I need help! What is an idea of a proposal of a device that minimizes heat transfer?

Irina-Kira [14]

Engineers must understand the thermal properties of materials to be able to predict the performance of any given material over its lifetime in a specific application. Engineers apply their understanding of the thermal properties of materials to the design of efficient heat transfer materials for better engines, spacecraft and electronic devices. They also examine the thermal properties of insulation to design more efficient buildings and homes. Engineers develop ways to minimize heat transfer from a motor to the surrounding environment. Often they find ways to insulate the motor to decrease the convective heat transfer from the motor. They design a refrigerator to keep heat out of the inside, as well as keep the refrigerator contents cool. hope this helped

In corn, red kernel color (R) is dominant to yellow (r) and smooth kernel texture (W) is dominant to wrinkled (w).

Wewaii [24]

Answer:

a. df = 3, chi-square = 1.7333, p value = 7.815

b. we fail to reject null hypothesis

c. it is independent of kernel texture

Explanation:

h0; there is independence

h1; no independence

9:3:3:1 this is the phenotypic ratio

9+3+3+1 = 16

330 red smooth + 97 red wrinkled + 101 yellow smooth + 32 yellow wrinkled

total observed = 560

1. the degree of freedom = n-1

n =4, 4-1 = 3

to get the chi square computation

(O-E)²/E

expected value for red smooth,

9/16 x 560 = 315

chisquare = (330-315)²/315 = 0.7143

expected for red wrinkled

3/16*560 = 105

chisquare = (97-105)²/105 = 0.6095

expected for yellow smooth

3/16*560 = 105

chisquare = (101-105)²/105 = 0.1524

expected for yelow wrinkled

1/16 * 560 = 35

chisquare = (32-35)²/35 = 0.2571

total chisquare = 0.7143+0.6095+0.1524+0.2571

= 1.7333

with probability = 0.05, df = 3, the value of the chi square from x² table = 7.815

1.7333 < 7.815

so we fail to reject the null

c. we conclude that kernel color is independent of kernel texture

A sexually reproducing animal has two unlinked genes (on separate chromosomes), one for head shape (H) and one for tail length (

Verizon [17]

Answer:

a) HT

Explanation:

This question shows an animal with two distinct unlinked genes i.e. on different chromosomes. One gene codes for head shape and the other for tail length. The gene for head shape possess alleles H and h, while gene for tail length possess alleles T and t.

According to Mendel's law of independent assortment, the alleles of a gene will separate into gametes independently of the alleles of another gene. This occurs in such a way that each gamete will contain only one allele from a gene.

Based on this principle, an animal with genotype HhTt will undergo meiosis and randomly produce gametes with the following allelic combinations: HT, Ht, hT, and ht. As seen in the gametes, only one allele of a gene occured in a gamete at a time.

Therefore, HT is the genotype possible in a gamete of parent: HhTt.
