meaning of epidemic virus pandemic
Answers
A pandemic is defined as “an epidemic occurring worldwide, or over a very wide area, crossing international boundaries and usually affecting a large number of people”. The classical definition includes nothing about population immunity, virology or disease severity.
By this definition, pandemics can be said to occur annually in each of the temperate southern and northern hemispheres, given that seasonal epidemics cross international boundaries and affect a large number of people. However, seasonal epidemics are not considered pandemics.
Answer:
The meaning of this answer is...
AN EPIDEMIC is a disease that affects a large number of people within a community, population, or region. A PANDEMIC is an epidemic that's spread over multiple countries or continents.

Which of the following is NOT one of the key characteristics of a well-designed test?
A) standardization
B) reliability
C) validity
D) brevity
Answers
Answer:
D) brevity
Explanation:
A test can be defined as an examination or quiz given to a student (pupil) during an academic calendar in order to measure or determine his or her intelligence. It is usually graded based on a set of defined grades or scores.
The key characteristics of a well-designed test includes the following;
I. Standardization: it is important that test is set based on certain criteria and acceptable rules within the education community and curriculum.
II. Reliability: the questions contained in a test should be credible and backed by correct answers.
III. Validity: the test questions should be genuine and authentic across board.
However, brevity simply means succinctness or conciseness i.e the test should be brief and very short in duration.

You decide to create a composting bin for your house. While checking on it one day, you notice that the compost bin has started to smell like rotting eggs. You know that a successful compost bin should not smell like this. You take a sample of the pile and check for the presence of microorganisms under the microscope. You see that there are indeed microorganisms. Given this information, what should you do to resolve the smell of your compost?(1 point)
Creating a tent for the pile to shield it from the sun and heat will help resolve the smell.
Turning the pile to aerate the compost and expose it to oxygen will help resolve the smell.
Adding more “brown” materials to the pile to increase the amount of carbon will help resolve the smell.
Adding more “green” materials to the pile to increase the amount of nitrogen will help resolve the smell.

- both a and c
- is an abnormality resulting from a diet high in cholesterol
Answers
Answer:
b) It interferes with the movements of the fatty acid tails of the phospholipids.
Explanation:
Cholesterol has many important functions, including its role in membrane permeability, especially the cell membrane, and its role in metabolism. Cholesterol reduces the permeability of lipid membranes. ... Cholesterol helps to restrict the passage of molecules by increasing the packing of phospholipids. Steroid molecule that makes membranes more fluid at low temps and more ordered at high temps.
- Flat, rigid, carbon rings interfere with the movement of phospholipids.
- Smaller and less amphipathic lipid that is only found in animals.
- Sandwiched between fatty acid tails of phospholipids.

a. how igneous rocks were formed over time
b. a trace or print, or the remains of a plant or animal of a past age preserved in Earth or rock
c. layers of sediment building up over time and pressing down, forming rock
4. Sedimentary rock is the second category. These rocks cover most of Earth’s land. Sedimentary rocks are made of pieces of other rocks and shells. Erosion causes rocks to slowly wear away. Erosion can be caused by rain, wind, freezing, and plant roots. Sometimes small pieces of rock are made because of erosion. The small pieces of rock are called sediment. Rivers take sediment to oceans and lakes. The river drops the sediments as it slows down. The sediments settle to the bottom in layers. More and more layers of sediment are dropped over millions of years. The weight from the top layers turns the bottom layers of sediments into rock. This makes some sedimentary rocks look layered. Fossils are often found in sedimentary rocks.

b. a trace or print, or the remains of a plant or animal of a past age preserved in Earth or rock

Why is cigaratte smoking injurious to health ?
Name the enzyme which is present in infants but may be absent in adults.
Answers
Explanation:
cigaratte smoking is injurious to health because it affects our lungs,heart and different internal organs of our body which is cause of cancer and other non curable diseases.
Answer:
During smoking the cigarettes fumes make the walls alveoli very thin which causes rupturing of alveoli. This reduces the surface area for gaseous exchange in lungs .
To make up for the reduces gaseous exchange the heart has to pump more blood.

Explanation:
I think it's correct
The Dinosaur that most likely evolved from Coelophysis is known as Camptosaurus. Thus, the correct option for this question is A.
What is Evolution?Evolution may be characterized as the complete methodology of gradual change that takes place over many generations, during which species of animals, plants, or insects slowly change some of their physical characteristics.
Coelophysis lived during the late Triassic period some 216.5 to 203.6 million years ago. Researchers believe that this small theropod lived on river floodplains where it walked alongside crocodilian-like Camptosaurus. They were small theropod dinosaurs that lived in what is now North America and Southern Africa during the late Triassic.
Therefore, the Dinosaur that most likely evolved from Coelophysis is known as Camptosaurus. Thus, the correct option for this question is A.

The best way to practice sustainable use of rangelands is to
Answers
Answer: 1. Rotating the rangelands that are being used.
2. Reducing overgrazing of rangelands.
Explanation:
Rangelands are the sites which are occupied and dominated by vegetation cover mostly the shrubs and herbs. It can be occupied by grasses. Overgrazing by the cattle cause a huge damage to the field of rangeland so it can cause soil erosion and can convert the rangeland on barren land. The regrowth rate is slower than that of the consumption rate of the cattle. So, reduction in overgrazing is advisable to maintain the sustainability of the land. Rotation of the rangelands being used if the cattle are taken to the different grassland for grazing on alternate days then the rangelands can be maintained sustainably.

d. The further apart animals are on a tree, the more closely they are related.
Answers
Answer:
The closer animals are located on a tree, the more characteristics they share.
Explanation:
The pattern of branching in a phylogenetic tree reflects how species or other groups evolved from a series of common ancestors. In trees, two species are more related if they have a more recent common ancestor and less related if they have a less recent common ancestor.
