Science isn't just gathering factual information and data, it's a body of knowledge. It's a way of thinking about problems, and how to solve them. Science shapes everything in our world since everything revolves around natural rules.
It's thanks to computer <em>science </em>that you're able to be on this site right now. It's thanks to <em>science </em>as a whole that we have any of the technology we have today, and the cures for the many once <em>deadly </em>diseases. So, if you want to know how science shapes our world... Just look around you. =)
Answer:
Because the sika has more than one main food source incase all the shrubs die it can move on to the grass without a problem.
Explanation:
So the answer is A.
Answer: c) the anticipated geographical spread of a disease based on past observances.
Explanation: Prevalence simply means the widespread of a thing or condition. In epidemiology, prevalence can be defined as the total number of people in a population that is affected by a medical condition or total number of cases of a disease in a population in a given period of time.
Expected prevalence of a disease is therefore the anticipated widespread of a disease or the anticipated total number of cases of a disease in a population based on past observed incidences.
Answer: it might Be C or B
Explanation:
Answer:
The correct model is D.
Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.
Explanation:
A water molecule is composed of one atom of oxygen and two atoms of hydrogen.
A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.
The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.
