Answer:
c
Explanation:
During Precambrian time, The amount of oxygen increased in the earth's atmosphere. Therefore, option C is correct.
What is the Precambrian time period?From roughly 4.6 billion years ago, when Earth first started to form, to the start of the Cambrian Period, 541 million years ago, is the Precambrian Period. It is the earliest era which is followed by the Cambrian period.
Large objects bombarded the Precambrian Earth, the crust was split into the first continents and ocean basins, crustal plates were mobilized, the atmosphere changed from reducing to oxidizing, and early life began and evolved. Climate and geologic events are responsible for the end of this period.
During this period, the amount of oxygen increased rapidly. Therefore, option C is correct.

How is antibiotic resistance related to natural selection?
Answer:
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

4. Why does sexual reproduction result in offspring with genetic variation? Use the examples that you studied to support your answer.
Answer:
Sexual reproduction results in offsrping with genetic variation due to the multiplication brings about limitless prospects of hereditary variety. The examples, that can be studied to support this would be at the end of the day, sexual generation brings about posterity that are hereditarily extraordinary. They vary from the two guardians and furthermore from one another. This happens for various reasons.
Explanation:
Sexual reproduction results in offspring with genetic variation because it involves the fusion of genetic material from two parent organisms, typically a male and a female.
What is genetic variation?Genetic variation refers to the diversity of genetic traits or characteristics within a population or species.
The process introduces genetic diversity through several mechanisms in
Independent Assortment, Crossing Over, Genetic Recombination,
Mutations.
Overall, sexual reproduction promotes genetic variation by combining genetic material from two parents through mechanisms such as independent assortment, crossing over, genetic recombination, and the introduction of new mutations.
This variation is essential for the survival and adaptation of populations to changing environments and plays a fundamental role in evolution.

Chemical weathering occurs by which of the following:
heat
oxidation
hydrolysis
dissolution
water
wind
Solution, carbonation, hydration, oxidation, and reduction are significant chemical weathering reactions, hence options B and C are correct.
What is chemical weathering?Chemical weathering is the term used to explain how chemicals in rainfall alter the minerals in a rock. Rainwater becomes somewhat acidic as a result of the air's carbon dioxide being dissolved in it.
Weathering can result from an interaction between the minerals in the rock and precipitation.
Oxidation, hydrolysis, and carbonation are processes that take place during chemical weathering.
Therefore, hydrolysis is a reaction with water, carbonation is a reaction with CO₂ to generate a carbonate, and oxidation is a reaction with oxygen to form an oxide, hence options B and C are correct.

Humans lived with domesticated dogs over thousands of years which resulted in many breeds of dogs. Humans bred some dogs to have thick
coats to keep the dogs warm in cold climates while other dogs have thin coats that live in warm climates.
Which evidence supports the claim that dogs inherit these characteristics?
O
A. During mitosis, mutations occurred and the offspring's DNA stored this information
B. As dogs digested food, mutations occurred which changed the dog's physical appearance.
O C. Since dogs lived closely in contact with humans, the dog's genetic information remained the same.
D. During meiosis, new combinations of genetic information occurred, and the offspring's genes expressed this information.
Answer:
Did humans tame woolly mammoths or other megafauna?
Considering that some people are gifted with handling animals (e.g. horse whisperers), could paleoindians or other Pleistocene peoples have gained the confidence of woolly mammoths or mastodons to use them as transportation and other tasks, the way that Asian elephants are used today?
Fewer resources would be necessary for a human to travel long distances by riding on the back of a woolly mammoth or paleocamel, as the megafauna could graze and get energy. People may also have traveled by boat during late Pleistocene times (the kelp highway along PNW).
How could we test such a hypothesis? Cave art showing a rider on the back of one of the megafauna? A bridle and/or bit? A talisman worn by a camel is known to have been crafted from a meteorite(1), and so talismans or decorations might have adorned the hypothesized woolly steed. Metal was not a known technology during stone tool usage, as far as we know, though.
Green seed color (G) is dominant over yellow seed color (g). If two heterozygous parents are crossed, what are the resulting phenotypes expressed as a percent?
A) 50% green, 50% yellow
B) 75% green, 25% yellow
C) 50% GG, 50% gg
D) 25% GG, 50% Gg, 25% gg
E) none of the above
Answer:
B) 75% green, 25% yellow
Explanation:
There are three genotypes made from crossing two heterozygous parents (Gg);
GG
Gg
gg
Crossing two heterozygous parents (Gg) results in 50% Gg, 25% GG and 25% gg. Since green (G) is dominant over yellow (g), there would be a total of 75% green and 25% yellow.

Explanation:
The number of copies of an allele in a population divided by the total number of all alleles for that gene in a population is the allele frequency. For a gene with two alleles whose frequencies are p and q, the Hardy-Weinberg equation states that the genotypes that are possible for the population are p^2 + 2pq + q^2, which is equal to
