In biology, the system is big or the tissue is cleaned

Cells are smaller than tissues, smaller organs, and smaller systems.

21+x=2(12+15-x)

3x=33x=11 There are 11 people who go to the library.

Similarly: 21+x=2(12+11-x).

3x=25 x no integer solution so it is not feasible.

21 + 15 = 36 (people).

32-21=11 (person).

Answer: 11 people should be transferred.

15-4=11 (people).

21 + 12 + 11 = 44 (people) is not divisible by three because the ratio of people who go to the lab to the number of people who go to the library is 1:2

A: No, you cannot.

Delineate the health responsibility area, which is divided into personal responsibility area and public responsibility area, and each person is responsible for ensuring that the personal area is clean and tidy every day, in line with the 5S standard, and is inspected from time to time. Common areas (floors, partitions, garbage, toilets, etc.) are cleaned regularly by cleaning staff.

Personally, I don't advocate employee cleaning, employees don't work during working hours, and it's too expensive to use for cleaning. The company does not have the right to occupy the off-duty hours. And this kind of cleaning is generally not very effective. This is an era of specialization, and special people should be in charge.

This is 5S management. Cleaning every day, once a week* (Wipe glass partitions.) I take charge of the area separately, and the person who does not participate deducts ten people from the salary and rewards cleaning.

In short, no one is missing, and all employees participate, including leaders. It's not hard to get into a habit and put it into practice.

Finally, the leader conducts a 5S inspection of each department.

pPlanning stage: preparation work, such as cleaning tools, division of labor (floor, partition, tables and chairs), safety protection, etc.;

D implementation stage: cleaning mobilization - clear cleaning discipline - explain the completion period - implementation of cleaning C inspection stage: according to the inspection benchmark done in advance, evaluation.

Finally, the PDCA cycle again.

Solution: Set up a transfer to Tudou Chun Dig Bookstore x people.

21+x=〔12+(15-x)〕*2

21+x=54-2x

x+2x=54-21

3x=33 x=11

Solution: Set up a transfer to the library x person air core.

21+x=〔12+(15-4-x）〕*2

21+x=46-2x

x+2x=46-21

3x=25x=25/3

No, because the number of people is not 25 3

1.The class leader wants to make the number of people who go to the library exactly double the number of people who go to the laboratory. Then the whole number of people is divided into three parts, 2 for the library and 1 for the laboratory.

4 people should be transferred to Keeda Min's library.

2.No, because only if the number of people everywhere is a multiple of 3 can the relationship be met with the number of people going to the library exactly twice the number of people going to the laboratory. 4 people is not a multiple of 3, and there is no way for people to turn it away.

A system is the whole thing, and an organization is just a part of it.

Organs are made of tissues, so organs are larger than tissues, and systems are made of organs, so the system is bigger. The order of their size is: from largest to smallest, systems, organs, tissues.

Similar by morphology, structure. The cell group formed by cells with the same function is called tissue, which is composed of different tissues in a certain order to form a structure with a certain function, called an organ.

A system is called a system in which multiple organs with different functions are combined in a certain order to form one or more physiological functions.

So the system is larger than the organ and larger than the tissue.

The organs are large, and the tissues make up the organs; There are, for example, the digestive system, which is made up of several organs, so it is larger than the first two.

Organs are large Organs are organized and systematic, and the system is the largest in the first year.

On September 25th, our class had a big cleaning.

After a while, the teacher came in, and the students listened to the tasks assigned by the teacher like conscripted soldiers, and after receiving the tasks, they did what they said, and the classroom immediately boiled, I was chopping grass, and I saw the dust in the school flying everywhere, and I really didn't know where to start. Some of the students were wiping the blackboard, some were mopping the floor, and some were cleaning the glass. Everyone scrambled to do it, and I came out right away, to my destination, the playground.

A few of us got up and running quickly, and at this point, if you're standing a little higher, it's really hot and energetic. You see that the student took two shovels, quickly left and right, very fast, in a moment he cut down such a large piece, and the cut was so clean, he was like a cleaning machine, so fast and so clean. Look at Ma Liang, don't look at him small, he can do his work without ambiguity and quickly.

Look at the two female students who are sweeping the playground here, they divide the playground into several areas, and then wave the broom, sweep the area into a pile, and clean it up. Looking at it now, the whole playground is like a clean carpet, and the students can exercise happily on the playground again.

I came to the classroom and saw the dust flying everywhere, and I really didn't know where to start to help them. Some of the students were wiping the blackboard, some were mopping the floor, and some were cleaning the glass. Look at!

Yu Xiaoqin, who was wiping the table, looked at the pen water on the table, at this time, she rolled her eyes, took a little laundry detergent and a basin of water, she first sprinkled a little laundry detergent on the table, then sticked a little water, wiped it with a rag brush, and immediately, the pen water disappeared from the table immediately, although she was tired and sweaty, but she also showed a smile on her face. I saw that there were more and more clutter on the ground, so I said to Yang Xiaoyan, "You go and pour it."

He saluted me like a soldier to his commander and ran away, and I watched him out of the window.

After a while we came to the woods in front of the school gate to shovel the grass, and our classmates quickly began to cut the grass and eradicate the roots, and soon we were done, and we saw that the original woods overgrown with weeds were now very clean.

Through our efforts, the "garbage dump" just now has been changed by us. Seeing this, everyone felt very happy.

The Spring Festival is the traditional festival of the Chinese nation, and it is also the most solemn festival. At the end of every month, every household has to be cleaned. Prepare for a clean and festive holiday, and my family is certainly no exception.

After breakfast that day, my mother put on an apron and stood on a chair to clean the windows with a rag and toilet paper. Seeing my mother's tired and sweaty appearance, I wanted to help my mother, "Mom, can I help you clean the windows?" Mom said, "Thank you, I'm glad you can think of helping Mom, it's a bit dangerous to clean the windows, it's an adult's job, you're still young, let's go play."

No, I'm going to wipe it. "Mom couldn't help it, so she asked me to clean the bottom half of the window. So I got toilet paper and started cleaning the windows, which were still a mess.

How so? I carefully watched my mother's window cleaning process, and it turned out that I had to use a damp rag to wipe off the dust from the window, and then use toilet paper to dry the water on the window. I followed my mother's steps and he wiped it carefully, and the window was clean and bright.

I happily asked my mother, "Did I wipe it clean?" "It's okay.

Mom looked at it and said. "It's very clean. Dad praised on the side.

I knew my dad was encouraging me.

Through the efforts of the whole family, my home has become cleaner. There's a good way to do anything, and the way I learned to clean windows isn't bad.

The New Year is coming, and my mother said, "Why is there such a mess at home today!" It's time for a family cleaning.

Mom immediately assigned cleaners to every part of the house. Mom asked me to clean my own room and Dad to clean my bedroom and living room. And she cleans the bathroom, the kitchen, the hallway.

After my mom assigned everyone's tasks, she announced that the cleaning had begun, and I was the most relaxed, just tidy up my toys, wipe down the table and chairs, sweep the floor, and that's it! After I did all this, I thought what happened to my dad's side. I'll have to take a look.

When I got to my father's side, I saw him cleaning unhurriedly, and after my father finished cleaning, my father and I thought about what happened to my mother's side? We'll have to see. My dad and I saw that my mom was tired and thirsty and still working.

We decided to help her, so we said to her, "Let's help you!" Mom said

All right! "We cleaned Mom's room together. I was tired but happy because I had done a good thing by helping my mother.

The New Year is coming soon, and it is our traditional habit to remove the old and welcome the new, so today our family decided to do a thorough cleaning. Usually, I don't have anything to do with cleaning at home, but today my mother wants me to be in charge of this family cleaning. There's no way, anyway, the initiative is in my hands, so I'll be partial and do some easy work by myself!

So, I cleared my throat and said loudly: "Dad is responsible for cleaning the windows, Mom is responsible for cleaning the bathroom, Grandma is responsible for tidying up the kitchen, Grandpa mopping the floor, I'll just wipe the table!" ""Okay, just listen to my granddaughter's arrangement, just do it!

Grandma happily rolled up her sleeves and walked into the kitchen, and her mother also took a scouring pad into the bathroom and brushed the bathtub. Dad and grandpa are also in place. "Whew-Whew-Whew" is the song made by the vacuum cleaner when it "enjoys a good meal"; "Brush-brush-brush" is that the mother is brushing the wall tiles vigorously; And I'm scrubbing the rag with "whoa-whoa-whoa", it's really a family mobilization!

The work I had assigned to myself was really easy, and I was done in a few moments. I just wanted to play with the computer for a while, but when I saw that my parents were still buried in their work, I was embarrassed: how could I be so selfish and choose light work.

When I saw my dad climbing up to the windowsill to clean the windows, and then jumping off to rub the rag, I was very busy, so I volunteered to help my dad rub the rag. When Dad and I finished cleaning the windows, Dad helped Grandpa mop up the floor, and I, of course, also acted as Grandma's little helper. Look at!

How much we love each other as a family!

Originally, the house was very dirty, but after the labor of our five hands, it suddenly became so clean. We experienced the fruits of our labor and smiled happily!
