. Design an experiment to verify this law.

Answers

Answer 1

Answer:

Use the vingear and baking soda experiment but change it to lemon and not vingear.

Explanation:

A chemical reaction takes place when vinegar and baking soda are mixed. One of the new substances formed is carbon dioxide gas. If the carbon dioxide gas is contained, the mass of the substances will stay the same according to the Law of Conservation of Mass. If the gas is allowed to escape, the mass will be less

In the female human reproductive system, eggs are created in an ovary, and implanted in the uterus. For the embryo to grow, it must receive nutrients and oxygen. This problem is solved through an organ called the A. Amniotic sac B. Placenta C. Uterus D. Umbilical cord

Answers

Answer:

The correct answer is D. Umbilical cord

Explanation:

The umbilical cord connects the fetus to the placenta and through it exchanges nutritional substances as well as oxygen-rich blood. The umbilical cord is maintained throughout gestation until the moment of birth, when it is cut and leaves a permanent scar, the navel. The umbilical cord is responsible for breathing and feeding the fetus until the moment it is born, so any failure or blockage in the circulation of oxygen and nutrients through the cord can lead to injury or even death of the embryo. It also serves to remove waste and carbon dioxide (CO2).

Usually it is a secreted protein or a steroid hormone. ... Examples are cytokines and hormones that bind to specific receptors on the surface of their target cells.

2. what helps cells grow? For a typical dividing mammalian cell, growth occurs in the G1 phase of the cell cycle and is tightly coordinated with S-phase (DNA synthesis) and M phase (mitosis).

Explanation:

Once we are grown up, many cells mature and become specialised for their particular job in the body and they don't reproduce so often. But some cells, such as skin cells or blood cells are constantly dividing. When cells become damaged in any way or die, the body produces new cells to replace them. This process is called cell division.
