These stem cells come from<span> embryos that are three to five days old.

The correct answer is Morton's Neuroma.
This is a condition which affects the nerves between your toes, and causes you to feel as if you were 'walking on a marble.' You feel constant pain in the ball of your foot which can be helped relatively easy if you change your footwear.
1. <span>The most likely explanation for this difference in height is a difference in nutrition because rich families have a better lifestyle than poor families.
2. The disease must be recessive because there is a window diagram of people who inherit the genetic disease.
3. </span>A farmer chooses the cows in his or her herd that produce the most milk and breeds only those cows. The explanation in this is the group of cows that produce the most milk are probably the ones who have the link of family lineage between them. Breeding of healthy cows produces also healthy cows thus healthy cows will be breed to each other.
4. I<span>ncreasing the amount of crop harvested should be the advantage of the farmer. Increase of the amount of crop harvested means increase of the farmer's income.
5. </span><span>D. Blastocyst > zygote > embryo > fetus. Blastocysts are structures that formed early in day 5 of in-vitro fertilization process which will be transformed later into zygote. The zygote will undergo in a division process called mitosis and after the first eight weeks of fertilization, embryo will be formed. Bodily or organ structures will then appear and after this development by twelfth week of fertilization, fetus will be formed and this will be the last stage of development that includes growth.
6. </span><span>The new cell that is formed from fertilization is called zygote. This eukaryotic cell is produced from joining of two gametes together.
7. </span>Egg-laying land animals have evolved to produce eggs with tough shells to ensure that <span>external fertilization can take place with caution and safety. Tough shells are needed to protect the cell that undergoes fertilization.
8. Plants and animals reproduce in different ways but they both </span><span>carry hereditary material from parent. Genes from their origins are carried and the appearance of some trait will be shown by the offspring.
9. There is a 50% that the second offspring will be a girl. It really depends on the genetic material and biological character of the mother and there are factors that needs to be checked </span>upon giving birth.
10. <span> One of the plants has the nutrients and light it needs to grow and flower, while the other does not. The environment is similar between the two plants but the manner or means of taking care of it depends on the people who own it. This also affect the access of the pollinator to the flower if a flower does not have any nutrients to give.
11. </span> Over time, a plant pollinated by a hummingbird has developed very long, tube-like flowers. <span>The longer, tube-shaped flowers probably developed to keep the hummingbird from reaching and drinking the flower’s nectar. Birds are creatures who flies high and the for them to reach the flower's nectar, the plant should also be high.
12. </span><span>Pollen inside the cherries fertilizes ovules, which produce seeds. This helps to reproduce the plant of cherry trees because seeds are the source and without seeds there would be no plants or trees to grow.
14. A</span><span> plant that reproduces with flowers is called angiosperm with a scientific name of magnoliophyta, subkingdom of embryophyta.
15. </span><span>At certain times of the year, the male sage grouse can be seen inflating the air sacs on his chest and singing loudly to a female sage grouse. This behavior is likely an example of a courtship ritual practiced or acted by the nature of male animals. The male animal are would try to impress the female animal by showing off their talent or giving them anything to offer for an intercourse.
16. </span><span>In humans, the developing embryo receives nutrients and oxygen through a tube called the umbilical cord. This tube is connected between a mother and a fetus inside the mother's body. The nutrients received by the mother will also be received by the neonate by means of infusion or absorption through the barrier.</span>
Answer:
E (All blood types are possible)
Explanation:
The ABO blood group system in humans is a vivid example of co-dominance, where blood type A and B are codominant but are both dominant over blood type O.
Based on this genetic scenario, A codominant blood type AB can be produced, Blood type A can possess AA and AO, Blood type B can possess BB and BO, while Blood type O can only possess OO.
Hence, in a cross between a type A individual- AO or AA and a type B individual- BO and BB, gametes will be produced according to Mendel's law of segregation.
AO, AA (Type A) = A and O gametes.
BO, BB (Type B)= B and O gametes.
Hence, from the combination of these gametes, their offsprings can possess AB, AO, BO, OO which covers all the blood types.
Therefore, all blood types are possible
Cells need to be small in order to make exchanging materials faster. This is because, as the size of the cell increases (if we were to increase the size), then the volume increases faster than the surface area. We want more surface area, so this isn't effective if we increase the size. The larger the size also means that it takes more energy for them to move, so there will need to be more cytoplasm, and that's too much effort to generate. Imagine being in math class when you use those cubes, the one huge cube assembles 100 small cubes, that one huge cube has less surface area than those 100 small cubes combined. That's why we need small cells. A larger surface area allows for more exchanges to occur and a larger volume allows for more materials to be brought in or released from the cell at a given time. (The rate of exchange would increase for larger surface areas and volumes of cells.)
