How does a molecular compound compare to the elements that make up the compound?
Answer:
The only difference between a molecular compound and an element is that in an element all the molecules are the same, but in a molecular compound there are different types of elements that make up the compound.
So an element is something you find on the periodic table, a molecular compound is created using different types of elements.
List three particles found in blood plasma and give their main purpose.
Answer:
Blood plasma is a 'yellowish liquid' component of blood that holds the blood cells in whole blood in suspension. It is the liquid part of the blood that carries cells and proteins throughout the body. It makes up about 55% of the body's total blood volume. It is the intravascular fluid part of extracellular fluid. It is mostly water, and contains important dissolved proteins, glucose, clotting factors, electrolytes, hormones, carbon dioxide, and oxygen. It plays a vital role in an intravascular osmotic effect that keeps electrolyte concentration balanced and protects the body from infection and other blood disorders.

A scientific theory may be modified as new lines of evidence become apparent. D. Scientific theories are concise, systematic, predictive, and broadly applicable. E. Scientific theories often integrate and generalize many hypotheses. Neil deGrasse Tyson once commented: "Some claim evolution is just a theory, as if it was merely an opinion." He went on to explain why a scientific theory, like evolution, is NOT just an opinion. Select which points he included in his argument? A) A, B, E B) A, B, D, E C) A, B, C, E D) A, B, C, D, E
Answer:
D) A, B, C, D, E
Explanation:
These are all important factors to consider when judging scientific theories. A scientific theory is not merely an inclination or vague idea a scientist has. Instead, a scientific theory is an explanation that is given to a broad range of phenomena. Scientific theories tend to be concise, coherent, systematic and predictive. However, they also admit modification as new evidence becomes apparent.

Do you think it would be possible to construct a pyramid where the number of carnivores was more than the number of herbivores? Why or why not?
Do you think it would be possible to construct a pyramid where the biomass of carnivores was more than the biomass of herbivores? How does this compare to a numbers pyramid.
Please help!
Answer:
Explanation:
Pyramid is the use of graph to represents the flow of energy in each trophic level. There are five trophic level and each has its own energy level pyramid help to show the energy at each level.
Each energy level must have at least One tenth of the energy level of the organisms before itself, this indicates that the energy in the lower tropic level is higher than the trophic level above.
Hence, carnivores cannot be more than herbivores in a biomass they need enough of herbivores to survive in the biomass as the energy level moves from the herbivores to the carnivores.

Devegetation affected a number of nutrient reservoirs and processes in the experimental watershed. Note that the rate of decomposition was not affected by devegetation because the decomposers were not affected by the treatments and because the plant remains contributed plenty of organic nutrients to the soil to sustain decomposition for the duration of the experiment. Drag the labels to indicate the change in the size of the reservoir or the change in the rate of the process as a result of devegetation. Labels may be used once, more than once, or not at all.
Answer:
Devegetation affect the nutrient reservoir and watershed due to not using of nutrient and increases soil erosion.
Explanation:
Devegetation refers to no vegetation on a piece of land. If there is no vegetation present on land, the nutrient reservoir remain full because no plant is available for the absorption of nutrients from the reservoir. Devegetation also affect water quality of watershed. Erosion is the main problem of those areas where there is no vegetation and the upper layer of soil is washed by the rainfall.

Imagine an object launched from Earth as shown in the image. Identify where the object has overcome the gravitational pull of Earth.
Answer:
the object defeats the force of gravity on the arrows on the left where they do not follow the circumference of the earth.
since the force of gravity makes the objects keep rotating near or even on the Earth's surface.
If any object overcomes this force, it will not rotate on the surface of the earth and will not be attracted to the center
Explanation:
this is because the center of the earth works as if it were a magnetic pole that attracts everything close to the earth to its center, if something deviates as in the arrows on the left, it means that the force of attraction towards the center or force of gravity does not act on the objective as it must have a force applied or of its own greater than that written

Which region would likely have the greatest amount of biodiversity?
OA
B.
a mountainous region with two ecosystems, each of which supports a few different species
a grassland region with one ecosystem, which supports very large populations of a few different species
a coastal region with three ecosystems, each of which supports many different species
a cave region with one ecosystem, which supports small populations of many different species
D.
Answer:
A
Explanation:
A coastal region with three ecosystems, each of which supports many different species likely to have the greatest amount of biodiversity. The correct option is C.
The highest level of biodiversity would probably be found in a coastal area with three different habitats.
Because there are so many different habitats and ecological niches along the coast, there is frequently a high biodiversity there.
Sand beaches, rocky shorelines, coral reefs, mangrove forests, and salt marshes are just a few examples of the diverse environmental conditions that can be found in a coastal region due to the interaction of marine, estuarine, and terrestrial ecosystems.
There is a larger total species variety because various species are supported by each ecosystem and are adapted to their own habitats and environmental variables.
Additionally, because they produce intricate and interconnected ecological networks, interactions between different habitats further improve biodiversity.
Thus, the correct option is C.

What is the best method to increase the accuracy of the parallax measurement of star distances?
keep a record of the observations and do not repeat them
take observations simultaneously with different instruments
keep a gap of about six months between two observations
take observations from two points which are very close to each other
Answer:
C.
Explanation:
Parallax method is used to measure the distance of nearby objects in space or measurement of star distances. Parallax method uses the measurement of movement of star's against starts at far points as Earth revolves around the sun.
To improve the accurate measurement of star distances through parallax method, a gap of about six months between two observations.
In the parallax measurement, two angles are measured and it includes Earth on one side of its orbit, Earth six months later on the other side of its orbit and side of a triangle formed by the star. This six month gap ensures that measurement of stars is taken from two farthest points which gives a large arc length.
As parallax is based on geometry so, it ensure that the large arc length will reduce the error in the measurement of the angle and the distance will be accurate.
Hence, the correct answer is C.

La presencia de un núcleo organizado en el interior de la célula es característica de: a)celula procarionte b) celula eucarionte c) las bacterias d) los virus
Answer:
Translation- The presence of an organized nucleus inside the cell is characteristic of: a) prokaryotic cell b) eukaryotic cell c) bacteria d) viruses
Explanation:
Eukaryotic.These organim including man, are characterised with a double membrane nucleus, with all its inclusions. Other organisms lack a well organized membrane bounded nucleus. Rather they have orgellells that perform nearly similar functions close to the nucleus lying freely in the cytoplasm.
Nucleus is the control and coordinating centre of the cell.Genetic materials needed for instructions on how to produce other cells organelles are present in the nucleus.
Bacteria, Prokarotes contain Nucleoid, which is just an irregularly shape region, lacking nuclear membrane.
Viruses lack Nucleus.

C. smaller than 1.5 inches, warts, triangle between the eyes, stripe on back from head to tail
D. larger than 1.5 inches, smaller than 6 inches, smooth skin, triangle between the eyes
Answer:
The answer is B
Explanation:
I had this on study island.
Answer: Option D: larger than 1.5 inches, smaller than 6 inches, warts, no triangular mark on head, X-shaped mark on back
Explanation: Pseudacris crucifer is the last species of frog in the key. Therefore, one must work backwards through the entire key to determine Pseudacris crucifer's characteristics.The only way to get to step #5, where the frog was identified as Pseudacris crucifer, was to determine in step #4 that the frog had no triangular mark on its head.To get to step #4, the frog must not have had smooth skin. In order to get to step #3, our frog must have been smaller than 6 inches.Although we could have arrived at step 3 whether the frog was larger or smaller than 1.5 inches, the only answer choice provided that correctly listed the other characteristics of Pseudacris crucifer is : larger than 1.5 inches, smaller than 6 inches, warts, no triangular mark on head, X-shaped mark on back.
