Q: In which way do vertebrates reproduce? Read this paragraph and choose the correct option from the provided answers: Vertebrates reproduce sexually, and almost all of them have separate male and female sexes. Generally, aquatic species have external fertilization, whereas terrestrial species have internal fertilization. Can you think of a reason why aquatic and terrestrial vertebrates differ in this way?. Choices: - bisexually - unisexually - asexually - sexually A:
sexually

Q: What two-word term refers to the number of different species in the community? Read this paragraph and choose the correct option from the provided answers: Choices: - bacteria richness - group-richness - face-richness - species richness A:
species richness

Q: Q: What kind of fertilization do birds have? Read this paragraph and choose the correct option from the provided answers: Birds reproduce sexually and have internal fertilization. Mating is generally preceded by courtship. Their amniotic eggs have hard shells and are laid in a nest. The eggs are usually incubated until they hatch. Most species have a relatively long period of parental care. Choices: - deep fertilization - asexual - sensitive fertilization - internal fertilization A:
A: internal fertilization

Question: Q: Which carbohydrate is produced by photosynthesis? Read this paragraph and choose the correct option from the provided answers: Glucose is the carbohydrate produced by photosynthesis. Energy-rich glucose is delivered through your blood to each of your cells. Choices: - protein - insulin - sugar - glucose A:
Answer: glucose

Q: Humans are unique in their ability to alter their environment with the conscious purpose of increasing what, which acts as a limiting factor on populations in general? Read this paragraph and choose the correct option from the provided answers: Overcoming Density-Dependent Regulation Humans are unique in their ability to alter their environment with the conscious purpose of increasing its carrying capacity. This ability is a major factor responsible for human population growth and a way of overcoming density-dependent growth regulation. Much of this ability is related to human intelligence, society, and communication. Humans can construct shelter to protect them from the elements and have developed agriculture and domesticated animals to increase their food supplies. In addition, humans use language to communicate this technology to new generations, allowing them to improve upon previous accomplishments. Other factors in human population growth are migration and public health. Humans originated in Africa, but have since migrated to nearly all inhabitable land on the Earth. Public health, sanitation, and the use of antibiotics and vaccines have decreased the ability of infectious disease to limit human population growth. In the past, diseases such as the bubonic plaque of the fourteenth century killed between 30 and 60 percent of Europe's population and reduced the overall world population by as many as 100 million people. Today, the threat of infectious disease, while not gone, is certainly less severe. According to the World Health Organization, global death from infectious disease declined from 16.4 million in 1993 to 14.7 million in 1992. To compare to some of the epidemics of the past, the percentage of the world's population killed between 1993 and 2002 decreased from 0.30 percent of the world's population to 0.24 percent. Thus, it appears that the influence of infectious disease on human population growth is becoming less significant. Choices: - density dependent limitation - containing capacity - niche - carrying capacity A:
**Answer**
carrying capacity

Q: Q: What three rs represent the steps that you personally can take to conserve our natural resources and minimize waste? Read this paragraph and choose the correct option from the provided answers: Reduce, reuse, and recycle. There are steps that you personally can take to conserve our natural resources and reduce waste. The waste that an individual creates is small in proportion to all the waste produced by society. Yet all small contributions, when added up, make a difference. Choices: - rinse, reuse, recycle - remove, reduce, reuse - reduce, reuse, re-educate - reduce, reuse, recycle A:
A: reduce, reuse, recycle
