Do biological systems contradict the second law of thermodynamics? by taking energy from their surroundings and synthesizing lar

Bogdan [553]

Biological systems do not contradict the second law of thermodynamics. Even in this case, entropy is still always increasing. Biological systems can only decrease their own entropy by using copious amounts of energy and by increasing entropy in their surrounding environment. Also, unfavorable anabolism reactions are always paired with more favorable reactions, such as the use of ATP in order to make the overall Gibb's free energy of the reaction negative.

n cattle, an autosomal mutation called Dexter produces calves with short stature and short limbs. Embryos that are homozygous fo

timofeeve [1]

Answer:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Explanation:

Dexter is deleterious in homozygous condition, hence, phenotypes are heterozygous.

Roan are also heterozygous.

If dexter allele is represented by D, non dexter individuals will be DD dexter individuals will have the genotype Dd.

If colour in cattle is represented by R, red individuals will be RR, white will be rr, then roan colour will be Rr.

Hence, roan dexter cow and roan dexter bull will both have DdRr genotypes.

Crossing the two: DdRr x DdRr

Progeny:

1 DDRR - Red, non-dexter

2 DDRr - Roan, non-dexter

2 DdRR - Red, dexter

4 DdRr - Roan, dexter

1 DDrr - white, non-dexter

2 Ddrr - white, dexter

Others that are either aborted or stillbirths include:

1 ddRR

2 ddRr

1 ddrr

List the terrestrial planets. Recount the goldilocks theory with respect to these planets

mars1129 [50]

The terrestrial planets are Mercury, Venus, Earth, and Mars.

Here's the explanation in regards to the Goldilocks Theory.

The Goldilocks Theory is often used by astrologists to describe the conditions of Earth's positioning in the solar system. The Goldilocks Zone was described by Stephen Hawking as "like Goldilocks, the development of intelligent life requires that planetary temperatures be ‘just right’” The Goldilocks theory argues that a planet must be neither too far away from nor too close to a star and galactic center to support life, while either extreme would result in a planet incapable of supporting life. Terrestrial planets such as Mercury, Venus, Earth, and Mars are more likely to lie in the Goldilocks zone due to their close proximity to their home star along with other crucial factors that allow for life to exist.
