what a Lunar Phase ?
Answers
Answer:
It’s something like The lunar phase or Moon phase is the shape of the Moon's directly sunlit portion as viewed from Earth. The lunar phases gradually change over a synodic month as the Moon's orbital positions around Earth and Earth around the Sun shift
Answer with Explanation:
A lunar phase is also known as a "moon phase." This refers to how we see the Moon in different shapes as it is reflected back to Earth. Such reflection depends on the portion of the Moon that is illuminated by the sun. This explains why the amount of moon that we view from Earth changes over time.
It consists of 8 phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter and Waning Crescent.

The sequence of bases on one strand of a DNA molecule is AGT GTA GAC. After replication of the strand of DNA, what is the sequence of nitrogen bases on the complementary (opposite)strand?
Answers
Answer:
TCA CAT CTG
Explanation:
If there is an A, then on the complementary strnad there will be a T (and vice versa) since Adenine (A) always bonds with Thymine (T)
If there is an C, then on the complementary strnad there will be a G (and vice versa) since Cytosine (C) always bonds with Guanine (G)
The sequence of nitrogen bases on the complementary (opposite) strand is TCA CAT CTG
What are complementary strands of DNA?Complementary strand is either of the two chains that make up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases.
The complementary strand for DNA must follow the base pairing and polarity rules. Pairing means that A=T and G=C. Polarity means that the strands have to run in opposite directions.
The upper strand of DNA is the "mRNA-like" strand. The lower strand is the strand that is complementary to the mRNA.

Which of the following normally leads to the production of functional messenger RNA in eukaryotic cells?
Answers
Answer: The removal of portions of RNA known as intervening sequences (introns)
Explanation:
The removal of portions of RNA is known as intervening sequences (introns).
What is the process of splicing?In order to enable the translation of mRNA into a protein, RNA splicing puts together the protein-coding regions (exons) and cuts out the intervening, non-coding segments of genes (introns) from pre-mRNA.
Intron sequences are cut out and exon sequences are joined during the splicing process.
As RNA matures, introns are cut out via RNA splicing, which means that they are not expressed in the resulting messenger RNA (mRNA) product.
In contrast, exons continue to be chemically bound to one another to produce mature mRNA. Exons are expressed sequences, whereas introns can be thought of as intervening sequences.
Therefore, the removal of portions of RNA is known as intervening sequences (introns).

The HeLa cancer call genome is vastly different from Henrietta’s normal genome. A gene transfer from the human papillomavirus 18 virus (HPV18) to human cervical cells created the original HeLa strain of cancer cells.
a) Describe the type of evidence scientists would need to justify this claim.
b) From this discovery, an HPV vaccination was developed. Without HeLa cells, this would not have been possible. Yet, these cells were taken for research without Mrs. Lack’s knowledge. Evaluate the pros and cons of designating biopsy cells as "free cells," cells that can be used without required patient consent.
Answers
Answer:
a. Sequencing the genome and transcriptome of these cells
b. Pros: these cells can be very useful in research (as in Henrieta case)
Contras: 1. patient's family may have inherited the same genetic defect from their common ancestors, thereby this information might be used for malicious people
2. Ethical issues
Explanation:
By using genome sequencing technologies it is possible to determine the nucleotide sequence of the genome (DNA) and their transcriptomic products (i.e., RNAs, especially mRNAs) obtained from a particular cell type. Therefore, these technologies can be used to compare the genome of cancer cells and Henrietta’s normal genome.
HeLa cells have been very useful in pharmaceutical research. These cells have been used in cancer research, in the development of vaccines (e.g., polio vaccine and HPV vaccine), Parkinson's Disease, etc. Moreover, the use of cells without required patient consent may affect the patient’s family by exhibiting information about the genetic conditions of multiple generations of this family, which might be considered unethical and lead to problems associated with the malicious use of this information.
HeLa Cell
It is the first human immortal cell line.
a). The scientist took a tissue sample from a patient named Henrietta Lacks. She was a cervical cancer patient.
Now when the scientist observed the cell sample in the laboratory, they saw that cell was growing indefinitely, i.e. 'immortal'.
So, they named it the HeLa Cell.
Later, the scientist found many copies of HPV-18 (Human Pappiloma Virus-18) in these HeLa cells which is a strain of HPV.
These strains has caused cervical cancer in Henrietta Lacks.
b). The Pros
It could not have claimed if any medical negligence would have occurred.We can overcome the false perception of the patient.The research could be progressed without any interruption from the patient.The Cons
If the consent of the patient was not taken then there would have been legal issues as well as ethical issues.Also, the law orders to stop the research without patient's consent.Without the right patent, the commercialization of the cells would begin.Learn More :

The correct answer is - 12.5 cm3.
Explanation:
Given:
volume = 40000 cm3 (aquarium an hold water)
length and width = 40 cm and 80 cm
Height = ?
Formula:
Volume = length*width*height
Solution:
Putting the value in the formula -
40000 = 40*80*h
h = 40000/3200
h = 12.5

Atom A has six protons , five neutrons and five electrons. Atom B five protons , six neutrons, and five electrons . Are atoms A and B of the same element ?
1. no, because they do not have the same number of protons
2. no, because they do not have the same number of neutrons
3. yes , because they have the same number of electrons
4. yes , because both have 16 protons , neutrons, and electrons combined
Answers
Answer:
no, because they do not have the same number of protons
Explanation:
No of protons represents atomic number which decides the characteristics of an atom . Two atoms having same number of protons but different number of neutrons are same element . They differ only in some physical characteristics . They are called isotopes . In respect of chemical properties they are same . In a neutral element number of protons and number of electrons are same . But in some case number of electrons may differ . In that case they form ions of the element . In positive ion , number of electrons is shorter than number of protons .
In the present case , atom A and atom B differ in respect of number of protons so they represent different element .
