Answer:
When the salt is added to the ice, the point of water freezing is lower, and the ice is melting.
Explanation:
The phenomenon of the salt melting the ice is called the depression of icing. The point is when we add the salt to the ice, the salt breaks water bounding molecules. This way salt is going to melt into ions and those ions are melting the ice.
In the real life, salt is also very useful, not only in chemistry. That is why people are putting salt on frozen roads, for example.
They both have a membrane and vacuole
Answer:
Explanation:
The method of reproduction in humans is sexual reproduction: a type of reproduction that occurs when new organisms are produced through the coming together of genetic information from two individuals of different sexes mostly a male and a female (egg cell and the sperm). The genetic information for making the blood cells; the red blood cells genes in particular exists on chromosomes in the nucleus of the sex cells (egg and sperm cell) also called the gametes. Basically, the DNA provides instructions for the production of mostly all of the body's needs.
The genes coding for the sickle cells which is the abnormal red cell is always inherited in the recessive form meaning both parent has to possess one copy each of the defective gene in their DNA. For humans to get one copy of a sickle cell gene and one copy normal gene; it means one of the parents gametes (be it male or female) contributed the defective chromosome and the other normal gene is contributed by the other parent during copulation giving rise to an individual that is heterozygous for the trait
For example, the sperm cell with the defective gene fertilizes the egg cell that has the normal copy of the gene producing an heterozgous individual.
An antibiotic ointment could be used for a woman's vagina lips in case of tearing in natural childbirth which can happen if the baby is say a little too large for the opening as long as not too large to require a caesarian.
During meiosis when the spindle fibers pull apart the chromosomes this happens at radon so there are different variations of genes being pulled apart
