Answer:

d. polarity

Explanation:

Water is considered as the universal solvent because it is able to dissolve the most substances compared to any other liquid. It's polarity is what makes it so capable.

The molecular arrangement of the hydrogen and oxygen molecules in water allows it to attract different substances. The hydrogen side is positive, while the oxygen side is negative in terms of charge. When substances go near it, it is able to disrupt the bonds that the molecule is holding them together.

Large amounts of oxygen gas first appeared in earth's atmosphere about ______ years ago. 500,000 3.5 million 10 million 2.7 bill

Lostsunrise [7]

Answer:

2.7 billion

Explanation:

This period is referred to as the Great Oxygenation Event. This period saw the evolution of photosynthetic organisms (cyanobacteria) that utilized carbon dioxide (that dominated the atmosphere then) and sunlight to manufacture their energy molecules-glucose. Photosynthesis produces oxygen as a byproduct that is evolved into the atmosphere. As these photosynthetic organisms proliferated on earth, the atmosphere composition changed to become partly dominated by oxygen (which is an oxidaton agent) with less and less carbon dioxide.

In cats, being awesome (A) is dominant to being average (a), and being bashful (B) is dominant to being

BlackZzzverrR [31]

Answer:

Probability that both cats described will have an offspring who is heterozygous for both traits is 50%, according to the scenario given.

Explanation:

When a cat amazing and bashful is crossed with a cat average and boring, it is a crossing where two traits are taken into account that will be segregated independently by the parents, and the result can be obtained by analyzing their genotypes and making the corresponding crossing in a Punnett square.

Genotypes:

Male cat AABb
Female cat aabb

Crossing :

Punnett's square (simplified)

Alelles AB Ab

ab AaBb Aabb

Offspring:

AaBb amazing and bashful (heterozygous for two traits) 50%
Aabb amazing and boring (heterozygous for trait A ans homozygous recessive for B) 50%

Probability that they will have an offspring who is heterozygous for both traits is 50%.
