four and two eighths minus two and five eighths equals
a number line from zero to three with a tick on every eighth
subject: science
Answer:
55/8 as a mixed fraction
Explanation:
4 2/8 - 2 5/8 = ?
Four and two-eighths can be represented as a mixed number by multiplying (4x8+2)/8 = 34/8
Two and five-eighths can be represented as a mixed number by multiplying (2x8+5)/8 = 21/8
Then, these two values can be easily added. 34+21 = 55/8
You can plot this on a number line by also representing these mixed fractions as a decimal, and then adding them - you can draw lines to represent the addition process.
Since the number line already represents a tick on every eighth (which is the fraction you would primarily be using), this will make it earlier.

Millions of dead or dying ash trees have to be removed by homeowners because of this insect, and many people still have to decide how to handle infestations.According to USDA studies, an ash tree that has lost more than half of its leaves due to EAB should probably be cut down. The majority of a tree's canopy, though, might make it a strong candidate for treatment.Trees are cut down so that their wood can be burned or utilized to create items like paper, furniture, and structures. Large tracts of trees are cut down to provide room for crops to be grown or for areas for farm animals to graze.Learn more about ash tree here:

A student is conducting their science experiment on the effect of caffeine on dogs. He has 3 groups of test subjects.
The 1st group of dogs receives plain water. The 2nd group of dogs receives 10 mg of caffeine each, and the 3rd
group receives 50 mg of caffeine each. He will measure their activity levels by recording how long each dog runs
without stopping, after giving them the pills. What could be evaluated in this experiment to ensure reliability?
A. If the dogs are different breeds, their activity levels could be different because of their breed and not the caffeine.
• B. The test subjects are dogs and not people, so their data is unreliable.
C. The different amounts of caffeine given could lead to different activity levels which would throw off the result of the experiment.
C D. The group that receives water will be an outlier and throw off the best fit line.
If the dogs are different breeds, their activity levels could be different because of their breed and not the caffeine. The correct option is A.
Reliability of experimentsIn order for the outcomes of scientific experiments to be reliable, constant variables should be kept constant.
In the illustrated experiments, the breed and age of the experimental dogs have to be the same. It is one of the variables that have to be kept constant throughout the experiment.
If the dogs are different breeds, their activity levels could be different because of their breed and not the caffeine. The same thing is applicable to different ages.

The area where trees grow is shifting.
Invasive species are destroying plants.
Less water is available.
Glaciers are melting.
Taigas are in danger as a result of climate change in various ways. The frozen layer below earths surface is partially melting as a result of the warming environment.
More of the taiga is being occupied by muskegs as a result of this water's lack of a drainage system.Deforestation brought on by logging and clear-cutting poses the biggest threat to the taiga. Timber is obtained using these techniques for the production of wood and paper goods. In order to build cities, forests are also destroyed, which might fragment habitats.In boreal coniferous forests, more forest fires are occurring more frequently as a result of global warming.

Why is the sympathetic nervous system referred to as the fight or flight system?
As you can see from the diagram below, the human nervous system is divided into two main components, the peripheral nervous system and the central nervous system.
The peripheral nervous system is further divided into two components. The somatic nervous system involves the voluntary movement of skeletal muscle. When you decide to raise your cup of coffee to your mouth, that is the somatic nervous system at work activating the appropriate muscles. The second component of the PNS is the autonomic nervous system, which controls processes that are out of our conscious control.
The autonomic nervous system is further subdivided into the parasympathetic nervous system and the sympathetic nervous system (which you are interested in). In very generalized terms, they have antagonistic effects on each other. The sympathetic nervous system generally activates the body, whereas the parasympathetic nervous system primarily acts to relax the body. This is a simplified view of things, but it is useful to think of it in this way.
The sympathetic division of the autonomic nervous system increases heart rate, inhibits digestion, relaxes bronchi in the the lungs to allow more airflow, causes the release of glucose from the liver, and relaxes the bladder. All of this activates the body, prepares it for a "fight".
In contrast, the parasympathetic division reduces heart rate, constricts bronchi in the lungs, and increases blood flow to the digestive tract. It has been called the "rest and digest" system.
As you can see from the diagram, the nerves of the parasympathetic nervous system come directly from the brainstem and spinal cord. However, with the sympathetic nervous system, there are "ganglia" (groups of cell bodies) outside the spinal cord itself.
Interestingly, the parasympathetic nervous system only uses Acetylcholine (ACh) to exert its effects on organs, but the sympathetic nervous system uses both ACh and norepinephrine (NE) to activate the body.
Its important to remember that the sympathetic and parasympathetic nervous systems are autonomic, meaning we generally have little control over them.

What is Meiosis?Meiosis is a special type of cell division which is also known as reductional division. It occurs in the germ cells in the sexually-reproducing organisms that involves the formation of the gametes, such as sperm or egg cells. Meiosis involves two rounds of division which are Meiosis I and Meiosis II, which ultimately results into formation of four daughter cells with only one copy of each chromosome.
Meiosis is an important type of cell division for three main reasons which are sexual reproduction of diploid organisms in which it produces gametes, it enables genetic diversity in sexually reproducing organisms, and it reduces the chromosome number in the daughter cells by half.

A. Suppression allows weaker, more vulnerable trees that would have been weeded out by fire to survive.
B. Suppression leads to less diversity of tree species, so beetles spread more quickly between trees.
C. Suppression leads to equal/even-age stands of mature trees, which the beetles prefer.

2. NATURAL forest fires can temporarily increase fertility of a region
3. burning process releases nutrients which then fertilize the soil.
3a. fire chemically converts nutrients bound in dead plant tissues and the soil surface to more available forms
3b. fire indirectly increases mineralization rates through its impacts on soil microorganisms (Schoch and Binkley 1986).

Can anybody tell me how cell shape affects function? For example if columnar and epithelial cells shapes affect their respective functions?
Answer:
Cell Shape: Large surface area = Function: Absorption/metabolism increases
Explanation:
The large the surface area of a cell allows for more receptors to interact to increase the amount of metabolism that occurs within the cell. The example you provided, columnar and epithelial cells, are found in various locations throughout the body but are most notable found in the intestinal lining of our intestines. The shape of the columnar which is made up of epithelial cells is waved shaped to allow for more surface area within a given location. Consequently, leading to further absorption.
