Answer:
Pyruvate is turned to lactate via a process called fermentation
Explanation:
Pyruvate is the product of the initial stage of cellular respiration called GLYCOLYSIS. Pyruvate is produced in the cytoplasm where glycolysis occurs. The fate of pyruvate i.e. what will eventually happen to pyruvate, is determined by the presence or absence of oxygen.
In the absence of oxygen i.e. anaerobic condition, pyruvate is converted into lactate in a process called FERMENTATION. The NADH produced during glycolysis is reoxidized to form NAD+ in the process.

In working with Drosphilia it is common to use a balancer stock to maintain mutations of interest. The balancer chromosomes are generally carrying multiple inversions on them. What effect would the inversions have on meiosis
Answer:
Fusion or pairing does not occur.
Explanation:
Inversions mutation leads to lowered fertility due to production of unbalanced gametes in the meiosis cell division. Chromosome inversions have no effect on mitosis, but they has affect meiosis because inversions changes the gametes which is only present in meiosis. If an inversion present is in the heterozygous condition, pairing of chromosomes cannot occur in a simple linear fashion due to change of sizes. But if the inverted chromosome segment has the proper size so it can paired with each other.
What is the difference between cellular respiration and gaseous exchange
Answer:
Gas exchange is the intake of oxygen and the excretion of carbon dioxide at the lung surface. Oxygen moves into the blood and carbon dioxide moves out of the blood. Cell respiration is the process that releases energy from the food

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.

Answer:
Man (dimples and freckles) - FfDd
Woman (no dimples and no freckles) - ffdd
Child (no dimples and no freckles) - ffdd
Explanation:
According to this question, the possession of freckles (F) and dimples (D) are the dominant traits. The union of a man with dimples and freckles and a woman with no dimples and freckles (ffdd) gave rise to a child that has no dimples or freckles (ffdd).
Since the child has a recessive 'ffdd' genotype, it means that the father will likely have a heterozygous genotype (FfDd). Therefore, the genotypes of the three persons involved are;
- Man (dimples and freckles) - FfDd
- Woman (no dimples and no freckles) - ffdd
- Child (no dimples and no freckles) - ffdd

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

Plants as well as brown, green, and red algae show a basic life cycle which involves the alternation of generations between a(n) egg and a sperm. seed and a cone. spore and pollen. megaspore and a microspore. sporophyte and a gametophyte.
Answer:
The correct answer is ''sporophyte and a gametophyte''
Explanation:
Plants have a diplohaplon life cycle: a haploid adult plant, called a gametophyte, and a diploid adult plant, called a sporophyte. In green algae, the two generations, sporophyte and gametophyte, are independent and generally the same size. This type of life cycle is found not only in many multicellular green algae, but also in brown algae and red algae. In vascular seedless plants, including ferns, gametophytes, although still independent, are smaller in size than sporophytes. In seed plants, the gametophytic generation is further reduced and is totally dependent on the sporophyte.

Complete tetanus occurs when the muscle is stimulated repeatedly at a high rate, eliminating a relaxation phase, the amount of tension gradually increases to a steady maximum tension.
What is Complete tetanus?A tetanic contraction is also called as tetanized state, tetanus, or the physiologic tetanus, the latter is used to differentiate from the disease called tetanus, which is a sustained muscle contraction that is evoked when the motor nerve which innervates a skeletal muscle emits action potentials at a very high rate than usual action potential production rate.
Complete tetanus is also called fused tetanus. It occurs when the frequency of stimuli increases still further than normal. In this case, the individual muscle contractions completely fuse to produce one large enough muscle contraction in the body.

The enzyme lactate dehydrogenase is responsible for fermentation of pyruvate to form lactate. This process occurs in red blood cells and in muscle cells during intense exercise. Why is fermentation a necessary process for these cells to meet their energy needs
Answer:
Fermentation is a process that happens in the absence of oxygen and it involves the conversion of Pyruvate to lactate.
Cells in the body need constant energy supply to cater for the various demands of our everyday activities and to ensure that they function optimally.
Oxygen supply is an important factor in ATP generation and in cases where there is a lack of it the body system adjusts itself to produce the energy anaerobically. This usually involves the conversion of pyruvate to lactate which aids the breakdown of glucose thereby supplying it to cells of the body.

Answer:
B. Before sperm and egg cells form.
Explanation:
An organism become a juvenile during its life cycle before sperm and egg cells form. juvenile is a stage in which organism is immature and young. The y just enter into the young stage. Every animal has three basic stages in their life cycles that starts as a fertilized egg, developing into an immature juvenile, and then transforming into an adult. The first stage occurs when the fusion of sperm and egg cells occur whereas adult is the mature stage of that organism.
