Answer:

Convection is the transfer of heat due to the bulk movement of molecules within fluids, including molten rock.

Explanation:

Answer 2

Answer: (a current in a fluid that results from convection.)

Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock. The heat transfer function of convection currents drives the earth’s ocean currents, atmospheric weather and geology. Convection is different from conduction, which is a transfer of heat between substances in direct contact with each other.

Why are cortisol analogues such as prednisone used for treating asthma?

Answers

Solution:

prednisone, are primarily used for their potent anti-inflammatory effects in disorders of many organ systems it works as it is absorbed in the body, unlike inhaled steroids (anti-inflammatory asthma inhalers) that go straight to the lungs. ... Prednisone and other systemic steroids may be used to treat asthma attacks and help people gain better asthma control.

Tina conducted an experiment to test her hypothesis. Her hypothesis was that by crushing aspirin and putting it into potting soil increases the growth rate of tomato plants. The results of the experiment show that there was no significant difference in the growth rates between the control and the experimental groups. What should Tina do with the results of this experiment?

Answers

Tina should think about results and why aspirin did not affect the growth rate of tomato plants. She may find the answer in literature or can apply the results on the new situation. She may change the hypothesis and alter some factors in the experiment to test the new hypothesis.

2.) Unlike photosynthesis, cellular respiration occurs in (1 point)A. Animal Cells Only
B. Plant Cells Only
C.prokaryotic cells only.
D.all eukaryotic cells.

Answers

Unlike photosynthesis, cellular respiration occurs in all the eukaryotic cells. Thus, the correct option is D.

What is Cellular respiration?

Cellular respiration is the process by which the biological fuels such as carbohydrates (glucose sugar) are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy-rich compounds, to drive the bulk production of ATP molecule. This process occurs in all types of eukaryotic cells including plant cells and animal cells.

Photosynthesis is the process of formation of food in the form of carbohydrate (glucose) in the presence of sunlight and carbon dioxide in the chloroplast of plant cell and organisms which contain a chloroplast.

Therefore, the correct option is D.

Bacteria that are shaped like rods are called?A. cocci
B. spirilli
C. bacilli
D. filamentous

Answers

Bacteria aresingle celled microorganisms. They have a simple cell structure than otherorganisms because they have no nucleus and no cell membrane. Their controlcenter containing the genetic information si contained in a single loop of DNA.They are classified into five groups according to their shape; cocci arespherical, bacilli are rod shaped, spirilla are spiral, vibrios are comma andspirochaetes are corkscrew. They can exist as singe cells in pairs, chains orclusters. Rod shaped bacteria are called bacilli. The answer is letter C.

Final answer:

The term for rod-shaped bacteria is 'bacilli'. This category is a part of the larger classification in microbiology based on bacterial shape, which also includes cocci for spherical bacteria and spirilli for spiral-shaped bacteria.

Explanation:

In the field of Biology, particularly microbiology, bacteria are often categorized based on their shape. For bacteria that are shaped like rods, the term used is bacilli. This contrasts with other shapes, such as cocci (spherical) and spirilli (spiral-shaped). For instance, Bacillus subtilis is a type of rod-shaped bacteria, which demonstrates the morphological type bacilli.

The correct answer is C. bacilli. Bacteria that are shaped like rods are called bacilli. These bacteria have a cylindrical shape and can be found in various environments, such as soil, water, and the human body. Some examples of bacilli include E. coli and Salmonella.
