1. What is the weight of an object that has a base of 3 square meters and has a pressure of 21 newtons per square meters?
Answer:
63N
Explanation:
To calculate the weight (force) that an object exerts, the formula is used:
Pressure = Force / Area
Where; P = pressure
F = applied force
A = the surface area the
force is applied to
According to the question; P= 21N/m^2,
F= ?, a = 3m^2
Force = pressure × area
Force = 21 × 3
Force = 63N
Hence, the weight of the object is 63N
In the morning, the water levels in a local marsh rise and cover the clam beds. In the evening the water level decreases, making it easier for local fisherman to collect clams. What type of disruptive event does this describe?
Episodic
Extinctive
Periodic
Random
Answer:
Periodic
Explanation:
got the question right
Disruptive events are disasters that disturb the pre-determined arrangement. The change in the water level in the local marsh is an example of periodic disruptions. Thus, option C is correct.
What are periodic disruptions?Periodic disruptions are the disturbances in that occur in a regular time interval at a fixed rate and fix time. The episodic are occasional and irregular events, while the random is not determined and fixed at all.
The water level shows the period movement as it decreases in the evening and rises in the morning. It shows that the water level rises and decreases in a regular pattern and time.
Therefore, the rise and decrease in water level is a periodic disruptive event.

HELP FAST write a 3 sentence explanation of this picture using the terms bioaccumulation and biomagnification
Answer:
Explanation:Bioaccumulation occurs when toxins build up - or accumulate - in a food chain. The animals at the top of the food chain are affected most severely. This is what happens: Small amounts of toxic substances - often pesticides or pollution from human activity - are absorbed by plants.while biomagnification is the process by which toxins are passed from one trophic level to the next (and thereby increase in concentration) within a food web. ... dissolve into the fatty tissues of living organisms.
The data in the table has been converted into a bar graph, as shown below. Amount of Carbohydrates in Fruit A 2-column table with 7 rows. Column 1 is labeled 237 Milliliters of Fruit with entries Apples, Bananas, Cherries, Grapefruits, Oranges, Peaches, Watermelons. Column 2 is labeled Carbohydrates (Grams) with entries 17, 34, 19, 24, 21, 16, 12. A graph titled Grams of Carbohydrates in 237 Milliliters of Fruit shows fruit on the x acid and Carbohydrates in grams on the y axis. There are 17 Apples, 34 Bananas, 19 Cherries, 24 Grapefruits, 21 Oranges, 16 Peaches, 12 Watermelons. Which reason provides the best explanation of why a bar graph was selected to show the data in the table? Bar graphs are used to compare separate items. Bar graphs are used when data are continuous. Bar graphs are often used to show mass. Bar graphs are the easiest to construct and to read.
Answer:
Bar graphs are used to compare separate items.
Explanation:
A bar graph is used because it helps to compare items. So the correct option is A.
What are bar graphs?
Bar graphs are a kind of pictorial representation of data which is generally in grouped form. It can present the data in the form of both vertical and horizontal rectangular bars.
In this graph, the length of the bars is used as proportionate to the value of data. These graphs are also called bar charts. Bar graphs are one of the various methods of data handling in the field of statistics.
Statistics is defined as the collection, presentation, organisation, analysis, and interpretation of data observations. In statistics, there are various other methods of data representation. These are tables, bar graphs, pie charts, histograms, frequency polygons, etc.
A bar graph is one of the several methods of data representation and is used for comparing the values of items in the data.
Therefore the correct option is A.

Describe what defines a factor that is tested in a controlled experiment
All living cells must maintain homeostasis or internal stable conditions in order to survive. Which of the following processes would best help a cell to maintain these conditions
(SC.6.1.142)
АО
using energy
BO
creating DNA
using carbon dioxide
creating water molecules
Answer:
None of the options provided is correct but some are close
Explanation:
One of the ways in which a cell maintain homeostasis is by regulating what goes in and out of the cell through the cell membrane (which is a semi-permeable barrier). The amount of water is highly regulated by the cell in this case so as to regulate osmosis (movement of water molecules from a region of higher concentration to a region of lower concentration). Other substances regulated are oxygen and carbon dioxide.
NOTE: The cell does not create water molecules neither does it use carbon dioxide to maintain homeostasis, it rather regulates these two compounds.

n the 1600's, Robert Hooke, and English scientist, used a crude microscope to examine bits of cork. Cork is derived from the bark layer of certain trees. Upon seeing the cork under the microscope, Hooke named the spaces within the cork 'cells', because they looked like empty rooms of a monastery. Although he coined the term cell, an ironic feature of cork is that it is dead plant material. Knowing this, what feature of cells would Robert Hooke NOT have been able to observe under the microscope while looking at cork?
Answer:
the answer is C: he would not be able observe cork cells dividing to form new cells

, What behavioral genetic research finding seems to support the conclusion that the effect of growing up in the same home environment is rather minimal? a. The personality traits of adoptive siblings raised in the same family are correlated around .05. b. The personality traits of monozygotic (MZ) twins are correlated at .50 on average. c. The personality traits of dizygotic (DZ) twins are correlated at .30 on average. d. The personality traits of adoptive siblings raised in the same family are correlated above .25.
Answer:
a. The personality traits of adoptive siblings raised in the same family are correlated around .05.
Explanation:
Both genes (inheritance) and environment play roles in literally everyone human traits including human personality. Nonetheless, recent research involving adoptive siblings and monozygotic twins, which are genetically identical, strongly suggest that there is a predominant genetic influence on this human trait. In consequence, environmental factors play minor roles in human behavior. In the case above indicated (i.e., adoptive siblings in the same home), the low correlation value shows a minor effect of the environment on the personality.
What is the acceleration due to gravity on another planet if the potential energy of an object on
that planet is 600 J, the mass of that object is 2 kg, and the height of that object is 3 meters?
Answer:
g = 66.7 ms^-2 (3 s.f.)
Explanation:
Potential Energy -> PE
m -> mass
g -> acceleration due to gravity
h -> height
using the formula, PE = mgh
600 = 3 × g × 3
9g = 600
g = 600/9
g = 66.666
g = 66.7 ms^-2 (3 significant figures)

Answer:
positive, negative, or no effect
Explanation:
It was right on the test
Positive, Negative or no effect can a chromosomal change can have on an organism. So, the correct option is (A).
What is Chromosomal change?When there is an increase or loss of chromosome number from the normal number of chromosomes which is 46, it is called aneuploidy. A common form of aneuploidy is trisomy which is the presence of an extra chromosome in cells.
"Tri-" is Greek for "three" which define as the people with trisomy have three copies of a particular chromosome in their cells instead of the normal two copies.
Chromosomal abnormalities can occur when an accident occurs when the egg or sperm are being formed or during the early developmental stages of the embryo. Maternal age and certain environmental factors may play a role in the occurrence of genetic errors. There are Positive, negative, or no effect in the chromosomal change.
Thus, Positive, Negative or no effect can a chromosomal change can have on an organism. So, the correct option is (A).

It would change the way they gain energy by the animals not having enough things in the body to get it functioning right.
Explanation:
think of it as gas our cars need gas to run, so do animals and us but our gas is food
If animal cells had chloroplasts, it means animals would be able to gain energy directly from sunlight by being able to manufacture carbohydrates as a food source.
The presence of chloroplast would allow an animal cell to photosynthesize and manufacture foods in the form of carbohydrates.
