what differences between physical and chemical barriers
Answer:
Mechanical barriers — which include the skin , mucous membranes , and fluids such as tears and urine — physically block pathogens from entering the body. Chemical barriers — such as enzymes in sweat , saliva , and semen — kill pathogens on body surfaces.
Physical barriers and chemical barriers are two types of barriers in the immune system. These barriers help prevent the entry of pathogens into the body. There are differences between physical and chemical barriers.
Physical barriers are physical structures that prevent the entry of pathogens into the body. These barriers include the skin, mucous membranes, and cilia. The skin is the most significant physical barrier. It covers the entire body and serves as a barrier against pathogens. The skin has a few layers that prevent the entry of microbes.
Additionally, the skin has sebaceous and sweat glands that produce sebum and sweat, respectively. These secretions have antimicrobial properties. Mucous membranes are another physical barrier. They line various parts of the body, such as the respiratory tract, gastrointestinal tract, and reproductive system.
They secrete mucus, which traps microbes and foreign particles. Cilia are hair-like structures that line the respiratory tract. They move in a coordinated manner and help remove microbes from the respiratory tract.

living things are made up of cells
support the statement with evidences
Answer:
True
Explanation:
1 - All living cells do indeed divide through mitosis, meiosis, or binary fission. Look at how we’re created through our cells merging in meiosis, how our skin cells replicate and divide in mitosis, and how bacteria replicates in binary fission. However, we question this by asking where the first cells came from (if you aren’t religious, at least).
2 - All living things are made up of at least one cell, the smallest ones being prokaryotes.
3 - A cell does hold all the functions of life on its own, as we define the functions of life through MRHGREN (metabolism, respiration, homeostasis, growth, reproduction, excretion, and nutrition). However, we can question this by looking at viruses as they are smaller, yet are not considered living as they need to have a host cell in ordered to perform the functions.
Yes, living things are made up of cells.
Evidence to support the statement:Living organisms are made up of cells. Cells are the structural and useful units of all living organisms. In 1665, Robert Hooke determined the lifestyles of cells through the use of the microscope, which in addition paved the way for the invention of various different microscopic organisms.
Why cells are called cells?
A cell is the simple unit of lifestyle as we know it. it is the smallest unit able to the impartial replica. Robert Hooke counseled the name 'cell' in 1665, from the Latin cella that means storeroom or chamber, after using a very early microscope to observe a piece of cork.

4. Compare how decomposers work in the natural environment to what happens in a compost bin.
Answer:
All of the decomposer organisms in the compost ecosystem are linked by a “what eats what” food web, wherein organisms are classified according to what they eat.
Explanation:
Anaerobic decomposition takes place in nature, as in the decomposition of the organic muds at the bottom of marshes and in buried organic materials to which oxygen does not have access. Intensive reduction of organic matter by putrefaction is usually accompanied by disagreeable odors of hydrogen sulfide and reduced organic compounds which contain sulfur, such as mercaptans (any sulfur-containing organic compound).
When organic materials decompose in the presence of oxygen, the process is called “aerobic.” The aerobic process is most common in nature. For example, it takes place on ground surfaces such as the forest floor, where droppings from trees and animals are converted into a relatively stable humus. There is no accompanying bad smell when there is adequate oxygen present.
Aerobic oxidation of organic matter produces no objectionable odor. If odors are noticeable, either the process is not entirely aerobic or there are some special conditions or materials present which are creating an odor. Aerobic decomposition or composting can be accomplished in pits, bins, stacks, or piles, if adequate oxygen is provided. Turning the material at intervals or other techniques for adding oxygen is useful in maintaining aerobic conditions.

One observation that scientists made was that the willow population increased as the elk were forced to forage in more varied areas to avoid
wolves. This resulted in the beaver population increasing, as they had more resources to build dams to provide shelter through the winter. What
other effect would you expect to see?
A) Beaver population will decrease, because more dams will reduce the number of willows,
OB) Ek will increase in population, since the willow population has increased.
C) Migratory fish populations will decrease, because dams prevent them from returning upstream to mate.
D) Wolves will increase in population, because elk are not eating as many willows
Answer:
I think I would say C
Explanation:
I say C since it couldn't be B since the beaver population increased, not decreased
I feel like it wouldn't be D either since it doesn't really make sense. Wolves weren't affected when the Elk population decreased.
I wouldn't say B either since it said that the Elk population decreased because of the willows.

Which of the following statements is accurate?
A: You can never get more energy out of a system than you put into a system.
B: The energy out of a system is always MORE than the energy input.
C: The energy out of a system is always EQUAL to the energy input.
Answer:
C
Explanation:
energy cannot be created nor destroyed; the same amount of work or energy you put in something, the same you're gonna get back, however all of it you cannot use because it will transferred to other forms of energy also. Therefore, the amount cannot be more or less, so it would have to be equal.
(Technically A is also correct but C is more precise so I'd assume C would be the superior answer)
Answer:
the CORRECT answer is A. You can never get more energy out of a system than you put into a system. <3
Explanation:
a volcano with thick viscous lava would most likely have which eruption
a - intrusive
b - explosive
c - metamorphic
d - gentle
Answer:
B. Explosive eruptions
Explanation:
An eruption of highly viscous (very sticky) magma tends to produce steep-sided volcanoes with slopes that are about 30–35°.
Explosive eruptions generally involve magma that is more viscous and has a higher gas content. Such magma is often shattered into pyroclastic fragments by explosive gas expansion during an eruption. Volcanic eruptions may fall into six major types: Icelandic, Hawaiian, Strombolian, Vulcanian, Pelean, and Plinian.
