Article: The blade has to fit easily into the neck of the bottle. You can also try using a serrated knife so that it grips the cork better. Exercise caution when using a knife. Make sure not to cut yourself. Carefully work the knife back and forth into the cork, using very little downward pressure. It should go all the way through the cork.
Question: What is a summary of what this article is about?
Find a pocket knife or a paring knife. Insert the blade into the cork.

Problem: Article: Allow the soil in the container to dry out slightly between waterings. When the soil is dry or almost dry to the touch, it's time to water. Over-watering will cause the leaves to yellow and may result in root rot. Do not allow the plant to sit in water. Mist the fuzzy rhizomes regularly. Give them water every few days, or as needed, to prevent them from drying out. If your heat is on in your home during winter months, consider using a room humidifier where your rabbit foot fern is located. If you don't have a room humidifier, place the fern's container on a tray of wet pebbles to increase the humidity around the plant. Refill the tray as the water evaporates. The rabbit foot fern will thrive indoors in comfortable house temperatures. If the temperature drops below 60F (16C), check the plant before watering and only water when the soil is dry to the touch. If the temperature rises above 75F (24C), you may need to water the plant more often. Any liquid houseplant fertilizer can be used to feed the fern, but use only about half the recommended amount. Too much fertilizer may scorch the leaves. Do not fertilize newly potted plants for at least four to six months, or until the plant is showing signs of active growth. Thrips, mites and fungus gnats are often found on the foliage of houseplants like the rabbit foot fern. These pests like wet soil, so keep pests away by not over-watering. To remove pests, brush them off with a wet towel or a cotton swab dipped in alcohol. Most houseplant pesticides are not safe for use on ferns.
Summary: Water the fern sparingly. Grow the fern in a moderately humid environment. Maintain a 6075F (1624C) environment. Fertilize the rabbit foot fern monthly. Examine the fern regularly for pests.

INPUT ARTICLE: Article: Practice on a low beam, or even a line on the floor until you feel confident; falling from a great height can hurt badly. If you're on a high balance beam and feel like you're about to fall, just jump off, it's better to be safe then sorry when you're on a balance beam. Before you get up on a balance beam or tightrope, let your mind flow and concentrate on balancing by repeating "balance" in your head. Good concentration will lead to fewer falls. Always place a mat or something squishy under you, just in case you do fall. Pointing your toes is a wonderful way for you to not fall, because it stiffens your calf muscles as you walk on the beam.

SUMMARY: Start small. Use your arms. Concentrate. Give yourself a soft landing. Point your toes.

Each allele will fit into the two boxes below it or to the right of it, depending on its placement. For example, if the allele B is in the horizontal top-left corner, write B in the two left boxes below. If the allele B is in the vertical top left corner, you must write B in the two boxes to the right. Continue to fill in the boxes with alleles until each box has two alleles, one from each parent. The convention is to always write the capital dominant allele first followed by the lowercase recessive allele. For our hair color example two brown-haired parents could either be BB or Bb. You would have to know their specific genotype. However, if the parent is blonde you know their genotype is the recessive bb. For a monohybrid cross, there are only three possible genotypes: BB, Bb, and bb. BB (brown hair) and bb (blonde hair) are homozygous for a gene meaning that they have two identical alleles for one gene. Bb (brown hair) are heterozygous meaning that they have two different alleles for the gene. Some crosses may only give you one or two genotypes. For our example, using the cross BB x Bb, the Punnett square would show the possibilities as two BB and two Bb. If you cross two homozygous parents with the same genotype (BB x BB or bb x bb) all of the genotypes will be homozygous (BB or bb). If you cross two homozygous parents with different genotypes, BB x bb, all of the genotypes will be Bb. If you cross a heterozygous with a homozygous parent (BB x Bb or bb x Bb), you will have two homozygotes (BB or bb) and two heterozygotes (Bb). If you cross two heterozygous parents, Bb x Bb, you will have two homozygotes (1 BB and 1 bb) and two heterozygotes (Bb) Using the counts from the previous step, you can determine the phenotype ratio. A phenotype is the physical characteristic of the gene, such as hair or eye color. Assuming the trait shows complete dominance, the heterozygous genotype (the cross showing dissimilar pairs of genes for a hereditary characteristic) will display the dominant phenotype. In the BB x Bb cross, the phenotypes will be four dominant brown-haired offspring (2 BB and 2 Bb) to zero recessive blonde-haired offspring (bb) so the ratio would be 4:0. 100% of the offspring will have brown hair, but 50% of them will be homozygous while the other 50% will be heterozygous.
