In humans, brown eyes (B) is dominant over blue eyes (b). Teddy has brown eyes, his mother has brown eyes and his father has blue eyes. Their punnett square is represented in the picture attached:
Teddy says that all 4 children in his family have brown eyes. Is this possible?
Question 12 options:
a. Yes, because every child has a 50% chance of having brown eyes
b. No, they should be half brown eyes and half blue eyes
c. No, at least one of his siblings should have brown eyes
Answers
Answer:
A. Yes, because every child has a 50% chance of having brown eyes
Explanation:
This is the correct answer
According to the Punnett square that is given below, the argument made by Teddy may not have correct evidence. This is because it is not possible to have all 4 children in his family has brown eyes. So, the correct option for this question is B.
What is Punnett square?A Punnett square may be characterized as a type of table in which all of the plausible consequences for a genetic cross between two individuals with known genotypes are given.
According to the context of this question, the genotype of the mother is Bb which has a brown phenotype because brown eye (B) is dominant over blue eyes (b). While the genotype of the father is bb. This is blue eyes.
When both these genotypes are crossed, the genotypes of offspring are Bb, Bb, bb, and bb. This means that the individuals have both traits of blue and brown phenotypes by 50% each.
Therefore, the correct option for this question is B.

Chemical weathering occurs by which of the following:
heat
oxidation
hydrolysis
dissolution
water
wind
Answers
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.

Answers
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.

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.

The right answer is option a (Buckminster fullerene).
Fullerene is one of the crystalline allotrope of carbon, which was discovered in 1985 collectively by the scientists Richard E. Smalley, Robert F. Curl, Sean O' Brien, James Heath and Harold Kroto. The name 'buckminsterfullerene' was given to the fullerene molecule discovered as a homage to the American architect and scientist Buckminster Fuller.
