The real length of one villus is 0.8 mm
Calculate the image length if the villus is viewed at a magnification of x20

magnification = size of image / size of real object

Answers

Answer:

Explanation:

Re arrange formula=Size of image=Magnification*size of real image

0.8mm*20=16mm

The image length will be "16 mm". A further explanation is below.

Given:

Magnification,

20

Size of real image,

0.8 mm

As we know the formula,

→ [tex]Magnification = \frac{Size \ of \ image}{Size \ of \ real \ image}[/tex]

or,

→ [tex]Size \ of \ image=Magnification\times Size \ of \ real\ image[/tex]

By substituting the values, we get

→                         [tex]=20\times 0.88[/tex]

→                         [tex]= 16 \ mm[/tex]  

Thus the response above is correct.

Identify the bonds formed between RNA nucleotides by RNA polymerase.

A. Ester
B. Glycosidic
C. Peptide
D. Phosphodiester​

Answers

Answer:

D. Phosphodiester​

Explanation:

Just as the DNA polymerase serves as a catalyst in the replication of the DNA, so does the RNA polymerase speed up the formation of the RNA. RNA polymerase performs its function of linking nucleotides when the phosphodiester bonds are formed in the 5' to 3' sequence. Nucleoside triphosphate precursors such as the Adenosine triphosphate, Cytosine triphosphate, and Guanosine triphosphate serve as the substrates that allow the formation of the RNA molecule.

When the RNA polymerase unwinds the double helix structure of the DNA found before the active site where the polymerization will occur, substrates can then pair themselves in a complementary form.

Which of the following is NOT one of the Nervous System Functions?. Single choice.
(1 Point)

1.To detect changes and feel sensations

2. To initiate appropriate responses to changes

3. To organize information for immediate use and store it for future use

4. Absorb extra fluid between the cells

Answers

Answer:

4. Absorb extra fluid between the cells

Explanation:

The nervous system (SN) is a complex system that acts to receive sensory information through nerves, transmit this information via the spinal cord and finally process it in the brain. The SN has three main roles: sensory input, processing and motor output. The SN can be divided into the central nervous system (composed of the brain and spinal cord), and the peripheral nervous system (composed of those nerves located outside the brain and spinal cord). Moreover, the extracellular fluid between the cells comprises four types of fluids: 1-intravascular fluid (blood), 2-interstitial fluid, 3--transcellular fluid and 4-cerebrospinal fluid. The excess of these fluids is absorbed by the capillaries of the lymphatic system.

4. Define carbon sequestration and explain how deep geologic burial of carbon works.
5 Describe the connection between fossil fuel burning, the melting of polar ice, and the rising of global sea levels.

Answers

Answer:

1. The enhanced greenhouse effect disrupts the Earth's climate equilibrium and has led to an increase in the global average surface temperatures.

2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"   1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.

3. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere. Less heat radiates into space, and Earth is warmer. ... Carbon dioxide, methane, water vapor, and nitrous oxide are naturally present in Earth's atmosphere.

4. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change.

5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. ... Scientists have found that water draining from melting glaciers and ice sheets in polar and mountain regions is now also contributing to this rise in sea levels.

Answer: 1. Necessary because it keeps heat in and keeps the planet at the right temperature for life.

It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming. 2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth's climate comfortable when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. 3. Human activities contribute to global warming by increasing the greenhouse effect. ... Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. 4. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change. Geologic carbon sequestration is the process of storing carbon dioxide (CO2) in underground geologic formations. The CO2 is usually pressurized until it becomes a liquid, and then it is injected into porous rock formations in geologic basins. 5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. This expansion in turn causes sea levels to rise. ... There is now so much warming baked in to the global climate system that sea levels will continue to rise for centuries.

Into what kingdom would each of the following be classified: Unicellular prokaryotes that live in dust. ______________________ Unicellular eukaryotes that line in pond water. _____________________ Multicellular eukaryotes that live all over the planet and consume food. ______________________ Unicellular prokaryotes that live in volcanic ash. _________________________ Multicellular eukaryotes that have cell walls and are heterotrophic. _______________________ Multicellular eukaryotes that have cell walls and are autotrophic. ________________________

Answers

Answer:

Unicellular prokaryotes that live in dust: Eubacteria

Unicellular eukaryotes that line in pond water: Protista  

Multicellular eukaryotes that live all over the planet and consume food: Anamalia  

Unicellular prokaryotes that live in volcanic ash: Archaebacteria  

Multicellular eukaryotes that have cell walls and are heterotrophic: Fungi  

Multicellular eukaryotes that have cell walls and are autotrophic: Plantae

Explanation:  

Prokaryotic organisms can be classified into two groups: Eubacteria and Archaebacteria. Eubacteria (i.e.,“true” bacteria) are unicellular prokaryotic microorganisms that live in normal environmental conditions. On the other hand, Archaea (Archaebacteria) are prokaryotic older organisms that thrive in extreme conditions (in this case, volcanic ash). Moreover, eukaryotic organisms can be classified into four kingdoms: Protista, Plantae, Fungi and Animalia. Protista are unicellular eukaryotes that live in different aquatic environments (i.e., oceans, ponds, streams, etc). Animals are multicellular, mobile, heterotrophic (i.e., organisms that cannot produce its own food) organisms whose cells lack walls. Fungi are heterotrophic organisms that acquire their food by absorbing dissolved organic compounds, whose cells have cell walls (but they lack chloroplasts). Finally, plants are multicellular autotrophic (i.e., organisms that produce their own food) organisms whose cells contain walls and chloroplasts (to produce food by photosynthesis).

Which kingdom includes multicellular, heterotrophic organisms that absorb nutrients from other dead organisms?

Protista
Animalia
Plantae
Fungi

Compare and contrast suspension feeding and deposit feeding-

Answers

Answer:

Suspension feeding involves collecting food particles like small organisms, organic matter, detritus which are suspended in water, often using some form of filtration.

Suspension feeders catch food or organic material from the water using tentacles or spiny arms

where as

Deposit feeding involves feasting on detritus and organic matter that have settled on the ocean floor.

Deposit feeders pass sand, mud, water or sediment into their mouths using mucous-covered tentacles or arms etc.

Explanation:

Suspension feeding ingests the food particles which are suspended in water, while deposit feeding ingests sediments and aquire foods.

What do you mean by Deposit feeders?

Deposit feeders may be defined as those aquatic organisms that forage on organic matter that settled down on the bottom.

Suspension feeding maintains the water quality in the aquatic environment, while deposit feeding enhances oxygen level and nutrient cycling.

Suspension feeding occurs similarly to filter-feeding that only ingests suspended particles. While deposit-feeding ingests the deposited particles like detritus, organic matter, etc.

Therefore, it is well described above.

DNA has a double- helix structure which means it has two strands. The DNA strands are made from sugar (Deoxyribonucleic), phosphates and nitrogenous bases. There are 4 nitrogenous bases, 2 purine and 2 pyrimidine. The 2 purine bases are Adenine and Guanine. The pyrimidine bases are Thymine and Cytosine. DNA gives our genes.

RNA is a single strand unlike DNA. The strands are made from sugar (ribonucleic), phosphate and the nitrogenous bases. There are 4 nitrogenous bases 2 purine and 2 pyrimidine. The 2 purine bases are Adenine and Guanine. However, the 2 pyrimidine bases are Uracil and Cytosine. The function of RNA is to contribute to releasing proteins based on our rRNA and tRNA and mRNA. This process is known as RNA and transcription.
