Correct Answer :   high physiological age

The benefit of lifelong physical activity is prevention of weight gain. Being physically active for a lifelong period usually also makes it gaining weight much harder which in turn makes people leaner at an old age.

Correct Answer :   Oenologist

---

Oenology is the science and study of wine and winemaking. It is distinct from viticulture, which is concerned with the cultivation and harvest of grapes. The English word oenology derives from the word oinos, "wine" (οἶνος) and the suffix –logia, "study of" (-λογία) from the Ancient Greek language. An oenologist is an expert in the field of oenology. Oenology and viticulture are commonly taught together, thus covering all outdoor and indoor aspects of wine and winemaking.

Correct Answer :   Rich in Beta-Carotene

The endosperm of Golden Rice (Oryza sativa) is yellow due to the accumulation of β-carotene (provitamin A) and xanthophylls. The product of the two carotenoid biosynthesis transgenes used in Golden Rice, phytoene synthase (PSY) and the bacterial carotene desaturase (CRTI), is lycopene, which has a red color. The absence of lycopene in Golden Rice shows that the pathway proceeds beyond the transgenic end point and thus that the endogenous pathway must also be acting. By using TaqMan real-time PCR, we show in wild-type rice endosperm the mRNA expression of the relevant carotenoid biosynthetic enzymes encoding phytoene desaturase, ζ-carotene desaturase, carotene cis-trans-isomerase, β-lycopene cyclase, and β-carotene hydroxylase;

only PSY mRNA was virtually absent. We show that the transgenic phenotype is not due to up-regulation of expression of the endogenous rice pathway in response to the transgenes, as was suggested to be the case in tomato (Lycopersicon esculentum) fruit, where CRTI expression resulted in a similar carotenoid phenomenon.

This means that β-carotene and xanthophyll formation in Golden Rice relies on the activity of constitutively expressed intrinsic rice genes (carotene cis-trans-isomerase, α/β-lycopene cyclase, β-carotene hydroxylase). PSY needs to be supplemented and the need for the CrtI transgene in Golden Rice is presumably due to insufficient activity of the phytoene desaturase and/or ζ-carotene desaturase enzyme in endosperm.

The effect of CRTI expression was also investigated in leaves of transgenic rice and Arabidopsis (Arabidopsis thaliana). Here, again, the mRNA levels of intrinsic carotenogenic enzymes remained unaffected; nevertheless, the carotenoid pattern changed, showing a decrease in lutein, while the β-carotene-derived xanthophylls increased. This shift correlated with CRTI-expression and is most likely governed at the enzyme level by lycopene-cis-trans-isomerism.

Correct Answer :   The radius of the earth

---

You could simply lie down on a beach, watch the sun set once, and could quickly stand up once the last bit goes down, to see it go down again. In fact, if you carefully calculate the time difference between these 2 sunsets using a stopwatch, and take the length of your body into account, you could actually calculate (estimate) the radius of the earth.

Correct Answer :   Tamil Nadu

---

The Mudumalai National Park (MNP) is located about 150 kilometres north-west of Coimbatore city in Tamil Nadu. The protected area is home to several endangered and vulnerable species including Indian elephant, Bengal tiger, gaur and Indian leopard. There are at least 266 species of birds in the sanctuary, including critically endangered Indian white-rumped vulture and long-billed vulture.

Correct Answer :   Genes found on chromosomes

---

Genetic alteration probably refers to altering Genes found on chromosomes. Genetic alteration refers to altering DNA sequence. Gene alteration forms genetically modified products that modifies the gene sequence.

Genetic engineering, also called genetic modification or genetic manipulation, is the direct manipulation of an organism's genes using biotechnology.
