Answer the following question given this paragraph: Several lethal viruses that cause viral hemorrhagic fever have been discovered, two of which are shown in the Figure below . Ebola outbreaks have been limited mainly to remote areas of the world. However, they have gained extensive media attention because of the high mortality rate23 percent to 90 percentdepending on the strain. The primary hosts of the viruses are thought to be apes in west central Africa, but the virus has also been isolated from bats in the same region. Q: What are the 2 primary hosts of ebola in central africa? Choices: - hyenas and apes - apes and hippos - lions and elephants - apes and bats A:
apes and bats

Answer the following question given this paragraph: Scientists first make observations that raise questions. An observation is the act of noting or detecting phenomenon through the senses. For example, noting that a room is dark is an observation made through sight. Q: What is the act of noting or detecting phenomenon through the senses Choices: - sensory overload - invention - overstimulation - an observation A:
(Answer)
an observation
Ques: Answer the following question given this paragraph: It is believed that large mutations form new genes. Mutations that duplicate large sections of DNA are a major source of genetic material for new genes. It is thought that tens to hundreds of genes are duplicated in animal genomes every million years. Most genes belong to larger families of genes of shared ancestry. These gene families have domains within the protein with a particular and independent function. These domains have corresponding conserved regions within their genes. It is through duplication mutations that such gene families formed. Genetic recombination after duplication of different domains forms new combinations of domains with new functions. For example, the human eye uses four genes to make structures that sense light: three for color vision and one for night vision; all four arose from a single ancestral gene. Q: What is essential for forming new genes? Choices: - enough mutations - enough chromosomes - chromosome deversity - large mutations A:
Ans: large mutations
(Q).
Answer the following question given this paragraph: Kinetic energy is the energy of moving matter. Things with kinetic energy can do work. Kinetic energy depends on an object's mass and velocity. Q: What is the energy of moving matter? Choices: - potential energy - binary energy - residual energy - kinetic energy A:
(A).
kinetic energy
Ques:Answer the following question given this paragraph: Clouds form when water vapor condenses around particles in the air. The particles are specks of matter, such as dust or smoke. Billions of these tiny water droplets come together to make up a cloud. If the air is very cold, ice crystals form instead of liquid water. Q: What forms when water vapor condenses around particles in the air? Choices: - wind - storms - humididty - clouds A:

Ans:clouds
Ques:Answer the following question given this paragraph: Population density is an average measure. Often, individuals in a population are not spread out evenly. Instead, they may live in clumps or some other pattern. How individuals in a population are distributed, or spread throughout their area, is called population distribution. You can see different patterns of population distribution in Figure below . Different patterns characterize different species and types of environments, as you can read in the figure. Q: Which measure shows how individuals in a population are distributed, or spread throughout their area? Choices: - geographical distribution - population phase - proportional distribution - population distribution A:

Ans:
population distribution
