Pasteur's observations support the theory of spontaneous generation. b. Microbes can be blocked from accessing favorable growth environments. c. Beef broth is an unsuitable environment for growing microorganisms. d. Microbial life can be destroyed by heat. e. Microorganisms can be present in nonliving matter, such as air, liquids, and solids. f. Microbial life can arise from nonliving matter. g. Pasteur's observations support the theory of biogenesis.

Answers

Answer:

The correct answer would be :

b. Microbes can be blocked from accessing favorable growth environments.

d. Microbial life can be destroyed by heat.

e. Microorganisms can be present in nonliving matter, such as air, liquids, and solids.

g. Pasteur's observations support the theory of biogenesis.

Explanation:

Pasteur's experiment with s-shaped neck flasks indicated that organisms can't emerge from nonliving materials under the conditions that existed on Earth during his lifetime.

It helps in testing the role of airborne contaminants in producing microbes in the nonliving matter by the biogenesis theory. His experiment showed and supports that heat can kill or destroy microbial life.

Thus, the correct answer would be -  b., d, e., and g.

Choose the best description, definition for Uniformitarianism. Please help im failing badly

Answers

Answer:

The correct answer is b. The principle of Uniformitarianism is based on the idea that Earth´s physical landscape is the result of processes and forces that have happened uniformly since the earth formed.  

Explanation:

Stated by the geologist James Hutton, this principle says basically that all the geological processes that currently occur had also occurred in the past. Based on this principle, many events might be explained, and not only geological events, but also biological events.

The Uniformitarianism or Uniformism principle states that all the processes that have occurred during the whole Earth history, have been uniform (that is why this principle is named Uniformitarianism) and similar to the current processes.

This principle is very important nowadays, but knowing that not all processes are completely uniform, they have been changing heir intensity and rhythm. Besides, there is a very important factor that is not repeatable, living organisms, that have been lineally changing throughout history.

A table of four types of carbohydrates is shown below. Which list correctly matches the functions to the types of carbohydrates? Type of carbohydrate Cellulose Chitin Description Major component of plant cell walls Major component of fungal cell walls and arthropod exoskeletons Stored in liver and muscle cells, broken down to glucose when blood glucose levels decrease Glycogen Starch Stored in plant roots and seeds, provides food for seeds to germinate or for animal consumption A Energy: glycogen and starch & Structure: cellulose and chitin B Energy: cellulose and chitin & Structure: Glycogen and starch С Energy: chitin and glycogen & Structure: cellulose and starch D Energy: cellulose and starch & Structure: chitin and glycogen​

Answers

Answer is A:

Explanation:

Glycogen and starch are for ENERGY while cellulose and chitin are for STRUCTURE

Polysaccharides are complex carbohydrate molecules formed from monomeric molecules called monosaccharides. Polysaccharides perform varying functions in living organisms that possess them.

The types of polysaccharides that we have are as follows:

Cellulose: Cellulose is the major component of plant's cell wall. It gives the cell additional structural strength.

Chitin: Chitin is the major component found in the cell wall of fungi and exoskeletons of arthropods where it provides structural strength.

Glycogen: Glycogen is the form of carbohydrate glucose is converted to when in excess in the bloodstream. It is stored in the liver and muscles. Glycogen is changed back to glucose when it is needed for energy production.

Starch: Starch is the form by which plant cells store food. It is stored in the root and seed of plants. Starch is broken down into glucose when need arises for energy.

Therefore, glycogen and starch are for ENERGY while cellulose and chitin are for STRUCTURE
