Of the following;

a-erosion

b-volcanic eruption

c-ocean circulation

d-climate

The answer is; B

A volcanic eruption is caused by the energy deep in the earth. The heat from the heats up the ricks into magma that ascends up into the crust through vents and erupts. The differential heating of the earth by the sun is significant in driving ocean circulations and climate too. The uneven heating of rocks causes the rocks to weather.

Plz answer asap - As the universe "Expanded" what happened to the Local Groups of Galaxies?

MakcuM [25]

Answer: In addition to slowing the overall expansion, gravity causes local clumping of matter into stars and galaxies. ... Within the Local Group, the gravitational interactions have changed the inertial patterns of objects such that there is no cosmological expansion taking place.

Answer:

Abrasion is physical weathering caused by water, wind and gravity. The coastal regions are affected by abrasion due to large volumes of water and increased winds. This can become more severe especially with storms that hit coastal regions.

What are the genotypic and phenotypic distributions for the F1 and F2 generations from a cross between a chick with black (BB) f

lord [1]

Answer:

Please find the punnet square to this question as an attachment

F1 generation:

genotype = BW

Phenotype = Erminette offsprings

F2 generation:

genotype = BB (1): BW(2): WW(1)

Phenotype = 1 Black, 2 Erminette, 1White

Explanation:

This question involves a gene coding for feather color in chickens. The allele for black feathers (B) is codominant with the allele for white feathers (W) to form an erminette chicken (black and white speckles).

According to this question, a cross between a chick with black (BB) feathers and chicken with white (WW) feathers will result in an all erminette chicken (BW) in the F1 generation (see attached image)

Also, in the F2 generation got by self-crossing the Erminette genotype in the F1 generation (BW), the following genotypic and phenotypic ratios are observed:

Genotypic ratio = BB (1): BW(2): WW(1)

Phenotypic ratio = 1 Black, 2 Erminette, 1White

In an electrochemical cell, q = 0.0010 and k = 0.10. what can you conclude about ecell and e∘cell? in an electrochemical cell, =

Iteru [2.4K]

If there is electrochemical cell where Q = 0.0010 and K = 0.10 then the truth about Ecell and E°cell is,
Ecell is positive and E°cell is negative.
E° = (RT/nF) InQ = (RT/nF) × In(K/Q) = Positive.
Since ( K/Q) = 100 then In(K/Q) = positive
