Answers

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

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.

Answers

Solar radiation is absorbed or reflected as it travels to the earth's surface.

Solar Radiation

When 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.

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.

Answers

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.

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?

Answers

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

Cattle’s are fattened up and kept in horrible living conditions. Chickens often have half their beak removed because of the crowded living conditions. Pigs are kept in such horrible living conditions that they’re already dying before getting slaughtered.


Explanation:

Chickens are kept in such crowed condition that half of their beaks are removed lest they peck each other to death. Cattle are fattened up in feedlots where they are kept in crowed and filthy conditions; often their feet are rotting before they get to slaughter. Pigs too are kept overcrowded and in cages. Factory farming is NOT your grandfather’s farming methods, and those of us who object to it are not sentimental fools, as one writer here would have you believe. The animals are really abused. They are so crowded many of them would die if they were not routinely given antibiotics in their food, which why we have so many antibiotic resistant bacteria these days. Not every farmer keeps animals this way. If you like eating meat, milk, and eggs, it is possible to find them raised in healthy, humane, and sustainable ways. The products will be more expensive, but are usually tastier and of better quality. The worst abusers are surprise the big corporations pushing for profit at any cost.
