A hanging wire made of an alloy of aluminum with diameter 0.11 cm is initially 2.2 m long. When a 34 kg mass is hung from it, th

Lubov Fominskaja [6]

Answer:

Explanation:

Given that d = 0.11cm = 0.0011m, l = 2.2m, extension = 1.24cm = 0.0124m, mass = 34kg

force = 34 x 9.81 = 333.54N, Area = Pi x d²/4 = 3.142 x 0.0011^2/4 = 9.505x10^-7m²

Calculate the stress = Force/Area = 333.54N / 9.505x10^-7m²

= 350926661.4N/m²

calculate the strain = extension/original length

= 0.0124 / 2.2 = 0.00563

Young modulus of elasticity = Stress/Strain = 350926661.4N/m² / 0.00563

= 6.2332 x 10^10Pa

In cats, curled ears result from an allele, Cu, that is dominant over an allele cu, for normal ears. Black color results from an

just olya [345]

Answer:

Explanation:

Cross : ggCuCu X GGcucu --------Parents

F1 progeny : GgCucu

Two of the F1 cats mate :

Cross : GgCucu X GgCucu

Gametes :

Gg X Gg = GG, Gg, Gg, gg

Cucu X Cucu = CuCu, Cucu, Cucu, cucu

1/4 GG X 1/4 CuCu = 1/16 GGCuCu (black - curled ears)

1/4 GG X 2/4 Cucu = 2/16 GGCucu (black - curled ears)

1/4 GG X 1/4 cucu = 1/16 GGcucu (black - normal ears)

2/4 Gg X 1/4 CuCu = 2/16 GgCuCu (black - curled ears)

2/4 Gg X 2/4 Cucu = 4/16 GgCucu (black - curled ears)

2/4 Gg X 1/4 cucu = 2/16 Ggcucu (black - normal ears)

1/4 gg X 1/4 CuCu = 1/16 ggCuCu (gray - curled ears)

1/4 gg X 2/4 Cucu = 2/16 ggCucu (gray - curled ears)

1/4 gg X 1/4 cucu = 1/16 ggcucu (gray - normal ears)

Answer : (i). 9/16 black cats, curled ears; 3/16 black cats, normal ears; 3/16 gray cats, curled ears; and 1/16 gray cats, normal ears.

An F1 cat mates with a stray cat that is gray and possesses normal ears :

Cross : GgCucu X ggcucu

Gametes :

Gg X gg = Gg, Gg, gg, gg

Cucu X cucu = Cucu, Cucu, cucu, cucu

2/4 Gg X 2/4 Cucu = 4/16 GgCucu (black - curled ears)

2/4 Gg X 2/4 cucu = 4/16 Ggcucu (black - normal ears)

2/4 gg X 2/4 Cucu = 4/16 ggCucu (gray - curled ears)

2/4 gg X 2/4 cucu = 4/16 ggcucu (gray - normal ears)

Answer : (i). 1/4 black cats, curled ears; 1/4 black cats, normal ears; 1/4 gray cats, curled ears; 1/4 gray cats, normal ears.

If a gene sequence in one organism is highly similar to the sequence of another gene in another organism it is called

mario62 [17]

Answer:

This question lacks options, options are: a.related. b. homologous. c protein-coding, d. comparative. The correct answer is b.

Explanation:

Homology refers to the fact in which the sequences of two or more proteins or nucleic acids are very similar due to the fact that they have the same evolutionary origin. Normally two sequences have a high similarity because they are homologous, that is, they share a common ancestor. If two sequences in an alignment are from a common ancestor, mismatches can be interpreted as point mutations (substitutions), and gaps as insertion or deletion mutations introduced into one or both lineages in the time since they diverged.
