At the end of a sunny day, Cindy turns on an electric fan to cool off her room. When she turns off the fan a little later, she notices that the area around the motor is warmer than it was when she turned on the fan. What is the most likely explanation for this?

1.Electrical energy was transformed into heat and energy of motion.


2.Solar energy was transformed into heat and energy of motion.

3.Solar energy was transformed into electrical energy and heat.


4.Electrical energy was transformed into sound and light.

Answers

Answer 1

Answer:

One

Explanation:

Because it never says that the fan used solar energy and 4 wouldn't make it heat up.

Which location has the warmer air temperature: Tarapoto or Lima? Why?
view pic below.

Answers

tarapoto because it is at 0 degrees

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.

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​

Answers

I believe it to be option C

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______.

Answers

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.

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

Answers

A because it’s passing and overlapping caused by the plates

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.

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

Answers

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.

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

Answers

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

Answers

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 flowers

Total number of individuals, N = 80 = 63 + 17

Observed Genotypic frequencies:

F(PF) = 63/80 = 0.79F(pf) = 17/80 = 0.21

p² + 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 = 20

Chi square = sum (O-E)²/E

PF = (O-E)² /E    

PF =(63 - 60) ² / 60

PF = 0.15

pf = (O-E)² /E

pf= (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 = 3.84

0.6 < 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.
