user: Answer the following question given this paragraph:   The daughter cells then start to divide by meiosis . But they only go through the first of the two cell divisions of meiosis at that time. They go through the second stage of cell division after the female goes through puberty.   Q: Daughter cells divide by what?   Choices:  - electrolysis  - mitosis  - nucleus  - meiosis  A:
meiosis


(Question)
Answer the following question given this paragraph:   A lichen is a mutualistic relationship between a fungus and a photosynthetic organism. The other organism is usually a cyanobacterium or green alga. The fungus grows around the bacterial or algal cells. The fungus benefits from the constant supply of food produced by the photosynthesizer. The photosynthesizer benefits from the water and nutrients absorbed by the fungus. Figure below shows lichen growing on a rock.   Q: The fungus benefits from the constant supply of food produced by what?   Choices:  - the host  - the spermatophyte  - the phytoflagellate  - the photosynthesizer  A:
(Answer)
the photosynthesizer


Ques: Answer the following question given this paragraph:   Mammals conserve heat with their hair or fur. It works like the layer of insulation in the walls of a house. It traps warm air next to the skin so it can’t escape into the environment. Like the squirrel in Figure below , most mammals can make their hair or fur stand up from the skin. This makes it a better insulator. Mammals also have a layer of insulating fat beneath their skin. Other vertebrates lack this layer of fat.   Q: What do mammals conserve heat with?   Choices:  - fur or muscle  - skin or bones  - tendons or hair  - hair or fur  A:
Ans: hair or fur


(Q).
Answer the following question given this paragraph:   Electric current occurs whenever there is a difference in electric potential energy, or voltage. Voltage is measured in volts (V).   Q: What is the unit used to measure voltage?   Choices:  - watt  - ampere  - ohm  - volts  A:
(A).
volts


Ques:Answer the following question given this paragraph:   Fishes Modern fishes include an estimated 31,000 species. Fishes were the earliest vertebrates, and jawless fishes were the earliest of these. Jawless fishes—the present day hagfishes and lampreys—have a distinct cranium and complex sense organs including eyes, distinguishing them from the invertebrate chordates. The jawed fishes evolved later and are extraordinarily diverse today. Fishes are active feeders, rather than sessile, suspension feeders. Jawless Fishes Jawless fishes are craniates (which includes all the chordate groups except the tunicates and lancelets) that represent an ancient vertebrate lineage that arose over one half-billion years ago. Some of the earliest jawless fishes were the ostracoderms (which translates as “shell-skin”). Ostracoderms, now extinct, were vertebrate fishes encased in bony armor, unlike present-day jawless fishes, which lack bone in their scales. The clade Myxini includes 67 species of hagfishes. Hagfishes are eel-like scavengers that live on the ocean floor and feed on dead invertebrates, other fishes, and marine mammals (Figure 15.37a). Hagfishes are entirely marine and are found in oceans around the world except for the polar regions. A unique feature of these animals is the slime glands beneath the skin that are able to release an extraordinary amount of mucus through surface pores. This mucus may allow the hagfish to escape from the grip of predators. Hagfish are known to enter the bodies of dead or dying organisms to devour them from the inside.   Q: Fishes were the earliest example of what subphylum, and jawless fishes were the earliest of these?   Choices:  - grasses  - ferns  - mammals  - vertebrates  A:

Ans:vertebrates


Question: Answer the following question given this paragraph:   Lifecycle of Leukocytes Most leukocytes have a relatively short lifespan, typically measured in hours or days. Production of all leukocytes begins in the bone marrow under the influence of CSFs and interleukins. Secondary production and maturation of lymphocytes occurs in specific regions of lymphatic tissue known as germinal centers. Lymphocytes are fully capable of mitosis and may produce clones of cells with identical properties. This capacity enables an individual to maintain immunity throughout life to many threats that have been encountered in the past.   Q: Characterized by a short lifespan, what begin with production in the bone marrow under the influence of csfs and interleukins?   Choices:  - solutes  - pathogens  - erythrocytes  - leukocytes  A:
Answer:

assistant: leukocytes
