Answer: (edited)  Actually it might be D

Explanation: ATP (adenosine triphosphate) makes food for your body, and we can only keep a small amount of ATP and glucose stored in our bodies at a time. When you run, your body is trying to create extra ATP. In order to do that, you need more oxygen intake, so you start breathing heavier and quicker.

(a) if the seawater carbonate ion concentration is 270 ?mol/kg, what is the approximate rate of calcification, and approximately
Travka [436]
Using the graph provided with the question, we are able to find that that for a concentration of 270 micromol per kilogram, the calcification rate is 20 mmol calcium carbonate per meter squared per day.

Using this calcification rate,
30 = 20 * 1 * days

days = 1.5

The deposition will require 1.5 days.

Which microscope would be used to observe surface structure of corona virus?
ElenaW [278]

Answer:

SEM ANSWER

Explanation:

Electron microscopy is a powerful tool in the field of microbiology. It has played a key role in the rapid diagnosis of viruses in patient samples and has contributed significantly to the clarification of virus structure and function, helping to guide the public health response to emerging viral infections. In the present study, we used scanning electron microscopy (SEM) to study the infectious cycle of SARS-CoV-2 in Vero E6 cells and we controlled some key findings by classical transmission electronic microscopy (TEM). The replication cycle of the virus was followed from 1 to 36 h post-infection. Our results revealed that SARS-CoV-2 infected the cells through membrane fusion. Particles are formed in the peri-nuclear region from a budding of the endoplasmic reticulum-Golgi apparatus complex into morphogenesis matrix vesicae. New SARS-CoV-2 particles were expelled from the cells, through cell lysis or by fusion of virus containing vacuoles with the cell plasma membrane. Overall, this cycle is highly comparable to that of SARS-CoV. By providing a detailed and complete SARS-CoV-2 infectious cycle, SEM proves to be a very rapid and efficient tool compared to classical TEM.

List two reasons why cells need to be small.
Sonja [21]

Answer:

they need a high ‘surface to volume’ ratio, which is good for exchanging materials between the inside and outside of cells. But this is probably not really the size-limiting reason, since cells vary enormously in size and surface area to volume ratios.

Stels [109]
The biosphere is made up of all living things (organisms). 

The biosphere includes animals, biomes, population, communities, and ecosystems. The biomes are climate regions which can contain certain types of animals and plants. An ecosystem is all living things in one specific area, also such as plants, animals, and organisms.
