Frogs, lizards, and birds all have simular arrangment of bones n thier limbs. BOth thier arms and legs have one bone at the top, two bones at the bottom, little bones and then fingers or toes. What does the similarity o the bone struture suggest about these animals?
A. They have a common ancestar
B. They are comparable in size as adults
C. They evolved at the same time
D. They move in the same way
The similarity of the bone structure suggest about these animals should be that they evolved at the same time
What is bone structure?Bones are considered to be the living tissue that comprise of the own blood vessels, and should be made of the various cell, proteins, minerals, etc. In this it enables them for growing, transformation, and repair via the life.
Since both arm and legs should have one bone at the top, so here we considered the option c should be right.

Tonicity in cells refers to the concentration of solute in a solution outside the cell relative to______.
Tonicity in cells depends on both the concentration of solute outside the cell and the concentration of solute inside the cell
Tonicity is a concept used in biology that defines the osmotic pressure ( pressure that stops the fluids from entering or leaving cells). This pressure is defined by the concentration of solute (substances dissolved in the liquid) outside and inside the cell.
In this context, the cell is classified as isotonic if there is a balance between the concentration outside and inside; hypertonic if the concentration outside the cell is higher, which causes the cell to shrink of hipotonic if the concentration outside is lower, which causes the cell to swell.

What are two different characteristics of living things shown by a corn plant?
Answer and Explanation:
The corn plant shows 2 different characters of living by the color of the stock and the corn, and if the corn is big.
This may not be true for all things, so another 2 characteristics may be if the corn stock is growing tall, and that the corn stock does really good when given enough food (soil) and water.

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.

Unit 4 Cell Transport: What are three major molecules that enter the cell?
Answer:
Water, carbon dioxide, and oxygen can enter the cell.
Explanation:
They can enter the cell because they are small and can use osmosis to enter the cell.
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.

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.

Which location has the warmer air temperature: Tarapoto or Lima? Why?
view pic below.
Answer:The location that is has warmer air temperature is Tarapoto Peru because the lower it goes the more colder the temperature.
Explanation:Tarapoto in Peru has a warmer air temperature than Lima because the ocean currents is passing the coast of lima and the currents are coming from the pole and Tarapoto does not depend on the ocean currents and It is near the equator so Tarapoto has a warmer air temperature.
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.

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.
Our current paradigm on the position of continents in the World is that they have always been located where they are now.
