A researcher has two pure breeding strains of fruit flies: strain A and strain B.
Strain A produces only enzyme A and strain B only enzyme B. The alleles
coding for enzyme A and enzyme B are the only alleles involved here and occur at the
same locus. The researcher crossed a fly from strain A with one from strain B and found
that all the offspring (F1 generation) could produce both enzyme A and enzyme B. When he
crossed two of the F1 generation flies, he found the following in the offspring:
658 produced enzyme A, 1364 produced enzyme A and B, 581 produced enzyme B
What type of inheritance can produce these results? Using appropriate symbols, show the
researcher’s cross (up to the F2 generation) What would the expected result be if one of the
offspring that can produce both enzyme A and enzyme B were crossed with one that can only
produce enzyme A (include a Punnett Square)?

A herpetologist finds an anuran which has a green hue. This is the dominant
colour trait and therefore the genotype for colour can be either homozygous
(GG) or heterozygous (Gg). In this species of frog body colour that is brown
suggests a recessive phenotype and therefore this genotype would have to be
homozygous for the recessive allele (gg). G represents the dominant allele and g represents the
recessive allele. Using selective breeding techniques, how would the researcher determine the
genotype of the original green anuran? Explain how the results of this would help the researcher
identify the genotype or the original green anuran.

5. Who seems to be the audience?
Who wants or needs to know this information? Does there seem to be a specific audience the author is trying to reach? Why do you think so? If not, what makes you think there is not a specific audience?
6. What is the overall tone of the work?
What is the author’s general attitude towards their audience? How do the language, content, imagery, and allusions combine to give the reading a ‘feel,’ or tone? What details help you to understand this? What can you infer about the author’s position on important themes or issues because of that tone?
7. What point of view does the author write from?
What point of view was the book written from? What does the author seem to assume is true? Is the author biased in any way? Does the author seem to be aware of this bias? Might it have been done on purpose to further the theme? Is it satirical? Ironic?

Spread across 100 countries and its headquartered in India, Mahindra employs over 2,40,000 people. Tech Mahindra is one of only three Indian companies to be included in the Bloomberg 2020 Gender-Equality Index. They are constantly creating a transparent policy, valuing individual differences. For Tech Mahindra, diversity of every kind is of importance. Be it diversity of one’s nationality or someone’s age, be it about gender, also about thoughts, or their abilities. In fact their constant endeavor is building a workplace that is 'intentionally' varied and diversified in every way possible." a. What are the lessons to be learnt from Tech Mahindra Gender-Equality Index?
b. What practices would you recommend other Indian corporate houses to enable change of diversity and sustain it.
The first divers used metal ‘diving bells’ to move air under the water surface.
(a) Modelling the air in bell as a hemisphere with diameter of 2.5 metres, use the following information to calculate the upthrust produced due to the water.
Ρwater= 997 kgm-3
Volume of a sphere = 4/3𝜋r3
g = 9.81 ms-2
(b) If the bell was fully submerged and then its suspension cable was released, what would its maximum acceleration be, given that its mass was 4500 kg?
