Skin has three layers: The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
The skin has three main functions: Protection; Thermoregulation; Sensation.
The skin acts as a protective barrier from:
Mechanical, thermal and other physical injury;
Harmful agents;
Excessive loss of moisture and protein;
Harmful effects of UV radiation.
The newly formed skin have the following features:
Contains newly formed keratinocytes.Appears pinkish and delicateMelanocytes are few.Do not have hair folliclesThe normal patch of skin on the other hand:

In biology
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.

Answer:
A pH scale measures how acidic or basic a substance is.
Explanation:
The pH measures the H+ concentration in a substance. The more lower the pH, the more acidic the substance, the higher the pH, the more basic the substance. It measures from 0-14, with 7 being neutral. Anything less than 7, acidic. Anything above 7, basic.

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.

In the Northern Hemisphere, choose ALL that apply
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.

Answer:
Differences in air temperature cause movement in the air, which creates pressure.
The radiant energy from the Sun is transferred to the atmosphere, causing air movement. The air becomes less dense, so it rises.
As the air falls, it becomes more dense and cools to Earth’s surface.
The higher the latitude, the colder the climate; the lower the latitude, the hotter the climate.
Why do light-fur mice survive LESS often on dark rocks, compared to dark-fur mice?
Answer:
for a creature with a lighter fur color it is next to impossible to blend into darker colored environments compared to darker fur colored creatures
The light fur mice survive less on the dark rocks compared to the dark fur mice. The reason is the light fur mice can be easily visible by the Predator and eaten by them.
What is adaptation?An adaptation is a process in which an organism tries to adapt with the environment in order to protect itself from the predator. There are different types of adaptation seen in the animal kingdom, such as mimicry.
An example is mice fur coloration on the dark rocks. Dark rocks have dark coloration. When dark-furred mice live on this type of rock, their colour will mix with the dark colour of the rock. As a result, they can't be clearly visible to the predator's eye. Predators that are present at a distance, such as birds can't distinguish between the rock and the dark mouse's fur. This increases their chance of survival. When a light fur-colored mouse lives on the dark Rock, it can easily be differentiated by the Predator and eaten by them.
Hence, light colour fur mice survives less than the dark fur mice on the dark Rock as they can easily be seen by predators.

Which statement is the best prediction the students can make about the immediate future of the pond?
A) The depth of the water in the pond will increase.
B) Fish populations in the pond will begin to decrease.
C) The amount of bacteria in the pond will suddenly decrease.
D) The number of different types of plants around the pond will increase.

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.
