A galaxy is a group of stars, interstellar gas, dust, etc.
There are different types of galaxies. They are all categorized by their shape:
Spiral: a spiral galaxy has a disc in the centre and curved arms that come out of it.
Irregular: it does not have a specific shape. It is just a mass of things.
Elliptical: an elliptical galaxy looks basically like a disc in the universe.
I hope it helps. I tried to explain it as easy and as simple as possible!
Answer:
it best illustrates mutualism which is defined as a relationship that benefits two organisms, or it is defined as a doctrine in sociology where mutual aid is beneficial to society and the individual. An example of mutualism is pollination which is when bees take nectar from flowers and then deposit the nectar on another flower. I hope dis helps :3
Answer:The mother's antibodies can destroy the red blood cells of the fetus.
Explanation:
If a woman with an Rh negative (Rh-) blood group has a child with an Rh positive (Rh +) male, there is a possibility that the child is also Rh +. Although this has no consequences throughout pregnancy itself, as the mother's and fetus's blood does not come into direct contact during pregnancy, it can have serious consequences for subsequent pregnancies.
In fact, rupture of the placenta at the time of childbirth may allow some red blood cells from the fetus to pass into the maternal circulation and cause sensitization, meaning the woman's body will detect them and begin to make anti-human antibodies. Rh that will persist indefinitely in the blood. If a woman regenerates another Rh + child, the anti-Rh antibodies present in her blood will pass easily into the fetus's blood through the placenta and attack and destroy the fetus' red blood cells, which can lead to severe fetal anemia and serious repercussions that sometimes lead to intrauterine death.
Answer:
The Restriction Fragment Length Polymorphism (RFLP) and the Polymerase Chain Reaction (PCR) are techniques used in molecular biology to identify polymorphisms in DNA samples obtained from different species, organisms, varieties, strains, etc. In the case of RFLP, the DNA is digested with restriction enzymes, so the resulting fragments have different lengths, while in the PCR technique the DNA fragments are obtained by successive amplification cycles and they have the same length.
No they are not the same because the velocity of a compound reacts differently to an element causing an up stir. The correct statement is The properties of a compound have a higher rate of joules causing a difference between elements
