Answer:
Digestion starts with the sight, thought, or smell of food. When the brain anticipates an incoming meal, the vagus nerve sends a message to the stomach causing the release of acetylcholine. The binding of acetylcholine to G cells in the stomach starts the secretion of gastrin and, in combination with acetylcholine and histamine, stimulates parietal cells in the gastric glands of the stomach body to start secreting hydrochloric acid (HCl).

Prokaryotic and eukaryotic cells have several differences. Which statement below is not one of those
differences?
Prokaryotic cells are found in the domains Eubacteria and Archaea.
Eukaryotic cells have organelles for processes like respiration or photosynthesis.
Prokaryotic cells cannot make their own proteins.
Eukaryotic cells are generally ten times larger than prokaryotic cells.
prokaryotic cells cannot make their own proteins, the statement is false. Thus the option C is correct.
What are the distinguishable features of prokaryotes and eukaryotes ?Prokaryotic cell are unicellular as it is made up of single cell and the size ranges from 0.2 μm – 2.0 μm while eukaryotic cell are multi-cellular, the size ranges from 10 μm – 100 μm in diameter.
cell wall is present in prokaryotes which involve in providing protection of the cell where as only in plant cell wall is present; True Nucleus is absent in prokaryotes instead of nucleus, nucleoid is present which carry genetic material while in eukaryotes true nucleus is present.
The Ribosomes are Smaller in size and 70s type in prokaryotic cell where as the ribosome is larger in size with 80s type in eukaryotic cell larger in size and linear shaped ribosomes are present.
All the metabolic and physiological activities occur in a single cell of prokaryotes where as the metabolic and physiological activities occur in different organelle.
Thus the option C is correct.

What is enzymes Bc i dont know what that is
Answer:
Enzymes are proteins that act as biological catalysts. Catalysts accelerate chemical reactions. The molecules upon which enzymes may act are called substrates, and the enzyme converts the substrates into different molecules known as products.

Passive transport is the movement of substances across a cell membrane without the use of
Answer:
Image result for Passive transport is the movement of substances across a cell membrane without the use of
Passive transport is a movement of ions and other atomic or molecular substances across cell membranes without need of energy input. Unlike active transport, it does not require an input of cellular energy because it is instead driven by the tendency of the system to grow in entropy.

Imagine a science fiction movie in which a scientist creates a new species of organism. The scientist generates a whole population of the organism entirely through cloning of the males and females and then leaves them on an island. Explain why the population of clones would struggle to evolve if there was a major environmental change on the island.
The population of clones that struggle to evolve if there was a major environmental change on the island is :
-Lack of variations in the population as the clones are products of without fusion reproduction.
"Environmental change"The population of clones will struggle due to lack of variations in the population as the clones are products of without fusion reproduction.
Without fusion reproduction will allow the parent organism to produce offspring that are exactly identical to the parent.
Also it will help in production of large number of progenies at a single time.
Therefore, the population of clones will struggle due to lack of variations in the population as the clones are products of without fusion reproduction.

Is human survival independent of other species?
Explanation:
As far as I can think of, we're dependent on other species. If we can't be carnivores, then literally, the only other option I can think of is being a herbivore, and that still an organism. We need sufficient life essence to keep living. We CANNOT live without harming another organism.
In short of my babbling, human survival is not independent of other species.

1 point
Lipase
Lactose
Amylase
Xylase
Cellulose
Glucose
Fructase
Fructose
Lactase
NONE OF THESE!!!
Answer:
Lipases, Amylase, Lactase, and Cellulase. Did this Help?
Explanation:
Lipases – a group of enzymes that help digest fats in the gut.
Amylase – helps change starches into sugars. Amylase is found in saliva.
Maltase – also found in saliva; breaks the sugar maltose into glucose. Maltose is found in foods such as potatoes, pasta, and beer.
Trypsin – found in the small intestine, breaks proteins down into amino acids.
Lactase – also found in the small intestine, breaks lactose, the sugar in milk, into glucose and galactose.
Acetylcholinesterase – breaks down the neurotransmitter acetylcholine in nerves and muscles.
Helicase – unravels DNA.
DNA polymerase – synthesize DNA from deoxyribonucleotides.
Cellulase -- is any of several enzymes produced chiefly by fungi, bacteria, and protozoans

Answer:
an operational definition
Explanation:
Answer:
operational definition
Explanation:
An operational definition is a statement that describes how to measure a particular variable or define a particular term. For example, in this experiment you would need to determine what sounds will count as a single “chirp.”
