Answer:
a. Developing cells may express different parts of their identical genetic instructions.
Explanation:
Humans are multicellular organisms i.e. we possess many cells in our body. These cells increase as a result of division. Although all of the cells of humans develop from one fertilized egg (zygote), the human is born with many different types of cells because of a process called CELL DIFFERENTIATION.
Cell differentiation is a process in multicellular organisms where a cell becomes more specialized in function as it divides. The set of genes contained in each cell are not expressed simultaneously i.e. some genes are expressed while others are repressed. This is how cells with the same gene possess different functions. Therefore, according to this question, developing cells may express different parts of their identical genetic instructions to be of different types.

Use complete sentences or list form in order to describe the steps of replication. You must
use the following words and underline them:
Nucleus Helicase
Complementary strand
DNA Polymerase Ligase
Okasaki Fragments 5’ to 3’ Leading strand
Lagging strand
Answer:
Please find the description below
Explanation:
DNA replication involves the duplication of the DNA molecule in the NUCLEUS to yield two identical copies. It involves the following steps:
- DNA molecule (double stranded) is unwound or separated into a replication fork by DNA helicase.
- The DNA, which now comprises of two single strands i.e. one strand that runs from the 3'-5' called LEADING STRAND and other strand that runs from '-3' called LAGGING STRAND.
- An enzyme called DNA POLYMERASE attaches to the DNA and adds nucleotide in a bidirectional pattern i.e. adds nucleotide to the leading strand in a 5'-3' direction, then adds short pieces of DNA called OKAZAKI FRAGMENTS to the lagging strand.
- The synthesis of nucleotides by DNA polymerase follows the COMPLEMENTARY BASE PAIRING rule i.e. A-T, G-C.
- Another enzyme called DNA LIGASE joins the okazaki fragments together into a whole DNA.
At the end of replication process, two identical copies of DNA is produced, with each containing one old strand and one new complementary strand.
Which of the following statements are true about hydrogen bonds? (More than one)
A.) A hydrogen bond is stronger than a covelent bond.
B.) They are the strongest bonds that form between molecules.
C.) The attraction between the hydrogen atom on one water molecule and the oxygen atom on
another water molecule is an example,
D.) A hydrogen bond is stronger than an ionice bond.
Answer:B,C
Explanation: covalent and ionic bonds hold molecules together. It is the polarity of covalent bonds that give rise to hydrogen bonding. As in the water example: the more electronegative O attracts electrons slightly more than the hydrogens, so the O has a fractional negative charge, the Hs a slight positive charge. The O of one molecule and the H of another are held together by this charge difference.
B.) They are the strongest bonds that form between molecules.
C.) The attraction between the hydrogen atom on one water molecule and the oxygen atom on another water molecule is an example,
Hydrogen bonds exists between molecules in which hydrogen is bonded to a high electronegative atom such as nitrogen, chlorine, fluorine, sulphur etc.
Hydrogen bonds are strong intermolecular interactions. They are responsible for the high boiling and melting points of some polar substances such as water.
However, hydrogen bonds are not as strong as covalent or ionic bonds.

Why phage is consider as a nanomachine?
Answer:
phages are non-living biological entities that can produce numerous copies of themselves, forming ordered three-dimensional structures on a nanometre scale
Explanation:
A phage (i.e., a bacteriophage), is a virus capable of infecting and replicating within bacteria. Bacteriophages are composed of proteins forming a capsid that encapsulates the genetic material (either DNA or RNA genome), which may contain a variable number of genes. Bacteriophages, and viruses in general, can be considered nanomachines capable of producing numerous copies of themselves with high fidelity by utilizing the molecular machinery of the host bacterial cell. In biotechnology, it has been proposed to exploit the knowledge about bacteriophage reproduction to design diverse nanostructures.

Explanation:
xperimenters found that in rats, a certain type of cell will fire when the animal is in a specific location and not when it is in another location. This type of cell is referred to as a _____ cell.
Answer:
hippocampal place
Explanation:
A type of cell that fires when rats are in a specific location as opposed to some other locations are known as place cells.
Generally, place cells are specially shaped neurons whose origin is the hippocampus. These neurons fire or become more active when animals are in certain locations in its environment, as opposed to their overall environment.
The cells are from regions CA1 and CA3 of the hippocampus and collectively act as a cognitive representation of these locations where they are limited to firing. The locations where the neurons are limited to firing are referred to as place fields.
Hence, the cells found in the rat as shown by the illustration are referred to as the place cells whose origin is the hippocampus.

One result of meiosis is the formation of gametes
A. True
B. False
Answer:
T
Explanation:
It is true that the result of meiosis is the formation of gametes. Therefore, option A is correct.
What is meiosis?a unique method of cell division in which the amount of DNA received by each daughter cell is halved compared to the parent cell. In mammals, meiosis takes place during the development of egg and sperm cells.
Since meiosis involves two rounds of cell division, a beginning cell can generate four gametes (eggs or sperm). Cells move through prophase, metaphase, anaphase, and telophase with each round of division.
Chromosome reduction, or meiosis, is the process that enables the generation of haploid germ cells required for sexual reproduction. Meiosis also plays a crucial function in promoting genetic variety and making it easier for recombination to correct genetic flaws. Hence, option A is correct.

a glass marble has a volume of 5 cm3 and a mass of 13 g. what is the density of the marble
Answer:
density = Mass/volume
therefore, d= 13/5 = 2.6g/cm3
Explanation:
please change subject of your question next time, this is maths or phy not biology :-)
The density of glass marble that has a volume of 5 cm3 and a mass of 13 g is found to be 2.6 g/cm3.
What is Density?Density may be defined as a type of physical quantity that measures the degree of compactness of a substance. It may also be characterized as the substance's mass per unit of volume. The symbol most often used for density is ρ (row).
According to the context of this question,
The mass of a glass marble = 13 g.
The volume of a glass marble = 5 cm3.
The formula for calculating density is as follows:
Density = Mass/volume.Density = 13 g/5 cm3 = 2.6 g/cm3.
Therefore, the density of glass marble that has a volume of 5 cm3 and a mass of 13 g is found to be 2.6 g/cm3.

2. Many people believe that a mutation will always result in the formation of a deadly tumor, or the development of a major body defect.
Explain why this is incorrect.
. There are multiple types of mutations in DNA. ______________mutations occur when a single base is changed to a different base pair.______________mutations remove one or more bases from a segment of DNA, resulting in a frameshift mutation. __________mutations are also considered frameshift mutations, and occur when one or more extra bases are added to a segment of DNA.
Answer:
substitution; deletion; insertion
Explanation:
Mutations are genetic changes generally associated with deleterious effects. However, mutations may not have an effect on the phenotype of the organism and even, eventually, they are beneficial. For example, a missense substitution occurs when a nucleotide is replaced by another that changes the encoded amino acid, which may have deleterious or beneficial effects (depending on the new protein and its effects on the fitness of the individual in a particular environment), while a silent substitution does not modify the encoded amino acid and thereby it has no effect on the phenotype. On the other hand, a frameshift mutation is a mutation that involves the insertion or deletion of a nucleotide base, thereby irreversibly altering the Open Reading Frame (ORF) of the protein.
