Explain the protective significance of chromosomes condensing into tight coils during mitosis.
Answers
Answer:
Chromosomes condense before mitosis to allow them the ability to move smoothly, without becoming entangled and breaking. (So, they are conveniently packaged for cell division, in which the chromosomes must move to both poles of the cell.)
Explanation:Otherwise it would be a mess as they get tightly packed
The rat snake is found in many different environments. They are found in woods, along the coast, in cities, and in mountains. They eat rats, birds, mice, and squirrels. Rat snakes also have varied appearances. They are gray, yellow, black, and mixes of these colors, depending on where they live. Which of the following explains the differences in colors of the rat snake?
A. The rat snakes' colors vary because they eat different foods in different environments that make their skin color change.
B. The rat snakes' colors vary as a result of artificial selection, which allows them to choose the best color suited for their environment.
C. The rat snakes' colors are adaptations caused by natural selection, which help them blend into their environment and hunt for food.

hope this helps (:
The mutation shown here is point mutation.
What is mutation?"A changes/alteration in nitrogenous bases sequence of DNA that can results in changes in the genotype and phenotype of an organism is known as mutation."It occurs due to: deletion, insertion, translocation and inversion.During insertion, an extra nitrogenous bases are added to the DNA sequence.During deletion, a nitrogenous bases are removed from the DNA sequence.During inversion, the sequence of nitrogenous bases gets inverted in a DNA strand.In translocation, a sequence of one DNA strand breaks off and attaches to another DNA strand.What is point mutation?"A point mutation occurs in a genome when a single base pair is added, deleted or changed."Here, the sequence of original strand is A T A C A C and the sequence of mutant one's is T T A C A C. The base A is changed into base T.
Hence, the correct option is: D. Point mutation.

The genetic code for one amino acid molecule consists of A) five sugar molecules B) two phosphates C) three nucleotides D) four hydrogen bonds
Answers
Answer:
c
Explanation:
The genetic code for one amino acid molecule consists of three nucleotides. Thus option C is correct.
What is genetic code?
Genetic code is defined as a sequence of instructions that directs the translation of DNA into 20 amino acids, which are the basic building blocks of proteins in living cells.
It can also be defined as the collection of instructions that live cells follow to convert information stored in genetic material into proteins.
Nucleotides are defined as a three-subunit chemical molecule consisting of a nitrogenous base, a five-carbon sugar, and a phosphate group.
It can also be defined as the fundamental building component of nucleic acids.
There are basically two types of nucleotides.
Purines - They are defined as a heterocyclic aromatic organic molecule composed of two fused rings. Adenine, guanine and hydro xanthine are purines.Pyrimidine - They are defined as a simple aromatic compounds with a six-membered ring of carbon and nitrogen atoms. Cytosine, thymine and uracil are pyrimidines.Thus, the genetic code for one amino acid molecule consists of three nucleotides. Thus option C is correct.

what is theory of to observe the neucles in cheek cells
Answers
Answer: The theory of cheek cells is used for the identification of cheek cells.
Explanation:
The cells of cheek do not have cell wall. They have a cell membrane which allows on certain molecules to pass through it. The nucleus is located centrally in the cheek cells and it stores the DNA. It can be stained with the help of the methylene blue reagent. It appears blue in color which can be observed under the microscope. The cheek cells can be isolated from the buccal cavity by using cotton buds and cotton swabs can help in isolating the cells.
Before mitosis begins, what happens during S-phase?
Answers
Answer:
the S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. in this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
in S phase, the cell synthesizes a complete copy of the DNA in its nucleus. it also duplicates a microtubule-organizing structure called the centrosome. the centrosomes help separate DNA during M phase.

If Individual 3 has children with a woman that is heterozygous for the genetic disorder, what is the probability they will have an affected child?
Answers
If Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.
What is the genetic disorder?A recessive genetic disorder, such as cystic fibrosis, and an autosomal dominant disorder, such as Huntington's disease, are examples of genetic disorders caused by a gene that can express itself in either a dominant or recessive manner. For example, the disease is represented by the aa. If the male is heterozygous for diseases such as "Aa," then he will produce 25% "aa" type offspring when he crosses with the heterozygous female. When a man is purebred AA and crosses with a heterozygous female, then no offspring will be genetically infected.
Hence, if Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.

A cow has alleles for both black and
white fur that are codominant. What
would be the resulting appearance
of the cow?
A. a solid coat of gray fur
B. fur with areas of both black and white
C. it is impossible to determine
Answers
Answer:B
Explanation:
Codominant is when neither allele is recessive so they are both expressed in the phenotype
A cow having the codominant alleles for both white and black fur will appear to have fur with areas of both black and white fur. This is an example of co-dominance where both alleles are expressed in the different parts of the animal. So option B is correct.
What is codominance?In codominance, two different versions of a gene are expressed separately and they are expressed equally in different parts of the organism. As a result, the traits of both alleles are expressed simultaneously. The term co-dominant means that both alleles are dominant and one allele does not mask the expression of the other.
Co-dominance can easily be spotted in plants and animals. Codominance is observed in some traits that are less visible like blood type. The A and B alleles are codominant and they can be expressed simultaneously.

You need to compare the location of bands for X and X's child. X is the mother, so the child will have half of all its bands from its mother, and the other half must be from the father. Some bands that X and X's child have in common are at around 185bp and 130bp (it is difficult for me to determine the exact position). Then look at the bands which X and X's child do not have in common. Those bands must have come from the father. So now you compare the remaining bands to all the bands of Megabucks and see if they match up. You can see a band at around 60bp that the child has. The mother did not have this band, so it must have come from the father. Megabucks does not have this band, so he is not X's father.
Explanation:
I hope this has helped you a little. The main thing to know is that a child's bands come from their mother and father, so if half the bands match up to the mum, the other half have to match up to some of the father's bands. But a child will never have the same set of bands as one of their parents - it will be a mix of both parents' bands.
