input: Dairy cattle

The dairy cow will produce large amounts of milk in its lifetime. Production levels peak at around 40 to 60 days after calving. Production declines steadily afterwards until milking is stopped at about 10 months. The cow is ''dried off'' for about sixty days before calving again. Within a 12 to 14-month inter-calving cycle, the milking period is about 305 days or 10 months long. Among many variables, certain breeds produce more milk than others within a range of around 6,800 to 17,000 kg (15,000 to 37,500 lbs) of milk per year. The Holstein Friesian is the main breed of dairy cattle in Australia, and said to have the ''world's highest'' productivity, at 10000L of milk per year. The average for a single dairy cow in the US in 2007 was 9164.4 kg (20,204 lbs) per year, excluding milk consumed by her calves, whereas the same average value for a single cow in Israel was reported in the Philippine press to be 12,240 kg in 2009. High production cows are more difficult to breed at a two-year interval. Many farms take the view that 24 or even 36 month cycles are more appropriate for this type of cow.

IN: Gene--environment interaction (or genotype--environment interaction or GE) is when two different genotypes respond to environmental variation in different ways. A norm of reaction is a graph that shows the relationship between genes and environmental factors when phenotypic differences are continuous. They can help illustrate GxE interactions. When the norm of reaction is not parallel, as shown in the figure below, there is a gene by environment interaction. This indicates that each genotype responds to environmental variation in a different way. Environmental variation can be physical, chemical, biological, behavior patterns or life events.
is there a relationship between genes and the environment?

Text: Competition speed skydivers fly in a head-down position and can reach speeds of 530 km/h (330 mph; 150 m/s); the current record is held by Felix Baumgartner who jumped from a height of 128,100 feet (39,000 m) and reached 1,357.6 km/h (840 mph; 380 m/s), though he achieved this velocity at high altitude, where extremely thin air presents less drag force.

IN: A stipulation that this kick must be towards the opponents' goal existed in the rules from 1883 until 2016. This resulted in kick-offs typically involving two people (as pictured), with one tapping the ball forward and the other passing it back to the rest of the team. Now a team may kick the ball backwards explaining why the kicker may be in the other half of the field when kicking the ball.
do you have to kick the ball forward at kick off?

OPTIONS:
- no
- yes

OUT:
no
