why do cells made in meiosis have less genetic material than other cells?
Answer:
The cellular division in meiosis I is called the reduction division because it results in the reduction of the chromosome number from diploid (cell has two copies of each chromosome, one maternal and one paternal chromosome) to haploid (cell has only one copy of each chromosome, either maternally-derived or paternall.

Explanation:
Each of the following medical problems involves a malfunction of an organelle or other cell structure. In each case, identify the organelle or structure involved, and indicate whether it is likely to be underactive or overactive.
a. A girl inadvertently consumes cyanide and dies almost immediately because ATP production ceases.
b. A boy is diagnosed with neonatal adrenoleukodystrophy (NALD), which is characterized by an inability of his body to break down very-long-chain fatty acids.
c. A young man learns that he is infertile because his sperm are nonmotile.
d. A young child dies because her cells lack an enzyme that normally breaks down a membrane glycolipid that therefore accumulated in the membranes of her nervous system.
e. A young child is placed on a milk-free diet because the mucosal cells that line his small intestine do not secrete the enzyme necessary to hydrolyze lactose, the disaccharide present in milk.
Answer:
a. mitochondria, underactive
b. peroxisome, underactive
c. flagella, underactive
d. lysosome, underactive
e. Endoplasmic reticulum/Golgi apparatus/transport vesicles, underactive
Explanation:
Cyanide is a toxic compound that inhibits the Cytochrome c Oxidase I (COI) in mitochondria, which is an enzyme known to catalyze the final step in the mitochondrial electron transfer chain. Adrenoleukodystrophy is an X-linked genetic disease caused by a mutation in the ABCD1 gene (ATP-binding cassette, subfamily D, member 1). ABCD1 encodes the adrenoleukodystrophy protein (ALDP), which is involved in the transport of long-chain fatty acids into peroxisomes. Flagella are cellular structures composed of proteins (microtubules) specialized to carry the male's DNA to the egg cell, i.e., they are responsible for sperm motility. Lysosomal storage disorders (LSDs) represent a group of inherited diseases caused by mutations capable of altering lysosome functions. LSDs are especially associated with defective (abnormal) lysosomal enzymes that are unable to degrade macromolecules such as, in this case, a membrane glycolipid. Finally, lactase is an enzyme produced in small intestine cells. Within these cells, the signal sequence of the preprolactase precursor is cleaved in the endoplasmic reticulum (ER). Subsequently, the protein precursor travels to the Golgi complex for processing (i.e., glycosylation), thereby a mature enzyme (lactase) is generated.

Gallardo and Araneda (1994) studied populations of the rodent, Ctenomys maulinus, before and after an eruption of a volcano in the Andes. Survival was random, and the rodent populations after the eruption were only a small fraction of the size of populations before the eruption. Which of the following is likely to be TRUE of the surviving populations relative to the populations before the eruption?
a) Remaining populations will have reduced genetic diversity
b) Adaptive alleles have decreased in frequency
c) All of the answer choices are possible outcomes in this scenario.
d) Maladaptive alleles have increased in frequency
Answer:
A) Remaining populations will have reduced genetic diversity
Explanation:
A random mating population allows for genetic diversity as each individual have equal chance of been mated to and it allows for perpetuation of frequently occurring genes.
For a small population the frequency of allele is mostly fix with virtually all loci having the same genotype because mating is within small individual and genes whose frequency is few will be drifted out of the population.
Hence, after the eruption due to a small random population diversity will be reduced as diversity occur more in a large random mating population.

A student prepares a cell homogenate from spinach leaves. She performs a cell fractionation experiment to determine the shortest amount time of centrifugation at 2000xg that will yield the highest percentage of chloroplasts in the pellet fraction. She splits the spinach homogenate into 5 equal parts and centrifuges the parts at 2000xg for 0, 5, 10, 15 or 20 min. She then determines the proportion of chloroplasts in the supernatant and pellet fractions. The controlled variable(s) in the student's experiment is/are:_____.
a. proportion of chloroplasts in each fraction.
b. use of same plant homogenate throughout.
c. time of centrifugation in minutes.
d. g-force of centrifugation.
Answer:
b. use of same plant homogenate throughout.
Explanation:
In an experiment, the controlled variable, also called the CONSTANT is the variable that is kept the same throughout the course of the experiment in order not to influence the result or outcome of the experiment.
In this question, a student performs a cell fractionation experiment to determine the shortest amount time of centrifugation (manipulated variable) at 2000xg that will yield the highest percentage of chloroplasts (responding variable) in the pellet fraction. In this experiment, the variable being controlled is same spinach plant homogenate used throughout.
In the homeostasis lab we are using ____________________ as a homeostatic parameter.
Answer:
Body temperature
Explanation:
Homeostasis is the a resistance to change due to the body's attempt to maintain constant and stable internal environment. To maintain the body's overall functioning it is very important that homeostasis is maintained at all levels.
Body temperature can be used as homeostasis parameter in the lab. It is important that that the body tries to maintain a constant temperature.

If the boundary between two plates is divergent, it means that the relative motion of the plates at the boundary is ____________.
a. sliding past each other
b. towards each other
c. away from each other
d. none of the above
Answer:
Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest.
In rabbits, an allelic series helps to determine coat color at the color C locus: C (full color), cch(chinchilla; gray color), ch (Himalayan; white with black extremities), and c (albino; all white). The C allele is dominant to all others, cch is dominant to ch and c, ch is dominant to c, and c is recessive to all the other alleles. What types of progeny would you predict from a cross of Cch x cch
Answer:
1 Full color : 1 Himalayan
Explanation:
This question is depicting the multiple allele phenomenon in rabbits where four different alleles are responsible for coat color. The alleles are:
- C codes for full color
- cch codes for chinchilla; gray color
- ch codes for Himalayan; white with black extremities, and
- c codes for albino; all white
However, according to the question, the order of dominance of these alleles is: C > cch > ch > c. Hence, in a cross between Cch x chc, the following gametes will be produced by each parent:
Cch - C and ch
chc - ch and c
Using these gametes in a punnet square (see attached image), the following genotypic proportion of offsprings will be produced;
Cc = full color
Cch = full color
chc = Himalayan (white with black extremities)
chch = Himalayan (white with black extremities)
Hence, full color and Himalayan are the types of progeny that will be predicted from the cross.
Two pea plants with purple flowers are crossed. Among the offspring, 63 have purple flowers, and 17 have white flowers. With a chi-square test, compare the observed numbers with a 3:1 ratio and determine if the the difference between observed and expected is statistically significant. Note: Chi-square critical value with 1 degree of freedom is 3.84 with alpha equal to 0.05
Answer:
Chi-square value = 0.6
The difference between the observed individuals and the expected individuals is not statistically significant. There is not enough evidence to reject the null hypothesis.
Explanation:
H₀= Individuals will be equally distributed
H₁ = Individuals will not be equally distributed.
• Chi square= ∑ ((O-E)²/E)
∑ is the sum of the terms
O are the Observed individuals
E are the Expected individuals
• Freedom degrees = 1
• Significance level, 5% = 0.05
• Table value/Critical value = 3.84
The number of observed individuals:
63 have purple flowers, 17 have white flowersTotal number of individuals, N = 80 = 63 + 17
Observed Genotypic frequencies:
F(PF) = 63/80 = 0.79F(pf) = 17/80 = 0.21p² + 2pq + q² = 1
p² + 2pq = F(PF)
0.79 + 0.21 = 1
The expected genotypic frequency:
F (PF)= 0.75
F (pf) = 0.25
The number of expected individuals:
PF= 0.75 x 80 = 60 wf = 0.25 x 80 = 20Chi square = sum (O-E)²/E
PF = (O-E)² /EPF =(63 - 60) ² / 60
PF = 0.15
pf = (O-E)² /Epf= (17 - 20)²/20
pf= 0.45
Chi square= sum ((O-E)²/E) = 0.15 + 0.45 = 0.60
Chi square = 0.6Degrees of freedom = 1 alpha 0.05 Table value/Critical value = 3.840.6 < 3.84 meaning that the difference between the observed individuals and the expected individuals is not statistically significant. There is not enough evidence to reject the null hypothesis. Probably both parentals were heterozygous for the trait.
