Dave is planning to build an electric power station to supply electricity to his community. To help him decide which type of electric power station to build, he has put together the table below, which summarizes some of the advantages and disadvantages associated with different technologies.


Power Technology Advantage Disadvantage

hydroelectric no greenhouse gas emissions upsets natural ecosystems

coal inexpensive releases greenhouse gases and other pollutants

wind no greenhouse gas emissions can't always supply electricity when it's needed

solar no greenhouse gas emissions expensive to build, install, and replace

natural gas easily supplies electricity when it's needed releases greenhouse gases and other pollutants


If Dave wants to use a technology that does not directly impact climate, which of the above technologies should he consider?

A.

coal, wind, and natural gas

B.

solar, wind, and natural gas

C.

hydroelectric, coal, and solar

D.

hydroelectric, wind, and solar

Rapid glacial retreat due to climate change.

The disturbances, which can only be categorized as extreme, are the rapid glacial retreat due to climate change.

What is the glacial retreat?

The glacial retreat is when the terminal does not extend as far.

When the ice melts quicker than the snow falls, the retreat of glacial occurs.

When the glacier loses its ice more it gains, than water level rises.

Sometimes, the pieces of ice rocks float in between the water.

this is because when you cut logs they release carbon back into the air and that can be bad over time.

A human family enters a piece of land to build a cabin and their fireplace effect on biodiversity can start small and grow over time to affect large ecosystem levels. So, the correct option is D.

What is Biodiversity?

Biodiversity or biological diversity is defined as the diversity and variability of life on Earth as a measure of variation at the genetic, species and ecosystem levels. Biodiversity is explained as the diversity of all living things that are different plants, animals and microorganisms, the genetic information which they contain and the ecosystems they form.

Biodiversity is explored at three levels – genetic diversity, species diversity and ecosystem diversity. A human family enters a piece of land to build a cabin and their fireplace effect on biodiversity can start small and grow over time to affect large ecosystem levels.

how mutation cause colorectal cancer​

Answers

Answer:

A very small portion of colorectal cancers are caused by inherited gene mutations. Many of these DNA changes and their effects on the growth of cells are now known. For example: Familial adenomatous polyposis (FAP), attenuated FAP (AFAP), and Gardner syndrome are caused by inherited changes in the APC gene.

3. How can mutations benefit a species?

Answers

Answer: They can lead to speciation.

Explanation: Speciation can introduce new survival traits to a species which can lead to higher survival rate in their environment and that can lead to population growth.

Answer:

They result in specific gene variants that aid organisms in adapting to environmental changes. Beneficial mutations are required for evolution to take place. They improve an organism's chances of survival or reproduction, and as a result, they are likely to become more frequent over time.

What is PCR?

Polymerase chain reaction (PCR) is a technique used in molecular biology to replicate (amplify) a given fragment of DNA.

In this technique (PCR) primers sequences must be used to add nucleotides to the amplified DNA strands during DNA replication.

These nucleotide primers must be sequence complementary to the fragment of DNA desired to be amplified by PCR.

In this case, none of the DNA fragments can be fully generated by using these primers or any of their combinations.

Question 7(Multiple Choice Worth 4 points)
(04.03 LC)
Which process takes place in both plant and animal cells?
Conversion of solar energy
Cellular respiration
O Formation of glucose
O Photosynthesis’s

Answers

Answer:

Cellular respiration

Explanation:

Conversion of solar energy and photosynthesis require specialized equipment that animal cells just don't have. Because animal cells don't have chloroplasts, those two options are out of the question.

Animals also do not create glucose. They break down glucose and O2 into energy, H2O and CO2. Plants, on the other hand, use energy, H2O, and CO2 to create glucose and O2.

Cellular respiration is the process by which cells break down "food" into useable energy. As you can see, this happens in both plant and animal cells!
