Answer the following question given this paragraph: After fertilization, the zygote divides to form two cells: the upper cell, or terminal cell, and the lower, or basal, cell. The division of the basal cell gives rise to the suspensor, which eventually makes connection with the maternal tissue. The suspensor provides a route for nutrition to be transported from the mother plant to the growing embryo. The terminal cell also divides, giving rise to a globular-shaped proembryo (Figure 32.19a). In dicots (eudicots), the developing embryo has a heart shape, due to the presence of the two rudimentary cotyledons (Figure 32.19b). In non-endospermic dicots, such as Capsella bursa, the endosperm develops initially, but is then digested, and the food reserves are moved into the two cotyledons. As the embryo and cotyledons enlarge, they run out of room inside the developing seed, and are forced to bend (Figure 32.19c). Ultimately, the embryo and cotyledons fill the seed (Figure 32.19d), and the seed is ready for dispersal. Embryonic development is suspended after some time, and growth is resumed only when the seed germinates. The developing seedling will rely on the food reserves stored in the cotyledons until the first set of leaves begin photosynthesis. Q: After fertilization, how many cells does a zygote form into? Choices: - three - one - six - two A:
(Answer)
two
Ques: Answer the following question given this paragraph: Another example of habituation is shown below ( Figure below ). Crows and most other birds are usually afraid of people. They avoid coming close to people, or they fly away when people come near them. The crows landing on this scarecrow have become used to a "human" in this place. They have learned that the scarecrow poses no danger. They are no longer afraid to come close. They have become habituated to the scarecrow. Q: A crow that becomes used to a scarecrow and lands on it is an example of what? Choices: - assimilation - adaptation - dissociation - habituation A:
Ans: habituation

Answer the following question given this paragraph: Animal behavior is any way that an animal interact with other animals or the environment. An animal may carry out behaviors alone or with other animals. The photos in Figure below show just a few of the ways that animals behave. Look at the pictures and read about the behaviors they represent. Why do you think the animals are behaving in these ways? And how do the behaviors come about? Which, if any of them, have to be learned?. Q: What is the term for any way that an animal interacts with other animals or the environment? Choices: - animal biology - animal way - immunity - animal behavior A:
(A).
animal behavior
Ques:Answer the following question given this paragraph: Transpiration is like evaporation because it changes liquid water to water vapor. In transpiration, plants release water vapor through their leaves. This water vapor rises into the atmosphere. Q: What is it called when plants release water vapor through their leaves? Choices: - propagation - evaporation - respiration - transpiration A:

Ans:transpiration
Answer the following question given this paragraph: An electric field is a space around a charged particle where the particle exerts electric force on other charged particles. Because of their force fields, charged particles can exert force on each other without actually touching. Electric fields are generally represented by arrows, as you can see in the Figure below . The arrows show the direction of electric force around a positive particle and a negative particle.

Q: What do you call the space around a charged particle where the particle exerts electric force on other charged particles? Choices: - melodic field - powered field - charged field - electric field A:
electric field
