Chickens can have different types of feathers. frizzled feathers curl toward a chicken’s head. assume that feather type is determined by a single gene and that the allele for frizzled feathers is dominant over the allele for straight feathers. in a cross between two chickens with straight feathers, what percentage of the offspring can be expected to have frizzled feathers? *
a. 0%
b. 25%
c. 50%
d. 100%
2. atmospheric nitrogen has to be combined with other elements, or fixed, in order to be used by plants. lightning is one way that nitrogen is fixed. when lightning occurs, the extreme heat breaks the bonds in nitrogen molecules, allowing nitrogen to combine with oxygen and form nitrogen oxides. in what way is most of the nitrogen fixed by lightning made available for use by plants?
a. it is moved by the wind toward dry areas.
b. it is incorporated into the exoskeletons of flying insects that eat plants.
c. it is inhaled and exhaled by birds roosting in trees during rainstorms.
d. it is carried by rain to the soil.

Schools are being forced to embrace computers. unlike their "digital immigrant" teachers, these students are "digital natives", born into a world where technology is an integral part of everyday life. almost every student has access to a multitude of computers, laptops and tablet devices. it would be crazy to assume an assignment would  notbe written on computer in this day and age.many schools now have a 1-to-1 computer policy, and many districts and states in the united states have mandated computers or ipads across the state for every student,  including los angeles, the second largest school district in the country.but the thing is, when they tried it in la, it wasn't the success they hoped for. that's because the tablets weren't used as much as they expected. rather, it appeared there was a gap between the digital native's love of technology and their use of it in the classroom.this conflicted relationship with computers is also underscored by much of the literature on education. it is also highlighted in professional development and conferences such as  edutech.

Where are the options?
