When Quorn® was first marketed it was described as being 'mushroom in origin' What does this mean?
Answer:
Explanation:
Though until recently the manufacturer's (Marlow Foods) advertising and labeling implied that the product is “mushroom protein” or “mushroom in origin,” the mold (or fungus) from which it is made does not have much to do with mushrooms. Rather, the mold is grown in liquid solution in large tanks

2: Water is a good solvent- Explain what that means.
Answer:
Water is capable of dissolving a variety of different substances, which is why it is such a good solvent. And, water is called the "universal solvent" because it dissolves more substances than any other liquid. ... This allows the water molecule to become attracted to many other different types of molecules

water is in the beaker. Eventually, the water becomes hot and boils. The
liquid water changes to water vapor. In what way is the liquid water
different from the water vapor? *
OO
The liquid particles move slower.
The liquid has a higher boiling point.
The vapor has a lower temperature.

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
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.

Phillip Gingrich finds an S-shaped bone in this partial skull, a sigmoid process, which is unique to
one particular order of animals in the water today... which one?
Answer:
A primitive whale which he named Pakicetus.
Explanation:
Philip Gingrich is a vertebrate paleontologist at the University of Michigan. He has performed extensive research on whales at the Egyptian desert of Wadi Hitan. His research team member discovered a skull whose braincase was bigger than that of a walnut. Gingerich was able to link the small-brained animal, to an early whale.
The auditory bulla had an s-shaped bony crest known as the sigmoid process and these two features helped whales to hear in water. The case, however lacked other features that helped whales hear beneath the waves. This led Gingrich to the conclusion that the unknown animal was semi-aquatic. This finding also lent credence to the possibility of whales evolving from terrestrial animals.

Explanation:
explain how temperature affects population size
Answer: High temperature and drying were both associated with greater per capita mortality rate. Smaller population sizes at high temperatures and drying regimes may result from increased desiccation of adults and thus higher mortality. These precipitation effects on adult production are absent at 22°C
OR
Other than toxic metals, temperature rise and low resource availability are factors that are also known to stress populations. A rise in temperature generally accelerates metabolic rates and hence population growth rate
Rr x Rr what percent of the offspring will be round
Answer:
75%
Explanation:
The allele for the dominant round phenotype is represented by R while the allele for recessive wrinkled phenotype is represented by r. In this question, two heterozygous parents are crossed i.e. Rr × Rr.
These parents will produce gametes as follows: R and r. Using these gametes in a punnet square (see attached image), the following offsprings will be produced: RR, Rr, Rr and rr. The RR, Rr, Rr offsprings will have a round phenotype while the rr will have a wrinkled phenotype. This means that 3/4 × 100 = 75% of the offsprings will be round.
