✯Hello✯

↪  Genes are the things that are a part of our DNA who that make up who we are and what we look like

↪  Genes have bases which change the structure of everyone's DNA that makes everyone look different

↪  Genes are A part of the double helix structure

↪  If you have any more questions feel free to ask :) Hope this helps

ENERGY PYRAMIDS
Natasha2012 [34]

Answer:

Energy is lost at several levels from the body of an organism. Two of the phenomenons through which energy is lost are

Conduction:

When a body is in contact with another body, energy is lost in the form of heat. For example, if we sleep on a cold floor, energy from our body would be lost to the floor in the form of heat,

Decomposition:

Energy is lost when cells in a body die and energy is required for decomposition also.

How does the carbon cycle affect climate change and global warming on our planet? (Think about the different ways that carbon is
Lilit [14]

Answer:

Explanation:

The amount of global warming will depend on the magnitude of future emissions, which, in turn, depends on how society grows and develops. The rate of warming will also depend on how sensitive the climate is to increased atmospheric greenhouse gases.

Yet climate change also depends on an under-appreciated factor known as “carbon-cycle feedbacks”. Accounting for uncertainties in carbon-cycle feedbacks means that the world could warm much more – or a bit less – than is commonly thought.

The carbon cycle is the collection of processes that sees carbon exchanged between the atmosphere, land, ocean and the organisms they contain. “Feedbacks” refer to how these processes could change as the Earth warms and atmospheric CO2 concentrations rise.

The commonly used warming projections – those highlighted in Intergovernmental Panel on Climate Change (IPCC) assessment reports – include a single best-estimate of carbon-cycle feedbacks. But they do not account for the large uncertainties in these estimates.

These uncertainties are “one of the dominant sources” of divergence between different model projections, according to Dr Ben Booth and colleagues at the Met Office Hadley Centre.

Climate campaigners, such as Greta Thunberg, have also expressed concern that climate projections typically do not fully incorporate the potential range of carbon-cycle feedbacks.

This article explores the implications of carbon-cycle feedback uncertainties by examining a number of modelling studies conducted by scientists over the past decade. These studies give a similar central estimate of carbon-cycle feedbacks to those used in IPCC projections.

But, at the high end, the results show these feedbacks could push atmospheric concentrations of greenhouse gases much higher – meaning more warming – from the same level of emissions.

Analysis for this article shows that feedbacks could result in up to 25% more warming than in the main IPCC projections.

Importance of carbon-cycle feedback uncertainties

Today, around half of the CO2 emitted by humans remains in the atmosphere, with the remainder absorbed by the oceans and land. However, as the Earth warms this is expected to change. For example, warming reduces the amount of CO2 absorbed by surface ocean waters and the amount of carbon sequestered in soils. It can also accelerate tree death and the risk of wildfires. Thawing permafrost may release additional carbon into the atmosphere. Overall, the carbon cycle is expected to weaken as a result of climate change, leading to more emissions remaining in the atmosphere and less being absorbed by the land and oceans. All of these processes introduce uncertainty when translating future CO2 emissions into changes in atmospheric CO2 concentrations.

Changes in carbon cycle behavior as the Earth warms is an example of a climate feedback – a self-reinforcing change to the Earth’s temperature from a secondary factor. Not all of these feedbacks will necessarily act to increase temperature, however. CO2 fertilisation effects can lead to additional vegetation growth, sequestering more carbon. Nitrogen cycle changes can also enhance land uptake of carbon. Dynamic vegetation changes in response to a warming climate – which account for potential vegetation shifts as regional climate change – also have important, but uncertain effects on the carbon cycle.

What evidence does the dische test provide that helps confirm that dna was extracted from the strawberries. Why do you think it
vfiekz [6]

Ripe strawberries are an excellent source for extracting DNA because they are easy to pulverize and contain enzymes called pectinases and cellulases that help to break down cell walls. And most important, strawberries have eight copies of each chromosome (they are octoploid), so there is a lot of DNA to isolate.

What does DNA extracted from a strawberry look like?

Observe the line between the strawberry mixture and the alcohol. You will notice a white thread-like cloud appearing at this line. This is strawberry DNA. The DNA will clump together and float to the top of the alcohol layer.

What is unique about strawberry DNA?

Strawberries yield more DNA than any other fruit because they have eight copies of each type of chromosome. The long, thick fibers of DNA store the information for the functioning of the chemistry of life. DNA is present in every cell of plants and animals.

We intention extract DNA from fruit to investigate how it examines and feels. This procedure is identical to what scientists have to do before they can use the statement contained in this DNA. This announcement can be used to enhance crops so that they are more resistant to infection, insect invasion, or differences in climate.
