Answer the following question given this paragraph: Organisms can use different strategies to increase their reproduction rate. Altricial organisms are helpless at birth, and their parents give them a lot of care. This care is often seen in bird species. ( Figure below ). Altricial birds are usually born blind and without feathers. Compared to precocial organisms, altricial organisms have a longer period of development before they reach maturity. Precocial organisms, such as the geese shown below, can take care of themselves at birth and do not require help from their parents ( Figure below ). In order to reproduce as much as possible, altricial and precocial organisms must use very different strategies. Q: What type of organisms are helpless at birth and require lots of help from their parents? Choices: - Microorganisms - multicellular organisms - precocial organisms - altricial organisms A:
altricial organisms

Question: Answer the following question given this paragraph: In vascular plants, the sporophyte generation is dominant. Q: In vascular plants, the sporophyte generation is what? Choices: - non-existant - submissive - resting - dominant A:
Answer: dominant

Answer the following question given this paragraph: Recall that eukaryotic organisms also include animals, protists, and fungi. Eukaryotes have cells with nuclei that contain DNA, and membrane-bound organelles, such as mitochondria. Photosynthesis is the process by which plants capture the energy of sunlight and use carbon dioxide from the air (and water) to make their own food, the carbohydrate glucose. Plants have chloroplasts, the organelle of photosynthesis, and are known as producers and autotrophs. Other organisms are heterotrophic consumers, meaning they must obtain their nutrients from another organism, as these organisms lack chloroplasts. Lastly, plants must be multicellular, composed of more than one cell. There are no single-celled plants. Recall that some protists, such as algae, are eukaryotic and photosynthetic but are not considered plants. Unlike plants, algae is mostly unicellular. Q: What is the process by which plants capture the energy of sunlight and use carbon dioxide from the air (and water) to make their own food called? Choices: - spermatogenesis - photochemistry - atherosclerosis - photosynthesis A:
**Answer**
photosynthesis
Q: Answer the following question given this paragraph: Q: Every species has a characteristic number of what? Choices: - ribosomes - receptors - DNA - chromosomes A:
