A cat's coloring is mostly determined by genes on their X chromosomes, which contain alleles for colors, such as black, orange, gray, and cream. The allele for white fur is located on a different gene. Calico cats, by definition, must display three different colors in their fur - white plus two of the other colors. This is easily possible in female cats, because females normally possess two X chromosomes. However, this occurs rarely in male cats, because males typically possess only one X chromosome plus one Y chromosome. What must be the genetic make-up of a male calico cat, and what type of chromosome disorder does this most resemble?
Answer:
XXY, Klinefelter's syndrome
Explanation:
In humans, as well as in many mammals, biological sex is determined by a pair of sex chromosomes (X and Y) which combine to produce a female phenotype (XX) or a male phenotype (XY). In humans, the Klinefelter syndrome (KS) is a chromosomal disorder resulting from two or more X chromosomes in males. In cats, there are documented rare cases in which male cats can also inherit two X chromosomes in addition to the Y chromosome, so they are XXY instead of XY (similar to the Klinefelter syndrome in man). Also in cats, the calico-colored is a phenotype result from the inactivation of one X chromosome, which usually occurs in cat females. However, approximately one in every 3,000 male cats have the XXY condition, and these male cats may also exhibit a “calico” phenotype.

what does a group of zebras make up?
1. Give the names of the
areas of DNA where transcription starts and ends. 2. Which enzyme copies the DNA?
3. What is added to the 3' and 5' ends of the RNA molecule before it leaves the nucleus? 4. Name the structure
that cuts the introns out of the pre-mRNA.
Answer:
1. Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins). RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination. 2. DNA polymerase 3. Before mRNA leaves the nucleus of a eukaryotic cell, a cap is added to one end of the molecule, a poly A tail is added to the other end, introns are removed, and exons are spliced together. Sequence of nucleotides in messenger RNA is translated into a sequence of amino acids. 4. In RNA splicing, specific parts of the pre-mRNA, called introns are recognized and removed by a protein-and-RNA complex called the spliceosome.

What is DNA Transcription?
Transcription is the technique of creating an RNA replica of a gene series. This replica, known as a messenger RNA (mRNA) molecule, leaves the molecular nucleus and enters the cytoplasm, wherein it directs the synthesis of the protein, which it encodes.

Which macromolecule is needed for lactic acid formation and alcohol fermentation to proceed with their processes?
IN YOUR OWN WORDS
DONT COPY FROM THE INTERNET
Answer:
sugar
Explanation:
sugar is the required macromolecule
In the lactic acid formation, pyruvate changes to the lactose which is the anaerobic form of respiration. Pyruvate changes to alcohol and carbon dioxide.
What is the main ingredient for lactic acid fermentation ?It is the sugar molecule that is needed for the lactic acid fermentation.
Both the types of the fermentation requires two primary components which are a sugar supply and bacterial culture where alcohol fermentation uses the forms of the yeast where the lactic acid fermentation usually depends on the lactic acid bacteria.
Lactic acid fermentation takes place in some of the strains of the bacteria and in the even skeletal muscle and even produces lactic acid . Alcoholic fermentation takes place in the yeast and just produces ethanol with carbon dioxide.
Lactic acid bacteria is a type of gram-+ve bacteria which use carbohydrates as only and main carbon source. Later on lactic acid bacteria is generally cocci or rods usually have the strong tolerance to low pH.

The ability to curl the tongue in dominant to the inability to do so. If Eric (heterozygous tongue curler) marries Brandy (also heterozygous) what are the predicted GTs and PTs of the offspring?
Answer:
Genotype = 1CC: 2Cc: 1cc
Phenotype = 3 tongue curler : 1 non-tongue curler
Explanation:
This question involves a single gene that codes for the ability or not to curl the tongue. The ability to curl the tongue (C) is dominant to the inability to do so (c). This means that a heterozygote will be able to curl his/her tongue.
According to this question, If Eric, who is a heterozygous tongue curler (Cc) marries Brandy who is also heterozygous (Cc) i.e. Cc × Cc, the following gametes will be produced by each parent: C and c.
Using these gametes in a punnet square (see attached image), the predicted genotype of the offspring is 1CC: 2Cc: 1cc while the predicted phenotype is 3 tongue curler : 1 non-tongue curler.

at the cellular level, what caused Sally's cancer
Answer:
Uncontrollable cell division.
Explanation:
Cancer is a disease which is caused when cells division is uncontrollable and spread into surrounding cells and tissues. Mutations in genes is also responsible for the cause of cancer because this mutation accelerate the rate of cell division or inhibiting normal controls on the system, such as programmed cell death. When the mass of cancerous cells grows with the passage of time, it turn into a tumor.

Answer:
Natural selection gives organisms what they need
Explanation:
The species constantly evolve because of the changes around them. Natural selection gives organisms what they NEED in order to survive. "Natural selection produces organisms perfectly suited to their environments".
Species that continually evolve because of changes around them where natural selection gives organisms what they need to survive. "Natural selection makes organisms perfectly adapted to their environment".
What is Natural Selection?Natural selection is defined as the differential survival and reproduction of individuals due to differences in phenotype which is a major mechanism of evolution, a change in the genetic properties of populations over generations.
It is the process through which populations of living organisms adapt and change where individuals in a population are inherently variable, meaning they all differ in some way. This variation means that some individuals have better adaptations to the environment than others.
Thus, species that continually evolve because of changes around them where natural selection gives organisms what they need to survive. "Natural selection makes organisms perfectly adapted to their environment".

With regard to iodine, which is hypertonic? [beaker/ tube]
With regard to starch, which is hypertonic? [beaker/ tube]
Needs to be in within a few hours, please help
Answer:
With regard to iodine, beaker is hypertonic whereas with regard to starch, tube is hypertonic.
Explanation:
The beaker has higher amount of iodine solution than the tube so the beaker is considered as hypertonic solution while on the other hand, the tube has more starch concentration than the beaker so the tube is considered as hypertonic solution. In hypertonic solution, the concentration of solutes are higher than the surrounding environment or another solution. So that's why with regard to iodine, beaker is hypertonic whereas with regard to starch, tube is hypertonic.
