Mass of the moon is 7.4x10^22 kg and its radius is 1740km, Calculate the value of acceleration due to gravity on the surface of the moon. *
Answer:
The gravitational acceleration in the surface of the moon is 1.63 m/s^2
Explanation:
The gravitational acceleration at a distance R of an object of mass M, is given by:
g = G*M/R^2
Where:
G is the gravitational constant.
G = 6.67*10^(-11) m^3/(kg*s^2)
We could think that all the mass of the moon is at its center, then at the surface of the moon, the distance will be equal to the radius of the moon, thus:
R = 1740km
But we want to work with meters, so remember that:
1km = 1000m
then:
1740km = (1740)*1000m = 1740000m
R = 1740000m
And the mass is just:
M = 7.4x10^22 kg
If we input all that in the gravitational acceleration equation, we get:
g = (6.67*10^(-11) m^3/(kg*s^2))*(7.4x10^22 kg)/( 1740000m)^2
g = 1.63 m/s^2
The gravitational acceleration in the surface of the moon is 1.63 m/s^2

Group of answer choices
perfusion
percolation
ventilation
diffusion
Answer:
ventilation
Explanation:
Breathing, also known as ventilation, is the process of moving air or water in order to facilitate the gas exchange between the external and internal (body) environment, mostly to eliminate carbon dioxide (CO2) and bring in oxygen (O2). For example, fish are aquatic animals that need to run water over their gills to get the O2 that they need to survive (gills are organs that create a large surface area for ventilation). Moreover, insects ventilate their tracheal system to get O2. Finally, terrestrial vertebrates (i.e., amphibians, reptiles, birds, and mammals) use organs called lungs to exchange O2 and CO2 between their cells and the external environment.
Describe how oxygen is transported in blood, and explain how temperature, pH, BPG, and affect oxygen loading and unloading.
Solution :
The flow of oxygen in the blood is been transported by two ways :
1. in plasma 1.5%
2. bound to hemoglobin 98.5%
As the oxygen loads in the body, affinity of the Hb makes the oxygen loading very efficient in the blood. The Hb molecule gets saturated when all the 4 hemes are oxygen binded.
The decreased pH weakens the hemoglobin oxygen binding in the tissues.
Higher temperatures in the oxygen means a lower affinity and thus more oxygen is released and so the oxygen unloads.
Increase in the temperature, the BPG and the modification of the structure in the hemoglobin decreases the affinity for the oxygen and further enhances the unloading of the oxygen in the blood.

End result is two diploid cells that are genetically identical to each other and the parent cell Mitosis Melosis Both mitosis and meiosis
Answer:
Mitosis:
A single division occurs, separating sister chromatids
End result is two diploid cells that are genetically identical to each other and the parent cell
Meiosis:
The first division separates homologous pairs; the second division separates sister chromatids
Homologous chromosomes pair up and form chiasmata
Homologous pairs of chromosomes line up on the metaphase plate
Daughter cells contain recombinant chromosomes
End result is four haploid cells that are genetically different from each other and the parent cell
Mitosis and Meiosis:
Chromosomes duplicate during interphase
Process starts with a diploid cell
Duplicated chromosomes line up Individually on the metaphase plate in a diploid cell
Explanation:
Mitosis is the division of vegetative cells while meiosis involves the division of sex cells. Both divisions start with diploid parental cells but while the daughter cells in mitosis are also diploid, those of meiosis are haploid. This is why mitosis is referred to as equational division while meiosis is known as reductional division.
A cell that will undergo mitosis or meiosis would first have its genetic materials duplicated during interphase in addition to the synthesis of other important biochemicals such as proteins. Mitosis involves just a single division of the sister chromatids with two genetically identical daughter cells who are also clones of the parent cells resulting.
Meiosis, on the other hand, involves two divisions - the first one happens to separate homologous chromosome pairs while the second division separates sister chromatids just like in mitosis. During the early stage of meiosis, homologous chromosomes synapsed through the formation of a synaptonemal complex to form tetrads. Thereafter, synapsed chromosomes exchange chromosomal segments at a point known as chiasmata. All these happen at the prophase stage of meiosis I. The paired homologous chromosomes are then lined up at metaphase where they are engaged by the spindle fibers.
Meiosis II and mitosis are more or less the same with the chromosomes condensing at the prophase and the formation of metaphase plates at the metaphase. Sister chromatids are pulled apart and they migrate to the opposite poles at the anaphase and telophase.

(A) unzipping the double helix by breaking down the hydrogen bonds
(B) adding the free nucleotides to the complementary strand of DNA
(C) splitting the DNA molecule
(D)connecting the fragments on the lagging strand of DNA
Answer:
A
Explanation:
the function of DNA polymerase is to unzip the double helix structure of DNA by breaking down the weak hydrogen bond
Answer:
(B) adding the free nucleotides to the complementary strand of DNA
Explanation:
A DNA polymerase is an enzyme capable of creating new DNA molecules by sequentially adding nucleotides to the three prime (3')-end of a DNA strand. A DNA strand is a polynucleotide chain composed of a linear series of nucleotides, each consisting of a deoxyribose sugar, and phosphate, and a base (i.e., thymine, guanine, cytosine and adenine). Before a cell starts to divide, it needs first to replicate its genetic material by using DNA polymerases that duplicate the cell's DNA during the interphase (S phase). During this process (DNA replication), an enzyme known as helicase unwinds the DNA molecule, which is made up of two antiparallel strands oriented in opposite 3′-5′ directions to each other. Subsequently, each strand is used as a template for its replication through DNA polymerases that can add nucleotides (one at time) to an existing short fragment of RNA, i.e., the primer sequence, which is paired with the template DNA strand.
