Answer:
no the molecules tend not to push away from each other
Answer: No/False
Explanation: Water molecules stick together because of cohesion. Depending on how attracted molecules of the same substance are to one another, the substance will be less or more cohesive. Hydrogen bonds cause water to be more attracted to each other, therefore making them stick together.
In this activity, you will identify the conclusions that can be drawn from Pasteur's experiments using S-shaped neck flasks. Which of the following conclusions can be drawn from Pasteur's experiment involving the flasks with S-shaped necks? Select all statements that apply. a. 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.
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.
Read the observation, question, and hypothesis. Then, choose the dependent variable from the list. Observation: Most hummingbird feeders are red. Question: Are hummingbirds attracted to the color red? Hypothesis: Hummingbirds are more attracted to red feeders than nonred feeders. The dependent variable in this case is the color red. hummingbird feeders. hummingbird behavior. bird watching.
Answer:
hummingbird behavior
Explanation:
depends on color of bird feeder
what two methods do scientists use to gather information

Explanation:
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
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

Answer:
The cell membrane can be compared to the school gates.
Explanation:
Cell membranes only let in specific molecules (people), large substances (old people) cannot cross it while smaller molecules like oxygen (students) can easily pass through the membrane.

Answer:I think it’s outsourcing
Explanation:
true or false ? Cell membranes are selectively permeable, allowing only some materials to cross the cell membrane. This
property allows cells to maintain homeostasis.
Answer:
True
Explanation:
Cell membranes are selectively permeable because of the structure of the phospholipid bilayer.
This bilayer only lets certain things in because it depends on the polarity, size, and type of molecule.
For example, glucose molecules are too large to enter. But, carbon dioxide molecules can go in and out easily because of their small size.
Answer:
This statement is True
“One way that a cell maintains homeostasis is by controlling the movement of substances across the cell membrane. The lipid bilayer is selectively permeable to small, nonpolar substances. Proteins in the cell membrane include cell-surface markers, receptor proteins, enzymes, and transport proteins.”

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