The dna in nucleosomes is folded in a highly structured way to eventually form _______, which carry different portions of an organism’s genetic information
Answers
A DNA in nucleosomes is folded in a highly structured way to eventually form chromosomes, which carry different portions of an organism’s genetic information.
What are chromosomes?Chromosomes are thread-like structures that are found within the nucleus of animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA).
DNA, which is passed down from parents to offspring, contains the specific instructions that distinguish each type of living creature.
A nucleosome is a section of DNA wrapped around a protein core. DNA forms a complex with proteins called chromatin inside the nucleus, allowing the DNA to be condensed into a smaller volume.
Thus, a DNA in nucleosomes is folded in a highly structured way to eventually form chromosomes, which carry different portions of an organism’s genetic information.

Mr. Chavez wants his class to prepare a procedure that would demonstrate cellular diffusion. Which of the following procedures would best demonstrate cellular osmosis?
A. A procedure that uses the skins of potato left overnight in oil
B. A procedure that uses a cluster of grapes left overnight in a high concentration of salt water
C. A procedure that uses a 2-liter bottle filled with oil and water and left overnight
D.A procedure that uses a banana that has been left overnight in milk
Answers
Answer:
B
Explanation:
The second option correctly shows the process of cellular osmosis.
When the grapes would be immersed in water, the molecules of water move across the cell membrane from the region of low to high solute concentration. Due to this, the water would leave the cells and diffusion of water from the cells of the grapes. Thus, option B is the correct answer.
In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).
Osmosis refers to the movement of a solution (often water) across a selectively permeable membrane.This movement (osmosis) is due to the difference in solute concentrations on both sides of the semipermeable membrane.In osmosis, water molecules move from a region of low concentration of solutes (e.g., salt) to a region of high concentration of solutes.
In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).

Answers
The common atrium is subdivided into a left and right atrium by an interatrial septum, which consists of two parts: the septum primum and the septum secundum that partially overlap.
What is septum primum and septum secundum?
The septum primum, which divides the right from the left, is a structure inside the primitive atrium. In the direction of the endocardial cushions, this septum descends. The foramen primum, a hole in this septum, keeps the blood flowing through the heart. The foramen secundum develops as the foramen primum shrinks in size.What is the purpose of septum secundum?
A muscular flap called the septum secundum plays a significant role in heart growth. It has a semi-lunar form and develops from the atrium's upper wall to the right of the septum primum and ostium secundum. It is crucial for the foramen ovale to close after birth.Learn more about septum secundum

which type of crop accounts for most of the word's genetically modified crops?
Answers
The type of crop that accounts for most of the world's genetically modified crops is soybeans. Genetically modified crops are plants whose DNA has been modified using genetic engineering techniques.
They are created to improve their resistance to pests, herbicides, or extreme weather conditions, among other things. The first genetically modified crop to be introduced commercially was the Flavr Savr tomato in 1994.
Since then, the number of genetically modified crops has increased significantly, with soybeans being the most commonly modified crop. Soybeans account for about 50% of the world's total area planted with genetically modified crops.
The United States, Brazil, and Argentina are the three largest soybean-producing countries, and together they account for 80% of global production. About 90% of soybeans grown in the United States are genetically modified.

Answer:
An independent variable
Explanation:
An experiment consists of two variables viz: independent and dependent variable. Independent variable is the variable that the experimenter controls in order to influence or effect a change in the measurable variable called dependent variable. As the name suggests, the dependent variable is dependent on the independent variable.
For example, a scientist is trying to conduct an experiment on how the caffeine level in different types of drink affects the time of sleep in individuals. The independent variable in this experiment is the TYPE OF DRINKS because it is the variable controlled by the experimenter in order to influence the time of sleep (measurable outcome).

Mendel studied discrete, qualitative traits in peas. This organism helped him induce the rules of inheritance. His work dealt with simple dominant/recessive relationships between alleles. However, expression of many traits are not governed by a single gene, rather can involve multiple genes as well as additive effects. This kind of inheritance pattern is known as quantitative (See Cogbooks -> Genetic analysis of populations for more information). Edward M East (1916) studied a continuously varying phenotype characteristic in Nicotiana longiflora. He took pure-breeding lines of N. longiflora growing long corollas and crossed them with pure-breeding lines growing short corollas. After crossing these lines, F1 offspring had an intermediate length for corolla and had same variation level as in parents. But found a very different result for F2 and F3 than expected.

Protein Synthesis In Eukaryotes Is Similar To The Process In Prokaryotes In That Both Eukaryotes And Prokaryotes a. Have Introns. b. Have Exons. c. Use Methionine As The "Start" Amino Acid. d. Require SnRNPS e. Use Codons To Determine Polypeptide Sequences.
Answers
The Eukaryotes and Prokaryotes differ in many aspects of protein synthesis. But they both use codons to determine polypeptide or protein sequences. So the correct similarity about these is option e.
The protein synthesis in both Eukaryotes and Prokaryotes varies in many aspects. The start codon in Eukaryotes codes for the amino acid methionine (Met) but for Prokaryotes, it is formyl methionine (fMet). Prokaryotes have only the coding sequences called exons but eukaryotes have both introns and exons sequences in their genome.
The small nuclear ribonucleoproteins (snRNP) play a major role in the splicing process in Eukaryotes. Both Eukaryotes and Prokaryotes use three-letter nucleotides called codons. These codons code for a particular amino acid and determine the polypeptide sequences. Therefore, the required option is e.

Answers
The answer for the first blank is “one”.
The answer for the second blank is “dominant”.
The answer for the third blank is “gain” of function.
Proto-oncogenes need or demand only "one" allele (gene copy or variant) to be altered in order to cause cancer (changes in the deoxyribonucleic acid or DNA). One allele is all that is required for a proto-oncogene to develop into an oncogene that causes cancer. Since only one allele (or gene copy) is required to create an oncogene that induces cellular transformation and resulting in cancer, it is referred to as a "dominant" mutation. This type of mutation causes a "gain" in function since the affected cells can now divide uncontrollably and serve a new purpose.
