What are some of the posible signals of male quality in widowbirds and what information might they convey? What are the females choosing and why
Male produces signals of bright red, yellow epaulets and long tails.
Males produce bright red and yellow epaulets as well as chevrons on their wings. These bright epaulets attracts the female of this species and helps in the sexual activity of widowbird species.
The males of several widowbird species also grow long tail feathers about half a meter in length. The long tail is favored by sexual selection through female choice of mates. Female prefer long tails red-collared widowbird so we can conclude that male produces signals of bright red, yellow epaulets and long tails.

I hope 4 is the ans.... coz the breaking of high energy bonds btw phosphates releases energy
Two phosphoanhydride bonds, which have high energy, connect these three phosphate groups, hence c and d store energy within the molecule.
How does energy store in an ATP molecule?An adenine base is joined to a ribose sugar, which is joined to three phosphate groups, to form the nucleotide ATP. Two phosphoanhydride bonds, which have high energy, connect these three phosphate groups.
At the cellular level, energy is used and stored as adenosine triphosphate (ATP). Adenine, ribose sugar, and three serially bound phosphate groups make up the structure of ATP, which is a nucleoside triphosphate.
Therefore, the structure of ATP is a nucleoside triphosphate having Two phosphoanhydride bonds, hence c and d store energy within the molecule.

Students observe several slides of tissue cross-sections under the microscope. They are asked to develop a key system to classify the slides as coming from either monocot or dicots. What key system should the students develop
As students observe several slides of tissue cross-sections, one simple key they can use to determine if the slides come from dicots or monocots is to analyze the vascular bundles.
A vascular bundle is described as a portion of the transport system of vascular plants. These bundles are microscopically different in Monocots than they are in Dicots, which will allow students to tell them apart through the tissue slides.
The difference is that monocots contain randomly scattered bundles located throughout the stem. On the other hand, dicots have their vascular bundles more neatly organized in concentric circles. These microscopic differences can serve as a key to be used by the students to classify the tissue samples they are studying.
