Question: Q: When does sublimation occur?   Read this paragraph and choose the correct option from the provided answers:  Sublimation occurs when ice and snow change directly to water vapor. This also happens because of heat from the sun.   Choices:  - when the wind changes direction  - when the snow melts the ice caps  - when the ice and sand change directly into water vapors  - when the ice and snow change directly into water vapors   A:
when the ice and snow change directly into water vapors

Q: The chloroplasts contained within the green algal endosymbionts still are capable of what process associated with plants?   Read this paragraph and choose the correct option from the provided answers:  Several lines of evidence support that chlorarachniophytes evolved from secondary endosymbiosis. The chloroplasts contained within the green algal endosymbionts still are capable of photosynthesis, making chlorarachniophytes photosynthetic. The green algal endosymbiont also exhibits a stunted vestigial nucleus. In fact, it appears that chlorarachniophytes are the products of an evolutionarily recent secondary endosymbiotic event. The plastids of chlorarachniophytes are surrounded by four membranes: The first two correspond to the inner and outer membranes of the photosynthetic cyanobacterium, the third corresponds to the green alga, and the fourth corresponds to the vacuole that surrounded the green alga when it was engulfed by the chlorarachniophyte ancestor. In other lineages that involved secondary endosymbiosis, only three membranes can be identified around plastids. This is currently rectified as a sequential loss of a membrane during the course of evolution. The process of secondary endosymbiosis is not unique to chlorarachniophytes. In fact, secondary endosymbiosis of green algae also led to euglenid protists, whereas secondary endosymbiosis of red algae led to the evolution of dinoflagellates, apicomplexans, and stramenopiles.   Choices:  - germination  - respiration  - reproduction  - photosynthesis   A:
(Answer)
photosynthesis

Q: What property of an object is obtained by multiplying its mass and its velocity?   Read this paragraph and choose the correct option from the provided answers:  When skater 2 runs into skater 1, he’s going faster than skater 1 so he has more momentum. Momentum is a property of a moving object that makes it hard to stop. It’s a product of the object’s mass and velocity. At the moment of the collision, skater 2 transfers some of his momentum to skater 1, who shoots forward when skater 2 runs into him. Whenever an action and reaction such as this occur, momentum is transferred from one object to the other. However, the combined momentum of the objects remains the same. In other words, momentum is conserved. This is the law of conservation of momentum .   Choices:  - fluid  - component  - movement  - momentum   A:
(A).
momentum
