Answer:
A - it gives them their shape
Explanation:
Bacteria need a cell wall to help maintain their shape
- the cell wall is more stable and sturdy than a cell membrane
The other two answers are incorrect:
- the cell wall has no impact on the color of a bacteria
- the cell wall does not necessarily prevent the cell from bursting as the bacteria is still able to be burst by different cells of the immune system (ex. macrophages)
However! the cell wall does provide some protection to the bacteria as it protects the DNA inside the bacterium from being exposed to harsh environments outside of the cell. but since this isn't an option, A is the correct answer. (but you should probably still be aware of what else the cell wall does)

Dylan wants to observe some onion cells with a microscope. He places the cells on a slide. Describe how Dylan uses the microscope so he can see the cells with a ×20 objective lens.
Answer:
See the answer below
Explanation:
After routinely cleaning the microscope and ensuring that all the parts are working fine, Dylan would have to place the slide on the stage of the microscope, switch on the light source, and adjust the diaphragm of the condenser to ensure that adequate light gets to the slide on the stage.
Thereafter, Dylan would need to turn the revolving nosepiece in order to shift to the lowest objective of the microscope assuming it is not already in place. Then, the slide on the stage is brought into focus (by viewing through the eyepiece/ocular) by using the coarse/fine adjustment knob to bring the stage up/down.
Once the slide is brought into clear focus, the revolving nosepiece is then turned to switch the x20 objective. Generally, at higher objectives, the coarse adjustment knob is rarely needed and the fine adjustment knob is solely used instead to bring the slide back into focus. Thus, Dylan can see the cells of the onion at the desired objective.

All animals need food, water, shelter, and space to live. which of these is difficult to find in a grassland habitat?
According to the scenario, it is difficult to find shelter in a grassland habitat. This is because grassland habitat generally consists of small grasses with a lack of space between them.
What is Habitat?Habitat may be defined as a type of natural environment for which a particular species is best adapted due to natural selection. It may also be characterized as the area where the basic demands of an organism are fulfilled like food, water, space, mating partner, etc.
Grasslands habitats are generally open and continuous, fairly flat areas of grass. They are often located between temperate forests at high latitudes and deserts at subtropical latitudes. In these habitats, the availability of shelter is very low because of an abundance of small grasses across the area which is insufficient to build a shelter.
Therefore, it is difficult to find shelter in a grassland habitat. This is because grassland habitat generally consists of small grasses with a lack of space between them.

Why does DNA look like a folded thread? HELP ME PLEASE!!!!
Answer:
During DNA packaging, long pieces of double-stranded DNA are tightly looped, coiled, and folded so that they fit easily within the cell. Eukaryotes accomplish this feat by wrapping their DNA around special proteins called histones, thereby compacting it enough to fit inside the nucleus

Fall and Spring Equinoxes occur when days and nights are equal in length.
Summer solstice occurs when the Earth's North Pole is tilted toward the sun.
Winter solstice occurs when the Earth's North Pole is tilted away from the sun.
The tilt and revolution of the Earth causes the seasons
answer: Summer solstice occurs when the earth NORTH POLE is tilted in longest day.
Winter solstice occurs when the earth North pole is tilted shortest day
Explanation: took the test got an A
According to the Northern Hemisphere, all the statements given are exactly true.
What is the Northern hemisphere?It is one-half of the earth that is located in the north of the equator. It has about 90 percent of the world's population and most of the world's land.
Equinox means the duration of day and night are equal in length. There are two equinoxes in a year when the sun moves across the celestial equator, which lies directly above the earth's equator. The summer solstice occurs when the earth's pole is tilted towards the sun and receives more sunlight in the northern hemisphere. Winter solstice occurs when the earth's north pole is tilted away from the sun and receives less sunlight. Overall, the tilting and revolution of the earth is the main reason for the causation of different seasons.
Therefore, all the given statements are true with respect to the northern hemisphere.

Static frictional force is the minimum force that must be overcome for one object to slide over another.
What is frictional force?Frictional force is the force the acts between the surfaces of two objects in contact which oppose the motion of one object over the other.
The minimum force that must be overcome for one object to slide over another is known as static frictional force.
If the applied force is greater than static frictional force, the object will start moving over the other.
Therefore, static frictional force is the minimum force that must be overcome for one object to slide over another.

The amount of Cytosine plus Guanine is 40%. What would be the amount of Adenine?
Answer:
30%
Explanation:
Considering that the amount of Cytosine added to the amount of Guanine is 40%, that explains that Cytosine and Guanine each equal to 20%.
Cytosine: 20%Guanine: 20%Now, the remaining bit is 60%. Since Adenine and Thymine both equal the same, that would mean: 60/2 = 30.
Adenine: 30%Thymine: 30%Cytosine and Guanine pair together and will always be equal to one another. The same goes for Adenine and Thymine. (A=T, C=G)
Always remember that you want it to total up to 100% at the end.

Why solid melt when heated
Answer:
When a solid is heated the particles gain energy and start to vibrate faster and faster. Further heating provides more energy until the particles start to break free of the structure. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid.
