Answer:
yes, this is true.
Explanation:
an experiment that uses sound scientific principles includes the important step of scientists communicating ideas and experimental results. Provide two examples of how scientists communicate experimental results. WILL GIVE BRAINLIEST AND 20 POINTS!!
Scientists often communicate their research results in three general ways. but this only asks for 2 so I'm giving 2 haah anyway .One is to publish their results in peer reviewed journals that can be ready by other scientists. Two is to present their results at national and international conferences where other scientists can listen to there presentations or presentations in general.

EXPERIMENT: DETERMINING VOLUME
Here are your goals for this lesson:
Measure a common geometric shape in centimeters and record answers
Calculate volume for the geometric shape
Utilize the method of displacement to determine volume
Answer questions and summarize results
If you ever dropped something into a full pail of water, you might have noticed that some of the water flowed over the edge of the pail. Whatever was dropped into the pail took up some of the space that had been filled by the water. As a result, some of the water was displaced from (pushed out of) the pail. The amount of space that matter takes up is called the volume of that matter. Thus a giant boulder has more volume than a small rock. Any unit of matter, large or small, solid, liquid, or gas, takes up space and therefore has volume.
In this experiment, you will attempt to determine the volume of two objects, using two different methods, listed below:
1. For an object of uniform shape having linear sides or a common geometric shape, measure the object and determine the volume mathematically.
2. For an irregularly shaped object that cannot be measured easily or does not consist of uniform geometric shapes, determine the volume of water it displaces. The volume of water displaced equals the volume of the object as long as the object does not absorb or dissolve in water.
When measuring the volume of water in a graduated cylinder or similar container, be sure you read the lowest point of the curved surface of the water, the meniscus. Study Figure 1 to find the correct level.
1. Find the volume of an object with linear sides or a common geometric shape.
These supplies are needed: a metric ruler and an object with linear sides or a common geometric shape
A. Volume equals length times width times height (V = l × w × h). The amount of space that an object takes up is its volume.
B. Measure in centimeters (cm) the length, width, and height of the object and record your answers.
Note: Be sure you included the units (cm) with each measurement.
C. Multiply the length by the width by the height. This is the volume of the object.
Volume = l × w × h = _____ × _____ × _____ = _____ cm3
Since you went from linear measurement (cm) to cubic measurement (cm3 ), the units change and your answer will be in cubic centimeters (cm3 ).
2. Find the volume of an irregularly-shaped object.
These supplies are needed: string, water, small rock, graduated cylinder
A. Pour water into a graduated cylinder until it is about half full, stopping at one of the level marks on the cylinder.
B. Read and record the level of the water. This reading is the volume of the water. Be sure you are reading at the lowest point of the curved surface or meniscus. Study Figure 1 above to see how to read the correct level.
C. Tie the string on the rock and lower the rock completely into the water. Let it settle at the bottom.
D. Record the level of the water with the rock in it. This reading is the volume of the water and the rock.
E. Find the volume of the rock by subtracting the reading of the water from the reading of the water and the rock.
(water and rock) - (water) = _____ cm3. Your answer is the volume of the rock.
3. Compose a scientific summary of your method, observations, data, and conclusions. In addition, be sure to answer the questions below in your report.
Why does the first method for determining volume work only for a regular-shaped object?
Will the second method for determining volume work for any object or just an odd-shaped one? Why?
Is one method of measurement more accurate than the other? Why or why not?
Would the displacement method of measurement work for a cube of sugar? What about a cork? Why?
What did you find out from this investigation? Be thoughtful in your answer.
Anyone who answers improperly will be reported please only answer if you have the answer. Thank You :))
10 points and Brainliest for best answer! goood luck!
Explanation:
(Ques- A) Why does the first method for determining volume work only for a regular-shaped object?
(Ans- A) Because the method requires precise dimensions of objects for result, which is not possible for irregular shaped objects.
(Ques - B) Will the second method for determining volume work for any object or just an odd-shaped one? Why?
(Ans-B) It will work for both regular and irregular shaped objects since both displace equal volumes of water.
(Ques - C) Is one method of measurement more accurate than the other? Why or why not?
(Ans-C) Both are pretty accurate, with some experimental errors which may creep in accidentally.
(Ques- D) Would the displacement method of measurement work for a cube of sugar? What about a cork? Why?
(Ans - D) No, the method would not work because sugar being soluble, will dissolve in water.
No, the method would not work because sugar being soluble, will dissolve in water. Cork is less dense than water so floats on it, with only part of it submerged in water, resulting in displacement of less volume of water than actual volume of Cork.
(Ques-E) What did you find out from this investigation? Be thoughtful in your answer.
(Ans- E) I learnt about determining volume of different objects from this investigation. (Sorry, I know its not a very thoughtful answer)
What function do a brain cell and liver cell have in common?
The liver cells produce many enzymes that catalyze many chemical reactions, even in nerve cell many chemical reaction occur.
What is the function of liver cell ?The liver is the major organ like brain as it involves many metabolic process, liver cells make many enzymes that catalyze many different chemical reactions.
It involve in Carbohydrate metabolism, it maintain blood glucose level by converting excess glucose to glycogen by the process called glycogenesis, facilitate by insulin and cortisol.
During stress situations, glycogen is converted to glucose by the process of glycogenolysis which increase the blood glucose level, facilitate by Epinephrine and glucagon.
It involve in Amino acid metabolism by synthesizing 12, non-essential amino acids in the process called transamination.
Excess amino acids cannot be stored and it can be removed by the process of deamination means NH2 group is removed from an amino acid, and the remaining carbon converted to a simple carbohydrate or fat.
It involve in Lipid metabolism, it forms lipoproteins for the transport of fats in the blood to other tissues, synthesizes cholesterol and excretes it into bile for the elimination in feces.

Answer:
Radiation: 5, 2
Conduction: 6, 7
Convection: 3, 1, 4, 8
P.S. It's been a while since we have touched that topic in school but I did a little of research on my laptop and I think I got them figured out
Hope this helps :)
Answer:
Explanation:
So remember that radiation means electromagnetic waves going from one object to another. So an example would be holding a pot over a stove or a fire. It heats up the object. Conduction is heat touching something. So an example of that could be you touching a really hot oven or pot handle. And convection is when warmer air or liquid rises. So an example would be water boiling inside the pot. Hope this helps and if it does would you mind giving brainliest please. Luv you girly

Density can be calculated by dividing the mass of an object by its volume. Water has a density of 1g/ml. If an object’s density is greater than 1 g/ml it will sink and if its density is less than 1g/ml it will float?
Answer:
yes
Explanation:
The density of an object determines whether it will float or sink in another substance. An object will float if it is less dense than the liquid it is placed in. An object will also sink if it is more dense than the liquid it is placed in
Do all organisms have organs? Explain
Answer:
No, there are some organisms that only have one cell, although there are organ systems that are made up of many cells. Not all organisms have organ systems.
Explanation:
For example, the Trichoplax. It is an animal with no organs that is tiny and multicellular, and only feeds on microalgae. A Trichoplax are flat organisms about a millimetre in diameter with no internal structures and typically have two cellular layers. These organisms live in the oceans and seas all around the world but are not necessarily found in their natural habitat, more so in captivity such as a marine aquarium. Trichoplax are found to live in symbiosis with such things as bacteria and others in the oceans and seas.

Why would the white blood cells have an abundance of lysosomes?
A. White blood cells have many lysosomes because they need to produce a lot of glucose and oxygen.
B. White blood cells have many lysosomes because they need to destroy pathogens with digestive enzymes.
C. White blood cells have many lysosomes because they need lots of ATP to help carry oxygen.
D. White blood cells have many lysosomes because they need to produce lots of proteins to help build muscle.
Answer:
Explanation:
A. White blood cells have many lysosomes because they need to produce a lot of glucose and oxygen.
Lysosomes are found in all animal cells, but are most numerous in disease-fighting cells, such as white blood cells. This is because white blood cells must digest more material than most other types of cells in their quest to battle bacteria, viruses, and other foreign intruders.
White blood cells have an abundance of lysosomes because ( B ) : White blood cells have many lysosomes because they need to destroy pathogens with digestive enzymes.
White blood cells function as a defensive cells in the Human body and to perform this defensive duties against bacteria and other pathogens they need a lot of lysosomes. these lysosomes are contained in the vesicles that are formed when the white blood cells engulfs a bacteria and these lysosomes ( hydrolytic enzymes ) digest the pathogen, preventing the infection that could have caused by the pathogen.
Hence we can conclude that white blood cells have many lysosomes because they need to destroy pathogens with digestive enzymes
