Q: Please answer correctly the following question related to the paragraph below. Given an animal such as a cow is born very mobile and capable of taking care of itself, would it be classified as precocial or altricial? Mary's dog just gave birth to a litter of puppies! As of right now the puppies eyes are closed so they can't see. They require the mother to take very close care of them while they grow to keep them safe. Hint: 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.
A: precocial
Question: Please answer correctly the following question related to the paragraph below. Which student learned less about exposure of the skin to UV radiation? Bob and Bill studied at the same university. While Bob got into studying nutrition, Bill ended up studying about cancer and how to prevent it. Hint: Making these healthy lifestyle choices can also help prevent some types of cancer. In addition, you can lower the risk of cancer by avoiding carcinogens , which are substances that cause cancer. For example, you can reduce your risk of lung cancer by not smoking. You can reduce your risk of skin cancer by using sunscreen. How to choose a sunscreen that offers the most protection is explained below ( Figure below ). Some people think that tanning beds are a safe way to get a tan. This is a myth. Tanning beds expose the skin to UV radiation. Any exposure to UV radiation increases the risk of skin cancer. It doesn't matter whether the radiation comes from tanning lamps or the sun.
Answer: Bob
[Q]: Please answer correctly the following question related to the paragraph below. Which farmer dealt with fewer aphids resistant to organophosphates? Bill and Paul were farmers. Bill used insecticides to get read of aphids, while his buddy farmer Paul didn't. Hint: Insecticide control of aphids is difficult, as they breed rapidly, so even small areas missed may enable the population to recover promptly. Aphids may occupy the undersides of leaves where spray misses them, while systemic insecticides do not move satisfactorily into flower petals. Finally, some aphid species are resistant to common insecticide classes including carbamates, organophosphates, and pyrethroids.For small backyard infestations, spraying plants thoroughly with a strong water jet every few days may be sufficient protection. An insecticidal soap solution can be an effective household remedy to control aphids, but it only kills aphids on contact and has no residual effect. Soap spray may damage plants, especially at higher concentrations or at temperatures above 32 C (90 F); some plant species are sensitive to soap sprays.

input: Please answer the following: Please answer correctly the following question related to the paragraph below. Would species A have larger or smaller habitat than species B? John is a biologist. Last summer, he was studying the evolution of two different salamander species, species A and species B. Species A salamander was Gold-striped salamander while species B salamander was fire salamander. He found it interesting that they took different approaches to adapt to different habitats. Hint: Consider the antlers of the Irish elk, (often supposed to be far too large; in deer antler size has an allometric relationship to body size). Obviously, antlers serve positively for defence against predators, and to score victories in the annual rut. But they are costly in terms of resource. Their size during the last glacial period presumably depended on the relative gain and loss of reproductive capacity in the population of elks during that time. As another example, camouflage to avoid detection is destroyed when vivid coloration is displayed at mating time. Here the risk to life is counterbalanced by the necessity for reproduction.Stream-dwelling salamanders, such as Caucasian salamander or Gold-striped salamander have very slender, long bodies, perfectly adapted to life at the banks of fast small rivers and mountain brooks. Elongated body protects their larvae from being washed out by current. However, elongated body increases risk of desiccation and decreases dispersal ability of the salamanders; it also negatively affects their fecundity. As a result, fire salamander, less perfectly adapted to the mountain brook habitats, is in general more successful, have a higher fecundity and broader geographic range.

Please answer this: Please answer correctly the following question related to the paragraph below. Whose farm, Robert's or Dale's, will have cows that produce lower amounts of milk? Robert and his brother Dale are both dairy farmers that primarily produce milk products. Both Robert and Dale have farms that approximately the same size. Dale prefers to produce milk conventionally, as he likes the way that conventional milk tastes. Robert, on the other hand, decided to switch to organic milk production after reading an article online about it. Hint: Compared to conventional milk production, organic milk production tends to have lower eutrophication potential per ton of milk or per hectare of farmland, because it potentially reduces leaching of nitrates (NO3) and phosphates (PO4) due to lower fertilizer application rates. Because organic milk production reduces pesticides utilization, it increases land use per ton of milk due to decreased crop yields per hectare. Mainly due to the lower level of concentrates given to cows in organic herds, organic dairy farms generally produce less milk per cow than conventional dairy farms. Because of the increased use of roughage and the, on-average, lower milk production level per cow, some research has connected organic milk production with increases in the emission of methane.Animal welfare issues vary among dairy farms and are not necessarily related to the way of producing milk (organically or conventionally).

Answer: Robert's
Question: Please answer correctly the following question related to the paragraph below. Which student read more about protozoa preying upon bacteria? Students learned about protozoa in school this week. Dan and Jim were interested and read more on the subject. Dan read more about predatory protozoa, while Jim read more about herbivore protozoa. Hint: Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations in check. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. For their part, protozoa are important food sources for many larger organisms, including insects and worms.
Answer:
Dan
