The force exerted by blood inside the arteries is known as blood pressure. It differs depending on where on the body the person is.
As a result, it is always measured in the upper arm artery, the largest artery in the upper arm. Our blood is descending due to gravity. Gravity pulls the blood downhill, thus as you lift or lower your arm, the blood volume at the height of the cuff changes slightly yet significantly. Sit in a chair with your feet flat on the ground while holding your arm up so your elbow is roughly at heart level in Blood pressure. The cuff's inflatable portion ought to completely encircle at least 80% of your upper arm.

Explanation:
What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?
Answer:
Base substitution mutation
Explanation:
Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:
ATCGGCTTAACG to ATCGGCTAAACG
This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.
Genomic imprinting may involve a single gene, a part of a chromosome, or a whole chromosome. Indicate if the following statements are true or false regarding this phenomenon
1. Genomic imprinting is permanent in the somatic cells of a given individual. _____________
2. Genomic imprinting is permanent and affects future generations. ____________
3. Methylation is the chemical change underlying genomic imprinting. _____________
4. If a gene is imprinted, the offspring can express both the maternal and paternal allele. _________
Answer:
1. True.
2. False.
3. True.
4. False.
Explanation:
A genome can be defined as the complete set of hereditary instructions that is typically found in the deoxyribonucleic acid (DNA).
Genome imprinting can be defined as an epigenetic biological process in which a genomic domain or genes of a living organism is marked biochemically with information that is related to parental origin. Thus, it is a non-Mendelian inheritance i.e genome imprinting is typically independent of Mendelian inheritance.
1. True: Genomic imprinting is permanent in the somatic cells of a given individual.
2. False: Genomic imprinting is permanent and affects future generations. It does not affect future generations because generally it is expressed in a parent of origin specific form.
3. True: Methylation is the chemical change underlying genomic imprinting.
4. False: If a gene is imprinted, the offspring can express both the maternal and paternal allele. It is independent of Mendelian inheritance.
How is energy stored when ADP is converted to ATP?
Answer:
Energy is stored in the bonds between the phosphate groups (PO4-) of the ATP molecule. When ATP is broken down into ADP (adenosine diphosphate) and inorganic phosphate, energy is released. When ADP and inorganic phosphate are joined to form ATP, energy is stored.

the structure labeled A in the figure below is called the
Answer:
Centromere
Explanation:
Connects sister chromatids
The structure labelled A in the figure is a centromere.
What is a centromere?The centromere is a region of the chromosome that is constricted. The centromere plays an important role in the division of cells during both the processes of mitosis and meiosis.
The centromere is simply the region of the chromosome where the spindle fibres attach. Therefore, when the spindle fibres attach to the centromere, they pull the sister chromatics in the opposite directions of the cell during cell division.
Thus, at the end of the cell division, each of the daughter cells gets one-half of the chromosome containing identical DNA. The centromere is thought to be the middle region of the chromosome, even though it is often not in the middle. It is simply the region where the chromosomes are most constricted
The centromere separates the chromosome into the P arm and the Q arm. These are simply the names given to the short arm and the long arm of the human chromosome respectively.

why is the moon invisible from earth during a new moon science
Answer:
Explanation:
During the New Moon the far side of the Moon is illuminated by the Sun, while the side that faces the Earth lies in darkness so the Moon is invisible. As the Moon follows its path from the New Moon position more and more of the Earth-facing side becomes illuminated resulting in the “waxing” phases.

The gecko is a reptile that has the amazing ability to climb smooth surfaces - even glass. Recent discoveries indicate that geckos stick to smooth surfaces via van der Waals interactions between septae on their feet and the smooth surface. When not selling car insurance, geckos climb smooth surfaces.
a. How is this method of stickiness advantageous to the gecko over covalent interactions?
b. Given that van der Waals forces are among the weakest molecular interactions, how can the gecko's feet stick so effectively?
Answer:
a) This method of stickiness is advantageous over covalent interactions because it is weak and easily reversible.
b) The feet are equipped with millions of septae which collectively produce a synergistic effect that produces a powerful adhesive effect.
Explanation:
Geckos have their feet studded with tiny hair-like substances called septae, and these substances interact with the surfaces on which the Gecko climbs using weak van der Waals forces to produce stickiness.
a) The van der Waals interactions for the purpose of climbing is of more advantage over the covalent method of interaction because climbing involves a repetitive action of adhesion to the surface and destruction of such adhesion, and this involves the creation and the breaking of the bonds between the two surfaces easily. van der Waals forces being easily broken helps to achieve effective climbing. If the method of interaction is with a comparatively strong bond, the speed of creation and destruction of such bond is reduced, and the effectiveness of climbing is reduced.
b) Although van der Waals forces are weak forces, each foot of the wall Gecko has millions of septae that each create a van der Waals interaction, and the collective interactions produce a powerful adhesion causing the feet to stick effectively.
The article mentions the six rules for choosing effective supporting materials. Name the three you feel are the most important and explain why you feel this way. (Site 1)

Club foot is one of the most common congenital skeletal abnormalities, with a world-wide incidence of about 1 in 1000 births. Both genetic and nongenetic factors are thought to be responsible for club foot. C.A. Gurnett et al. identified a family in which club foot was inherited as an autosomal dominant trait with reduced penetrance. They discovered a mutation in the PITXI gene that caused club foot in this family. Through DNA testing, they determined that 11 people in the family carried the PITXI mutation, but only 8 of these people had club foot. What is the penetrance of the PITXI mutation in this family
Answer:
0.727
Explanation:
Penetrance can be defined as a measure of the association between a genotype and phenotype. In medical genetics, the penetrance of a mutation leading to the disease state is the proportion of individuals carrying the mutation and showing disease symptoms associated with such mutation. For example, if a mutation leading to the disease state has a 90% of penetrance, it is expected that 9 of each 10 individuals carrying the mutation will develop the disease, while the remaining 10% will not develop the disease. In this case, 8 of each 11 individuals carrying the PITXI mutation show symptoms compatible with the disease, and therefore the penetrance is 8/11 = 0.727 (73%).
