According to the base-pairing rules for DNA, which of the following statements is
not true?
A always pairs with T.
C always pairs with G.
Talways pairs with G.
Answer:
T always pairs with G
Explanation:
According to the complementary base pairing rule as postulated by Chargaff, an Adenine base (A) will always hydrogen pair with a Thymine base while Cytosine base (C) will always hydrogen pair with Guanine base (G) in a DNA molecule.
That is; A - T and G - C
Hence, based on the question, the pairing of Guanine and Thymine is incorrect.
Explain the reason the Type AB and Type O blood phenotypes always have the same
genotype, whereas the Type A and Type B blood phenotypes have two possible allelic
combinations.
Answer:
Because A is co-dominant to B and O is recessive, so the genotype is the same as the phenotype. But A can have 2 genotypes because A can mask a recessive allele, which makes the phenotype A. B can also mask a recessive allele, which makes the phenotype B.
Examples
AO (genotype) = A (phenotype)
BO (genotype) = B (phenotype)

When observing an ECG, you will see many different deflections from baseline known as waves. These deflections represent various electrical events taking place in the heart that give rise to the mechanical events that help move blood. In addition to the waves that can be observed, there are flat lines between waves and successive cardiac cycles called segments that also represent particular electrical events that take place in the heart. Finally, certain combinations of waves and segments, known as intervals, also identify important events recorded by the ECG. Match each of the following events with the correct phase of an ECG. Drag the terms on the left to the appropriate blanks on the right to complete the sentences.
A. P wave
B. ST segment
C. QRS complex
D. PR segment
E. T wave

When it was time to go outdoors, 3-year-old Casandra said she didn’t want to play and headed for her locker. At the teacher’s gentle insistence, Casandra reluctantly joined the other children on the playground. Tears rolled down her cheeks when the teacher boosted Casandra onto a swing seat and began to push her. The teacher stopped the swing and helped Casandra off. She held her closely for a few minutes and then asked why she was crying. Casandra initially denied that anything was wrong. However, when the teacher persisted, said she "had fallen the night before and hurt her bottom."
The teacher took Casandra inside and asked to see where she had been hurt. When Casandra pulled down her shorts, the teacher noted what appeared to be a large burn with blisters approximately 2 inches in length by 1 inch in width on her left buttock. Several small bruises were also evident along one side of the burn. Again, the teacher quietly asked Casandra how she had been hurt, and once again she replied that she "had fallen."
What actions should Casandra’s teacher take?
Answer:
casandra was scared around others
Explanation:
in the passage i notesed that she went to her locker and started crying
Answer: 1. Casandra's teacher should take her to the nurse and just tell the nurse that she got hurt in the playground 2. The teacher should gather more evidence until she knows that something is going on because she can't prove that something is really happening 3. She shouldn't tell the parent yet because they would probably accuse the teacher of doing it 4. If it was the first time , I would feel bad for the girl and just tell her to be careful but if it kept happening, I would tell the principal and her parents and I would feel angry

What is the answer of the question?
Answer:
A. Amino Acid, protein, gene.
Explanation:
Genomics refers to the scientific study of genes (DNA) found in living organisms such as humans and animals.
A gene can be defined as a complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Simply stated, a sequence of biomolecules which are responsible for coded genetic instructions in all living organisms is known as nucleotides.
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
Furthermore, the two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Additionally, the proteins which are mainly synthesized based on the genetic instruction codes in deoxyribonucleic acid (DNA) determines the trait of living organisms.
Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.
Hence, when you remove a nucleotide from a gene, the order of nucleotides shifts and as such resulting in new amino acid being coded for. These new amino acid will combine to form a different protein than what the gene was originally coded for.
When Joe saw the Rocky Mountains for the first time, he exclaimed, "These Mountains are much younger than ours back East!" Which feature supports his conclusion that the Rockies were relatively young mountains? * a)they have rounded tops b)weathering has not yet hardened the rock c)they have sharp peaks
The statement "they have sharp peaks" is a feature supports his conclusion that the Rockies were relatively young mountains.
What is a mountain?A mountain is an elevated area of the crust of the Earth, typically with steep sides that reveal a substantial amount of bedrock that has been exposed. Although definitions vary, a mountain is often taller than a hill, rising normally at least 300 meters above the surrounding terrain, and differs from a plateau in having a constrained peak area.
it is a landform that rises significantly above the surrounding terrain. Mountains, which are steeper than hills, are created when the Earth's crust's tectonic plates collide and push the land upward where they do. As an alternative, molten rock that has broken through the Earth's surface can also rise up and form mountains.

Indoor air pollutants can be dangerous because the air pollutants stay in small space rather than circulating throughout the atmosphere. Option C is the correct answer.
What is the methane gas ?It is the gas that is produced by the cow dung and the gas is produced by the various chemical reactions in it.
Building materials pollution can be reduced out by many ways. Here are a few examples:
Low-VOC Paints: Volatile Organic Compounds (VOCs) are chemicals found in many paints, which can emit harmful fumes into the air for years after the paint has dried. Low-VOC paints contain fewer or no harmful chemicals, reducing indoor air pollution and improving air quality.
Air-Purifying Plants: Certain indoor plants, such as peace lilies, spider plants, and Boston ferns, can help remove harmful pollutants from the air. These plants absorb pollutants such as formaldehyde, benzene, and xylene, improving indoor air quality.
Green Roofs: Green roofs are roofs covered in vegetation that can help absorb pollutants from the air, reducing air pollution in urban areas. Green roofs also provide insulation, reducing energy costs, and can help mitigate the urban heat island effect.
