Answer:
The innate or nonspecific immune system includes two lines of defense in the human body. Non-specific means that it does not act on the specific pathogen. It works equally to keep all types of pathogens such as bacteria, viruses, parasites et cetera out of the body. The first line of defense includes physical barrier which prevents the entry of pathogens into the body. It includes skin, respiratory tract, gastrointestinal tract, cilia, nasopharynx, eyelashes, and body hairs.
The second line of defense includes anti-inflammatory responses, fever, and nonspecific cellular responses such as phagocytes, macrophages, complement system et cetera. Thus, the virus has to pass physical, chemical, and nonspecific cellular responses of the body in order to infect the body.

The antiviral defense is composed of changes in cells that prevent viral replication and increase susceptibility to death by lymphocytes.
What innate defense mechanism against viruses?Viral replication interferes with protein synthesis and cell function and leads to injury and death of the infected cell. The main mechanisms of innate immunity against viruses are inhibition of type I interferon infection and NK cell-mediated destruction of infected cells.
With this information, we can conclude that the antiviral defense is composed of alterations in the cells that prevent viral replication and increase the susceptibility to death by lymphocytes, thus eliminating the reservoirs of viral infection.

Why is it impossible to go to the past?
Answer:
The bending of space-time causes objects to move on a curved path and that curvature of space is what we know as gravity. Mathematically one can go backwards or forwards in the three spatial dimensions. But time doesn't share this multi-directional freedom.Explanation:

Answer:
Definition (http://en.wikipedia.org/wiki/Saprophytism) Saprotrophic nutrition is a process of chemoheterotrophic extracellular digestion involved in the processing of dead or decayed organic matter. It occurs in saprotrophs or heterotrophs, and is most often associated with fungi, for example Mucor and Rhizopus. (
Explanation:
Answer:
Saprophytism occurs in fungi and bacteria known as saprophytes.They obtain organic foods from dead organisms.They digest the complex organic food outside their bodies and absorb the simple organic substances produced.

Neutral atoms of each element contain an equal number of protons and electrons. The number of protons determines an element's atomic number and is used to distinguish one element from another.
Based on graph 1, do you think the changes in solar intensity are a significant cause of the trend in global temperatures? Why or why not?
Answer:
Changes in solar intensity do not seem to contribute to the change in global temperatures. If they did, the temperatures would rise and fall with the Sun's energy. Instead, the global temperatures continue to rise despite the Sun's natural fluctuations.
Explanation:
Human activity is the main cause of climate change. People burn fossil fuels and convert land from forests to agriculture. Since the beginning of the Industrial Revolution, people have burned more and more fossil fuels and changed vast areas of land from forests to farmland.
No, because the increase in temperature on earth is mainly related to global warming generated by the release of greenhouse gases and the release of CO2 into the atmosphere.
Explanation:
It is by action of man not because of the solar intensity

this type of tissue has excellent ability to regenerate contains many nerve but has no blood supply
Answer:
there u go
Explanation:
As living beings that encounter every kind of traumatic event from paper cut to myocardial infarction, we must possess ways to heal damaged tissues. While some animals are able to regrow complete body parts following injury (such as the earthworm who grows a new head following bisection), humans are sadly incapable of such feats. Our means of recovery following tissue damage consists largely of repair rather than pure regeneration. Thousands of times in our lives, a meticulously scripted but unseen wound healing drama plays, with cells serving as actors, extracellular matrix as the setting and growth factors as the means of communication. This article briefly reviews the cells involved in tissue repair, their signaling and proliferation mechanisms and the function of the extracellular matrix, then presents the actors and script for the three acts of the tissue repair drama.
Key words: tissue repair, regeneration, scarring, wound healing, growth factors, extracellular matrix, stem cells

I believe that the answer you are looking for is letter D, 11.0 grams/milliliter.
Solution/Explanation:
Writing out the formula for the density, using mass and volume,
D=m/v
Substituting the given values of the variables,
D=33.0 grams/3.0 milliliters
33÷3=11.
So, therefore the final answer is the letter D, 11.0 grams/milliliter.
I hope that this has helped you. Enjoy your day, and take care.
Which one of the following aspects is an exclusive characteristic of living things? (A) Isolated metabolic reactions occur in vitro. (B) Increase in mass from inside only. (C) Perception of events happening in the environment and their memory. (D) Increase in mass by accumulation of material both on surface as well as internally

What can happen to solar radiation when it enters Earth’s atmosphere?
It is increased as it hits the clouds.
It is absorbed or reflected as it travels to Earth’s surface.
It is changed into visible light.
It is destroyed by the water molecules in the atmosphere.
Solar radiation is absorbed or reflected as it travels to the earth's surface.
Solar RadiationWhen solar radiation enters the earth's atmosphere, the rays travel and hit the ground.
Some of the rays are absorbed by the ground while the rest are reflected back to the atmosphere.
Some of the reflected rays are absorbed by a layer of gas (greenhouse gases) that forms a blanket in the atmosphere while a tiny portion returns back into space.

In order for cells to function normally, they need to be in a(n) ____ solution.
hypotonic
isotonic
hypertonic
Cells should not be placed in solution.
Answer:
All living cells need energy to function in order for the chemical reactions occurring in the cells to take place. In humans this energy is obtained by breaking down organic molecules such as carbohydrates, fats and proteins.
Answer:
isotonic
Explanation:
In biology, some cells must be maintained in an isotonic solution to support cellular functions

By performing photosynthesis, plants create everything they need to build all biomolecules. Is
this true? Why or why not? (1 point)
This is true because photosynthesis produces glucose, and plants only need
sugars, not amino acids or fatty acids.
This is not true because plants need to sequester nitrogen from the soil to
build amino acids.
This is true because photosynthesis produces glucose, which has carbon,
hydrogen and oxygen-the building blocks for all biomolecules.
This is not true because plants need to perform cellular respiration to break
down the glucose into carbon, hydrogen, and oxygen.
Answer:
This is not true because plants need to sequester nitrogen from the soil to build amino acids.
Explanation:
This is the answer i got on my quiz
This IS NOT TRUE because plants need to sequester nitrogen from the soil to build amino acids.
Carbon (C), Hydrogen (H), and Oxygen (O) are building blocks of carbohydrates. Plants must obtain Nitrogen from the soil, as well as phosphorous (P) and sulfur compounds (among other critical compounds), to sustain life.For example, DNA and proteins, which are critical biomolecules to sustain life, are composed of Nitrogen (N).Amino acids are the building blocks of proteins.In conclusion, the statement above IS NOT true because plants need to obtain Nitrogen from the soil to build amino acids.
