Esophagus - move food from mouth to stomach through a process called peristalsis
Stomach - chemically break down food with stomach acid, mechanically break down food with the contracting of stomach muscles
Liver - creates bile that helps with digestion, stores, distributes and breaks down nutrients
Gallbladder - temporarily stores bile and squeezes it into the small intestine to break down fat droplets
Pancreas - produces pancreatic juice that contains digestive enzymes and bicarbonate
Small Intestine - absorbs nutrients from chyme
Large Intestine - absorbs water and dries out food, turning it into waste
Rectum - stores waste before it leaves the body

Which describes a difference between bivalves and cephalopods?
Bivalves use tube feet for movement, and cephalopods use muscular feet for movement.
Bivalves live only in ocean environments, and cephalopods live in a variety of aquatic environments.
O Bivalves use a radula to feed, and cephalopods use filter-like structures to feed.
O Bivalves have an open circulatory system, and cephalopods have a closed circulatory system.
Answer: D - Bivalves have an open circulatory system, cephalopods have a closed circulatory system
Explanation: I had to research the differences to find the answer
A difference between bivalves and cephalopods are bivalve animals use a radula to feed, and cephalopods use filter-like structures to feed, that is the third option, where they both belong to the Mollusca phylum.
What is the significance of bivalves and cephalopods?Both bivalves and cephalopods belong to the mollusca phylum, and they are invertebrates, some of the bivalves, such as oysters and mussels, are important as they are a source of food for humans and as filter-feeding organisms; at the same time, squid and octopus are cephalopods. These organisms are significant in different fields of study, such as neuroscience and evolution.
Hence, a difference between bivalves and cephalopods are bivalve animals use a radula to feed, and cephalopods use filter-like structures to feed, that is the third option, where they both belong to the Mollusca phylum.

Explanation:
Are the fatty acid tails saturated or unsaturated?
and What type of lipid is shown in the picture?
Answer:
The fatty acid tails saturated or unsaturated is discussed below in details.
Explanation:
Fatty acids contain a carboxylic acid association and a great hydrocarbon series, which can either be saturated or unsaturated. A saturated fatty acid tail only contains carbon-carbon individual bonds, and an unsaturated fatty acid has at the slightest individual carbon-carbon twice or triples bond.
Describe how transposable elements create mutations within an organism and how transposable elements facilitate chromosomal rearrangements.
Answer:
Transposable elements are discrete segments of DNA that can be excised and reintegrated to another site in the genome, these can inactivate the gene in which they reside, cause chromosome breaks, and / or transpose to a new location within the genome.
Explanation:
Transposable elements are fragments of DNA that have the ability to jump from one part of the genome to another. While most of the DNA is always in the same place surrounded by the same neighboring pieces of DNA, mobile elements move from one place to another causing many changes or mutations. When a transposon moves through the genome, it can insert into a vital gene, disrupting its function, or into a location near vital genes, causing erroneous activation or inactivation.On the other hand, there can be chromosomal rearrangements due to transposons of the same family with complementary sequences that are separated in the genome and that by sequence homology match. This can lead to ectopic recombination. Large-scale rearrangements induced by mobile elements are considered a particular class of recombination events that influence genomic plasticity.
what are the steps in the digestion of protein
Explanation:
Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids.

Which of the following is NOT a property of water?
O A) It is a good solvent.
OB) It is denser when frozen than when liquid.
OC) It resists temperature changes.
OD) it is cohesive.
O El It can be found as a solid. liquid. or gas.
Answer:
It is denser when frozen than when liquid.
Explanation:
Ice is actually less dense than water. The lattice arrangement of ice allows water molecules to be more spread out than in a liquid, making ice less dense than water.

Which of the following factors most likely triggers arousal from hibernation?
A) the sun rising in the morning B)snow falling onto the ground
C) the environmental temperature dropping below 0 °C
D) a significant decrease in the animal's respiration rate
Answer:
A) the sun rising in the morning
Explanation:
In biology, hibernation refers to a physiological state where a plant or animal is metabolically inactive in the winter period (characterized by extreme cold). As far as the animal or plant is concerned, the cold weather during winter is an adverse condition, hence, they undergo hibernation in order to conserve their energy.
According to this question, arousal or wakening from hibernation would be triggered in the presence of heat source, which in this case is the SUN RISING IN THE MORNING.

Solar energy is the renewable source of energy. So, the correct option is A.
What is Renewable resources?A natural resource that can be replenished to replace the portion used up by usage and consumption is known as a renewable resource, furthermore known as a flow resource. This replenishment can occur naturally through reproduction or through other recurring processes in a limited amount of time on a human time scale.
Renewable energy is generated by renewable resources that replace themselves more quickly than they are used up. Examples of these sources that are continuously replenished are the sun and the wind.
Solar energy, wind, falling water, geothermal heat from the soil, biomass from plants, waves, ocean currents, temperature variations in the oceans, and tide energy are all examples of renewable resources.
Therefore, the correct option is A.
