A fixed action pattern is a behavior that is carried out to completion once started, regardless of changes in the original stimulus and the sequence is unchangeable. The unlearned behavior of fixed action patterns are triggered by a type of external stimulus that start off a particular organism.

A student has a sandwich for lunch. The bread contains starch molecules and various other molecules. After chewing and swallowin
kupik [55]

Answer:

Once starch reaches small intestine, it needs to be broken down into smaller units with the help of <u>hydrolysis reaction</u>. Pancreatic amylase catalyzes this reaction which ultimately breaks down glycosidic bonds present in starch molecule to produce simpler bio-molecules like maltose, dextrin etc.

Uses of carbohydrate in body:

(1) It is primary source of energy in the body;

(2) It is required by the body for storage of energy in the form of glycogen;

(3) In plants, it is required for building cellular structures like cellulose.

Explanation:

In order for starch to be digested in the intestine, it needs to be hydrolyzed with the help of pancreatic amylase. The hydrolysis reaction breaks the glycosidic bonds of starch molecule which is a polymer leading to the release of smaller molecules like dextrin, maltose etc. Maltose which is a disaccharide is further broken down into even smaller monomeric units like glucose with the help of enzyme known as maltase.

After conversion into monomeric unit i.e. glucose now it can be absorbed by the blood stream. The blood transports these small glucose molecules to all the cells of the body. After entering the cell, the glucose is used for the production of energy/ATP via cellular respiration.

During cellular respiration, the glucose is first converted into pyruvate via glycolysis. Pyruvate then enters PDH complex wherein it is oxidatively carboxylated into acetyl coenzyme A. The acetyl coenzyme A produced then enters TCA cycle and produce high energy molecules like NADH, FADH₂ and ATP. The NADH and FADH₂ then finally enter electron transport chain (ETC) so as to produce ATPs. These ATPs are then utilized by our body for our day to day activities.

Analysis in which general conclusions are drawn from specific observations is called
AnnZ [28]

Answer: Option B

Inductive reasoning.

Explanation:

It is inductive reasoning because inductive reasoning is a type of reasoning in which general informations are made based on some specific observations or information even when the conclusion is not complete guaranteed to be true.

This means that you make a guess's or generalizations based on the information you have at hand.

For example; The left handed people the you know uses left hand in right and you now make the conclusion that all left handed people write with their left hand only.

includes all descendants from a single common ancestor. does not share any common ancestry but represents convergent evolution.
Tju [1.3M]

Answer:

Phylogenetic relationships

1. includes all descendants from a single common ancestor >>> monophyletic group

2. does not share any common ancestry but represents convergent evolution >>> polyphyletic group

3. includes some but not all descendants from a single common ancestor >>> paraphyletic group

Explanation:

A monophyletic taxon is a collection of organisms that have the same most recent common ancestor, thereby including an ancestor and all its descendants. Examples of monophyletic groups are angiosperms, mammals, insects, etc. A paraphyletic group is composed of some (but not all) the descendants of the most recent common ancestor. An example of a paraphyletic group includes fish and lizards. Finally, a polyphyletic taxon is composed of a group of organisms that do not contain the common ancestor of all the members of the group. An example of a polyphyletic group is composed of birds and mammals, (which constitutes a group of warm-blooded animals).

Organisms which can make their own food are found in this kingdom:
velikii [3]
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.
