Answer the following question given this paragraph: Introduction Animal reproduction is necessary for the survival of a species. In the animal kingdom, there are innumerable ways that species reproduce. Asexual reproduction produces genetically identical organisms (clones), whereas in sexual reproduction, the genetic material of two individuals combines to produce offspring that are genetically different from their parents. During sexual reproduction the male gamete (sperm) may be placed inside the female's body for internal fertilization, or the sperm and eggs may be released into the environment for external fertilization. Seahorses, like the one shown in Figure. Q: What kind of reproduction produces genetically identical organisms or clones? Choices: - Prophase I - Meiosis - Sexual - asexual A:
asexual

Answer the following question given this paragraph: While the egg is developing, other changes are taking place in the uterus. It develops a thick lining that is full of tiny blood vessels. The lining prepares the uterus to receive a fertilized egg if fertilization actually takes place. Q: While the egg is developing, other changes are taking place in the uterus. it develops a thick lining that is full of what? Choices: - large arteries - white blood cells - amniotic fluid - tiny blood vessels A:
(Answer)
tiny blood vessels
Ques: Answer the following question given this paragraph: The Water Cycle Water is essential for all living processes. The human body is more than one-half water and human cells are more than 70 percent water. Thus, most land animals need a supply of fresh water to survive. Of the stores of water on Earth, 97.5 percent is salt water (Figure 20.9). Of the remaining water, 99 percent is locked as underground water or ice. Thus, less than one percent of fresh water is present in lakes and rivers. Many living things are dependent on this small amount of surface fresh water supply, a lack of which can have important effects on ecosystem dynamics. Humans, of course, have developed technologies to increase water availability, such as digging wells to harvest groundwater, storing rainwater, and using desalination to obtain drinkable water from the ocean. Although this pursuit of drinkable water has been ongoing throughout human history, the supply of fresh water continues to be a major issue in modern times. Q: Around 97% of all water on earth is what type of water? Choices: - excess water - fresh water - rivers water - salt water A:
Ans: salt water

Answer the following question given this paragraph: A nonrenewable resource is a natural resource that is consumed or used up faster than it can be made by nature. Two main types of nonrenewable resources are fossil fuels and nuclear power. Fossil fuels , such as petroleum, coal, and natural gas, formed from plant and animal remains over periods from 50 to 350 million years ago. They took millions of years to form. Humans have been consuming fossil fuels for less than 200 years, yet remaining reserves of oil can supply our needs only until around the year 2055. Natural gas can only supply us until around 2085. Coal will last longer, until around the year 2250. That is why it is so important to develop alternate forms of energy, especially for our cars. Today, electric cars are becoming more and more common. What would happen if we ran out of gasoline? Alternative use of energy, especially in transportation, must become a standard feature of all cars and trucks and planes by the middle of the century. Q: A natural resource that is consumed or used up faster than it can be made by nature is termed what? Choices: - renewable - energy-inefficient - fossil fuel - non-renewable A:
(A).
non-renewable
Ques:Answer the following question given this paragraph: Recall that the only required ingredients needed for photosynthesis are sunlight, carbon dioxide (CO 2 ), and water (H 2 O). From these simple inorganic ingredients, photosynthetic organisms produce the carbohydrate glucose (C 6 H 12 O 6 ), and other complex organic compounds. Essentially, these producers are changing the energy from the sunlight into a usable form of energy. They are also making the oxygen that we breathe. Oxygen is a waste product of photosynthesis. Q: For photosynthesis to begin, the inputs required are sunlight, water, and what? Choices: - phosphorus dioxide - methane - sulfur dioxide - carbon dioxide A:

Ans:carbon dioxide
Question: Answer the following question given this paragraph: Q: What organism is the most disruptive towards the diversity of other species? Choices: - bacteria - reptiles - insects - humans A:
Answer:
humans
