Gram-negative cells stain purple whereas, Gram-positive cells stain pink or red when using the Gram stain technique,
Gram-positive bacteria cells are able to retain the color of crystal violet dye due to the presence of thick peptidoglycan in their cell walls.
Gram-negative bacteria cells are not able to retain the color of crystal violet dye in their cell walls due to the thinness of the cell wall. Hence, they could not retain the color of the primary stain. Instead, they are counter-stained by safranin.

Answer:
Plastic wrap is commonly made out of PVC (Polyvinylidene Chloride). In recent years other PVC alternatives have become more popular. The most popular option in recent years is LDPE (Low-Density Polyethylene) because it is considered to be safer for the body. The best management for plastic wrap would have to be by you taking plastic wrap to local retail stores where they collect plastic grocery bags for recycling. Any package that you see with the How2Recycle Store Drop-Off label can be recycled this way.
Human waste from excretion is probably classified as organic waste, since it comes from you and the food you eat. The best management for human excretion would probably be sewer pipes that lead into the sewage system that lead into other mainframes.
Wastewater is an odd typing since it contains human waste, food scraps, oils, soaps and chemicals. The best management for this would include physical water treatment, biological water treatment, chemical treatment, and sludge treatment.

- If a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be?
Answer:
If 0.9% NaCl were isotonic to a cell then anything greater than 0.9% would be hypertonic. A hypertonic solution is one which has a greater concentration of dissolved solutes while an isotonic one has a similar concentration of solutes.
Explanation:
If a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be 1.0%. Thus, the correct option for this question is D.
What is a Hypertonic solution?A hypertonic solution may be defined as a type of solution that significantly has lower osmotic pressure than another solution to which it is compared. If the surrounding solution has a higher solute concentration compared to inside the cell, it represents a hypertonic solution.
According to the context of this question, if a 0.9 % salt solution is isotonic to an animal cell, then anything greater than 0.9% would be hypertonic. So, all the options except for 1.0% are lesser than or equal to 0.9%.
Therefore, if a 0.9 % salt solution is isotonic to an animal cell, then a hypertonic solution would be 1.0%. Thus, the correct option for this question is D.

Describe the behavior of the chromosomes in then second division of meiosis.
Answer:
The typical behavior of chromosomes in meiosis is that homologous pairs synapse, recombine, and then separate at anaphase I. At anaphase II, sister chromatids separate. However, studies of small chromosomes in maize derived from a variety of sources typically have failure of sister chromatid cohesion at anaphase I. This failure occurs whether there is pairing of two copies of a minichromosome or not. These characteristics have implications for managing the transmission of the first generation artificial chromosomes in plants. Procedures to address these issues of minichromosomes are discussed.
Normal chromosomes enter into meiosis following DNA replication. The homologous pairs find each other in the process of synapsis. Recombination exchanges parts of the homologs involving two of the four chromatids present. Then in anaphase I, each member of the pair segregates to opposite poles and into the two cells resulting from meiosis I. In contrast to mitosis, the sister chromatids of each homolog remain attached to each other. At meiosis II the sisters now separate to opposite poles. The consequence of this sequence of events is that segregation of genetic markers on the two members of the pairs of homologs enter into different gametes that will eventually be formed after meiosis. However, small chromosomes as observed in maize do not follow these rules. In this review, we describe the information known about these minichromosomes and what they inform us about meiotic processes. Also, the behavior of small chromosomes impacts how engineered minichromosomes will behave and so information about them is important for practical applications as well.

Red-green colorblindness is caused by a mutation in a gene on the X-chromosome. Bob (dad) has red-green colorblindness. Karen (mom) has color vision. Bob and Karen have a biological child named Taylor, who does not have red-green colorblindness. Taylor marries someone who has red-green colorblindness and they have 2 boys and 8 girls. Both boys have red-green colorblindness while all their sisters have color vision. Taylor is most likely:
Answer:
A carrier of red-green colorblindness?
Explanation:
This means she has one mutated X chromosome and one regular X chromosome. They cancel each other out because one is regular and one is mutated. But that one mutated X chromosome paired with the fathers mutated Y chromosome making both of the sons have red-green colorblindness.
A recent diet trend has made snack cakes far less popular than they once were. As such, demand for snack cakes is expected to
fall. As demand falls, (1 point)
o producers make lower profits, and some will exit the market
O consumers face lower prices, and are encouraged to consume more
O consumers face higher prices, and are encouraged to consume less
O producers make higher profits, and more will enter the market
Producers make lower profits, and some will exit the market. The correct option is A.
Thus, Reduced demand for snack cakes will probably result in decreased profitability for producers, and some may even decide to leave the market.
This decline in demand could affect the profitability of snack cake producers by resulting in lower sales and revenues.
In addition, prices may drop as a result of the decline in demand to entice customers to purchase more of the falling snack cakes.
Thus, Producers make lower profits, and some will exit the market. The correct option is A.

What is the end result of crossing-over during the first stage of meiosis?
-the paternal DNA only is copied onto the chromatids
-the chromatids are identical to each other
-the chromatids contain the maternal DNA only
-the chromatids become non-sister (non-identical) chromatids
Answer:
The chromatids contain the maternal DNA only.
Explanation:
They must contain half the original number of chromosomes. It must contain only one chromosome in place of each homologous pair of chromosomes, so it is endowed with either the maternal or the paternal copy of each gene but not both.
