Junior 1 Science is super simple, and Junior 1 Science is very simple

There are many genera and species in the family Compendium of Phylum.

Cell membrane (which controls the entry and exit of substances).

Cytoplasm (site of life activity).

The nucleus of the cell (which stores the genetic material of life).

(1) The main edible leaves are camellia, water spinach, spinach, cabbage, and baby cabbage.

2) The main edible stems are asparagus, spring shoots, hairy shoots, and potatoes.

3) The main edible roots are radish, carrots, mustard greens, turnips, cabbage, potatoes, and ginseng.

4) The main edible flowers are chrysanthemums, honeysuckle, cauliflower, and daylily.

5) The main edible fruits are green peppers, tomatoes, loofahs, cucumbers, bitter gourds.

6) The main edible seeds are sunflower seeds, almonds, peas, broad beans, lentils.

1.Root vegetables.

All vegetables that are eaten with fat, fleshy straight roots are root vegetables. This kind of vegetable is characterized by storage and transportation, and contains a large amount of starch or sugar, is a high calorie food by-food, in addition to making vegetables, can also be used as food industry raw materials for further processing.

The main varieties of root vegetables include radish, carrot, root mustard, turnip, cabbage, potato, sweet potato, etc.

2. Stem vegetables.

The main part of stem vegetables for human consumption is the stem. The stems are divided into above-ground stems (lettuce, stone cypress, bamboo shoots, mustard, amaranth, etc.) and underground stems (horse-sweet potato, ginger, Jerusalem artichoke, etc.). The lettuce, stone cypress and bamboo shoots in this kind of vegetables are eaten with fresh young stems, and they are easy to age and deteriorate in quality after a long time, so they can be processed into canned food for storage.

Potatoes, ginger, Jerusalem artichoke, etc. are shelf-stable and can be used all year round.

3. Leafy vegetables.

There are many types of leafy vegetables, and the varieties are also rich, and they are the main vegetables in the market. It mainly includes Chinese cabbage, Chinese cabbage, cabbage, spinach, celery, green onions, leeks, fennel, turnips, etc

The leaves of this kind of vegetables are large, fresh and tender, and have a high water content, so they are mostly eaten fresh and can also be processed and pickled.

4. Cauliflower.

There are few varieties of this type of dish, mainly cauliflower and daylily, both of which are eaten by flower organs.

5. Fruits and vegetables.

The common feature of fruit and vegetable vegetables is that they originated in the tropics, and it is the main vegetable in summer in China. The main types of fruits and vegetables are cucumbers, pumpkins, winter melons, loofahs, bitter gourds, eggplants, peppers, tomatoes, kidney beans, cowpeas, peas, broad beans, etc.

6. Seeds.

Beans such as peas, broad beans, lentils, peanuts, almonds, pines, sunflowers, wheat, and rice are the seeds that eat them.

(1) The main edible leaves are small cabbage and small green cabbage

2) The main stems that are eaten are water spinach and celery

3) The main edible roots are lotus root, ginseng, and radish.

4) The main edible flowers are daylily and broccoli

5) The main edible fruits are apples, pears, and peaches.

6) The main edible seeds are melon seeds and peanuts

7) The main edible sprouts are bean sprouts and bamboo shoots

And also... This is the physics section, you seem to have misplaced the problem...

The structures that have imaging functions are eyepieces and objective lenses. When aligning the light, on the basis of the preparation steps, turn the reflector so that the light through the light is reflected into the lens barrel, and a bright white circular field of view can be seen from the eyepiece. When the lens barrel is rotated, the structure with a large lifting amplitude is a coarse collimation spiral, and it is used with a low magnification objective or a high magnification objective in observation experiments?

Low magnification. When you do an observation experiment with a microscope, if you find a black spot in your field of view, how do you determine where it is? Please write your ** method: move the slide, if the black dot moves, it means that the black dot is on the slide, if not, then proceed to the next experiment; Rotate the eyepiece, if the small black dot also rotates, it means that the small black dot is on the medulled rock mirror, otherwise the next step of the experiment is carried out; If the small black dot disappears, it means that the small black dot is on the objective.

A cell is a three-dimensional structure, but what is observed under the microscope is also a planar view of the cell. Students A and B observed two sheets of the same animal tissue cells under the microscope. As a result, student A saw that the cells in the mount were round, and student B saw that the cells in the mount were rectangular.

Please speculate that the three-dimensional shape of the tissue cells of this animal is most likely cylindrical.

What about the figure? Shift your vision wherever you are.

1. > refrigerant.

2> (1) inside the evaporator.

2) Condenser.

I can't stand it! The answer upstairs doesn't make sense!

Low boiling point evaporator condenser

Please provide the main parameters, but according to the valid information you display, you can give the following ideas:

The average density is the mass of the phone divided by its effective volume;

Whether the hail is hollow with a covered sail can be divided by the mass of 60 kg (1000 * mobile phone volume) to obtain the density of the advertising mobile phone, if it is consistent with the density of plastic, it is solid, if it is less than plastic and megadensity, it is hollow.

Conjecture 1: Color

Conjecture 2: Floral

If the above material punching stuffiness is true, which conjecture can it verify?

Affirmed or denied? Colors are affirmed

If you want to design an experiment to verify whether the color of the flowers attracts butterflies, how are you going to control the experimental conditions.

The brightness of the colors should be different, the size, the smell, the location of the birth, etc.

How to avoid accidental factors (butterflies flying around) interfering with the experimental results.

Repeat as many times as possible

Hello! (A) should be selected

Because penicillin is a class of antibiotics that can destroy the cell wall of bacteria and play a bactericidal role in the reproduction period of bacterial cells, it is the first antibiotic that can attack human diseases.

If you don't believe it, there are references below, and the landlord may wish to take a look.

The greater the magnification of the microscope, the larger each cell will be seen, and the smaller the number of cells will be seen) Root cells do not need to photosynthesize, there are no chloroplasts).

Cats, dogs, jellyfish are animals).

Plants can photosynthesize, animals cannot).

Cats are mammals) filial piety and grandchildren.

It's all seeds) the former category will not fly, the latter will fly)

are all 0, the same temperature).

The seeds of pears have fruit outside of them, and the seeds of pine have no fruit outside of them).

Organisms can move, such as animals can run, and non-living things can also move, such as cars) ferns reproduce by spores).

The color of the coat and hat is similar to the color of the jungle, and the disguise is good for camouflage).

The item of the selection hall should be changed to "and whether the hidden seeds are wrapped in fruit peels") is now sold and not explained We are the opening of the second year of junior high school.

b. The larger the magnification of the microscope, the smaller the number of cells seen.

c. There are chloroplasts in garlic root cells.

c. Cacti and cactus are both plants.

c. Chlamydomonas, cucurbitrobon, fern, and rice are plants and not starvation chain animals on the basis of being able to carry out photosynthesis.

a. The highest is the cat.

a. The edible part of the stool mainly belongs to the apple.

d. Whether it can fly.

C, the water of 0 is as hot as the ice of 0 is compared to the temperature of the ice.

b. Compared with pines and pears, the biggest difference is whether the leaves are slender and as long as needles.

c. The common denominator between living and non-living things is movement.

a. Ferns do not belong to seed plants.

d. The color is best green.

The broth has no contact with the air.

Do a few more repeats.
