Explanation:
When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder. In some cases, gene mutations are so severe that they prevent an embryo from surviving until birth.Over time, a mutation might take place in one of the descendant cells, causing increased activity of a positive cell cycle regulator. The mutation might not cause cancer by itself either, but the offspring of this cell would divide even faster, creating a larger pool of cells in which a third mutation could take place.

What are the dimensions of the human skeleton?
Answer
Human skeleton, the internal skeleton that serves as a framework for the body. This framework consists of many individual bones and cartilages. There also are bands of fibrous connective tissue—the ligaments and the tendons—in intimate relationship with the parts of the skeleton. This article is concerned primarily with the gross structure and the function of the skeleton of the normal human adult.

DNA libraries are useful for identifying and isolating eukaryotic DNA fragments of interest in research. Select the ways in which genomic and cDNA libraries differ.
a. Genomic libraries are difficult to express in prokaryotic cells, which lack a splicing mechanism.
b. cDNA libraries contain only the sequences from genes that are expressed in an organism.
c. cDNA libraries are the DNA fragment collections that are stored and propagated in host cells through cloning.
d. cDNA libraries contain more sequence information than genomic libraries.
The ways in which genomic and cDNA libraries differ is that the Genomic libraries are difficult to express in prokaryotic cells, which lack a splicing mechanism. Thus, the correct option for this question is A.
What do you mean by Genomic libraries?Genomic libraries may be defined as a group of overlapping segments of genomic DNA that is significantly cloned into a backbone vector, which statistically includes all regions of the genome of an organism efficiently in order to function normally.
On contrary, cDNA libraries may be characterized as the collection of cloned DNA sequences that are complementary to the mRNA and were remarkably extracted from an organism or tissue in order to stimulate its function.
Therefore, genomic libraries are difficult to express in prokaryotic cells, which lack a splicing mechanism is one of the ways in which genomic and cDNA libraries differ.

11. An individual who is heterozygous for rob(13;14) is at increased risk for having a child affected by Patau syndrome. Please briefly explain why.
Answer:
because of Chromosome-13 rearranges with with other chromosome.
Explanation:
To understand and be and be able to solve or tackle this question effectively, there is need to know the meaning of the important terms in this question/problem.
- Robertsonian translocation: The term "Robertsonian translocation" simply refer to some kind of disorder in the chromosome in which a different kind of chromosome attach itself to another kind of chromosome, that is to say we have more than two fusion of chromosome that are different on chromosome 13, 14,15,21 and 22.
- Patau syndrome: The syndrome known as " Patau syndrome" is also refer to as Trisomy 13. The syndrome is a kind of abnormalities on the 13th chromosome known as chromosome 13. Patau syndrome patient will have more than two[usually three] kinds of chromosome.
"An individual who is heterozygous for rob(13;14) is at increased risk for having a child affected by Patau syndrome. " is TRUE
A defect in chromosome 13, that is to say the Robertsonian translocation on the 13th chromosome is what causes Patau syndrome. The Robertsonian translocation occurs by addition and subtraction of chromosomes, when there is addition on chromosome 13 or say the rearrangement of chromosome-13 with other chromosome, then, the individual's offspring has the tendency of developing Patau Syndrome.

What is the nebular hypothesis?The most widely accepted theory in cosmogony to explain how the Solar System formed and evolved is the nebular hypothesis. It implies that gas and dust orbiting the Sun are what created the Solar System. The nebular theory proposes that a rotating cloud of material called a nebula, composed primarily of light components, flattened into a protoplanetary disk and developed into a solar system made up of a star and circling planets.Immanuel Kant developed the hypothesis.In 1900, Chamberlain and Moultan hypothesized that a wandering star's approach to the sun caused a cigar-shaped extension to separate from the solar surface.Learn more about the nebular hypothesis here:

Except for a pairing of sex chromosomes, homologous
chromosomes_______.
a. carry the same genes
b. are the same shape
c. are the same length
d. all of the above
Answer:
Homologous chromosomes carry the same genes and have the same shape and length, so all the choices are correct.
Explanation:
The homologous chromosomes are so called because each of them has the same DNA molecule, giving rise to the same genes, distributed in the same location within the chromosome.
Somatic cells are diploid, which means that the genetic information that determines specific characteristics is distributed in pairs. Each of the chromosomes that form a pair comes from the father and mother, and the members of a pair are known as homologous chromosomes.
The homologous chromosomes are characterized by having the same shape and size, and contain the same genes, although the information contained in them —the alleles— may be different. Hence the possibility that one allele is dominant and another recessive on two chromosomes of a pair.

Which words best describe this data?
accurate and precise
falsified and inaccurate
invalid and redundant
redundant and falsified
Answer:
accurate and precise
Explanation:
Given:
True value = 10.4 grams
Measured values = 10.2 grams, 10.4 grams, 10.3 grams, 10.4 grams, and 10.5 grams.
Solution:
To a very reasonable extent, the values measured given are accurate and precise.
Accuracy is the nearness of the measured value to the true value. We can see that the measured value would have a mean of 10.36grams which is very close to the true value on approximation.
Precision is the ability to repeat a given set of values from a measurement. The measured values are quite precise.

a. sulfur
Explanation:
Sulfur is an example of a nonmetallic mineral
Non-metallic mineral
Non-metallic minerals are the minerals that do not contain metals, eg limestone, mica, coal etc. Such materials lack metallic characteristics like good electric and thermal conductivity, luster, rigor and malleability.
Sulfur is a non-metallic element with atomic number 16. It is considered as non metal because:
It is poor conductor of heat and electricity. Its density is lower than that of all metals. The electronegativity of sulfur is very high as compared to other metals. It is multivalent atom which is tasteless and odorless.

You are curious about the effects of different watering schedules on your favorite fruit, strawberries. You set up plants, all the same age and size, and plant them in identical pots with the same potting soil. You water them once a week, every day, or every other day. Every day, you check the plants for strawberries, and record the number and size of the berries produced by each plant.
The complete question is as follows:
What is the independent variable in this strawberry experiment?
O the type of pots
O the number and weight of strawberries produced
the potting soil
O the water schedule
O size and age of plants
Answer:
The correct answer is - the watering schedule.
Explanation:
Independent variable is the variable or the factor which is changed or manipulated during a study or experiment to find the effect on the dependent variable.
The variable that is manipulated in this experiment is the watering schedule and the aim of the experiment is also finding the role of the effect of the watering schedule on fruit production. In this study, the watering schedule is manipulated for different pots of plants to see the effect on the production of fruit.
